Studies on the feeding ecology of fish are essential for exploring and contrasting trophic
interactions and population and community dynamics within and among aquatic …

Recent studies have shown that coastal and shelf cephalopod populations have increased
globally over the last six decades. Although cephalopod landings are dominated by the …

Among the most common statements made in studies of elasmobranch ecology is
something to the effect that “sharks play an important role in marine ecosystems.” Although …

Comparisons of fish trophic data are limited by the range of methods used to quantify dietary
composition, with scientists yet to agree on a standard approach to stomach content …

Habitat use and selection influence population dynamics, interspecific and intraspecific
interactions, ecosystem structure, and biodiversity (Morris 2003). Ontogenetic shifts in …

Three-dimensional static equilibrium analysis of the forces generated by the jaw
musculature of the horn shark Heterodontus francisci was used to theoretically estimate the …

To make a first approach in the assessment of the sea urchin predators in the Azores, the
diet of white seabream (Diplodus sargus) and ballan wrasse (Labrus bergylta), were studied …

Dietary descriptions based on stomach content are pervasive regardless of the biases
concerning its methodology, statistics and descriptors. We here review different biases on …

In addition to the selective importance of interspecific morphological variation, ontogenetic
morphological variation may reflect different selective regimes to which successive …

Ontogenetic changes in habitat are driven by shifting life-history requirements and play an
important role in population dynamics. However, large portions of the life history of many …
