Short Communication: Distribution of dragonflies (Odonata: Insecta) in South Ural lakes, Russia

Abstract

Mashkova IV, Krupnova TG, Kostryukova AM, Vlasov NE. 2018. Short Communication: Distribution of dragonflies (Odonata: Insecta) in South Ural lakes, Russia. Biodiversitas 19: 202-207. This paper studies the diversity and distribution of Odonata (Insecta) in the South Urals region lakes such as Lake Large Miassovo, Lake Small Miassovo, Lake Ilmenskoe, Lake Savelkul and Lake Baraus. We revised dragonflies in five lakes during May-September 2014-2016. Dragonflies and larvae were identified up to the species. As results, 36 species (12 Zygoptera and 22 Anisoptera) belonging to 15 genera were recorded. To compare the similarities of dragonfly communities of different lakes we used the Canonical Correspondence Analysis (CCA) according the Jaccard index. Comparing the number of records of odonate species for selected lakes in our study, we found that the small richness of species was typical for lakes Savelkul and Baraus (22% and 25% of the total number of species, respectively) and the large values of the species richness was obtained for lakes Small Miassovo, Ilmenskoe and Large Miassovo (50%, 72%% and 80% of the total number of species, respectively).

DIVERSITY OF Odonata AND AQUATIC ENVIRONMENTAL CONDITIONS IN LAKE AREA (WATER SKI AND OPI) JAKABARING PALEMBANG-SOUTH SUMATERA

“…Whereas location B (OPI Lake) (0.6989)> 0.5, there are still species that dominate, namely Brachythemis contaminata and Orthetrum sabina species. Brachythemis contaminata species have the highest number of individuals in location B, it is suspected that this species has a high and frequent or commonly found life ability [17], [25], and Brachythemis contaminata species are species that can reflect unfavorable environmental conditions (tabel1) [26].…”

“…The location B (OPI) evenness index <0.5 this is due to the number of individuals species dominating the Brachythemis contaminata and Orthetrum sabina species so that the number of individuals of each other species is not the same or uneven. Brachythemis contaminata has a high tolerance of life ability [26], while Orthetrum sabina has the ability to fly, commonly found every year, and has a high tolerance and wide distribution [28] [17], although the amount is not as much as Brachythemis contaminata [14]. The higher the evenness value, the higher the diversity of species, and the stability of the ecosystem in the environment [29].…”

“…Odonata not only designs habitats, but also environment related to air bodies [16]. In addition according to the [17], the Odonata has a good adaptation rate, abundant in aquatic environments as well as high morphological specialization that distinguishes it from other winged insects. Therefore, the Odonata Study on the lake (Water Ski and OPI) of the Jakabaring-Palembang region in the swampland area is an indicator of conservation conditions.…”
