One of the most important is an increase in ocean temperatures. More frequent marine heatwaves are linked to this. The rising temperature contributes to a rise in sea levels due to the expansion of water as it warms and the melting of ice sheets on land.
Video of Porcupine caribou in Becharof National Wildlife Refuge, Alaska. Ivvavik National Park protects a portion of the calving grounds of the Porcupine herd and restricts the number of people who may visit annually. During the calving in May, caribou are at their most vulnerable. Caribou management calls for preservation of calving grounds.
Caribou are large-scale migratory animals and have been known to travel up to 50 miles (80 km) a day. The migratory activities of caribou are usually driven by weather conditions and food availability. [16] Changes in caribou migration can be problematic for Alaska Natives, who depend on caribou for food. [16]
It exchanges heat, water and carbon with the atmosphere, helping to control our weather in Europe and marine ecosystems. Climate change is causing the planet to warm.
From shallow waters to the deep sea, the open ocean to rivers and lakes, numerous terrestrial and marine species depend on the surface ecosystem and the organisms found there. [28] The ocean's surface acts like a skin between the atmosphere above and the water below, and harbours an ecosystem unique to this environment.
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 ...
Phenology is the study of how seasonal events in the lives of plants and animals shift according to the weather and climate, such as how fish or migratory birds respond to the temperature of water ...
Some species are endosymbionts of marine animals and other protists, and play an important part in the biology of coral reefs. Others predate other protozoa, and a few forms are parasitic. Many dinoflagellates are mixotrophic and could also be classified as phytoplankton. The toxic dinoflagellate Dinophysis acuta acquire chloroplasts from its prey.
