Chroococcus planctonicus is a species of cyanobacteria in the family Chroococcaceae, adapted to the planktonic lifestyle suggested by its specific epithet. Unlike some Chroococcus species that are primarily benthic or periphytic — attached to substrates — Chroococcus planctonicus is characteristic of open-water plankton communities in freshwater lakes and ponds. Planktonic cyanobacteria must maintain a position in the water column for optimal light exposure, and some have evolved gas vesicles to regulate buoyancy, though these are more developed in filamentous bloom-forming genera. Chroococcus planctonicus cells are spherical, occurring in pairs or tetrads within gelatinous sheaths, following the basic morphological plan of the genus. It has been documented from European freshwater systems including Swedish and Finnish lakes, where it contributes to the seasonal phytoplankton community. Cyanobacteria are important primary producers in freshwater ecosystems, particularly in summer when warm temperatures and stratified water columns favor their growth. However, Chroococcus planctonicus is not generally associated with harmful algal blooms, which are more characteristic of genera such as Microcystis and Anabaena. Its conservation status has not been assessed.

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.
