Western Glacier Stonefly

Western Glacier Stonefly

Latin name: Zapada Glacier,
Conservsation status: vulnerable (population is decreasing)

One of 3,500 species of Stoneflies, this rare insect breeds in only a few cold water streams immediately below melting glaciers or next to permanent snowfields in Glacier National Park, USA.

Since 1960, the average summer temperature in Glacier National Park has increased by around 1 °C and glaciers have declined by 35%. By counting Stoneflies, scientists can determine how quickly glaciers are melting and the temperature of streams. In a two year search begun in 2011, scientists found the Stonefly in only one of the six streams it had previously occupied and discovered that it had retreated to two different streams at higher altitudes. Satellite data confirm that the world’s glaciers are declining, affecting the availability of fresh water for humans, animals and plants, and contributing to sea level rise.


Other animals at risk

Ringed Seal
Ringed Seal
All populations of Ringed Seals are expected to be adversely affected by climate change because of dependence on sea ice and snow dens for breeding, protecting pups, moulting and resting. Early warming causes pups to separate prematurely from their mothers. As sea ice declines, other threats are fisheries by-catch, increased shipping, tourism and development. Seals are vulnerable to disease from heavy concentrations of pollutants that have accumulated in the Arctic food web.
Beluga
Beluga
Belugas 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.
Rusty Patched Bumble Bee
Rusty Patched Bumble Bee
The 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.
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.
