Ivory Gull
Latin name: Pagophila Eburnea,Conservsation status: endangered (population is decreasing)
Ivory Gulls build large nests of dry grass, moss, lichen and seaweed. In winter and early spring when food is scarce, foraging Caribou eat the nests. The gulls live in the high Arctic, rarely migrating any farther south than the Bering Sea.
Ivory Gulls are almost entirely dependent on sea ice and glaciers for nesting and food foraging. They feed on fish and shellfish that thrive near the edge of the ice, and on the remains of seals left by Polar Bears. Seal blubber is a source of heavy contaminants—Ivory Gull eggs show a higher concentration of mercury and pesticides than any Arctic sea bird. Other threats are illegal hunting and disturbance from diamond mining in the Canadian Arctic.
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.
BelugaBelugas live in Arctic and Sub-Arctic waters. Impacts from climate change include: an increase in ship traffic as sea ice declines, oil exploration and extraction, fisheries by-catch, and disruption of the food web. As Arctic waters warm and currents change, the Humpback (a competitor) and the Orca (a predator) may move north and stay longer. Some Beluga populations are also threatened by hunting, pollution and habitat loss.
Sockeye SalmonFor decades wild salmon populations have been in decline from human causes: over fishing; habitat degradation—logging, mining, agriculture and dams; pollution; and interaction with hatchery or farmed salmon. These conditions and threats may hinder their ability to adapt to the effects of climate change. Salmon thrive at specific freshwater temperatures—warming air raises water temperature. Early snow melt and increased rains cause physical changes to spawning streams.
Staghorn CoralIn 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.
