Bifurcations of a Leslie‐Gower prey‐predator system with ratio‐dependent Holling IV functional response and prey harvesting

Abstract: The dynamics of a Leslie‐Gower prey‐predator system with ratio‐dependent Holling IV functional response and constant harvesting rate of prey are taken into account. The results developed in this article reveal far richer dynamics compared with the system without harvesting. We first make qualitative and bifurcation analysis of the system without harvesting and show that the system has a weak focus of multiplicity at most 2, at which a Hopf bifurcation occurs. However, the system with harvesting has four nonhyp… Show more

“…Interaksi antara dua atau lebih spesies dalam suatu ekosistem merupakan topik yang populer dalam pemodelan matematika karena menyangkut eksistensi dari populasi spesies-spesies tersebut. Salah satu model interaksi antara dua spesies yang memiliki perkembangan pesat dalam pemodelan matematika yaitu model predator-prey, sebagai contoh lihat [1][2][3][4][5][6][7][8]. Selain karena adanya interaksi antara populasi, eksistensi dari suatu populasi juga dipengaruhi oleh adanya infeksi penyakit baik yang mewabah secara tertutup dalam suatu populasi ataupun menyebar lintas populasi.…”

“…To tackle that type of situation, many researchers worked on a predator-prey system with harvesting effects (15) (16) (17) (18). Basically researchers used three types of harvesting and the classification is constant harvesting (19), proportional harvesting (20) and non-linear harvesting (21). In this paper we consider harvested predator and prey population.…”
