Habitat & Geographic Range

Cheetah

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 9 distinct biome types spanning the Afrotropic and Palearctic realms. Populations are also found in montane and highland environments at higher elevations.

Range

Distributed across Botswana, Iran, Kenya, Namibia, and Tanzania. Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Habitat

Native to Asia, inhabiting ecosystems characteristic of the region.

Range

Found in Taiwan.

Cheetah

The fastest land animal on Earth, reaching speeds of 112 km/h over short distances across African and Iranian grasslands. Slender build with a deep chest, long legs, and distinctive black tear-stripe markings. Unlike other big cats, cheetahs vocalize with chirps and purrs. Vulnerable, with only ~7,000 remaining due to habitat fragmentation and competition with larger predators.

Chitinophaga taiwanensis is a species of Gram-negative, aerobic bacterium belonging to the genus Chitinophaga in the family Chitinophagaceae. As the specific epithet indicates, this species was first described from soil samples collected in Taiwan. Like all members of Chitinophaga, it possesses the enzymatic machinery to degrade chitin — the structural polysaccharide abundant in fungal cell walls, insect cuticles, and crustacean shells — making it a key participant in the terrestrial nitrogen and carbon cycles. The genus is characterised by gliding motility on semi-solid or solid surfaces, production of pigmented colonies (typically yellow, orange, or tan), and a strictly aerobic metabolism. C. taiwanensis thrives in the rich agricultural and subtropical soils of Taiwan and similar environments, where the turnover of fungal biomass and arthropod debris provides abundant chitin substrate. Research on Chitinophaga species from tropical and subtropical soils has advanced understanding of chitinolytic enzyme diversity and its applications in biocontrol of soil-borne fungal diseases affecting crops. As a bacterium, Chitinophaga taiwanensis is not assessed under IUCN Red List criteria, which are designed for animals, plants, fungi, and other eukaryotes. The species' ecological significance lies in its contribution to soil health, organic matter decomposition, and nitrogen mineralisation in agricultural and natural ecosystems.
