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 sancti is a soil-dwelling bacterium within the genus Chitinophaga, family Chitinophagaceae, phylum Bacteroidota. The genus Chitinophaga encompasses a diverse group of Gram-negative, aerobic, rod-shaped to filamentous bacteria with a defining metabolic hallmark: the ability to degrade chitin using secreted chitinase enzymes. Chitin is a ubiquitous biopolymer in terrestrial and aquatic ecosystems, forming the structural component of fungal cell walls, nematode egg shells, and insect and crustacean exoskeletons. By mineralising chitin, Chitinophaga species play an indispensable role in releasing bound nitrogen and carbon back into bioavailable forms in the soil. C. sancti, like other members of this genus, exhibits gliding motility — a form of movement across solid surfaces without flagella — and typically forms flat, spreading colonies with a characteristic pigmentation on laboratory culture media. Its name may reference a type locality or the specific source environment from which it was described. As a prokaryote, this species is not evaluated under IUCN criteria, which apply to eukaryotic organisms of conservation concern. Nevertheless, soil bacterial diversity including species like C. sancti represents a vital but often overlooked dimension of biodiversity, underpinning ecosystem services upon which agriculture and natural ecosystems depend.
