New pseudoscorpion species (Pseudoscorpiones: Hesperolpiidae) from Lima City, Peru

This study describes and illustrates a new species of arachnid, the pseudoscorpion Stenolpium sayrii sp. nov., collected at Pucllana, an archaeological site in the city of Lima, Peru. With this description, the total number of known Stenolpium species worldwide reaches eight, and in Peru specifically, it increases to seven. The discovery of this new species in Peru's most populous city serves as an exemplar highlighting the extensive scope for further research on Peruvian fauna in general, particularly on its arachnids.

En este trabajo, una nueva especie de arácnido, el pseudoscorpión Stenolpium sayrii sp. nov., colectada en Pucllana, sitio arqueológico de la ciudad de Lima, Perú, es descrita e ilustrada. Con esta descripción, el número de especies conocidas de Stenolpium en el mundo asciende a ocho en total y para el Perú a siete. El descubrimiento de esta nueva especie en la ciudad más poblada del Perú es un ejemplo de lo mucho que falta investigar sobre la fauna peruana en general y sobre sus arácnidos en particular.

Cacería para autoconsumo durante la pandemia de COVID-19: el caso de las comunidades Matsigenkas del Parque Nacional del Manu

En este trabajo, se hipotetiza el periodo de aislamiento, la inmovilización y la migración inversa que sucedidos durante la pandemia del COVID-19 (años 2020 y 2021) incrementaron la capacidad de caza de las comunidades Matsigenkas asentadas en el Parque Nacional del Manu (PN Manu). Para esto, evaluamos los cambios en los patrones del volumen de extracción de la caza a través de un monitoreo participativo utilizando el modelo de monitoreo de la intensidad de cacería. Se evidenció que hubo un incremento de la capacidad de caza de las comunidades nativas. Los volúmenes más altos de extracción y el mayor incremento del número de cazadores, esfuerzo y área de cacería se dieron en el periodo 2020 - 2021, cuando las medidas de aislamiento e inmovilización fueron establecidas. Sin embargo, hubo una disminución de los indicadores para la temporada 2021 - 2022, año en que se flexibilizaron las medidas de aislamiento y se dio la reactivación económica, permitiendo que las personas retornaran a sus actividades económicas y educativas fuera del PN Manu. Se debe considerar que los efectos de solo un año de pandemia sobre los medios de subsistencia de las comunidades pudieron afectar la abundancia de la fauna silvestre, donde el mono maquisapa y mono choro (especies vulnerables) tuvieron altos incrementos de extracción. Por otro lado, nuestros resultados indicarían que el buen estado de conservación del PN Manu permitió la provisión de alimentos a las comunidades durante la pandemia. Se recomienda la planificación de programas que mitiguen los efectos negativos de pandemias o eventos semejantes, además se señala la importancia de medir el grado de resiliencia de las principales especies de caza, ya que el incremento de caza también podría tener efectos sobre la seguridad alimentaria de estas comunidades.

In this work, we hypothesize that the period of isolation, immobilization, and reverse migration that occurred during the COVID-19 pandemic (years 2020 and 2021) increased the hunting capacity of the Matsigenka communities settled in Manu National Park (PN Manu). To evaluate this, we assessed changes in hunting volume patterns through participatory monitoring using the hunting intensity monitoring model. It was evident that there was an increase in the hunting capacity of Matsigenka communities. The highest extraction volumes and the greatest increase in the number of hunters, hunting effort, and hunting area occurred in the 2020-2021 period, the year in which isolation and immobilization measures were established. However, there was a decrease in the indicators for the 2021-2022 period, the year in which isolation measures were relaxed and economic reactivation occurred, allowing people to return to their economic and educational activities outside PN Manu. It should be considered that the effects of only one year of the pandemic on the livelihoods of the communities could have affected the abundance of wildlife, with vulnerable species such as maquisapa monkeys and choro monkeys experiencing high extraction rates. On the other hand, our results indicate that the good conservation status of PN Manu provided food provisions for the communities during the pandemic. Planning programs to mitigate the negative effects of pandemics or similar events is recommended, and the importance of measuring the resilience of key hunting species is emphasized, as increased hunting could also have effects on the food security of these communities.

Molecular detection of Leptospira spp. in small wild rodents from rural areas of São Paulo State, Brazil

ABSTRACT Background: Leptospirosis represents a One Health issue, affecting humans and animals. This study investigated pathogenic leptospires in small wild rodents in São Paulo, Brazil. Methods: Kidney samples from 164 rodents underwent qPCR testing, targeting pathogenic Leptospira spp. Results: Thirty-five animals (21.34%) tested positive, including five rodent species: Akodon montensis (2/21; 9.5%), Necromys lasiurus (1/4; 25%), Oligoryzomys nigripes (24/92; 26.1%), Oligoryzomys flavescens (5/26; 19.2%), and Sooretamys angouya (3/14; 21.4%). Botucatu municipality exhibited the highest prevalence, with 42.5% (20/47) of the animals testing positive. Conclusions: The presence of Leptospira spp. in wild rodents suggests they may be chronic carriers, contaminating the environment.

Metagenomic Analysis of Environmental Samples from Wildlife Rescue Station at Poyang Lake, China / 生物医学与环境科学（英文）

OBJECTIVE@#To improve the understanding of the virome and bacterial microbiome in the wildlife rescue station of Poyang Lake, China.@*METHODS@#Ten smear samples were collected in March 2019. Metagenomic sequencing was performed to delineate bacterial and viral diversity. Taxonomic analysis was performed using the Kraken2 and Bracken methods. A maximum-likelihood tree was constructed based on the RNA-dependent RNA polymerase (RdRp) region of picornavirus.@*RESULTS@#We identified 363 bacterial and 6 viral families. A significant difference in microbial and viral abundance was found between samples S01-S09 and S10. In S01-S09, members of Flavobacteriia and Gammaproteobacteria were the most prevalent, while in S10, the most prevalent bacteria class was Actinomycetia. Among S01-S09, members of Myoviridae and Herelleviridae were the most prevalent, while the dominant virus family of S10 was Picornaviridae. The full genome of the pigeon mesivirus-like virus (NC-BM-233) was recovered from S10 and contained an open reading frame of 8,124 nt. It showed the best hit to the pigeon mesivirus 2 polyprotein, with 84.10% amino acid identity. Phylogenetic analysis showed that RdRp clustered into Megrivirus B.@*CONCLUSION@#This study provides an initial assessment of the bacteria and viruses in the cage-smeared samples, broadens our knowledge of viral and bacterial diversity, and is a way to discover potential pathogens in wild birds.

Feral dogs in Chitral gol national park, Pakistan: a potential threat to the future of threatened Kashmir Markhor (Capra falconeri cashmiriensis) / Cães ferozes no parque nacional Chitral gol, Paquistão: uma ameaça potencial para o futuro do Markhor da Caxemira ameaçado (Capra falconeri cashmiriensis)

Abstract Feral dogs are well-organized hunters of ungulates in many parts of the world, causing great damage to wildlife populations and ultimately to the ecosystem. In Pakistan, the impacts of feral dogs on the wildlife have not been documented yet. In a period of fifteen years (2006-2020), feral dogs have killed hundreds of threatened markhor in Chitral gol national park (CGNP), Pakistan. Despite direct predation other impacts including disturbance and competition with other natural predators, could compromise conservation and management efforts. The population of feral dogs seems to have been increased with the increase of dumping sites by communities. Our findings suggest that there are pressing needs of controlling the feral dogs population and eradicating them from the core zone of CGNP and surrounding buffer communities. Conventional culling of dogs should be coupled with modern techniques like castration and sterilization. Communities should be educated regarding the clean environment, proper disposal of home wastes and, biodiversity conservation.

Resumo Os cães ferozes são caçadores bem organizados de ungulados em muitas partes do mundo, causando grandes danos à população de animais selvagens e, em última instância, ao ecossistema. No Paquistão, os impactos dos cães selvagens na vida selvagem ainda não foram documentados. Em um período de 15 anos (2006-2020), cães selvagens mataram centenas de markhor ameaçados no parque nacional Chitral gol (CGNP), Paquistão. Apesar da predação direta, outros impactos, incluindo distúrbios e competições com outros predadores naturais podem comprometer os esforços de conservação e manejo. A população de cães selvagens parece ter aumentado com o aumento dos locais de despejo pelas comunidades. Nossas descobertas sugerem que há necessidades urgentes para controlar a população de cães selvagens e erradicá-los da zona central do CGNP e das comunidades-tampão vizinhas. O abate convencional de cães deve ser combinado com técnicas modernas como castração e esterilização. As comunidades devem ser educadas sobre o meio ambiente limpo, o descarte adequado de resíduos domésticos e a conservação da biodiversidade.

India's Foreign Policy On Environmental Issues: Challenges And Wayforward

Not so long ago, many believed that the pursuit of clean air, clean water, and healthy forests was a worthy goal, but not part of our national security. Today environmental issues are part of the mainstream of Indian foreign policy. Environmental policy is aimed at balancing environmental protection and the conservation of natural resources with other policy goals, such as affordable energy as well as economic growth and employment. In the Directive Principles of State Policy, Article 48 says "the state shall endeavor to protect and improve the environment and to safeguard the forests and wildlife of the country"; Article 51-A states that "it shall be the duty of every citizen of India to protect and improve the natural environment including forests, lakes, rivers and wildlife and to have compassion for living creatures." At the international level, environmental protection is embedded in wider policy concerns and is being woven into broader foreign policy strategy of climate policy, while domestically; it is being shaped to serve national and sub-national development interests. India is emerging as a key player in climate negotiations, while at the national and sub-national levels; the environmental protection policy scene is becoming more active and more determined. It is essential to unravel this complex landscape if we are to understand why policy looks the way it does, and the extent to which India might contribute to a future international framework for tackling environmental degradation as well as how international parties might cooperate with and support India's domestic efforts.

Diversidad y amenazas de los mamíferos mayores en los bosques montanos de Huánuco, Perú / Diversity and threats of larger mammals in montane forests of Huánuco, Peru

Resumen En este trabajo los mamíferos mayores que habitan en los bosques montanos del departamento de Huánuco son estudiados para determinar la diversidad de especies y el estado actual de sus poblaciones. Se realizaron censos por transecto lineal y entrevistas entre los años 2014 y 2015, en seis sitios de muestreo correspondientes a cinco provincias. De los censos y exploraciones nocturnas se obtuvieron 439 registros pertenecientes a 37 especies; de estas, 4 son endémicas de Perú y 9 se encuentran en alguna categoría de conservación de la Legislación peruana. Los órdenes más representativos correspondieron a los carnívoros y primates con 11 y 10 especies, respectivamente, mientras que los avistamientos más frecuentes fueron de Tremarctos ornatus (43 registros), Nasua nasua (34 registros) y Cuniculus paca (32 registros). Los Índices de diversidad de Shannon-Wiener y de Simpson indican a Miraflores como el sitio de muestreo con más alta diversidad (H'=3.11, 1-D=0.95). La principal amenaza para los mamíferos mayores y otros componentes de la fauna mayor es la deforestación; no obstante, la presencia de especies indicadoras de la comunidad primaria de fauna como Tremarctos ornatus, Lagothrix flavicauda y otros primates, nos indican que todavía existen fragmentos de bosque primario relativamente extensos, en particular entre los ríos Chontayacu y Crisnejas en la provincia de Marañón y entre los ríos Oso mayo y Blanco en la provincia de Puerto Inca, por lo que deben ser tomados en cuenta para su conservación.

Abstract In this work, the larger mammals that inhabit the montane forests of the department of Huánuco are studied to determine the diversity of species and the status of their populations. Linear transect censuses and interviews were conducted between 2014 and 2015 on six sampling sites corresponding to five provinces. 439 records belonging to 37 species were obtained from the censuses and nocturnal explorations. Of these species, 4 are endemic to Peru and 9 are in some conservation category of Peruvian legislation. The most representative orders corresponded to carnivores and primates with 11 and 10 species, respectively, while the most frequent sightings were of Tremarctos ornatus (43 records), Nasua nasua (34 records) and Cuniculus paca (32 records). The Shannon-Wiener and Simpson Diversity Indices indicate Miraflores as the sampling site with the highest diversity (H'=3.11, 1-D=0.95). The main threat to larger mammals and other components of the larger fauna is deforestation; however, the presence of indicator species of the primary fauna community such as Tremarctos ornatus, Lagothrix flavicauda and others primates, indicate that there are still relatively extensive fragments of primary forest, particularly between the Chontayacu and Crisnejas rivers in the province of Marañón and between the Oso mayo and Blanco rivers in the province of Puerto Inca, so they must be taken into account for their conservation.

Biodiversity Management and Research in Multifunctional Landscapes / Gestão e pesquisa da biodiversidade em paisagens multifuncionais

Abstract: Despite their negative environmental impacts, human-modified environments such as agricultural and urban landscapes can have a relevant role on biodiversity conservation as complements of protected areas. Such anthropized landscapes may have endangered, valuable, and nuisance species, although most of them do not fit in any of these categories. Therefore, in such environments we must deal with the same decision-making process concerning the same possible interventions proposed by Caughley (1994) to wildlife management, which are related to biological conservation, sustainable use, control/coexistence, and monitoring. Such decision-making process should be based on good science and good governance. On such context, the first step should be to implement multifunctional landscapes, which keep their primary mission of human use, but incorporate a second but fundamental mission of biological conservation. In this study we present a summary of the research carried out at the Biota Program of Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP) in this field since the late 1990's and propose priorities for biodiversity research and governance in multifunctional landscapes for the near future.

Resumo Apesar de seus impactos ambientais negativos, ambientes modificados pelo homem, como paisagens agrícolas e urbanas, podem ter um papel relevante na conservação da biodiversidade como complementos de áreas protegidas. Tais paisagens antropizadas podem ter espécies ameaçadas, valiosas e incômodas, embora a maioria delas não se enquadre em nenhuma dessas categorias. Portanto, em tais ambientes devemos lidar com o mesmo processo de tomada de decisão sobre as mesmas possíveis intervenções propostas por Caughley (1994) para o manejo da vida selvagem, que estão relacionadas à conservação biológica, uso sustentável, controle/coexistência e monitoramento. Esse processo de tomada de decisão deve ser baseado em boa ciência e boa governança. Neste contexto, o primeiro passo deverá ser a implementação de paisagens multifuncionais, que mantenham a sua missão primordial de uso humano, mas que incorporem uma segunda, mas fundamental missão de conservação biológica. Neste estudo apresentamos um resumo das pesquisas realizadas no Programa Biota da Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP) neste campo desde o final da década de 1990 e propomos prioridades para pesquisa e governança da biodiversidade em paisagens multifuncionais para o futuro próximo.

Potentially harmful materials in the feces of wild ring-tailed coatis (Nasua nasua) and health implications / Materiais potencialmente nocivos encontrados nas fezes de quatis (Nasua nasua) selvagens e implicações para a saúde

In ecological parks, the proximity to tourist activities facilitates the exploration of garbage by coatis, with possible serious consequences for the animals health . We described the contents of wild coatis feces from three ecological parks. After analyzing 62 samples, fragments of plants and animals were identified in all feces. In the feces of two parks, seeds were present between 36.4% and 48.6% of the samples. Arthropod fragments were identified in 100% of the samples from two parks, but only 87.3% in a third park. Scales, bones or bird feathers were present in some samples. Undigested material of industrial origin was detected in 34.3% to 54.5% of the samples, such as fragments of paper, string, plastic, aluminum, latex and glass. Results are in line with other studies on the diet of wild coatis, but the intake of foreign bodies, potentially harmful to health, is described for the first time. Clinical problems resulting from ingesting waste can be dental fractures, mucosal erosions, intestinal perforation, peritonitis, impaction, diarrhea, weight loss, intoxication and infections. Coatis in the three parks are at risk of health, and actions are needed to avoid clinical and potentially fatal problems. Four actions are recommended to avoid ingesting foreign bodies: increasing the environmental education of visitors; improving the storage of waste generated in parks; periodically monitor the health of coatis, in order to make interventions when possible; make a permanent program to study the ecology of species in the three parks.

Em parques ecológicos, a proximidade com atividades turísticas facilita a exploração do lixo por quatis (Nasua nasua), com possíveis consequências graves para saúde dos animais. Descrevemos o conteúdo de fezes de quatis selvagens de três parques ecológicos. Após análise de 62 amostras, fragmentos de plantas e animais foram identificados em todas as fezes. Nas fezes de dois parques, as sementes estiveram presentes entre 36,4% e 48,6% das amostras. Foram identificados fragmentos de artrópodes em 100% das amostras de dois parques, mas apenas 87,3% em um terceiro parque. Escamas, ossos ou penas de pássaros estavam presentes em algumas amostras. Detectou-se material não digerido de origem industrial em 34,3% a 54,5% das amostras, como fragmentos de papel, barbante, plástico, alumínio, látex e vidro. Os resultados estão de acordo com outros estudos sobre a dieta de quatis selvagens, mas a ingestão de corpos estranhos, potencialmente prejudicial à saúde, é descrito pela primeira vez. Os problemas clínicos decorrentes da ingestão de lixo podem ser fraturas dentais, erosões de mucosas, perfuração intestinal, peritonite, impactação, diarreia, emagrecimento, intoxicação e infecções. Os quatis nos três parques estão com a saúde em risco, sendo necessárias ações para evitar problemas clínicos e potencialmente fatais. Quatro ações são recomendadas para evitar a ingestão de corpos estranhos: aumentar a educação ambiental dos visitantes; melhorar o armazenamento dos resíduos gerados nos parques; monitorar periodicamente a saúde dos quatis, de forma a fazer intervenções quando possível; fazer um programa permanente de estudo da ecologia das espécies nos três parques.

First description of sarcoptic mange in a wild coati (Nasua narica), in Ecuador, and cooccurrence of canine distemper virus / Primeira descrição da sarna sarcóptica em um coati selvagem (Nasua narica), no Equador, e coocorrência do vírus distemper canino

Abstract We present a case of Sarcoptes and canine distemper virus (CDV) infection in a white-nosed coati (Nasua narica) that was trapped in the dry tropical forest of Cerro Blanco reserve, located in the coastal region of Ecuador. Sarcoptic mange is a highly contagious and zoonotic disease with worldwide distribution that causes epidemics. Mange is produced by Sarcoptes mites that causes severe epidermal damage. Secondary infections and physiological constrictions without treatment can lead to death of the host. In addition, cooccurrence of canine distemper virus was detected via iiRT-PCR from serum samples. Physical analyses showed that 90% of the skin was affected by severe alopecia due to the sarcoptic mange infection. The presence of mites and histopathological analyses confirmed the diagnosis of infection. This coati was taken to a veterinary clinic and was fed every day, but it died after four days. This is the first report of sarcoptic mange and the first report of CDV in white-nosed coatis in South America. Further studies are needed in this region, to seek out other suspected cases, given the high capacity for disease transmission. Preventive actions to avoid epidemic and zoonotic episodes are needed.

Resumo Apresentamos um caso de Sarcoptes e infecção pelo vírus da cinomose canina (CDV) em um quati-do-nariz-branco (Nasua narica) que ficou preso na floresta tropical seca da reserva de Cerro Blanco, localizada na região costeira do Equador. A sarna sarcóptica é uma doença altamente contagiosa e zoonótica de distribuição mundial que causa epidemias. A sarna é produzida por ácaro do gênero Sarcoptes que causa graves danos epidérmicos. Infecções secundárias e constrições fisiológicas sem tratamento podem levar à morte do organismo. Além disso, a coocorrência do vírus da cinomose canina foi detectada, via iiRT-PCR, a partir de amostras de soro. As análises físicas mostraram que 90% da pele estava afetada por alopecia severa devido à infecção pelo ácaro da sarna sarcóptica. A presença de ácaros e análises histopatológicas confirmaram o diagnóstico de infecção. Esse quati foi levado a uma clínica veterinária e foi alimentado todos os dias, mas morreu após quatro dias. Esse é o primeiro relato de sarna sarcóptica e o primeiro relato de CDV em quatis-de-nariz-branco na América do Sul. São necessários mais estudos nessa região, para buscar outros casos suspeitos, dada a alta capacidade de transmissão da doença. Ações preventivas para evitar episódios epidêmicos e zoonóticos, são necessárias.

Blastocystis in captivated and free-ranging wild animals worldwide: a review

@#Blastocystis is the most prevalent eukaryotic gastrointestinal symbiont found in humans and animals worldwide. Increased human infection rates are associated with raising concerns about the involvement of the parasite in public health. Over the last decade, the number of linked epidemiology studies has been prudently grown. Microscopy has been used to detect the presence of protozoan and the advent of molecular techniques has made detection easier. However, due to its limited host specificity and zoonotic potential, animals, either livestock or wildlife animals, may serve as a potential reservoir for Blastocystis infection transmission. The approach utilised in this study aided in understanding the distribution and prevalence of Blastocystis in animals, particularly captivated and free-ranging wild animals worldwide due to increased interest. This review will help comprehend the epidemiological aspects, demographic, subtypes, and the zoonotic potential of Blastocystis in wildlife and captive animals.

Posibles impactos de la carretera Iquitos-Saramiriza sobre la biodiversidad de Loreto, Perú / Possible impacts of the Iquitos-Saramiriza highway on the biodiversity of Loreto, Peru

Resumen La construcción de la carretera Iquitos-Saramiriza proyectada en el departamento de Loreto plantea amenazas sobre la fauna y flora de una zona altamente biodiversa y poco alterada. Aquí, resumimos dichas amenazas en tres puntos: 1) impactos probables, identificados a través de revisión de literatura, 2) estimación de la deforestación, realizada por comparación con otras carreteras amazónicas peruanas y 3) especies más probablemente impactadas. La lista de impactos probables incluyó fragmentación de hábitat, deterioro ambiental, atropellos, dispersión de patógenos, especies invasoras, deforestación, caminos no oficiales y cacería. Estos impactos podrían afectar a unas 3961 especies de plantas y 1595 de vertebrados. La deforestación, en el transcurso de las tres próximas décadas, podría llegar a ser entre 1128 y 3200 km², lo que equivale a más del 80% de la deforestación que ha sufrido Loreto en los últimos 20 años. La fragmentación podría afectar principalmente a unas 83 especies arborícolas y ampliarse hasta la totalidad de fauna y flora en áreas con mayor deforestación. Los atropellos impactarían principalmente a unas 287 especies de animales terrestres, mientras la cacería podría dirigirse hacia unas 31 especies principales. Para 14 especies de vertebrados, la carretera corta completamente su distribución conocida, pudiendo generar poblaciones con poco o nulo intercambio genético. En base a los posibles impactos proyectados, proponemos acciones de mitigación, incluyendo el remplazo de un tramo por transporte fluvial, creación de áreas de protección estricta, instalación de pasos de fauna y la consideración de impactos indirectos en el EIA correspondiente y en otros instrumentos ambientales.

Fauna silvestre con valor de uso en la Reserva de la Biosfera Sierra de Huautla, Morelos, México / Wild fauna with use value in the Biosphere Reserve Sierra de Huautla, Morelos, Mexico

Resumen El objetivo de este trabajo fue sistematizar las especies apropiadas, formas de apropiación y valores de uso asignados a la fauna silvestre en comunidades de la Reserva de la Biosfera Sierra de Huautla, México, mediante un análisis documental y trabajo de campo. Se registraron 46 especies con valor de uso pertenecientes a 31 familias. La clase con mayor número de especies apropiadas son las aves (42.5%), seguidas de los mamíferos (34%). El 64% de las especies se apropian con fines alimentarios y el 38.3% se utilizan para el tratamiento de enfermedades en la medicina tradicional. Otros usos son adornos, amuletos, elaboración de herramientas y como animal de compañía. La apropiación de fauna silvestre se realiza por medio de la cacería, la recolección y la pesca. Las armas de fuego como la escopeta es el principal instrumento para la cacería. También se utilizan perros, machetes, resorteras, tarrayas, anzuelos, nudos corredizos y se capturan manualmente. La apropiación puede ser una actividad oportunista u organizada por medio de las arreadas, espiadas, lampareadas, campeadas, acorralamiento y recolección manual. La apropiación de fauna silvestre es una actividad culturalmente arraigada en las comunidades de la reserva. Sin embargo, el análisis de la relación sociedad-fauna en la región es limitado, por lo que es necesario generar información que promueva el manejo sostenible del recurso faunístico.

Abstract The aims of this paper were the systematization of appropriated species, appropriation forms and assigned use values of wildlife species in the Biosphere Reserve of the Sierra de Huautla, Mexico, by means of documentary analysis and field work. We recorded 46 species with use value pertaining to 31 families. Birds accounted for the highest number of appropriated species (42.5%), followed by mammals (34%). Of the total species, 64% are appropriated for alimentary purposes and are used in the treatment of diseases in traditional medicine. Others are used as ornaments, talismans, in tool manufacture and as pet animals. Wildlife appropriation is achieved by hunting, collection and fishing. Fire arms such as shotguns are the main instrument used in hunting. Dogs, machetes, slingshots, nets, hooks, slipknots, are also used, or they are captured by hand. Appropriation can be an opportunistic or organized activity by means of "arreadas" (herding), "espiadas" (opportunistic observation), "lampareadas" (spotlighting), "campeadas" (scouring), "acorralamiento" (cornering) and manual collection. Wildlife appropriation is a culturally rooted activity in the reserve communities. Nevertheless, the analysis of the relationship society-fauna in the region is limited and this is why the generation of information that may enable a sustainable management of the faunistic resource is necessary.

Effectiveness of aerial wildlife crossings: Do wildlife use rope bridges more than hazardous structures to cross roads? / Eficacia de los pasos aéreos sobre carretera: ¿Cruza la fauna más por puentes de cuerda que por otras estructuras peligrosas?

Abstract Introduction: Although wildlife crossing structures have proven successful at reducing wildlife-vehicle collisions and linking fragmented habitat, their ability to prevent electrocutions of arboreal wildlife has not been closely examined. Objective: To evaluate the effectiveness of aerial rope bridges in restoring habitat connectivity for arboreal species in Manuel Antonio, Costa Rica, while preventing electrocutions by determining 1) what species are using the rope bridges and 2) whether wildlife prefer to use rope bridges instead of other hazardous structures that cross the roads (such as telephone cables, which are often in close proximity to electric wires). Methods: From January to May 2016, nine rope bridges along the highly-trafficked main road that extends from Quepos to Manuel Antonio, Costa Rica, were monitored using camera traps, and ten rope bridges were observed directly along a paved side road off the main road. Results: A total of 11 species were seen using the bridges, and 1 540 crossings were witnessed via camera traps and observations (1 234 via camera traps, 306 during observations). Results from a paired t-test showed no significant difference in the average number of individuals crossing the road via rope bridges versus telephone cables (t(8) = 1.027, P = 0.334). Conclusions: Rope bridges are used by a variety of arboreal wildlife species with a high degree of frequency; however, due to the equally high usage of telephone cables by arboreal wildlife, they are insufficient to prevent wildlife electrocutions on their own. Rope bridges should be installed in tandem with other methods to prevent electrocutions, such as insulating electric wires, to facilitate the safe passage of wildlife over roads.

Resumen Introducción: Aunque los pasos de fauna han demostrado ser exitosos para reducir las colisiones entre vehículos y vida silvestre y vincular el hábitat fragmentado, su capacidad para prevenir electrocuciones de la vida silvestre arbórea no se ha examinado a fondo. Objetivo: Evaluar la efectividad de los puentes aéreos de cuerdas para restaurar la conectividad del hábitat de las especies arbóreas en Manuel Antonio, Costa Rica y al mismo tiempo prevenir las electrocuciones al determinar 1) qué especies están usando los puentes de cuerda y 2) si la vida silvestre prefiere usar puentes de cuerda en lugar de otras estructuras peligrosas que cruzan las carreteras (como cables telefónicos, que frecuentemente están muy cerca de cables eléctricos). Métodos: De enero a mayo de 2016, se monitorearon nueve puentes de cuerda a lo largo de la carretera principal altamente transitada que se extiende desde Quepos a Manuel Antonio, Costa Rica, utilizando cámaras trampa y la observación directa en diez puentes de cuerda a lo largo de una carretera pavimentada más pequeña fuera de la carretera principal. Resultados: Se observaron un total de 11 especies utilizando los puentes y se presenciaron 1 540 cruces mediante cámaras trampa y observaciones (1 234 mediante cámaras trampa, 306 durante las observaciones). Los resultados de una prueba t pareada no mostraron diferencias significativas en el número promedio de individuos que cruzan la carretera a través de puentes de cuerda versus cables telefónicos, t (8) = 1.027, P = 0.334. Conclusiones: Los puentes de cuerdas son utilizados por una variedad de especies de vida silvestre arbóreas con un alto grado de frecuencia; sin embargo, debido al uso igualmente elevado de cables telefónicos por parte de la vida silvestre arbórea, se considera que son insuficientes para prevenir las electrocuciones de la vida silvestre por sí solas. Los puentes de cuerda deben instalarse junto con otros métodos para evitar electrocuciones, como cables eléctricos aislados, para facilitar el paso seguro de la vida silvestre por las carreteras.

First report of pathogenic Leptospira spp. in Tadaridabrasiliensis bats (family Molossidae) and Eptesicus furinalis (family Vespertilionidae) of Argentina. New host species in this country? / Primer reporte de Leptospira spp. patógena en murciélagos Tadaridabrasiliensis (familia: Molossidae) y Eptesicusfurinalis (familia: Vespertilionidae) en Argentina. ¿Nuevas especies hospedadoras en el país?

ABSTRACT Leptospirosis is an endemic disease caused byLeptospiraspp., a bacterium that affects animals and humans. In recent years, the number of reports of leptospirosis in wild animals has increased, which highlights the need to study the infectious agents in these animals. In this study, a duplex PCR for the detection of leptospiral DNA was performed on 50 kidney samples from bats, and a MAT (Microscopic Agglutination Test) for serological detection of anti-leptospiral antibodies was applied to 47 serum samples from bats from different regions of Buenos Aires Province, Argentina. DNA was extracted using Chelex-100 and duplex PCR was performed by targeting the detection of genessecYandflaB, of pathogenicLeptospiraspp. Of the 50 kidney samples, 3 were positive forEumopssp. andTadaridabrasiliensisby duplex PCR. Of the 47 serum samples, 12 were positive for different serovars:Leptospira interrogansserovars Icterohaemorrhagiae, Cynopteri and Bataviae, andLeptospira borgpeterseniiserovar Ballum. This is the first report of the detection of pathogenic leptospires by serology in bats belonging to theT. brasiliensisandEptesicus furinalisspecies in Argentina. In addition, this is the first report of the detection of pathogenic leptospiral DNA by PCR inT. brasiliensisspecies. The detection ofLeptospiraspp. in these wild animals shows that they may play an important role as wildlife reservoirs of leptospires.

RESUMEN La leptospirosis es una enfermedad endémica causada porLeptospiraspp., una bacteria que afecta a animales y a humanos. En los últimos años, el número de reportes de leptospirosis en animales silvestres ha aumentado, lo que resalta la necesidad de analizar los agentes infecciosos en estos animales. En este estudio, se aplicó una reacción en cadena de la polimerasa (PCR) dúplex para la identificación del ADN leptospiral en 50 muestras de riñones de murciélagos y la prueba de aglutinación microscópica (MAT) para la detección serológica de anticuerpos antileptospira en 47 muestras de suero de murciélagos de diferentes regiones de la provincia de Buenos Aires, Argentina. El ADN fue extraído usando Chelex-100 y la PCR dúplex estuvo dirigida a la detección de los genessecYyflaBdeLeptospiraspp. patógena. De las 50 muestras de riñón, tres resultaron positivas por PCR dúplex paraEumopssp. yTadaridabrasiliensis. De las 47 muestras de suero, 12 fueron positivas a diferentes serovares:LeptospirainterrogansserovaresIcterohaemorrhagiae, Cynopteri y Bataviae, yLeptospiraborgpeterseniiserovarBallum. Este es el primer reporte de detección de leptospiras patógenas por serología en murciélagos pertenecientes a las especiesT. brasiliensisyEptesicusfurinalisen Argentina. Además, también es el primero en la localización de ADN leptospiral por PCR en la especieT. brasiliensis.La identificación deLeptospiraspp. en estos animales silvestres muestra que pueden desempeñar un papel importante como reservorios de leptospiras en la fauna silvestre.

Field blood preservation and DNA extraction from wild mammals: methods and key factors for biodiversity studies / Preservación en campo y extracción de ADN en sangre de mamíferos silvestres: métodos y factores claves para estudios de biodiversidad

ABSTRACT Studies on public health and wild mammal biodiversity include a genetic component. For blood samples, there must be optimal sample collection conditions since these can affect DNA preservation and extraction. This study evaluated the use of liquid and dry DNA preservation methods and commercial and non-commercial DNA extraction methods on field-collected blood samples. For this, 264 total blood samples were collected from wild mammals. A first group of samples was preserved in guanidine hydrochloride (GuHCl) and DNA was extracted using six commercial kits: Bioline, Norgen, Invitrogen, Promega, and Qiagen, in addition to phenol-chloroform isoamyl alcohol (PC) and guanidine thiocyanate (GIT). Another group of samples was preserved in Whatman® FTA® cards and DNA was extracted with PC and GIT. The extractions with GIT and PC showed the highest values (ng/µL) and variation in DNA concentration, while the commercial kit showed low variation. Sample preservation in Whatman® FTA® cards provided low variation and quantity of the extracted DNA compared with the use of GuHCl. Concerning DNA quality, the commercial kits yielded higher purity, while GIT and PC-based protocols provided highly variable results. Furthermore, the use of GIT and PC yielded a higher amount of DNA, yet, of variable quality. Overall, extraction based on commercial kits and Whatman® FTA® preservation allowed obtaining more standardized DNA qualities and quantities.

RESUMEN Los estudios sobre salud pública y biodiversidad de mamíferos silvestres incluyen un componente genético. Para las muestras de sangre, se debe tener condiciones óptimas de colección, ya que pueden afectar la preservación y la extracción del ADN. Este estudio evaluó el uso de métodos de preservación de ADN líquido y seco y métodos de extracción de ADN comerciales y no comerciales, en muestras de sangre, recolectadas en campo. Para ello, se recogieron 264 muestras de sangre totales de mamíferos salvajes. Se preservó un primer grupo de muestras en clorhidrato de guanidina (GuHCl) y se extrajo el ADN, utilizando seis kits comerciales: Bioline, Norgen, Invitrogen, Promega y Qiagen, además de dos protocolos no comerciales: fenol-cloroformo isoamil alcohol (PC) y guanidina tiocianato (GIT). Otro grupo de muestras, se preservó en tarjetas Whatman® FTA® y se extrajo el ADN, con PC y GIT. Las extracciones con GIT y PC mostraron los valores y variaciones más altas en la concentración de ADN (ng/µL), mientras que el kit comercial mostró una baja variación. La preservación de la muestra en tarjetas Whatman® FTA® proporcionó una baja variación y cantidad de ADN extraído, en comparación con el uso de GuHCl. En cuanto a la calidad del ADN, los kits comerciales produjeron una mayor pureza (A260/280), mientras que los protocolos basados en GIT y PC proporcionaron resultados muy variables. Además, el uso de GIT y PC originó una mayor cantidad de ADN, pero de calidad variable. En general, la extracción basada en kits comerciales y la conservación Whatman® FTA® permitió obtener calidades y cantidades de ADN más estandarizadas.

The geographic bias of mammal studies: a comparison of a half a century of research on Palearctic and Neotropical mammals / El sesgo geográfico en el estudio de los mamíferos: comparación de medio siglo de investigación sobre mamíferos paleárticos y neotropicales

Abstract Introduction: There are no studies that specifically compare research output of Palearctic and Neotropical mammalogy; such comparison would be useful for informed decisions in conservation and management. Objective: To compare the scientific documents and citations about Palearctic and Neotropical mammals over half a century. Methods: We compared 50 years (1970-2019) of documents on 60 medium and large-sized (heavier than 1 kg) mammal species, in Scopus and the Web of Science (WoS) Core Collection, considering number of documents and four citation indicators at the species level (h-index, citation rate, total citations, and citations per year). Results: We retrieved 13 274 documents in Scopus and 12 913 in WoS. We found that Palearctic mammals have 3.77 times more documents than Neotropical species in Scopus (3.91 times in WoS), and that the documents recorded 5.95 more total citations in Scopus (6.93 times more in WoS). Palearctic documents also record more yearly citations and a higher h-index in both Scopus and WoS. Scopus retrieved more articles for Neotropical species (2 782 vs. 2 631 in WoS) and had more citations (28 120 vs. 24 977 in WoS); differences for the citation indicators between regions were marker in WoS. The h-index and total citations are greatly affected by how many studies are published, i.e. the region with more production is the one with higher values. The Neotropical articles showed a greater growth rate in the last decade, decreasing the gap between both regions. Conclusion: There is a regional bias in WoS and Scopus, which retrieve more articles and citations about Palearctic mammals than about Neotropical mammals; this bias is worse in WoS and means that an urgent increase in indexed research about Neotropical species is needed to be on par with Palearctic research.

Resumen Introducción: No existen estudios que comparen, específicamente, la investigación de la mastozoología paleártica con la neotropical; pero tales comparaciones serían útiles para tomar decisiones informadas en conservación y manejo. Objetivo: Comparar los documentos científicos sobre mamíferos paleárticos y neotropicales, y su impacto en citas, durante medio siglo. Métodos: Comparamos 50 años (1970-2019) de documentos sobre 60 especies de mamíferos de tamaño mediano y grande (más de 1 kg), en Scopus y la colección principal del Web of Science (WoS), considerando el número de documentos y cuatro indicadores de citas a nivel de especie (índice h, tasa de citas, total de citas y citas por año). Resultados: Recuperamos 13 274 documentos en Scopus y 12 913 en WoS, y encontramos que los mamíferos paleárticos tienen 3.77 veces más documentos que las especies neotropicales en Scopus (3.91 veces en WoS), y que los documentos registran 5.95 más citas totales en Scopus (6.93 veces más en WoS). Los documentos paleárticos también registran más citas anuales y un índice h más alto, tanto en Scopus como en WoS. Scopus recuperó más artículos para especies neotropicales (2 782 vs. 2 631 en WoS) y tuvo más citas (28 120 vs. 24 977 en WoS). Las diferencias para los indicadores de citas entre regiones fueron más marcadas en WoS. El índice h y el total de citas se ven muy afectados por la cantidad de estudios publicados, es decir, la región con más producción será la que tenga indicadores más altos. Los artículos neotropicales mostraron una mayor tasa de crecimiento en la última década, disminuyendo la brecha entre ambas regiones. Conclusión: Existe un sesgo regional en WoS y Scopus, que recuperan más artículos y citas sobre mamíferos paleárticos que sobre mamíferos neotropicales; este sesgo es peor en WoS y significa que se necesita un aumento urgente en la investigación indexada sobre especies neotropicales para estar al nivel de la investigación paleártica.

Brain teratoma in a free-ranging mallard (Anas platyrhynchos) - case report / [Teratoma cerebral em um pato-real (Anas platyrhynchos) de vida livre - relato de caso]

Teratoma is a rare neoplasia with differentiation in two or three germ cell lines. Intracranial teratoma in birds has rarely been reported, especially affecting the brain. This is the first report of a brain teratoma in a mallard with neurological clinical signs. The neoplasm was characterized as a mature brain teratoma, extending from the cerebellum to the brainstem, and with one nodule in the cortex.(AU)

O teratoma é uma neoplasia rara, com diferenciação em duas ou três linhagens de células germinativas. Teratomas intracranianos, em aves, são raramente relatados, principalmente, com localização cerebral. Este é o primeiro relato de teratoma cerebral em um pato-real com sinais clínicos neurológicos. A neoplasia foi caracterizada como um teratoma cerebral maduro, estendendo do cerebelo ao tronco encefálico e com um nódulo no córtex.(AU)
