Effects of natural and anthropogenic features on functional connectivity of anurans: a review of landscape genetics studies in temperate, subtropical and tropical species

Abstract: Habitat loss, overexploitation, the presence of invasive species, climate change and the proliferation of diseases continue to put at risk anuran species that represent 90% of all amphibians. Biphasic life cycle, habitat specialization to oviposit and forage, low dispersal abilities, and permeable skin make anurans particularly susceptible to the effect of landscape composition and configuration on their capacity to move through the landscape (connectivity). Limited connectivity can result in reduced gene flow… Show more

“…In the case of pool‐breeding amphibians, genetic connectivity implies that movement between breeding pools and breeding among individuals from different pools is sufficient to maintain genetic diversity (Frei et al 2016, Wang and Shaffer 2017, Covarrubias et al 2021). Demographic connectivity similarly implies that enough individuals move between pools to promote persistence of metapopulations, either through recolonization of breeding pools that become extirpated or through dispersal of individuals from source populations to rescue sink populations from extirpation (Semlitsch 2008, Muths et al 2018, Bailey and Muths 2019).…”

“…In our study, at the landscape scale there was a very low proportion cover of urban land within a 500-m radius of waterbodies (mean 0.018, SD 0.051) with few obvious artificial barriers to amphibian dispersal, although the main river channel comprised a significant natural barrier (see Covarrubias et al, 2021). There was a high proportion of forest cover surrounding waterbodies (mean 0.735, SD 0.247) which is generally favourable for amphibian movement (Joly, 2019).…”

“…Unexpectedly, crop fields were not assigned a very high cost to newt movement in our study. Crop fields have often been found to correlate negatively with landscape connectivity in amphibians (Covarrubias et al., 2021 ) but see Frei et al. ( 2016 ) and Goldberg and Waits ( 2010 ).…”
