Effects of Spring-Removal on the Populations of Small Rodents

Abstract

: Changes in numbers, recruitment of new individuals, survival of residents, cohort structure and sex ratios of small rodents were examined for colonized populations in the areas from which individuals were removed in advance in the early spring of 1984 and 1985. For Clethrionomys rufocanus bedfordiae, Apodemus argenteus and A. speciosus ainu, these demographic variables did not differ much from those of control populations. © 1987, JAPANESE SOCIETY OF APPLIED ENTOMOLOGY AND ZOOLOGY.
