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 Orange Lichen

<em>Xanthoria parietina</em> is a foliose lichen in the family Teloschistaceae, one of the most conspicuous and widely recognized lichens across Europe and North America. It is recorded in Denmark, Norway, Portugal, Sweden, and the United States. The species typically colonizes bark, rock surfaces, walls, roof tiles, and other exposed substrates in nutrient-enriched environments. Its vivid orange to yellow-orange thallus is produced by the pigment parietin, which functions as a photoprotective compound shielding the lichen from UV radiation. <em>Xanthoria parietina</em> is considered a nitrophilous species, thriving in habitats enriched by nitrogen compounds, such as those near bird roosting sites, agricultural areas, and urban zones. It is highly tolerant of air pollution and is frequently used as a bioindicator in ecological studies. The IUCN lists this species as Least Concern given its broad distribution and tolerance of disturbed environments. As a lichen, it is a mutualistic association between a fungal partner and algal or cyanobacterial photobionts. Biological traits such as growth rates, lifespan, and dietary ecology remain poorly documented in standardized databases for lichen species.
