Genetic adaptation refers to the changes in the genetic makeup of populations that enhance their survival and reproduction in changing environments. By studying these adaptations, conservationists can identify the genetic traits that are beneficial for survival under specific environmental conditions. For instance, research has shown that genetic correlations can significantly constrain the rate of adaptation in avian species, which could impact their ability to persist in rapidly changing environments (Teplitsky et al., 2014). Additionally, the identification of candidate genes responsible for adaptation to new ecological niches, such as nocturnality, can provide insights into the mechanisms of adaptation and inform targeted conservation efforts (Charmantier et al., 2016). 8.2 The role of genetic diversity in avian species’ long-term survival Genetic diversity is a key factor in the long-term survival of avian species. High levels of genetic diversity increase the likelihood that some individuals within a population possess genetic variants that confer resistance to environmental changes, diseases, or other threats. Studies have shown that populations with higher genetic diversity are better equipped to adapt to new environments and changing conditions (Yin et al., 2021). For example, the genomic diversity in birds has been linked to habitat availability and life-history traits, which are critical for their conservation (Brüniche‐Olsen et al., 2021). Moreover, standing genetic variation has been identified as a predominant source for adaptation, highlighting the importance of maintaining genetic diversity within populations (Lai et al., 2019). 9 Concluding Remarks This study has synthesized current knowledge on the genetic adaptation of avian species to rapid environmental changes, highlighting several key findings. Natural selection, genetic mutations, gene flow, and epigenetic mechanisms play crucial roles in facilitating genetic adaptation in birds, allowing them to survive and thrive in increasingly volatile environments. Climate change, habitat destruction, pollution, and invasive species introduce significant environmental stressors that drive these adaptive processes. Moreover, the role of migration has been underscored as a critical factor in shaping genetic diversity and adaptation, with migratory behaviors influencing gene flow and leading to rapid evolutionary changes. The implications for future research are substantial. As environmental changes accelerate, there is an urgent need to deepen our understanding of the genetic mechanisms that underpin avian adaptation. Studies should focus on identifying the specific genes and genetic pathways involved in adaptation to different environmental stressors, as well as the interplay between phenotypic plasticity and genetic adaptation. Additionally, there is a need to explore the long-term effects of climate change on avian species, particularly in relation to their adaptive capacity and the potential for evolutionary rescue. Preserving avian genetic diversity is of paramount importance in the face of rapid environmental changes. High genetic diversity within populations enhances their ability to adapt to new conditions and ensures the long-term survival of species. Conservation strategies should prioritize the protection of habitats and the maintenance of landscape connectivity to facilitate gene flow and the spread of adaptive traits. Ultimately, safeguarding avian genetic diversity is essential not only for the resilience of bird populations but also for the broader health of ecosystems in which they play a critical role.
