To understand evolutionary transformations it is necessary to identify the character states of
extinct ancestors. Ancestral character state reconstruction is inherently difficult because it …

We used mitochondrial DNA sequence data from 151 individuals to estimate population
genetic structure across the range of the Western Diamondback Rattlesnake (Crotalus …

Viviparity (live-bearing reproduction) is a widespread reproductive pattern of considerable
biological significance and a subject of intensive ongoing investigation. Viviparity in …

Long-term studies of individual animals in nature contribute disproportionately to our
understanding of the principles of ecology and evolution. Such field studies can benefit …

An understanding of spatial and thermal factors, two fundamentally intertwined elements, is
essential to the health and welfare of captive reptiles; carers cannot address one without …

Biodiversity elements with narrow niches and restricted distributions (ie,'short range

Predators must contend with numerous challenges to successfully find and subjugate prey.
Complex traits related to hunting are partially controlled by a large number of co‐evolved …

Urbanization can have significant consequences on local wildlife. While some species can
thrive in urban environments, others are often seen as nuisance animals and therefore are …

Human-induced global climate change is exerting increasingly strong selective pressures
on a myriad of fitness traits that affect organisms. These traits, in turn, are influenced by a …
