Bavarian Pine Vole

The Bavarian Pine Vole (Microtus bavaricus) is a species in the genus Microtus. It is currently classified as Critically Endangered on the IUCN Red List. Typically found in diverse terrestrial and aquatic ecosystems.

Chrysosphaerella brevispina is a colonial chrysophyte alga in the genus Chrysosphaerella, class Chrysophyceae. The genus is defined by its colonial organization: cells are arranged in spherical or discoid colonies in which each cell bears siliceous scales on its surface and projects stiff, spine-like silica bristles outward. The specific epithet brevispina (Latin: short spine) describes the relatively short silica spines that distinguish this species from congeners bearing longer projections. C. brevispina is found in freshwater environments, particularly in oligotrophic lakes and ponds of Scandinavia, where chrysophyte communities are richest. Chrysosphaerella species, like other chrysophytes, thrive in cold, clear, soft-water habitats and are sensitive indicators of water quality. The silica spines and scales produced by Chrysosphaerella cells are preserved in lake sediments as microfossils, providing paleoenvironmental records stretching back thousands of years. The spines may function as anti-grazing structures, reducing ingestion by zooplankton. The species has not been evaluated for conservation status by the IUCN and is listed as Not Evaluated. Its ecology and distribution in lakes outside Scandinavia are incompletely documented.
