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。

compact peat moss

<em>Sphagnum compactum</em>, compact peat moss, is a bryophyte in the family Sphagnaceae with a wide distribution across bog and fen habitats in Europe, North America, and parts of South America. As a member of the ecologically pivotal genus Sphagnum, it plays a fundamental role in peatland ecosystems, contributing to peat formation, water retention, and carbon sequestration. Compact peat moss typically grows in dense low mats or hummocks on acidic, nutrient-poor wetlands including raised bogs, blanket bogs, and wet heathlands. It is characteristically adapted to waterlogged, acidic conditions and is a characteristic component of bog moss communities alongside other Sphagnum species. The genus Sphagnum possesses unique hyaline cells capable of holding up to 20 times their dry weight in water, making these mosses critical for maintaining high water tables in peatland ecosystems. <em>Sphagnum compactum</em> is considered Not Evaluated on the IUCN Red List, though peatland habitats globally face threats from drainage, extraction, agricultural conversion, and climate change-driven drying. Loss of Sphagnum-dominated peatlands has significant consequences for global carbon storage. Biological traits including lifespan, growth rates, and detailed reproductive biology of compact peat moss remain variable and partly documented; the species reproduces both vegetatively and via spores. Conservation of peatlands is essential for preserving both this species and the ecosystems it helps sustain.
