Range

Distributed across Portugal, Sweden, and United States.

Oso Polar

Habitat

Found across multiple habitat types including temperate broadleaf and mixed forests, temperate coniferous forests, and boreal forests and taiga, among 4 distinct biome types within the Palearctic biogeographic realm. Populations are also found in montane and highland environments at higher elevations.

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

Common brighteyes

Common brighteyes (<em>Reichardia picroides</em>) is a perennial herb species found in Portugal, Sweden, and the United States, typically inhabiting diverse terrestrial environments across its range. As a member of the family Asteraceae, this species often produces yellow dandelion-like flowerheads and is commonly found in open, dry, and disturbed habitats such as roadsides, waste ground, and coastal areas. The common brighteyes has not been formally evaluated on the IUCN Red List. Originally native to the Mediterranean basin and parts of the Middle East, the species has spread to numerous other regions where it is considered naturalized. It typically grows in well-drained soils in full sunlight, showing a preference for rocky or sandy substrates in coastal and inland locations. The species is often associated with ruderal habitats and represents an adaptable pioneer in disturbed ecosystems. 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.
