For instance, landscape genomics can reveal how genetic variations are associated with specific environmental gradients, which can inform the selection of sites for restoration efforts (Feng and Du, 2022). Additionally, understanding the genetic structure of Gammarus populations can help identify suitable donor populations for conservation translocations, ensuring that genetic diversity is maintained and that translocated populations are well-adapted to their new environments. 7.3 Predicting future Gammarus adaptation under climate change Predicting howGammarus populations will adapt to climate change involves understanding the genetic basis of their responses to environmental changes. Genomic data can help model the potential for local adaptation and identify regions where populations may be at risk due to climate change (Fitzpatrick and Keller, 2015; Chen et al., 2021). By mapping the geographic distribution of genetic variations, researchers can predict areas where Gammarus populations might face challenges in adapting to future climates, allowing for proactive conservation measures (Rodríguez-Correa et al., 2018). 7.4 Policy recommendations for freshwater and estuarine conservation Policy recommendations for the conservation of freshwater and estuarine ecosystems should incorporate genomic data to enhance the effectiveness of conservation strategies. This includes using genomic insights to inform habitat restoration, conservation translocations, and the management of genetic diversity within populations (Carlini and Fong, 2017). Policymakers should also consider the potential impacts of climate change on genetic diversity and adaptation, ensuring that conservation efforts are resilient to future environmental changes (Weiss and Leese, 2016).
