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 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 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 ...
متن کاملOwnership Structure, Absorptive Capacity, and Innovation: Planting Vs Harvesting Innovation
This dissertation investigates the main research question: Which classification of innovation explains the heterogeneous timing of revenue realization? Given the significance of financial gain, researchers are recommended to pay attention to whether innovation outcomes result in commercial gains in the short term. Following this notion, a new category of innovation, planting and harvesting, is ...
متن کاملContrasting Regeneration Strategies in Climax and Long-Lived Pioneer Tree Species in a Subtropical Forest
1: This study investigated 15 coexisting dominant species in a humid subtropical evergreen broad-leaved forest in southwest China, consisting of long-lived pioneers and climax species occurring in natural and disturbed regimes. The authors hypothesized that there would be non-tradeoff scaling relationships between sprouting and seed size among species, with the aim of uncovering the ecological ...
