Preferred citation for this article: Lin J., 2024, The interplay between bird migration behavior and genetic diversity, Genomics and Applied Biology, 15(1): 1-7 (doi: 10.5376/gab.2024.15.0001) Abstract Avian migration is a significant phenomenon in biodiversity, and genetic diversity during migration is crucial for the adaptability and survival of species. This review begins by introducing the diversity of avian migration behavior and the pivotal role of genetic diversity. It then delves into analyzing the impact of climate change on avian migration, particularly focusing on the influence of rising temperatures on migration patterns and habitats. The review explores the potential effects of these changes on the genetic diversity of birds. It also discusses genetic adaptation and changes, revealing the survival strategies adopted by birds in response to climate change. Furthermore, it examines the response of genetic diversity in avian migration, including its relationship with adaptability, gene flow, migration paths, and genomic stability. These analyses are crucial for better understanding the dynamic changes in genetic diversity during avian migration, leading to the development of more effective conservation policies and ecosystem management. Through in-depth exploration, we can better protect and preserve avian migration, ensuring its continued prosperity in the face of challenges posed by climate change. Keywords Bird migration; Genetic diversity; Climate change; Adaptability; Ecosystem management The relationship between bird migration behavior and genetic diversity constitutes a stunning biological landscape, revealing a magical and ancient tradition in nature. The miraculous behavior not only demonstrates the wisdom of bird survival, but also highlights the perfection of the natural ecosystem. However, as global climate change becomes increasingly frequent and significant, bird migration faces unprecedented challenges. In recent decades, temperatures have continued to rise and extreme weather events have occurred frequently, which have had a profound impact on the migration of birds. The rise in temperature not only changes the seasonal climate pattern, but also directly affects the breeding, migration time, location, and route selection of birds. These changes are directly related to the behavioral habits, habitat selection, and resource allocation of birds, affecting the genetic diversity and genetic structure of the entire bird population (Tamario et al., 2019). Genetic diversity plays a crucial role in bird migration. It is the foundation for bird populations to adapt to environmental changes and determines their ability to adapt to different environmental pressures (Berthold, 2002). However, climate change may have a negative impact on genetic diversity, making migratory populations more susceptible to genetic bottlenecks and drift, thereby reducing their adaptability and survival ability (Morganti, 2015). This study aims to comprehensively explore the impact of climate change on genetic diversity in bird migration. By conducting in-depth analysis of the relationship between gene diversity and adaptability, gene flow and migration pathways, as well as genome stability and environmental changes, this study will examine the biological responses of bird populations to high temperature and climate change. Exploring the relationship between bird migration and genetic diversity in depth will also provide a more comprehensive understanding and insight for the protection and sustainable management of global ecosystems. Exploring the impact of climate change on bird migration is an inevitable choice for in-depth thinking and research on this magnificent phenomenon in nature. Only through continuous deepening of understanding can people better protect and maintain this rich and diverse Earth ecosystem.
