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.

Common Seal

最も広く分布する鰭脚類であるゴマフアザラシの近縁種・ゼニガタアザラシ（Phoca vitulina）は、北大西洋と北太平洋の温帯・亜北極沿岸に生息する。成体は最大130kgに達し、海での魚・イカ・甲殻類の捕食と海岸や岩場での休息にほぼ同じ時間を費やす。大きく表情豊かな目は低照度での水中視覚に適応している。シャチ・サメ・ホッキョクグマにとって重要な食料源である。
