Chrysococcus granulatus is a unicellular freshwater chrysophyte microalga in the genus Chrysococcus, class Chrysophyceae. The species epithet granulatus — granular or granulated — describes a textured surface on the lorica of this species, a feature visible under electron microscopy that contrasts with the smooth surfaces of some congeners. In the genus Chrysococcus, the lorica is a secreted outer covering enclosing the cell, and its surface texture, shape, and any projections or pores form the primary morphological characters distinguishing species from one another. C. granulatus has been documented from Norwegian and Swedish freshwater bodies, consistent with the strong Scandinavian research tradition in chrysophyte taxonomy. Scandinavian oligotrophic and mesotrophic lakes are important reservoirs of chrysophyte diversity, harboring numerous species of Chrysococcus, Chromulina, Ochromonas, and related genera. Records from Brazil and Denmark extend the known distribution of C. granulatus, suggesting cosmopolitan or at least widespread dispersal capability through passive transport mechanisms such as wind, waterfowl, and hydrological connectivity. The species is a golden-brown phytoplankton organism with chlorophylls a and c and fucoxanthin carotenoids, enabling photosynthesis in the limnetic zone. Like other Chrysococcus species, C. granulatus may supplement photosynthesis with phagotrophic uptake of bacteria. It has not been assessed under IUCN criteria and carries a conservation status of Not Evaluated. The species contributes to understanding freshwater chrysophyte taxonomy and biodiversity in Scandinavian aquatic ecosystems.

Colorful Pericote

<em>Auliscomys pictus</em>, the colorful pericote, is a rodent in the family Cricetidae within the diverse South American assemblage of sigmodontine mice. This species is assessed as Least Concern by the IUCN and is associated with diverse terrestrial and aquatic ecosystems. Pericotes of the genus <em>Auliscomys</em> are typically inhabitants of high-altitude Andean environments, including puna grasslands, rocky slopes, and shrublands above the treeline. The colourful pelage suggested by the common name may reflect variation between the dorsal and ventral fur colouration typical of many Andean small mammals, providing countershading against open sky and substrate backgrounds. Like other small Andean rodents, <em>Auliscomys pictus</em> is likely omnivorous to herbivorous in diet, consuming seeds, plant material, and occasionally invertebrates. These rodents serve as important prey items for Andean raptors, foxes, and mustelids, occupying a central trophic position in high-altitude ecosystems. Limited survey data from specific countries have been recorded for this species. Biological traits of this species remain poorly documented in the scientific literature.
