The physiological dependence of animals on dietary intake of vitamins, amino acids, and
fatty acids is ubiquitous. Sharp differences in the availability of these vital dietary …

Abstract The Ebro Delta has become a major blue crab (Callinectes sapidus) fishery area in
the NW Mediterranean, but there is limited information on factors controlling the abundance …

Species performance depends on the concerted interplay of their functional traits. Natural
selection acts on the performance of the species and influences entire suits of …

Many traits including trophic niche parameters are attributed to species. However, generalist
species may vary in trophic niches with environments, making species‐based knowledge …

Eco-evolutionary theory has brought an interest in the rapid evolution of functional traits.
Among them, diet is an important determinant of ecosystem structure, affecting food web …

The diet of an individual is a result of the availability of dietary items and the individual's
foraging skills and preferences. Behavioural differences may thus influence diet variation …

Fishing has significant trophodynamic impacts on marine communities, including reductions
in the mean trophic position (TP) of the ecosystem resulting from a decrease in the …

Aim The relationship between body size and trophic position (BS–TP) typically exhibits a
positive correlation in aquatic foodwebs, but the strength of this relationship is contingent on …

Understanding consumer–resource interactions is essential for understanding the trophic
dynamics of species-rich fish communities. Woodland et al.(Oikos 125: 556–565, 2016) …

Although many upstream effects of a dam on the trophic ecology of fish have been reported,
little is known about their downstream effects on the isotopic niche of Amazonian predator …
