Clustered Stonewort

Tolypella glomerata, the clustered stonewort, is a charophyte alga in the family Characeae, found in calcareous, nutrient-poor freshwater habitats including lakes, ponds, ditches, and slow-flowing water in northwestern and northern Europe. Charophytes are macroscopic green algae with a distinctive whorl-like arrangement of branches and a complex, plant-like structure that distinguishes them from other algae. T. glomerata is encrusted with calcium carbonate deposits (hence 'stonewort'), giving it a pale, grey-green appearance and rough texture. The species colonizes clear, low-nutrient water over fine sediment or gravel substrates where competition from vascular plants is reduced by nutrient limitation. It is listed as Vulnerable by the IUCN, reflecting significant declines driven by eutrophication (nutrient enrichment from agriculture and sewage), which promotes the growth of vascular plants and phytoplankton that shade out stoneworts. Drainage, water abstraction, and peat cutting also threaten its habitats. Charophyte diversity has declined substantially across lowland Europe and North America over the past century, with many species becoming locally extinct from sites they once colonized.

아메리카 대륙에서 가장 큰 고양잇과 동물로, 체중이 최대 100kg에 달하며 단단하고 근육질의 체형과 특유의 로제트 무늬 털가죽을 지닌다. 멕시코에서 남아메리카까지 분포하며, 아마존과 판타날이 주요 서식지다. 뛰어난 수영 실력을 갖춘 최상위 포식자로, 먹이 개체수 조절에 핵심적 역할을 한다. 산림 벌채로 인해 서식 범위가 줄어들어 준위협종으로 분류된다.
