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 attributes. It adds to the breakdown of natural issue and discharge plant supplements (Edwards and Bohlen, 1996). Worms are likewise considered as helpful pointer of the wellbeing of soil environment (Edwards and Bohlen, 1992) concerning their job in soil fruitfulness through fracture and stirred up the dirt with mineral molecule, improving microbial movement to breakdown plant natural matter.The commitment of night crawlers in soil turnover, structure development and fill in as a ripeness enhancer in various way. Night crawlers are valuable in land improvement and natural waste administration (Edwards and Baker, 1992; Lavelle and Martin, 1992; Johnson, 1997; Villenave et al. , 1999). The circulation and populace thickness of different night crawler species have been connected with soil type and f arming area use (Haynes et al. , 2003; Sbrina et al. , 2009). The biodiversity of night crawlers is impacted by physical, substance 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 affecting variables are soil pH, natural issue, nitrogen, C/N proportion, soil dampness and soil surface. Biodiversity is considered HR (Heywood, 1996). As of late, numerous scientists contemplated the biodiversity and dispersion of night crawlers 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 region, which is situated in Thar desert of Rajasthan extending 28. 01â ° N 73. 19â ° E. . The normal downpour fall around there is 10† to 15† as it were. In this manner, climatic conditions are antagonistic for living beings. A large portion of its zone is watered with tube wells and Indira Gandhi waterway. Because of unfriendly conditions from a significant stretch, there is as yet a couple of data about biodiversity and environments. The current investigation will uncovered new fundamental data for additional examination on night crawlers and its environment and use of worms in agribusiness part.
