“…Prior to genetic analyses, all wildcats except those from Hainich had been determined as such on the basis of coat colour patterns, intestine length, and skull volume (cf. Schauenberg 1969Schauenberg , 1977. Moreover, a mixed sample of stray domestic cats and pet cats from Vienna (n=22) was available for allozyme electrophoresis only.…”

Genetic diversity and integrity of German wildcat (Felis silvestris) populations as revealed by microsatellites, allozymes, and mitochondrial DNA sequences

As a consequence of persecution and habitat fragmentation, wildcats (Felis silvestris silvestris) in Western Europe have experienced a severe reduction in population numbers and sizes. The remaining wildcat populations are considered to be endangered by losses of genetic variability and by hybridisation with free-ranging domestic cats. To investigate genetic diversity within and among wild and domestic cat populations in Germany and to estimate the extent of gene flow between both forms, we analysed a total of 266 individuals. PCR-amplification and sequencing of 322 base pairs of a highly variable part of the mitochondrial control region (HV1) of 244 specimens resulted in 41 haplotypes with 31 polymorphic sites. Additionally, eight microsatellite loci were examined for those 244 cats. Moreover, a total of 46 wildcats and 22 domestic cats could be genotyped for 13 polymorphic out of 31 enzyme loci. Genetic variability in both groups was generally high. Variability in domestic cat populations was higher than in wildcat populations. Almost no differentiation between domestic cat populations could be found (F ST for microsatellites=3%). In contrast, wildcat populations differed significantly from one another (F ST for microsatellites=9.55%) Within the smaller wildcat populations, a reduction of genetic diversity was detectable with regard to the nuclear DNA. Wildcat and domestic cat mitochondrial haplotypes were separated, suggesting a very low level of maternal gene flow between both forms. In microsatellites and to a somewhat lesser extent in allozymes, wildcats and domestic cats showed distinct differentiation, suggesting an only low extent of past hybridisation in certain populations. The microsatellite data set indicated a significantly reduced effective population size (bottleneck) in the recent past for one German wildcat population.

Populations of Felis silvestris, the European, Asian and African wildcats, and the domestic cat, are characterized by a variable, genetically controlled, coat-colour and markings system. Samples of the three Italian cats, the European, the Sardinian (belonging to the African group) and the domestic striped tabby were studied for composition and occurrence of coat-colour and markings patterns, as well as for their association with craniometric and splanchnometric categories. Intergroup differences in the coat-colour and markings system were consistent with known metric differences. It was thus possible to distinguish, objectively, the three cats from each other by means of coat patterns, even more clearly than with metric procedures. Distances between taxa, calculated through the relative frequencies of the coat patterns, were fully consistent with those measured from allele frequencies for polymorphic loci. This confirmed the polytypical species status of Felis silvestris.

“…Schauenberg (1969Schauenberg ( , 1977 reported that European wildcats have a shorter intestinal length and that wildcats have a cranial index (greatest length of the skull divided by cranial volume) of less than 2.75, whereas domestic cats have a cranial index greater than 2.75. The Scottish wildcat was reported to be distinguishable from the domestic cat and their hybrids based on its larger, more robust skull, especially the cranium, mandibles and occipital region (French, Corbett & Easterbee, 1988).…”

The natural morphological variation in the wildcat, Felis silvestris, and morphological changes possibly caused by introgressive hybridisation with the domestic cat, F. catus, were examined, based on up to 39 variables concerning cranial morphology. The samples of wild-living cats originated from Scotland and southern Africa and consisted of both classical wildcat and other pelage types. Principal component and cluster analyses suggested that introgressive hybridisation occurred in both areas, with the consequence that the characteristics of local wildcat populations had been altered in terms of the frequencies of occurrence of certain characters, especially those concerning cranial capacity. In both regions the clustering patterns of wild-living cats can be interpreted as containing four main groups. One of these consisted mainly of 'non-wildcats' and groups furthest from the 'non-wild' cluster consisted of the highest proportion of 'wildcats' (c. 80%). We propose that where a population is heavily introgressed, the only feasible way to define a wildcat is on the basis of inter-correlated features and conservationists must take a population-based approach to assess the extent of introgression. This approach may provide an operational standard for assessing the impact of hybridisation between wildcats and domestic cats throughout the species' range; it suggests that the Scottish wildcats may be critically endangered.
