Fish biomass and average trophic level of fisheries landing are decreasing, leading to declines in marine biodiversity. In particular, local extinctions have led to declines in large, long-lived, slow-growing species, and those that have narrow geographic ranges. [48] Biodiversity declines can lead to associated declines in ecosystem services.
It was developed as the information management component of the ten year Census of Marine Life (CoML) (2001-2010), but is not limited to CoML-derived data, and aims to provide an integrated view of all marine biodiversity data that may be made available to it on an open access basis by respective data custodians. According to its web site as at ...
The biodiversity and natural productivity of the coral triangle are under threat from poor marine management (primarily from coastal development, overfishing and destructive fishing), lack of political will, poverty, high market demand, local disregard for rare and threatened species, climate change (warming, ocean acidification and rising sea ...
AquaMap for Mola mola, the ocean sunfish. AquaMaps is a collaborative project with the aim of producing computer-generated (and ultimately, expert reviewed) predicted global distribution maps for marine species on a 0.5 × 0.5 degree grid of the oceans based on data available through online species databases such as FishBase and SeaLifeBase and species occurrence records from OBIS or GBIF and ...
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 ...
Megadiversity means exhibiting great biodiversity. The main criterion for megadiverse countries is endemism at the level of species, genera and families. A megadiverse country must have at least 5,000 species of endemic plants and must border marine ecosystems.
The National Biodiversity Assessment (NBA) is recurring project by the South African National Biodiversity Institute in collaboration with the Department of Environmental Affairs and several other organisations to assess the state of South Africa's biodiversity over time as an input for policy and decision making where the environment may be affected.
A marine protected area (MPA) is a protected area that includes primarily marine environment and biodiversity. The International Union for Conservation of Nature (IUCN) defines a protected area as:
