Abstract Variation in body size represents one of the crucial raw materials for evolution. However, at present, it is still being debated what main factor affecting or if final consequence several factors acting synergistically. To evaluate this, widespread species seem to be suitable models because different populations occur along a geographical gradient and under contrasted climatic environmental conditions. Here we describe spatial pattern variation sexual dimorphism snouted treefrog...
Four species of Pseudopaludicola, Pseudopaludicola boliviana, P. falcipes, mystacalis and ternetzi, are usually cited for Paraguay. However, after analyzing 407 specimens assigned to this genus in herpetological collections the country, we conclude that there no falcipes Paraguayan or vouchers literature, almost all individuals referred ternetzi most probably ameghini. At same time, a recently described species, motorzinho, is recorded first time country. Information on distribution these...
In this study we assessed the efficacy of Visible Implant Alphanumeric (VIA) for marking adults and juveniles Neotropical treefrog Scinax nasicus. We evaluated success technique in identification individuals prevalence tags field. As a control, marked same through toe-clipping. Of 196 individuals, 57 were recaptured 7-month period. Only one mark was unreadable because it located too deep skin. found case tag expulsion two inverted tags. Almost complete regeneration adhesive disk observed by...
ABSTRACT Species tend to be less abundant at the limits of their geographic distribution. Giant and lesser anteaters have southernmost in Argentina Paraguay, where scarce information exists regarding ecology conservation. We present a study carried out Paraguay River floodplain, an area dedicated cattle rearing using native grasses subtropical flooded savanna associated with naturally occurring forest islets, wetlands palm groves. Using camera-traps within three different types, we estimated...
Abstract Ontogenetic colour change (OCC) is defined as the progressive and non-reversible process of changes in colouration organisms associated with their development. Among many vertebrate groups, amphibians are particularly impressive for strikingly wide variety colours, patterns, signals, whose evolutionary ecological significance have been poorly studied. Elachistocleis comprises 18 species currently separated into two main groups based on ventral pattern: one immaculate other specks...
Chacophrys pierottii es una rana de tamano mediano con habitos depredacion generalistas y oportunistas, su dieta incluye pequenos vertebrados artropodos. Durante excursion al Parque Nacional Defensores (Departamento Alto Paraguay, Paraguay), en la base del Cerro Leon observamos un macho adulto alimentandose Trachycephalus typhonius juvenil cerca estanque temporal, formado por las intensas lluvias caidas par dias antes. Nuestro hallazgo ...
Se estudió la abundancia y el uso de hábitat Crax fasciolata utilizando cámaras trampa en distintos tipos bosques Chaco Húmedo Paraguay. En un total 996 díascámara esfuerzo muestreo se obtuvieron 114 registros, mayoría ellos uno dos individuos, con máximo cinco individuos. La mayor cantidad registros obtuvo bosque ripario, éxito captura 20%, durante primavera, 22%. especie mostró actividad diurna mañana. recomienda profundizar estas investigaciones analizando no solo tipo sino también época...
Gymnophthalmidae is a highly diverse family of small to medium sized South American lizards. In Paraguay, seven species are currently known. Among these, Colobosaura modesta and Micrablepharus maximiliani two poorly sampled in the country: C. was only recorded localities Amambay San Pedro Departments, whilst M. Central, Cordillera, Paraguarí Departments. During field surveys 2022 we captured one three individuals. The record 134.7 km west from nearest known locality, it third confirmed...
Physalaemus riograndensis es una especie cuya distribución se extiende desde Uruguay al Noreste de Argentina, Sureste Brasil y en dos localidades Paraguay, los Departamentos Presidente Hayes e Itapúa. En la está categorizada como datos insuficientes debido a pocos registros ninguna información sobre su ecología. esta nota registramos nueva localidad donde encontramos un ensamble activo sabana inundable luego fuertes lluvias. Además, modelamos utilizando métodos uso extensivo para determinar...

Stenocercus is a genus widely distributed geographically and ecologically, from the north of Andes mountain range surrounding lowlands, to southern Brazil central Argentina. Herein we present first records doellojuradoi for Paraguay. We discussed morphological variations found in specimens Paraguay, addition possible threats conservation species locality where it was recorded.
Oxyrhopus petolarius se distribuye desde el sur de México hasta Departamento Itapúa en Paraguay y la provincia Misiones Argentina.
