Studies On Ecology And Breeding Behaviour of Some Selected Anurans of Odisha

Abstract

ABSTRACT newlineOut of 347 amphibian species, rhacophoridae comprises of 54 species and ranidae newlinecomprises of 90specieswhich are either aquatic, terrestrial orbelongto bothhabitat.The ranidae newlineand rhacophoridae are wetland species and found near perennial water. Inspite of close relationship newlinebetween the families, difference inecological niche and habitat isprominent. Rhacophoridae are newlinefound on trees, intree holes and inhouse. Foamnestof rhacophoridae is adhered to twigs above newlinethewater level. Both groups are seasonal breeders. Ranidae are found in permanent ponds rich newlinewith hydrophytes or thick vegetation nearby. If we study the nature, Polypedates maculatus is newlinearboreal and frequently encountered near the habitation of human.Amplecting pairs of ranidae newlinemove and layeggs inscattered mannerwhich adhered to aquatic plant. Present study provides a newlinecomparative assessment of behaviour likeecological and breedingstrategyof two anuranspecies newlineof ranidae (Euphlyctis hexadactylus) and rhacophoridae (Polypedates maculatus) in North newlineOdisha andNorthWest Odisha. newlineObjectives and Tasks Carried out: newlineThe objectives of the proposed investigation were to study the following: newline1. Habit and habitat of E. hexadactylus and P. maculatus in North Odisha and North newlineWest Odisha.(Inter district variation) newline2. Body size, sexratio, sizeat first maturityand clutchsizeof both species. (Differences in newlinelocalities with respect to two different families) newline3. Overviewof breeding strategy, development and tadpole characterization of these newlinespecies sampled during the studyperiods. newlinexi newlineTools used and Methodology (In Brief): newlineField studyand sampling of Indian green frogEuphlyctis hexadactylus and Indian tree newlinefrog Polypedates maculatuswere conducted during February 2018-June 2021 from different newlinelocalities of North Odisha and NorthWest Odisha. Sampling areas are in the near byareas of newlineMayurbhanjDistrict (Mrugabadi, Bankati)ofNorthOdisha and are inthevillage of Pradhanpat newlineand Barakot of Deogarh district of North West Odisha.
