Habitat & Geographic Range

Éléphant de savane

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 5 distinct biome types within the Afrotropic biogeographic realm. Populations are also found in montane and highland environments at higher elevations.

Range

Found in Kenya. Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Coccolithophorid

Habitat

Native to Europe and North America, inhabiting ecosystems characteristic of the region.

Range

Distributed across Norway, Sweden, and United States.

Éléphant de savane

The largest land animal on Earth, African elephants can reach 7,000 kg and inhabit sub-Saharan savannas, forests, and wetlands. Highly intelligent with complex social structures led by matriarchs, they communicate through infrasound, rumbles, and touch. As ecosystem engineers, they shape habitats by uprooting trees, digging waterholes, and dispersing seeds. Vulnerable, with populations declining due to ivory poaching and habitat loss.

Coccolithophorid

Hymenomonas roseola is a marine coccolithophore in the class Prymnesiophyceae, belonging to the order Coccolithales—a group of single-celled phytoplankton celebrated for covering their cell surfaces with ornate calcium carbonate scales known as coccoliths. This species is notable for producing distinctive coccoliths with a characteristic architecture visible under electron microscopy. Like all coccolithophores, Hymenomonas roseola plays a significant role in oceanic biogeochemical cycles: the formation of calcium carbonate coccoliths drives the biological carbon pump by fixing inorganic carbon into mineral form, which sinks upon cell death to accumulate in deep-sea sediments. The species inhabits the photic zone of temperate to subtropical marine waters in the North Atlantic, Mediterranean, and Pacific regions, where it has been documented from coastal and open-ocean samples. As a photosynthetic organism, it requires sunlight for carbon fixation and typically blooms in stratified surface waters with adequate nutrients. Coccolithophore blooms can be so dense as to be visible from space as turquoise patches in satellite imagery. Hymenomonas species have also been noted for their ability to calcify in culture, making them useful laboratory models for studying coccolith biomineralization mechanisms and the potential impacts of ocean acidification, which threatens to dissolve calcium carbonate structures as seawater pH decreases. Its conservation status has not been formally evaluated.
