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, inhabiting ecosystems characteristic of the region.

Range

Distributed across 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.

Chrysochromulina throndsenii is a marine haptophyte alga named in honor of a Scandinavian researcher, reflecting the strong tradition of haptophyte taxonomy in Norwegian and Swedish phycological institutions. The species belongs to the family Prymnesiaceae and shares the characteristic features of the genus: a biflagellate cell body, a haptonema of variable length, and a surface coat of organic scales arranged in overlapping layers. Scale ultrastructure observed under electron microscopy provides the species-specific diagnostic characters essential for accurate identification within this morphologically conservative genus. C. throndsenii is documented from marine coastal waters, consistent with the broader distribution of Chrysochromulina species in temperate North Atlantic environments. As a photosynthetic nanoflagellate, it contributes to primary production and participates in the microbial loop as both a producer and potential mixotrophic consumer of bacteria. The significant role of haptophytes in the marine carbon and sulfur cycles underscores their ecological importance despite their microscopic size. The conservation status of C. throndsenii has not been evaluated by the IUCN, and the species is listed as Not Evaluated. Expanded molecular surveys will be necessary to fully understand its distribution and evolutionary relationships.
