Widely distributed across Europe (5 countries), North America (Canada, United States), and Oceania and the Pacific (Australia, New Zealand). Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

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.

ヒバリ

ヒバリ（Alauda arvensis）は、飛翔中に歌う複雑で美しい声でヨーロッパの文学と詩に称えられてきました。ヨーロッパとアジア全域の開けた農地、草地、荒野の上空を数百メートルも垂直に舞い上がりながら、最長1時間にわたって途切れなく歌い続けます。雄は700種類以上の独特なさえずりを発することができます。かつてヨーロッパの農地で非常に多かったヒバリの個体数は、農業の集約化により1970年代から70%以上減少しています。
