Populations are also found in montane and highland environments at higher elevations.

Range

Found in China. 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.

Panda Gigante

El panda gigante (Ailuropoda melanoleuca) es un animal emblemático de China, célebre por su pelaje blanco y negro y su dieta basada casi exclusivamente en bambú. Su estado de conservación es vulnerable (VU), es el animal bandera de la conservación internacional de la vida silvestre, y su población ha experimentado cierta recuperación en los últimos años.

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.
