SUMMARY:Estimating acclimation temperatures at the assemblage level in the
  marine environment: towards macrophysiology - Dr Joelle Richard (British 
 Antarctic Survey)

DESCRIPTION:Defining ecologically relevant upper temperature limits of spe
 cies is important in the context of environmental change. The approach use
 d here is to draw the relationship between rates of temperature change and
  upper temperature limits in order to evaluate the maximum acclimation tem
 perature and to calculate a new index: the excess acclimatory capacity (EA
 C). This index is defined as the maximum environmental temperature increas
 e which organisms in a given environment can cope with. It provides a meas
 ure of how close a species/ assemblage/ fauna are to their limits and henc
 e their vulnerability to environmental warming. The method applied here\, 
 relating temperature limits to rate of experimental warming\, has potentia
 l for wide application in the identification of faunas with little excess 
 acclimatory capacity to survive environmental warming.
