“…Another comparable finding to other studies in nontropical EcM systems was that several of the EcM genera that were more abundant in one forest type or the other correspond to documented life history strategies for these fungi as being latesuccessional (competitive) or early-successional (ruderal). The genera Lactarius and Thelephora, which were only detected in the regenerating forest, are considered earlysuccessional fungi and associated with disturbed habitats in a variety of EcM ecosystems [93][94][95][96]. Similarly, many Russula, Boletus, and Leccinum species have been found to be late-successional in some ecosystems [97,98], and we found them to be most abundant in the primary forest.…”

Human land use alters soil microbial composition and function in a variety of systems, although few comparable studies have been done in tropical forests and tropical agricultural production areas. Logging and the expansion of oil palm agriculture are two of the most significant drivers of tropical deforestation, and the latter is most prevalent in Southeast Asia. The aim of this study was to compare soil fungal communities from three sites in Malaysia that represent three of the most dominant land-use types in the Southeast Asia tropics: a primary forest, a regenerating forest that had been selectively logged 50 years previously, and a 25-year-old oil palm plantation. Soil cores were collected from three replicate plots at each site, and fungal communities were sequenced using the Illumina platform. Extracellular enzyme assays were assessed as a proxy for soil microbial function. We found that fungal communities were distinct across all sites, although fungal composition in the regenerating forest was more similar to the primary forest than either forest community was to the oil palm site. Ectomycorrhizal fungi, which are important associates of the dominant Dipterocarpaceae tree family in this region, were compositionally distinct across forests, but were nearly absent from oil palm soils. Extracellular enzyme assays indicated that the soil ecosystem in oil palm plantations experienced altered nutrient cycling dynamics, but there were few differences between regenerating and primary forest soils. Together, these results show that logging and the replacement of primary forest with oil palm plantations alter fungal community and function, although forests regenerating from logging had more similarities with primary forests in terms of fungal composition and nutrient cycling potential. Since oil palm agriculture is currently the mostly rapidly expanding equatorial crop and logging is pervasive across tropical ecosystems, these findings may have broad applicability.

SUMMARYA field study was conducted to determine the spatial distribution and temporal persistence of Laccaria bicolor (Maire) Ortori genotypes associated vvuli nafuralh tolotiizcd Norway spruce [Ficea abies (L,) Karst,] in a plantation. Groups of sporophores around three trees were mapped and collected over two to four consecutive autumn seasons to isolate cultures and determine their genetic relatedness by mating t\pe and randomly amplified polymorphic DN.^ (RAPD) analysis. Annual sporophore distribution varied significantly on all sites, with an increase in the mean radial distance from the trees over the study period. Sporophore distribution was discontinuous and characterized by clumped groupings around trees. Sporophores with the same mating type and disparate distributions were present on each of tw o sites during the sample period. RAPD analysis for each of the SIS randotn primers detected ihe same DNA polymorphisms for all dikaryolic isolates tested from a gi\ en site over the sample period. These results provide evidence that a single genetic individual of L. bicolor can remain associated with a host root system for at least 3 yr and vary significantly in its spatial distribution. This is the first instance in which the persistence of specific genotypes ol" an early-stage ectomycorrhizal fungus has been demonstrated for a tree colonized by natural sources of inoculum. The impltcations of these findings are discussed in relation to the ecology and succession of ectomycorrhizal fungi.

“…Increases in fungal species diversity are associated with ectomycorrhizal fungus succession as forest stands age and numbers of host species increase (Last et al , 1984). Fruit body production, which is the standard measure of fungal succession, is strongly influenced by seasonal changes, rainfall amount and frequency, organic content of soil, root density, and degree of ectomycorrhizal development (Wilkins and Harris, 1946;Marx et aI., 1984).…”
