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.

Chroomonas virescens is a species of cryptophyte alga in the family Chroomonadaceae, characterized by a greenish coloration, as reflected in the specific epithet virescens, meaning becoming green. This greenish hue distinguishes it from many Chroomonas species that display blue-green to brown tones, suggesting a particular phycobiliprotein composition or a balance of chlorophyll to accessory pigments that shifts the overall color toward green. Cryptophyte algae display a wide range of colors depending on the dominant phycobiliprotein in their plastid: phycoerythrin-rich species appear red to orange-brown, while phycocyanin-rich species tend toward blue-green or olive tones. Chroomonas virescens has been documented from European freshwater habitats. Like other Chroomonas species, it is a small, biflagellate, planktonic or periphytic unicell that contributes to primary production in its aquatic ecosystem. Freshwater cryptophytes perform an important ecological function as cold-tolerant primary producers that can be active during periods when many other algae are dormant. The species has not been assessed under IUCN conservation criteria.
