Poison dart frogs are characterized by bright colors which serve to warn predators of their toxicity. The frog poison is made up of toxic alkaloids sequestered from their arthropod (mostly mites and ants) prey. The skin secretion of some species is so potent that it is used on the tip of hunting arrows and darts by South American tribes.
There are more than 160 known species of poison dart frogs.

Arctic upheaval: new book outlines challenges at the top of the world
(02/16/2015) For most of us, the Arctic is not at the front of our minds. We view it as cold, stark, and, most importantly, distant. Yet, even in an age of vast ecological upheaval, one could argue that no biome in the world is changing so rapidly or so irrevocably. Two hundred plus years of burning fossil fuels has warmed up the top of our planet more quickly than anywhere else.
U.S. Central Plains and Southwest will likely face apocalyptic drought
