| Summary: | Previous studies which investigated macroinvertebrate colonization of submerged wooden substrates in streams and lakes did not consider the wood species. In this study, the genus of randomly collected twigs and branches from two streams was determined microscopically using morphological and structural characteristics of the wood genera. The macroinvertebrate colonization of the wooden substrates was analysed with respect to the different kinds of the twigs and branches. Additionally, an exposition experiment was conducted with the most commonly found wood genera, alder (Alnus) and oak (Quercus), in two different states of decay (freshwood and conditioned wood). The colonization experiment stressed the results of the natural wood samplings that the wood genus plays only a minor role in the colonization by macroinvertebrates. |
