Earthworm biodiversity in an arid region

Earthworm Biodiversity in an Arid Region of Rajasthan, India Among the soil fauna, earthworms have an important role to improve soil texture.

The soil texture plays an important role in water holding capacity. Earthworms have an ability to enhance soil characteristics. Earthworms are also considered as useful indicator of the health of soil ecosystem Edwards and Bohlen, as to their role in soil fertility through fragmentation and mixed up the soil with mineral particle, enhancing microbial activity to breakdown plant organic matter.

The contribution of earthworms in soil turnover, structure formation and serve as a fertility enhancer in different way. Earthworms are useful in land improvement and organic waste management Edwards and Baker, ; Lavelle and Martin, ; Johnson, ; Villenave et al.

International Journal of Pure and Applied Zoology

The distribution and population density of various earthworm species have been correlated with soil type and agriculture land use Haynes et al. The biodiversity of earthworms is influenced by physical, chemical and biological properties of soil and climatic conditions of habitats.

Biodiversity is counted as human resources Heywood, Recently, many biologists studied the biodiversity and distribution of earthworms in the different parts of the world Blakemore, ; Change and Chen, ,; Blakemore et al. Present study was done in Bikaner district, which is located in Thar desert of Rajasthan ranging Therefore, climatic conditions are adverse for organisms.

Most of its area is irrigated with tube wells and Indira Gandhi canal. Due to adverse conditions from a long period, there is still a few information about biodiversity and habitats.

The present study will revealed new basic information for further research on earthworms and its ecology and application of earthworms in agriculture sector.mate the current status of earthworm biodiversity in western arid and semiarid lands of India.

A total of different locations (rural, urban, and sub-urban localities) arid land. Earthworm fauna of this region showed a patchy distribution pattern and the majority of the species were.

Efforts have been made in this study to estimate the current status of earthworm biodiversity in western arid and semiarid lands of India.

A REVIEW ON MOLECULAR MARKERS AS TOOLS TO STUDY EARTHWORM DIVERSITY

A total of different locations (rural, urban, and sub. Suthar S () Earthworm biodiversity in western arid and semiarid lands of India. Environmentalist, Tian G () Biological effects of plant residues with contrasting chemical compositions on plant and soil under humid tropical conditions. are available on earthworm dispersal patterns in arid and semiarid lands of African region.

Earthworms could be a threat to biodiversity

El-Duweini and Ghabbour () reported the earthworm community composition from a few locations of Egypt. Ghabbour and Shakir () estimated the earthworm dispersal and richness patterns in Meriut coastal desert region in Egypt.

Biodiversity of Earthworms and their Distribution in Different Regions of Uttar Pradesh state of India 2 IV.

SAMPLING OF EARTHWORMS Earthworms for the taxonomic studies were collected and hand-sorted as per the techniques of Edwards and. Biodiversity is comprised of the totality of genes, species and ecosystems of a region.

The occurrence of various kinds of flora and fauna in a region reflects its biological diversity or biodiversity. In most parts of the world which are habitable, the living world abounds .
