A Symbiosis Between A Dark Septate Fungus, An Arbuscular Mycorrhiza, And Two Plants Native To The Sagebrush Steppe, Craig Lane Carpenter
A Symbiosis Between A Dark Septate Fungus, An Arbuscular Mycorrhiza, And Two Plants Native To The Sagebrush Steppe, Craig Lane Carpenter
Boise State University Theses and Dissertations
Plant roots form symbioses with various fungi, including arbuscular mycorrhizae (AMFs) and dark septate endophytes (DSEs). The symbiosis between plants and AMFs has been extensively studied and is generally considered to be mutualistic. Much less is known about the symbiosis between plants and DSE. In sagebrush habitats, DSEs are common, but their effects on the vegetation are unclear. As a first step to study these effects, I isolated and cultured a DSE from the roots of the shrub Artemisia tridentata. Based on partial sequences of five genes and phylogenetic analyses, the isolated fungus was a non-described species within the …
The Relative Importance Of Fire History, Management Treatments, Biotic, And Abiotic Factors On The Abundance Of Key Vegetative Components In An Endangered Sagebrush-Steppe Ecosystem, Ann Marie Raymondi
Boise State University Theses and Dissertations
Dryland ecosystems are globally distributed and occupy nearly half of Earth’s terrestrial surface. Drylands are particularly vulnerable to degradation and their restoration has become a global concern. Sagebrush-steppe ecosystems in the intermountain western United States have been subject to decades of active management efforts to address invasive species and restore plant communities, and can serve as a relevant case study to investigate dynamics between fire, invasive species, and management treatments in a representative dryland system. My objective was to determine the relative importance of fire history, management treatment history, abiotic, and biotic factors in relation to the abundance of key …
