coastal quillwort

Coastal quillwort (Isoetes maritima) is an aquatic or semi-aquatic lycophyte in the family Isoetaceae, native to Atlantic coastal regions of North America and western Europe, including eastern Canada, the northeastern United States, Ireland, the United Kingdom, and northern France. It grows in shallow brackish or slightly saline pools, coastal lagoons, rock crevices, and wet hollows that experience seasonal drying. Like all Isoetes species, it has quill-like leaves arising from a corm-like base and reproduces via spores produced in sporangia embedded at leaf bases. Coastal quillwort occupies a specialised niche at the intersection of marine and freshwater habitats, tolerating fluctuating salinity levels. Its populations are often small and localised, making them vulnerable to habitat modification, drainage, and coastal development. The IUCN assesses coastal quillwort as Least Concern overall, but many regional populations are protected or listed as threatened. As an ancient lineage of vascular plants, Isoetes species represent living relicts of the Carboniferous-era lycopsid forests and hold significant evolutionary interest for botanists.

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.
