Part of being open in science is making your data available for collaborators and interested parties. Although this is not always possible, especially if your data sources wish to remain private, data that I collect will be cleaned up and shared here.
During my doctoral dissertation, I collected quite a large amount of data on Pieris virginiensis and its host plants. For example, we colleced an unidentified caterpillar that may have been P. virginiensis on garlic mustard. This was while we were looking for P. virginiensis in Morrow Co., OH, and you can view the rest of that site specific data as well. I have also tabulated all of the egg occurrences in our various field sites for easy viewing, and examined the behavior of both P. virginiensis and the European congener P. rapae. I also tried to feed P. virginiensis some A. petiolata and tracked their survival. We also performed some damage analysis with P. rapae and A. petiolata in the field. Finally, I grew A. petiolata with the two native mustards that P. virginiensis uses to examine competition, and with an undergrad, took a look at the type and quantity of cyanide that A. petiolata produces.
Much of the data I work with now is publicly available from the US Forest Service's Forest Inventory and Analysis program. I'm working on developing three packages in R to deal with forest data. More information about these three R packages can be found on the GitHub landing pages for MakeMyForests, disperseR, and SortieIO.
