By integrating genomic data with ecological insights, researchers can uncover the genetic basis of adaptations to specific ecological niches and the evolutionary processes shaping these adaptations. For example, forest ecosystems provide crucial services such as carbon sequestration and biodiversity support. Genomic studies have highlighted the genetic diversity and local adaptations of tree species, which are essential for maintaining forest health and productivity in the face of climate change and other environmental stressors (Isabel et al., 2019). The interplay between tree genomes and their ecosystems is complex, involving gene-environment interactions that influence traits like drought tolerance, disease resistance, and phenological changes. Understanding these interactions helps in predicting how tree populations will respond to environmental changes, guiding conservation and management practices aimed at preserving biodiversity and ecosystem function (Matthews et al., 2018). 8.2 Role of genomic information in understanding ecological networks Genomic information is crucial for unraveling the complexities of ecological networks, which comprise the interactions between different species within an ecosystem. These interactions include mutualistic relationships, predator-prey dynamics, and competition, all of which can be influenced by genetic factors. For instance, genotypic variations in foundation tree species like Populus angustifolia can shape the structure of arthropod communities associated with these trees. This network structure can have significant implications for community dynamics and evolutionary processes (Lau et al., 2015). Genomic tools, such as DNA metabarcoding and landscape genomics, provide detailed insights into the genetic diversity and connectivity of species populations, helping to map and understand these intricate ecological networks. By studying how genetic variation affects species interactions and ecosystem functions, researchers can develop strategies to enhance ecosystem resilience and stability (Breed et al., 2019). 8.3 Future prospects for eco-genomic research in forest management The future of eco-genomic research holds great promise for advancing forest management and conservation practices. High-throughput sequencing technologies and bioinformatics tools are enabling more comprehensive and accurate assessments of genetic diversity, adaptive potential, and the impacts of environmental changes on tree populations. Emerging techniques such as CRISPR and genome editing offer new possibilities for enhancing desirable traits in trees, such as pest resistance and climate adaptability (Plomion et al., 2016). Integrating genomic data with ecological models can improve predictions of tree responses to environmental stressors and guide the development of adaptive management strategies. For instance, predictive genomic approaches can identify genetic markers associated with climate resilience, informing the selection and breeding of tree species that can thrive under future climate scenarios (Cortés et al., 2020). Additionally, genomic insights can help in the restoration of degraded ecosystems by ensuring the use of genetically diverse and locally adapted plant materials, thereby enhancing the success and sustainability of restoration efforts (Cordier et al., 2020). As eco-genomic research continues to evolve, it will play a crucial role in promoting sustainable forest management and conservation in the face of global environmental challenges. 9 Future Research Directions in Tree Genomics 9.1 Unexplored areas and emerging fields in tree genomics The field of tree genomics has made significant strides, yet many areas remain unexplored, offering exciting opportunities for future research. One emerging field is the study of tree epigenomics, which involves understanding how epigenetic modifications influence gene expression and phenotypic traits in trees. Epigenetic changes can play crucial roles in tree adaptation to environmental stressors, yet this area has received limited attention (Plomion et al., 2016). Another promising direction is the application of pangenomics, which involves analyzing the full complement of genes in a species, including core and accessory genes. This approach can
