Integrative Zoology, EarlyView.We decode mitochondrial genomes across all extant canids, revealing lineage‐specific codon optimization driven by altitude, predation, and body size. A tripartite framework integrates geological events, metabolic constraints, and adaptive radiation to explain carnivore evolution.

Impact of global change on the distribution of mountain mammals and birds
Conservation Biology, EarlyView.Abstract Climate change and land‐use changes are key drivers of global biodiversity loss. Many species are shifting to higher elevations or latitudes in response to global warming, often encountering unfavorable land‐use conditions during the shift. These changes can lead to reduced range size and increased extinction risks, particularly for mountain ...

Zoologica Scripta, EarlyView.ABSTRACT Three forested dispersal corridors have been proposed within the diagonal of open/dry landscapes in South America and the relative importance of each one has been the subject of debate for forest organisms. We analysed the biogeographical history of three snake genera (Bothrops, Philodryas, and Micrurus) from different families (Viperidae ...

The Journal of Physiology, EarlyView.Abstract figure legend In lowland mammals that ascend to high elevation, hypoxia‐induced changes in the pulmonary circulation can give rise to hypoxic pulmonary hypertension (HPH) and associated right‐ventricle (RV) hypertrophy. Andean mice with broad elevational ranges have greater heart mass relative to body size at higher elevations, but they ...

Modeling climate adaptive habitat connectivity for conservation planning in Colombia
Ecography, Volume 2026, Issue 10, October 2026.To remain effective under global change, conservation decisions must anticipate shifting climates, species responses to climate change and the dispersal pathways needed to track suitable climate. Yet most assessments of ecological connectivity do not consider how the landscape will change, or, if they do, they only consider a single future time point ...
