“…The distance an individual moved was expressed as mean distance between successive captures (MDBSC), calculated using the program Capture-Mark-Recapture (CMR, Le Boulengé 1987). Juveniles were excluded from all spatial analyses due to a greater likelihood of transient and/or dispersal behavior (Wolff et al 1988;Wolff 1997).…”

Predation directly changes the demographics of prey, generally through a numerical decrease. An indirect effect of predators is alteration of movements and spatial patterns of prey. The relationship between these direct and indirect effects can be tested by excluding predators. Home range size of white-footed mice (Peromyscus leucopus) decreased and home range overlaps increased in the absence of predators. Home range size and overlaps of meadow voles (Microtus pennsylvanicus) did not change despite an increase in vole density. P. leucopus had significantly lower interspecific home range overlaps with M. pennsylvanicus than intraspecific overlaps. The changes in P. leucopus spatial behavior may be an indirect effect of predator exclusion resulting from the increase in M. pennsylvanicus densities.

“…More rodents abandoned their home ranges in the years of low than in the year of high density. In non-cyclic populations, the rate of dispersal is typically higher at low than at high densities (Mazurkiewicz and Rajska-Jurgiel 1975, Jannett 1978, Jones et al 1988, Wolff et al 1988, Bujalska and Griim 1989, Jones 1989, Wolff and Cicirello 1990, Hansson 1991, Chistova 1995, Lukyanov 1995, as a consequence of resource limitation as well as competition for mates or space to breed. Dispersal rates decline with increasing availability of resources.…”

. 1998. Spatial behaviour and population dynamics of woodland rodents. Acta Theriologica 43: 137-161.Population dynamics and spatial behaviour of the vole Clethrionomys glareolus (Schreber, 1780) and the yellow-necked mouse Apodemus flauicollis (Melchior, 1834) were studied for 7 years in woodland of Kampinos National Park, Poland. Mice were more mobile and less site-tenacious than voles. Annual peaks ranged from 9 to 104 voles and from 4 to 62 mice per ha. The highest densities of both species were preceded by winter breeding. The greatest movement range and the longest distance moved were observed in the years of low density, whereas in the high density year both species were least mobile and most site-tenacious. Intensive movements in the low density years led to early maturation, high turnover rates, and probably increased mortality. Low mobility and high site tenacity in the high density year enhanced population growth and suppressed maturation. Increasing density and cessation of breeding accounted for declining juvenile recruitment. Differences in movement patterns between years of low and high density were coupled with differences in the autumn age structure and winter mortality of both species.

“…Nevertheless, these results are more useful than estimates of Nm derived from F ST (Austin et al 2004). We also tested whether a greater proportion of males, specifically younger males (\18 g; Cummings and Vessey 1994), are immigrants in small patches compared to large patches since juvenile males have been documented as the primary disperser in this species in field-based studies (e.g., Wolff et al 1988) and in a genetic study (Mossman and Waser 1999).…”

Genetic estimates of immigration and emigration rates in relation to population density and forest patch area in Peromyscus leucopus

An emerging pattern is that population densities of generalist rodents are higher in small compared to large forest patches in fragmented landscapes. We used genetically based measures of migration between patches to test two dispersal-based hypotheses for this negative densityarea relationship: (1) emigration rates from small patches should be relatively lower compared to large patches (''inhibited dispersal hypothesis''), or (2) immigration rates should be higher into small than large patches (''immigration hypothesis''). Neither hypothesis was supported using data on dispersal inferred from eight microsatellite loci for 12 populations of Peromyscus leucopus in six small (1.3-2.7 ha) and six large (8-150 ha) forest patches. Emigration rates were not lower from and immigration rates were not higher into small than large patches. In fact, contrary to both hypotheses, emigration rates were higher from populations of P. leucopus in small compared to large patches. Based on a combination of genetic and field data, we speculate that higher reproduction in smaller patches resulted in higher densities which led to higher emigration rates from those patches. Rates of reproduction (presumably driven by better habitat conditions in smaller patches), rather than dispersal, seems to drive density differences in forest patches. We conclude that smaller forest patches within an agricultural matrix act as a source of individuals, and that migration rates are fairly high among forest patches regardless of size.
