Chrysococcus radians is a freshwater chrysophyte microalga in the genus Chrysococcus, class Chrysophyceae, order Chromulinales. The species epithet radians — radiating — describes a lorica with radiating spine-like projections or extensions emanating from the central body of the outer case, a morphological feature readily distinguishable under light microscopy. Radiating processes on chrysophyte loricas are thought to increase the effective surface area of the cell, potentially slowing sinking and maintaining the organism in the illuminated photic zone of freshwater lakes. C. radians has been documented from Norwegian and Swedish freshwater systems, with additional records from Denmark, consistent with a broader northern European distribution of this species. Scandinavian lakes, particularly the oligotrophic highland lakes of Norway and Sweden, harbor diverse chrysophyte communities in which Chrysococcus and related genera are frequently dominant components during spring and autumn mixing periods. The species inhabits the limnetic zone, where it engages in photosynthesis using the characteristic golden-brown chrysophyte pigments — chlorophylls a and c combined with fucoxanthin. Like other genus members, C. radians may also practice mixotrophic feeding on bacteria and dissolved organic matter, providing nutritional flexibility in oligotrophic environments. Siliceous stomatocysts produced by chrysophytes can survive in lake sediments and provide paleolimnological records of past environmental change. C. radians has not been evaluated under IUCN Red List criteria and is classified as Not Evaluated.

Péramèle Épineux

<em>Echymipera kalubu</em>, the common echymipera, is a spiny bandicoot in the order Peramelemorphia, family Peramelidae, classified as Least Concern by the IUCN Red List. Geographic range data for this species are limited; it is associated with diverse terrestrial and aquatic habitats in its distribution area, which encompasses parts of New Guinea and nearby islands in the Australasian region. Like other members of its family, <em>Echymipera kalubu</em> is a small to medium-sized marsupial with a pointed snout, compact body, and coarse, spiny fur that provides protection against predators. Bandicoots are omnivorous foragers, typically using their elongated snouts to probe soil and leaf litter for invertebrates, plant tubers, fungi, and small vertebrates. <em>Echymipera kalubu</em> is nocturnal and typically solitary, with individuals occupying home ranges in forest, scrub, and disturbed habitats. The species reproduces with a relatively short gestation period, characteristic of marsupials, with young completing development attached to teats within the mother's backward-opening pouch. Bandicoots perform important ecosystem functions as soil disturbers and seed dispersers. Biological traits of this species remain poorly documented in the scientific literature.
