Organisms adapted to physiochemical stressors provide ideal systems to study evolutionary
mechanisms that drive adaptation and speciation. This review study focuses on livebearing …

Despite intensive ecotoxicological research, we still know relatively little about the
ecological impacts of many environmental contaminants. Filling these knowledge gaps is …

Natural environments vary, and organisms cope with this variation in two general ways: local
adaptation and phenotypic plasticity, although these strategies often overlap and interact …

The notorious plasticity of gene expression responses and the complexity of environmental
gradients complicate the identification of adaptive differences in gene regulation among …

The thermal ecology of ectotherm animals has gained considerable attention in the face of
human-induced climate change. Particularly in aquatic species, the experimental …

Natural selection drives the evolution of traits to optimize organismal performance, but
optimization of one aspect of performance can influence other aspects of performance. Here …

Convergent evolution in organismal function can arise from nonconvergent changes in traits
that contribute to that function. Theory predicts that low resource availability and high …

Populations that have recently diverged offer a powerful model for studying evolution.
Ecological differences are expected to generate divergent selection on multiple traits …

Sociality in animals depends on identification and recognition of conspecifics and social
interactions can be a key driving force in ecological processes. We capitalized on the …

Phenotypic variation is common along environmental gradients, but it is often not known to
what extent it results from genetic differentiation between populations or phenotypic …
