Operational taxonomic units characterizing fungal communitties associated with resprouting Betula nana shrubs sampled across a fire-severity gradient in the Anaktuvuk River Fire burn scar, 2010

The dataset contains fungal community data from a sampling campaign in 2009, two growing seasons after the Anaktuvuk River Fire. We used molecular tools, including ARISA and fungal ITS sequencing, to characterize the mycorrhizal communities on resprouting Betula nana shrubs across a fire-severity gradient. Summarized data can be viewed by site and provide information on richness and abundance of basidiomycetes and ascomycetes andChao1 and MaoTau estimators of richness. OTU data are provided for each shrub sampled in the study.

本数据集收录2009年采样调查所得的真菌群落数据，该次采样距阿纳克图沃克河火灾（Anaktuvuk River Fire）已过去两个生长季。本研究采用包括ARISA（Automated Ribosomal Intergenic Spacer Analysis）与真菌内转录间隔区（Internal Transcribed Spacer，ITS）测序在内的分子生物学技术，对沿火烈度梯度分布的重新萌发矮桦（Betula nana）灌丛的菌根群落进行了表征。按样点可查阅汇总数据，其内容涵盖担子菌门（Basidiomycetes）与子囊菌门（Ascomycetes）的丰富度和丰度信息，以及群落丰富度的Chao1和MaoTau估计量。本研究中每一株被采样的矮桦灌丛均配套提供了操作分类单元（Operational Taxonomic Unit，OTU）数据。
