The genetic integrity and evolutionary persistence of declining wildcat populations are threatened by crossbreeding with widespread free‐living domestic cats. Here we use allelic variation at 12 microsatellite loci to describe genetic variation in 336 cats sampled from nine European countries. Cats were identified as European wildcats (Felis silvestris silvestris), Sardinian wildcats (F. s. libyca) and domestic cats (F. s. catus), according to phenotypic traits, geographical locations and… 

Molecular analysis of hybridisation between wild and domestic cats (Felis silvestris) in Portugal: implications for conservation

The endangered European wildcat (Felis silvestris silvestris) is represented, today, by fragmented and declining populations whose genetic integrity is considered to be seriously threatened by

Genetic structure of wildcat (Felis silvestris) populations in Italy

Severe climatic changes during the Pleistocene shaped the distributions of temperate-adapted species. These species survived glaciations in classical southern refuges with more temperate climates, as

Hybridization versus conservation: are domestic cats threatening the genetic integrity of wildcats (Felis silvestris silvestris) in Iberian Peninsula?

The findings suggest that the true proportion of admixture can be higher than the value estimated in this study and that the improvement of genetic tools for hybrids detection is crucial for wildcat conservation.

Conservation genetics of European wildcat (Felis silvestris silvestris): a wide and integrating analysis protocol for admixture inferences and population structure

The use of highly polymorphic loci, Bayesian statistical inferences and landscape analyses tools are combined to investigate the origin of the geographic-genetic substructure of European wildcats in Italy and Europe and hypnotize the possibility that ancient introgressive events might have occurred.

Large-scale genetic census of an elusive carnivore, the European wildcat (Felis s. silvestris)

The analyses confirm a relatively continuous spatial presence of wildcats across large parts of the study area in contrast to previous analyses indicating a highly fragmented distribution, and suggest that wildcat conservation and management should take advantage of the higher than previously assumed dispersal potential of wild Cats may use wildlife corridors very efficiently.

Preserving genetic integrity in a hybridising world: are European Wildcats (Felis silvestris silvestris) in eastern France distinct from sympatric feral domestic cats?

It is demonstrated that a genetically distinct population of cats that possess the European Wildcat phenotype persists in north-eastern France, but that there is a low, yet real, risk of hybridisation with sympatric domestic cats.

The Genetic Integrity of the Ex Situ Population of the European Wildcat (Felis silvestris silvestris) Is Seriously Threatened by Introgression from Domestic Cats (Felis silvestris catus)

The results suggest that the high genetic diversity of the captive population of Felis s.

Regionally high rates of hybridization and introgression in German wildcat populations (Felis silvestris, Carnivora, Felidae)

Investigating population structure, evolutionary relationships and degree of hybridization with domestic cats found possible evolutionary reasons for the still traceable genetic integrity of the wildcat despite its long history of interbreeding are discussed.

Genetic analysis shows low levels of hybridization between African wildcats (Felis silvestris lybica) and domestic cats (F. s. catus) in South Africa

While African wildcat populations in South Africa generally appear to be genetically pure, with low levels of hybridization, genetic data do suggest that protected areas may play an important role in maintaining genetic purity by reducing the likelihood of contact with domestic cats.

Genetic identification of wild and domestic cats (Felis silvestris) and their hybrids using Bayesian clustering methods.

Admixture analyses suggest that wild and domestic cats in Italy are distinct, reproductively isolated gene pools and that introgression of domestic alleles into the wild-living population is very limited and geographically localized.

Genetic Variability and Biochemical Systematics of Domestic and Wild Cat Populations (Felis silvestris: Felidae)

Dendrograms indicate that the domestic cat belongs to the African wild cat lineage, which supports current hypotheses on cat domestication, and that the European and African wild cats diverged approximately 20,000 years ago.

Genetic diversity and introgression in the Scottish wildcat

It is argued that this is evidence that these cats do not have very recent domestic ancestry, but from the morphological data it is highly likely that this gene pool also contains a contribution from earlier introgression of domestic cat genes.

Microsatellite analysis reveals that domestic cat (Felis catus) and southern African wild cat (F. lybica) are genetically distinct

The data indicate that the level of genetic introgression is lower than previously thought, which enhances the conservation status of the African wild cat and demonstrates the need for the implementation of feral cat control in and around game reserves and rural areas.

Morphological and pelage characteristics of wild living cats in Scotland: implications for defining the ‘wildcat’

The paper highlights the complexity and difficulties for conventional taxonomy when used as a means for distinguishing between a wild type and its domesticated form where there is interbreeding and challenges the concept of the wildcat and the domestic cat as separate species.

Ecology and genetics of wild-living cats in the north-east of Scotland and the implications for the conservation of the wildcat

Traditional approaches for attempting to distinguish wild animals in the face of interbreeding with their domestic forms are neither accurate nor effective, and conservation should focus on mechanisms for dealing with groups of animals below the species level.

A genetic linkage map of microsatellites in the domestic cat (Felis catus).

A genetic linkage map of microsatellite loci in the feline genome has been constructed including 246 autosomal and 7 X-linked loci, which provides a valuable resource for mapping phenotypic variation in the species and relating it to gene maps of other mammals, including human.

Morphological discriminants of Scottish wildcats (Felis silvestris), domestic cats (F. catus) and their hybrids

It is suggested that the older wildcat populations were a relatively ‘pure’ form but more recent populations contain a significant hybrid component, and an alternative conclusion is that the “pure” form of wildcat is effectively extinct in Scotland.

Empirical evaluation of genetic clustering methods using multilocus genotypes from 20 chicken breeds.

It is suggested that in species for which population structure is of interest, databases of multilocus genotypes at highly variable markers should be compiled and these genotypes could be used as training samples for genetic cluster analysis and to facilitate assignments of individuals of unknown origin to populations.

Using an island model with sex-specific demographic parameters, it is found that random male dispersal is consistent with the population structure observed in the noctule, although other parameter combinations are also compatible with the data.
