Clavaria krieglsteineri is a rare club fungus in the family Clavariaceae, described from central European specimens and named in honor of mycologist G.J. Krieglsteiner. Like other members of the genus Clavaria, it produces simple, slender, unbranched to sparingly forked fruiting bodies, typically pale in coloration, emerging from soil in grassland or lightly wooded habitats. The morphology of Clavaria species can be difficult to distinguish without microscopic examination of spore size, shape, and basidia characters, and molecular phylogenetics has significantly reorganized the genus in recent decades. Clavaria krieglsteineri inhabits unimproved grasslands and semi-natural meadows in central Europe, ecosystems that have declined steeply under agricultural pressure. These grassland coral fungi are sensitive indicators of long-undisturbed soils and are frequently used in national biodiversity assessments as markers of ecologically valuable meadowland. The species is saprotrophic, recycling nutrients from decaying organic matter in shallow soils. Fruiting typically occurs in late summer through autumn, contingent on adequate soil moisture. As with many specialist grassland fungi, Clavaria krieglsteineri faces threats from fertilizer application, ploughing, and the conversion of ancient meadows to arable land or improved pasture. The species is listed on regional red lists in parts of central Europe and is considered rare in the localities where it has been documented.

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.
