Different collecting methods reveal different ecological groups of centipedes (Chilopoda)

ABSTRACT Soil invertebrates are studied by a number of methods. Here we used zoological methods (soil sampling, pitfall trapping, litter sifting, and hand collecting) to sample centipede communities in four floodplain forests (Czech Republic, Europe) and compared the efficiency of these methods. Heat-extraction from soil samples was the most effective, followed by pitfall trapping. The centipedes found by us can be divided into five ecological groups: 1) larger, abundant lithobiomorphs, 2) larger, scarcer lithobiomorphs, 3) smaller, soil lithobiomorphs, 4) abundant geophilomorphs, and 5) scarcer geophilomorphs.

摘要：土壤无脊椎动物的研究方法多样。本研究采用动物学采样方法（土壤取样法、陷阱诱捕法、凋落物过筛法与手采法），对位于欧洲捷克共和国的4处泛滥平原森林中的蜈蚣群落开展采样，并对比了各采样方法的效率。其中，土壤样本热萃取法的采样效率最高，其次为陷阱诱捕法。本次采集到的蜈蚣可划分为5个生态类群：1）体型较大且种群丰富的石蜈蚣目（Lithobiomorpha）类群；2）体型较大但种群稀少的石蜈蚣目类群；3）体型较小的土壤生石蜈蚣目类群；4）种群丰富的地蜈蚣目（Geophilomorpha）类群；5）种群稀少的地蜈蚣目类群。
