Data Set Characteristics
Geographic Region: |
Geographic Description: | This study was conducted at the James San Jacinto Mountains Reserve (http://www.jamesrserve.edu), part of the University of California Natural Reserve System, located at an elevation of 1,640 m in the San Jacinto Mountains (Riverside County, California. Surrounded by the San Bernardino National Forest, the James Reserve supports 12 ha of semiarid mixed conifer and oak (Quercus sp.) forests. Here, mean annual precipitation is 507 mm, occurring primarily between November and April, and mean air temperature is 10.3°C. Derived from granitic bedrock, soils at the James Reserve are Entisols, loamy-sand textured (83% sand, 10% silt, and 7% clay), and have a bulk density of 1.2 g cm^-3.
We installed a single Ecosystem Observatory in July 2008 at ~ 40° declination in a meadow microsite (Fig. 1B), greater than 20 m from the nearest ectomycorrhizal tree where few if any ectomycorrhizal tips and fungi have been observed. Dominant vascular plants included, Artemisia dracunculus (tarragon), Eriogonum wrightii (buckwheat), Pteridium aquilinum (braken fern), and Bromus tectorum (cheat grass). Both molecular sequencing of root tips and direct identification of spores showed the AM fungi at the microsite to be Glomus spp. |

General Coverage: | In natural soils, AM fungal hyphae are morphologically and architecturally distinct; they are typically thread-like, between 4 12 μm in diameter, and dichotomously branched. We used the context (extension from the root elongation zone), architecture, and morphology to resolve them and distinguish them from fine roots and other organisms within individual images captured using the Soil Ecosystem Observatory when set at 100X magnification. |
