Figure S3 from Response to resources and parasites depends on health status in extensively grazed sheep

The effect of NDVI (top row) and tick abundance (bottom row) on the number of recordings of sheep with different FAMACHA scores in buffer zones of 100m around the sampling points. FAMACHA scores range from 1-3 with 1 being the healthiest. The lines represent the fitted values calculated from the GLMM coefficients, whilst controlling for all other explanatory variables in the NDVI × FAMACHA (top row) and ticks × FAMACHA (bottom row) models at their mean value in the data set. The points represent the actual number of sheep recordings in tick sampling sites with different transparencies representing the number of sheep recordings (i.e. darker points equal more recordings).
