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

Angel sharks (Squatina spp.) are distributed in warm temperate to tropical waters around the
world. Many species occur in shelf seas and exhibit seasonal inshore–offshore migrations …

Food partitioning between species is a common strategy for avoiding resource competition
which allows the coexistence of two or more species in the same place. In order to evaluate …

Modern sharks have an evolutionary history of at least 250 million years and are known to
play key roles in marine systems, from controlling prey populations to connecting habitats …

The present study has tested statistically the hypothesis that the diets of four abundant and
co-occurring elasmobranch species differ and change with body size and season and has …

1. Introduction 2. Feeding Habits of Elasmobranchs 2.1. Techniques for Studying
Elasmobranch Diets 2.2. Elasmobranch Diet Composition and Dietary Shifts 2.3. Food …

Reef sharks may be ecologically redundant, such that other mesopredatory fishes
compensate for their functions when they decline in number, preventing trophic cascades …

Two species of angel shark (Squatina australis, S. albipunctata) and two species of
sawshark (Pristiophorus nudipinnis, P. cirratus) are frequently caught in south-eastern …

The feeding habits of the Rio skate, Rioraja agassizi, from off Uruguay and north Argentina
were evaluated using a multiple-hypothesis modelling approach. Relationships between …

Abstract Knowledge on the trophic ecology of elasmobranch species in all their size classes
is important to determine complex trophic roles and relationships between members of the …
