Abstract

In this study diversity, abundance and functional feeding guild of aquatic entomofauna were assigned within submerged macrophyte stands in Jankovac Stream reservoirs (Papuk Nature Park). The main aims of this study were to analyse: (i) physico-chemical parameters and food resources; (ii) abundance and diversity and (iii) functional feeding guilds of entomofauna. Between reservoirs non significant differences were observed in regard to abiotic or biotic parameters, except higher abundance of active fi lterers in vegetated littoral zone of Reservoir 1 (R1M) than in Reservoir 2 (R2M). Other parameters mostly showed significant seasonal oscillations. In total 19 taxa
were identified, among them 14 in R1M, and half less in R2M. Highest
abundance was reached in R1M in winter (544 ind m-2), and in R2M in spring (472 ind m-2). Ephemeroptera (R1M 66 %, R2M 76 %) with domination of Cloeon sp., and Diptera (23 % in R1M and R2M) with dominated Tanitarsini specimens contributed at most in total abundance. Among feeding guilds the greatest contribution in abundance achieved detritivores (81 %). Results of this study suggested that food resources and biotic interactions are main drivers in structuring entomofauna, i.e., macroinvertebrate community in submerged macrophyte stands.
