Cinder Lichen

Cinder lichen (Aspicilia cinerea) is a crustose lichen in the family Megasporaceae, found widely across the Northern Hemisphere in boreal, montane, and arctic regions of Europe, Asia, and North America. It grows as a flat, gray to ash-gray crust on exposed siliceous rock surfaces—particularly granite, gneiss, and other hard acidic rocks—in open, high-light environments such as moorland boulders, mountain crags, stream-side rocks, and coastal outcrops. The cinder lichen's granular to warty thallus and its pale gray color, reminiscent of volcanic ash or cinder, give the species its common name. Aspicilia cinerea is classified as Least Concern, with widespread and abundant populations in suitable rocky habitats. Like many saxicolous lichens, it is extremely slow-growing and may live for centuries on stable rock surfaces. The species forms part of diverse epilithic lichen communities that colonize bare rock and contribute to biological weathering and soil formation. It is resistant to desiccation and temperature extremes, making it well adapted to exposed subalpine and arctic environments. Cinder lichen has been used as a model organism in studies of lichen growth rates and rock weathering. The genus Aspicilia is one of the largest in lichenized fungi, and molecular work has substantially revised its circumscription.

Cloud Forest Akodont

Cloud forest akodonts are small rodents in the genus Akodon (family Cricetidae, subfamily Sigmodontinae) adapted to the cool, moist cloud forests of the Andean mountain chain in South America. These small mice, typically 15–25 g body weight, are among the most diverse rodent genera in the Neotropics, with dozens of species occupying a range of habitats from tropical lowland forest to high-elevation grasslands and cloud forest margins. Cloud forest species live in mossy, fern-rich undergrowth at elevations typically between 1,500 and 3,500 meters, where they forage for seeds, fungi, invertebrates, and plant material among dense vegetation and under fallen logs. Akodonts are important prey species for forest raptors, small cats, and mustelids, and serve as seed dispersers in cloud forest ecosystems. Many cloud forest akodont species have restricted ranges tied to specific elevation bands on individual mountain ranges, making them vulnerable to climate change-driven upslope habitat shifts that compress available habitat and may eventually eliminate suitable conditions on mountains of insufficient height.
