Climate change is dramatically altering our planet, yet our understanding of mechanisms of
thermal tolerance is limited in wild birds. We characterized natural variation in heat shock …

Abstract The southeastern United States is a hotspot of biodiversity, but aquatic habitats are
fragmented by anthropogenic activities such as hydrologic alteration. Small-stream …

The influence of environment and phylogeny on morphological characteristics of organisms
is well documented. However, little is known about how these factors influence scale shape …

Variation in physiological traits can influence the relative resilience of individuals,
populations and species of fish to environmental change. Thus, understanding the extent …

Researchers studying nonmodel organisms have an increasing number of methods
available for generating genomic data. However, the applicability of different methods …

Geographic isolation is the primary driver of speciation in many vertebrate lineages. This
trend is exemplified by North American darters, a clade of freshwater fishes where nearly all …

Managers and researchers have taken an increasing interest in Alligator gar (Atractosteus
spatula). Conservation efforts are needed across much of the range where there are either …

Simple Summary Schizothorax kozlovi Nikolsky is a unique cold− water fish in the upper
reaches of the Yangtze River in China and has high economic value. In our study, genetic …

The southeastern US is a hotspot of aquatic biodiversity and endemism in the upland and
Coastal Plain regions. One component of this biodiversity is the Pygmy Sunfishes of the …

Intensifying heat waves pose widespread challenges to many animals. Previous work,
largely in wild ectotherms or agricultural endotherms, has established that heat induces …
