Complexity Analysis and Computation of the Optimal Harvesting for One-Species Population Resources
2007/8/7
The exploitation of renewable resources creates many complex problems for culture, ecology and economics as well. Ascertaining the essentials behind the complex problems is very important. In this pap...
ALMOST PERIODIC SOLUTION FOR A CLASS OF LOTKA-VOLTERRA TYPE $N$-SPECIES ECOLOGICAL SYSTEMS WITH TIME DELAY
Infinite delay diffusion uniform persi
2007/8/7
The uniform permanence and global asymptotic stability of aclass of almost periodic Lotka-Volterra type $N$-speciescompetitive systems with diffusion and delays are investigated. Itis shown that the ...
THE THRESHOLD OF SURVIVAL FOR PREDATOR-PREY VOLTERRA SYSTEM OF THREE SPECIES IN A POLLUTED ENVIRONMENT

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...
GLOBAL ASYMPTOTIC STABILITY IN N-SPECIES COOPERATIVE SYSTEM WITH TIME DELAYS
Time delay positive equilibrium point
2007/8/7
The following n-species cooperative system with time delaysis considered in this paper. It is shown that if the system (1) has a unique positive equilibrium point, then it is globally asymptotically s...
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...
