Low-density, selective grazers with restricted habitat requirements may be particularly vulnerable to extinction under hotter, drier conditions expected across Africa’s drylands with climate change. We evaluated how spatiotemporal variation in vegetation greenness and environmental heat load influenced movements of sable antelope, a water-dependent African grazer with selective resource requirements. We recorded hourly Global...

Many populations experience high seasonal temperatures. Pregnant women are considered vulnerable to extreme heat because ambient heat exposure has been linked to pregnancy complications including preterm birth and low birthweight. The physiological mechanisms that underpin these associations are poorly understood. We reviewed the existing research evidence to clarify the mechanisms that lead to adverse pregnancy outcomes in or...
