Earthworm Biodiversity in an Arid Region of Rajasthan, India

Among the dirt fauna, night crawlers have a significant job to improve soil surface. The dirt surface assumes a significant job in water holding limit. Worms have a capacity to upgrade soil qualities. It adds to the breakdown of natural issue and discharge plant supplements (Edwards and Bohlen, 1996). Night crawlers are additionally considered as valuable marker of the strength of soil biological system (Edwards and Bohlen, 1992) concerning their job in soil ripeness through fracture and stirred up the dirt with mineral molecule, upgrading microbial movement to breakdown plant natural matter.The commitment of worms in soil turnover, structure development and fill in as a richness enhancer in various way. Worms are valuable in land improvement and natural waste administration (Edwards and Baker, 1992; Lavelle and Martin, 1992; Johnson, 1997; Villenave et al. , 1999). The conveyance and populace thickness of different worm species have been associated with soil type and farming area us e (Haynes et al. , 2003; Sbrina et al. , 2009). The biodiversity of night crawlers is impacted by physical, compound and natural properties of soil and climatic states of habitats.Earthworm’s biodiversity is straightforwardly influenced by soil attributes (Edwards and Lofty, 1977). These people group impacting factors are soil pH, natural issue, nitrogen, C/N proportion, soil dampness and soil surface. Biodiversity is considered HR (Heywood, 1996). As of late, numerous researcher contemplated the biodiversity and dispersion of worms in the various pieces of the world (Blakemore, 2000, 2002, 2003; Change and Chen, 2004,2005; Blakemore et al. ,2006; Sautter et al. , 2006; Ghafoor et al. , 2008).Present examination was done in Bikaner locale, which is situated in Thar desert of Rajasthan running 28. 01â ° N 73. 19â ° E. . The normal downpour fall around there is 10† to 15† as it were. Subsequently, climatic conditions are unfriendly for creatures. The vast majority of its zone is flooded with tube wells and Indira Gandhi trench. Because of unfavorable conditions from a significant stretch, there is as yet a couple of data about biodiversity and territories. The current investigation will uncovered new fundamental data for additional examination on night crawlers and its nature and utilization of worms in farming area.
