loss of genetic diversity and increased embryonic mortality in non-native lizard populations.	many populations are small and isolated with limited genetic variation and high risk of mating with close relatives. inbreeding depression is suspected to contribute to extinction of wild populations, but the historical and demographic factors that contribute to reduced population viability are often difficult to tease apart. replicated introduction events in non-native species can offer insights into this problem because they allow us to study how genetic variation and inbreeding depression are ...	2016	27393416
adaptive responses to cool climate promotes persistence of a non-native lizard.	successful establishment and range expansion of non-native species often require rapid accommodation of novel environments. here, we use common-garden experiments to demonstrate parallel adaptive evolutionary response to a cool climate in populations of wall lizards (podarcis muralis) introduced from southern europe into england. low soil temperatures in the introduced range delay hatching, which generates directional selection for a shorter incubation period. non-native lizards from two separat ...	2015	25694617
widespread primary, but geographically restricted secondary, human introductions of wall lizards, podarcis muralis.	establishing the introduction pathways of alien species is a fundamental task in invasion biology. the common wall lizard, podarcis muralis, has been widely introduced outside of its native range in both europe and north america, primarily through escaped pets or deliberate release of animals from captive or wild populations. here, we use bayesian clustering, approximate bayesian computation (abc) methods and network analyses to reconstruct the origin and colonization history of 23 non-native po ...	2015	25891955
