Habitat & Geographic Range
Common Pin Spiderhead
Typically found in diverse terrestrial habitats from tropical forests to temperate regions.
Polar bear
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.
Found in Norway. Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.
Common Pin Spiderhead
<em>Serruria fasciflora</em>, the common pin spiderhead, is a shrub in the family Proteaceae endemic to the Cape Floristic Region of South Africa, one of the world's most species-rich botanical hotspots. It produces delicate, feathery flowerheads with slender bracts and small florets arranged in a clustered inflorescence that gives the plant its evocative common name. Like other members of the genus Serruria, it is adapted to the nutrient-poor, acidic, well-drained soils of the fynbos biome, where it coexists with a highly diverse array of flowering plants and depends on specialised pollinators including bees and flies. <em>Serruria fasciflora</em> is fire-adapted in accordance with the natural disturbance regime of fynbos, typically regenerating from seed following periodic burns. The species is assessed as Least Concern on the IUCN Red List, though the broader fynbos biome faces significant pressures from invasive alien plants, agricultural conversion, urban sprawl, and inappropriate fire management. Biological traits such as average plant lifespan, typical shrub dimensions, and detailed reproductive biology remain poorly documented in the scientific literature. Conservation of the species depends on the maintenance of intact, functioning fynbos habitat across the Cape Floristic Region.
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.
