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.

Compact Swan-neck Moss

<em>Campylopus brevipilus</em>, compact swan neck moss, is a small acrocarpous moss in the family Dicranaceae found in western Europe, with confirmed occurrences in Belgium, Denmark, Norway, Portugal, and Sweden. Like other members of the genus Campylopus, it is characterised by distinctive narrow leaves with a strong costa that typically extends into a hair point, giving the shoots a bristly appearance when dry. This species inhabits wet heathlands, blanket bog margins, and moist acidic sandy or peaty substrates, often growing in open gaps among heather and other dwarf shrubs. It is particularly associated with the Atlantic heathland zone of western Europe, a globally threatened habitat type that has declined dramatically over the past century due to agricultural intensification, afforestation, and the suppression of traditional heathland management practices such as burning and grazing. The IUCN classifies compact swan neck moss as Vulnerable, reflecting its restricted habitat associations and ongoing heathland loss across its European range. The species forms distinctive dense cushions or mats contributing to bryophyte diversity in oligotrophic heathland communities. Biological traits including growth rates, spore dispersal ecology, and precise morphological dimensions remain poorly documented in formal scientific literature. Conservation of this species depends on the active management and restoration of Atlantic heathland across its range in northwestern Europe and the Iberian Peninsula.
