The native species of amphibians and reptiles of Uruguay were categorized according to the IUCN Red List criteria. Out of 47 amphibian species, seven are listed as Critically Endangered (CR), five as Endangered (EN), one as Vulnerable (VU), three as Near Threatened (NT), and two as Data Deficient (DD); the remaining species are considered to be Least Concern (LC). Among the 64 species of reptiles evaluated, one is listed as Critically Endangered (CR), seven as Endangered (EN), two as Vulnerable (VU), one as Near Threatened (NT) and seven as Data Deficient (DD); the rest are considered to be Least Concern (LC). The use of these results as an additional criterion in the definition of protected areas in Uruguay will contribute towards the conservation of the aforementioned threatened species and their associated ecosystems.

In Uruguay, there was no information about the variations degree in Bothrops pubescens venoms until the present work, in which we investigated intraspecific venom variation using polyacrylamide gel electrophoresis (SDS-PAGE). We found some differences in the venom protein profile; however, they were not related to the parameters studied (geographic distribution, weight, sex, and captivity time). Moreover, we distinguished two different groups in relation to band densities at 49 and 57 kDa. Specimens with predominant density in the 49kDa band tend to be predominantly females. Weight distribution in this group extended for all the range (150-1500 g) with an average weight of 720 g. The other group (57kDa predominant band) showed restricted weight range (150-400 g) with an average weight of 280 g. Cluster analysis was also performed. The variability observed in the venom profile probably corresponds to genetic variations

Las mordeduras por ofidios del género Micrurus son infrecuentes a nivel mundial. En Uruguay los emponzoñamientos son exclusivamente por Bothrops alternatus y B. pubescens (crucera y yarará). Desde 1986 la notificación de casos de ofidismo es obligatoria ante el Centro de Información y Asesoramiento Toxicológico (CIAT), no habiéndose registrado casos por mordedura de Micrurus altirostris hasta este reporte clínico. Se presenta el primer caso clínico de mordedura por víbora de coral (Micrurus altirostris) en nuestro país, destacándose la gravedad del mismo dada la neurotoxicidad que presentó evolucionando a parálisis respiratoria que requirió ventilación mecánica invasiva. Buena evolución con el sostén de funciones vitales implementado, no requiriendo neostigmina, logrando extubación y reversión completa del cuadro al cuarto día. El antídoto de este emponzoñamiento (suero antielapídico) presenta limitada disponibilidad a nivel mundial, no contando con el mismo en nuestro país, por lo que en casos graves, particularmente con falla respiratoria, la asistencia ventilatoria mecánica es el principal pilar terapéutico.

Since its inception, photography has played an important role as a documentary tool. It has been used to communicate and disseminate biodiversity research and conservation projects in different parts of the world. Today, the extraordinary technological development and popularity of photography has allowed it to be used to collect data for different types of scientific projects and to facilitate a much more fluid exchange of information between the scientific community and the public, for example in citizen science programmes. However, a paradigm shift is now being proposed for photography to move beyond its purely artistic sense to reveal its informative and knowledge-generating potential in the field of conservation.
