Host effects on ectomycorrhizal fungal communities: insight from eight host species in mixed conifer-broadleaf forests.
To advance our understanding of host effects on the community structure of ectomycorrhizal fungi (EMF), EMF communities were compared among different host species, genera and families in two mixed conifer-broadleaf forests in Japan. Using molecular identification methods we examined EMF root tips of eight coexisting species belonging to six genera (three families): Abies and Tsuga (Pinaceae), B...
متن کاملUncommon ectomycorrhizal networks: richness and distribution of Alnus-associating ectomycorrhizal fungal communities.
The level of specificity is a key evolutionary and ecological parameter of any symbiotic interaction. Where diverse classes of mutualists interact, extracting the drivers of spatial–temporal variation in community composition is also fundamental to understanding the interaction. Ectomycorrhizal (EM) plants and fungi typically associate with many symbionts both as individuals and across a specie...
متن کاملA single ectomycorrhizal fungal species can enable a Pinus invasion.
Like all obligately ectomycorrhizal plants, pines require ectomycorrhizal fungal symbionts to complete their life cycle. Pines introduced into regions far from their native range are typically incompatible with local ectomycorrhizal fungi, and, when they invade, coinvade with fungi from their native range. While the identities and distributions of coinvasive fungal symbionts of pine invasions a...
متن کاملEvidence of species interactions within an ectomycorrhizal fungal community.
Ectomycorrhizal fungal communities can be structured by abiotic and biotic factors. Here, we present evidence for community structuring by species interactions. We sampled ectomycorrhizas and forest floor seven times during a 13-month period. The presence of various ectomycorrhizal fungal species was determined for each sample, and species co-occurrence analyses were performed. For both ectomyc...
متن کاملParasite species richness in carnivores: effects of host body mass, latitude, geographical range and population density
Aim Comparative studies have revealed strong links between ecological factors and the number of parasite species harboured by different hosts, but studies of different taxonomic host groups have produced inconsistent results. As a step towards understanding the general patterns of parasite species richness, we present results from a new comprehensive data base of over 7000 host–parasite combina...
