Arbuscular Mycorrhizal Fungi and Alien Plant Species
The invasion success of alien plant species depends, amongst other things, on their functional traits [4] and the susceptibility of ecosystems. There is now increasing interest in including biotic interactions particularly mutualistic associations [5], into frameworks assessing alien plant invasions, as they help bridge the invisibility and invasiveness features. The great majority of terrestri...
متن کاملArbuscular mycorrhizal fungi respond to increasing plant diversity
The effect of plant diversity (1, 2, 8, or 16 species) on arbuscular mycorrhizal fungi (AMF) was assessed at the Cedar Creek Long-Term Ecological Research site at East Bethel, Minnesota, from 1997 to 1999. At each of the five samplings, AMF in 16-species plots produced from 30 to 150% more spores and from 40 to 70% greater spore volumes than AMF in one-species plots. Regressions of spore number...
متن کاملPlant coexistence mediated by arbuscular mycorrhizal fungi
Recent research has indicated the importance of arbuscular mycorrhizal fungi (AMF) in mediating plant coexistence. Coarse-scale studies compare the effects of the presence versus absence of AMF on plant coexistence, a phenomenon that is most relevant in early successional ecosystems where AMF are patchily distributed. By contrast, fine-scale studies investigate interactions that might occur onc...
متن کاملPlant and soil response to single and mixed species of arbuscular mycorrhizal fungi under fungicide stress
Defining sustainable agricultural practices requires an understanding of both aboveand below-ground consequences to management strategies. While alternatives to biocides are sought for the control of weeds, insects and pathogens, biocide use will continue with the goal of reducing quantities used in an integrated approach. The impact of three fungicides on plant growth, seed yield, seed nutrien...
متن کاملSpecies of plants and associated arbuscular mycorrhizal fungi mediate mycorrhizal responses to CO2 enrichment
It has been suggested that enrichment of atmospheric CO2 should alter mycorrhizal function by simultaneously increasing nutrient-uptake benefits and decreasing net C costs for host plants. However, this hypothesis has not been sufficiently tested. We conducted three experiments to examine the impacts of CO2 enrichment on the function of different combinations of plants and arbuscular mycorrhiza...
