Clubbed General

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.

Oso Polar

Habitat

Found across multiple habitat types including temperate broadleaf and mixed forests, temperate coniferous forests, and boreal forests and taiga, among 4 distinct biome types within the Palearctic biogeographic realm. Populations are also found in montane and highland environments at higher elevations.

Clubbed General

Stratiomys chamaeleon is a soldier fly in the family Stratiomyidae, commonly known as the clubbed general. It is a large, distinctive fly with wasp-like yellow and black banding on the abdomen, giving it an aposematic appearance. Adults are frequently observed visiting flowers for nectar and pollen in wet meadows, marshes, and fens, particularly in western and northern Europe. The species is associated with wetland habitats, where larvae develop aquatically or semi-aquatically in waterlogged soils, mud, decaying organic matter near water margins, and occasionally in dung. Larvae are elongated, flat-bodied, and breathe via a respiratory siphon at the tail end. Adults are strong fliers capable of covering considerable distances between habitat patches. Stratiomys chamaeleon is considered Near Threatened, reflecting the significant loss and degradation of wet grassland and fen habitats across Europe due to drainage for agriculture, peat extraction, and development. The species requires mosaics of open water, wet soil, and flowering plants to complete its life cycle. Conservation depends on wetland restoration and maintenance of traditional wet meadow management.

Oso Polar

El mayor carnivoro terrestre de la Tierra, el oso polar puede superar los 700 kg y se encuentra en el hielo marino del Artico, desde Canada hasta Rusia. Es un mamifero marino altamente especializado que depende del hielo marino para cazar focas anilladas y barbadas. Excelente nadador capaz de cubrir grandes distancias en agua abierta. Clasificado como Vulnerable, sus poblaciones soportan una presion severa por la rapida perdida de hielo marino artico debida al cambio climatico.
