INSIGHT ON INVASIONS AND RESILIENCE DERIVED FROM SPATIOTEMPORAL DISCONTINUITIES OF BIOMASS AT LOCAL AND REGIONAL SCALES

Understanding the social and ecological consequences of species invasions is complicated by nonlinearities in processes, and differences in process and structure as scale is changed.Here we use discontinuity analyses to investigate nonlinear patterns in the distribution of biomass of an invasive nuisance species that could indicate scale-specific o

The purpose of this paper is to explore the spatial heterogeneity of internal migration in China and to discuss the influence of economic, social and environmental characteristics on this demographic process.The overall results suggest that migration in China occurred from inland to coastal areas and from rural areas to urban areas.By stepwise regr
