Habitat & Geographic Range

Common Sundew

Habitat

Typically found in diverse terrestrial habitats from tropical forests to temperate regions.

Range

Widely distributed across Asia (Taiwan), Europe (8 countries), and North America (Canada, United States). Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Polar bear

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.

Range

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

Common Sundew

<em>Drosera rotundifolia</em>, the common sundew, is a carnivorous flowering plant in the family Droseraceae, order Caryophyllales. It has a broad distribution spanning Europe, Asia, and North America, typically growing in sphagnum bogs, wet heathlands, and other nutrient-poor, acidic wetland habitats where it compensates for low soil nutrient availability by trapping and digesting insects. The round leaves bear red, glandular tentacles tipped with sticky mucilage that immobilize prey, which is then digested by enzymes secreted from the leaf surface. <em>Drosera rotundifolia</em> produces small white flowers on a slender scape, pollinated by insects. It plays a minor but ecologically interesting role in controlling insect populations within its boggy habitat. Biological traits including typical individual lifespan, precise leaf dimensions, and detailed prey composition remain poorly documented. The species is assessed as Vulnerable by the IUCN, reflecting significant population declines across much of its range driven primarily by drainage and destruction of peatland habitats, atmospheric nitrogen deposition, and climate change altering the hydrology of bog ecosystems. Effective peatland conservation is critical for the long-term survival of this species.

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.
