Release of potassium from rock powder by the yeast Torulaspora globosa
Brazilian Archives of Biology and Technology, 2012 The alteration of minerals in rocks and the availability of elements for plant nutrition require long periods of time, and microorganisms are thought to induce the release of potassium and phosphate from rocks.

Extreme environments in a world of new extremes
Ecosphere, Volume 17, Issue 2, February 2026.Abstract Extreme environments, whether defined by climate, soils, or disturbance, at landscape or micro‐scales, are prevalent across Earth's surface and have long served as crucibles for ecological and evolutionary insights. Many foundational theories were developed in deserts, cliffs, ultramafic soils, and other harsh systems.
