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 Blue-sow-thistle

The common blue sow-thistle (<em>Lactuca macrophylla</em>) is a plant species native to Europe, with documented occurrences in the Czech Republic, Denmark, France, Iceland, and Norway. This species typically inhabits diverse terrestrial environments, adapting to a range of ecological conditions across its European range. As a member of the family Asteraceae, it often grows in disturbed habitats, roadsides, and woodland edges throughout its native range. The common blue sow-thistle has not been formally assessed on the IUCN Red List, so its global conservation status remains unevaluated at this time. This species typically forms part of the understory vegetation in temperate ecosystems. Its broad distribution across northern and central Europe suggests a degree of ecological resilience and adaptability to varying climatic conditions. Biological traits of this species remain poorly documented in the scientific literature.
