Typically found in virtually all terrestrial and freshwater habitats.

Range

Found across Europe (5 countries) and North America (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 Flower Fly

<em>Syrphus ribesii</em> is a hoverfly in the family Syrphidae, order Diptera, commonly known as the common flower fly. This species is among the most frequently encountered hoverflies in its range and serves an important ecological role as a pollinator of flowering plants. The species is classified as Least Concern on the IUCN Red List. <em>Syrphus ribesii</em> is distributed across Europe and the United States, typically inhabiting gardens, hedgerows, woodland edges, and meadows where flowering plants are abundant. Adults are characterized by yellow and black banded abdomens that mimic the appearance of wasps or bees, providing protection from predators through Batesian mimicry. Adults feed on nectar and pollen, while larvae are predatory, feeding on soft-bodied insects such as aphids and thereby providing a natural pest control service in gardens and agricultural settings. The species is migratory in parts of its range. Biological traits of this species remain poorly documented in the scientific literature.

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.
