Found in Norway. Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Common Motherwort

Common Motherwort (<em>Leonurus cardiaca</em>) is a perennial herbaceous plant in the genus <em>Leonurus</em>, family Lamiaceae. It is widely distributed across Asia, Europe, North America, and Oceania, with confirmed presence in countries including Australia, Belarus, Belgium, Bulgaria, and Canada, as well as Japan and 19 European nations. The species is typically found in diverse terrestrial habitats from tropical forests to temperate regions, commonly occurring in hedgerows, roadsides, disturbed ground, and open woodland edges. Currently listed as Near Threatened on the IUCN Red List, Common Motherwort requires ongoing monitoring to prevent further population decline. As a member of the mint family, it produces whorls of small pink or white flowers along an upright stem, and bears distinctively lobed leaves. It has a long history of use in traditional medicine, particularly in European and Chinese herbal traditions, where it has been employed for cardiovascular and women's health applications. The species name <em>cardiaca</em> reflects this cardiac association. Specific biological measurements such as lifespan and dimensions are not documented in available records.

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.
