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).

coastal hook moss

Habitat

Native to Europe, inhabiting ecosystems characteristic of the region.

Range

Distributed across 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.

coastal hook moss

Sanionia orthothecioides, the coastal hook moss, is a pleurocarpous moss in the family Scorpidiaceae distributed across Arctic and subarctic coastal regions of Norway, Sweden, and adjacent high-latitude environments. Mosses in the genus Sanionia are characteristic components of moist Arctic tundra, snowbed communities, and coastal habitats where they form extensive carpets in areas of persistent soil moisture near snowmelt or coastal spray. Sanionia orthothecioides grows in dense cushions or mats on wet rocks, coastal cliff ledges, soil banks, and peatlands in the low Arctic and subarctic zones, tolerating periodic inundation, salt spray exposure, and freeze-thaw cycles that characterize coastal high-latitude environments. Like other mosses, it lacks true vascular tissue and absorbs water and nutrients directly through leaf surfaces, making it sensitive to desiccation but resilient to temporary submersion. Arctic and subarctic mosses are ecologically critical components of tundra carbon cycling, accumulating organic matter in cold, wet conditions and contributing substantially to the global peat carbon pool. Sanionia orthothecioides is classified as Least Concern by the IUCN, being widely distributed across coastal Arctic regions and not currently threatened by any major population-level pressures.
