“…Dispersal distance depends on the home range size and exploration rates (Johnson 1988, Jones 1989, Wegner and Merriam 1990. Resource deficiency, however defined, causes an increase in dispersal rates (Jones et al 1988, Wolff and Cicirello 1990, Brandt 1992. Although dispersal increases the risk of predation, the chance of finding resources is also increased.…”

“…Resource deficiency accounts for increased mobility, aggressiveness and territorial tendencies in animals (Bondrup-Nielsen 1985, Ims 1987, Ostfeld 1985, Anderson 1989, Hansson 1991, Brandt 1992. High mobility of rodents caused high emigration rates and early juvenile maturation.…”

“…Dispersal rates decline with increasing availability of resources. Superabundant food supply (seed crop, supplemental feeding) inhibit emigration and allow for immigration into food rich patches (Boutin 1990, Brandt 1992, Lofgren et al 1996. As the territory size is a function of habitat quality (Bujalska 1975, Ostfeld 1985, Bondrup--Nielsen 1986, Jones 1990, good food conditions relax competition for space (Ims 1987, Ylonen et al 1988.…”

“…A local increase in the available food supply often causes an influx of immigrants (Andrzejewski 1963, Hansson 1971, Flowerdew 1976, Boutin 1990, Brandt 1992, Lófgren et al 1996. As a result of heavy seed crops or supplying additional food, rodent densities are high in the following years (Zejda 1962, Bujalska 1975, Andrzejewski and Mazurkiewicz 1976, Jensen 1982a, Mazurkiewicz and Rajska-Jurgiel 1987, Pucek et al 1993.…”

. 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.

“…However, the authors stressed the need to incorporate the effects of the introduction of immigrants on resident males. Indeed, males and females have different strategies when interacting with conspecifics (Brandt 1992, Palanza et al 1996, Kahlenberg et al 2008. For resident males, immigrant males represent competitors for mating, while immigrant females represent an additional mating opportunity, so it should be in the resident male's interest to behave aggressively towards males, but not towards females (Back et al 2002).…”

Ultimate causes of animal dispersal have been hypothesized to benefit the dispersing individual because dispersal reduces competition for local resources, potential for inbreeding, and competition for breeding partners. However, proximate cues influence important features of dispersal behavior, including when dispersal occurs, how long it lasts, and direction, straightness, and distance of the dispersal path. Therefore, proximate cues that affect dispersal influence ecological processes (e.g., population dynamics, disease transmission, gene flow). We captured and radio‐marked 277 juvenile female white‐tailed deer (Odocoileus virginianus), of which 27 dispersed, to evaluate dispersal behavior and to determine proximate cues that may influence dispersal behavior. Female dispersal largely occurred at 1 year of age and coincided with the fawning season. Dispersal paths varied but generally were non‐linear and prolonged. Physical landscape features (i.e., roadways, rivers, residential areas) influenced dispersal path direction and where dispersal terminated. Additionally, forays outside of the natal range that did not result in dispersal occurred among 52% of global positioning system (GPS)‐collared deer (n = 25) during the dispersal period. Our results suggest intra‐specific social interactions and physical landscape features influence dispersal behavior in female deer. Female dispersal behavior, particularly the lack of directionality, the semi‐permeable nature of physical barriers, and the frequency of forays outside of the natal range, should be considered in regard to population management and controlling the spread of disease. © 2016 The Wildlife Society.
