“…Several studies have investigated population genetic structure in wild red fox populations, though only a handful of studies revealed signs of a strong genetic structuring (e.g., References [54,55]). This is most likely due to the red fox's ability to traverse long distances, and thereby exhibit a high degree of gene flow [7].…”

Knowledge about the dispersal and gene flow patterns in wild animals are important for our understanding of population ecology and the connectedness of populations. It is also important for management relating to disease control and the transmission of new and emerging diseases. Our study aimed to evaluate the genetic structuring among comparative samples of red foxes in a small part of Scandinavia and to estimate the gene flow and potential directionality in the movements of foxes using an optimized set of microsatellite markers. We compared genetic samples of red foxes (Vulpes vulpes) from two areas in Sweden and two areas in Norway, including red fox samples from areas where the occurrence of the cyclophyllic tapeworm Echinococcus multilocularis has been documented, and areas without known occurrence of the parasite. Our results show a high level of gene flow over considerable distances and substantiates migration from areas affected with E. multilocularis into Norway where the parasite is not yet detected. The results allow us to better understand the gene flow and directionality in the movement patterns of red foxes, which is important for wildlife management authorities regarding the spread of E. multilocularis.

“…This distinct clustering was allocated to the presence of two putatively different colonization waves during quaternary glaciation. Cohen et al [55] found evidence of four population genetic clusters in Israeli red foxes using microsatellite markers. Here, the genetic structuring was attributed to anthropogenic limits to connectivity.…”

“…Previous studies have successfully used microsatellite primers developed from the domestic dog genome to describe genetic diversity and structure among red fox populations (Wandeler et al 2003 ; Oishi et al 2010 ; Magory Cohen et al 2012 ). Here, we report the first application of microsatellite loci from a domesticated red fox genome (Yan, unpublished) to natural fox populations.…”

“…The highest level of differentiation was found between the urban populations either side of a river, but there was evidence of gene flow between urban and rural populations. Several studies using microsatellites and mitochondrial DNA (Oishi et al 2010 ; Magory Cohen et al 2012 ; Galov et al 2014 ) described the genetic structure among red fox populations over wide geographical areas and revealed a pattern of weak genetic structure, highlighting the adaptability and dispersal potential of red foxes.…”

The influence of habitat structure on genetic differentiation in red fox populations in north-eastern Poland

et al. 2014

The red fox (Vulpes vulpes) has the widest global distribution among terrestrial carnivore species, occupying most of the Northern Hemisphere in its native range. Because it carries diseases that can be transmitted to humans and domestic animals, it is important to gather information about their movements and dispersal in their natural habitat but it is difficult to do so at a broad scale with trapping and telemetry. In this study, we have described the genetic diversity and structure of red fox populations in six areas of north-eastern Poland, based on samples collected from 2002–2003. We tested 22 microsatellite loci isolated from the dog and the red fox genome to select a panel of nine polymorphic loci suitable for this study. Genetic differentiation between the six studied populations was low to moderate and analysis in Structure revealed a panmictic population in the region. Spatial autocorrelation among all individuals showed a pattern of decreasing relatedness with increasing distance and this was not significantly negative until 93 km, indicating a pattern of isolation-by-distance over a large area. However, there was no correlation between genetic distance and either Euclidean distance or least-cost path distance at the population level. There was a significant relationship between genetic distance and the proportion of large forests and water along the Euclidean distances. These types of habitats may influence dispersal paths taken by red foxes, which is useful information in terms of wildlife disease management.Electronic supplementary materialThe online version of this article (doi:10.1007/s13364-014-0180-2) contains supplementary material, which is available to authorized users.

“…Paternal ancestry of hybrids may be revealed by species-specific Y chromosome markers developed to discriminate between golden jackal and domestic dog males, based on an insertion found in a dog Zfy intron, but not in golden jackal [ 20 ]. In addition, putatively neutral biparental markers such as microsatellite loci (STR), originally developed for the domestic dog, can efficiently cross-amplify and identify golden jackal genotypes [ 19 , 21 ], thus providing estimates of the proportion of neutral admixture inherited from the mixing parental populations (e.g. [ 5 , 17 , 22 ]).…”

First evidence of hybridization between golden jackal (Canis aureus) and domestic dog (Canis familiaris) as revealed by genetic markers

et al. 2015

Interspecific hybridization is relatively frequent in nature and numerous cases of hybridization between wild canids and domestic dogs have been recorded. However, hybrids between golden jackals (Canis aureus) and other canids have not been described before. In this study, we combined the use of biparental (15 autosomal microsatellites and three major histocompatibility complex (MHC) loci) and uniparental (mtDNA control region and a Y-linked Zfy intron) genetic markers to assess the admixed origin of three wild-living canids showing anomalous phenotypic traits. Results indicated that these canids were hybrids between golden jackals and domestic dogs. One of them was a backcross to jackal and another one was a backcross to dog, confirming that golden jackal–domestic dog hybrids are fertile. The uniparental markers showed that the direction of hybridization, namely females of the wild species hybridizing with male domestic dogs, was common to most cases of canid hybridization. A melanistic 3bp-deletion at the K locus (β-defensin CDB103 gene), that was absent in reference golden jackal samples, but was found in a backcross to jackal with anomalous black coat, suggested its introgression from dogs via hybridization. Moreover, we demonstrated that MHC sequences, although rarely used as markers of hybridization, can be also suitable for the identification of hybrids, as long as haplotypes are exclusive for the parental species.
