Changes in the Distribution of Lesser Adjutant Storks (Leptoptilos javanicus) in South and Southeast Asia: A Plausible Evidence of Global Climate and Land-use Change Effect

Kapil K. Khadka and Ranjit Pandey    

Abstract: Species distribution Models (SDMs) illustrate the relation between species and environmental variables. In an attempt to model the historical and current distribution of Lesser Adjutant Stork (Leptoptilos javanicus) and gain qualitative insight into range shift, maxEnt modeling approach was applied. The model was projected into maps to illustrate the variation in spatial distribution of the species in South and Southeast Asia over time. A distributional shift was observed towards the north accompanied by range contraction to the south and expansion to the north. Besides, annual precipitation and temperature of the coldest period of a year appeared to be the major climatic determinants of species distribution. It provides plausible evidence of global climate and land-use change effect on the bird’s distribution and suggests avenues for further research.
