Whereas theories of ecological diversity mostly consider continuously supplied nutrients, a seasonal model uncovers a general mechanism that controls diversity and reconciles conflicting experimental findings.
Comprehensive genomic and population genetic analyses of a non-recombining chromosome in white-throated sparrows reveal the actions of purifying selection, positive selection, and balancing selection, expanding our understanding of supergene evolution.
Little Swifts dynamically adjust their foraging behavior to aerial insect abundance, revealing key insights into predator–prey interactions and optimal foraging strategies in aerial environments.
Granzyme A-/- mice, which have contributed to a body of research into this enzyme, emerge to have a mixed C57BL/6J-C57BL/6N genetic background, compromising our understanding of granzyme A and highlighting a widespread problem for knockout mouse studies generally.
Even moderate winds cause auks to abort landing attempts at nest-sites, and as a result, wind characteristics may affect where these, and other seabirds, choose to breed.
Contrary to the high absolute number of white-eyes in other parts of the world, the Indonesian archipelago is the center of phylogenetic diversity of this great speciator.

Ephemeral leadership between differently experienced birds regulates the balance between exploration and exploitation over successive homing flights in a manner that facilitates the accumulation of route innovations.
Spatial variations of transcription factor expression regulate the choice of progenitors to stay in their niche or to migrate into neural and mesodermal tissues.
