Short-term effects of seasonal prescribed burning on the ectomycorrhizal fungal community and fine root biomass in ponderosa pine stands in the Blue Mountains of Oregon

Canadian Journal of Forest Research (2004)

Jane E. Smith Donaraye McKay C.G. Niwa Walter G. Thies Greg Brenner

The effects of seasonal prescribed fire on the belowground ectomycorrhizal community and live fine root biomass were investigated before, 1 year after, and 2 years after prescribed underburning. Ectomycorrhizas were sampled from four replications of three treatments (fall underburning, spring underburning, and a nonburned control) in a randomized complete block design. Samples were separated in two subsamples representing the upper 5 cm and lower 5 cm of a soil core. Molecular tools were used to distinguish 140 restriction fragment length polymorphism (RFLP) species of fungi directly from the ectomycorrhizas. Prior to underburning, the number of RFLP species and amount of live root biomass were similar among treatment units and between upper and lower core samples. Fall underburning largely removed live root biomass to a depth of 10 cm and significantly reduced ectomycorrhizal species richness compared with spring underburning and the nonburned control for at least 2 years. RFLP species richness and live root biomass following spring underburning were generally similar to the nonburned treatment. The successful reintroduction of fire to the ecosystem to retain high species diversity of ectomycorrhizal fungi and achieve the desired future condition of large-tree ponderosa pine retention with low fuel loads may require more than underburning in a single season.

Biology of the ectomycorrhizal genus, Rhizopogon

New Phytologist (1997)

Randy Molina Jane E. Smith Donaraye McKay Lewis Melville

summary Seedlings of Pseudotsuga menziesii (Mirb.) Franco, Pinus ponderosa Dougl. ex Laws, Arbutus menziesii Pursh., and cuttings of Arclast apliylos uva‐ursi (L.) Spreng were grown in monoculture and in conifer‐hardwood dual‐culture combinations in the glasshouse and inoculated with spore slurries of six Rhizopogon species. The primary objectives were to assess and compare the pattern of host specificity between symbionts and to study the influence of co‐cultured plants on ecromycorrhiza development. The Rhizopogon spp. ranged from genus‐specific to multiple‐host compatible. In monoculture, four Rhisopogon sp, ( R. ellenae Smith, R. occidentalis Zeller & Dodge, R. smithii Hosfnrd and R. subcaerulescens Smith) formed ectomycorrhizas with Pinus ponderosa , and two Rhizopogon sp. ( R. parksii Smith and R. vinicolor Smith) formed ectomycorrhizas with Pseudotsuga menziesii . None of the fungi tested developed ectomycorrhizas on Arbutus menziesii or Arctostaphylos uvaursi in monoculture. In dual culture, three of the four Rhizopogon species ( R. ellenae, R. occidentalis and R. subcaerulescens) that formed ectomycorrhizas on Pinus ponderosa , formed some ectomycorrhizas on Arbutus menziesii and Arrtastaphvlos uva‐ursi. Rhizopogon parksii and R. tinicoior only formed ectomycorrhizas on Pseudotsuga mensiesti.

Survival of mycorrhizal fungal isolates stored in sterile water at two temperatures and retrieved on solid and liquid nutrient media

Canadian Journal of Microbiology (1994)

Jane E. Smith Donaraye McKay Randy Molina

Vegetatively colonized agar cores of 169 reputed mycorrhizal fungal isolates, representing 18 Ascomycotina, 141 Basidiomycotina, and 10 Deuteromycotina fungi, were stored at 4 and 18 °C in tubes of sterile deionized water. Viability, based on growth on solid and liquid nutrient media at 18 °C, was determined after a 20-month storage period. Ninety-five percent of the isolates were retrieved in at least one of three treatments: 89% in liquid nutrient media and 84% on solid media after storage at 18 °C, and 78% on solid media after storage at 4 °C. Nearly all Ascomycotina and Deuteromycotina isolates were retrieved regardless of the storage temperature or form of retrieval medium. Basidiomycotina isolates differed more in survival and percentage of viability than Ascomycotina or Deuteromycotina. For example, storage temperature influenced the viability of Laccaria isolates and the form of retrieval medium influenced the viability of Rhizopogon isolates.Key words: culture maintenance, fungal storage, long-term storage, mycorrhizal fungal isolates, water storage.

Early impacts of forest restoration treatments on the ectomycorrhizal fungal community and fine root biomass in a mixed conifer forest

Journal of Applied Ecology (2005)

Jane E. Smith Donaraye McKay Greg Brenner JIM McIVER Joseph W. Spatafora

Summary The obligate symbiosis formed between ectomycorrhizal fungi (EMF) and roots of tree species in the Pinaceae influences nutrient uptake and surrounding soil structure. Understanding how EMF respond to prescribed fire and thinning will assist forest managers in selecting fuel‐reducing restoration treatments that maintain critical soil processes and site productivity. The response of EMF species richness, live fine root biomass and duff levels to various forms and combinations of thinning and burning was investigated in mixed ponderosa pine and Douglas fir stands in the Blue Mountains of Oregon. The below‐ground community composition and structure of EMF at the site was characterized using molecular methods. The EMF community consisted of a large number of infrequently detected species. The distribution of a few abundant species ( Cenococcum sp., Piloderma sp., Rhizopogon salebrosus and Wilcoxina rehmii ) in a majority of the treatments both before and after treatment application demonstrates that some EMF species survive or rapidly re‐establish after disturbance. EMF species richness, live root biomass and duff levels were reduced significantly by prescribed fire treatments compared to the non‐burned treatments. Synthesis and applications. These results indicate that prescribed fire results in a short‐term reduction in EMF species richness and live root biomass and may influence whether managers can achieve the desired future condition of stands with large‐tree retention and low fuel loads. EMF mortality and complete duff reduction after fire have been implicated with poor tree survival and slow stand recovery in forest ecosystems world‐wide. The results of this study, along with the recovery potential of a site, and the impending risk of stand‐replacing wildfire in stands differing in structure from historic conditions, bear consideration when reintroducing fire.
