Coelosphaerium subarcticum is a colonial planktonic cyanobacterium in the family Merismopediaceae, as its epithet suggests, with distribution records concentrated in subarctic and boreal freshwater environments of Scandinavia, specifically Norway and Sweden. The species forms spherical mucilaginous colonies with peripheral cell arrangement typical of the genus, and its adaptation to cold water temperatures distinguishes it ecologically from congeners that prefer warmer, more eutrophic conditions. Subarctic lakes and ponds are characterised by low temperatures, ice cover for much of the year, and typically oligotrophic to mesotrophic conditions with relatively low nutrient levels. In such settings, cyanobacteria including Coelosphaerium subarcticum contribute to primary production during the ice-free summer season when available light and temperatures support photosynthesis. Gas vesicles in the cells enable buoyancy regulation, allowing colonies to rise toward surface light layers during calm conditions. Arctic and subarctic freshwater ecosystems are among the environments most sensitive to climate-driven changes, with warming temperatures extending the growing season, altering ice regimes, and potentially enabling southerly species to expand northward while cold-adapted taxa face range contraction. No formal IUCN conservation evaluation has been conducted for this species, as is typical for planktonic microorganisms at this taxonomic level.

Delfín tonina

La especie de delfín más estudiada y reconocida, los delfines mulares habitan océanos cálidos y templados de todo el mundo, desde las aguas costeras poco profundas hasta el mar abierto. Altamente inteligentes con grandes cerebros en relación con el tamaño corporal, demuestran autoreconocimiento, comunicación compleja y aprendizaje social. Viven en sociedades fluidas de fisión-fusión y cooperan para arrear peces. Una especie indicadora clave de la salud del ecosistema marino.
