Reliability of Density Estimates Based on Three Night Trappings in the Red-Backed Vole, Clethrionomys Rufocanus Bedfordiae

Abstract

Mean range length and population size on the quadrat increased in the order of three, four, five night trappings. Estimates of population density based on three night trappings were practically reliable since they were not very different from those derived from data of four, or five night trappings. © 1984, JAPANESE SOCIETY OF APPLIED ENTOMOLOGY AND ZOOLOGY.
