This study demonstrates that, even in a mainland context, a systematic trapping strategy can have a substantial impact on the density and distribution of a damaging species, in this case allowing the restoration of a native prey species. Invasive mustelids Mustelidae in general have been considered difficult to control or eradicate King et al.
In the island context, the probability of reinvasion, and therefore the need to repeat removal effort, was related to the degree of isolation from source populations Bonesi and Palazon , blurring the distinction often made between eradication and control.
On larger landmasses, the ambition of permanent eradication is more distant and intermediate steps that address sub-regions may be of limited value and economically untenable Zabala et al. Although fur farming the original source of the wild mink population is now prohibited by law in Britain Fur Farming Prohibition Act , in much of Europe fur farming remains a source of reinvasion Bonesi and Palazon In this mainland context, the impact of mink removal on mink numbers, and benefits to prey, are unclear.
This uncertainty influences long-term policy and resource allocation Reynolds , Zabala et al. Therefore, quality evidence is needed to inform and defend policy. We aimed to develop an evidence-based strategy for control of American mink, especially in a mainland or continental context where the probability of reinvasion is high.
Kill-trapping techniques for mink are long established in North America e. The effectiveness of either kill- or live-trapping to control mink numbers could be inferred only from catch-per-unit-effort or field sign surveys.
In previous work, we found that track-recording mink rafts, which accumulated tracks on a clay-and-sand substrate over periods of 7—14 days, were a more sensitive detector of mink presence than were either field sign surveys or incidental sightings and, if rafts were used systematically, the probability of detecting each mink present was high, even at low population density Reynolds et al.
This suggested a targeted control strategy in which traps were deployed only where mink were recently detected, economizing on daily trap-checking effort Porteus et al.
The UK clade was given a normal distribution truncated at lower and upper limits of 7. The analyses were repeated without the prior on the UK clade to test the effect of the priors on the posterior distributions.
Multimodal distributions are considered to correspond to a condition of demographic stability or multiple colonization, whereas recent sudden population expansions would be observed by unimodal patterns Slatkin and Hudson, Results Phylogenetic Analysis and Genetic Diversity A total of nucleotide positions of the target Cytb were resolved in all individuals from around the UK. We found a total of five haplotypes, four of which are unique to known European haplotypes all sequences have been deposited in GenBank; Table 1 , Figure 2A , and all positions were parsimony informative.
Haplotype diversity we found was similar to that reported in continental Europe UK 0. Haplotype map minimum spanning network. Numbers along the branches correspond to the number of mutational steps observed between haplotypes, no number is one mutational step, size of the circles correspond to the number of populations for each haplotype. A Number for UK haplotypes given in the circles correspond to Table 1. B D-loop haplotypes are colored as found in key. In total, UK dormice show a 0.
The Cumbria sample the most northerly extant population in England forms a cluster with this central haplotype group. Haplotype 39 Table 1 was found in 11 populations and is the most frequent group sampled in this study that also form a grouping with CNE clade Figure 2A.
Maximum-likelihood ML topology for concatenated sequences Cytb, D-loop, and bfibr. The numbers on the branches indicate the bootstrap values. A bp fragment of D-loop was sequenced for individuals Table 1. Haplotype diversity 0. The bfibr bp nuclear marker was sequenced for all individuals around the UK, Lithuania and France no other sequences are available on GenBank for common dormice.
This gene was found to be monomorphic across all populations in the UK, however there was divergence between the UK and continental European populations. As such bfibr and D-loop sequences were only further analyzed as concatenated sequences along with Cytb. Concatenated sequence analysis bp showed a total of 7 unique haplotypes, and had higher resolution to reveal regional genetic variation than that of Cytb alone Figure 2B.
For Cytb, only one mutation is observed between sequences as seen in both the ML tree and haplotype network Figures 2 , 3 , whilst for D-loop there are four mutational steps present Figure 2B. Samples sequenced from Suffolk in East England show a close genetic grouping with each other, especially in the D-loop haplotype network Figure 2B.
Two populations sampled in Suffolk were part of a national re-introduction programme and clustered separately from natural populations in Suffolk by a single mutation.
Based on our Cytb analysis, these reintroduced populations group with the South East and North England clade Figure 2A , likely due to the genetic source of these populations from Southern England.
Based on our D-loop analysis, one reintroduced Suffolk population Bradfield falls into the CE clade and the second reintroduced population groups with another Suffolk population Bonny; Table 1 , Figure 2B. The last population is geographically close less than 1 km with available connective habitat to the population in which it forms a haplotype connection with see Figure 2B , but to assess whether there is evidence of gene flow or whether this is consistent with ancestral polymorphism, additional data and analysis would be required.
Test runs with alternative prior distributions did not influence posterior estimates of this parameter.
Estimates also place a Balkan and Turkey clade divergence at Mismatch distribution analysis Figure 5 showed a unimodal distribution for the UK and CNE indicating a recent, rapid population expansion, which is consistent with an expansion at the end of the LGM when a land bridge facilitated dispersal of dormice to the UK.

Discussion Genetic Structure between UK and Continental Europe Here, we present the first evidence of genetic divergence between UK common dormouse populations and those in continental Europe. Our sequence analysis of Cytb, in the context of published data from continental Europe Mouton et al.
Further, it is shown that these UK lineages are most closely related to populations located in CNE Figure 2 and the within-population variation detected here is similar to that identified within regional subgroups in continental Europe by Mouton et al.
The nuclear gene bfibr, although monomorphic in the UK, shows genetic subdivision from continental Europe with a similar mutational difference to that of Cytb and D-loop studied here. Comparisons of genetic diversity for mitochondrial genes observed in the UK are comparable to that found in the genetic clades of continental Europe which may be a result of recent genetic divergence in the order of magnitude in thousands of years. Because the entire mitochondrial genome is inherited as a unit, sequencing more than one mitochondrial gene, as we have done, whilst offering more resolution on the history of the maternal lineage, still represents a single lineage and thus has some inherent limitations.

For this reason the addition of a nuclear gene in our analysis helps to confirm the identification of divergence between continental Europe and the UK. While there is evidence for reciprocal monophyly between continental European and UK dormice, further study of adaptive genetic variation in UK dormice is perhaps needed to inform management of the UK common dormouse as distinct.
Genetic Structure within the UK We describe the genetic structure of the common dormouse within the UK for the first time.
Here, we present evidence of regional genetic clustering of populations around the UK based on mtDNA variation clustering Figure 3. This regional variation is possibly explained by gross geographical features; the UK has several major rivers and uplands in the North, West, and South of the country which may be important geographical boundaries leading to the further genetic clustering seen in this study.
Although, the nuclear gene bfibr was monomorphic in our samples, the allelic sequence variant we report is unique to the UK. Mitochondrial DNA evolves at a much faster rate 5—10 fold and as such mtDNA is more suitable for resolving contemporary events and defining evolutionary significant units Wan et al. While the extent of regional genetic variation we describe is modest, it suggests the possibility of local adaptation and genetic differentiation which warrants further study at a finer geographical scale.
The phylogeographic structure we describe contrasts with that of previous small mammal studies.
Future assessment of the LCC technique in conjunction with other measures of stress, including corticosteroid measurements or behavioural observations may give increased confidence in the ability of this technique to identify patterns of stress and coping in free-living mammals.

This is primarily achieved by up-regulating key body functions, including cardiac-, respiratory- and brain-activity as well as energy mobilization at the expense of other processes such as growth, reproduction, immunity or the balance between oxygen radicals and the antioxidant system 29 — Therefore, the hazel dormouse is a compelling species to investigate the effects of the LGM on geographical expansion under a regime of climate change.
