The migratory woodland caribou refers to two herds of Rangifer tarandus (known as caribou in North America) that are included in the migratory woodland ecotype of the subspecies Rangifer tarandus caribou or woodland caribou [1] [2] that live in Nunavik, Quebec, and Labrador: the Leaf River caribou herd (LRCH) [3] [4] and the George River caribou herd (GRCH) south of Ungava Bay.
The sea surface microlayer (SML) at the air-sea interface is a distinct, under-studied habitat compared to the subsurface and copepods, important components of ocean food webs, have developed key adaptations to exploit this niche. [40] The ocean-spanning SML forms the boundary between the atmosphere and the hydrosphere.
The ocean's surface acts like a skin between the atmosphere above and the water below, and harbours an ecosystem unique to this environment. This sun-drenched habitat can be defined as roughly one metre in depth, as nearly half of UV-B is attenuated within this first meter. [ 29 ]
Caribou are still hunted in Greenland and in North America. In the traditional lifestyles of some of Canada's Inuit peoples and northern First Nations peoples, Alaska Natives, and the Kalaallit of Greenland, caribou is an important source of food, clothing, shelter and tools.

Marine life, sea life or ocean life is the collective ecological communities that encompass all aquatic animals, plants, algae, fungi, protists, single-celled microorganisms and associated viruses living in the saline water of marine habitats, either the sea water of marginal seas and oceans, or the brackish water of coastal wetlands, lagoons ...
The caribou, which is a species of deer, are also extremely abundant in this region. Caribou primarily feed on lichens, moss, grasses, and birches. [20] Many people consider them to be a keystone species due to the amount of other animals, mostly carnivores that depend on the caribou as a primary food source.
The ocean represents the largest continuous planetary ecosystem, hosting an enormous variety of organisms, which include microscopic biota such as unicellular eukaryotes (protists). Despite their small size, protists play key roles in marine biogeochemical cycles and harbour tremendous evolutionary diversity.
An ecosystem is composed of biotic communities that are structured by biological interactions and abiotic environmental factors. Some of the important abiotic environmental factors of aquatic ecosystems include substrate type, water depth, nutrient levels, temperature, salinity, and flow.
