Estimating Long-Term Survival Temperatures at the Assemblage Level in the Marine Environment: Towards
Defining ecologically relevant upper temperature limits of species is important in the context of environmental change. The approach used in the present paper estimates the relationship between rates of temperature change and upper temperature limits for survival in order to evaluate the maximum lon...
