Black-legged kittiwakes (Rissa tridactyla) readily consume Arctic cod (Boreogadus saida) in the Canadian Arctic: insights from stomach content and stable isotope analyses

Arctic Science
The Arctic is undergoing rapid declines in sea ice and changes in Arctic ecosystems. The diet of one of the Arctic’s most abundant seabirds, the black-legged kittiwake (Rissa tridactyla), has been used as an indicator of ecosystem changes in the European

The Ensemble of Conformations of Antifreeze Glycoproteins (AFGP8): A Study Using Nuclear Magnetic Resonance Spectroscopy

Biomolecules, 2019
The primary sequence of antifreeze glycoproteins (AFGPs) is highly degenerate, consisting of multiple repeats of the same tripeptide, Ala−Ala−Thr*, in which Thr* is a glycosylated threonine with the disaccharide beta-d-galactosyl-(1,3)-alpha ...

Питание сайки Boreogadus saida в Беринговом и Чукотском морях

Известия ТИНРО (Тихоокеанского научно-исследовательского рыбохозяйственного центра), 2013
В осенний период сайка в Анадырском заливе питается в основном амфиподами и копеподами. У более крупных экземпляров амфиподы в рационе частично заменяются креветками. Так же как в Анадырском заливе, в Чукотском море сайка поедает в большом количестве амфипод, различных креветок и копепод.
