Organic Farming: Biodiversity Impacts Can Depend on Dispersal Characteristics and Landscape Context
Fig 1
Effects of farming system and landscape (% arable) on activity density of hunting spiders where system effect is significant.
Organic: solid lines, filled points; conventional: dotted line, open points. Plots in left hand panel: lines in plots are linear regressions plotted on log scale by system, points are farms. Plots in right hand panel: lines in plots are linear regression (solid line) and reference line (dotted at system difference = zero), points are farm pairs. Right hand panel extracts system effect from left hand panel, O-C difference on arithmetic scale.
