The Effect of Differentiation of Prey Community on Stable Coexistence in a Three-Species Food--Web Model
Intraguild predation Immobilization Alternative resource Multiple resource traits Stable coexistence
2012/4/28
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...
STABILITY AND FLUCTUATIONS IN A THREE SPECIES SYSTEM: A PLANT WITH TWO VERY DIFFERENT POLLINATORS
Pollination mutualism population dynamics competition mathematical models
2010/3/26
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...
MEASUREMENT OF THE SWIMMING BEHAVIOR OF THREE SPECIES OF SCYPHOMEDUSAE IN SOUTHERN NEW ENGLAND ESTUARIES
scyphomedusan animal video methods
2009/5/6
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...
Annual recruitment of three species of tide-pool fishes is driven by variation in springtime coastal hydrodynamics
Annual recruitment variation springtime coastal hydrodynamics
2014/4/17
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...
Influence of Ionizing Radiation on Antioxidant Enzymes in Three Species of Trigonella
antioxidant enzymes ascorbate peroxidase superoxide dismutase glutathione reductase catalase irradiation gamma stress
2008/12/25
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...
Periodic Solution of a Nonautonomous Diffusive Food Chain System of Three Species with Time Delays
diffusive food chain system positive periodic solution
2007/12/11
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 THRESHOLD OF SURVIVAL FOR PREDATOR-PREY VOLTERRA SYSTEM OF THREE SPECIES IN A POLLUTED ENVIRONMENT
Population persistenceextinction toxican
2007/8/7
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...
