Join the journey of some Cuban lizards to find out how they created a revolution in the world of invasion biology. For years, invasive species have created a headache for everyday communities and research biologists alike. Despite experiencing a typical evolutionary bottleneck during introduction to a new location, invasive species defy the biological odds and show survival, success and growth in these environments. Until 2004, very little was known about how this was happening. Research by Kolbe et al. (2004) used a model species – the Brown Anole – to determine how invasive species beat the evolutionary bottleneck. Through phylogenetic analysis of native Cuban and introduced United States populations of these lizards, it was observed that the invasive groups not only survived, but actually became more diverse in their new environment. When multiple populations exist within a native environment, they are often geographically isolated and have high between-population diversity due to a lack of gene flow. However, previously isolated populations can become mixed in new environments, allowing them to increase within-population diversity, a process facilitated through multiple introductions of the species over time. With the Cuban lizards, the increased mixture of genetic material between distinct haplotypes provided an understanding of the genetic basis of how invasive species not only survive, but become stronger, in their new environments. The findings of this research have large-scale implications in the world of invasion biology and provides a model for other invasive species’ success. This has allowed a more detailed understanding of invasive species and how biologists can work to control the spread and success of introduced species to lessen damages to native environments and economy.
