Chubby Grimmia

The Chubby Grimmia (Schistidium flaccidum) is a small acrocarpous moss in the family Grimmiaceae, found on acidic rock surfaces across northern Europe and Scandinavia. Despite its common name, the species belongs to the genus Schistidium rather than Grimmia, although the two genera are closely related within the family. S. flaccidum grows in compact cushion-forming tufts on siliceous boulders, cliff faces, and rocky outcrops in humid, often montane environments. The moss is documented from Norway and Sweden, where it occurs in habitats typical of boreal and subarctic rock communities. Like other Schistidium species, it produces sporophytes with exserted or immersed capsules that release spores for dispersal. The genus Schistidium is one of the largest among saxicolous (rock-dwelling) mosses, with many species distinguished by subtle differences in leaf shape, costa characteristics, and peristome structure. C. flaccidum has not been evaluated for conservation status by the IUCN and is listed as Not Evaluated. Rocky habitats support diverse bryophyte communities that are sensitive to air quality and moisture regimes. The ecology of Schistidium species on Scandinavian rock communities has been the subject of detailed phytosociological studies.

Cochabamba Akodont

The Cochabamba akodont (Akodon siberiae) is a small South American rodent endemic to the Cochabamba department of Bolivia. A member of the speciose genus Akodon — the so-called grass mice — this species inhabits humid montane grasslands and shrublands in the Andes, typically at elevations between 2,500 and 3,800 metres. Like other akodont rodents, it is primarily granivorous and insectivorous, foraging among dense grass tussocks and low vegetation for seeds, invertebrates, and plant material. The species is fossorial to a degree, constructing runways and shallow burrows beneath grass cover that provide shelter from predators including raptors and small carnivores. Akodon siberiae was described relatively recently from specimens collected in the Cochabamba region and remains poorly known; much of its ecology and reproductive biology has been inferred from better-studied congeners. Population size estimates are unavailable, though the IUCN classifies it as Near Threatened due to its restricted range and ongoing habitat conversion driven by agricultural expansion, livestock grazing, and burning of Andean grasslands. The species may have some tolerance for modified habitats but its dependence on intact puna and montane scrub makes it vulnerable to continued land-use change. Conservation measures such as protection of remnant native grassland within its limited range are considered important for its long-term persistence.
