“…In agricultural areas, the common vole is generally an openfield rodent and lives in perennial crops (Briner, Nentwig & Airoldi 2005;Janova et al 2011) but colonize cereals crops when sowed, where populations grow rapidly (Janova et al 2011;Bonnet et al 2013). However, agricultural practices such as mowing or ploughing are very detrimental to vole populations (Bonnet et al 2013).…”

Summary1. Population cycles in voles are often thought to be generated by one-year delayed density dependence on the annual population growth rate. In common voles, however, it has been suggested by Turchin (2003) that some populations exhibit first-order cycles, resulting from strong overcompensation (i.e. carrying capacity overshoots in peak years, with only an effect of the current year abundance on annual growth rates). 2. We focus on a common vole (Microtus arvalis) population from western France that exhibits 3-year cycles. Several overcompensating nonlinear models for populations dynamics are fitted to the data, notably those of Hassell, and Maynard-Smith and Slatkin. 3. Overcompensating direct density dependence (DD) provides a satisfactory description of winter crashes, and one-year delayed density dependence is not responsible for the crashes, thus these are not classical second-order cycles. A phase-driven modulation of direct density dependence maintains a low-phase, explaining why the cycles last three years instead of two. Our analyses suggest that some of this phase dependence can be expressed as one-year delayed DD, but phase dependence provides a better description. Hence, modelling suggests that cycles in this population are first-order cycles with a low phase after peaks, rather than fully second-order cycles. 4. However, based on the popular log-linear second-order autoregressive model, we would conclude only that negative delayed density dependence exists. The additive structure of this model cannot show when delayed DD occurs (here, during lows rather than peaks). Our analyses thus call into question the automated use of second-order log-linear models, and suggests that more attention should be given to non-(log)linear models when studying cyclic populations. 5. From a biological viewpoint, the fast crashes through overcompensation that we found suggest they might be caused by parasites or food rather than predators, though predators might have a role in maintaining the low phase and spatial synchrony.

“…Foltête et al (2016). The first scenario is to convert the grassland parcels into cereal crop parcels, because the plowing required before planting cereal crops destroys vole galleries (Bonnet et al, 2013;Jacob & Hempel, 2003;Jug, Brmez, Ivezic, Stipesevic, & Stosic et al, 2008). The second scenario consists in adding hedgerows to all the edges of a given parcel, which is liable to increase the accessibility of avian and mammal predators to vole populations.…”

Highlights  Field actions are planned to reduce functional connectivity of grassland rodents  A parcel-based graph is constructed to prioritize locations for field actions  Parcel rankings determined by removal method and land-use changes are compared  Removal method and land-use changes yield similar rankings via enumerative approach  The two methods differ when rankings are compared by a cumulative approach

“…Green crops also include irrigated cereal fields, a suboptimal habitat because of recurrent disturbance by ploughing in summer after harvest (Jacob et al, 2014). However, cereal could also be an important temporal habitat until harvest or in years of high abundance (Bonnet et al, 2013). More research would be needed to better understand the importance of cereal fields for vole demography, and their role in the invasion of agricultural areas.…”

Factors associated with the colonization of agricultural areas by common voles Microtus arvalis in NW Spain

The common vole, considered a rodent pest when overabundant in agricultural areas, was traditionally absent from the agricultural plains of Castilla-y-León, NW Spain. However, it rapidly invaded ca. 50.000 km 2 of agricultural land, where regular outbreaks have caused crop damages and conflict with farmers. To better understand the factors that triggered this massive invasion of previously unoccupied habitats, we studied the associations between the common vole range expansion and changes in climate and land uses in the region since the 1970s. We found long-term trends in climate, with some changes that could have helped the range expansion (increased fall precipitation and winter temperature) and other changes that may have impaired it (reduced precipitation and increased summer temperatures). Dramatic changes in land use also took place prior to and during the invasion period (marked increases in irrigated and green herbaceous crops such as alfalfa, which are amongst the most favourable habitats for voles). We found strong associations between changes in vole distribution and the extent of green crops (irrigated crops and alfalfa) at regional level. The probability of a given agrarian county to be colonized increased with the extent of green crops, particularly so when vole presence in neighbouring counties was lower, and tended to decrease with increasing livestock abundance. Land use changes, especially increases in irrigated crops and alfalfa, appear to be one of the main drivers behind the range expansion. We discuss these findings in relation to the social conflicts and management challenges that arose from the recent invasion of agricultural areas by crop-damaging common voles.
