Functional patterns of life activities of rodent populations in the winter season

Functional patterns of life activities of rodent populations in the winter season The results of 37-year continuous monitoring of basic rodent population parameters (the example of bank vole) are reviewed and generalized using the functional-ontogenetic approach. The role of the environment in synchronizing changes in certain biological indices is demonstrated. A detailed analysis is made of the pattern of change in population parameters during overwintering, including minimization of most biological parameters in this period and its adaptive significance. It is shown that successful winter survival largely depends on the functional status of animals (the type of ontogeny) and also on photoregulation. Consideration is given to the phenomenon of winter breeding and its types in murine rodents. A scheme is presented that describes the integrated (generalized), unspecific adaptive reaction of the population in response to irregular, extreme impacts of natural factors and some (short-term) anthropogenic impacts. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Ecology Springer Journals

Abstract

The results of 37-year continuous monitoring of basic rodent population parameters (the example of bank vole) are reviewed and generalized using the functional-ontogenetic approach. The role of the environment in synchronizing changes in certain biological indices is demonstrated. A detailed analysis is made of the pattern of change in population parameters during overwintering, including minimization of most biological parameters in this period and its adaptive significance. It is shown that successful winter survival largely depends on the functional status of animals (the type of ontogeny) and also on photoregulation. Consideration is given to the phenomenon of winter breeding and its types in murine rodents. A scheme is presented that describes the integrated (generalized), unspecific adaptive reaction of the population in response to irregular, extreme impacts of natural factors and some (short-term) anthropogenic impacts.
