Impacts of river fragmentation on limiting individual dietary specialization of Amazonian predatory fish [PDF]

PeerJ, 2022
Individual dietary specialization is one of the factors that promotes variation in resource use at the individual level. Here we used stable isotope analysis of multiple tissues with different turnover rates to examine the degree of individual ...

Immunohistochemical Profile of a Conspicuously Organized Structure in the Dorsal Forebrain of the Peacock Gudgeon, Tateurndina ocellicauda. [PDF]

J Comp Neurol
In the dorsal telencephalon of gobiiform fishes, there is a conspicuously organized structure, consisting of readily identifiable subregions that are surrounded by layers of cell bodies. Using immunohistochemistry against several antigen targets in this structure, we demonstrate that each of these subregions is characterized by its own individual ...

Development of a non-lethal stomach content analysis method for freshwater eels: An empirical evaluation of the tube method for Anguilla marmorata. [PDF]

J Fish Biol
Abstract Understanding the feeding habits of predatory fish is essential for unravelling food web structures and implementing conservation strategies in riverine ecosystems. However, conventional lethal stomach content analysis methods are not necessarily appropriate for long‐term dietary studies, particularly for threatened species, as they require ...
