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 …

Many elasmobranch species are undergoing population declines on a global scale;
however, implementation of effective conservation and management strategies is hindered …

1. Understanding how natural and anthropogenic drivers affect extant food webs is critical to
predicting the impacts of climate change and habitat alterations on ecosystem dynamics. 2 …

The reproductive diversity of extant cartilaginous fishes (class Chondrichthyes) is
extraordinarily broad, reflecting more than 400 million years of evolutionary history. Among …

Given the known effect of lipid content on δ13C values and the potential effect of urea on
δ15N values, examining the effects of lipid extraction, which can potentially extract both, is of …

Changes in feeding habits during ontogeny show that organisms can present shifts in
foraging behavior during their life cycle, which can alter local trophic dynamics. Therefore …

Deep-sea chondrichthyans are cryptic species subject to increasing anthropogenic
exploitation. Defining their role in deep-water ecosystems is therefore crucial for predicting …

Abstract The Cookiecutter shark (Isistius brasiliensis) is an ectoparasitic, mesopelagic shark
that is known for removing plugs of tissue from larger prey, including teleosts …

White sharks Carcharodon carcharias and shortfin mako sharks Isurus oxyrinchus are
globally distributed apex predators and keystone species. However, regional information …

Stable isotopes are often used to determine the ecological role of different age classes of
animals, but particularly for young animals this approach may be compromised. During …
