Behavior / reproduction / life cycle of krill as a marker of climate change in the Antarctic

Blagodurov Ilya Sergeevich

In recent years, the polar regions have received increasing scientific and public attention. interest. Both the Arctic and Antarctic are recognized as key regions in the regulation of the global climate and polar ecosystems are particularly susceptible to ongoing environmental changes. Ecology aims to advance scientific knowledge about the polar and subpolar regions of both hemispheres by facilitating the rapid and widespread dissemination of new scientific information from recent marine research, freshwater and terrestrial biota to polar researchers, environmental managers and policymakers. Krill is a high-latitude species of Antarctic macroplankton. The transfer of crustaceans to the north occurs with the western branches of the cyclones. How far it will go depends on the development of these circulation branches. The northern boundary of the massive krill drift is the Antarctic Secondary Frontal Zone. Removal from it can be considered sterile or non-sterile eviction. Some krill penetrate the shelves of some of the seas, thanks to currents associated with underwater troughs that cut the slope and shelf. Warm deep waters that penetrate into the shelf zone play an important role in this process. Consequently, it is necessary to significantly intensify international efforts in the field of polar research, and interaction between the scientific community of researchers at the North and South Poles.
