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.

Tricholoma frondosae es un hongo robusto y fibroso relacionado con los tricholomas, con un sombrero gris pardo y una asociacion con los abedules. Crece en bosques dominados por abedules y en bosques de frondosas mixtos del norte de Europa y zonas templadas. Este hongo ectomicorrizico forma asociaciones mutualistas con los sistemas radiculares del abedul.
