In metapopulations, the maintenance of local populations can depend on source–sink dynamics, where populations with positive growth rate seed populations with negative growth rate. The pattern and probability of successful dispersal among habitats can therefore be crucial in determining whether local populations will become rare or increase in abundance. We present here data on the dispersal st...

robust information of genetic diversity among bt cotton genotypes is still lacking and availability of several marker systems has prompted us to compare their utility for the detection of genetic diversity. here, we report the comparative efficiency of morphological and molecular markers (est-ssrs and issrs) in determining the genetic diversity among 30 pakistani bt cotton genotypes. three diff...

algebraic-delay differential systems and age structured population dynamics Jianhong Wu York University, Canada [email protected] N. Kosovalic, F.M.G. Magpantay, Y. Chen We present some recent results on the fundamental theory and numerical analysis of algebraic-delay differential systems, and discuss its motivation from and applications to structured population dynamics. On the basins of attractio...
