With climate change, habitat salinity is shifting rapidly throughout the globe. In addition,
many destructive freshwater invaders are recent immigrants from saline habitats. Recently …

Phenotypic plasticity is not universally adaptive. In certain cases, plasticity can result in
phenotypic shifts that reduce fitness relative to the un-induced state. A common cause of …

Approaches to macroevolution require integration of its two fundamental components, ie the
origin and the sorting of variation, in a hierarchical framework. Macroevolution occurs in …

Highly fecund marine species with dispersive life-history stages often display large
population sizes and wide geographic distribution ranges. Consequently, they are expected …

Differential natural selection acting on populations in contrasting environments often results
in adaptive divergence in multivariate phenotypes. Multivariate trait divergence across …

Many morphological, behavioral, physiological, and life-history traits covary across the
biological scales of individuals, populations, and species. However, the processes that …

Understanding the genetic basis of traits involved in adaptation is a major challenge in
evolutionary biology but remains poorly understood. Here, we use genome-wide association …

Ecological divergence is a fundamental source of phenotypic diversity between closely
related species, yet the genetic architecture of most ecologically relevant traits is poorly …

If genetic architectures of various quantitative traits are similar, as studies on model
organisms suggest, comparable selection pressures should produce similar molecular …

Background In addition to additive genetic effects, epistatic interactions can play key roles in
the control of phenotypic variation of traits of interest. In the current study, 475 male birds …
