Quantitative fatty acid signature analysis: A new method of estimating predator diets
(2004-05)
Accurate estimates of the diets of predators are required in many areas of ecology, but for many
species current methods are imprecise, limited to the last meal, and often biased. The diversity of
fatty acids and their ...
Seasonal changes in buoyancy and diving behaviour of adult grey seals
(2000-08)
Phocid seals go through dramatic seasonal changes in body mass and composition as a result of
the spatial and temporal separation of foraging, reproduction and moulting. These changes in body
fat content and body mass ...
Linking movement, diving, and habitat to foraging success in a large marine predator
(2006-12)
Establishing where and when predators forage is essential to understanding trophic interactions,
yet foraging behavior remains poorly understood in large marine carnivores. We investigated the
factors leading to foraging ...
Body condition at weaning affects the duration of the postweaning fast in gray seal pups (Halichoerus grypus)
(2008-05)
Gray seals (Halichoerus grypus) undergo a terrestrial postweaning fast (PWF) that depletes
energy reserves acquired during the suckling interval. Plasticity in PWF duration may ensure that
pups of variable body condition ...
