| do ecological communities disperse across biogeographic barriers as a unit? | biogeographic barriers have long been implicated as drivers of biological diversification, but how these barriers influence co-occurring taxa can vary depending on factors intrinsic to the organism and in their relationships with other species. due to the interdependence among taxa, ecological communities present a compelling opportunity to explore how interactions among species may lead to a shared response to historical events. here we collect single nucleotide polymorphism data from five comm ... | 2017 | 28390087 |
