Habitat & Geographic Range

Guépard

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.

Guépard

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.

Nitrosotalea devanaterra is a chemolithoautotrophic archaeon in the phylum Thaumarchaeota, notable for being the first confirmed ammonia-oxidizing archaeon that thrives under acidic conditions. It was isolated from acidic agricultural soil and plays a significant role in nitrogen cycling in low-pH environments where other nitrifying organisms cannot function. Its discovery expanded understanding of how the global nitrogen cycle operates in acidic ecosystems.
