“…F ST is the main measure of genetic structure used in the literature and provides the greatest sample size for a meta-analysis. Although there is debate around the accuracy of F ST as a measure of genetic structure [24], it is the most widely used method and still considered to be a valid and accurate measure of genetic differentiation under a broad range of conditions [25][26][27]. A detailed list of search terms is given in the electronic supplementary material, but broadly, we looked for studies with the following words: ('genet*' OR 'genetic diff*' OR 'population structure' OR 'gene flow' OR 'dispersal' OR 'phylog*' OR 'landscape genetic*') AND ('Fst' OR 'Gst' OR 'D' OR 'F' OR 'F st' OR 'G st') AND ('amphibia*' OR 'frog*' OR 'salamand*' OR 'toad*').…”

“…We used the formula F ST /(1−F ST ) to linearize the F ST values, following Slatkin [42], and then used a logarithmic transformation. This process is equivalent to a logit transformation, which is commonly used and facilitates model convergence for this type of data [25][26][27]36,43]. Topographic distances were also log-transformed.…”

Predator–prey interactions have been suggested as drivers of diversity in different lineages, and the presence of anti-predator defences in some clades is linked to higher rates of diversification. Warning signals are some of the most widespread defences in the animal world, and there is evidence of higher diversification rates in aposematic lineages. The mechanisms behind such species richness, however, are still unclear. Here, we test whether lineages that use aposematism as anti-predator defence exhibit higher levels of genetic differentiation between populations, leading to increased opportunities for divergence. We collated from the literature more than 3000 pairwise genetic differentiation values across more than 700 populations from over 60 amphibian species. We find evidence that over short geographical distances, populations of species of aposematic lineages exhibit greater genetic divergence relative to species that are not aposematic. Our results support a scenario where the use of warning signals could restrict gene flow, and suggest that anti-predator defences could impact divergence between populations and potentially have effects at a macro-evolutionary scale.

“…In terms of landscape connectivity, physical barriers to movement and habitat quality throughout the landscape can both restrict dispersal (Manel & Holderegger, 2013 ). Negative effects of anthropogenically altered habitat on dispersal have been found for a range of species including small mammals (Ribeiro et al., 2021 ), birds (Björklund et al., 2010 ), bees (Jha & Kremen, 2013 ) and butterflies (Crawford et al., 2011 ; Takami et al., 2004 ). This may be due to higher mortality for animals that travel farther in between habitat fragments (Bonelli et al., 2013 ; Lucas et al., 1994 ; Mennechez et al., 2003 ).…”

Effects of landscape, resource use, and body size on genetic structure in bee populations

Quantifying genetic structure and levels of genetic variation are fundamentally important to predicting the ability of populations to persist in human‐altered landscapes and adapt to future environmental changes. Genetic structure reflects the dispersal of individuals over generations, which can be mediated by species‐level traits or environmental factors. Dispersal distances are commonly positively associated with body size and negatively associated with the amount of degraded habitat between sites, motivating the investigation of these potential drivers of dispersal concomitantly. We quantified genetic structure and genetic variability within populations of seven bee species from the genus Euglossa across fragmented landscapes. We genotyped bees at SNP loci and tested the following predictions: (1) deforested areas restrict gene flow; (2) larger species have lower genetic structure; (3) species with greater resource specialization have higher genetic structure; and (4) sites surrounded by more intact habitat have higher genetic diversity. Contrasting with previous work on bees, we found no associations between body size and genetic structure. Genetic structure was higher for species with greater resource specialization, and the amount of intact habitat between or surrounding sites was positively associated with parameters reflecting gene flow and genetic diversity. These results challenge the dominant paradigm that individuals of larger species disperse farther, and they suggest that landscape and resource requirements are important factors mediating dispersal.
