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 carpetgrass

<em>Axonopus fissifolius</em>, commonly known as common carpetgrass, is a grass species with a broad global distribution spanning Africa, Asia, Europe, the Americas, and Oceania. It typically thrives in grasslands, wetlands, forests, and cultivated areas, often tolerating poorly drained and low-fertility soils. Common carpetgrass belongs to the genus <em>Axonopus</em> within the family Poaceae. It is a low-growing, stoloniferous grass that typically forms dense mats along roadsides, disturbed areas, lawns, and pastures in warm and humid climates. The species is frequently used as a lawn and pasture grass in tropical and subtropical regions due to its tolerance of mowing and its ability to spread vegetatively. Biological traits such as average lifespan, plant height, and biomass of this species remain poorly documented in the scientific literature. The species has not yet been formally evaluated by the IUCN, and its global conservation status therefore remains undetermined. Its widespread occurrence across multiple continents and highly varied habitats suggests strong ecological adaptability.
