Turing instability in pioneer/climax species interactions.
Systems of pioneer and climax species are used to model interactions of species whose reproductive capacity is sensitive to population density in their shared ecosystem. Intraspecies interaction coefficients can be adjusted so that spatially homogeneous solutions are stable to small perturbations. In a reaction-diffusion pioneer/climax model we will determine the critical value of the diffusion...
متن کاملDensity Estimators for Truncated Dependent Data
In some long term studies, a series of dependent and possibly truncated lifetime data may be observed. Suppose that the lifetimes have a common continuous distribution function F. A popular stochastic measure of the distance between the density function f of the lifetimes and its kernel estimate fn is the integrated square error (ISE). In this paper, we derive a central limit theorem for t...
متن کاملTraveling wave solutions of a reaction diffusion model for competing pioneer and climax species.
Presented is a reaction-diffusion model for the interaction of pioneer and climax species. For certain parameters the system exhibits bistability and traveling wave solutions. Specifically, we show that when the climax species diffuses at a slow rate there are traveling wave solutions which correspond to extinction waves of either the pioneer or climax species. A leading order analysis is used ...
متن کاملHoney bee (Hymenoptera: Apidae) pollination of rabbiteye blueberry Vaccinium ashei var. 'Climax' is pollinator density-dependent.
In a 2-yr field study, mature orchard plants of rabbiteye blueberry (Vaccinium ashei Reade variety 'Climax'), plus potted pollenizers ('Premier') were caged with varying densities of honey bees (0, 400, 800, 1,600, 3,200, 6,400, or 12,800 bees plus open plot) during the bloom interval. The rate of legitimate flower visits tended to increase as bee density increased within a range of 400-6,400 b...
متن کاملTraveling Wavefronts of Competing Pioneer and Climax Model with Nonlocal Diffusion
and Applied Analysis 3 2. Preliminaries It is evident that (0, 0) is a trivial equilibrium of (6). The system (6) has at least four equilibria and at most six equilibria.The existence of nonnegative steady states depends on the locations of the three nullclines: c 11 u + V = z 0 , u + c 22 V = w 1 , u + c 22 V = w 2 . (7) The long-termbehavior of solutions to (6) can be qualitatively different ...
