Chucanti Salamander

The Chucantí Salamander (Bolitoglossa chucantiensis) is a Critically Endangered plethodontid salamander known from the Chucantí mountain massif in the Darien region of eastern Panama. The genus Bolitoglossa represents the largest genus of salamanders globally, with the greatest diversity in Central and South America. B. chucantiensis was described from a small area of cloud forest at mid-to-high elevations in the Serranía de Majé range, an isolated and poorly surveyed mountain system in the Darién Province. Its Critically Endangered status reflects an extremely restricted range (estimated area of occupancy potentially under 10 km²), ongoing deforestation threatening its cloud forest habitat from agricultural expansion and cattle ranching, and the threat of chytridiomycosis, the amphibian fungal disease that has devastated salamander and frog populations across the Americas. Like other Bolitoglossa species, it is a direct-developing salamander that bypasses a free-swimming larval stage, laying eggs in moist terrestrial habitats. Conservation of the Chucantí Nature Reserve, established partly to protect the biodiversity of this mountain, is critical for the survival of this species.

Polar bear

지구상에서 가장 큰 육상 육식동물인 북극곰은 700kg을 넘을 수 있으며 캐나다에서 러시아까지 북극 해빙 전역에 분포한다. 고리 물범과 수염 물범을 사냥하기 위해 해빙에 의존하는 고도로 특수화된 해양 포유류이다. 광활한 거리를 헤엄쳐 다닐 수 있는 뛰어난 수영 실력을 가지고 있다. 취약종으로 등재되어 있으며, 기후 변화로 인한 급격한 북극 해빙 감소로 심각한 압력을 받고 있다.
