本研究在阿肯色州西北部奥扎克山脉的三个地点进行，调查了规定的燃烧对木材分解真菌的影响，使用腐烂的木质残体（DWD）放置在塑料孵化室的样品。其中一个地点最近没有进行规定的焚烧，而其他地点既有未焚烧的地区，也有最近进行过焚烧的地区。在所有三个地方，小块腐烂的木质残体（DWD）收集，放置在孵化室和后者保持潮湿的任何延长的时间。在焚烧区收集的DWD碎片通常显示出大量炭化的迹象。取出培养室中出现的子实体，并通过核糖体DNA区域测序进行鉴定。在整个调查中，共记录了101个标本，代表80个不同的分类群，但标本和分类群的数量都明显高于未燃烧的收集地点。因此，获得的数据表明，规定的燃烧降低了与DWD在特定地点的木材分解真菌的物种丰富度。本研究的独特之处在于使用培养箱来表征与CWD相关的真菌类群。
The present study, which was carried out at three localities in the Ozark Mountains of northwest Arkansas, investigated the effects of prescribed burning on wood-decomposing fungi using samples of decaying woody debris (DWD) placed in plastic incubation chambers. One of the localities had not been subjected to recent prescribed burning, whereas the other localities contained both an unburned area as well as an area recently subjected to burning. In all three localities, small pieces of decaying woody debris (DWD) were collected, placed in the incubation chambers and the latter kept moist for any extended period of time. Pieces of DWD collected in the areas subjected to burning typically displayed evidence of considerable charring. Fruiting bodies appearing in the incubation chambers were removed and identified by sequencing of ribosomal DNA region. A total of 101 specimens representing 80 different taxa were recorded in the entire investigation, but the numbers of both specimens and taxa were appreciably higher for the unburned collecting sites. As such, the data obtained indicate that prescribed burning lowers the species richness of the wood-decomposing fungi associated with DWD at a particular locality. The unique aspect of the present study was the use of incubation chambers to characterize the taxa of fungi associated with CWD.
