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.

Range

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

Common Birdwing

The common birdwing (<em>Troides helena</em>) is a large and striking butterfly of the family Papilionidae, classified as Least Concern on the IUCN Red List. It inhabits terrestrial and freshwater environments across its range in South and Southeast Asia. <em>Troides helena</em> is among the larger birdwing butterflies, with males displaying vivid yellow and black coloration on the hindwings, while females are typically larger and more cryptically marked. The species is often found in tropical and subtropical forest habitats, where it visits flowering plants for nectar. Larvae of birdwing butterflies typically feed on Aristolochia vines, which contain toxic alkaloids that are sequestered by the caterpillars and retained in adult tissues as a chemical defense. Despite its Least Concern status, birdwing butterflies are subject to trade regulations due to their attractiveness to collectors. Biological traits of this species remain poorly documented in the scientific literature.

Polar bear

O maior carnivoro terrestre da Terra, o urso-polar pode ultrapassar 700 kg e e encontrado pelo gelo marinho artico, do Canada ate a Russia. Mamiferos marinhos altamente especializados que dependem do gelo marinho para cacas de focas e focas-barbadas. Excelentes nadadores capazes de percorrer grandes distancias em aguas abertas. Classificado como Vulneravel, com populacoes sob severa pressao devido a rapida perda de gelo marinho artico causada pelas mudancas climaticas.
