Habitat & Geographic Range

Clover Dodder

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, montane grasslands and shrublands, and Mediterranean forests and woodlands, among 8 distinct biome types spanning the Afrotropic and Neotropic and Palearctic realms. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Africa (South Africa), Europe (9 countries), North America (Canada, United States), Oceania and the Pacific (Australia), and South America (Argentina, Venezuela). Currently classified as Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.

Alondra Común

Habitat

Found across multiple habitat types including temperate broadleaf and mixed forests, tundra, and tropical and subtropical moist broadleaf forests spanning the Australasia and Oceanian realms.

Range

Widely distributed across Europe (5 countries), North America (Canada, United States), and Oceania and the Pacific (Australia, New Zealand). Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

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.

Alondra Común

Célebre en la literatura y poesía europea por su complejo y melodioso canto interpretado en vuelo durante espectaculares vuelos de exhibición, la alondra común (Alauda arvensis) asciende verticalmente cientos de metros sobre campos abiertos, praderas y brezales de Europa y Asia mientras produce un torrente ininterrumpido de canto que puede durar hasta una hora. Los machos pueden producir más de 700 frases de canto distintas. Antaño enormemente abundante en los campos europeos, las poblaciones de alondras han disminuido más del 70% desde 1970 debido a la intensificación agrícola.
