El estudio analiza las características de la piel en dos especies de anfibios, Leptodactylus mystacinus y Leptodactylus apepyta, que presentan áreas ecotonales en común. Para ello se tomaron muestras de la región dorsal, ventral e inguinal de ejemplares adultos de ambas especies, de cuatro especímenes, dos de cada especie, pertenecientes a la colección Herpetológica del Museo Nacional de Historia Natural del Paraguay (MNHNP) y se procesaron histológicamente. Los datos icrométricos de la piel se registraron y analizaron estadísticamente con un nivel de confianza de95%, encontrándose que el promedio del grosor de la piel. Difiere entre las especies, en L. apepyta, el grosor promedio es de 128.44 µm en la región dorsal, 81.36 µm en la ventral y 74.41 µm en la inguinal, mientras que en L. mystacinus es de 139.81 µm, 49.31 µm y 102.92 µm en las mismas regiones, respectivamente. También se encontraron variaciones morfológicas en la epidermis y dermis de ambas especies,los análisis estadísticos revela una distribución normal de los datos, concluyéndose que, aunque los tegumentos de ambas especies son similares a los de otros anfibios, existen diferencias significativas en el grosor de la piel, siendo L. mystacinus más gruesa. Además, se observa la presencia de la capas de Eberth-Katschenko y glán-dulas con una diferenciación en su maduración para ambas especies.

Las serpientes en general son animales solitarios, aunque existen reportes de que varias especies forman agrupamientos por diferentes motivos, reproducción, resguardo climático, o incluso cuestiones sociales. El comportamiento de los escolecofidios es poco conocido, debido principalmente a sus hábitos fosoriales y pequeño tamaño. Los agrupamientos en esta familia fueron reportados para algunos géneros y dentro de estos para unas pocas especies. En este trabajo, se presentan por primera vez datos sobre agrupamientos en Epictia albipuncta, formados por varias hembras junto a varios machos; dos de los tres agrupamientos fueron encontrados al final de la época invernal, por lo que parecería que estos estarían relacionados con cuestiones climáticas más que con la reproducción. De todas maneras, la información es escasa, por lo no se puede explicar completamente los agrupamientos observados.

Given their great importance in aquatic ecosystems, the literature on aquatic and semi-aquatic Heteroptera is quite extensive worldwide. However, relatively little literature is available on the taxonomy and distribution of aquatic and semi-aquatic Heteroptera in the Gharb Plain, specifically the two wetland areas classified as Ramsar sites, the Biological Reserve of Sidi oughaba and the Merja of Fouarat. Therefore, the present research aims to study the community of aquatic Heteroptera and the physico-chemical variables of these two wetland areas in the Gharb Plain. Additionally, the research aims to document and authenticate the historical review of aquatic and semi-aquatic Heteroptera in these wetlands. The results obtained show the existence of two groups of Heteroptera species. One group consists of species that are found in several environments due to their broad ecological tolerance. This is the case of, Gerris lacustris (Linnaeus, 1758), G. lateralis (Schummel, 1832), Corixa affinis (Leach, 1817), Notonecta glauca rufescens (Poisson, 1933), Anisops sardia (Herrich-Schaeffer, 1849), Plea leachi (McGregor, Kirk, 1899), Naucoris maculatusconspersus (Stål, 1876), Hydrometra stagnorum (Linnaeus,1758) and Mesovelia vittigera (Horváth, 1895). On the contrary, species conditioned by several physicochemical factors of the environment, Stenoic species, such as Sigara lateralis (Leach, 1817), S. stagnalis (Leach, 1817), Naucoris maculatus angustior (Lethierry, 1877), Nepa rubra rubra (Linné, 1758) and Gerris thoracicus (Schummel, 1832).

The distribution and abundance of fish for the Orinoco River basin drainages are influenced by hydrometric seasonality and the structural complexity of the habitat, so understanding how fish assemblages are structured on a temporal and spatial scale is essential for biological conservation. Therefore, the purpose of this study was to describe the fish assemblage for the Mitimiti stream and test the hypothesis of spatial and temporal variation. To do this, collections were made at four sampling stations on the Mitimiti stream, during three contrasting rainfall seasons, with the help of a 10 m x 1.5 m trawl net and a 2 mm mesh eye. The diversity of fish assemblages was analyzed using Hill numbers, abundance-based dissimilarity, and a Canonical Correspondence Analysis (CCA). In total, 2493 individuals and 115 species were recorded, where the orders with the highest dominance were Characiformes and Blenniiformes. Regarding the diversity of order q = 0, no significant differences were found between the hydrological periods and the sampling stations, however, the low water period and St3 exhibited the highest species richness. The most dissimilar hydrological period was the high water season and the variables that significantly influenced fish assemblage were water temperature (p = 0.02) and dissolved oxygen (p = 0.05).

The Andean condor (Vultur gryphus) is an emblematic species of the Andes. It is the largest vulture in the world, and it is at the top of the food chain. His image has been present in the memorial of cultures, festivals and beliefs of Andean people and persists until now, as current symbolism of the Andean cultures. In order to evaluate the general data of the Andean condor based on urban population perspectives, surveys were used and distributed over the internet in Ecuador under a socioeconomic classification. The information was analyzed using Chi2 tests and generalized linear models. 726 responses were obtained from people between 18 and 71 years old. All the models generated were reliable. The results show that general information such as recognizing the species, knowing its diet and perceiving that it is an endangered species, is known by the urban population. Unknown aspects of the Andean condor are its size, flight distance and the number of eggs per clutch. The Andean condor has a positive perception as a vulture, and a low percentage considers it a harmful species capable of preying live animals. Variables such as gender, outdoor activities and age proved gaps in the natural history of the Andean condor in some social spaces. We suggest as an alternative to completely cover the gaps, environmental education actions directed to these social spaces.

Varroosis and nosemosis are diseases that affect honey bees (Apis mellifera) and therefore have a great impact on beekeeping worldwide. These parasites can be dispersed by drones and, in the case of Varroa destructor (etiological agent of varroasis), its presence has been reported in areas of natural fertilization of A. mellifera, known as Drone Congregation Areas (DCA). Previously, several DCAs were identified in Argentina and progress was made in their topographic and genetic characterization, and sanitary studies were also initiated. In this study, three DCA and one apiary located in the province of Tucumán were monitored for four years, and the presence of V. destructor and Nosema sp. was evaluated. The results indicated the presence of V. destructor in the drone samples of the DCA throughout the study. Although a trend of decreasing parasitization over time was observed, no statistically significant differences were found between years or among the considered DCAs. The presence of Nosema sp. was detected for the first time in the DCA, with samples exhibiting high spore load. The results support the role of drones in the dynamics and dispersal of diseases and allow us to conclude that the analysis of DCAs represents a key tool for monitoring the health of bee populations, complementary to the analyses carried out in apiaries.

La salinización de cuerpos de agua es un problema creciente a nivel mundial, agudizado por las consecuencias del aumento de áreas desérticas y efectos del cambio climático. La salinización primaria es debida a efectos naturales (p.e: sustrato o clima) y la salinización secundaria es la alteración del ciclo de la sal producida por actividades antrópicas. Diversas especies, pertenecientes a comunidades de macroinvertebrados bentónicos, presentan tolerancia a elevados niveles de salinidad y logran dominar los ecosistemas en que habitan. Presentamos en este trabajo a tres taxones tolerantes a la salinidad de ríos de la provincia de Tucumán.
