The role of bracket fungi in creating alpha diversity of invertebrates in the Białowieża National Park, Poland

Bracket fungi are seen mainly as the cause of economic losses in forestry and their role as creators of biodiversity is relatively poorly understood. The effect of this group of fungi on the modification of biodiversity of invertebrates (spiders – Aranae, Opiliones – Opiliones, pseudoscorpions – Pseudoscorpionida, two groups of mites – Mesostigmata, and Oribatida, springtails – Collembola, and insects – Insecta) was investigated by analyzing 100 fruiting bodies of 10 species of bracket fungi divided into four DD classes. As well as defining the manner in which the degree of decay (DD) of the fruiting bodies determines the character of the invertebrate assemblages colonising them were the aims of this study. The material was collected at Białowieża National Park, which is considered to be the largest area of natural forests in the North European Plain. 16 068 invertebrate individuals classified into 224 species were obtained. Oribatid mites (12 543 individuals) constituted the largest gr...多孔真菌（Bracket fungi）长期以来主要被视为林业经济损失的核心诱因，但其作为生物多样性缔造者的作用却相对鲜为人知。本研究针对该类真菌对无脊椎动物群落生物多样性的调控效应展开探究，所涵盖的无脊椎动物类群包括蜘蛛目（Aranae）、盲蛛目（Opiliones）、伪蝎目（Pseudoscorpionida）、两类螨类——中气门亚目（Mesostigmata）与甲螨亚目（Oribatida）、弹尾纲（Collembola）以及昆虫纲（Insecta）。研究共分析了10种多孔真菌的100个子实体，这些子实体被划分为4个腐朽等级（Degree of Decay，简称DD）。本研究的核心目标之一，即明确子实体的腐朽等级（DD）如何决定其定殖的无脊椎动物群落的组成特征。研究样本采集于被公认为北欧平原最大天然林区的比亚沃韦扎国家公园（Białowieża National Park）。本次研究共获取隶属于224个物种的16068只无脊椎动物个体，其中甲螨（Oribatid mites）共计12543个个体，为优势类群（原文末尾内容未完整呈现）。
