“…Previously published results are conflicting: agricultural fields have been found to act as significant dispersal barriers (Krohne and Hoch ; Klein and Cameron ), as seasonal barriers where crop height and maturity determine whether they are used as dispersal routes (Cummings and Vessey ; Anderson et al. ), or not as barriers at all (Middleton and Merriam ; Mossman and Waser ). Since we trapped mice between the months of July and September when crops were high enough to provide adequate cover and food for migrating mice, it is possible that the fields were used as seasonal corridors between forest patches.…”

The white-footed mouse (Peromyscus leucopus) has expanded its northern limit into southern Quebec over the last few decades. P. leucopus is a great disperser and colonizer and is of particular interest because it is considered a primary reservoir for the spirochete bacterium that causes Lyme disease. There is no current information on the gene flow between mouse populations on the mountains and forest fragments found scattered throughout the Monteregie region in southern Quebec, and whether various landscape barriers have an effect on their dispersal. We conducted a population genetics analysis on eleven P. leucopus populations using eleven microsatellite markers and showed that isolation by distance was weak, yet barriers were effective. The agricultural matrix had the least effect on gene flow, whereas highways and main rivers were effective barriers. The abundance of ticks collected from mice varied within the study area. Both ticks and mice were screened for the presence of the spirochete bacterium Borrelia burgdorferi, and we predicted areas of greater risk for Lyme disease. Merging our results with ongoing Lyme disease surveillance programs will help determine the future threat of this disease in Quebec, and will contribute toward disease prevention and management strategies throughout fragmented landscapes in southern Canada.

“…It highlights the need to predict edge effects correctly, which, although they have been studied for decades, show a high variability (Ries et al 2004, Pfeifer et al 2017). For example, various effects of habitat edges have been reported for populations of small mammals: edge attraction (Kollmann and Buschor 2003, Mazzamuto et al 2018), edge avoidance (Stevens and Husband 1998, Delattre et al 2009) or neutral effects (Anderson et al 2006). Especially for prey species, edge sensitivity seems to be highly correlated with ground cover and the associated perceived predation risk (Kollmann and Buschor 2003, Loggins et al 2019), as they need to balance the benefits of resource acquisition with the costs of predation.…”

Habitat loss undeniably poses a substantial threat to biodiversity, but whether fragmentation per se drives the loss of species is still widely debated. While negative consequences from fragmentation are often anticipated, many empirical studies report positive effects. However, the intrinsic mechanisms governing species' persistence in fragmented landscapes are not yet understood. In this study we investigated consistent personality-dependent differences in foraging behavior among individuals as a possible mechanism underlying the discrepancy of reported fragmentation effects. We devised a mechanistic individual-based model simulating the home range behavior of a competitive small mammal community based on the availability of a shared resource. Thereby, an individual's risk-taking behavior dictates its foraging decisions at risky habitat edges, an inherent property of fragmentation per se. Our simulations show that differences in risktaking while foraging are potentially a further mechanism contributing to reconcile the fragmentation debate. The first scenario considering risk-seeking communities showed a neutral response towards fragmentation, while the second scenario featuring riskavoiding communities confirmed the negative effects of fragmentation. Notably, the third scenario, simulating behaviorally diverse communities including risk-avoiding and risk-seeking individuals, demonstrated a positive influence of fragmentation on biodiversity. Intraspecific differences in behavior could also enhance the temporal species coexistence (coviability) of communities threatened by an ongoing habitat loss. Our study highlights the importance of recognizing the behavioral composition of populations and communities for estimat®ing fragmentation effects, because differences in risk-taking can influence the coping abilities of animal communities in light of fragmentation.

“…Compared to the forest interior, forest edges can increase the risk of predation and have higher levels of parasitism (Wolf & Batzil, 2004;Séchaud et al, 2021;Dijak & Thompson, 2000). However, forest small mammal species may respond positively to forest edges (Anderson et al, 2006;Buckner & Shure, 1985;Nupp & Swihart, 2000).…”

The Independent Effects of Forest Amount, Fragmentation and Structural Connectivity on Small Mammals' Diversity, Abundance and Occurrence

Although habitat amount, fragmentation, and connectivity are thought to be important drivers of biodiversity, their independent effects have not been evaluated. We selected 70 forested sites in Ontario, Canada, such that forest amount, fragmentation (number of patches), and structural connectivity (treed corridors) in the surrounding x within multiple spatial extents around 70 sampling sites. All relative abundances were standardized. A: relative abundance (number of papers with presence) of P. leucopus per site. B: the relative abundance of T. striatus per site. C: the relative abundance of M. gapperi per site. D: the relative abundance of B. brevicauda per site. E: the relative abundance of T. hudsonicus per site. Forest amount and number of patches are, respectively, the amount of treed area (m2) and the number of distinct patches of treed area in the landscapes surrounding the sampling sites. Patch connectivity is the percentage of patches in the surrounding landscapes connected to the sampled patch (the "focal patches") through corridors. Points and lines indicate landscape variable coefficients. Grey bars indicate delta AICc's for the models containing the landscape variables at each spatial extent. The scale of effect is taken as the scale where the model fit is best, i.e., delta AICc = 0.
