Ecological investigations on Hydrophilidae and Helophoridae (Coleoptera) specimens gathered from several water bodies of Western Turkey

摘要: The aim of this study is to present environmental variables which were effective on habitat preferences Hydrophilidae and Helophoridae species found in western region Turkey. surveys conducted Izmir, Manisa Aydin provinces specimens collected regularly during the years 2013 2014. Totally, 30 classified 8 genera two families recorded. Physicochemical parameters including temperature, dissolved oxygen, pH, electrical conductivity salinity measured from 99 different aquatic sites. relationships between effect(s) mentioned presence or absence beetles evaluated by various statistical tests. According results; conductivity, temperature are main water associated with beetle distribution. Pearson's correlation analysis coefficient was calculated as 0.965 statistically significant (p  < 0.01). determined also canonical correspondence (CCA), distributions according these presented using a CCA plot.
