The paper analyzes mitochondrial and nuclear DNA sequences of Kashmir voles to revise their taxonomy and phylogenetic placement within the arvicoline family.

This study investigates the molecular mechanisms of alkaloid sequestration in poison frogs by analyzing serpin gene family evolution and liver gene expression.

This study shows that undefended poison frogs accumulate low levels of alkaloids from their diet, suggesting passive accumulation as an intermediate step in the evolution of chemical defenses.
