Clover Dodder

Clover dodder (Cuscuta epithymum) is a parasitic flowering plant in the family Convolvulaceae, a leafless, twining vine that obtains all its water and nutrients from host plants via haustoria — specialized penetrating organs that connect to host vascular tissue. The species is almost entirely dependent on its hosts throughout its life, with only brief photosynthetic activity during germination before establishing parasitic connections. C. epithymum parasitizes a wide range of host species including clover (Trifolium), gorse (Ulex), heathers (Erica, Calluna), thyme (Thymus), and other plants in open heathland, grassland, and scrub habitats. The stems are thread-like, yellowish-pink or reddish, and support clusters of small white to pale pink flowers. Originally widespread across Europe, Asia, North Africa, and the Americas, the species has declined significantly in many parts of its range due to agricultural intensification, herbicide application, grassland conversion, and loss of semi-natural heathlands. It is currently listed as Endangered on the IUCN Red List, reflecting population decline across its European core range. Conservation of C. epithymum requires the maintenance of unimproved, low-nutrient grasslands and heathlands that support its diverse host plant communities. The species is recorded from Africa, Europe, North America, Oceania, and South America, though populations in some regions represent introductions associated with contaminated legume seed lots.

유럽수달(Lutra lutra)은 유럽과 아시아 전역의 깨끗한 강, 개울, 해안선에 서식하는 날렵한 반수생 족제비과 동물입니다. 체장 최대 1.3미터에 달하며 민감한 수염으로 먹이의 움직임을 감지해 물고기를 사냥하는 뛰어난 능력을 가지고 있습니다. 풍부한 물고기가 있는 오염되지 않은 물이 필요하여 담수 생태계 건강의 지표종으로 알려져 있습니다. 한때 사냥과 오염으로 서유럽에서 거의 멸종 위기에 처했지만, 수질 개선 이후 개체수가 크게 회복되었습니다.
