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.

Common dung beetle

<em>Aphodius pedellus</em>, a species of dung beetle in the family Scarabaeidae, is classified as Least Concern by the IUCN Red List, indicating a stable conservation outlook across its known range. The species has been documented in Denmark, Norway, Sweden, Switzerland, and the United States, with its distribution spanning virtually all terrestrial and freshwater biome types. As a member of the Aphodiini tribe, <em>Aphodius pedellus</em> typically inhabits pastures, meadows, and woodland edges where mammalian dung is available, as dung beetles in this genus rely on feces as both a breeding medium and a food resource. These beetles play a critical role in nutrient cycling and soil aeration, breaking down organic waste and accelerating the return of nutrients to the soil. Their burrowing activity beneath dung pats enhances soil structure and improves water infiltration. <em>Aphodius pedellus</em> is part of a guild of coprophagous insects that collectively support healthy agricultural and natural ecosystems across temperate Europe and North America. Biological traits of this species remain poorly documented in the scientific literature.
