Staghorn Coral
Latin name: Acropora Cervicornis,Conservsation status: critically endangered (population is stable)
Coral reefs are the most diverse ecosystems in the marine world and can take 10,000 years to form. They cover less than 1% of the ocean floor but are habitat for at least 25% of all known marine life. A coral is made up of thousands of tiny animals called polyps, protected by a hard skeleton. There are 160 different species of Staghorn Coral.
In the last 30 years the Staghorn Coral population has decreased by 80% from disease, pollution, development and damage. Climate change is increasing the risk of extinction. Corals live in symbiotic (mutually beneficial) relation with algae. The coral receives nutrients and oxygen from algae, and the algae receive nutrients and carbon dioxide from the coral. Rising sea temperature increases algae growth so oxygen levels become too high for the coral, causing "bleaching"—the coral expels the algae and dies. Higher ocean acidity contributes to bleaching and also reduces the ability of corals and other marine animals to build hard shells. Other threats from climate change are sea level rise, changes in currents and storm damage.
Other animals effected by climate change
Polar BearPolar Bears live only in the Arctic. Loss of sea ice has a critically adverse effect on Polar Bears. They hunt from the edge and build snow dens on the ice for resting and raising their cubs. Sea ice decline could open the Arctic to shipping and tourism, further disturbing Arctic habitats. Other threats are oil development and industrial pollution that reaches the Arctic through air and ocean currents.
Leatherback Sea TurtleClimate change impacts the Leatherback in two main ways: an increase in the temperature of nesting sands causes a greater proportion of females to hatch, destabilizing future populations; and sea level rise and stronger, more frequent storms erode nesting beaches and wash away eggs and hatchlings. The Leatherback is also threatened from fisheries by-catch, egg collection, coastal development, pollution and ingestion of floating plastics.
Rusty Patched Bumble BeeThe Rusty Patched is the first bee to be listed as endangered in the US. Populations have declined as much as 87% from habitat loss, disease and pesticides. Climate threats include: warming and precipitation, early snow, late frost and drought. Bees and butterflies are important agricultural pollinators. In 2016, 40% of invertebrate pollinators (bees and butterflies) were listed as threatened with extinction.
Arctic FoxThe Arctic tundra is a region of shrubs, grasses and permanently frozen subsoil. Warming could change the tundra to boreal forest—habitat for the Red Fox. The Red Fox, a predator and a competitor for food, is already beginning to migrate north into the Arctic Fox's territory. Milder tundra weather also causes changes in the population of lemmings and rodents—main food for the Arctic Fox.
