Earthworm Diversity in Laterite and Regur Soil of Deccan Trap of Hyderabad–Karnataka Region, Karnataka, India

Earthworm Diversity in Laterite and Regur Soil of Deccan Trap of Hyderabad–Karnataka Region,... Earthworm survey was conducted across Bidar district that contains solidified lava and forms the part of Deccan trap of Hyderabad–Karnataka Region. Earthworm samples along with their habitat soil were collected by digging and hand sorting method from the selected spots like gutter, garbage, near bore well, near tap, garden, pasture, drainage system and fields. Ten different species of earthworms were identified viz., Eudrilus eugeniae of the family EUDRILIDAE; Lampito mauritii and Perionyx sansibaricus of the family MEGASCOLECIDAE; Dichogaster bolaui, D. modiglianii, Eudichogaster ashworthi, E. prashadi, E. poonensis, Octochaetona beatrix and O. paliensis of the family OCTOCHAETIDAE. Among these the genus Eudichogaster is found to be the most dominant and widely distributed earthworm in Bidar district. Eudichogaster poonensis is reported for the first time from South India. Soil chemical characteristics of their habitat were pH 6.7–8, electrical conductivity (EC) 0.28–1.16 mohs/cm, organic carbon (OC) 0.75–3.54%, nitrogen (N) 25.2–118 kg/acre, phosphorous (P) 6.6–48.8 kg/acre and potassium (K) 79–354 kg/acre. Earthworms inhabiting in the laterite soil showed wider range in the soil chemical characteristics, pH ranged from slightly acidic to alkaline; whereas earthworms inhabiting in regur soil of this region showed narrow range in the soil chemical characteristics. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Proceedings of the Zoological Society Springer Journals

Abstract

Earthworm survey was conducted across Bidar district that contains solidified lava and forms the part of Deccan trap of Hyderabad–Karnataka Region. Earthworm samples along with their habitat soil were collected by digging and hand sorting method from the selected spots like gutter, garbage, near bore well, near tap, garden, pasture, drainage system and fields. Ten different species of earthworms were identified viz., Eudrilus eugeniae of the family EUDRILIDAE; Lampito mauritii and Perionyx sansibaricus of the family MEGASCOLECIDAE; Dichogaster bolaui, D. modiglianii, Eudichogaster ashworthi, E. prashadi, E. poonensis, Octochaetona beatrix and O. paliensis of the family OCTOCHAETIDAE. Among these the genus Eudichogaster is found to be the most dominant and widely distributed earthworm in Bidar district. Eudichogaster poonensis is reported for the first time from South India. Soil chemical characteristics of their habitat were pH 6.7–8, electrical conductivity (EC) 0.28–1.16 mohs/cm, organic carbon (OC) 0.75–3.54%, nitrogen (N) 25.2–118 kg/acre, phosphorous (P) 6.6–48.8 kg/acre and potassium (K) 79–354 kg/acre. Earthworms inhabiting in the laterite soil showed wider range in the soil chemical characteristics, pH ranged from slightly acidic to alkaline; whereas earthworms inhabiting in regur soil of this region showed narrow range in the soil chemical characteristics.
