Habitat & Geographic Range

Cochran's False Brook Salamander

Habitat

Typically found in freshwater habitats, moist forests, and wetlands.

Range

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

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.

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.

Cochran's False Brook Salamander

Cochran's false brook salamander (Pseudoeurycea cochranae) is a small, slender plethodontid salamander endemic to the pine-oak and cloud forests of the eastern Sierra Madre Occidental and adjacent ranges of Mexico. Like all members of the family Plethodontidae, it is lungless — respiration occurs entirely through moist skin and mucous membranes of the mouth, constraining the species to damp microhabitats such as mossy rock faces, rotting logs, and the leaf litter layer in humid montane forest. The species is direct-developing, laying small clutches of eggs in moist terrestrial sites from which miniature fully formed salamanders emerge, bypassing the aquatic larval stage characteristic of most other amphibian orders. Pseudoeurycea cochranae is a nocturnal forager, preying on small invertebrates including collembolans, mites, and small beetles encountered during nightly activity in its humid forest microhabitat. The species is classified as Vulnerable by the IUCN owing to its limited distribution, continuing deforestation driven by logging, agricultural conversion, and human settlement in its montane range, and susceptibility to climate-driven shifts in the moisture regime of cloud forest habitats. The genus Pseudoeurycea is largely endemic to Mexico and comprises several dozen species, many of which are similarly threatened. Like several congeners, P. cochranae is named in honour of Doris Mable Cochran. Population monitoring in its restricted range is an ongoing conservation priority.

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.
