Fly Agaric

El matamoscas (Amanita muscaria) es uno de los hongos más icónicos y reconocibles de la Tierra, con llamativos sombreros rojos con manchas blancas en los bosques boreales del hemisferio norte. A pesar de su apariencia de cuento de hadas, contiene potentes compuestos psicoactivos como muscimol y ácido iboténico y es moderadamente tóxico. Forma simbiosis micorrícicas esenciales con abedules, pinos y abetos, intercambiando nutrientes minerales por carbono y desempeñando roles fundamentales en el ciclo de nutrientes de los bosques boreales.

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.
