Ecology Letters (2010) 13: 1055–1071 Abstract Whereas many land predators disappeared
before their ecological roles were studied, the decline of marine apex predators is still …

Recent studies document unprecedented declines in marine top predators that can initiate
trophic cascades. Predicting the wider ecological consequences of these declines requires …

Elasmobranchs (sharks, rays and skates) are among the most threatened marine
vertebrates, yet their global functional diversity remains largely unknown. Here, we use a …

Measures of trophic position (TP) are critical for understanding food web interactions and
human‐mediated ecosystem disturbance. Nitrogen stable isotopes (δ15N) provide a …

Ocean noise pollution is of special concern for cetaceans, as they are highly dependent on
sound as their principal sense. Sound travels very efficiently underwater, so the potential …

Apex predators are often assumed to be dietary generalists and, by feeding on prey from
multiple basal nutrient sources, serve to couple discrete food webs. But there is increasing …

As marine aquaculture expands around the world, there is increased concern for impacts to
protected species. Documented cases of marine mammal, sea turtle, seabird, and shark …

Stable‐isotope analysis (SIA) can act as a powerful ecological tracer with which to examine
diet, trophic position and movement, as well as more complex questions pertaining to …

This study analyzes microplastic ingestion by three deep-water elasmobranch species
(Galeus melastomus, Scyliorhinus canicula and Etmopterus spinax) from the Tyrrhenian …

Understanding the trophic interactions and the position of species within a foodweb is
crucial if we want to understand the dynamics of marine communities and the impact …
