Among the most common statements made in studies of elasmobranch ecology is
something to the effect that “sharks play an important role in marine ecosystems.” Although …

Rays (superorder Batoidea) are the most diverse group of elasmobranchs, and many are
threatened with extinction. However, there remain areas where research on the ecology of …

Abstract The big (Raja binoculata), California (R. inornata), longnose (R. rhina), and
sandpaper (Bathyraja kincaidii), skates are commonly found on soft-bottom regions of the …

Predator–prey interactions play a central role in the behavior, ecology, and population
biology of most taxa and are critical in community dynamics. For elasmobranchs, most …

Using a bioenergetic and allometric approach, we developed multispecies trophodynamic
models of the marine community of northern and central Patagonia in the southwestern …

The ontogenetic changes in the diet and dietary overlap of three commercially important
rajid species inhabiting the slope and shelf waters of the Falkland Islands were investigated …

Landings of batoids (rays and skates) have been rising in Argentina, reaching 14856mt in
1998. These species are poorly known, and their low fecundity, late maturity and slow …

The age and growth parameters of Dipturus chilensis were estimated by counting growth
rings from thin sections of vertebral centra from 400 fish (246 females and 154 males) …

In this study, fishes and invertebrates collected from the continental slope (1000 m) of the
eastern North Pacific Ocean were analysed using stable‐isotope analysis (SIA). Resulting …

Understanding the variation in the diet of skates is crucial for determining their roles in
marine ecosystems. The diet of 458 sandskates, Psammobatis extenta, from Puerto …
