Many species of opossum (Didelphimorphia) are known to fluoresce, but the significance of this characteristic is unclear. In the interests of contributing to the faunal inventory of fluorescence in Didelphids, we examined 62 specimens of 10 species of Paraguayan opossums under a UV light and describe the patterns observed. Of particular interest is...

Todos los especímenes paraguayos de la comadrejita ágil chaqueña han sido capturados en el suelo, a pesar de los esfuerzos simultáneos de captura en los árboles. Dos individuos de C. chacoensis fueron descubiertos en dos ocasiones separadas descansando sobre una gran masa de hojas dentro de dos viejos nidos de C. chrysopterus que habían caído sobre...

Here we present 19 new or significant herpetofauna departmental records from five Paraguayan departments; Alto Paraguay, Misiones, Ñeembucú, Presidente Hayes and San Pedro with the interest of updating currently understood distributions. Many of these records are common species highlighting the gaps still prevalent in Paraguayan herpetofauna and th...

Cattle in wetlands impact water quality through waste excretion, which deposits excess nutrients, as well as decreasing the biomass and height of vegetation through trampling and herbivory. Amphibians are sensitive to these changes due to their porous skin and reliance on vegetated microhabitats. Previous studies examining the effect of cattle on a...

The avifauna of Ñeembucú is currently one of the most understudied within Paraguay, with the true diversity present likely to be greatly underrepresented. In the interests of contributing an up-to-date species list for the department, we present 46 new documented bird records, as well as a list of all 330 documented birds within the department. We...

Amphisbaena prunciolor is known from very few Paraguayan reports in the southern department of Itapúa. Often confused with A. darwinii (including 'heterozonata' and 'trachura') and A. albocingulata, it is identified by the combination of a rounded head, checkerboard pattern on the ventral surface, presence of a postmalar scale row, and caudal annul...
