American Journal of Botany, EarlyView.Abstract Premise Understanding how plant populations adapt to water limitation through stomatal traits is key to predicting drought responses. The dominant C4 grass Andropogon gerardi, distributed across sharp climate gradients in North America, offers an excellent focal species to study stomatal architecture (size and density).

The Anatomical Record, EarlyView.Analysis of cranial endocast data of 181 extant and 41 fossil species from Euarchontoglires shows that there was a reduction in olfactory bulb size in Crown Primates, but that there were also subsequent reductions in various other primate clades (Anthropoidea, Catarrhini, Platyrrhini, crown Cercopithecoidea, Hominoidea).
