On 02/04/16 Thursday afternoon, Andrew, Logan, Boha and I (Saisi) got together in the conference room and talked our firefly dataset (https://figshare.com/articles/LTER_Lampyrid_data/2068098) for the first time. The discussion was productive, and we obtained: 1. the metadata and DRP (Data Reuse Plan) information of the dataset. 2.Hypothesis on data analysis and paper drafting, and questions for Christie on how we can dig into the data deeper.

2. Hypothesis and questions:
Preliminary test: By sorting the data and plotting firefly population with different variables (Logan is a quick plotter!), we find correlation between population with year, tilling and landscape.
Therefore, we had the hypothesis that population of fireflies is dependent on hab type + year + organic/not + (weather + temperature). And to decouple the effects of diffrent factors, we may take snapshot of each year to study habitat type and treatment (organic, tilling, etc.,).
Questions remain: Do we need a model of population (dependent variable) depends on year and habitat types (two most significant independent variable)? If yes, is there an empirical model we can get from previous papers? What parameters should we estimate? How many variables should we consider? If we are not going to develop a mathematic model, what statistical analysis should we run?
