Extent of Temperate coniferous forest. Temperate coniferous forest is a terrestrial biome defined by the World Wide Fund for Nature.Temperate coniferous forests are found predominantly in areas with warm summers and cool winters, and vary in their kinds of plant life.
A coral reef is an underwater ecosystem characterized by reef-building corals. Reefs are formed of colonies of coral polyps held together by calcium carbonate . [ 1 ] Most coral reefs are built from stony corals , whose polyps cluster in groups.
It is estimated that 17 species of coral reef fish spend their entire juvenile life stage solely on seagrass flats. [87] These habitats also act as a nursery grounds for commercially and recreationally valued fishery species, including the gag grouper ( Mycteroperca microlepis ), red drum, common snook , and many others.
Sargassum is a genus of brown macroalgae in the order Fucales of the Phaeophyceae class. [1] Numerous species are distributed throughout the temperate and tropical oceans of the world, where they generally inhabit shallow water and coral reefs, and the genus is widely known for its planktonic (free-floating) species.
Marine botany is the study of flowering vascular plant species and marine algae that live in shallow seawater of the open ocean and the littoral zone, along shorelines of the intertidal zone, coastal wetlands, and low-salinity brackish water of estuaries. It is a branch of marine biology and botany.
A marine coastal ecosystem is a marine ecosystem which occurs where the land meets the ocean. Worldwide there is about 620,000 kilometres (390,000 mi) of coastline. Coastal habitats extend to the margins of the continental shelves, occupying about 7 percent of the ocean surface area.
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.
A number of studies from around the world have found that there is a wide range in the concentrations of C, N, and P in seagrasses depending on their species and environmental factors. For instance, plants collected from high-nutrient environments had lower C:N and C:P ratios than plants collected from low-nutrient environments.
