New study shows a genetic link between feeding behavior and animal dispersal
Date:2/24/2014

to studies tracing the chemical signatures and dental records of early humans. While the chemical isotopes and tooth wear of most specimens indicated they foraged and resided locally, a few specimens carried isotopes from very different habitats suggesting they may have immigrated from far away. Whether the foraging gene plays a role in their dispersal tendencies remains unknown.

The ability to predict differences in dispersal tendencies could also influence how we build and maintain natural corridors for threatened species or how we stop the spread of invasive species like the round goby, emerald ash borer, or the Asian longhorned beetle, adds Fitzpatrick. "We are at an exciting critical juncture where work on genes and genomes are merging with a wealth of work on behavioural personalities and animal movement ecology," he says.

The research is currently available online and will be published in the upcoming edition of Ecology Letters.
