Lecanographa lyncea es un liquen crustáceo raro que crece sobre la corteza de árboles veteranos y añosos en bosques antiguos. Produce apotecios lirelados alargados y se considera uno de los indicadores más sensibles de ecosistemas forestales no perturbados de larga continuidad en Europa. Clasificado como En Peligro Crítico, enfrenta graves amenazas por la pérdida de hábitat, el declive de árboles veteranos y la contaminación atmosférica.

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.
