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).

Compressed Flapwort

Habitat

Native to Europe, inhabiting ecosystems characteristic of the region.

Range

Distributed across Belgium, Norway, and Sweden.

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.

Compressed Flapwort

<em>Nardia compressa</em>, commonly called the Compressed Flapwort, is a leafy liverwort in the family Jungermanniaceae, a lineage of non-vascular land plants (division Marchantiophyta) that diverged from other embryophytes over 400 million years ago. This small, mat-forming bryophyte typically colonizes moist, acidic substrates along stream banks, seepages, and wet rock faces in cool-temperate habitats throughout Europe. Its flattened, overlapping leaves give the plant a compressed appearance, which inspired both its common and scientific names. Like all liverworts, <em>Nardia compressa</em> lacks true vascular tissue and absorbs water and nutrients directly through its leaf surfaces, deriving energy through photosynthesis rather than heterotrophic feeding. The species has been recorded in Belgium, Norway, and Sweden, suggesting an affinity for the moist, boreal and Atlantic climatic zones of northwestern and northern Europe. It is currently assessed as Least Concern by the IUCN, indicating no immediate extinction risk across its known range. Biological traits including individual lifespan, reproductive rates, and specific growth measurements remain poorly documented relative to vascular plant species, though liverworts are generally slow-growing perennial organisms tightly dependent on stable moisture regimes.
