Habitat & Geographic Range

Chupire

Habitat

Typically found in diverse terrestrial habitats from tropical forests to temperate regions.

Common Kidney-Vetch

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, temperate broadleaf and mixed forests, and temperate coniferous forests, among 6 distinct biome types spanning the Indomalayan and Oceanian and Palearctic realms. Populations are also found in montane and highland environments at higher elevations.

Range

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

Chupire

Chupire (Euphorbia calyculata) is a succulent or semi-succulent plant in the large family Euphorbiaceae, found in tropical and subtropical dry habitats of Mesoamerica and northern South America including Venezuela. The genus Euphorbia is one of the most species-rich genera of flowering plants, encompassing an enormous range of growth forms from tiny annual herbs to massive succulent trees, united by the presence of a milky, toxic latex and a specialized inflorescence called the cyathium. E. calyculata grows as a shrub or small tree in dry to seasonally dry tropical environments, contributing to the structure of thornscrub, dry forest edges, and rocky hillside vegetation. The Chupire is assessed as Least Concern by the IUCN, indicating stable populations within its native range. Its latex, like that of many Euphorbias, contains diterpene esters and other irritant compounds that deter herbivory. In some regions, the plant has traditional uses in folk medicine and as living fences or hedgerows, exploiting its branching structure and drought tolerance. The species contributes to the floristic diversity of Neotropical dry vegetation, a biome under increasing pressure from agricultural expansion and climate-driven aridity.

Common Kidney-Vetch

Common Kidney-Vetch (<em>Anthyllis vulneraria</em>) is a flowering plant in the legume family Fabaceae, assessed as Vulnerable on the IUCN Red List due to habitat degradation and agricultural intensification across parts of its range. It is widely distributed across Africa (Libya), Asia (Japan), Europe (nine countries), North America (Canada and the United States), and Oceania (Australia), occupying six distinct biome types and occurring within the Indomalayan and Oceanian biogeographic realms. The species typically grows in dry, calcareous grasslands, coastal cliffs, sand dunes, and rocky slopes, often favoring nutrient-poor soils. It is an important larval food plant for certain butterfly species, particularly the Small Blue butterfly in Europe, and contributes to soil fertility through nitrogen fixation via root nodules. Its cheerful yellow, orange, or red flower heads make it a recognizable component of chalk and limestone grassland communities. Biological traits of this species remain poorly documented in the scientific literature.
