Understanding the mechanisms that drive prey selection is a major challenge in foraging ecology. Most studies of strategies have focused on behavioural costs, and generally failed to recognize differences quality may be as important predators costs acquisition. Here, we tested whether there relationship between diets (kJ·g−1) consumed by cetaceans North Atlantic their metabolic living estimated indicators muscle performance (mitochondrial density, n = 60, lipid content, 37). We found cost 11...
During ontogeny, the increase in body size forces species to make trade-offs between their food requirements, conditions necessary for growth and reproduction as well avoidance of predators. Ontogenetic changes are leading seek out habitats resources that meet needs. To this end, ontogenetic nocturnal habitat (vertical use water column) type (based on stable isotopes nitrogen) were investigated 12 deep pelagic fish from Bay Biscay Northeast Atlantic. Our results revealed existence major...
Abstract Spitz, J., Mourocq, E., Schoen, V., and Ridoux, V. 2010. Proximate composition energy content of forage species from the Bay Biscay: high- or low-quality food? – ICES Journal Marine Science, 67: 909–915. Collapses high-energy dense concentrations prey induce negative effects on populations top predators. Knowledge quality appears to be crucial in ecosystem modelling management. The aim here was provide baseline data Biscay. (water, ash, protein, lipid) have been determined assess 78...
Abstract The short‐beaked common dolphin, Delphinus delphis , is abundant in both neritic and oceanic habitats. These two domains differ largely terms of the nature forage organisms their availability to surface‐bound top predators, which suggests that dolphin should show extensive variability foraging strategies as a response these different However, although its diet well known over continental shelves, so far, mostly because sampling issues, nothing has been published on In this study,...

Summary Understanding ‘Why a prey is for given predator?’ can be facilitated through trait‐based approaches that identify linkages between and predator morphological ecological characteristics highlight key functions involved in selection. Enhanced understanding of the functional relationships predators their now essential to go beyond traditional taxonomic framework dietary studies improve our knowledge ecosystem functioning wildlife conservation management. We test relevance three‐matrix...
Defecation by large whales is known to fertilise oceans with nutrients, stimulating phytoplankton and ecosystem productivity. However, our current understanding of these processes limited a few species, nutrients ecosystems. Here, we investigate the role cetacean communities in worldwide biological cycling two major six trace nutrients. We show that cetaceans release more mesotrophic eutrophic temperate waters than oligotrophic tropical waters, mirroring patterns The released nutrient...
Although deep-sea cephalopods are key marine organims, their feeding ecology remains essentially unknown. Here, we report for the first time trophic structure of an assemblage these animals (19 species) by measuring isotopic signature wings lower beaks, which accumulated in stomachs stranded sperm whales. Overall, species encompassed a narrow range δ 13 C values (1.7‰), indicating that they lived closely related and overlapping habitats. can be interpreted terms distribution with more...

Environmental conditions can shape genetic and morphological divergence. Release of new habitats during historical environmental changes was a major driver evolutionary diversification. Here, forces shaping population structure ecotype differentiation ('pelagic' 'coastal') bottlenose dolphins in the North-east Atlantic were investigated using complementary ecological approaches.

Knowledge of relationships between predator size and prey are needed to describe interactions species classes in food webs. Most estimates sizes have been based on dietary studies apply small numbers a relatively narrow range. These may or not be representative values for other groups body locations. Marine data associated with published literature were identified collated produce single set. If length mass measured the original study, was calculated using length–mass relationships. The set...
