Proteomic and functional analyses of Lachesis acrochorda snake venom from the Valle del Cauca Department of Colombia.

Lachesis acrochorda envenomation has a lethality rate of approximately 90%. Despite its high lethality, little is known about its local and systemic effects and its relationship with its protein content. Thus, to increase knowledge of L.

First functional and proteomic analysis of Bothrops asper snake venom from Gorgona Island - Colombia, and its comparative characterization with two Colombian Southwest ecoregions.

Bothrops asper envenoming is a public health problem in tropical regions of Latin America. Bothrops asper has spread until Gorgona Island in the Pacific Colombian Ocean, but its biochemical venom characterization is poorly known. Thus, to increase knowledge on Bothrops species venoms, we developed for the first time the proteomic analysis using a shotgun approach and performed functional evaluations relevant to its toxicity and compared with two Colombian Southwest ecoregions from the Pacific and Western sides.

Complex patterns of differentiation and gene flow underly the divergence of aposematic phenotypes in Oophaga poison frogs.

Hybridization and introgression can have complex consequences for both species evolution and conservation. Here, we investigated the origin and characteristics of a putative hybrid zone between two South American poison dart frog species, Oophaga anchicayensis and the critically endangered Oophaga lehmanni, which are heavily sought after on the illegal pet market. Using a combination of phenotypic (49 traits) and genomic (ddRADseq) data, we found that the putative hybrids are morphologically distinct from their parental species and confirmed genomic signatures of admixture in these populations.
