Habitat & Geographic Range

Common sawfly

Habitat

Typically found in virtually all terrestrial and freshwater habitats.

Range

Distributed across Canada, Norway, Sweden, 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 sawfly

<em>Allantus basalis</em> is a sawfly species within the family Tenthredinidae, order Hymenoptera, native to temperate regions of North America and Scandinavia, including records from Canada, Norway, Sweden, and the United States. As a member of the subfamily Allantinae, this species is part of a broadly distributed group of plant-associated insects. Adults are typically small, dark-bodied insects resembling stout wasps, and larvae are known to feed on the foliage of their specific host plants, though the precise host associations for this species remain incompletely characterized in the literature. <em>Allantus basalis</em> inhabits woodland margins, shrubby areas, and vegetated habitats across its range where suitable host plants occur. The species has not been assessed by the IUCN, and its conservation status is therefore listed as Not Evaluated. Biological traits for this species remain poorly documented in the scientific literature, including data on average lifespan, body size, weight, and specific dietary composition. Population trends are currently unknown, and the species does not appear to face significant recognized threats at this time.

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.
