Abstract
(1) A method is described for estimating migration rates from recapture data by recording movements across internal boundaries of a study site. (2) Application of the method to a grassland population of the snail Cepaea nemoralis indicated an annual adult emigration rate of 26-56% from a 400 m2 plot, and a net loss of c. 10% per year due to collecting disturbance. (3) Correcting for migration had a considerable effect on estimates of population gains and losses, as determined by Jolly's method. (4) Undisturbed migration rates were highest in May and June, but unaffected by population density.This publication has 4 references indexed in Scilit:
