Ivory Gull

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

Shenandoah Salamander Shenandoah Salamander
The Shenandoah Salamander lives in an isolated, high altitude region of Shenandoah National Park, USA. Like all amphibians who have thin, permeable skin, salamanders are very sensitive to environmental changes. If average temperatures or moisture increase, this salamander, restricted to its cool micro-climate, will be at risk—having no place to go but to lower, even warmer, altitudes. If warming causes other species of lower altitude salamanders to migrate higher, they will compete for the Shenandoah's cool, moist habitats.
Whooping Crane Whooping Crane
Before 1800 there were an estimated 10–20,000 Whooping Cranes in North America. By 1941, because of hunting and habitat destruction, there were fewer than 20. There are now approximately 350–380 in the wild. The wild Whooping Crane population has only one winter habitat—a wildlife refuge on the Gulf Coast in Texas; and one spring breeding habitat—a prairie wetlands in Alberta. Severe storms, sea level rise, drought, industrial development and oil spills threaten these habitats. Another significant threat to young Whooping Cranes is colliding with power lines in their migration corridor.
Common Clownfish Common Clownfish
Clownfish live in the shallow waters of coral reefs where they have a mutually beneficial relation with a few species of sea anemone. The anenome protects the Clownfish, and the fish's swimming aerates the water around the anenome. Clownfish are unable to move long distances, and rising ocean temperature and acidity is a threat to their coral reef habitats. Increased acidity also seems to impair their ability to navigate to their home anemones.
Emperor Penguin Emperor Penguin
In 50 years, the mean temperature of western Antarctica has risen nearly 3 °C—more than any other region—reducing the extent and thickness of winter ice. The Emperor Penguin is dependent on the ice for breeding, raising chicks and moulting. Less sea ice decreases zooplankton (krill) which feed on algae that grow on the underside of the ice. Krill are an important part of the food web for the Emperor and other Antarctic marine species.
