Abstract: | The use of arboreal runways by the rodents, Apodemus sylvaticus, A. flavicollis and Clethrionomys glareolus , was investigated in the deciduous woodland of Woodchester Park, Gloucestershire, England. Longworth live traps were tied to horizontal and inclining branches of trees and shrubs up to 3 m. Arboreality was extensive in all three species, although less in C. glareolus than in either Apodemus species. There was no indication that A. flavicollis consistently used arboreal runways more than A. sylvaticus but the data suggest that the peak of arboreal activity of these congeners occurred in different seasons. In A. sylvaticus , males were more arboreal than females and adults were more arboreal than juveniles. In, 4. flavicollis , juveniles were trapped significantly more often on arboreal runways than adults. The reasons for, and the consequences of, arboreality in small rodents are discussed. |
