NONLINEAR DYNAMICS OF PLANT COMMUNITIES:
OCCURRENCE OF SPATIAL HETEROGENEITY (SPOTTINESS)
Efim Frisman, Alexey Kolobov
In this report we consider two mathematical models for spatial-temporal dynamics of plant communities. The first model refers to the analytical class; it represents the integral-differential equations system, and the second one is imitation computer program. It was shown that increasing the competition for resources (primarily involving light) intensity pressure leads to the processes of chaotic self-organization and rise of aggregately structured heterogeneous (spotty) spatial distributions.
