Alaska Food Web Research. A key area of fisheries and ecosystem research is collecting and analyzing data about food chains in the North Pacific. Data are put into environmental assessments, and single-species and multispecies models so we can better understand the relationships between organisms, and to their physical surroundings. Alaska.
Deep corals are widespread throughout Alaska, including the continental shelf and upper slope of the Gulf of Alaska, the Aleutian Islands, the eastern Bering Sea, and extending as far north as the Beaufort Sea. Coral distribution, abundance and species assemblages differ among geographic regions.
In the summer of 2022, researchers embarked on expeditions to survey, sample, and map deep-sea coral and sponge ecosystems in Alaska’s waters. This fieldwork is complemented by a series of smaller targeted research projects, ranging from environmental DNA studies of fish and corals, to refining estimates of longline and pot fishing gear ...
31 Αυγ 2021 · Coastal Alaskan lagoons were characterized by long food chains. •. Importance of terrestrial organic matter varied by foraging ecology and location. •. Subsistence target fishes relied on terrestrial organic matter-based food webs. Abstract.
The Alaska region is made up of 5 distinct ecosystems: the Gulf of Alaska (GOA), Aleutian Islands (AI), Eastern Bering Sea (EBS), Beaufort Sea, and the Chukchi Sea (Alaskan Arctic).
5 Ιουλ 2023 · In colder oceans, especially in high latitudes and arctic regions, animals throughout the food chain, from zooplankton to whales, produce or accumulate lipids to store energy for future use when food is less plentiful or absent.
Six food chain examples for forest, tundra, wetland, and ocean are shown in bold letters. Make food webs by using the other foods of each living thing (listed in small letters below its name) to find other interconnections.
