El Nispero, Panama: A Panamanian golden frog (Atelopus zeteki) at the El Nispero zoo. Considered a national icon and good luck charm, the Panamanian golden frog is now likely extinct in the wild because of chytrid fungus, a deadly disease that scientists say may be exacerbated by climate change. Currently unstoppable and untreatable in the wild, the fungus affects the skin of amphibians through which many drink and breathe. It can kill 80% of native amphibians within months Photograph: Alberto Lowe/Reuters

Kraitsy, Belarus: Black grouse court at a mating ground in the Berezinsky reserve. Each spring these rare birds perform a dramatic dance of love – called a lek – in the hope of securing a mate for the breeding season. But changing climate patterns are threatening the rare bird, with numbers believed to have fallen by 40% in two years in the UK's Pennines. Consecutive cold, wet summers, the worst conditions in almost two decades, have set back recovery, with the number of males dropping from 1,200 to 850 Photograph: Vasily Fedosenko/Reuters
