Parameters of metapopulation dynamics of wild soybean originated from different latitudes and their significance of ecological adaptation

Abstract

Abstract: Wild,half-wild and cultivated soybeans originated from different latitudes are transplanted to same area and sowed at different time.The results show that the metapopulation dynamics of three kinds of structural units of Glycine soja can all be simulated with logistic model,where parameter r is positively correlated with latitude, and K is affected by environmental modification.The simulation parameter r of metapopulation dynamics is positively correlated with the reproductive capacity of the plant,which substantiates that metapopulation dynamics of plant has an important significance of ecological adaptation.

Key words: Glycine soja, Metapopulation, Population parameter, Reproductive capacity, Ecological strategy, functional group, spatial process, arthropods, biological diversity, cropland in Northeast China
