Using the method of group biomarking with rhodamine B, new data on migratory patterns (natal dispersal and breeding dispersal) of the pygmy wood mouse (Sylvaemus uralensis (Pallas 1811)) outside its home range were obtained by studying the long-distance locomotion of small mammals on the Eastern Urals Radiation Reserve (Chelyabinsk region, Southern Urals). Long-distance locomotion (1500 m) over 14 hours in the dark part of the day was registered for two yearling males for the first time, allowing for the possible speed of movement of S. uralensis to be estimated. Taking into account that the main activities of rodents occur during evening and morning twilight, the actual time could be considerably shorter. Both dispersers were under-yearling males of different functional status. One of them was a young animal captured during spring reproduction (May 2019) in the year of birth. The other male was young, captured before leaving in winter (October 2021) and not reproducing in the year of birth. Group biomarking by rhodamine B made it possible to estimate the night-time distance and the speed of movement of S. uralensis, also allowing an episode of external contamination by the biomarkers of transient specimens (October 2021) that visited the marking plot, but that did not touch the bait, to be revealed. Our results allow us to conclude that long-distance locomotion of individuals of different functional statuses beyond the home area is normal in S. uralensis. [ABSTRACT FROM AUTHOR] |
