Ecography, Volume 2025, Issue 5, May 2025.Food‐webs are a major component of ecosystems and determinant for their functioning and structure. The food chain length (FCL) is a key feature of food‐webs and it is crucial for the resistance of the community to external stressors. The Southern Ocean (SO) food‐web is known for being short and dominated by an Antarctic krill Euphausia superba surplus,

Trophic ecology of groundfishes in nearshore areas of the Gulf of Maine
Journal of Fish Biology, Volume 106, Issue 4, Page 1095-1111, April 2025.Abstract Ecosystem management requires an integrated understanding of ecological interactions. In the Gulf of Maine (GoM), trophic information pertaining to commercially important groundfishes and nearshore prey communities is lacking. We characterized nearshore communities and groundfish diets using data collected from nearshore surveys (864 bottom ...
