Effects of food addition on the seasonal density‐ dependent structure of bank vole Clethrionomys glareolus populations
Summary Population growth rates of bank vole populations in northern Finland were studied using long‐term Capture–Mark–Recapture (CMR) data from two large grids (food‐addition and control), in 1982–94. A marked seasonal structure was found for direct density dependence, with a stronger density depen...
