Cocconeis disculus is a freshwater and brackish-water diatom in the family Cocconeidaceae, belonging to the class Bacillariophyceae—the diatoms, a group of unicellular photosynthetic algae encased in ornate silica cell walls called frustules. Like all members of the genus Cocconeis, C. disculus is an adnate, epiphytic species, meaning it lives attached to substrates—typically the surfaces of aquatic macrophytes, filamentous algae, and sediment particles—rather than living freely in the water column. The frustule of Cocconeis species is distinctive in its bilateral symmetry and the characteristic difference between its two valves: the rapheless valve (RV) lacks the raphe slit present on the raphe valve (RV), a feature used in species identification. Cocconeis disculus has been documented from freshwater bodies across South America and various parts of the Northern Hemisphere, with distribution reflecting its tolerance of a range of water temperatures and nutrient conditions. Diatoms like C. disculus are foundational components of aquatic food webs, fixing carbon through photosynthesis and providing a nutritious food source for grazing invertebrates, protists, and larval fish. The species also contributes to the biosilica cycle through the production and dissolution of its silica frustule. As a benthic, substrate-attached organism, Cocconeis disculus serves as a sensitive bioindicator of water quality conditions in freshwater monitoring programs. Its conservation status is not formally evaluated.

Gelbhaarige Bergratte

The common bunomys (<em>Bunomys chrysocomus</em>) is a small rodent species found in diverse terrestrial and aquatic habitats, including tropical forests and adjacent ecosystems. This species is classified as Least Concern on the IUCN Red List, reflecting a currently stable population without immediate conservation concerns. As a member of the family Muridae, the common bunomys is an endemic rodent of Sulawesi, Indonesia, where it typically inhabits montane forest environments at moderate to high elevations. The species often forages on the forest floor, feeding on seeds, fruits, fungi, and invertebrates. Its diet and foraging behavior make it an important contributor to seed dispersal and nutrient cycling in its native forest ecosystems. The common bunomys is typically nocturnal and solitary in its habits, as is characteristic of many rodents in its genus. Biological traits of this species remain poorly documented in the scientific literature.
