Cephalopods, especially squids, are believed to have a structuring role in marine
ecosystems as a link between different trophic levels, primarily due to their voracious prey …

This is the second volume of the entirely rewritten, revised and updated version of the
original FAO Catalogue of Cephalopods of the World (1984). The present Volume is a …

Stable carbon isotope signatures (δ 13 C) are increasingly being used to determine the
foraging habitats of consumers in the Southern Ocean. An underlying assumption is that a …

Stable isotope analyses and satellite telemetry were used to investigate the relationship
between the body size and feeding habitat of adult female loggerhead turtles Caretta caretta …

Green turtles Chelonia mydas are endangered, long-lived marine reptiles that display an
ontogenetic shift in diet and habitat use during development. During their early life stage …

Cephalopods play a key role in the marine environment but knowledge of their feeding
habits is limited by lack of data. Here, we have developed a new tool to investigate their …

Ecologists primarily use δ 15 N values to estimate the trophic level of organisms, while δ 13
C, and even recently δ 15 N, are utilized to delineate feeding habitats. However, many …

The trophic position and the predator-prey relationship between the sperm whale Physeter
macrocephalus and the jumbo squid Dosidicus gigas were examined by measuring stable …

Cephalopod movement occurs during all phases of the life history, with the abundance and
location of cephalopod populations strongly influenced by the prevalence and scale of their …

Cephalopods (Mollusca: Cephalopoda) play an important role as keystone invertebrates in
various marine ecosystems, as well as being a valuable fisheries resource. At the World …
