ハクトウワシ

アメリカの国鳥であり保全の成功を象徴するハクトウワシは翼開長が最大2.4 mに達し、北米全域の水辺近くの森林や湿地に生息する。強力な空中捕食者兼腐肉食者で魚を主食とするが、水鳥や腐肉も捕食する。DDT汚染と狩猟によって1960年代にほぼ絶滅に瀕したが、農薬の使用禁止と絶滅危惧種法の施行により劇的に回復した。

<em>Collaria arcyrionema</em> is a myxomycete — a plasmodial slime mould — belonging to the class Myxomycetes within the phylum Mycetozoa. Slime moulds of the genus Collaria are not true fungi but are instead classified within the group Amoebozoa, reflecting their distinctive biology that combines amoeba-like feeding behaviour with a complex, multi-stage life cycle. <em>Collaria arcyrionema</em> produces small, stalked sporangia — spore-bearing structures — that are characteristic of the genus, typically forming on decaying organic matter such as dead wood, leaf litter, and damp substrate in forested environments. The species has a reported distribution in Brazil, Norway, and Sweden, with occurrence noted across parts of Europe and South America. Like other myxomycetes, <em>Collaria arcyrionema</em> plays a role in nutrient cycling by consuming bacteria and organic detritus during its plasmodial phase. Detailed biological traits including typical lifespan measures and physical dimensions are poorly documented for this species in available literature.
