“…Diversity (S and H) and community structure of chironomid communities in the studied salt marshes showed fluctuations related to the season. Seasonal variations in the structure of chironomid communities have often been observed (Milošević et al, 2013; Tóth et al, 2013; Głowacki et al, 2023), which is not surprising given that many environmental factors show cyclic variation during a year. The lowest diversity at the majority of study sites was recorded in winter.…”

Continental salt marshes represent specific inland saltwater bodies with unique ecological characteristics a fact that is mirrored by specific flora and fauna. However, there is still limited data on their biota in Serbia, which is especially true for aquatic macroinvertebrates, including chironomids (Diptera: Chironomidae). Here we investigated diversity and seasonal variations of chironomid community in six salt marshes distributed in the northern and southern part of Serbia. We recorded a total of 25 species, of which two are new for the Serbian chironomid fauna. Most of the recorded species are common in freshwaters and several of them are halotolerant. Chironomid community structure fluctuated in relation to the seasons. The highest diversity was recorded in the spring and summer months for the majority of studied salt marshes. The present findings should contribute to the knowledge of the faunistic composition of salt marshes in Serbia and provide a basis for future distributional and ecological studies of chironomids.

The family Chironomidae is speciose and is present in almost all freshwater habitats. Adult non-biting midges emerge from waterbodies and swarm in high numbers, occasionally disrupting people’s outdoor activities. In order to understand the seasonal dynamics of species composition, a continuous observation of non-biting midge diversity was performed. Adult non-biting midges were collected using light traps from the autumn of 2022 to the summer of 2023 in an urban wetland park. Species were identified based on morphological characteristics and DNA barcodes. Alpha diversity was evaluated using Margalef, Pielou, and Shannon–Wiener indexes. Beta diversity was evaluated using unconstrained NMDS analysis and constrained CCA. The impacts of environmental factors, including barometric pressure, temperature, relative humidity, and wind speed, on the variation in species composition were estimated in the constrained analyses. A total of 42 species were identified, with 29 species belonging to Chironominae, 9 species belonging to Orthocladiinae, and 4 species belonging to Tanypodinae. The species composition varied across different seasons. Summer sites and autumn sites shared the highest similarity in diversity, and spring sites presented the lowest diversity. The variation was significantly correlated with environmental conditions. The results showed that seasonality is a factor influencing the diversity of adult non-biting midges.

Chironomidae, commonly known as non-biting midges, are key indicators of the health and biodiversity of freshwater ecosystems. They are also one of the most abundant and diverse groups of aquatic invertebrates. Although Chironomidae are ecologically important, abundant and diverse, there has been limited focused research on this group in Lithuania. Our study addresses this gap by analysing the diversity of Chironomidae in six Lithuanian streams. In this study, we present a comprehensive list of Chironomidae collected from six streams with similar hydrological characteristics: three dammed and three undammed. Lithuania is home to 158 species of known species of Chironomidae, comprised of 22 species in the subfamily Tanypodinae, 87 in the Chironominae, 42 in the Orthocladiinae, four in the Diamesinae and three in the Prodiamesinae. Throughout our research, we collected 11,296 chironomid specimens using a D-shaped aquatic net. Amongst these specimens, we identified 89 species representing 65 genera and five subfamilies, including 37 species and 12 genera, were recorded for the first time in Lithuania. The subfamily Chironominae, with 28 genera and 6,816 specimens, has exhibited the highest abundance of non-biting midges both in terms of genera and individuals. Amongst the streams investigated, the Luknelė was the richest in diversity, harbouring 37 genera and 2,657 individuals, accounting for about 55% of the Chironomidae genera found during the research. Our findings significantly enhance the understanding of the Lithuanian Chironomidae fauna, marking the first comprehensive study of such a kind, as previous knowledge of this fauna has been derived only from related studies.
