DURALL, DANIEL M.* and MELANIE D. JONES. Okanagan University College, Biology Department, 3333 College Way, Kelowna, BC, Canada, V1V 1V7. - Morphological, molecular and isotopic tracer evidence for ectomycorrhizal fungal networks linking multiple plants in the field.
The ability of ectomycorrhizal fungi to link multiple plants and to
function as a conduit for the movement of materials between plants has
been demonstrated using autoradiographic laboratory studies; however,
in the field this direct visual evidence is not available. In the
field we must rely on indirect evidence for the role of
ectomycorrhizal fungi in interplant nutrient transfer. Evidence from
morphological, molecular and tracer studies of ectomycorrhizal plants
in Douglas-fir and mixed Douglas-fir/birch forests in British Columbia
will be reviewed. These data will be compared with studies from other
systems to develop hypotheses about the presence, function and
potential influence of ectomycorrhizal fungal linkages on plant
community structure and diversity.
Key words: birch, common mycelial network, Douglas-fir, ectomycorrhiza, forestry
