Evento de depredación de Venado Soche (Mazama rufina, Pucheran, 1851) por Taira (Eira barbara Linnaeus, 1758) en el Parque Nacional Natural Chingaza, Colombia
Sociedad Colombiana de Mastozoologia, 2020Co-Authors: Rodríguez O. Juliana, Bohórquez, Juan Sebastián, Raigozo, Oscar Gabriel, Clavijo AlexanderAbstract:The Tayra (Eira barbara) is one of the least studied carnivores and very little is known about its natural history. The Species has omnivorous diet, and is an opportunistic hunter, especially of rodents and the offspring of some Arboreal Species such as monkeys or sloths. In this note we report the description of a predation event done by a Tayra to a Red Brocket deer (Mazama rufina), recorded on video in the Chingaza National Natural Park, Colombia.La Taira (Eira barbara) es uno de los carnívoros menos estudiados y poco se conoce acerca de su historia natural. La especie posee hábitos alimentarios omnívoros y se caracteriza por ser cazadora oportunista sobre todo de roedores y crías de monos o perezosos. En esta nota reportamos la descripción de un evento de depredación por parte de una Taira a un Venado Soche (Mazama rufina), capturado mediante un video en el Parque Nacional Natural Chingaza, Colombia

Structural and Molecular Diversification of the Anguimorpha Lizard Mandibular Venom Gland System in the Arboreal Species Abronia graminea
Journal of Molecular Evolution, 2012Co-Authors: Ivan Koludarov, Kartik Sunagar, Eivind A. B. Undheim, Timothy N. W. Jackson, Tim Ruder, Darryl Whitehead, Alejandro C. Saucedo, G. Roberto Mora, Alejandro C. Alagon, Glenn KingAbstract:In the past, toxinological research on reptiles has focused principally on clinically important Species. As a result, our understanding of the evolution of the reptile venom system is limited. Here, for the first time, we describe the structural and molecular evolutionary features of the mandibular toxin-secreting gland of Abronia graminea , a representative of one of the poorly known and entirely Arboreal lineages of anguimorph lizards. We show that the mandibular gland is robust and serous, characters consistent with those expected of a toxin-secreting gland in active use. A wide array of transcripts were recovered that were homologous to those encoded by the indisputably venomous helodermatid lizards. We show that some of these toxin transcripts are evolving under active selection and show evidence of rapid diversification. Helokinestatin peptides in particular are revealed to have accumulated residues that have undergone episodic diversifying selections. Conversely, the natriuretic peptides have evolved under tremendous evolutionary constraints despite being encoded in tandem with helokinestatins by the same gene precursor. Of particular note is the sequencing for the first time of kunitz peptides from a lizard toxin-secreting gland. Not only are kunitz peptides shown to be an ancestral toxicoferan toxin, the ancestral state of this peptide is revealed to be a dual domain encoding precursor. This research provides insight into the evolutionary history of the ancient toxicoferan reptile venom system. In addition, it shows that even ‘clinically irrelevant’ Species can be a rich source of novel venom components, worthy of investigation for drug design and biomedical research.
