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.

Common Bird'S Nest

The common bird's nest (<em>Crucibulum laeve</em>) is a small cup-shaped fungus belonging to the family Nidulariaceae, known for its distinctive nest-like fruiting bodies that contain egg-like spore packages called peridioles. It is classified as Least Concern on the IUCN Red List. The species has been documented in Taiwan, Norway, Portugal, Sweden, the United States, and Brazil, reflecting a wide global distribution. <em>Crucibulum laeve</em> typically grows on decaying wood, forest floors, and decomposing organic material, where it plays a role in breaking down cellulose-rich substrates. The funnel-shaped cups, often pale tan in color, are designed to use splashing raindrops as a dispersal mechanism, propelling the peridioles outward to deposit spores on new substrates. This splash-cup dispersal strategy is a distinctive adaptation shared among bird's nest fungi. Biological traits of this species remain poorly documented in the scientific literature.
