Title Data from Drosera rotundifolia leaves
Downloaded 20 times
Description These data relate to measurements of the leaves of Drosera rotundifolia plants growing at Thorne Moor, Lincolnshire, UK. Prey were measured directly after removal from the leaf. Leaf colour data were collected electronically by analysis of digital photos. ‘Time’: date of measurement - 1=08/09/2012 2=15/09/2012 3=22/09/2012. ‘Plant’: plant i.d. ‘LeafArea’: Leaf area (mm^2) based on measurement of the longest axis and the axis perpendicular to that. Area calculated assuming leaf is an ellipsoid. ‘PreyCt’: number of captured arthropod prey removed from the leaf. ‘PreyLth’: Length of captured arthropod prey. ‘PreyArea’: Number of arthropod prey per unit leaf area (prey mm^2). ‘TrapL*’: Trap/leaf L*. ‘Trapa*’: Trap/leaf a*. ‘Trapb*’: Trap/leaf b*. ‘BGL*’: Background L*. ‘BGa*’: Background a*. ‘BGb*’: Background b*

Title Data from artificial traps placed on natural backgrounds
Downloaded 11 times
Description These data relate to measurements of captured arthropod ‘prey’ removed from different coloured artificial traps placed on the bog surface at Thorne Moor, Lincolnshire, UK. Each record relates to a single prey item. Prey were measured directly. Colour data are from electronic image analysis of digital photos. ‘Time’: date of removal of trap from bog (traps were in place for 7 days) - 1=08/09/2012 2=15/09/2012 3=22/09/2012. ‘Trap’: Trap i.d. TrpClr: Trap colour (Red, Green or transparent/clear). Length: length of prey item (mm). Width: width of prey item (mm). Order: Taxonomic order to which prey item belongs.

Title colour data for artificial traps placed on natural backgrounds
Downloaded 7 times
Description These data relate to measurement of the colour of the artificial traps used in the ‘artificial traps on natural background’ part of the study. Each record related to measurement of the colour of a single trap and its background. Data were measured electronically using image analysis of digital photographs. ‘Trap’: trap i.d. (these relate directly to ‘trap’ in ‘Artificial_On_Natural’. Colour: Trap colour (red, green or clear). ‘TrapL*’: Trap L*. ‘Trapa*’: Trap a*. ‘Trapb*’: Trap b*. ‘BGL*’: background L*. 'BGa*’: Background a*. ‘BGb*’: Background b*. 'DeltaE76’: Delta E76 for difference between trap and background.
