Habitat & Geographic Range

Buckelwal

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical dry broadleaf forests, and tropical and subtropical grasslands and savannas, among 11 distinct biome types. Populations are also found in montane and highland environments at higher elevations.

Range

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

Coarse Stained-glass Leafhopper

Habitat

Inhabits temperate broadleaf and mixed forests and deserts and xeric shrublands within the Palearctic biogeographic realm.

Range

Found in Azerbaijan. Currently classified as Critically Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.

Buckelwal

Among the most acrobatic of the great whales, humpback whales are renowned for their complex, haunting songs sung by males during breeding season — some lasting hours and evolving over time. Reaching 16 meters and 30 tonnes, they undertake the longest migrations of any mammal. Found in all oceans, humpbacks feed on krill and small fish using cooperative bubble-net feeding. Populations have largely recovered from historic whaling.

Coarse Stained-glass Leafhopper

Argaterma alticola, the coarse stained-glass leafhopper, is a critically endangered hemipteran insect in the family Cicadellidae, known only from a highly restricted distribution in Azerbaijan. Leafhoppers in this family are small, typically fast-moving plant-feeding insects that suck phloem sap from their host plants and can be economically significant in agricultural contexts. Argaterma alticola is associated with montane or high-altitude grassland or scrub vegetation in the Caucasus region, where its highly localized range makes it exceptionally vulnerable to habitat alteration. The Critically Endangered assessment reflects the tiny known range, presumed small population size, and threats from overgrazing, agricultural intensification, and climate-driven vegetation shifts in the Caucasus mountain systems. The family Cicadellidae is among the most species-rich families of insects globally, with over 20,000 described species, but many specialized species with restricted ranges remain poorly studied and face extinction before they can be formally surveyed. Conservation of this species depends on identifying and protecting the specific grassland habitats in Azerbaijan where it persists and understanding its host plant associations and population size.
