Ayyanadar Arunachalam

Indian Council of Agricultural Research, India

A. Arunachalam is a Tropical Ecologist graduated from the School of Ecology at North-Eastern Hill University, India. His academic mentors were Professor H. N. Pandey and Professor R. S. Tripathi. Both of whom are well known for their contributions to ecology of weeds. Dr. Arunachalam has been a Lecturer in forestry at the North-Eastern Regional Institute of Science and Technology (NERIST), India, since 1996, where, in addition to teaching, he carries out sponsored research in forestry and allied fields. He has been one of the Largest Research Project Grantees at NERIST. He has been sanctioned several research projects by various Indian funding agencies such as Indian Council of Forestry Research and Education, Council of Scientific and Industrial Research, Department of Science and Technology, Ministry of Environment and Forests, Indian Council of Agricultural Research, and G. B. Pant Institute of Himalayan Environment and Development. Within a relatively shorter span of professional experience, Dr. Arunachalam has made notable contributions to soil ecology, ecosystem ecology, shifting agriculture, and land use dynamics in the northeastern India. His doctoral research on the role of detrital mass in soil nutrient restoration in regrowing forests has led to significant conclusions about the least studied belowground components, that is, fine roots and microbial biomass. These components have a greater nutrient immobilization potential and rapid biomass turnover and thus contribute significantly to the organic matter and nutrient dynamics in the degraded and/or regenerating forest ecosystems. His further research demonstrated that such processes vary with different scales of disturbance, ecosystems across seasons, and soil depth. This work is of both basic and applied importance in restoration ecology. Dr. Arunachalam’s recent research is on the characterization of nutrient cycling patterns in hill agroecosystems associated with slash-and-burn agriculture.
