A chronological study since 1977 in the Red Desert of Wyoming is enabling examination into the sequence of events coupling mycotrophy with revegetation following strip-mining activities. Observational data support the hypothesis that diversification in the plant community and structure is ensured with the establishment of the mycotrophic habit; thereby increasing resiliency of the community for recovery from perturbations. The objectives of this research were: (1) to identify the species of vesicular-arbuscular mycorrhizal fungi (MF) present and evaluate primary edaphic factors affecting the population dynamics of the MF; (2) to isolate native species of MF; and (3) to develop a model system for characterizing stresses such as extremes in moisture and temperature on the coupling and function (particularly the cost-benefit of mycotrophy to the host) of mycorrhizal symbionts. 2 tables.
