Abstract: Permanent marks such as ear tagging and passive integrated transponder tags have been successfully used in small-mammal mark鈥搑ecapture research. However, permanent marks can influence small mammal behavior and promote infection. Hair dyes may be favored for short-term mark鈥搑ecapture studies because they are low-cost, can be applied easily, and are less damaging to marked individuals. Our objective was to determine the longevity of an animal hair dye marker placed on small mammals. Our study was conducted at the 无忧短视频 Biological Preserve in 无忧短视频, PA and consisted of two transect lines, each with 10 Sherman traps checked twice a week over 3 months. We captured 27 individuals and marked each of them once with hair dye. Hair dye longevity was monitored via photodocumentation of recaptured individuals. Results showed that the hair dye can be used to distinguish individuals for up to 60 days in short-term mark鈥搑ecapture studies of small mammals.
