Habitat & Geographic Range

Big Finner

Habitat

Found across multiple habitat types including tropical and subtropical dry broadleaf forests, flooded grasslands and savannas, and montane grasslands and shrublands, among 4 distinct biome types within the Neotropic biogeographic realm.

Range

Widely distributed across Asia (Taiwan), Europe (5 countries), and South America (Colombia, Ecuador, Venezuela). Currently classified as Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.

Common wireweed

Habitat

Inhabits deserts and xeric shrublands within the Afrotropic biogeographic realm. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Africa (18 countries), Asia (18 countries), Europe (Spain), North America (4 countries), Oceania and the Pacific (12 countries), and South America (Brazil, Colombia).

Big Finner

Big Finner (Balaenoptera physalus) is classified as Endangered (EN) on the IUCN Red List. At high risk of extinction in the wild, with significant population decline and ongoing threats to survival.

Common wireweed

<em>Sida acuta</em>, commonly known as common wireweed or broom jute, is a small woody-based shrub in the family Malvaceae. Its conservation status is listed as Not Evaluated by the IUCN. The species has an extremely broad distribution spanning Africa, Asia, Europe, the Americas, and Oceania, reflecting its status as both a native species in parts of tropical and subtropical regions and a widely naturalized weed in disturbed habitats globally. It typically grows in roadsides, cultivated fields, waste ground, and degraded grasslands in warm climates, often colonizing disturbed and compacted soils where few other plants thrive. <em>Sida acuta</em> is a branching perennial shrub typically reaching 50–100 cm in height, with lance-shaped toothed leaves, small pale yellow five-petaled flowers, and distinctive star-shaped stellate hairs on stems and leaves. The plant produces schizocarp fruits that split into individual hard segments each bearing a seed, facilitating dispersal by animals, water, and machinery. Several parts of the plant are used in traditional medicine across its range for treating a variety of conditions. Biological traits including average lifespan, precise height, and mass remain poorly documented in standardized databases. Ecologically, common wireweed is considered an invasive species in many regions, but also provides small-scale cover and foraging habitat for invertebrates in disturbed environments throughout its vast pantropical and warm-temperate global distribution.
