closed-sheathed cottongrass

Closed-sheathed cottongrass is a sedge in the genus Eriophorum (family Cyperaceae) characterized by leaf sheaths that are fused to form a closed tube around the stem, a morphological feature distinguishing it from open-sheathed relatives. Cottongrasses are quintessential plants of northern peatlands, bogs, and acidic fens across the boreal and arctic zones of the Northern Hemisphere, producing conspicuous cottony white seed heads — modified perianth bristles elongating as fruits mature — that transform peat bogs into spectacular white-tufted landscapes in late spring and early summer. These plants are ecological keystones of Sphagnum-dominated peat bogs, contributing organic matter through their dense root systems that resist decomposition in waterlogged, oxygen-depleted conditions, driving peat formation over millennia. Eriophorum species serve as important food plants for ptarmigan, geese, and various invertebrates in arctic and subarctic ecosystems. Climate change threatens cottongrass habitats through warmer temperatures accelerating peat decomposition, altered hydrological regimes, and permafrost thaw that fundamentally transforms the structure of northern peatlands.

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.
