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.

Xylaria corniformis es un ascomiceto carbonáceo en forma de maza que produce estrómalos negros, firmes, en forma de cuerno o asta de ciervo, sobre madera en descomposición en hábitats forestales tropicales y subtropicales. Es un descomponedor saprotrófico de la madera que contribuye a la degradación de la lignocelulosa en los ecosistemas forestales. Clasificado como En Peligro, las amenazas incluyen la deforestación tropical y la pérdida de hábitats de bosque antiguo.
