Habitat & Geographic Range

baleine à bosse

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.

Common Orange Legionnaire

Habitat

Typically found in virtually all terrestrial and freshwater habitats.

Range

Distributed across Belgium, Denmark, Norway, and Sweden. Listed as Near Threatened, this species requires ongoing monitoring to prevent population decline.

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.

Common Orange Legionnaire

<em>Beris vallata</em> is a soldier fly in the family Stratiomyidae, known from Belgium, Denmark, Norway, and Sweden in northern Europe. The species inhabits a broad range of terrestrial and freshwater environments, including woodland edges, hedgerows, stream margins, and moist meadows where decaying organic matter supports larval development. Larvae of Beris species typically develop in rotting wood, leaf litter, damp soil, or organic debris, while adults are often found visiting flowers for nectar and pollen. The IUCN classifies this species as Near Threatened, indicating that it faces meaningful risk factors that could elevate its status if current trends continue. Pressures likely include habitat degradation, loss of traditional woodland management practices, and the decline of dead wood microhabitats essential for larval stages. The species has a restricted distribution confined to northern European countries and may be sensitive to changes in woodland structure and composition. Biological traits such as average lifespan, body length, body weight, and detailed dietary studies remain poorly documented in standardized ecological databases for this dipteran species. Continued monitoring of woodland habitats across its range is important for its long-term conservation.
