Oso Polar

El mayor carnivoro terrestre de la Tierra, el oso polar puede superar los 700 kg y se encuentra en el hielo marino del Artico, desde Canada hasta Rusia. Es un mamifero marino altamente especializado que depende del hielo marino para cazar focas anilladas y barbadas. Excelente nadador capaz de cubrir grandes distancias en agua abierta. Clasificado como Vulnerable, sus poblaciones soportan una presion severa por la rapida perdida de hielo marino artico debida al cambio climatico.

Pyrenula nitida es un liquen crustaceo corticola que produce un talo liso y brillante de color verde oliva a marron, con peritecios en forma de frasco incrustados en la corteza lisa de arboles antiguos de hoja ancha en bosques atlanticos humedos. Se considera una especie indicadora emblematica de bosques antiguos con larga continuidad en Europa occidental. En peligro, este liquen esta gravemente amenazado por la perdida de arboles veteranos y habitats de bosque antiguo.
