The Caribbean's coral reefs will cease to exist in 20 years if a conservation effort is not made. [127] In 2005, 34 percent of Jamaica's coral reefs were bleached due to rising sea temperatures. [128] Jamaica's coral reefs are also threatened by overfishing, pollution, natural disasters, and reef mining. [129]
Coral reefs are among the more productive and diverse ecosystems on the planet, but one-fifth of them have been lost in recent years due to anthropogenic disturbances. [14] [15] Coral reefs are microbially driven ecosystems that rely on marine microorganisms to retain and recycle nutrients in order to thrive in oligotrophic waters.
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. Coral belongs to the class Anthozoa in the animal phylum Cnidaria, which includes sea anemones and ...
Experts say dying corals are animals, vegetables and minerals, so the fight to save them is anything but simple.
Coral reefs are breathtaking homes for a diverse range of marine life, including turtles, sharks and eels. They're under threat from pollution, fishing and climate change though, and the data ...
The resilience of coral reefs is the biological ability of coral reefs to recover from natural and anthropogenic disturbances such as storms and bleaching episodes. [1] Resilience refers to the ability of biological or social systems to overcome pressures and stresses by maintaining key functions through resisting or adapting to change. [ 2 ]
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 ...
Planktivorous fish (8, some damselfishes and triggerfishes) transfer energy from zooplankton up to reef predators like jacks (9), [101] which provide top-down control of reefs [102] and are important targets for shoreline recreational fisherfolk. [103] Grazers (10, chubs) help keep coral reefs from being overgrown by macroalgae. [104]
