Habitat & Geographic Range

blue whale

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical dry broadleaf forests, and tropical and subtropical grasslands and savannas, among 11 distinct biome types. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Asia (Taiwan), Europe (4 countries), and South America (Colombia, Ecuador). Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Common Pinmould

Habitat

Native to Europe and South America, inhabiting ecosystems characteristic of the region.

地球上で生きたことが知られている最大の動物であるシロナガスクジラ（Balaenoptera musculus）は、体長33メートル、体重200トンに達することができ、心臓だけで小型自動車ほどの重さがあります。全ての海洋に生息し、極地の餌場と熱帯の繁殖地の間を回遊します。1日最大4トンのオキアミを摂取する濾過摂食者です。20世紀の捕鯨による絶滅危機からの回復後、世界的な個体数は10,000〜25,000頭と推定される絶滅危惧種です。

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.
