Some new schemes have been proposed for evolutionary ecological models, where the variables and the parameters vary simultaneously. These models have low dimensions and high-speed performance. It is studied how periodic changes in the temperature influence the population dynamics and location of the evolutionary stable parameters (i.e., favourable temperatures of the habitat). It is found that evolutionary stable parameters of a single, strongly specialised population are close to the extremal points of the temperature curve. In the model of two interacting prey - predator populations, a slow cyclic drift has been shown possible in the space of those parameters.
