About universal constants of the stock in models of competition

The main models of the competition of populations in the changing environment are proved and investigated. It is shown that in the periodic temporary environment for competitive advantage productivity (initial) population has to surpass productivity of the competitors with some stock. The constant of a stock can be chosen universal, not depending on number of competitors. It is established that spatially heterogeneous midium the constant of a stock depends on number of areas in a reservoir. It beyond all bounds therefore is no universal constant of a stock.
