A NEW APPROACH AND A MODEL STUDY IN A FLOATING ISLAND MICROBIAL BIODIVERSITY AND ENDOSYMBIONTS ON DIGESTIVE STRUCTURE OF AN AQUATIC INSECT

Globally, as wetlands are vital areas as floating islands are an important part of these wetlands in ecosystem. Due to the fact that effective results are able to obtained in terms of isolated environments, Zokun floating lake (Erzurum, Turkey) has been spatially selected as the study area. Hydrochara caraboides (Linnaeus, 1758) insect species, decreasing in number due to reasons such as climate changes, has been caught and identified by morphological methods. Firstly, morphological diagnosis of the hexapod was confirmed with respect on molecularly methods. Secondly, in laminar air flow cabinet, digestive structure of the hexapod is removed and in special sterile containers. Afterwards, microbiota of hexapod' digestive structure content has been revealed based on DNA sequences. Thirdly; heavy metals analyses a growing slice of environmental research, we surveyed the concentration of 15 heavy metals of both hexapod body and the lake water. 803 bacterial species have been identified in 207 different bacteria families. In this way, we conclude that important outcomes which very diversity of ecosystems with useful, specially endosymbiont species. It is certain that extensive research is needed to gain a positive impetus for completely acquisition of ecological data.
