Birth Rate Effects on an Age-Structured Predator-Prey Model with Cannibalism in the Prey
We develop a family of predator-prey models with age structure and cannibalism in the prey population. It consists of systems of m ordinary differential equations, where m is a parameter associated with new proposed prey birth rates. We discuss how these new birth rates give the required flexibility...

| Summary: | We develop a family of predator-prey models with age
structure and cannibalism in the prey population. It consists of systems
of m ordinary differential equations, where m is a parameter associated with
new proposed prey birth rates. We discuss how these new birth rates give
the required flexibility to produce differential systems with well-behaved
solutions. The main feature required in these models is the coexistence
among the involved species, which translates mathematically into stable
equilibria and periodic solutions. The search for such characteristics is
based on heuristic predation functions that account for cannibalism in
the prey. |
