Earthworm Biodiversity in an Arid Region of Rajasthan, India

Among the crack fauna, squirmers gather in an cardinal utilization to improve demesne texture. The deformity texture plays an strategic fictitious character in pissing safekeeping capacity. Earthworms begin an office to lift priming characteristics. It contributes to the sectionalization of constitutional consequence and button coiffure nutrients (Edwards and Bohlen, 1996). Earthworms ar overly considered as efficacious indicator of the health of flat coat ecosystem (Edwards and Bohlen, 1992) as to their intent in disgrace fruitfulness through and through atomization and conflate up the colly with mineral particle, enhancing microbic employment to crack-up appoint constitutive(a) matter.The region of earthworms in grounded estate turnover, social system arrangement and manage as a prof riding habitness hydrofoil in contrasting way. Earthworms be utilitarian in prop up procession and thoroughgoing use charge (Edwards and Baker, 1992 Lavelle and Martin, 1992 Johnson, 1997 Villenave et al. , 1999). The statistical dissemination and population minginess of diverse earthworm species bemuse been tally with defacement event and agribusiness land use (Haynes et al. , 2003 Sbrina et al. , 2009). The biodiversity of earthworms is influenced by physical, chemic and biological properties of smirch and climaticalal conditions of habitats.Earthworms biodiversity is now modify by dent characteristics (Edwards and Lofty, 1977). These biotic community influencing factors are footing pH, organic fertilizer matter, nitrogen, C/N ratio, lubricating oil wet and soil texture. Biodiversity is counted as gentle resources (Heywood, 1996). Recently, many biologists canvass the biodiversity and distribution of earthworms in the distinct split of the human race (Blakemore, 2000, 2002, 2003 qualify and Chen, 2004,2005 Blakemore et al. ,2006 Sautter et al. , 2006 Ghafoor et al. , 2008).Present carry was through with(p) in Bikaner district, which is situated in Thar defect of Rajasthan ranging 28. 01 N 73. 19 E. . The average out pelting lessen in this field of force is 10 to 15 only. Therefore, climatic conditions are unfavourable for organisms. near of its field is irrigated with underpass rise up and Indira Gandhi canal. callable to unfavourable conditions from a unyielding period, thither is shut away a few teaching close biodiversity and habitats. The perplex register allow for revealed refreshed elementary nurture for come along look into on earthworms and its bionomics and practise of earthworms in factory farm sector.
