Abstract The Risso's dolphin, Grampus griseus, is a deep‐sea cetacean with a
predominantly teuthophagous diet. Its distribution in the northwest Mediterranean is …

This paper provides a summary of 25 years of research on Risso's dolphins (Grampus
griseus) in the western Ligurian Sea. Seasonal variations in abundance, distribution and …

Introduction Conservation of cetaceans is challenging due to their large-range, highly-
dynamic nature. The EU Habitats Directive (HD) reports 78% of species in …

Relatively scant information is available on the Risso's dolphin in comparison to the other
species regularly present in the Mediterranean Sea. Recently, its conservation status has …

Marine traffic has been identified as a serious threat to Mediterranean cetaceans with few
mitigation strategies in place. With only limited research effort within the Eastern Basin …

The residency pattern and site fidelity of Risso's dolphin Grampus griseus were studied
using sightings data collected during standardized vessel-based surveys carried out from …

The Risso's dolphin is a widely distributed species, found in deep temperate and tropical
waters. Estimates of its abundance are available in a few regions, details of its distribution …

Photo-identification is one of the best practices to estimate the abundance of cetaceans and,
as such, it can help to obtain the biological information necessary to decision-making and …

Photo-identification is a commonly used non-invasive technique that has been profitably
employed in biological studies throughout the years. It starts from the assumption that a …

Deep-habitat cetaceans are generally difficult to study, leading to a limited knowledge of
their population. This paper assesses the differential distribution patterns of three deep …
