Study of shifts in species distribution in response to climate change, particularly for invasive species, using species distribution models is an important research agenda. We used Biomod 2 (an ensemble of 10 algorithms) to model distribution of a highly invasive species, Parthenium hysterophorus L, under various climate-change scenarios of global, regional (India) and local (J & K State) scales. Suitable niches for P. hysterophorus shrank at global and regional levels under different scenarios, but a reverse trend of niche expansion was predicted at the local (J & K) spacial scale. Further, risk analysis regarding expansion of Parthenium in India and its Himalayan states is likely to help in management of this invasive species.

Professor Zafar A. Reshi works at the Department of Botany, University of Kashmir, Srinagar, Jammu & Kashmir, India. His main research interests include biogeographical perspective of plant invasions, species invasiveness, community invasibility, and distribution modeling of invasive species vis-à-vis climate change. He has published about 150 research papers and book chapters on alien floras of Kashmir Himalaya and India, biology of some common invasive plant species, biotic homogenization and factors contributing to introduction, establishment, and spread of alien plant species. His leadership has established a vibrant school of invasion biology at the University of Kashmir.
