Soil organic carbon directly influences the life-supporting services provided by soils, including the production of food and the regulation of atmospheric carbon dioxide. To better understand how minerals such as calcium affect carbon accumulation in soil, researchers studied soils collected from Point Reyes National Seashore. Read more »
In Fruit-Fly Gut, Bacterial Niche Gets Remodeled for New Arrivals
Researchers found that fruit flies have a specialized niche in their digestive tracts that selects, maintains, and controls bacteria that benefit the fly. Colonization by one type of bacteria physically remodels the niche, promoting secondary colonization by unrelated bacteria. The results will help dissect the mechanisms of host-microbe symbiosis.
