Habitat & Geographic Range

Common teatree

Habitat

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

Range

Distributed across Congo (DRC) and United States.

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 teatree

<em>Leptospermum petersonii</em>, the lemon-scented teatree, is a shrub or small tree in the family Myrtaceae, native to eastern Australia but noted in distribution records including the Democratic Republic of Congo and the United States, reflecting its cultivation and occasional naturalization in tropical and subtropical regions. It is classified as Least Concern on the IUCN Red List. The plant is prized for its strongly lemon-scented foliage, which yields an essential oil used in perfumery and aromatherapy. It typically grows as a dense, multi-stemmed shrub reaching 3–6 meters tall, bearing small, narrow leaves and white or pale pink five-petaled flowers. Like other teatrees, it is adapted to well-drained, often nutrient-poor soils and full sun conditions. The flowers attract bees and other pollinators. It is sometimes cultivated as an ornamental and for essential oil production. Biological traits such as precise lifespan, seed output, and biomass measurements remain poorly documented in standardized scientific assessments for this species.

Polar bear

The largest land carnivore on Earth, polar bears can exceed 700 kg and are found across Arctic sea ice from Canada to Russia. Highly specialized marine mammals that rely on sea ice to hunt ringed and bearded seals. Excellent swimmers capable of covering vast distances in open water. Listed as Vulnerable, with populations under severe pressure from rapid Arctic sea ice loss due to climate change.
