Chroococcus turicensis is a species of cyanobacteria in the family Chroococcaceae, with the specific epithet turicensis referring to Turicum, the Latin name for the city of Zurich, Switzerland, suggesting that the species was first described or commonly documented from Swiss freshwater habitats. Chroococcus species are small, coccoid cyanobacteria occurring in pairs or tetrads within gelatinous sheaths in freshwater and moist environments. Chroococcus turicensis has been recorded from lakes and other freshwater localities in central Europe, including the alpine and pre-alpine lakes of Switzerland. Alpine and subalpine freshwater bodies are generally oligotrophic, and the cyanobacteria that inhabit them tend to be well adapted to low nutrient concentrations and clear, well-lit waters. The freshwater phytoplankton of Alpine lakes has been extensively studied due to the ecological and economic importance of these water bodies as drinking water reservoirs and indicators of environmental change. Chroococcus turicensis contributes to the diversity of the cyanobacterial component of such communities. Like all Chroococcus species, it is a prokaryote whose conservation status has not been assessed by the IUCN.

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.
