“…The most intriguing finding was the absence of significant factors such as sex, maturity, and the availability of additional food. Many studies have shown that the dispersal of small rodents and is skewed by sex and/or age (Dice and Howard 1951;Lidicker 1985;Smith 1997;Borkowska et al 2010;Ishibashi et al 2013;Stephens et al 2013;Grigorkina and Olenev 2018;Schipanov et al 2019). Existing data on bias by sex in excursions are inconsistent (Crawley 1969;Madison 1980).…”

“…After the live capture survey, a one-time marking session with biomarkers was conducted using tetracycline (TC) and rhodamine B (RB) on plots 2 and 5, respectively. TC is an antibiotic that has been employed in field studies for group marking of animals (Crier 1970;Lindsey et al 1971;Inoue et al 2007;Tolkachev 2016aTolkachev , 2016bGrigorkina and Olenev 2018). Individuals consuming bait with TC obtain a mark that appears as yellow fluorescence in bones and teeth under UV light (Milch et al 1957).…”

“…The study of dispersal in small mammals faces significant methodological difficulties, as dispersal is a rare and short-term event in the lifetime of an individual. During the dispersal process, the movement distances can exceed the typical home range size for a species (Bol'shakov and Bazhenov 1988;Szacki andLiro 1991, 2002;Tolkachev 2016aTolkachev , 2016bGrigorkina and Olenev 2018). The probability of a particular distance decreases exponentially with increasing distance from the home range (Anderson 1989).…”

Long-distance movements (LDMs) of small mammals (SMs) are complex phenomena that cover both dispersals and excursions occurring outside the home ranges of individuals. Owing to methodological difficulties, there are a lack of data on LDMs for SMs. In this study, we aimed to determine the factors that influence the LDMs of different mouse-sized rodents and shrews in the Ural taiga (Sverdlovsk region, Russia). We conducted a field experiment in a boreal forest using individual- (capture–marking–recapture [CMR]) and group- (biomarkers: tetracycline and rhodamine B) marking methods, in conjunction with additional feeding. The species, sex, maturity, plot ID, additional food supply, species abundance indices, individuals/100 trap-nights indices in the capture plot, and body weight of each animal were analyzed as predictors of LDMs. We identified 89 individuals from six species that moved at distances of 250, 350, and 500 m. LDMs varied with the particular species and its population abundance. Most of the observed movements were excursions and not dispersal events. Applying mathematical simulations to the obtained empirical data facilitated estimation of the intensity of the excursion activity for different species. We present the 1st excursion data on Sylvaemus uralensis (Pallas, 1811), Microtus arvalis (Pallas, 1778), and Sorex caecutiens (Laxmann, 1788). The detected excursion distance (250 m) for Myodes glareolus (Schreber, 1780) is the maximum excursion distance known for this species. We demonstrate that with comparable labor and time costs, the use of biomarkers makes it possible to detect many more LDMs than CMR allows.

First time in the East Urals radioactive trace zone (EURT) (Chelyabinsk region, Southern Urals) small mammals from natural population with rhodamine B (RB) label, received in last year were revealed. The aim of this study was to estimate long-distance movements (LDM) of small mammals during the autumn–winter season by method of group marking with bait containing RB. One-time ingestion of bait with RB ensures systemic marking, which fixed in keratin-containing structures (hairs, claws, vibrissae). Retention time of RB-label for wood mouse (Sylvaemus uralensis Pallas, 1811) was 338 days, for common shrew (Sorex araneus Linnaeus, 1758) – 312 days, for red-backed vole (Myodes rutilus Pallas, 1779) – 251 days. It has allowed for the first time to estimate LDM of wintering individuals during autumn–winter season from EURT zone to adjacent territories and vice versa. It was found that S. uralensis are able to settle within 10800 m, M. rutilus – 9500 m, S. araneus – 9300 m. These data are the maximum recorded distance for these species. There is a predominance of females both among wintering settled animals and distant migrants. Probably LDM of females is evolutionary more favorable to population as they serve as the potential reserve of a genetic variety. LDM provides spatial and functional connectivity of mouse-sized mammal’s populations and possibility of genetic information exchange between population groupings on both the impact and background territories. The technique of group marking with bait containing RB has shown the efficiency at research of spatial structure of small mammals during the autumn-winter period. It is advisable to include it in monitoring system in areas of local technogenic pollution as well as to use it to calibrate samples of animals in the study of remote effects of radiating and other toxic effects.

“…The main determinants of dispersal include the range of movements of the species and its ability to overcome various landscape discontinuities. Many species of small mammals, including murine rodents, are known to be able to travel distances of several kilometres (Allred, Beck, 1963;Clark et al, 1988;Dickman et al, 1995;Jung et al, 2005;Tolkachev, 2016a;Grigorkina, Olenev, 2018). For example, the maximum distance recorded for mouse-sized mammals is 14,730 m (Maier, 2002).…”

We studied the long-distance dispersal of two species of shrews – Laxmann's shrew (Sorex caecutiens) and the pygmy shrew (Sorex minutus). Group marking with bait containing rhodamine B was used. These were the first data obtained on the long-distance movements of the pygmy shrew (n = 5), which extended from 475 m to 2570 m in a straight line. In the course of dispersion, Laxmann's shrews (n = 12) moved distances of up to 4500 m, which is the maximum movement distance known for this species.
