Abstract Objective: To measure pain in postoperative knee arthroscopy patients after undergoing treatment with therapeutic laser vs. TENS currents. Materials and method: An experimental, longitudinal, prospective, and comparative study was carried out that included 14 patients who attended the Physical Medicine and Rehabilitation area of the Hospital Central Militar, identified with the diagnosis of postoperative knee arthroscopy, through randomization. simple, by lottery, to include patients in the work groups: treatment with therapeutic laser vs treatment with TENS currents. The visual analogue scale was applied in the evaluation, and measurement of both knees was carried out by circometry, pre- and post-treatment to measure edema. The analysis was carried out with the statistical program SPSS version 26 and the student's T test was used. Significance level p<0.05. Results: A total of 14 patients entered the study, 7 were treated with therapeutic laser and 7 with TENS currents. 50% (7 patients) were women and 50% (7 patients) were men. The average age was 44.85 years. When analyzing the visual analog scale, in the pre- and post-treatment evaluation, both groups decreased their pain intensity with statistically significant differences (with a standard deviation of 1.15 for TENS and a standard deviation of 1.35). When comparing both results, a difference was observed. statistically significant difference in favor of TENS Currents over therapeutic laser p<0.0001. Conclusions: In both treatments, both the therapeutic laser and the TENS currents, improvements were observed in the pain perceived by the patients. Having a greater reduction in pain with TENS currents. Therefore, in this study we conclude that treatment with TENS currents is more effective than therapeutic laser in pain management in post-knee arthroscopy patients. No improvement in edema was observed in any of the treatments.

Ectoparasite insects of bats from the fields and weedlands eco-region of Argentina

New information is presented for bats and their ectoparasite insects from the Argentine Field and Weedlands Ecoregion. Bats of the families Molossidae, Phyllostomidae and Vespertilionidae containing ectoparasites belonging to families Polyctenidae (Hemiptera), Nycteribiidae and Streblidae (Diptera) were collected. Here is presented the first record of Hesperoctenes cartus Jordan, 1922 for Argentina. Basilia plaumanni Scott, 1940 and H. vicinus Jordan, 1922 are added to the province of Misiones and Paratrichobius longicrus (Miranda Ribeiro, 1907) is added to the province of Corrientes. Additionally, the distributions of some ectoparasite insects are extended and new host-ectoparasite associations are reported.(AU)

Using isotope data to characterize and date groundwater in the southern sector of the Guaraní Aquifer System.

The Guaraní Aquifer System (SAG) is the largest transboundary aquifer in Latin America, extending beneath parts of Brazil, Paraguay, Argentina, and Uruguay. This paper presents the results of recent hydrogeological studies in the southern portion of the SAG. Locally, the abundance of surface water bodies precluded the use of conventional hydrological tools to characterize groundwater flows. Geological, hydrochemical and environmental isotope investigations were integrated to postulate a revised hydrogeological conceptual model. The revised geological model has provided a better definition of the geometry of the aquifer units and outlined the relevance of regional faults in controlling flow patterns. The new potentiometric map is consistent with groundwater flow from the SAG outcrops to the centre of the Corrientes Province, where upwards flows were identified. Hydrochemical and isotope data confirmed the widespread occurrence of mixing. Noble gas isotopes dissolved in groundwater (4He and 81Kr/Kr) provided residence times ranging from recent recharge up to 770 ± 130 ka. Groundwater age modelling confirmed the role of the geological structures in controlling groundwater flow. The southern sector of the SAG is a multilayer aquifer system with vertical flows and deep regional discharge near the Esteros del Iberá wetland area and along the Paraná and Uruguay rivers.

Detection of Natural Infection by Leishmania sp. in Bats (Chiroptera, Mammalia) that Inhabit the City of Corrientes, Argentina.

Leishmaniasis is a zoonotic disease of importance in Argentina. It is important to be acquainted with its possible natural hosts and reservoirs. Bats have several reservoir attributes, which means they could fulfill these roles. The aim of this work was to investigate the presence of Leishmania sp. in bats that inhabit the city of Corrientes. Bats were captured and identified. From the captured specimens, spleen samples were taken and Leishmania sp. detection techniques were applied, including both optical microscopy and PCR. It was possible to capture 95 bat specimens belonging to 10 species. Using cytological preparations, a prevalence of 1.29% was detected and using PCR a prevalence of 32% was found. Our results confirm the presence of natural infection by Leishmania sp. in bats of the city of Corrientes which reveals the possibility of these animal species fulfilling a reservoir role for this disease.

La leishmaniose est une zoonose importante en Argentine. La connaissance de ses réservoirs possibles est essentielle. Les chauves-souris ont plusieurs attributs pour remplir ce rôle. L'objectif de ce travail était d'étudier la présence de Leishmania sp. chez les chauves-souris qui habitent la ville de Corrientes. Des captures de chauves-souris ont été faites et celles-ci ont été identifiées. Des échantillons de rates ont été prélevés sur ces spécimens pour rechercher Leishmania sp. en utilisant la microscopie optique et la PCR. Il a été possible de capturer 95 spécimens de chauves-souris appartenant à dix espèces. En utilisant des préparations cytologiques, une prévalence de 1,29 % a été détectée et en utilisant la PCR, une prévalence de 32 % a été trouvée. Nos résultats confirment la présence d'une infection naturelle par Leishmania sp. chez les chauves-souris de la ville de Corrientes, ce qui révèle la possibilité que ces espèces animales jouent un rôle de réservoir pour cette maladie.

Hallazgo del virus linfotrópico T humano 1 (HTLV-1) subtipo Cosmopolita subgrupo Transcontinental (Aa) y del HTLV-2 subtipo b en donantes de sangre de Corrientes / Detection of Human T lymphotropic virus 1 (HTLV-1) Cosmopolitan subtype Transcontinental subgroup (Aa) and HTLV-2 subtype b in blood donors of Corrientes

Resumen Se realizó un estudio epidemiológico molecular en una población de 9.422 donantes de sangre de la provincia de Corrientes (noreste de Argentina), con el fin de determinar la prevalencia del virus linfotrópico T del humano tipos 1 y 2 (human T-cell lymphotropic virus: HTLV-1/2), de identificar filogenéticamente a los subtipos/subgrupos de HTLV-1 y 2 encontrados y de realizar el análisis de mutaciones. Sobre la base de los resultados obtenidos, se demostró que tanto el HTLV-1 como el HTLV-2 se encuentran circulando en una población de bajo riesgo de Corrientes, si bien con una prevalencia similar a las de áreas no endémicas. Los estudios filogenéticos identificaron al subtipo Cosmopolita subgrupo Transcontinental (Aa) del HTLV-1 y al subtipo b del HTLV-2. Los donantes infectados no manifestaron antecedentes de riesgo tales como transfusiones, uso de drogas inyectables ni parejas sexuales de riesgo o seropositivas para HTLV-1/2. Estos resultados indican que estos virus fueron transmitidos de madre a hijo, posiblemente de generación en generación, y que estas cepas fueron introducidas en la población caucásica de esta región a partir de ascendientes originarios de áreas endémicas del país o por contacto producido tiempo atrás con individuos infectados de otros países. Nuestros resultados demuestran por primera vez la presencia de HTLV-1 y HTLV-2 en la provincia de Corrientes. Y si bien se puede considerar a esta provincia como área no endémica, se destaca la necesidad de incluir a estos retrovirus en un programa nacional de salud pública, con el fin de contar con profesionales capacitados para realizar su diagnóstico y brindar la información necesaria en relación con la atención primaria y el seguimiento de los pacientes.

Abstract A molecular epidemiological study was conducted in a population of 9422 blood donors in the province of Corrientes, Northeastern Argentina, to determine the prevalence of Human T-cell lymphotropic virus types 1 and 2 (HTLV-1/2), the phylogenetic identification of HTLV-1 and 2 subtypes/subgroups and perform a mutation analysis. Based on the results obtained, it was shown that both HTLV-1 and HTLV-2 are circulating in a low-risk population of Corrientes, although with a similar prevalence to that of non-endemic areas. Phylogenetic studies identified the HTLV-1 Cosmopolitan subtype Transcontinental subgroup (Aa), and the HTLV-2 subtype b. Infected donors reported neither a history of risk factors such as transfusions, intravenous drug use, nor risky or HTLV-1/2 seropositive sexual partners. These results suggest that these viruses were transmitted from mother to child, possibly from generation to generation, and that these strains were introduced into the Caucasian population of this region from ancestors originating from endemic areas of the country either from or through contact with individuals from other countries years ago. Our results demonstrate for the first time the presence of HTLV-1 and HTLV-2 in the province of Corrientes. Moreover, although the province can be considered a non-endemic area, the need to include these retroviruses in a national Public Health program is highlighted, in order to have qualified professionals duly trained to make their diagnosis and provide the necessary information in relation to primary care and patient follow-up.

Cercariae (Digenea: Strigeidae, Diplostomidae) in Biomphalaria straminea (Planorbidae) from a rice field in Northeastern Argentina / Cercarias (Orden: Strigeidae, Diplostomidae) en Biomphalaria straminea (Planorbidae) de un campo de arroz en el Nordeste Argentino

AbstractThe rice fields can provide habitats for many species of aquatic invertebrates, as insects, molluscs, crustaceans; and vertebrates, as fish, amphibians, reptiles and birds, which may act as hosts in the life cycles of digenean parasites. In this context, the goal of the present study was to describe the cercariae found in Biomphalaria straminea from a rice field in Northeastern Argentina. This freshwater snail inhabits a wide variety of environments, favoring shallow, temporary and standing or slow-flowing freshwater bodies. For this study, snails were collected from the cultivated parcels and irrigated channels during the flooding periods (from the time of sowing to soon after harvesting of the rice) between December 2010 and May 2011 and December 2011 and April 2012, in a rice field from Corrientes province, one of the main rice producers of Argentina. A total of 5 510 snails were examined of which 26 were infected with three different larval trematodes belonging to Strigeidae, Furcocercaria V (0.40 %) and Furcocercaria XX (0.04 %), and Diplostomidae, Furcocercaria XIX (0.04 %). Furcocercaria XX and Furcocercaria XIX were present in one rice cultivation cycle, while Furcocercaria V was present in both rice cultivation cycles. The prevalence of the different furcocercariae was somewhat higher in the second rice cultivation cycle. The cercariae described are new records for Argentina that added to 53 cercariae previously reported for Biomphalaria spp. in different aquatic environments of country. The study of the digenean larval in rice fields is important because contribute to the knowledge of the biodiversity of these environments.

ResumenLos campos de arroz pueden proporcionar hábitats para muchas especies de invertebrados acuáticos, como insectos, moluscos, crustáceos; y vertebrados, como peces, anfibios, reptiles y aves, los cuales pueden actuar como hospedadores en los ciclos de vida de los parásitos digeneos. En este contexto, el objetivo del presente estudio fue describir las cercarias encontradas en Biomphalaria straminea de un campo de arroz en el Nordeste Argentino. Este caracol de agua dulce habita una amplia variedad de ambientes, principalmente cuerpos de agua superficiales, estancados o de flujo lento. Para este estudio, los caracoles fueron recolectados de las parcelas cultivadas y los canales de riego durante los periodos de inundación (desde la siembra hasta poco después de la cosecha del arroz) entre diciembre 2010 y Mayo 2011 y Diciembre 2011 y Abril 2012, en un campo de arroz de la provincia de Corrientes, una de las principales productoras de arroz de Argentina. Un total de 5 510 caracoles fueron examinados de los cuales 26 estuvieron infectados con tres trematodes larvales pertenecientes a Strigeidae, Furcocercaria V (0.40 %) y Furcocercaria XX (0.04 %), y Diplostomidae, Furcocercaria XIX (0.04 %). Furcocercaria XX y Furcocercaria XIX estuvieron presentes en un ciclo de cultivo de arroz, mientras que Furcocercaria V estuvo presente en ambos ciclos de cultivo. La prevalencia de las diferentes furcocercarias fue algo mayor en el segundo ciclo de cultivo de arroz. Las cercarias descritas son nuevos registros para Argentina que se adicionan a las 53 cercarias previamente registradas para Biomphalaria spp. en diferentes ambientes acuáticos del país. El estudio de digeneos larvales en los campos de arroz es importante porque contribuye al conocimiento de la biodiversidad en estos ambientes.

Nuevos aportes al psicodiagnóstico de Rorschach. Presentación de un instrumento para medir las diferentes corrientes psíquicas presentes en la subjetividad / New contributions to the Rorschach psychodiagnostic. Presentation of an instrument to measure the different psychic currents present in subjectivity

El presente trabajo tiene por objetivo dar a conocer un instrumento de aplicación al Psicodiagnóstico de Rorschach denominado ADMR (Análisis Diagnóstico Multidimensional Rorschach), cuya finalidad es el establecimiento de un diagnóstico multivariado y más flexible, ya no pensado en términos de estructuras, sino más bien tomando en consideración las diferentes corrientes psíquicas que pueden coexistir en la subjetividad con predominio más o menos acusado de algunas de ellas: Neurótica; neurótica con rasgos de carácter; narcisistas no psicóticas; psicóticas, tóxicas y/o traumática, y aquellas que implican el implemento de defensas funcionales tales como la defensa acorde a fines, la creatividad y la sublimación. En este sentido el ADMR fue pensado siguiendo los lineamientos teóricos del Algoritmo David Liberman (ADL), instrumento diseñado por el Dr. David Maldavsky.(AU)

This work aims to present an instrument of implementation to the Rorschach Psychodiagnostic called MRDA (Multidimensional Rorschach Diagnosis Analysis), whose purpose is the establishment of a more flexible and multivariate diagnostic, not conceived in terms of structures, but rather taking into consideration the different psychic currents that can coexist in subjectivity with more or less accentuated predominance of some of them: neurotic, neurotic with character traits; non psychotic narcissist; psychotic, toxic and/or traumatic, and those involving the employment of functional defenses such as the according to the goal defense, creativity and sublimation. In this sense, the MRDA was conceived following the theoretical guidelines of the David Liberman algorithm (DLA), an instrument designed by Dr. David Maldavsky.(AU)

Eficiencia de las unidades de conservación definidas en la Reserva Natural Iberá (Argentina) en la protección de la diversidad de reptiles / Efficiency of conservation units defined in Iberá Natural Reserve (Argentina) in protecting reptile's diversity

Ante la acelerada pérdida de biodiversidad causada por actividades humanas, las áreas protegidas (APs) constituyen la principal respuesta para mitigar esta crisis. La Reserva Natural Iberá (RNI) incluye 13000 km2 de territorios privados y fiscales, que contienen humedales y tierras altas con elevada biodiversidad, endemismos e importantes poblaciones de especies amenazadas. Para implementar su conservación, a finales del siglo pasado se definieron cinco Unidades de Conservación (UC) priorizadas en infraestructura y guardaparques, seleccionadas mediante criterios pobremente explicitados. En este trabajo definimos áreas prioritarias para la conservación (APC) usando los patrones de distribución de los reptiles en la RNI, para evaluar la eficiencia de las UC instauradas y detectar otras posibles áreas a ser consideradas en gestiones de conservación. La RNI se dividió en 28 celdas de 0,25° de latitud-longitud y mediante muestreos de campo y revisión de colecciones se obtuvieron 1 482 registros de 71 especies de reptiles computándose su presencia/ausencia en las celdas. Se calculó por celda riqueza específica e Índice Combinado de Biodiversidad (ICB) (que incluye rareza y grado de amenaza). Las APC fueron definidas mediante una búsqueda exacta (Complementariedad), obteniendo el mínimo conjunto de áreas que contuvieran a todas las especies y valores del ICB, lo que se denomina "eficiencia máxima". La superficie mínima necesaria que representa a todas las especies es de diez celdas (36%) y sólo dos incluyen UC actuales. Se necesitan adicionar ocho celdas para cubrir los vacíos de conservación de reptiles, particularmente en el norte de la RNI. Sobre 20 especies amenazadas o insuficientemente conocidas, 12 (60%) no fueron registradas en celdas con UC. Proponemos UC adicionales para efectivizar la protección de todos los reptiles e incluir especies amenazadas.

Owing to accelerated biodiversity loss caused by human activities, the protected areas (PAs) are the main response to mitigate this crisis. The Iberá Natural Reserve (INR) includes 13000 km2 of private and state lands, which contain wetland and upland areas with high biodiversity, endemism and significant populations of threatened species. In order to implement its conservation, late last century, five Units of Conservation (UC) were defined and prioritized due to infrastructure and park-rangers, although poorly selected by explicit criteria. We defined priority areas for conservation (APCs) using the distribution patterns of reptiles in the INR, in order to evaluate the efficiency of the five UC located within its boundaries and detect other possible areas to be considered in conservation efforts. The INR was divided into 28 quadrat-cells of 0.25° latitude-longitude and through field samplings and revision of collections we obtained 1482 records of 71 species of reptiles, computed their presence / absence in the cells. We estimated species richness and Combined Biodiversity Index (including rarity and degree of threat) by cell. APCs were defined by an exact search (complementarity index), obtaining the minimum set of areas containing higher values of the indexes used, which is called "maximum efficiency". The minimum area required to represent all species was ten cells (36%) and only two of them includes current UC. Add eight cells are needed to fill conservation gaps of reptiles, particularly in the north of the INR. About 20 threatened or poorly known species, 12 (60%) were not recorded in cells with UC. We proposed additional UC in order to protect all reptiles and include threatened species.

Add eight cells are needed to fill conservation gaps of reptiles, particularly in the north of the INR. About 20 threatened or poorly known species, 12 (60%) were not recorded in cells with UC. We proposed additional UC in order to protect all reptiles and include threatened species.

Eficiencia de las unidades de conservación definidas en la Reserva Natural Iberá (Argentina) en la protección de la diversidad de reptiles / Efficiency of conservation units defined in Iberá Natural Reserve (Argentina) in protecting reptile's diversity

Ante la acelerada pérdida de biodiversidad causada por actividades humanas, las áreas protegidas (APs) constituyen la principal respuesta para mitigar esta crisis. La Reserva Natural Iberá (RNI) incluye 13000 km2 de territorios privados y fiscales, que contienen humedales y tierras altas con elevada biodiversidad, endemismos e importantes poblaciones de especies amenazadas. Para implementar su conservación, a finales del siglo pasado se definieron cinco Unidades de Conservación (UC) priorizadas en infraestructura y guardaparques, seleccionadas mediante criterios pobremente explicitados. En este trabajo definimos áreas prioritarias para la conservación (APC) usando los patrones de distribución de los reptiles en la RNI, para evaluar la eficiencia de las UC instauradas y detectar otras posibles áreas a ser consideradas en gestiones de conservación. La RNI se dividió en 28 celdas de 0,25° de latitud-longitud y mediante muestreos de campo y revisión de colecciones se obtuvieron 1 482 registros de 71 especies de reptiles computándose su presencia/ausencia en las celdas. Se calculó por celda riqueza específica e Índice Combinado de Biodiversidad (ICB) (que incluye rareza y grado de amenaza). Las APC fueron definidas mediante una búsqueda exacta (Complementariedad), obteniendo el mínimo conjunto de áreas que contuvieran a todas las especies y valores del ICB, lo que se denomina "eficiencia máxima". La superficie mínima necesaria que representa a todas las especies es de diez celdas (36%) y sólo dos incluyen UC actuales. Se necesitan adicionar ocho celdas para cubrir los vacíos de conservación de reptiles, particularmente en el norte de la RNI. Sobre 20 especies amenazadas o insuficientemente conocidas, 12 (60%) no fueron registradas en celdas con UC. Proponemos UC adicionales para efectivizar la protección de todos los reptiles e incluir especies amenazadas.(AU)

Owing to accelerated biodiversity loss caused by human activities, the protected areas (PAs) are the main response to mitigate this crisis. The Iberá Natural Reserve (INR) includes 13000 km2 of private and state lands, which contain wetland and upland areas with high biodiversity, endemism and significant populations of threatened species. In order to implement its conservation, late last century, five Units of Conservation (UC) were defined and prioritized due to infrastructure and park-rangers, although poorly selected by explicit criteria. We defined priority areas for conservation (APCs) using the distribution patterns of reptiles in the INR, in order to evaluate the efficiency of the five UC located within its boundaries and detect other possible areas to be considered in conservation efforts. The INR was divided into 28 quadrat-cells of 0.25° latitude-longitude and through field samplings and revision of collections we obtained 1482 records of 71 species of reptiles, computed their presence / absence in the cells. We estimated species richness and Combined Biodiversity Index (including rarity and degree of threat) by cell. APCs were defined by an exact search (complementarity index), obtaining the minimum set of areas containing higher values of the indexes used, which is called "maximum efficiency". The minimum area required to represent all species was ten cells (36%) and only two of them includes current UC. Add eight cells are needed to fill conservation gaps of reptiles, particularly in the north of the INR. About 20 threatened or poorly known species, 12 (60%) were not recorded in cells with UC. We proposed additional UC in order to protect all reptiles and include threatened species.(AU)

The masquerade game: marine mimicry adaptation between egg-cowries and octocorals.

Background. Background matching, as a camouflage strategy, is one of the most outstanding examples of adaptation, where little error or mismatch means high vulnerability to predation. It is assumed that the interplay of natural selection and adaptation are the main evolutionary forces shaping the great diversity of phenotypes observed in mimicry; however, there may be other significant processes that intervene in the development of mimicry such as phenotypic plasticity. Based on observations of background mismatching during reproduction events of egg-cowries, sea snails of the family Ovulidae that mimic the octocoral where they inhabit, we wondered if they match the host species diversity. Using observations in the field and molecular systematics, we set out to establish whether the different egg-cowrie color/shape polymorphisms correspond to distinct lineages restricted to specific octocoral species. Methods. Collection and observations of egg-cowries and their octocoral hosts were done using SCUBA diving between 2009 and 2012 at two localities in the Tropical Eastern Pacific (TEP), Malpelo Island and Cabo Corrientes (Colombia). Detailed host preference observations were done bi-annually at Malpelo Island. We analyzed the DNA sequence of the mitochondrial genes COIand 16S rDNA, extensively used in phylogenetic and DNA barcoding studies, to assess the evolutionary relationship among different egg-cowrie colorations and morphologies. Results. No genetic divergence among egg-cowries associated to different species of the same octocoral genus was observed based on the two mitochondrial genes analyzed. For instance, all egg-cowrie individuals from the two sampled localities observed on 8 different Pacifigorgia-Eugorgia species showed negligible mitochondrial divergence yet large morphologic divergence, which suggests that morphologies belonging to at least two sea snail species, Simnia avena(=S. aequalis) and Simnialena rufa, can cross-fertilize. Discussion. Our study system comprised background-matching mimicry, of the masquerade type, between egg-cowries (Simnia/Simnialena) and octocorals (Pacifigorgia/Eugorgia/Leptogorgia). We observed mimicry mismatches related to fitness trade-offs, such as reproductive aggregations vs. vulnerability against predators. Despite the general assumption that coevolution of mimicry involves speciation, egg-cowries with different hosts and colorations comprise the same lineages. Consequently, we infer that there would be significant tradeoffs between mimicry and the pursuit of reproductive aggregations in egg-cowries. The findings of this study not only contribute to the understanding of the evolution of mimicry in egg-cowries, a poorly studied group of marine gastropods, but also to the development of a new biologically meaningful board game that could be implemented as a learning tool.

Factors that influence the beta-diversity of spider communities in northwestern Argentinean Grasslands.

Beta-diversity, defined as spatial replacement in species composition, is crucial to the understanding of how local communities assemble. These changes can be driven by environmental or geographic factors (such as geographic distance), or a combination of the two. Spiders have been shown to be good indicators of environmental quality. Accordingly, spiders are used in this work as model taxa to establish whether there is a decrease in community similarity that corresponds to geographic distance in the grasslands of the Campos & Malezales ecoregion (Corrientes). Furthermore, the influence of climactic factors and local vegetation heterogeneity (environmental factors) on assemblage composition was evaluated. Finally, this study evaluated whether the differential dispersal capacity of spider families is a factor that influences their community structure at a regional scale. Spiders were collected with a G-Vac from vegetation in six grassland sites in the Campos & Malezales ecoregion that were separated by a minimum of 13 km. With this data, the impact of alpha-diversity and different environmental variables on the beta-diversity of spider communities was analysed. Likewise, the importance of species replacement and nesting on beta-diversity and their contribution to the regional diversity of spider families with different dispersion capacities was evaluated. The regional and site-specific inventories obtained were complete. The similarity between spider communities declined as the geographic distance between sites increased. Environmental variables also influenced community composition; stochastic events and abiotic forces were the principal intervening factors in assembly structure. The differential dispersal capacity of spider groups also influenced community structure at a regional scale. The regional beta-diversity, as well as species replacement, was greater in high and intermediate vagility spiders; while nesting was greater in spiders with low dispersion capacity. Geographic distance, among other factors (climate, and active and passive dispersion capacity), explains assembly structure and the decrease spider community similarity between geographically distant sites. Spiders with the highest dispersal capacity showed greater species replacement. This may be due to the discontinuity (both natural and anthropic) of the grasslands in this ecoregion, which limits the dispersal capacity of these spiders, and their close dependence on microhabitats. The dispersal capacity of the least vagile spiders is limited by geographic distance and biotic factors, such as competition, which could explain the nesting observed between their communities.

Rasgos oceanográficos en el Golfo Dulce, Pacífico de Costa Rica: una revisión para la toma de decisiones en conservación marina / Oceanographic features of Golfo Dulce, Costa Rican Pacific: a review for decision-making in marine conservation

Resumen Se indagó, de septiembre del 2005 a noviembre del 2007, las propiedades oceanográficas físicas, químicas y biológicas (zooplancton) más relevantes del Golfo Dulce, Pacífico Sur de Costa Rica, y las tipologías meteorológicas de la zona, con el objetivo de analizarlas y hacerlas disponibles como referencia en el establecimiento de actividades adecuadas para su conservación, dado que es un ecosistema acuático único en Costa Rica. El patrón de circulación de las aguas en el Golfo Dulce es el típico de estuarios tipo fiordo, con una estratificación de flujo en la columna de agua. Las corrientes marinas superficiales alcanzaron velocidades cercanas a los 18cm/s en la región de entrada al Golfo, que disminuyeron al ampliarse el área del golfo donde las velocidades llegaron a alcanzar poco más de 5cm/s en el extremo noroeste, Rincón. Predominó el flujo superficial de este-oeste, mientras que en la zona de Puerto Jiménez la velocidad fue moderada de 5.4cm/s con dirección sur. Se detectaron velocidades mayores cercanas al umbral de la entrada del golfo (17.8cm/s) y en el fondo el ámbito fue de 2.0cm/s a 4.8cm/s. Se establecieron cinco sitios de muestreo denominados GD1, GD2, GD3, GD4 y GD5, que se visitaron en cinco ocasiones, excepto en GD5 que se visitó solo una vez. No se detectó la ausencia de oxígeno disuelto en las aguas profundas del Golfo (70m a los 140m), aunque las concentraciones fueron bajas (0.25mg/L a 1.10mg/L). La distribución de las concentraciones de los nutrimentos reflejó los patrones usuales para sistemas estuarinos a nivel horizontal, y a nivel vertical las concentraciones de fosfato y silicato fueron mayores al descender en la columna de agua, tanto en la estación lluviosa como en la seca. La descomposición de la materia orgánica fue evidente puesto que las concentraciones de nitrato fueron incrementándose en las aguas profundas. De los datos de concentración de nutrimentos, se deduce que el Golfo Dulce puede ser considerado como un cuerpo de agua que se mantiene en un estado de muy buena calidad ambiental. El grupo zooplánctico dominante fue el de los copédodos (44%-83.6%). Los vientos oeste ecuatoriales se detectaron en junio y fueron más intensos entre septiembre y octubre, lo que correspondió con promedios altos de altura de las olas. A su vez, los vientos alisios de diciembre a abril disminuyeron la energía del oleaje que entra al golfo y por lo tanto la altura promedio de las olas. El ciclo anual de la precipitación fue un patrón bimodal típico del Pacífico de América Central, con máximos en mayo y octubre, con la interrupción debida al veranillo o canícula, y un mínimo de precipitación ocurrió en febrero. Golfo Dulce es un ambiente único en todo el Pacífico Este Tropical, y aunque parezca mostrar condiciones ambientales saludables, está amenazado por muchas actividades humanas; ante todo urge el establecimiento de políticas de ordenamiento y planificación de las mismas, para proteger el ecosistema bajo los principios de uso sostenible.

Abstract From September 2005 to November 2007 we studied the meteorological typologies and the physical, chemical and zooplankton oceanography of Golfo Dulce, a unique aquatic ecosystem in the South Pacific of Costa Rica. The water circulation pattern in Golfo Dulce is typical of fjord-type estuaries, with flux stratification within the water column. Surface water currents reached speeds near 18cm/s in the vicinity of the sill and diminished inward to the northwest at around 5cm/s. The east-west flux was predominant, whereas near Puerto Jiménez the speed was a moderated 5.4cm/s with a south direction. Higher speeds were found near the sill (17.8cm/s) and at the bottom (2.0cm/s to 4.8cm/s). One station was visited once, five were visited five times each. Dissolved oxygen was not absent in deep waters (70m to 140m), but concentrations were low (0.25mg/L to 1.10mg/L). Nutrient concentrations and distribution had the usual horizontal estuarine patterns and for the vertical level phosphate and silicate concentrations increased with depth. Decomposition of organic matter was evident because nitrate concentrations were higher in deep waters. Surface nutrient concentrations indicated the gulf has good environmental quality that sustains a variety of life. Copepods dominated zooplankton (44%83.6%). The strongest equatorial westerlies were detected between September and October, coincident with higher wave heights. The trade winds blowing from December to April reduced the energy of entering waves and therefore the mean wave height. The annual rainfall cycle was the typical bimodal pattern from the Central America Pacific, with maxima in May and October, except for the midsummer interruption, and minimum rain was on February. Golfo Dulce is a unique environment in the Eastern Tropical Pacific, shows healthy environmental conditions, and is threatened; therefore we urge the establishment of zoning policy for human activities, and to improve protection under the principles of sustainable use.

Corrientes educativas que han permeado la formación de enfermería en la Escuela Nacional de Enfermería y Obstetricia / Educational fl ows that have permeated the nursing education in the National School of Nursing and Midwifery

Este artículo presenta una revisión de los modelos pedagógicos que tradicionalmente se han usado en la formación del profesional de enfermería de la Escuela Nacional de Enfermería y Obstetricia de la Universidad Nacional Autónoma de México (UNAM) y también presenta cómo esos modelos han infl uido en las características del ejercicio de la profesión. El modelo enseñanza-aprendizaje se ha venido presentando en diversas modalidades, como la tradicionalista, la conductista y actualmente, se pretende que sea constructivista. Finalmente se puede concluir en el presente escrito que a través de la historia de la enfermería se puede observar que el patrón curricular está orientado al desarrollo de habilidades manuales y procedimentales en los que los alumnos, desde el nivel preescolar hasta el superior, conservan un enfoque educativo tradicional con el que se ha formado la mayor parte del personal de la salud. Consecuentemente este modelo educativo genera la pasividad del alumno resaltando la autoridad y el poder del profesor como poseedor del conocimiento

This article presents a review of pedagogical models that traditionally have been used in professional formation of nurses from the National School of Nursing and Midwifery (ENEO) of the National Autonomous University of Mexico (UNAM) and how these models have infl uenced the characteristics of the practice of the profession the teaching learning model has been presented in different modalities, such as traditionalist, behavioral and currently intended to be constructive. Finally it can be concluded in this paper is that through the history of nursing can be seen that the curricular pattern is oriented to the development of manuals and procedural skills, where students from preschool to upper retain a traditional educational approach which has trained the majority of the health care personnel. Consequently this educational model generates student passivity highlighting the power and authority of the teacher as the possessor of knowledge
