Abstract
The main models of the competition between populations in a variable environment are described and studied. It is shown that to have a competitive advantage in a time-periodic environment, the (initial) population has to surpass its competitors in terms of productivity with some margin. The constant of a stock can be chosen universal independently of the number of competitors. The constant of stock in a spatially heterogeneous medium is shown to depend on the number of areas in the water body. It increases without limits, so there cannot be a universal constant of a stock.
