... that inhabit marine environments. There is therefore a demand for a framework through which to estimate energy expenditure from readily available data. We present the energetic costs associated with important time- and energy-intensive behaviours across nine families of marine bird (including seabirds, ducks...

... of warming temperatures on Arctic wildlife, leaving the importance of heat stress unclear. Here, we assessed the direct effects of increasing air temperatures on the physiology of thick-billed murres ( Uria lomvia ), an Arctic seabird with reported mortalities due to heat stress while nesting on sun-exposed...

...Manfred R. Enstipp; Charles-André Bost; Céline Le Bohec; Nicolas Chatelain; Henri Weimerskirch; Yves Handrich ABSTRACT The period of emancipation in seabirds, when juveniles change from a terrestrial existence to a life at sea, is associated with many challenges. Apart from finding favourable...

... can inform us about their potential resiliency to rapid environmental changes. Flexibility in maintaining energy balance is particularly important to long-lived, central-place foraging seabirds that are constrained when locating food for offspring in a dynamic ocean environment. To understand the role...

During two breeding seasons, small accelerometers were deployed on young (5 year old) and older (8/9 year old) brooding king penguins ( Aptenodytes...

...E. Pettex; F. Bonadonna; M. R. Enstipp; F. Siorat; D. Grémillet SUMMARY Seabirds, as other marine top predators, are often assumed to forage in an unpredictable environment. We challenge this concept and test the hypothesis that breeding Northern gannets (Morus bassanus) anticipate the spatio...
