Macroinvertebrate community of a temporary Mediterranean river

Temporary rivers and streams are lotic ecosystems which are characterized by partial or complete lack of surface water in dry seasons. They have great impact on hydrology of adjacent perennial water bodies. However, until recently their importance was often overlooked, which led to degradation of these habitats. In last decades, number of studies significantly increased and an initiative for development of management procedures was launched. This research was conducted along a temporary karst river Krčić, situated beneath the Dinara Mountain. Krčić is a small river which usually dries up during summer and early autumn months. It is minimally influenced by anthropogenic activities and can thus be regarded as a reference site for temporary rivers in this region. Sampling of macroinvertebrates was performed in 2016 during the flowing phase ; in June and December, on the upper, middle and lower reaches. It encompassed all major microhabitat types (moss, fital, megalital, makrolital, mikrolital and xylal). At each site several physico-chemical parameters were measured. Community composition and structure were typical for temporary river communities, with Chironomidae as the most abundant insect group (14 taxa), followed by Plecoptera (4 taxa), Ephemeroptera (3 taxa) and Trichoptera (3 taxa). Generally, high diversity and evenness of the community were observed. The results of cluster analysis and MDS showed macroinvertebrate community separation by sampling seasons, not by macrohabitats. These results highlight the importance of seasonality in temporary rivers and streams, therefore it is necessary to perform seasonal monitoring at least twice a year.
