“…By utilizing nuclear (i.e., microsatellite), mtDNA and Y chromosome loci, it was possible to test for both the frequency and direction of introgression between these species. As with the findings of an earlier study in which only nuclear loci were used (Lodé et al 2005), the analysis by Cabria et al (2011) detected low levels of introgression (ca. 1 %).…”

In this review, we posit the hypothesis that divergence-with-gene-flow or, using the terminology that has historical precedence, evolution-with-hybridization is not the exception as argued by the neo-Darwinian architects, but rather the rule. In particular, we will discuss briefly how the definition of species and the process of speciation that emerged from the Modern Synthesis limited greatly how evolutionary diversification was perceived to occur. This, in turn, resulted in only certain hypotheses and research directions being deemed legitimate for evolutionary biologists. Yet, we will also argue that in general, the assumptions that resulted in the definitions and concepts surrounding speciation were made much stronger by a dearth, rather than a wealth, of the data needed to test hypotheses. Specifically, these alternative hypotheses were divergence in allopatry versus divergence with at least some genetic exchange. We will point to the observation made by Anderson-the architect of studies of introgressive hybridization-that to test for contemporaneous or ancient gene flow between diverging/divergent lineages requires discrete markers. Thus, not until the advent of methods for analyzing the genetic constitution of individual organisms was it possible to test rigorously the alternate modes of divergence. To illustrate our hypotheses and conclusions, we will focus on mammalian lineages, including our own species. This focus reflects our desire to emphasize that not only prokaryotes and plants, but animals as well, reflect the process of reticulate evolution.

“…Although rare, hybridisation with the European mink Mustela lutreola (Linnaeus, 1761) seems to pose a major threat for mink populations that are more depleted locally than polecat populations (Lodé et al, 2005;Cabria et al, 2011). In Britain, current hybridisation with ferrets does not seem to be a cause for concern, but it was significant in the recent past during and subsequent to the polecat demographic decline of the 19th century and prevents the reliable identification of "pure polecats" solely based on morphological characteristics (Davison et al, 1999;Costa et al, 2013).…”

Ecology and conservation of the polecat Mustela putorius (Linnaeus, 1758) ABSTRACTIn Portugal, the current status of the European polecat Mustela putorius (Linnaeus, 1758) is Data Deficient but, although apparently widespread in the country, empirical evidence suggests a population decline. The present review summarises information from published studies and grey literature concerning the species' distribution, ecological requirements and the negative impacts of anthropogenic pressures. In southern Portugal, polecats seem to be strongly associated with riparian habitats and specialised in the consumption of lagomorphs. Main threats to the species in Portugal are habitat degradation due to agricultural intensification, decline of prey populations, direct persecution, and road mortality. Further research is urgently needed to accurately map the occurrence of the polecat and assess the current trend of its populations, so that conservation and management actions can be properly applied. Ongoing studies are expected to provide new insights into patterns of time and space use, genetic structure and putative hybridisation with domestic ferrets, and interspecific interactions with the other semi-aquatic carnivores of the Portuguese fauna, the otter Lutra lutra (Linnaeus, 1758) and the American mink Neovison vison (Schreber, 1777). Conservation actions should include the recovery and preservation of the habitats for polecats and their prey, promotion of non-intensive farming and restricted use of pesticides, surveillance of predator control activities, enforcement of mitigation measures in human-altered landscapes, and monitoring of hybridisation with ferrets. The implementation of these measures should increase polecat chances of persisting in Portuguese landscapes and, ultimately, would benefit the whole carnivore community. KEY WORDS:European polecat, ecology and conservation, literature review, Mustela putorius, Portugal. RESUMENLa información actual sobre el estado del turón Mustela putorius (Linnaeus, 1758) en Portugal es escasa; sin embargo, a pesar de que parece estar ampliamente distribuido por todo el país, evidencias empíricas parecen indicar un disminución de la población. La presente revisión es un compendio de toda la información disponible en artículos y literatura gris sobre su distribución, ecología y el impacto que la actividad humana ha ejercido sobre la especie. En el sur de Portugal, el turón parece estar fuertemente asociado a zonas ribereñas y haberse especializado en el consumo de lagomorfos. Las principales amenazas a esta especie en Portugal son la degradación de su hábitat debido a la intensificación de la agricultura, la disminución de las poblaciones de sus presas, la persecución directa de animales, y la muerte accidental en carreteras. Por lo tanto, es necesaria más investigación que permita determinar la incidencia y tendencias de las poblaciones de turón, con el fin de poder aplicar e implementar eficazmente diferentes programas de conservación y gestión. Se espera que los estudios en...

A b s t r a c tIntrogression of wild and domestic species is regarded as a promising way to improve genetic diversity in populations of farm animals. The aim of our study was to investigate the influence of introgression of the wild species (argali) on genetic diversity of interspecific hybrids with domestic sheep using STR and SNP markers. Samples included original parental forms: Romanov sheep (ROM, n = 35), representing the «domestic» form (Ovis aries), and argali (OAM, n = 10), characterizing the «wild» form (O. ammon polii), male hybrid F1, obtained by surgical insemination of Romanov ewe by argali sperm (F 1 , n = 1), and back crosses obtained by crossing Romanov ewes with hybrid F 1 ram (BC 1 , n = 38) and hybrid BC 1 rams (BC 2 , n = 14). The analysis of 11 STR loci (BLT001B, CSRD247, FCB20, CSAP36, MAF65, McM147, OarCP49, D5S2, HSC, BMS2213 and INRA23) was carried out on the ABI PRISM 3130xl genetic analyzer. For SNP genotyping we used Ovine SNP50K BeadChip. After quality control, 9 STR loci and 8591 SNPs were left for the analysis. Statistical calculations were performed in GenAIEx 6.5, PLINK v1.07, HP-Rare 1.1, GENETIX 4.05 and STRUCTURE 2.3.4. Regardless the type of DNA marker, ROM, compared with OAM, was characterized by a higher level of genetic diversity, assessed by observed heterozygosity (H o ) and allelic richness (Ar). Hybridization resulted in an increase in this parameter in the F 1 hybrid. In groups BC 1 and BC 2 , the H o values, calculated per STR and SNP, were higher than similar in the parental forms. In BC 1 and BC 2 groups the Ar values, estimated by SNP-markers, were reducing in comparison with F 1 and were intermediate in comparison with the same in the parental forms. The changes in the Ar values, based on STR data, had the character of a trend in groups BC 1 and BC 2 . Principal component analysis (PCA), performed by using SNP-markers, showed a more objective distribution pattern of the studied animals according to their origin in the coordinates space. In case of SNP data, PC1 was sufficient for clearly differentiation of groups OAM, ROM, F 1 and BC 1 + BC 2 . In summary, the first two components (PC1 and PC2) were responsible for 25.87 % of the SNP variability and for only 12.46 % of the STR variability. Principal component 3 (PC3), which was responsible for 6.16 % of SNP variability, made it possible to differentiate BC 1 and BC 2 groups, whereas at the application of STR these groups were localized as a common cluster. The results of STRUCTURE analysis showed that association of the investigated individuals into clusters, based on STR-profiles, did not match their origin, while the formation of clusters by SNP-markers was corresponded to the actual origin of animals. We found that both types of tested DNA markers were suitable for detecting changes in genetic diversity through hybrids generation. Nevertheless, a significant advantage of using multiple SNP-markers for the differentiation of hybrids from the parental forms was shown.
