There is a lot of undescribed diversity out there, and we need to know about the organisms on earth in order to appreciate and conserve them. This research is a first for the Marsico lab, but hopefully is opening the door to other new species discoveries.

Phylogeographic evidence for a Florida panhandle-peninsula discontinuity in the distribution of Melitara prodenialis Walker (Lepidoptera: Pyralidae), a native cactus-boring moth. Insect Conservation and Biodiversity. PDF reprint available by request. In this manuscript, my coauthors and I demonstrate that there is a biogeographic discontinuity along the Suwannee River in the Florida portion of the native range of the cactus-boring moth M. prodenialis. This work adds an insect example to the well-documented similar biogeographic discontinuities in Florida. We show that there are environmental differences between Florida panhandle and peninsula regions, and that these differences existed at the last interglacial, as well. Changes in host plant abundance and distribution and coastline in Florida may have contributed to the isolated insect populations observed.

Marsico, T. D., L. E. Wallace, G. N. Ervin, C. P. Brooks, J. E. McClure, and M. E. Welch. 2011. Geographic patterns of genetic diversity from the native range of Cactoblastis cactorum (Berg) support the documented history of invasion and multiple introductions for invasive populations. Biological Invasions 13: 857-868. PDF. In this publication my coauthors and I demonstrate that the invasive insect pest, Cactoblastis cactorum, has high levels of geographically partitioned genetic diversity in its native range relative to its invasive range in North America. We show that the only genetic diversity within the invaded range is also from the documented original biological control collection site in Entre Rios, Argentina. Still, it appears that there have been multiple introductions into North America, likely from the neighboring Caribbean. There is no evidence that the success of C. cactorum invasion in North America is due to the recombination of geographically-disparate genotypes from the native range, as has been suggested for the invasion success of some species.

Underutilized resources for studying the evolution of invasive species during their introduction, establishment, and lag phases. Evolutionary Applications 3: 203-219. PDF. This manuscript is the outcome of a collaboration that began at a conference on the role of evolution in species invasions. I am proud of this work, as I was able to lead this diverse group of graduate students, post-docs, and senior scientists to produce this meaningful contribution. In this paper, my coauthors and I put forth the idea that natural history specimens, biological control release and follow-up records, and horticultural import records can be more effectively used to determine the role of evolution in the success of species invasions.
