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 ...

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.

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 ...

Journal of Applied Ecology, Volume 62, Issue 6, Page 1392-1405, June 2025.Due to their higher performance and reliability, we consider SSDMs valuable for modelling unobserved discards and advise caution when using conditional joint prediction for continuous response variables such as biomass, especially when overdispersion is likely.

Brazilian Archives of Biology and Technology, 1998 This work characterizes the composition of Brachyura from Schizoporella unicornis. The samples were collected in 1995 at Itaguá Beach, Ubatuba (SP), at three month intervals, during all seasons from January to December. The Bryozoa colonies were obtained

Ethology, Volume 131, Issue 5, May 2025.ABSTRACT In the Indo‐West Pacific biogeographical region, a suite of shorebirds searches for crabs as food. While the majority of these shorebirds hunt on burrowing crabs, the endemic crab plover Dromas ardeola additionally feeds on swimming crabs with “fast and powerful claws”.
