Predation and self-regulation explain microtine density cycles. Modeling suggests strong trophic interactions, likely specialist predation, are key drivers of these rodent population fluctuations.

Area of Science:

  • Ecology
  • Population Dynamics
  • Mathematical Biology

Background:

  • Microtine rodents exhibit cyclical population fluctuations, known as microtine density cycles.
  • Previous hypotheses have explored various factors, but a comprehensive explanation remains elusive.

Purpose of the Study:

  • To test a hypothesis integrating predation and self-regulation for microtine cycles.
  • To model the underlying mechanisms driving the observed population dynamics.

Main Methods:

  • Analysis of current ecological data on microtine populations.
  • Development of mathematical models incorporating trophic interactions and density dependence.
  • Comparison of model outputs with time series data of northern European microtines.

Main Results:

  • The study supports a hypothesis where both predation and self-regulation are essential for microtine cycles.
  • Modeling indicates that strong trophic interactions, specifically specialist predation, are crucial for generating observed population dynamics.
  • Delayed density dependence and two-dimensional cyclic time series structures were reproduced by the models.

Conclusions:

  • A combination of strong specialist predation and moderate self-regulation adequately explains the complex dynamics of microtine rodent populations.
  • Trophic interactions play a significant role in generating the dimensionality observed in northern microtine population cycles.
