Roads and road verges can potentially have opposite impacts on organisms that move through the landscape. While be habitat for a large number of species, been proposed to act as dispersal corridors, roads barriers movement. This duality has however rarely assessed simultaneously, it is unknown what degree depends amount traffic quality verge. We used fluorescent powdered dye track movements flo...

different discrete models of population dynamics of certain insects have been investigated under various feasible conditions within the framework of nonlinear dynamics. evolutionary phenomena are discussed through bifurcation analysis leading to chaos. some tools of nonlinear dynamics, such as lyapunov characteristic exponents (lce), lyapunov numbers, correlation dimension, etc. are calculated ...
