Ranunculus adoneus mycorrhizal data for Saddle 1990 - 1991.

Ranunculus adoneus plants were collected bi-weekly from Niwot Ridge Saddle grid stake 34 during the 1990 and 1991 growing seasons. Development of mycorrhizal and other fungi within plant roots was quantified. Distinct patterns of mycorrhizal development were observed and corresponded with phosporus accumulation in R. adoneus. This accumulation occurred late in the growing season after seed set, when plants were producing new tissues for the next year and appears to allow the plants to bloom the next year when snowmelt begins.
