ABSTRACT

Animals exhibit sociability behaviors and spatial use patterns that are important for species survival. Bats are animals that exhibit complex patterns of aggregation of individuals, which can vary according to sex and age. Aggregation can be explained by active or passive mechanisms. In this behavioural note, we report a group of female Artibeus lituratus in the reproductive stage that exhibits aggregation behavior supporting the active mechanism hypothesis. The females returned to the same roost, for two reproductive season, maintaining the aggregation with the same individuals with which the social bonds were already established.


Os animais exibem comportamentos de sociabilidade e padrões de uso espacial que são importantes para a sobrevivência das espécies. Os morcegos são animais que apresentam padrões complexos de agregação de indivíduos, que podem variar de acordo com o sexo e a idade. A agregação pode ser explicada por mecanismos ativos ou passivos. Nesta nota comportamental, relatamos um grupo de fêmeas de Artibeus lituratus em fase reprodutiva que exibe comportamento de agregação apoiando a hipótese do mecanismo ativo. As fêmeas retornaram ao mesmo poleiro, por duas estações reprodutivas, mantendo a agregação com os mesmos indivíduos com os quais os laços sociais já foram estabelecidos.

ABSTRACT

Resumen Introducción: En el Pacífico central mexicano son escasos los trabajos sobre ecología de asteroideos. Estas especies generalmente se distribuyen de forma aleatoria, aunque en algunas ocasiones pueden encontrarse en grupos o agregaciones. En Los Arcos, al sur de Puerto Vallarta, en Bahía de Banderas, México, se observó Luidia bellonae por primera vez en una agregación masiva en 2021. Objetivo: Reportar por primera vez el registro de esta especie en esta región del Pacífico mexicano, así como el evento de agregación masiva. Métodos: Se realizaron transectos y recorridos para cuantificar la densidad y medir los ejemplares de la estrella en Los Arcos, Bahía de Banderas, durante 2021, 2022 y 2023. Resultados: Se encontraron densidades promedio de 2.65 ind/m2 y hasta 7 ind/m2. En total en el área aproximada de 900 m2 se registraron 630 individuos. Los ejemplares midieron (R) entre 2 y 12 cm, y en su mayoría midieron entre 4 y 8 cm. Conclusiones: L. bellonae estaba reportada en distintos sitios en algunos estados del Pacífico mexicano, sin embargo no estaba registrada para Bahía de Banderas ni Los Arcos, ni tampoco en la cantidad que se reporta aquí, por lo que este es el primer registro para la especie con una presencia masiva para el Pacífico mexicano. La aparición de la gran cantidad de ejemplares de L. bellonae en Los Arcos en 2021 pudo haber sido resultado de una combinación de factores, entre ellos la baja temperatura del agua, con valores hasta de 15 ºC y la alta cantidad de nutrientes. Este hallazgo demuestra la necesidad de más estudios sobre los equinodermos y especies marinas para entender la influencia que tienen las condiciones ambientales en su ciclo de vida.


Abstract Introduction: In the central Mexican Pacific, there are few studies on asteroid ecology. These species are generally distributed randomly, although in some cases groups or aggregations can be found. In Los Arcos, south of Puerto Vallarta, in Bahía de Banderas, Mexico, Luidia bellonae was observed for the first time in a massive aggregation in 2021. Objective: To report the new record of this species in this region of the Mexican Pacific and its massive aggregation event. Methods: Transects and surveys were carried out to quantify the density and measure the sea star individuals in Los Arcos, Bahía de Banderas during 2021, 2022, and 2023. Results: Average densities of 2.65 ind/m2 and up to 7 ind/m2 were found. In total, in the approximate area of 900 m2, 630 individuals were registered. The specimens measured (R) between 2 and 12 cm, and most measured between 4 and 8 cm. Conclusions: L. bellonae has been reported in different places in some states of the Mexican Pacific; however, it was not registered for Bahía de Banderas nor Los Arcos, nor in the amount reported here, therefore this is the first record for the species with a massive presence for the Mexican Pacific. The appearance of the large number of L. bellonae specimens in Los Arcos in 2021 could have been the result of a combination of factors, including the low water temperature, with values up to 15 ºC, and the high amount of nutrients. This finding demonstrates the need for more studies on echinoderms and marine species to understand the influence of environmental conditions on their life cycle.

ABSTRACT

Resumen Introducción: Los equinodermos son animales estrictamente acuáticos y de los grupos de invertebrados marinos cuya importancia ecológica es crucial para los ambientes en donde habitan. La característica más destacada es su simetría pentarradial. Estos organismos pueden distribuirse en una amplia variedad de ambientes oceánicos, y no ser exclusivamente habitantes de las formaciones arrecifales. Se han registrado el total de 1 539 especies, de las cuales 717 pertenecen a Pacífico y 60 de ellas se han registrado en El Salvador. Objetivo: El objetivo del trabajo fue registrar la riqueza y densidad de especies de equinodermos en arrecifes rocosos de Punta Amapala (La Unión). Métodos: El muestreo fue llevado a cabo en cinco sitios, dos a 3 m de profundidad y tres a 6 m. Para esto, se utilizó snorkeling y buceo autónomo, recorriendo dos transectos de banda de 30 x 1 m. Dentro de los transectos, se realizó la identificación (riqueza) y contabilización (abundancia) de los organismos. Resultados: La especie que presentó mayor densidad en los arrecifes de 3 m fue Echinometra vanbrunti (0.83 indv/m2), seguido por el ofiuroideo Ophiocomella alexandri (0.16 indv/m2) y Ophiocoma aethiops (0.16 indv/m2). Y en los arrecifes a 6 m fueron Ophiothela mirabilis (0.83 indv/m2), Ophionereis annulata (0.21 indv/m2), Ophiothrix rudis (0.08 indv/m2) y Ophiocomella alexandri (0.01 indv/m2). Conclusiones: Estos organismos, cumplen con diversos roles ecológicos, como ser bioindicadores de calidad de agua al tolerar ciertos cambios en las condiciones físico-químicas, así como cumplir el papel de hospederos de macrofauna por las cavidades que forman algunos erizos. Es por ello que los esfuerzos de muestreo deben incrementarse en estas zonas para monitorear la calidad y salud de los arrecifes rocosos, cuyo papel es clave, por ser junto con Los Cóbanos, los de mayor extensión en el país.


Abstract Introduction: Echinoderms are strictly aquatic animals and one of the groups of marine invertebrates whose ecological importance is crucial for the environments where they inhabit. The most outstanding characteristic is their pentaradial symmetry. These organisms can be distributed in a wide variety of oceanic environments, and are not exclusive inhabitants of reef formations. A total of 1 539 species have been registered, of which 717 belong to the Pacific and 60 of them have been registered for El Salvador. Objective: The objective of the work was to record the richness and density of echinoderm species in rocky reefs of Punta Amapala (La Unión). Methods: The sampling was conducted in five sites, two of them at 3 m of depth and three at 6 m. For this, snorkeling and autonomous diving were used, covering two band transects of 30 x 1 m. Within the transects, the identification (richness) and counting (abundance) of the organisms was carried out. Results: The species that presented the highest density at 3 m reefs was Echinometra vanbrunti (0.83 indv/m2), followed by the ophiuroid Ophiocomella alexandri (0.16 indv/m2) and Ophiocoma aethiops (0.16 indv/m2). And at the 6 m reefs were Ophiothela mirabilis (0.83 indv/m2), Ophionereis annulata (0.21 indv/m2), Ophiothrix rudis (0.08 indv/m2) and Ophiocomella alexandri (0.01 indv/m2). Conclusions: These organisms fulfill various ecological roles, such as being bioindicators of water quality by tolerating certain changes in physicochemical conditions and fulfilling the role of macrofauna hosts due to the cavities formed by some sea urchins. That is why sampling efforts must increase in these areas to monitor the quality and health of the rocky reefs, whose role is key, as they are, together with Los Cóbanos, the largest in the country.

ABSTRACT

Abstract Introduction: Echinoderms, an integral component of marine ecosystems worldwide, have captivated scientific interest for centuries. Despite this longstanding attention, comprehending key facets such as trophic relationships, diet composition, and host-microbiota relationships still represents a challenge using traditional techniques. Recent years, however, have witnessed a transformative shift, thanks to the emergence of advanced molecular techniques, offering new approaches to strengthen ecological studies in echinoderms. Objective: Explore how recent advancements in molecular tools have impacted ecological research on echinoderms. Specifically, we aim to investigate the potential of these tools to shed light on trophic interactions, diet composition, and the characterization of gut microbial communities in these organisms. Methods: Available literature was used to clarify how novel molecular techniques can improve ecological studies. The focus is diet, trophic relationships, and gut microbiota. Results: Traditionally, studies of stomach contents using compound microscopy have provided an idea of ingested material; nevertheless, sometimes a simple magnified visualization of dietary content does not allow exhaustive identification of the entire food spectrum, as it is limited due to the rapid digestion and maceration of food items within the echinoderm's digestive tract. The use of DNA-metabarcoding, targeting specific DNA regions, such as the mitochondrial COI gene, has allowed us to enhance the accuracy and precision of diet characterization by enabling the identification of prey items down to the species or even genetic variant level, providing valuable insights into specific dietary preferences. Another approach is the use of stable isotopes, particularly carbon and nitrogen, which provide a powerful tool to trace the origin and flow of nutrients through food webs. By analyzing the isotopic signatures in muscular tissues and food items, we can discern the sources of their primary food items and gain insights into their trophic position within the ecosystem. Lastly, a third new technique used to elucidate the characterization of the prokaryotic community is 16S rRNA sequencing. This method allows us to explore the composition and dynamics of the digestive tract microbial communities. Conclusions: This is a promising era for ecological research on echinoderms, where advances of molecular tools have enabled an unprecedented level of detail, resolving longstanding challenges in comprehending their trophic interactions, diet composition, and host-microbiota relationships, and opening new avenues of investigation in ecological studies.


Resumen Introducción: Los equinodermos, un componente integral de los ecosistemas marinos en todo el mundo, han captado el interés científico durante siglos. A pesar de esta prolongada atención, el comprender facetas clave como las relaciones tróficas, la composición de la dieta y las relaciones huésped-microbiota todavía representa un desafío utilizando técnicas tradicionales. Sin embargo, los últimos años han sido testigos de un cambio transformador, gracias a la aparición de técnicas moleculares avanzadas, que ofrecen nuevos enfoques para fortalecer los estudios ecológicos en equinodermos. Objetivo: Explorar cómo los avances recientes en herramientas moleculares han impactado la investigación ecológica sobre equinodermos. Específicamente, nuestro objetivo es investigar el potencial de estas herramientas para arrojar luz sobre las interacciones tróficas, la composición de la dieta y la caracterización de las comunidades microbianas intestinales en estos organismos. Métodos: Se utilizó la literatura disponible para aclarar cómo las nuevas técnicas moleculares pueden mejorar los estudios ecológicos. La atención se centra en la dieta, las relaciones tróficas y la microbiota intestinal. Resultados: Tradicionalmente, los estudios del contenido estomacal mediante microscopía compuesta han proporcionado una idea del material ingerido; Sin embargo, a veces una simple visualización ampliada del contenido dietético no permite una identificación exhaustiva de todo el espectro alimentario, ya que está limitado debido a la rápida digestión y maceración de los alimentos dentro del tracto digestivo del equinodermo. El uso de metabarcoding de ADN, dirigidos a regiones específicas del ADN, como el gen COI mitocondrial, nos ha permitido mejorar la exactitud y precisión de la caracterización de la dieta al permitir la identificación de presas hasta el nivel de especie o incluso de variante genética, lo que proporciona valiosos resultados sobre preferencias dietéticas específicas. Otro enfoque es el uso de isótopos estables, en particular carbono y nitrógeno, que proporcionan una poderosa herramienta para rastrear el origen y el flujo de nutrientes a través de las redes alimentarias. Al analizar las firmas isotópicas en los tejidos musculares y los alimentos, podemos discernir las fuentes de sus alimentos primarios y obtener información sobre su posición trófica dentro del ecosistema. Por último, una tercera técnica nueva utilizada para dilucidar la caracterización de la comunidad procariótica es la secuenciación del ARNr 16S. Este método nos permite explorar la composición y dinámica de las comunidades microbianas del tracto digestivo. Conclusiones: Esta es una era prometedora para la investigación ecológica sobre equinodermos, donde los avances de las herramientas moleculares han permitido un nivel de detalle sin precedentes, resolviendo desafíos de larga data en la comprensión de sus interacciones tróficas, composición de la dieta y relaciones huésped-microbiota, y abriendo nuevas vías de investigación. en estudios ecológicos.

ABSTRACT

ABSTRACT Ecological interactions are diverse, variable across space and time and not always well understood. The use of interaction network analysis has become a tool that promotes a deeper understanding on ecological and evolutionary processes. The interaction between insects and fungi is an interesting research model, helping to understand colonization dynamics and species specialization in spatially aggregated and ephemeral resources. Here, we describe the interactions between Drosophilidae species and the fungal basidiocarps in a subtropical forest in Brazil. Flies were collected when were visiting basidiocarps and then the basidiocarps themselves were also collected to obtain the emerging flies whose larvae fed on the fungi. We observed 31 species of drosophilids interacting with basidiocarps of 23 fungi species. An ecological network analysis was performed for the drosophilids breeding on basidiocarps and for those visiting them as adults. We found a specialized breeding network, with stronger interactions involving Hirtodrosophila and Auricularia and Zygothrica bilineata and a Marasmius species. Our results indicate the generalist habit of most Zygothrica species. The visitation network was highly specialized. Despite being well represented in the sampling, most Zygothrica species did not emerge from any fungal species. This study advances the knowledge on patterns of Drosophilid-fungi interactions and provides insights into their drivers.

ABSTRACT

ABSTRACT Brazil has been suffering a dengue (DENV) epidemic in 2019 and 2022 and records cases of Zika (ZIKV) and chikungunya (CHIKV). Londrina city, Paraná, stands out for the number of cases and deaths from dengue. Therefore, this study aimed to verify the density and diversity of mosquitoes present in urban public establishments of Londrina, to analyze their ecological relationships, and to investigate the presence of the DENV, ZIKV, and CHIKV. Ovitraps were installed in outdoor sites in two public establishments in each region of Londrina, while adult culicids were caught indoors with a Nasci aspirator. A total of 5077 eggs were obtained in 77 ovitraps. The South region had the highest infestation while the East had the lowest (Ovitrap Positivity Index: 38% and 25%; Egg Density Index: 67.83 and 19.03, respectively). From eggs, 704 Aedes aegypti females and 71 Aedes albopictus females were obtained, while in the aspiration of adults, 99 A. aegypti and 11 Culex quinquefasciatus were captured, the highest number in the West and the lowest in the North. The DENV-II virus was detected in a pool of 17 A. aegypti females in the West region. The results demonstrate high density of pathogen vector species, mainly A. aegypti, in and around establishments, alerting to the need for constant local entomological surveillance to prevent viral circulation, mainly in crowded places. The presence of A. albopictus around the establishments also alerts to the urbanization of the species and potential participation in the viral circulation, demonstrating the need for constant monitoring.

ABSTRACT

At present, the contradiction between the lack of pediatricians and the increasing demand for pediatric medical services has become more and more prominent. Taking pediatricians as the research object, this paper explored the needs and motivation of professional development of pediatricians in China by referring to a series of excellent foreign research results, so as to improve the professional development of pediatricians, reconstruct the ecology of pediatricians and patients, then improve medical experience, and alleviate the "shortage of pediatricians" and "difficulty in seeing a doctor" in pediatrics. Enhancing the work enthusiasm and professional motivation of pediatricians can not only improve the satisfaction of patients, but also enhance the quality of medical services, so as to promote the growth of the hospital’s own economic and social benefits.

ABSTRACT

Abstract Introduction: Epiphytes (vascular and non-vascular) are one of the most diverse groups in the Neotropics, but despite their importance in the functioning of many ecosystems, much of their taxonomy and ecology is still unknown in the dry forest of Colombia. Objective: To compare the diversity patterns and species composition of vascular and non-vascular epiphytes along tropical dry forest remnants of Cauca Valley, Colombia. Methods: Ten permanent plots (50 x 20 m2) were established in tropical dry forest remnants. The epiphytes were sampled in 40-50 trees per plot. Alpha and gamma diversity were calculated using the richness (q0) and Shannon index (q1) (alpha was estimated as the average for phorophytes). Beta diversity was measured using the Whitaker index. To evaluate the relationship between diversities and environmental variables, GLM analysis was used. Results: We found 50 morphospecies of vascular epiphytes, 77 of bryophytes and 290 of lichens. The 𝛼 and 𝛾 diversity of bryophytes from each remnant was significantly explained by temperature. The abundance of lichens per tree was significantly related with the DBH and tree height of each remnant. The 𝛼 diversity of vascular epiphytes shown can be explained by temperature and precipitation. The 𝛾 diversity was strongly influenced by the beta diversity in bryophytes and lichens. This pattern is because the sites with high disturbance present a lower diversity, as a consequence of a homogenizing effect, that is, a low turnover of species between sampling units. Conclusions: Precipitation and temperature affected the diversity of bryophytes and vascular epiphytes, while it did not show a relationship with the lichen's diversity, for which there is not a high congruence between the diversity and composition of these epiphytes.


Resumen Introducción: Los epífitos (vasculares y no vasculares) son uno de los más diversos grupos de plantas en el Neotrópico, pero a pesar de su importancia para el funcionamiento de varios ecosistemas, existen grandes vacíos en su conocimiento taxonómico y ecológico en el bosque seco de Colombia. Objetivo: Comparar los patrones de diversidad y composición de especies de epífitas vasculares y no vasculares a lo largo de remanentes de bosque seco tropical del Valle del Cauca, Colombia. Métodos: Se establecieron diez parcelas permanentes (50 x 20 m2) en remanentes de bosque seco tropical. Las epífitas se muestrearon en 40-50 árboles por parcela. La diversidad alfa y gamma se calculó utilizando la riqueza (q0) y el índice de Shannon (q1) (alfa se estimó como el promedio para los forófitos). La diversidad beta se midió utilizando el índice de Whitaker. Para evaluar la relación entre diversidades y variables ambientales se utilizó el análisis GLM. Resultados: Se encontraron 50 morfoespecies de epífitas vasculares, 77 de briófitas y 290 de líquenes. La diversidad de 𝛼 y 𝛾 de briófitas de cada remanente fue explicada significativamente por la temperatura. La abundancia de líquenes por árbol se relacionó significativamente con el DAP y la altura del árbol de cada remanente. La diversidad 𝛼 de epífitas vasculares que se muestra puede explicarse por la temperatura y la precipitación. La diversidad 𝛾 estuvo fuertemente influenciada por la diversidad beta en briófitas y líquenes. Este patrón se debe a que los sitios con alta perturbación presentan una menor diversidad, como consecuencia de un efecto homogeneizador, es decir, un bajo recambio de especies entre unidades de muestreo. Conclusiones: La precipitación y la temperatura afectaron la diversidad de briófitas y epífitas vasculares, mientras que no mostró relación con la diversidad de líquenes, por lo que no existe una alta congruencia entre la diversidad y composición de estas epífitas.

ABSTRACT

el texto busca ampliar las fronteras del concepto de "bioética global", centro de la propuesta teórica de Van Rensselaer Potter sobre la "bioética ecológica" en su obra Global Bioethics, de cara a la "ética de la tierra" desarrollada por el ecólogo y ambientalista Aldo Leopold y el análisis de la "ecosofía" planteado por el filósofo y psicoanalista Félix Guattari en Las tres ecologías. Dicha caracterización se plantea con el fin de establecer presupuestos teóricos en torno a las nociones de bioética ecológica y ecosofía en la perspectiva de la bioética global en un renovado intento de ampliación de sus horizontes disciplinares. Se establecen tres momentos para el análisis: inicialmente se caracteriza la ética de la tierra propuesta por Arnold Leopold en su obra A Sand County Almanach. Posteriormente, se analizan los principales aspectos de la "ética ecológica" en la obra Global Bioethics. Finalmente, se destacan varios aspectos de la ecosofía de Félix Guattari que ponen en perspectiva el acento ecológico de la bioética global de Potter y que podrían considerarse como presupuestos divergentes útiles para enriquecer la bioética global en la actualidad.


the text seeks to expand the boundaries of the concept of "global bioethics," the core of Van Rensselaer Potter's theoretical proposal on "ecological bioethics" in his work Global Bioethics, in the face of the "ethics of the Earth" developed by the ecologist and environmentalist Aldo Leopold and the analysis of "ecosophy" raised by the philosopher and psychoanalyst Félix Guattari in The Three Ecologies. This characterization is proposed to establish theoretical assumptions around the notions of ecological bioethics and ecosophy from the perspective of global bioethics in a renewed attempt to broaden its disciplinary horizons. Three moments are established for the analysis: initially, the land ethics proposed by Arnold Leopold in his work A Sand County Almanach is characterized. Subsequently, the main aspects of "ecological ethics" in Global Bioethics are analyzed. Finally, several aspects of Félix Guattari's ecosophy are highlighted that put into perspective the ecological accent of Potter's global bioethics, which could be considered valid divergent presuppositions to enrich global bioethics today.

ABSTRACT

Introduction: Coral-reef communities are considered one of the most biodiverse, but also most threatened, marine ecosystems, and the accelerating loss of habitat over the past decades warrants active intervention. Objective: The present study demonstrates the successful implementation of a low-impact restoration technique in three Central Mexican Pacific degraded coral communities, using a protocol based on natural fragmentation (''fragments of opportunity") of the branching coral Pocillopora spp., considered the most abundant and primary carbonate-producing coral species of the Eastern Tropical Pacific. Methods: The restoration program was implemented in two offshore and one inshore coraline areas. The relationships between seawater temperature and coral survival, growth, and attachment rate were assessed over one year, with 183 fragments monitored each month. Results: The mean coral growth rate was 3.3 ± 0.1 mm mo-1, with annual growth rates in length and width of 39.9 ± 14.2 and 36.5 ± 19.5 mm yr-1, respectively. Self-attachment efficiency was 78 % and the survival rate was high (84 %). The growth rate differed significantly among reefs. Conclusions: Upon monitoring directly fragmented corals over a year, growth rates were deemed high enough to merit active restoration in the region. However, our data show that structural and abiotic differences and seasonal variability must be considered overall in successful long-term coral community restoration initiatives in the eastern Pacific region.


Introducción: Las comunidades de arrecifes de coral se consideran uno de los ecosistemas marinos con mayor biodiversidad, pero también los más amenazados, y la pérdida acelerada de hábitat en las últimas décadas justifica la implementación de una intervención activa. Objetivo: El presente estudio demuestra la implementación exitosa de una técnica de restauración de bajo impacto basada en la fragmentación natural (''fragmentos de oportunidad") del coral ramificado Pocillopora spp., la cual es la especie coralina más abundante y principal productora de carbonato del Pacífico Oriental Tropical. Métodos: El programa de restauración se implementó en dos sitios lejos de la costa y un sitio cercano a la costa, con comunidades coralinas degradadas. Las relaciones entre la temperatura del agua de mar y la supervivencia, el crecimiento y la tasa de adhesión de los corales se evaluaron durante un año con 183 fragmentos monitoreados cada mes. Resultados: La tasa media de crecimiento coralino fue de 3.3 ± 0.1 mm mo-1, con tasas de crecimiento anual en largo y ancho de 39.9 ± 14.2 y 36.5 ± 19.5 mm año-1, respectivamente. La eficiencia de la auto-adherencia fue del 78 % y la tasa de supervivencia fue alta (84 %). La tasa de crecimiento difirió significativamente entre los arrecifes. Conclusiones: Al monitorear directamente los corales fragmentados durante un año, las tasas de crecimiento se consideraron lo suficientemente altas como para merecer una restauración activa en la región. Sin embargo, nuestros datos muestran que las diferencias estructurales y abióticas y la variabilidad estacional deben considerarse en general en las iniciativas exitosas de restauración de comunidades de coral a largo plazo en la región del Pacífico oriental.

ABSTRACT

Introduction: Associated fauna comprises most of the diversity of a coral reef and performs ecological functions essential to the reef's survival. Since Pocillopora corals harbor an important associated fauna, reef restoration efforts are underway in Golfo Dulce, Costa Rica, to preserve them. Objective: To describe changes in cryptofauna and fish communities associated with Pocillopora colonies to better understand the succession of associated fauna following transplantation. Methods: An experimental patch of 30 nursery-grown Pocillopora colonies and a control patch containing no colonies were monitored for 8 months following transplantation in Golfo Dulce. Cryptofauna within each colony and fish within each patch were observed using SCUBA to quantify temporal changes in the abundance, diversity, and community structure of the colonies. Results: The abundance and diversity of cryptofauna increased throughout the experiment. Obligate symbiont decapods were the most abundant. The composition of the community of cryptofauna differed between periods with fish in the genus Scarus as the main contributor to any differences. The increase in abundance and diversity of cryptofauna and fish may reflect coral growth and the corresponding availability of space and environmental complexity in the experimental patch. The composition of the cryptofauna communities was generally consistent with other studies. However, a high density of decapod symbionts could suggest that without other Pocillopora colonies to move to, they may crowd together despite their aggressive tendencies. Conclusions: Pocillopora colonies will experience an increase in symbionts that could positively contribute to the health and survival of the coral following transplantation.


Introducción: La fauna asociada comprende la mayor parte de la diversidad de un arrecife de coral y realiza funciones ecológicas esenciales para la supervivencia del arrecife. Dado que los corales Pocillopora albergan una importante fauna asociada, se están realizando esfuerzos de restauración de arrecifes en Golfo Dulce, Costa Rica, para preservarlos. Objetivo: Describir los cambios en la comunidad de criptofauna y peces asociados a las colonias de Pocillopora para comprender mejor la sucesión de la fauna asociada después del trasplante. Métodos: Un parche experimental de 30 colonias de Pocillopora cultivadas en vivero y un parche de control que no contenía colonias fueron monitoreados durante 8 meses después del trasplante en Golfo Dulce. La criptofauna dentro de cada colonia y los peces dentro de cada parche se observaron usando SCUBA para cuantificar los cambios temporales en la abundancia, diversidad y estructura de la comunidad de las colonias. Resultados: La abundancia y diversidad de criptofauna aumentó a lo largo del experimento. Los decápodos simbiontes obligados fueron los más abundantes. La composición de la comunidad de criptofauna difirió entre períodos con peces del género Scarus como el principal contribuyente a cualquier diferencia. El aumento en la abundancia y diversidad de criptofauna y peces puede reflejar el crecimiento de coral y la correspondiente disponibilidad de espacio y complejidad ambiental en el parche experimental. La composición de las comunidades de criptofauna fue generalmente consistente con otros estudios. Sin embargo, una alta densidad de simbiontes decápodos podría sugerir que, sin otras colonias de Pocillopora a las que trasladarse, pueden amontonarse a pesar de sus tendencias agresivas. Conclusiones: Las colonias de Pocillopora experimentarán un aumento de simbiontes que podrían contribuir positivamente a la salud y supervivencia del coral después del trasplante.

ABSTRACT

Resumo Este ensaio busca analisar os impactos sociossanitários exercidos pelo meio ambiente, incorporando as dinâmicas trazidas pela covid-19 e evidenciando as repercussões da pandemia. O coronavírus atingiu sobretudo países que falharam na prevenção e não estabeleceram medidas de intervenção eficazes e colaborativas. A destruição da natureza se intensificou na pandemia, assim como as ameaças enfrentadas por seus defensores, o que agravou ainda mais a crise. Nesse contexto pode-se destacar os riscos apresentados aos indígenas brasileiros e aos ambientalistas latino-americanos; o surgimento de grupos perigosos; e a implementação de políticas governamentais de efeitos críticos que afetam a preservação ambiental e colocam em risco os modos de vida tradicionais. Assume-se, desse modo, que o planeta enfrenta uma crise sanitária, mas também socioeconômica e ambiental. Para que tal crise heterogênea seja superada, os esforços precisam ser multiformes, envolvendo: cuidados à saúde e aos ecossistemas; diminuição da pobreza global e da desigualdade sanitária; redução de riscos ambientais; proteção dos modos de vida tradicionais; defesa das democracias e dos direitos humanos; fomento de políticas de desenvolvimento sustentável; e cooperação internacional. Tais esforços também incidirão sobre os anos vindouros, minimizando os riscos de novas pandemias e atuando na preservação ambiental.


Abstract This essay analyzes the socio-sanitary impacts exerted by the environment, incorporating the dynamics brought about by the COVID-19 pandemic and unveiling its repercussions. Countries that failed to prevent the virus spread and to established effective and collaborative intervention measures were hit the hardest. Environmental destruction reached new heights in the pandemic, as have the threats faced by its defenders, further aggravating the crisis. In this scenario one can highlight the risks posed to Brazilian Indigenous peoples and Latin American environmentalists; the emergence of dangerous groups; and the implementation of government policies with critical effects on environmental preservation that put traditional ways of life at risk. It is thus recognized that the planet faces not only a health crisis, but also a socioeconomic and environmental one. To overcome such heterogeneous crisis, efforts must be multifaceted, involving: caring for health and ecosystems; eliminating global poverty and sanitary inequality; reducing environmental risks; protecting traditional ways of life; defending democracies and human rights; and fostering sustainable development policies and international cooperation. These efforts will also affect the years to come, minimizing the risks of new pandemics and acting to preserve the environment.

ABSTRACT

RESUMEN Se presenta la entrevista realizada en 1998 a Kerr L. White (1917-2014), traducida al español. White fue un economista, epidemiólogo, estadístico, médico general, sanitarista, muy crítico de la separación entre la investigación, la clínica, la epidemiología, la salud pública y las políticas de salud. Fue uno de los fundadores de la investigación sobre los servicios de atención médica. Su preocupación básica fue la responsabilidad de la sociedad para asignar recursos de atención médica de la manera más apropiada para mejorar la salud de las poblaciones. La producción de White señala críticamente la ausencia de una mirada poblacional en la epidemiología aplicada a servicios y sistemas de salud, y en la evaluación del impacto social y económico de las prácticas, señalando además la deshumanización de los procesos de atención y cuidado. Sus trabajos han sido poco citados en los textos del campo de la salud, por lo que recuperamos su figura con el objetivo de difundir la vigencia de su pensamiento y su obra.


ABSTRACT The interview conducted in 1998 with Kerr L. White (1917-2014) is presented, translated into Spanish. White, an economist, epidemiologist, statistician, general physician, and health advocate, was highly critical of the separation between research, clinical practice, epidemiology, public health, and health policies. He was one of the pioneers in healthcare services research. His primary concern was society's responsibility to allocate healthcare resources in the most appropriate way to improve the health of populations. White's work critically addresses the absence of a population perspective in epidemiology applied to healthcare services and systems, and the lack of evaluation of the social and economic impact of practices. He also highlights the dehumanization of care processes. Despite being undercited in health literature, we reintroduce his figure with the aim of disseminating the relevance of his thoughts and contributions.

ABSTRACT

Resumo: Neste artigo, por meio de revisão bibliográfica, discutimos a ecologia a partir da categoria-padrão de reprodução do capital, destacando a dialética entre valor e valor de uso. Concluímos, com base na TMD, que a categoria-padrão de reprodução do capital permite compreender a ecologia no âmbito da particularidade, evidenciando que a valorização é sempre acompanhada da produção material e que distintos padrões de reprodução do capital impactam desigualmente o meio ambiente e a sociedade.


Abstract: In this article, through a literature review, we discuss ecology based on the standard category of capital reproduction, highlighting the dialectic between value and use-value. We conclude, based on TMD, that the standard category of capital reproduction enables the understanding of ecology within the realm of particularity, demonstrating that valorization is always accompanied by material production and that different patterns of capital reproduction unevenly impact the environment and society.

ABSTRACT

RESUMO: As crises que caracterizam nosso tempo espelham uma crise civilizatória com raízes no monopólio do saber, em que os modos de conhecer desenvolvidos pelo capitalismo científico degradam o ambiente e subjugam saberes construídos na coevolução das culturas com a natureza, os territórios e os meios de vida. A tecnologia e as inovações científicas assumiram papel central na sociedade atual, mediando um sem-número de relações sociais, ambientais e políticas hegemonizadas pelo capitalismo colonial contemporâneo. Neste ensaio, buscamos trazer reflexões sobre as relações entre os campos da energia e da saúde que, além de manifestarem sucessivas crises, vêm mobilizando o imaginário social nos últimos anos por serem regidos por sistemas sociotécnicos que condicionam os modos de vida modernos. As crises energética e sanitária são abordadas com base em suas construções históricas, nas estruturas produtivas que mobilizam, nos modos de vida que criam e nas relações sociais que ordenam. Apontamos para os mecanismos por meio dos quais os circuitos globais do capital exportam externalidades na direção das populações com menor acesso à energia mecânica disponível em seus sistemas sociotécnicos, gerando catástrofes socioambientais, expropriação de terras, perda de biodiversidade, mudanças climáticas, poluição, pobreza, fome e epidemias.


ABSTRACT: The crises that characterize our time mirror a civilizational crisis with roots in the monopoly of knowledge, in which the ways of knowing developed by scientific capitalism degrade the environment and subjugate knowledge built in the co-evolution of cultures with nature, territories and means of life. Technology and scientific innovations have taken a central role in today's society, mediating countless social, environmental and political relations hegemonized by contemporary colonial capitalism. In this essay, we seek to bring reflections on the relationships between the fields of energy and health which, in addition to manifesting successive crises, have been mobilizing the social imagination in recent years as they are governed by socio-technical systems that condition modern ways of life. Energy and health crises are addressed based on their historical constructions, the productive structures they mobilize, the ways of life they create and the social relations they order. We point to the mechanisms by which global circuits of capital export externalities towards populations with less access to mechanical energy available in their socio-technical systems, generating socio-environmental catastrophes, land expropriation, loss of biodiversity, climate change, pollution, poverty, famine and epidemics.


RESUMEN: Las crisis que caracterizan nuestro tiempo reflejan una crisis de civilización con raíces en el monopolio del conocimiento, en la que las formas de conocimiento desarrolladas por el capitalismo científico degradan el medio ambiente y subyugan el conocimiento construido en la coevolución de las culturas con la naturaleza, los territorios y los medios de vida. La tecnología y las innovaciones científicas han asumido un papel central en la sociedad actual, mediando innumerables relaciones sociales, ambientales y políticas hegemonizadas por el capitalismo colonial contemporáneo. En este ensayo buscamos traer reflexiones sobre las relaciones entre los campos de la energía y la salud que, además de manifestar crisis sucesivas, vienen movilizando el imaginario social en los últimos años al estar regidos por sistemas sociotécnicos que condicionan las formas modernas. de vida. Las crisis energética y sanitaria se abordan a partir de sus construcciones históricas, las estructuras productivas que movilizan, los modos de vida que crean y las relaciones sociales que ordenan. Señalamos los mecanismos a través de los cuales los circuitos globales de capital exportan externalidades hacia poblaciones con menor acceso a la energía mecánica disponible en sus sistemas sociotécnicos, generando catástrofes socioambientales, expropiación de tierras, pérdida de biodiversidad, cambio climático, contaminación, pobreza, hambruna y epidemias.

ABSTRACT

Abstract Low biodiversity in urban areas is associated with habitat loss. However, the effects of urbanization on biodiversity should also consider the historical background of land-use, explored herein. Our goal was to evaluate changes in the assemblage of reptiles in an urban habitat over 100 years, aiming to identify which ecological attributes allowed the persistence of species that can be found in the area today. We accessed historical records in scientific collections and carried out fieldwork to access reptile assemblage in an urban green area, in São Paulo, Brazil. Considering land-use changes in the area, we defined three-time intervals between 1901 and 2020. We established species richness for each time interval, categorizing them into three ecological attributes: habitat preference, substrate use, and food habits. We recorded 27 reptile species from 1901 until 2020, 14 resulting from historical data, eight from both historical and fieldwork, and five species exclusively in fieldwork. Amphibians were also sampled during fieldwork, but not used in historical comparison. Reptile's species richness decreased 59% regardless of ecological attributes, and snakes were the group with most species' loss. Fossorial reptiles were the least affected group. We concluded that habitat loss culminated in a species richness decline, and the reptiles that remain until today were likely present since the fragment isolation. Ecological attributes of the remaining taxa include species that use terrestrial substrates and feed on prey commonly found in urban environments.


Resumo A baixa biodiversidade em áreas urbanas está associada à perda de habitat. No entanto, os efeitos da urbanização sobre a biodiversidade também devem considerar o histórico de uso da terra, explorado aqui. Nosso objetivo foi avaliar as mudanças na comunidade de répteis em um habitat urbano ao longo de 100 anos, visando identificar quais atributos ecológicos permitiram a persistência de espécies que podem ser encontradas na área hoje. Acessamos registros históricos em coleções científicas e realizamos trabalho de campo para levantar as espécies de répteis em uma área verde urbana, em São Paulo, Brasil. Considerando as mudanças de uso da terra na área amostrada, definimos três intervalos de tempo entre 1901 e 2020. Estabelecemos a riqueza de espécies para cada intervalo de tempo, categorizando-as em três atributos ecológicos: preferência de habitat, uso de substrato e hábitos alimentares. Registramos 27 espécies de répteis de 1901 até 2020, sendo 14 resultantes de dados históricos, oito de dados históricos e de campo e cinco espécies amostradas exclusivamente de campo. Anfíbios também foram amostrados durante o trabalho de campo, mas não foram usados na comparação histórica. A riqueza de espécies de répteis diminuiu 59% independentemente dos atributos ecológicos, e serpente foi o grupo com maior perda de espécies. Os répteis fossoriais foram o grupo menos afetado. Concluímos que a perda de habitat culminou em um declínio da riqueza de espécies, e os répteis que permanecem até hoje provavelmente estavam presentes desde o isolamento do fragmento. Os atributos ecológicos dos táxons remanescentes incluem espécies que utilizam substratos terrestres e se alimentam de presas comumente encontradas em ambientes urbanos.

ABSTRACT

ABSTRACT Temperature affects the body size of animals, which is an important trait in natural and sexual selection. Insects do not have complex mechanisms of temperature control, thus temperature changes affect their life aspects, from enzymatic reactions to behavior. The amount of fat stored by insects is also influenced by temperature and constitutes a tissue with biosynthetic and metabolic activity, acting as an energy reservoir. We assessed the effect of environmental temperature due to elevation and seasonal temperature variations on body size and condition of two dung beetles species: Canthon rutilans cyanescens and Dichotomius sericeus (Coleoptera: Scarabaeinae). Both species are abundant in southern Brazilian forests, but they differ in habits: the first is a diurnal roller whereas the later is a nocturnal tunneler. Summer months and sites with lower elevations and higher temperatures presented larger C. rutilans cyanescens. A linear relationship exists between body size and soil temperatures, whereas the temperature positively influences the body length. Furthermore, C. rutilans cyanescens from cooler sites had more body fat. Individuals of D. sericeus were also larger in summer months, however, we did not find differences in the proportion of fat or a relation between body size and temperature. Thus, the body size of dung beetle species varies in relation to temporal factors, as both species are larger in summer. More interesting was to observe that the species with a diurnal habit, even though smaller in colder places, has a higher proportion of fat, which indicates an evolutionary response to environmental pressure.

ABSTRACT

RESUMO O objetivo desta nota é colocar em evidência alguns apontamentos para se pensar a educação escolar em tempo de pós-pandemia. As interfaces entre o processo formativo do sujeito e a educação escolar em tempo de pós-pandemia se encontram em um paradoxo: por um lado, a dificuldade na construção, pelo viés democrático, da proposta de ensino da unidade escolar como lugar para se fazer o espaço do comum, na partilha da cultura escolar; por outro lado, a exclusão que se encontra instituída no sistema educacional e que restringe o direito à educação.


ABSTRACT The aim of this article is to highlight some notes to think about school education in post-pandemic times. The interfaces between the subject's formative process and school education in post-pandemic times are in a paradox: on the one hand, the difficulty building, through democratic bias, the proposal of teaching the school unit as a place to make the space of the common, in sharing the school culture; on the other hand, the exclusion that is established in the educational system and that restricts the right to education.


RESUMEN El objetivo de esta nota es poner en evidencia algunos apuntes para pensar en la educación escolar en el tiempo post-pandemia. Las interfaces entre el proceso formativo del sujeto y la educación escolar en tiempo de post-pandemia se encuentran en una paradoja: por un lado, la dificultad de construir, por el sesgo democrático, la propuesta de enseñar la unidad escolar como lugar para hacer el espacio de lo común, compartir la cultura escolar; por otra parte, la exclusión que se ha establecido en el sistema educativo y que limita el derecho a la educación.
