“…This pattern suggests a dynamic interplay between localized foraging behaviour and a strong innate tendency toward movement. It corroborates the increasingly well-documented vagility of small mammals (Bowman et al 1999;Maier 2002;Rehmeier et al 2004;Jung et al 2005), which could be a key attribute for population connectivity at broader spatial scales.…”

“…This 4287 ± 10 m single-season, non-homing movement by an adult male Deer Mouse exceeds movements of 3044 ± 60 m and 1768 m reported by Jung et al (2005) and Bowman et al (1999) in similar habitat. Both Jung et al (2005) and Bowman et al (1999) reported long-distance movements of subadult male Deer Mice in autumn that were presumed to be dispersal from natal range.…”

“…He disposed of the carcass before we could verify the identity. However, given mouse 923's established propensity for rapid long distance movements (927 ± 3 m in five days between grids 1 and 2), the absence of other sources of tagged animals, the caretaker's familiarity with the project, the lack of plausible means for assisted movement, and the numerous previous instances of long-distance movements by this species (Bowman et al 1999;Jung et al 2005), we are confident that the mouse lethally trapped and reported as Deer Mouse 923 was indeed the same individual that we captured in grids 1 and 2.…”

Canadian Field-Naturalist 129(2): 181-182.We report a single-season, non-homing movement of 4287 ± 10 m by an adult male Deer Mouse, Peromyscus maniculatus, in western Maine, United States, in summer 2014. The movement was achieved in two stages: 927 ± 3 m in four days and an additional 3360 ± 10 m in 44 days. This is approximately 40% greater than the previously documented maximum linear movement for an individual of this species.

Variation in space and time: a long-term examination of density-dependent dispersal in a woodland rodent

et al. 2020

Dispersal is a fundamental ecological process that can be affected by population density, yet studies report contrasting effects of density on propensity to disperse. In addition, the relationship between dispersal and density is seldom examined using densities measured at different spatial scales or over extensive time series. We used 51 years of trapping data to examine how dispersal by wild deer mice (Peromyscus maniculatus) was affected by changes in both local and regional population densities. We examined these patterns over both the entire time series and also in 10-year shifting windows to determine whether the nature and strength of the relationship changed through time. Probability of dispersal decreased with increased local and regional population density, and the negative effect of local density on dispersal was more pronounced in years with low regional densities. In addition, the strength of negative density-dependent dispersal changed through time, ranging from very strong in some decades to absent in other periods of the study. Finally, while females were less likely to disperse, female dispersal was more density-dependent than male dispersal. Our study shows that the relationship between density and dispersal is not temporally static and that investigations of density-dependent dispersal should consider both local and regional population densities.

16Dispersal is a fundamental ecological process, and population density has been observed as a 17 driver of dispersal in various taxa. Conflicting examples of positive and negative density-18 dependent dispersal, however, leave little consensus regarding any general effects of density on 19 dispersal. Deer mice (Peromyscus maniculatus) have exhibited both negative and positive 20 density-dependent dispersal. Using 51-years of data on P. maniculatus live-trapping 21 abundances, we examined the spatial scale of density-dependent dispersal as well as its temporal 22 stability within this long time-series. We examined these patterns over both the entire time-series 23 and also in ten-year shifting windows to determine whether the nature and strength of the 24 relationship changed through time. Overall, the probability of dispersal decreased with increased 25 local and regional population density, and the negative effect of local density on dispersal was 26 more pronounced in years with low regional densities. Females were less likely to disperse, but 27 female dispersal was more density-dependent than male dispersal. Additionally, the strength of 28 negative density-dependent dispersal changed through time, from very strong in some decades to 29 absent in others. Our study shows that the relationship between density and dispersal is not 30 temporally static and that studies of density-dependent dispersal should consider both local and 31 regional population densities. As well, while male-biased dispersal is often considered 32 ubiquitous in mammals, we demonstrate that male and female dispersal may have differing 33 levels of density-dependence. Finally, our study highlights the importance of accounting for both 34 local and regional processes in natural systems as these types of long-term, spatially broad 35 examinations of dispersal are crucial if spatial processes are to be represented adequately and 36 accurately in population modelling and theory. 37
