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 Europe and South America, inhabiting ecosystems characteristic of the region.

Range

Distributed across Brazil, Norway, and Sweden.

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.

Cocconeis neothumensis is an epiphytic diatom in the family Cocconeidaceae, closely related to the type species Cocconeis thumensis but representing a morphologically and molecularly distinct taxon distinguished by the specific architecture of its silica frustule valves. The genus Cocconeis comprises adnate diatoms that attach firmly to solid substrates in aquatic environments, including the surfaces of submerged macrophytes, periphyton mats, and sediment particles in rivers, lakes, and coastal habitats. Cocconeis neothumensis has been recorded from freshwater bodies in South America and other regions, contributing to the benthic periphyton communities that coat submerged surfaces in well-lit aquatic habitats. The frustule ornamentation—including the density and arrangement of transapical striae and the morphology of the raphe system—provides the key morphological characters used to distinguish this species from its congeners under light and electron microscopy. Like all diatoms, C. neothumensis requires dissolved silicic acid to construct its frustule and depends on phosphorus and nitrogen availability for growth, making it a sensitive indicator of nutrient conditions in monitored water bodies. Periphytic diatom communities including Cocconeis species are widely used in ecological assessment frameworks such as the European Water Framework Directive to evaluate the biological quality of freshwater bodies based on assemblage composition.
