Regions where oceanic or subtropical highland climates (Cfb, Cfc, Cwb, Cwc) are found. An oceanic climate, also known as a marine climate or maritime climate, is the temperate climate sub-type in Köppen classification represented as Cfb, typical of west coasts in higher middle latitudes of continents, generally featuring cool to warm summers and cool to mild winters (for their latitude), with ...
Marine ecosystems are the largest of Earth 's aquatic ecosystems and exist in waters that have a high salt content. These systems contrast with freshwater ecosystems, which have a lower salt content. Marine waters cover more than 70% of the surface of the Earth and account for more than 97% of Earth's water supply [1][2] and 90% of habitable ...
Climate change is already now altering biomes, adversely affecting terrestrial and marine ecosystems. [2][3] Climate change represents long-term changes in temperature and average weather patterns. [4][5] This leads to a substantial increase in both the frequency and the intensity of extreme weather events. [6]
v. t. e. A seagrass meadow or seagrass bed is an underwater ecosystem formed by seagrasses. Seagrasses are marine (saltwater) plants found in shallow coastal waters and in the brackish waters of estuaries. Seagrasses are flowering plants with stems and long green, grass-like leaves. They produce seeds and pollen and have roots and rhizomes ...
Phytoplankton (/ ˌfaɪtoʊˈplæŋktən /) are the autotrophic (self-feeding) components of the plankton community and a key part of ocean and freshwater ecosystems. The name comes from the Greek words φυτόν (phyton), meaning ' plant ', and πλαγκτός (planktos), meaning 'wanderer' or 'drifter'. [1][2][3] Phytoplankton obtain their ...
Marine coastal ecosystem. A marine coastal ecosystem is a marine ecosystem which occurs where the land meets the ocean. Marine coastal ecosystems include many very different types of marine habitats, each with their own characteristics and species composition. They are characterized by high levels of biodiversity and productivity.
Human activities affect marine life and marine habitats through overfishing, habitat loss, the introduction of invasive species, ocean pollution, ocean acidification and ocean warming. These impact marine ecosystems and food webs and may result in consequences as yet unrecognised for the biodiversity and continuation of marine life forms. [3]
Intertidal ecology is the study of intertidal ecosystems, where organisms live between the low and high tide lines. At low tide, the intertidal is exposed whereas at high tide, the intertidal is underwater. Intertidal ecologists therefore study the interactions between intertidal organisms and their environment, as well as between different ...
