Species richness and composition of macroinvertebrate assemblages in the Bavarian Forest National Park: Preliminary results of the stream monitoring

Popis výsledku v původním jazyce

Ongoing monitoring of streams in the Bavarian Forest National Park (BFNP) is focused on the effects of climate changes and natural disturbances on the community composition and diversity of benthic macroinvertebrates in the Bohemian Forest. This study provides the data on macroinvertebrate assemblages of ten streams draining the area of the BFNP (BF streams), which are included in the monitoring survey, and 48 sites distributed evenly in the Große Ohe stream network (GO catchment). The GO catchment serves as a model stream network to study environmental and spatial structuring of macroinvertebrate assemblages on the local scale. We aim to evaluate species richness, abundance and species composition of macroinvertebrates along the main environmental gradients and to consider the possible impact of acidification. Species recorded at all studied sites are compared with available literature data from the BFNP. Altogether 40,682 individuals of 184 species were recorded in our study, 130 and 168 species in the BF streams and GO catchment, respectively. Macroinvertebrate assemblages of the BF streams are significantly influenced by substrate roughness and water quality. Within the GO catchment, stream size and acidity are the main ecological gradients forming the assemblages, with a significant influence of local habitat properties (such as amount of coarse particulate organic matter (CPOM), concentration of ionic aluminium (Ali), depth of water, and water chemistry). Species richness of macroinvertebrates is positively related to stream size and negatively to CPOM, whereas their abundance is significantly affected by acidity and Ali, being strongly limited in Ali>53 μg.l−1. More species of Ephemeroptera, Coleoptera and Diptera, including several acid sensitive species, were found in the GO catchment in comparison with earlier data from the period of strong acidification, which indicates ongoing recovery of streams from acidification.
