Chestnut-cheeked Starling

The Chestnut-cheeked Starling (Agropsar philippensis) is a species in the genus Agropsar. It is currently classified as Least Concern on the IUCN Red List. Typically found in various aerial, terrestrial, and aquatic environments.

Chrysococcus minutus is a small loricate chrysophyte alga in the genus Chrysococcus, its epithet minutus (Latin: minute or very small) reflecting its diminutive cell dimensions. Like its congeners, the cell is enclosed within a lorica — a rigid, often silicified or organic housing with an apical pore through which the flagellum protrudes. The lorica shape and dimensions provide taxonomic characters for species differentiation within the genus. C. minutus inhabits freshwater environments, including oligotrophic lakes, bog pools, and slow-moving waters in temperate and subarctic regions. Chrysophytes thrive in cold, acidic, low-nutrient waters and serve as reliable bioindicators of water quality. The small cell size of C. minutus places it within the nanoplankton size class, making it an important prey item for heterotrophic nanoflagellates and small ciliates in the freshwater microbial food web. Some Chrysococcus species supplement photosynthesis with bacterivorous feeding. The species has not been evaluated for conservation status and is listed as Not Evaluated by the IUCN. Loricated chrysophytes like C. minutus leave fossil siliceous cysts (stomatocysts) in lake sediments, which are widely used in paleoecological reconstructions.
