pigargo-americano

A ave nacional dos Estados Unidos e símbolo do sucesso conservacionista americano, a águia-careca tem uma envergadura de até 2,4 metros e habita florestas e zonas húmidas próximas de águas abertas em toda a América do Norte. Quase extinta na década de 1960 devido ao envenenamento por DDT e à caça, recuperou de forma notável após as proibições de pesticidas e a Lei das Espécies em Perigo.

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.
