DESCRIPTION:Understanding the factors affecting the population dynamics of
  seabirds is essential to better inform conservation strategies\, but the 
 inherent complexity of ecosystems makes the identification of the mechanis
 ms underlying population dynamics difficult. Predicting future environment
 al impacts is an even greater challenge. We present a multi-faceted modell
 ing approach to capture the linkages between physiology\, behaviour\, and 
 the environment that rests on Dynamic Energy Budget theory and state depen
 dent foraging theory. This allows us to explore how growth\, maturation an
 d reproduction depend on the acquisition and allocation of energy under di
 fferent foraging strategies and environmental conditions. The models are p
 arameterized from\, and validated against\, extensive data on albatrosses 
 obtained by the British Antarctic Survey over the past decades.
