The development of the isotopic niche, an n-dimensional hypervolume (with n being the
number of isotopes) occupied by a population in delta space, has revolutionized the study of …

Coral reef ecosystems are exceptionally complex with a myriad of trophic pathways and
consumer relationships. The application of stable isotopes (SIs) offers numerous …

Assessing the foraging ecology of a threatened species is necessary to understand their
movement behaviour and habitat use patterns, which are essential for developing effective …

Great hammerhead sharks Sphyrna mokarran are the largest member of Sphyrnidae, yet the
roles of these large sharks in the food webs of coastal ecosystems are still poorly …

The bull shark (Carcharhinus leucas Valenciennes, 1839) is a large, primarily coastally
distributed shark famous for its ability to penetrate far into freshwater bodies in tropical …

Abstract 548 shark species were considered in this paper. They were classified in function of
their depth of occurrence: 218 deep, 114 transitory and 210 shallow. The diets of the 332 …

Nitrogen stable isotopes (δ15N) are typically used to estimate trophic position, providing
insight into ecological roles and broader food web structure. Ecological inferences drawn …

Nitrogen isotope (δ15N) analysis of bulk tissues and individual amino acids (AA) can be
used to assess how consumers maintain nitrogen balance with broad implications for …

Elasmobranchs are among the species most threatened by overfishing and a large body of
evidence reports their decline around the world. As they are large predators occupying the …

Recent studies have uncovered mosaic patterns of allometric and isometric growth
underlying ontogenetic shifts in the body form of elasmobranch species (shark and rays). It is …
