Biochemistry and Biophysics Reports, 2020 Chitin is an organic polymer and it is the most frequent marine natural polysaccharide after cellulose. The main natural sources of chitin are exoskeletons of insects, mollusks, the cell walls of certain fungi and crustaceans such as crabs, shrimps and lobsters.

Century‐Scale Changes in the Feeding Patterns of Demersal Fish Species in the Western North Sea
Fish and Fisheries, Volume 27, Issue 2, Page 99-115, March 2026.ABSTRACT Understanding the extent and magnitude of change in marine food webs requires historical data that predates modern monitoring efforts. Such information can provide invaluable insights into the longer‐term impacts of altered trophic interactions, yet it is rarely incorporated into marine policy frameworks.

A Comparison of DNA Metabarcoding Cloacal Swabs and Stomach Contents for Shark Diet Reconstruction
Environmental DNA, Volume 8, Issue 1, January–February 2026.Our results indicate that the less invasive, non‐lethal method of DNA metabarcoding cloacal swabs provided higher taxonomic resolution than more common methods for studying shark trophic ecology (i.e., morphological stomach contents identification and trophic biomarkers) with no statistical difference in overall diet description between cloacal swabs ...

Assessment of a Social Media‐Based Method for Determining Raptor Diet
Ecology and Evolution, Volume 15, Issue 6, June 2025.This study mined social media as a citizen science method to reduce the time burden and biases associated with recording accurate diet information for predators. In total, 1985 prey observations were recorded of two Australian coastal raptors and were used to produce diet profiles that were compared by region, social media platform, and against other ...

Ecology and Evolution, Volume 15, Issue 6, June 2025.This study, through a combination of morphological analysis, molecular identification, and stable isotope analysis, confirmed that crustaceans are the primary food source for these fishes. Small carnivorous fishes reduce niche overlap by selectively feeding on different types of crustaceans—a strategy supported by the abundant crustacean resources in ...
