Common Pipsissewa

<em>Chimaphila umbellata</em>, the common pipsissewa or prince's pine, is an evergreen subshrub in the family Ericaceae, characterised by whorled, toothed, leathery leaves and nodding, waxy pink to white flowers borne in small clusters on slender stems. It typically grows in dry to moist coniferous and mixed forests, often in humus-rich soils with a dense duff layer, where it depends on mycorrhizal associations for nutrient uptake. The species is distributed across Europe, including Belgium, Denmark, Finland, France, and the Netherlands, and in North America including the United States, reflecting a circumboreal distribution pattern. <em>Chimaphila umbellata</em> is assessed as Endangered on the IUCN Red List, indicating significant population declines attributed to habitat loss through forest conversion, fire suppression altering forest structure, and disruption of fungal symbiont communities. It is a slow-growing, long-lived plant with limited capacity for rapid recovery following disturbance. Biological traits such as precise average lifespan, plant dimensions, and detailed dietary and physiological parameters remain poorly documented in the scientific literature. The plant has a history of use in traditional herbal medicine among Indigenous North American peoples, who used it to treat kidney and urinary conditions.

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.
