Habitat & Geographic Range

American Bald Eagle

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical dry broadleaf forests, and flooded grasslands and savannas, among 10 distinct biome types spanning the Neotropic and Palearctic realms. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Europe (8 countries), North America (United States), and South America (Ecuador).

Comb Notchwort

Habitat

Native to Europe and North America and South America, inhabiting ecosystems characteristic of the region.

Range

Distributed across Colombia, Norway, Sweden, and United States.

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.

Comb Notchwort

<em>Sphenolobus minutus</em>, the comb notchwort, is a small leafy liverwort in the family Anastrophyllaceae, assessed as Least Concern on the IUCN Red List. It has a broad distribution across Europe and both North and South America, indicating a widespread presence in the Northern and Southern Hemispheres. As a liverwort, <em>S. minutus</em> belongs to the division Marchantiophyta and is among the earliest-diverging land plant lineages. It inhabits moist, shaded environments on decaying wood, mineral soil, and rock surfaces in forested and montane settings. The plant forms dense mats or patches of small, deeply lobed leaves arranged on a creeping stem, with lobes that may appear notched or comb-like in texture. Liverworts reproduce both sexually via spores and vegetatively via gemmae. <em>S. minutus</em> is sensitive to habitat moisture and atmospheric conditions, making it a potential bioindicator of environmental quality.
