American Bald Eagle

The national bird of the United States and a symbol of American conservation success, bald eagles have a wingspan of up to 2.4 meters and inhabit forests and wetlands near open water across North America. Powerful aerial predators and scavengers, they specialize in fish but also take waterfowl and carrion. Nearly extinct by the 1960s due to DDT poisoning and hunting, the bald eagle recovered dramatically following pesticide bans and the Endangered Species Act.

Tolypothrix rivularis is a filamentous, heterocyst-bearing cyanobacterium found in freshwater streams, rivers, and pools, often attached to rocks and aquatic plants in flowing water habitats. It can fix atmospheric nitrogen through heterocysts and forms false-branching filaments characteristic of the genus. This species contributes to nutrient cycling in lotic freshwater ecosystems across temperate zones.
