Ciliate Crystalwort

Ciliate crystalwort (Riccia crozalsii) is a thalloid liverwort in the family Ricciaceae, classified as Vulnerable in Europe. It grows as a flat, strap-like or rosette-forming thallus, typically in damp, disturbed or ephemeral habitats such as the margins of seasonal pools, rutted tracks, and temporarily flooded ground with sparse vegetation cover. The species is characterized by thallus margins fringed with fine cilia-like teeth, which give it its common name. Riccia crozalsii is found in Mediterranean and Atlantic regions of Europe, with records from Spain, Portugal, France, Italy, and parts of the British Isles, though populations are generally sparse and localized. It tends to appear in winter and spring when suitable wet conditions prevail, and the thallus desiccates or disappears during dry summer months. The species is assessed as Vulnerable due to the loss and degradation of its specialized ephemeral wetland habitats, driven by drainage, agricultural intensification, and altered hydrological regimes across Europe. As with many liverworts dependent on wet, open habitats, Riccia crozalsii has experienced declines in regions where traditional low-intensity land management practices have been abandoned. Monitoring and protection of ephemeral pool and wetland margins are key conservation actions for this species.

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.
