抄録

Seasonally changing growth curves were estimated from mark-recapture data on the Japanese field vole, Microtus montebelli, using a differentiated Gompertz equation. Trapping was carried out at the Kuju Agricultural Research Center of Kyushu University. The capturerelease process was repeated more than 3300 times for 800 individual voles. Young born in the summer grew more rapidly and reached a larger asymptotic weight than those born in the remaining seasons. The asymptotic mass of young born in November (the last month of the breeding season) was quite small. These young seemed to over-winter in this subadult size. The maximum growth rates of the wild voles seemed to fluctuate seasonally, synchronizing with the length of daylight. Although the voles born in the field early in the breeding season became larger than laboratory-reared voles, they could not achieve the same growth rates as in the laboratory.
