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。

Common sawfly

<em>Allantus basalis</em> is a sawfly species within the family Tenthredinidae, order Hymenoptera, native to temperate regions of North America and Scandinavia, including records from Canada, Norway, Sweden, and the United States. As a member of the subfamily Allantinae, this species is part of a broadly distributed group of plant-associated insects. Adults are typically small, dark-bodied insects resembling stout wasps, and larvae are known to feed on the foliage of their specific host plants, though the precise host associations for this species remain incompletely characterized in the literature. <em>Allantus basalis</em> inhabits woodland margins, shrubby areas, and vegetated habitats across its range where suitable host plants occur. The species has not been assessed by the IUCN, and its conservation status is therefore listed as Not Evaluated. Biological traits for this species remain poorly documented in the scientific literature, including data on average lifespan, body size, weight, and specific dietary composition. Population trends are currently unknown, and the species does not appear to face significant recognized threats at this time.
