Tree DBH.csv: This data was compiled to compare the diameters of each of the trees used in the subsequent experiments to determine if they were similar in size 2. Phloem Thickness: This data was compiled to determine whether thickness of the phloem in each log was similar or different. This is important since the thickness of the phloem may determine other behaviors. 3. Bark Acceptance: This data is the result of experiments conducted to determine the proportion of female mountain pine beetles that enter a log per day. Beetles were caged on respective logs and number entering at each 24 hours period was recorded. 4. Phloem Acceptance: This data is binomial data showing the female beetles that rejected (1) or accepted (0) the phloem of a cut log in 12 hours time. 5. Continued Acceptance: This data is binomial data showing the female beetles that had fertile (1) or infertile/rejected (0) egg galleries after winter had commenced. 5. Attraction: This data shows the number of beetles caught in funnel traps associated with infested cut logs of eastern and western pine species across two years. In the first year each row is the total collected for that trap for a week. For the second year each row is all beetles caught for 2 days. 6. Chemical Comp: The concentration of specific chemicals present in samples of phloem from various pine species used in this study. Concentrations were measured using a GC/MS. Relative concentrations (those columns with a % symbol) are the relative amounts of each of the first 7 monoterpenes. The relative concentration of 4-allylanisole is the relative amount compared to the total concentration. --------------------------- Additional Data Description --------------------------- 1. The period in the csv files is a placeholder for the statistical analysis. This is recognized in R. 2. Year: A = 2013, B = 2014. 3. Species: Scots = Pinus sylvestrus, Red = Pinus resinosa. 4. Region: Historical or Novel. Historical = Pine trees with a historical relationship with mountain pine beetle. Novel = Pine trees with no known historical relationship with mountain pine beetle. 5. DBH(cm): Diameter at breast height in centimeter. 6. site name: Abbreviation of the site names where the experiments were conducted. They are random locations in the Black Hills from which outbreaks have now moved on. The coordinates are filed away in field notebooks somewhere, but due to the nature of the experiments, these exact locations don't really matter beyond the general location of the experiments in the Central Black Hills. 7.Beetle = Dendroctonus ponderosae Hopkins
