Genetic Diversity and Hybridization in Wildcat Populations
Summary
Wildcat populations across Europe and beyond exhibit a complex interplay of genetic variation and hybridisation with domestic congeners. Natural genetic diversity within isolated wildcat lineages reflects historical refugial patterns, climatic shifts and long‐term demographic stability, but contemporary pressures have reshaped this landscape. Fragmentation of habitats by urban expansion and changes in land use has reduced connectivity, leading to small, vulnerable populations in some regions. At the same time, free-ranging domestic cats have established widespread contact with wildcats, creating hybrid swarms that blur taxonomic boundaries and threaten the genetic integrity of native populations. Genome-wide surveys have revealed uneven patterns of domestic gene flow, with certain genomic regions such as the major histocompatibility complex showing disproportionately high introgression, suggesting adaptive benefits in disease resistance. Conservation strategies now hinge upon accurate discrimination between pure and admixed individuals, long-term monitoring of gene flow and the restoration of ecological corridors. By integrating molecular tools with landscape modelling and demographic data, this field has advanced from simple assessments of hybrid presence to nuanced understanding of the evolutionary and conservation consequences of hybridisation in a human-dominated world.

Genetic Diversity and Hybridization in Wildcat Populations publication trend
The graph below shows the total number of articles in genetic diversity and hybridization in wildcat populations across all publications each year (not limited to Nature Index journals).
Technical terms
Genetic diversity: Measure of variation in DNA sequences within and among populations, reflecting their evolutionary resilience.
Hybridization: Interbreeding between distinct species or populations that results in mixed ancestry.
Introgression: Stable incorporation of genes from one population or species into another through repeated backcrossing.
Single nucleotide polymorphism (SNP): Single-base variation in the genome used as a marker for population studies.
Genome-wide analysis: Comprehensive survey of genetic variation across an organism’s entire genome to infer structure, history and selection.
Major histocompatibility complex (MHC): A gene region central to immune response, often under strong selection and subject to introgression.

About these summaries
This Nature Research Intelligence Topic summary is created with the cited references and a large language model. We take care to ground generated text with facts, and have systems in place to gain human feedback on the overall quality of the process in line with our AI principles. We strive to create accurate and useful summaries for people unfamiliar with the research topic and that supports this goal. These pages are a beta release and will be updated as we learn how best to help people gain value from a research topic summary.
