Alpine Field Mouse

The Alpine Field Mouse (Apodemus alpicola) is a species in the genus Apodemus. It is currently classified as Least Concern on the IUCN Red List. Typically found in diverse terrestrial and aquatic ecosystems.

Colacium simplex is a photosynthetic euglenoid protist in the family Euglenaceae, notable for its epibiotic lifestyle as a stalked organism colonizing the surfaces of freshwater crustaceans and other zooplankton. This microscopic species belongs to a genus that bridges free-swimming euglenoid behavior and sessile, colonial existence, attaching to hosts via mucilaginous stalks. Colacium simplex, as its name implies, exhibits a relatively uncomplicated morphology compared to other genus members, with simple colony structures that anchor to copepods, cladocerans, and occasionally other small invertebrates. The organism photosynthesizes when light is available, using chloroplasts derived from the green algal endosymbiont common to euglenoids, while potentially employing osmotrophic nutrition in darker conditions. Its presence on zooplankton hosts can affect host swimming behavior and, in heavy infestations, may impose a metabolic cost on the carrier. Colacium simplex inhabits lentic and slow-moving lotic freshwater systems globally, wherever appropriate zooplankton hosts occur. It plays a role in microbial community structure and organic matter dynamics in planktonic food webs. Taxonomic understanding of the genus continues to evolve with molecular phylogenetic studies.
