Habitat & Geographic Range

Holzfliege

Habitat

Typically found in virtually all terrestrial and freshwater habitats.

Range

Distributed across Belgium, Denmark, Norway, and Sweden.

Westlicher Gorilla

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical grasslands and savannas, and flooded grasslands and savannas, among 4 distinct biome types within the Afrotropic biogeographic realm. Populations are also found in montane and highland environments at higher elevations.

Range

Distributed across Cameroon, Congo (Republic), Equatorial Guinea, and Gabon. Currently classified as Critically Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.

Holzfliege

<em>Xylophagus ater</em>, commonly known as the Common Awl Fly, is a dipteran insect in the family Xylophagidae. This species is assessed as Least Concern on the IUCN Red List and is distributed across parts of northern and western Europe, with records from Belgium, Denmark, Norway, and Sweden. The larvae of Common Awl Flies are typically found in decaying wood and moist, rotting logs, where they develop as predators of other wood-inhabiting invertebrate larvae. This saproxylic association makes the species dependent on the availability of large-diameter deadwood in forest habitats. Adults are slender, dark flies resembling small robber flies, and they are typically encountered in woodland environments near their larval habitats. As saproxylic insects, Common Awl Flies play an important role in forest nutrient cycling by contributing to the decomposition of dead wood. Their presence in a habitat often indicates a relatively undisturbed forest ecosystem with sufficient deadwood resources. Biological traits of this species remain poorly documented in the scientific literature.

Westlicher Gorilla

The world's largest primate, western gorillas weigh up to 180 kg and inhabit the tropical and subtropical forests of equatorial Africa. Primarily herbivorous, living in family groups led by a silverback male who protects the troop and mediates social conflicts. Critically Endangered, with populations threatened by deforestation, poaching for bushmeat, and outbreaks of Ebola virus disease.
