Colchicum Rust

Uromyces colchici, commonly referred to as Colchicum Rust, is a fungal pathogen in the order Pucciniales, family Pucciniaceae. This rust fungus is associated with plants in the genus Colchicum, commonly known as autumn crocuses or meadow saffrons. The species has been recorded in the United Kingdom and is presumed to occupy European ecosystems more broadly. Rust fungi in the genus Uromyces are obligate biotrophs, meaning they complete their life cycles on living host plant tissue. They typically cause visible lesions or pustules on leaves and stems of their host plants, which can affect host vigor. Uromyces colchici has not been formally assessed under the IUCN Red List, and its conservation status is unknown. Biological traits such as reproductive specifics and dispersal mechanisms follow those typical of rust fungi but have not been specifically documented for this species in available records. Biological traits of this species remain poorly documented in the scientific literature. Its ecological impact on Colchicum populations in European grassland and woodland habitats is not well quantified.

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.
