Aerobic metabolism in eukaryotic cells requires extensive interactions between products of
the nuclear and mitochondrial genomes. Rapid evolution of the mitochondrial genome …

ABSTRACT A major goal of evolutionary science is to understand how biological diversity is
generated and altered. Despite considerable advances, we still have limited insight into how …

Groups of animals can perform highly coordinated collective behaviours that confer benefits
to the participating individuals by facilitating social information exchange and protection from …

Environmental factors can promote phenotypic variation through alterations in the
epigenome and facilitate adaptation of an organism to the environment. Although hydrogen …

The collective behavior of animals has attracted considerable attention in recent years, with
many studies exploring how local interactions between individuals can give rise to global …

Extreme environments test the limits of life; yet, some organisms thrive in harsh conditions.
Extremophile lineages inspire questions about how organisms can tolerate physiochemical …

Regulating transcription allows organisms to respond to their environment, both within a
single generation (plasticity) and across generations (adaptation). We examined …

The generation of variation is paramount for the action of natural selection. Although
biologists are now moving beyond the idea that random mutation provides the sole source of …

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 …

Our understanding of the mechanisms mediating the resilience of organisms to
environmental change remains lacking. Heavy metals negatively affect processes at all …
