Next-generation sequencing (NGS) and genotyping-by-sequencing (GBS) have enabled researchers to sample genomes more densely, providing deeper insights into genetic variation and evolutionary processes. These technologies have facilitated the generation of high-quality genome assemblies for various felid species, such as the leopard, which has allowed for comparative genomic analyses across different dietary specializations (Smith et al., 2017). Future research should focus on leveraging these technologies to sequence whole genomes of larger populations, which, although currently expensive, will become more feasible as costs decrease and computational methods improve. Additionally, the development of more sophisticated bioinformatic tools will be crucial for handling the vast amounts of data generated by these technologies (Vonholdt et al., 2018). 9.2 Integrating genomics with ecological data Integrating genomic data with ecological and behavioral data is essential for a comprehensive understanding of felid conservation (Kim et al., 2017). Long-term field studies have provided valuable insights into the social systems, ecophysiology, and ecology of carnivores, which are critical for interpreting genomic data in a meaningful context. For instance, understanding the genetic basis of traits such as reproductive suppression and dispersal can inform conservation strategies aimed at maintaining genetic diversity and population viability. Moreover, combining genomic data with ecological information can help identify adaptive traits that are crucial for survival in changing environments (Narum et al., 2013). This integrative approach will enable more effective conservation management by providing a holistic view of the factors influencing felid populations (Primmer, 2009). 9.3 Long-term conservation goals Long-term conservation goals for felids should prioritize maintaining genetic diversity and evolutionary potential. Genomic studies have revealed significant genetic erosion in endangered species like the Iberian lynx, highlighting the need for strategies that mitigate the effects of demographic bottlenecks and inbreeding. Conservation efforts should focus on preserving genetic diversity by facilitating gene flow between isolated populations and protecting habitats that support large, viable populations. Additionally, understanding the genetic architecture of adaptive traits can inform breeding programs and reintroduction efforts aimed at enhancing the resilience of felid populations to environmental changes (Harrisson et al., 2014). Ultimately, the integration of genomics into conservation planning will be essential for ensuring the long-term survival of felid species in the face of ongoing threats such as habitat loss and climate change (Azizan and Paradis, 2021). 10 Concluding Remarks The comparative genomic studies of felids have provided significant insights into the evolutionary adaptations and conservation challenges faced by these carnivores. Key findings include the identification of shared evolutionary adaptations in genes associated with diet, muscle strength, and agility, which are crucial for hunting and meat consumption. Additionally, felids exhibit low levels of genetic diversity, likely due to their strict dietary requirements and reduced population sizes, making them vulnerable to environmental changes and human activities . The genomic erosion observed in endangered species like the Iberian lynx further highlights the critical conservation status of these animals. Studies have also revealed the importance of gut microbiomes in adapting to high purine and fat diets, which is a characteristic feature of carnivorous felids. Genomic research plays a pivotal role in the conservation of felids by providing detailed insights into their genetic diversity, population structure, and evolutionary history. The identification of genetic markers and adaptive traits can inform conservation strategies aimed at enhancing genetic diversity and resilience in wild populations. For instance, understanding the genetic consequences of habitat fragmentation and human activities can help in planning wildlife corridors and other conservation measures. Moreover, the development of high-quality reference genomes and cross-species genome alignments can aid in the discovery of adaptive and deleterious alleles, which are essential for managing genetic health and disease in felid populations.
