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.

koala

オーストラリア東部・南東部を代表する有袋類で、体重は最大15kgに達し、低カロリーのユーカリの葉食から得るエネルギーを節約するために1日最大22時間を睡眠に費やす。他の哺乳類の多くを死に至らしめる有毒なユーカリ成分を処理するために高度に特化しており、解毒に特別に適応した腸内微生物叢を持つ。クラミジア感染症、生息地の伐採、気候変動により個体数が激減し、2022年に絶滅危惧種に指定された。
