Common Grass-veneer

<em>Agriphila tristellus</em>, commonly known as the common grass veneer, is a small moth belonging to the genus Agriphila within the family Crambidae. This species occupies virtually all terrestrial and freshwater habitats, suggesting a broad ecological tolerance within its range. Its documented distribution includes Belgium, Denmark, Norway, and Sweden, indicating a range centered on northwestern and Scandinavian Europe. The species is assessed as Least Concern on the IUCN Red List, reflecting stable population status across its range. Common grass veneer moths typically inhabit grasslands and rough vegetation where larval foodplants are available. Biological traits of this species remain poorly documented in the scientific literature.

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.
