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

Hydrogen sulfide (H2S) is a respiratory toxicant that creates extreme environments tolerated
by few organisms. H2S is also produced endogenously by metazoans and plays a role in …

The concept of a “speciation continuum” has gained popularity in recent decades. It
emphasizes speciation as a continuous process that may be studied by comparing …

Evidence of phenotypic parallelism is often used to infer the deterministic role played by
natural selection. However, variation in the extent or direction of divergence is often evident …

The comprehensive assessment of the long-term impacts of constant exposure to pollutants
on wildlife populations remains a relatively unexplored area of ecological risk assessment …

Hydrogen sulfide is a toxic gas that disrupts numerous biological processes, including
energy production in the mitochondria, yet fish in the Poecilia mexicana species complex …

One century after their introduction to Europe, eastern mosquitofish (Gambusia holbrooki)
represent a natural experiment to determine the relative contributions of adaptive plasticity …

Reductions in a limiting nutrient might be expected to necessitate compromises in the
functional traits that depend on that nutrient; yet populations existing in locations with low …

Mitochondria have been known to be involved in speciation through the generation of
Dobzhansky–Muller incompatibilities, where functionally neutral co-evolution between …

Hydrogen sulfide (H2S) is a natural toxicant in some aquatic environments that has diverse
molecular targets. It binds to oxygen transport proteins, rendering them non-functional by …
