In the arctic ecosystem, copepod Calanus glacialis is a keystone species. Without it, the ecosystem may collapse since C. glacialis is where other predators get there fat from. C. glacialis is a crustacean that has evolved to take advantage of two algae blooms on the ice’s edge that have historically been very consistent. Now, the second bloom that would normally happen right after the crustacean’s mating period and feed its young is happening much earlier as a result of global warming. Researchers don’t think there is much hope for this vital source of nutriment in the arctic, and wonder how other organisms will cope with its dropping numbers.
