Discrete Models for Intraspecific Competitions (Kbenesh
Blayneh, Florida A&M University)
Abstract: A coupled pair of first order nonlinear discrete hierarchical
age-structured models are applied to study two modes of intraspecific
competitions. Several comparisons of the dynamical outcomes of the two
competitions are made. These include existence and uniqueness of
nontrivial equilibria, type of convergence (monotone or oscillatory),
and the impact of environmental conditions on these results. Also, the
effect of dispersion to and from neighboring habitatsevel are studied.
