Chrysoprase Mallee

The Chrysoprase Mallee (Eucalyptus repullulans) is a small, multi-stemmed mallee eucalyptus endemic to the southwestern corner of Western Australia. It grows in the mallee form characteristic of many Eucalyptus species in nutrient-poor, drought-prone environments: multiple lignotuberous stems arise from a swollen root crown (lignotuber), allowing rapid resprouting following wildfire or mechanical damage. E. repullulans typically inhabits sandy soils on heathlands and sandplains, often in association with kwongan vegetation dominated by Proteaceae and Myrtaceae. The species is assessed as Least Concern by the IUCN, suggesting stable populations not currently under acute threat. Like many Western Australian mallees, it produces small to medium-sized white or cream flowers that provide nectar and pollen resources for native bees, honeyeaters, and other pollinators. The lignotuber enables long-term survival and regeneration in fire-prone landscapes typical of the Australian Mediterranean climate zone. Mallee eucalypts are ecologically important as structural vegetation components in landscapes where taller trees cannot establish. Conservation of Eucalyptus repullulans is supported through the broader protection of Southwest Australian Floristic Region habitats, one of the world's biodiversity hotspots.

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.
