This episode: Trends of declining lichen populations and biocrust cover overall match trends of increasing temperatures in Colorado dryland! Download Episode (6.4 MB, 9.3 minutes) Show notes: Microbe of the episode: Cherry chlorotic rusty spot associated partitivirus Takeaways: Global climate change is affecting almost every natural system on the planet, in predictable and also sometimes unexpected, complex ways. Microbes perform key roles in many different ecosystems, providing and recycling important nutrients and even macroscopic structure. One example of this is biocrusts in dryland environments, such as areas in the western US with low annual rainfall. Microbes other organisms form a stable surface binding soil and sand particles together, helping to retain moisture and prevent erosion and transformation of land into desert. In this study of a Colorado park over more than 20 years, important species of symbiotic fungi and photosynthetic microbes in the form of lichens have declined significantly. The
