Managing Populations with Unimodal Dynamics
In this work, we analyzed the impact of interventions on populations which exhibit unimodal dynamics. The six landmarks that characterize the “shape” of the unimodal reproduction curve f x of the difference equation, 1 n n X f X , are defined and used in order to examine and determine the behavior of dynamics of populations. By using the Li-Yorke criterion for determination of chaos...
متن کاملUnimodal Time-symmetric Dynamics
Time-symmetric cycles are defined. Unimodal time-symmetric cycles are classified. A one-parameter family of maps of the closed unit interval that exhibits this classification is given. 1. Introduction. In one-dimensional dynamics, the maps that are studied are usually noninvertible. The initial reason for studying these maps was that they had complicated behavior that was reminiscent of diffeom...

متن کاملOn Approach - Rate Conditions in Unimodal Dynamics
The relation between recurrent behavior and the absence of a stable periodic orbit is discussed for unimodal maps. Almost all periodic maps are non-recurrent and almost all non-periodic are recurrent. Still one feels that the critical orbit cannot accumulate to quickly on the critical point, if it wants to avoid an asymptotic periodic behavior. We obtain exponential bounds of this type in terms...
متن کاملManaging wildlife populations with uncertainty: cormorants Phalacrocorax carbo
Managing wildlife populations for conservation, control or harvesting involves uncertainty. Nevertheless, decisions need to be made based on the available evidence. The two main sources of uncertainty in population modelling are parameter estimates and structural uncertainty. Structural uncertainty in models is not included as often as parameter uncertainty.We present an approach where paramete...
