Title Israeli_butterfly_move_data
Downloaded 8 times
Description Primary data for estimating movement rates. UniqueID combines the site name, track number and flight step number. Species are identified in Supplemental Information, Table S3. Field types are Wheat and Olives. Locations are Wheat, Olive, Nature and (Field) Margin. See Figure 1 for visual of field types vs locations. Projected coordinate system is GRS_1980_Transverse_Mercator with False Easting = 219529.584 and False Northing = 626907.390. Each move consisted of a move length, measured as the distance between turning or stopping points i and i+1, and a turning angle θi , measured as the angle between move i-1 and i. The file contains Time (seconds), Length (m) and Turn (Cosine of turning angle). Note that steps starting in edge regions, defined as 10m outside the Margin towards Nature or Fields, were omitted from the analysis (see text for details). However, if a move step starts in one of the included Locations and ends in edge region, the step and associated angle and time was included in the analysis.

Title Israeli_butterfly_diffusion rates_and _densities
Downloaded 5 times
Description Parameters calculated via bootstrapping of movement data and densities (number/ha) from surveys across the sites (see text for details). Parameters include diffusion (m2/sec), Turn (cos of turning angle), Length (move step, m). Time (sec) and Er2 (expected net squared displacement, m2). File includes median and 95% confidence intervals for each parameter. Locations are Wheat, Olive, Nature and (Field) Margin. Wingspan is in cm.
