Broken-barred Roller

The Broken-Barred Roller (Ancylis unguicella) is a species in the genus Ancylis. It is currently classified as Least Concern on the IUCN Red List. Typically found in virtually all terrestrial and freshwater habitats.

Chrysococcus triporus is a unicellular freshwater chrysophyte microalga in the genus Chrysococcus, class Chrysophyceae. The species epithet triporus — three-pored — refers to the presence of three distinct pores in the lorica, the outer proteinaceous or polysaccharide envelope that encloses the Chrysococcus cell. Pore number and arrangement provide useful taxonomic characters in this genus, alongside lorica shape, surface texture, and the presence or absence of additional projections or ornamentation. C. triporus has been recorded from Norwegian and Swedish freshwater environments, fitting the established pattern of chrysophyte diversity in Scandinavian lakes and ponds. Records from Brazil suggest a broader distribution, though it is uncertain whether Scandinavian and South American populations represent a single species or cryptic lineages that require molecular resolution. The species inhabits the limnetic zone of freshwater bodies, contributing to primary production through photosynthesis with chlorophylls a and c and fucoxanthin pigments. The cell body is enclosed within the lorica from which one or two flagella emerge through a specialized opening, enabling active swimming in the water column. Chrysococcus species function as prey for ciliates, flagellates, and zooplankton, linking primary production to higher trophic levels in freshwater food webs. C. triporus may also produce siliceous stomatocysts as resting stages that can persist in sediments. The species has not been formally evaluated under IUCN criteria and retains a conservation status of Not Evaluated.
