Chinese Jumping Mouse

The Chinese Jumping Mouse (Eozapus setchuanus) is a species in the genus Eozapus. It is currently classified as Least Concern on the IUCN Red List.

Chrysococcus punctiformis is a unicellular freshwater chrysophyte microalga in the genus Chrysococcus, class Chrysophyceae. The specific epithet punctiformis — meaning point-shaped or dot-like — likely references the diminutive size of this species relative to other Chrysococcus species, or alternatively describes a distinctive punctate surface pattern on the lorica visible under microscopy. In Chrysococcus, the lorica is the primary taxonomic structure, and its form, texture, and any ornamentation distinguish species from one another. C. punctiformis has been recorded from Norwegian and Swedish freshwater environments, extending also to Brazilian localities. This broad distribution spanning subarctic Scandinavian lakes and tropical or subtropical South American water bodies suggests either genuine cosmopolitan dispersal of this species through passive mechanisms, or convergent morphological evolution that has been misidentified as the same taxon in different regions. Molecular phylogenetic data would help resolve this question. The species inhabits the limnetic zone of freshwater systems, where it functions as a primary producer and component of the nanoplankton community. Chrysococcus species are characteristic members of oligotrophic lake phytoplankton in Scandinavia, often co-occurring with other chrysophytes, diatoms, and chlorophytes. C. punctiformis uses chlorophylls a and c along with fucoxanthin for photosynthesis and may practice mixotrophic nutrition. It has not been assessed under IUCN criteria and is listed as Not Evaluated.
