Common Pinmould

<em>Mucor mucedo</em>, the common pin mould, is a zygomycete fungus in the family Mucoraceae, belonging to one of the earliest-diverging lineages of terrestrial fungi. It is characterised by long, unbranched sporangiophores topped with spherical, pin-like sporangia that release large numbers of asexual spores, giving infested substrates a grey or white mouldy appearance. The species is a saprotrophic decomposer, typically colonising dung, soil, decaying organic matter, and stored food products, where it plays a role in nutrient cycling and organic matter breakdown. <em>Mucor mucedo</em> is distributed across Europe, with records from Belgium, Denmark, and Norway, and in South America including Brazil, and is likely cosmopolitan given the ease with which its spores disperse through the air. It is assessed as Not Evaluated on the IUCN Red List, as fungal conservation assessments remain incomplete globally. Sexual reproduction involves the fusion of compatible mating types to produce resistant zygospores. Biological traits such as colony growth rates under standardised conditions, typical biomass production, and detailed ecological roles beyond general decomposition remain poorly documented in the scientific literature. The species is non-pathogenic to healthy humans but may cause opportunistic infections in immunocompromised individuals.

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。
