Eisbär

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.

Achlya bisexualis is an oomycete in the family Saprolegniaceae that decomposes organic matter in freshwater habitats and can act as a pathogen of fish and invertebrates under certain conditions. It exhibits a fascinating pheromone-based sexual reproduction system that has been extensively studied as a model for steroid hormone signaling in lower eukaryotes. Its mycelial colonies rapidly colonize dead insect and plant debris in slow-moving water.

Eisbär

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.
