Supplement 1. Survivorship, survivor mass, and individual mass of Trichoplusia ni larvae with multiple levels of landscape fragmentation, larval density, and food density.

File List datasetA.txt: Data set of survivorship and survivor mass for all fragments in all treatments. datasetB.txt: Data set of mass of some individual survivors in selected fragments. Description datasetA.txt The file is a tab-delimited ascii file. Survivorship and survivor mass for all fragments in all treatments. Each line is compiled data for one fragment. Column definitions: 1 = EXPERIMENT: Experiment 1 is coded as 1. Experiment 2 is coded as 2. 2 = REP: Experiment 1 was repeated five times, coded 1 through 5; experiment 2 repetitions are coded 6 through 10. 3 = T. NI: BUGHOM indicates that T. ni were distributed homogeneously. BUGHET indicates that T. ni were distributed heterogeneously. 4 = FOOD: HET indicates that food was distributed heterogeneously. HOM indicates homogeneous food distribution. 5 = M/UM: Matched treatments are coded as M, unmatched treatments as UM. 6 = FRAG: Fragmentation levels are HIGH, LOW, or NO (no fragmentation). 7 = FOODAMT: The number of units of food in the fragment. 8 = INTRO TNI: The number of T. ni individuals initially introduced into the fragment. 9 = SURVIVORS: The number of surviving T. ni at harvest. 10 = BIOMASS: Total mass of the survivors in the fragment (mg). Checksum values: Columns 7–10 checksum: Column 7: 5175.5 (13 missing values) Column 8: 23525 (13 missing values) Column 9: 16749 (13 missing values) Column 10: 2365878 (15 missing values) datasetB.txt The file is a tab-delimited ascii file. Mass of some individual survivors* in selected fragments**. *Survivors were chosen to be weighed in order of physical proximity to a corner or to the center of the cell. The same corner (e.g., bottom right) or the center was used throughout a rep; the corner or center for each rep was chosen randomly at the beginning of collection and not repeated until all four corners and the center had been used. **Fragments were selected based on practical feasibility (e.g., how many fragments can be adequately sampled in the laboratory time available) and physical location (e.g., the bottom left cells within each combination of food and larval density). Some cells were sampled as a substitute for adjacent cells as a result of experimenter haste (weighing larvae in a given cell as a group before weighing them individually, thus making them unsuitable for individual weighing). 1 = EXPERIMENT: Experiment 1 is coded as 1. Experiment 2 is coded as 2. 2 = REP: Experiment 1 was repeated five times, coded 1 through 5; experiment 2 repetitions are coded 6 through 10. 3 = T. NI: BUGHOM indicates that T. ni were distributed homogeneously. BUGHET indicates that T. ni were distributed heterogeneously. 4 = FOOD: HET indicates that food was distributed heterogeneously. HOM indicates homogeneous food distribution. 5 = M/UM: Matched treatments are coded as M, unmatched treatments as UM. 6 = FRAG: Fragmentation levels are HIGH, LOW, or NO (no fragmentation). 7 = INDEX: Fragments in each treatment are indexed by physical position. Fragments in high fragmentation treatments are indexed A through P; fragments in low fragmentation treatments are indexed A through D. Fragments are arranged as follows: A C E G B D F H I K M O J L N P High fragmentation treatment A C B D Low fragmentation treatment 8 = FOODAMT: The number of units of food in the fragment. 9 = INTRO TNI: The number of T. ni individuals initially introduced into the fragment. 10 = INDMASS: Mass of surviving individual (mg). Columns 8–10 checksum: Column 8: 34766.5 Column 9: 158200 Column 10: 217607 There are no missing values, but there are 1356 values in each column.
