Distributed across Norway and Sweden.

Dheeb

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, deserts and xeric shrublands, and tropical and subtropical dry broadleaf forests, among 13 distinct biome types. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Africa (Seychelles), Asia (Japan), Europe (5 countries), North America (7 countries), Oceania and the Pacific (Marshall Islands, Vanuatu), and South America (5 countries). Currently classified as Critically Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.

Chroomonas mesostigmatica is a species of cryptophyte alga in the family Chroomonadaceae, described from freshwater environments. The specific epithet mesostigmatica likely refers to a centrally positioned stigma — a photoreceptive structure — within the cell, distinguishing this species morphologically from others in which the stigma is positioned differently. The stigma or eyespot in flagellate algae is associated with photoreception, enabling the cell to orient its swimming direction toward or away from light sources in a process called phototaxis. This capability is ecologically important for optimizing position in the water column relative to light availability and nutrient distribution. Chroomonas species are biflagellate, swimming with characteristic rapid, slightly helical motility. The cells contain cryptophyte-type plastids with phycobiliproteins and chlorophyll a and c. Chroomonas mesostigmatica has been documented from European freshwater habitats, contributing to the diverse microalgal communities of lakes, ponds, and slow-flowing waters. Its ecological roles include primary production and participation in the microbial loop through grazing by heterotrophic flagellates. The species has not been assessed by the IUCN.

Dheeb

The most widely distributed wild canid, gray wolves range from North America across Eurasia in diverse habitats including tundra, forests, and grasslands. Highly social animals living in family packs led by a dominant breeding pair. As keystone predators, wolves regulate prey populations and profoundly shape ecosystem structure, as demonstrated by their reintroduction in Yellowstone. Once heavily persecuted, populations are recovering in many regions.
