Brown is the new green: grassland responses to drought and heat. This project aims to improve accuracy and precision in predicting the impact of water availability and heat stress on grassland function. Grassland ecosystems are important reservoirs of global biodiversity and carbon storage. Grasslands are highly sensitive to drought and heat stress, but studies recently showed that current grassland models cannot predict these responses because they do not adequately represent the key processes ....Brown is the new green: grassland responses to drought and heat. This project aims to improve accuracy and precision in predicting the impact of water availability and heat stress on grassland function. Grassland ecosystems are important reservoirs of global biodiversity and carbon storage. Grasslands are highly sensitive to drought and heat stress, but studies recently showed that current grassland models cannot predict these responses because they do not adequately represent the key processes of physiological drought tolerance, leaf browning, and species traits. This project will collect targeted data sets in order to develop and test model representations of these key processes. This will provide significant benefits, such as greatly increasing capacity to predict the impact of drought and heat stress on grasslands, at scales ranging from field to globe.Read moreRead less

Summary
Tolerance of coralline algae to climate change in variable environments. This project aims to test whether organisms which regularly encounter low pH have greater tolerance to ocean acidification and why, and whether certain coralline algae can exert controls on their calcification that allows for greater tolerance to low pH. Coralline algae create and bind together reefs. Without them, both temperate and coral reefs as we know them would not exist. Understanding the extent to which tolerance to ....Tolerance of coralline algae to climate change in variable environments. This project aims to test whether organisms which regularly encounter low pH have greater tolerance to ocean acidification and why, and whether certain coralline algae can exert controls on their calcification that allows for greater tolerance to low pH. Coralline algae create and bind together reefs. Without them, both temperate and coral reefs as we know them would not exist. Understanding the extent to which tolerance to ocean acidification could be imparted to coralline algae through their environment or by physiological controls on calcification will enable us to better understand the fate of future reefs.Read moreRead less
