Ectomycorrhizal and wood-decay macromycete communities along development stages of managed Pinus patula stands in Southwest Mexico

摘要

This study used fruit body surveys to evaluate the diversity and distribution of ectomycorrhizal and wood-decay macromycetes along developing stages of stands artificially reforested with Pinus patula in Southern Mexico. Three stand ages were selected: 1,11, and 60 y old. Macromycetes were collected from June to October 2016 in 0.1 ha plots per stand age. A total of 106 taxa were recorded, 63 ectomycorrhizal and 43 wood-decay fungi. The highest diversity of ectomycorrhizal fungi was in 11-y stands, and 11- and 60-y stands had similar species composition. Wood-decay fungi showed a trend towards higher diversity in the 1- and 11-y stands, and species composition in these sites corresponded. Patterns of diversity and distribution were mainly determined by factors related to substratum availability and vegetation structure. Knowledge about the influence of artificially reforested stands on macrofungal communities is relevant to improve management plans and achieve a more sustainable use of forest timber and non-timber products.
