Effects of some antiseptics on rate of Antarctic krill autoproteolysis [PDF]

Acta Ichthyologica et Piscatoria, 1981
Intensity of autoproteolysis in Antarctic krill (Euphausia superba) in the presence of some antiseptics was studied. The rate of autoproteolysis was assessed from release of amino and non-protein nitrogen in 100 g raw protein.

Molecular Diet Analysis of Adélie Penguins (Pygoscelis adeliae) in the Ross Sea Using Fecal DNA

Biology, 2022
The diet of Adélie penguins, Pygoscelis adeliae, is a useful indicator in understanding the ecological conditions of their habitats. The diets of Adélie penguins were studied using metabarcoding and quantitative PCR (qPCR) analyses of fecal DNA from ...
