Diversity and habitat selection of aquatic beetles (Coleoptera).
Journal Title: IOSR Journal of Pharmacy and Biological Sciences (IOSR-JPBS) - Year 2019, Vol 14, Issue 1
Abstract
In this study the diversity and habitat selection of aquatic Coleoptera has been assessed. The order Coleoptera includes more species than any order, constitutes 25 % of known life forms. Most of the species are terrestrial but some of them are aquatic however there is doubt whether a particular species is terrestrial or aquatic that is why Jach and Bhalke (2008) classify them as true water beetles, facultative water beetles,Phytophilous water beetles etc. depending upon the time they spend in or out of the water. More than 350000 species of beetles has been described so far out of which 12000 species are known from aquatic habitat. The order has been divided into 4 suborders three of which have aquatic representatives, Myxophaga (90% aquatic), Adephaga (18% aquatic), and Polyphaga (1.25% aquatic).Polyphaga contains most families (15) of which the family Hydrophilidae represents highest number of species (2,652). Aquatic beetles areknown to have diverse habitat selection and so is their adaptability. They are found to live in almost all kinds of aquatic habitats, such as rivers, springs, lakes, ditches, puddles, phytotelmata, seepages, and ground water but did not live in oceans however they can cope with a salinity up to 250%.
