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。

common European cockle

<em>Cerastoderma edule</em>, the common European cockle, is an intertidal bivalve mollusc in the family Cardiidae, classified as Least Concern by the IUCN Red List. The species is native to European coastal waters and has been documented in Belgium, Denmark, Iceland, Norway, and Sweden, where it typically inhabits sandy and muddy intertidal and shallow subtidal sediments in estuaries, bays, and open coastlines. <em>Cerastoderma edule</em> is a filter feeder, drawing in seawater through its siphons to extract phytoplankton, bacteria, and organic particles. It is recognized by its distinctive ribbed, cream-colored shell with radiating ridges and concentric growth lines. Cockles are a keystone species in many European coastal ecosystems, providing an important food source for shorebirds such as oystercatchers and knots, predatory fish, crabs, and starfish. The species also supports one of the most commercially significant shellfish fisheries in Europe, with large-scale harvesting operations in the UK, the Netherlands, and Ireland. Dense cockle beds stabilize intertidal sediments and contribute to benthic productivity. Population dynamics are closely linked to sea surface temperature, salinity, and sediment availability, making this species a useful indicator of estuarine ecosystem health. Biological traits of this species remain poorly documented in the scientific literature.
