چکیده

The Rosenzweig-MacArthur (1963) criterion is a graphical criterion that has been widely used for elucidating the local stability properties of the Gause (1934) type predator-prey systems. It has not been stated whether a similar criterion holds for models with explicit resource dynamics (Kooi et al. (1998)), like the chemostat model. In this paper we use the implicit function theorem and implicit derivatives for proving that a similar graphical criterion holds under chemostat conditions, too.

A Stoichiometricmodel of Two Producers and One Consumer

In this paper, we consider a stoichiometric population model of two producers and one consumer. It is a generalization of the Rosenzweig-MacArthur population growth model, which is a one-producer, one-consumer population model without stoichiometry. The generalization involves two steps: 1) adding a second producer which competes with the first, and 2) introducing stoichiometry into the system....

A numerical method for discrete fractional--order chemostat model derived from nonstandard numerical scheme

‎In this paper‎, ‎the fractional--order form of three dimensional chemostat model with variable yields is introduced‎. ‎The stability analysis of this fractional system is discussed in detail‎. ‎In order to study the dynamic behaviours of the mentioned fractional system‎, ‎the well known nonstandard (NSFD) scheme is implemented‎. ‎The proposed NSFD scheme is compared with the forward Euler and ...

On Global Stability of a Predator-Prey System

A two-dimensional model for predator-prey interaction is proposed. Two criteria for global stability of the locally stable equilibrium are presented. These make the graphical method of Rosenzweig and MacArthur more significant.

Evaluation of Models to Describe Temporal Growth in Local Chickens of Ghana

The logistic, Gompertz, Richards and asymmetric logistic growth curve models were fitted to body weight data of local Ghanaian chickens and French SASSO T44 chickens. All four growth models provided good fit for each sex by genotype growth data with R2 values ranging from 86.7% to 96.7%. The rate constant parameter, k, ranged between 0.137 and 0.271 and were significantly different from zero fo...
