Positive selection drives the evolution of a primate bitter taste receptor gene

Ecology and Evolution, 2021
Bitter taste perception is important in food choice of animals, and it is mediated by bitter taste receptor (T2R) containing three regions: extracellular regions (ECs), transmembrane regions (TMs), and intracellular regions (ICs). It is hypothesized that

Rare species perform worse than widespread species under changed climate [PDF]

, 2020
Predicting how species, particularly rare and endangered ones, will react to climate change is a major current challenge in ecology. Rare species are expected to have a narrower niche width than more widespread species.
