Seagrass meadows also provide physical habitat in areas that would otherwise be bare of any vegetation. Due to this three dimensional structure in the water column, many species occupy seagrass habitats for shelter and foraging. It is estimated that 17 species of coral reef fish spend their entire juvenile life stage solely on seagrass flats. [87]
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.
The diagram on the right shows the principal interactions between mangroves, seagrass, and coral reefs. [136] Coral reefs, seagrasses, and mangroves buffer habitats further inland from storms and wave damage as well as participate in a tri-system exchange of mobile fish and invertebrates. Mangroves and seagrasses are critical in regulating ...
Other near-shore (neritic) zones can include mudflats, seagrass meadows, mangroves, rocky intertidal systems, salt marshes, coral reefs, lagoons. In the deep water, hydrothermal vents may occur where chemosynthetic sulfur bacteria form the base of the food web.
This in turn links them to coral reefs, mangroves, salt marshes, and even oyster reefs (Bjork, Mats, et al.). Seagrasses are distributed through six main global bioregions; Temperate North Atlantic, Tropical Atlantic, Mediterranean, Temperate North Pacific, Tropical Indo-Pacific and Temperate Southern Oceans.
In 1998, coral reefs experienced the most severe mass bleaching events on record, when vast expanses of reefs across the world died because sea surface temperatures rose well above normal. [ 57 ] [ 58 ] Some reefs are recovering, but scientists say that between 50% and 70% of the world's coral reefs are now endangered and predict that global ...
It includes the Florida Reef, the only barrier coral reef in North America [1] and the third-largest coral barrier reef in the world. It also has extensive mangrove forest and seagrass fields. The Florida Keys National Marine Sanctuary, designated on December 28, 1990, [2] was the ninth national marine sanctuary to be established.
