The Beverton–Holt model with periodic and conditional harvesting
Al-Sharawi, Ziyad; Rhouma, Mohamed Ben Haj (Taylor & Francis Online, 2009)In this theoretical study, we investigate the effect of different harvesting strategies on the discrete Beverton–Holt model in a deterministic environment. In particular, we make a comparison between the constant, periodic ... -
Coexistence and extinction in a competitive exclusion Leslie/Gower model with harvesting and stocking
Al-Sharawi, Ziyad; Rhouma, Mohamed Ben Haj (Taylor & Francis Online, 2009)The principle of competitive exclusion states that when the competition between species is sufficiently strong, only the dominant species survives. In this paper, we examine the strategies of using stocking and harvesting ... -
The Discrete Beverton-Holt Model with Periodic Harvesting in a Periodically Fluctuating Environment
Al-Sharawi, Ziyad; Rhouma, Mohamed Ben Haj (Springer, 2010)We investigate the effect of constant and periodic harvesting on the Beverton-Holt model in a periodically fluctuating environment. We show that in a periodically fluctuating environment, periodic harvesting gives a better ... -
The dynamics of some discrete models with delay under the effect of constant yield harvesting
Abu-Saris, Raghib; Al-Sharawi, Ziyad; Rhouma, Mohamed Ben Haj (Elsevier, 2013)In this paper, we study the dynamics of population models of the form xn+1 = xnf(xn−1) under the effect of constant yield harvesting. Results concerning stability, boundedness, persistence and oscillations of solutions are ...
