白头海雕

白头海雕是美国国鸟，也是美国生态保护史上的成功案例，曾因滴滴涕（DDT）的广泛使用而濒临灭绝，经保护措施的实施后种群数量已显著恢复。该物种在IUCN红色名录中被评估为无危（LC），以白色头颈和尾羽与深棕色体羽形成的鲜明对比为主要识别特征。它们主要以鱼类为食，也会捕食哺乳动物和腐肉。

<em>Comatricha alta</em> is a myxomycete, or plasmodial slime mold, belonging to the order Stemonitidales within the class Myxomycetes. Like all members of the genus <em>Comatricha</em>, it occupies a unique position in the tree of life, exhibiting characteristics that were historically associated with both fungi and protozoa but are now classified within the supergroup Amoebozoa. The species produces fruiting bodies consisting of delicate, thread-like capillitial networks enclosed within a peridium, and forms spores that are dispersed by air currents. <em>C. alta</em> has been documented from Europe, where it occurs on decaying woody substrates such as rotting logs, fallen bark, and dead plant matter in forested and shaded environments. It thrives in moist, humid conditions that support the feeding plasmodial stage, during which it engulfs bacteria, fungal spores, and organic particles. No quantitative biological traits data are available for this species.
