Richard Dawkins shows how the relatively young island chain of Hawaii acts as a nursery of evolution as it moves over a volcanic hotspot in the Pacific Ocean, generating new islands. He shows how Drosophila flies have diverged on the different islands, driven by sexual selection.

This exhibit has now been replicated in six museums around the country. While visiting we filmed a collection of short unrehearsed and unscripted videos—just inspired by the “Explore Evolution” exhibit.

For class we were to use a scientific database to come up with a scientific research question. Unfortunately, good biological databases lacking at this time. As for as I am aware, there is nothing even close to the level of the geology database, GeoMapApp, we used in class. This lack of biological databases is a problem that my adviser is currently working to solve and is one of the projects I am trying to help with. It's called The Biofinity Project. It will be a repository of biodiversity data and be an invaluable tool to biodiversity research. However, it is not yet available (hopefully within the next couple of months it will be).

Back to the task at hand. The database I did use is called Global Biodiversity Information Facility (GBIF), but it is far from complete in my area of interest. I looked up the distribution data for the beetle Cyclocephala amazona to be suprised by the results. According to my information on C. amazona it occurs from Costa Rica south to Paraguay and Chile (Ratcliffe and Cave 2006), yet GBIF shows records for Panama north to Southern Mexico and even has a record in the U.S. Ratcliffe and Cave said that all specimens labeled C. amazona that they examined from areas north of their distribution turned out to be C. multiplex. All of these GBIF specimens need to be reexamined to determined whether they really are C. Amazona or whether they are the very similar looking C. multiplex.

Therefore:
1) Problem: These data do not conform with the most recent publications regarding species distribution and need to be reexamined.
2) Data available: 817 specimens from the Instituto Nacional de Biodiversidad (Costa Rica), 6 specimens from the University of Kansas Biodiversity Research Center, and 299 specimens from the Texas A&M University Insect Collection.
3) Data limitation: Specimen data from only these three institutions have been submitted to GBIF.
