Food webs with intraguild predation (IGP) are widespread in natural habitats. Their adaptation and resilience behaviour is principal for understanding restructuring of ecological communities. In spite...
We present a multi-species model of one plant with two nectivore pollinators. This system has mutualism between the plant and the pollinators, and competition for food between pollinators. Both polli...
The swimming behavior of three scyphomedusan species was observed and recorded on video by scuba divers in natural daytime lighting with minimal interference to the medusae. The mean percentage of tim...
Using an 18-yr time series of annual recruitment of three tide-pool fishes, Clinocottus globiceps, Clinocottus embryum, and Oligocottus maculosus, we investigated the relationship between recruitment...
The response of three species of Trigonella, namely, Trigonella stellata, Trigonella hamosa and Trigonella anguina to gamma irradiation stress was investigated with respect to antioxidant enzyme induc...
By using the continuation theorem of coincidence degree theory, the existence of a positive periodic solution for a nonautonomous diffusive food chain system of three species. { dx_1(t)/dt = x_1(t)[r_...
The effects of toxicants on two kinds of Volterra systems have been studied.One is a community consisting of two competitive predators and one prey; another,one predator and two competitive preys. The...
In this paper we consider the Predator-Prey model for three species in which the right-hand sides are periodic in time. A set of easily verifiable sufficient conditions is obtained for the existence o...
