What shapes intraspecific genetic diversity in amphibians and reptiles? A comparative macrogenetic study across six biogeographic regions

Species distribution models predict genome-wide polymorphism and gene flow in an endangered amphibian.

Species distribution models (SDMs) are widely used to predict habitat suitability but their usefulness and accuracy for inferring population health is still debated. Here, we evaluate whether SDM-derived relative habitat suitability (RHS) predicts genome-wide genetic diversity and connectivity-which are key proxies for...

Demographic history, spatiotemporal genetic structure and climate vulnerability of Shorea robusta: a keystone species of moist deciduous forest in India

Influence of functional traits and trait syndromes on the vulnerability of amphibians and reptiles in the tropical dry forest of Oaxaca, Mexico

Tropical dry forests are among the most threatened ecosystems worldwide, yet their biodiversity remains understudied compared to humid tropical forests. We integrated functional trait ecology with environmental vulnerability assessments to evaluate multi‑causal disturbances affecting amphibians and reptiles in Oaxaca...

Exploring mitochondrial diversity in the species-rich genus Liolaemus: the interplay between isolation by distance and environmental thermal variability

Abstract Intraspecific genetic variation enhances a species´ capacity to endure diverse environments. Such variation can drive genetic divergence among populations, often manifesting as isolation by distance (IBD). Here, we investigated how ecological, environmental, life-history, body size, and phylogenetic factors sh...

Population genetic structure of a Colombian endemic poison frog Dendrobates truncatus (Anura: Dendrobatidae): A contribution to its conservation

The yellow-striped poison frog Dendrobates truncatus is endemic to Colombia. Despite its ecological plasticity and apparent abundance, which led to its classification as Least Concern (LC) on the IUCN Red List, it is crucial to objectively assess its conservation status, as the species faces significant threats from ha...

Connectivity, genetic diversity and adaptive potential of an endangered beetle: genomic evidence for veteran tree management

Habitat fragmentation and destruction in old-growth forests represents a primary threat to specialist species, frequently resulting in the erosion of genetic diversity. The Hermit Beetle, Osmoderma barnabita, is a protected relic of primeval forests and an obligate saproxylic specialist whose larval development depends...
