Comparative study of the evolution of cancer gene duplications across fish

Evolutionary Applications, Volume 15, Issue 11, Page 1834-1845, November 2022., 2022
Abstract Comparative studies of cancer‐related genes not only provide novel information about their evolution and function but also an understanding of cancer as a driving force in biological systems and species’ life histories. So far, these studies have focused on mammals.

Roadkill patterns in Latin American birds and mammals

Global Ecology and Biogeography, Volume 31, Issue 9, Page 1756-1783, September 2022., 2022
Abstract Aim Roads are a major threat for wildlife, degrading habitat and causing mortality via wildlife–vehicle collisions. In Latin America, the conjunction of high biodiversity and a rapidly expanding road network is reason for concern. We introduce an approach that combines species traits and habitat preferences to describe vulnerability and map ...

A chromosome‐level genome of Antechinus flavipes provides a reference for an Australian marsupial genus with male death after mating

Molecular Ecology Resources, Volume 22, Issue 2, Page 740-754, February 2022., 2022
Abstract The 15 species of small carnivorous marsupials that comprise the genus Antechinus exhibit semelparity, a rare life‐history strategy in mammals where synchronized death occurs after one breeding season. Antechinus males, but not females, age rapidly (demonstrate organismal senescence) during the breeding season and show promise as new animal ...

Younger generations are more interested than older generations in having non-domesticated animals as pets

PLoS ONE, 2022
The trade and private ownership of non-domesticated animals has detrimental effects on individual animals and their wild populations. Therefore, there is a need to understand the conditions that motivate and dissuade interest in non-domesticated pet ...

Pesticide exposure on sloths (Bradypus variegatus and Choloepus hoffmanni) in an agricultural landscape of Northeastern Costa Rica.

Journal of environmental biology, 2014
Entre 2005 y 2008, se estudiaron Bradypus variegatus y Choloepus hoffmanni silvestres que habitaban un paisaje agrícola y animales cautivos de un centro de rescate en el noreste de Costa Rica para evaluar la exposición a plaguicidas. Se muestrearon un total de 54 animales: 42 perezosos silvestres capturados en un paisaje agrícola y 12 animales cautivos

A glance over the fence: Using phylogeny and species comparison for a better understanding of antigen recognition by human γδ T‐cells

Immunological Reviews, Volume 298, Issue 1, Page 218-236, November 2020., 2020
Abstract Both, jawless and jawed vertebrates possess three lymphocyte lineages defined by highly diverse antigen receptors: Two T‐cell‐ and one B‐cell‐like lineage. In both phylogenetic groups, the theoretically possible number of individual antigen receptor specificities can even outnumber that of lymphocytes of a whole organism.
