Genomic insights into local adaptation in the Asiatic toad Bufo gargarizans, and its genomic offset to climate warming

Abstract

Clarifying the genomic signatures, genes, and traits underlying local adaptation of organisms to their environments is a major goal in evolutionary biology. Local adaptation can generate genetic differentiation and divergence among populations, which may lead to reduced gene flow and eventually speciation (Merilä et al., 2004;Savolainen et al., 2013). Local adaptation across a landscape can disrupt patterns of isolation-by-distance (IBD) and result in patterns of isolation-by-environment (IBE; Sexton et al., 2014;Wang & Bradburd, 2014). Isolation-by-resistance (IBR), a modification of IBD, predicts that patterns of genetic divergence are explained by geographic distances accounting for variation in the degree of resistance to dispersal that organisms experience through heterogeneous landscapes (MacDonald et al., 2020;McRae, 2006). Studies of patterns of IBE, IBR, and IBD have facilitated our understanding of local adaptation in various organisms, such as the swallowtail butterfly Papilio machaon dodi (MacDonald et al., 2020) and Anolis

Predicting species invasiveness with genomic data: is Genomic Offset related to establishment probability?

“…In recent years, GO approaches have been widely adopted in the field of conservation biology, being employed across a diverse array of taxa to estimate populations vulnerability to climate change to inform future management action (Ruegg et al ., 2018; Rhoné et al ., 2020; Morgan et al ., 2020; Zhang et al ., 2023a; Capblancq et al ., 2020a; Borrell et al ., 2020). These methods indeed allow accounting for population local adaptation within species, which is not achievable through conventional Species Distribution Modelling (SDM) methods that assume niche uniformity.…”
