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.
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.
Coral reefs flourish in ocean waters that provide few nutrients. They are most commonly found at shallow depths in tropical waters, but deep water and cold water coral reefs exist on smaller scales in other areas. Shallow tropical coral reefs have declined by 50% since 1950, partly because they are sensitive to water conditions. [9]
In 2019 the worst oil spill in Brazilian history polluted more than 2,400 km (1,500 mi) of Brazilian coastline, including parts of Abrolhos Marine National Park and areas of Bahia mangroves and coral reefs. Such areas are considered "particularly vulnerable to damage" and extremely difficult to clean.
Coral reefs are one of the most well-known marine ecosystems in the world, with the largest being the Great Barrier Reef. These reefs are composed of large coral colonies of a variety of species living together. The corals from multiple symbiotic relationships with the organisms around them. [21] Coral reefs are being heavily affected by global ...
Mangroves are one of the most productive and ecologically important ecosystems on earth. The rates of primary production of mangroves equal those of tropical humid evergreen forests and coral reefs. [114] As a globally relevant component of the carbon cycle, mangroves sequester approximately 24 million metric tons of carbon each year.
SMEs are characterized by carbonate reefs, which support many species. Estimates suggest that coral reefs alone may host between 1-9 million species. The three main types of reef formations are: [8] Fringing Reefs: attached to the shore; Barrier Reefs: separated from the mainland by a lagoon; Atoll Reefs: ring-shaped reefs surrounding a lagoon
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. [ 1 ] The ocean's surface acts like a skin between the atmosphere above and the water below, and hosts an ecosystem unique to this environment.
