Join-count statistics of healthy and diseased A. cauliformis in 10×10 m grids at two sites in the Bahamas.

Joins are represented as observed vs. expected (based on a random distribution) number of H:H = healthy:healthy, H:D = healthy:diseased, D:D = diseased:diseased; Total = total joins in a grid. P = the proportion of random diseased:diseased joins that were greater than or equal to the observed number of diseased:diseased joins. T. rate = transmission rate, calculated as observed D:D divided by observed D:D plus H:D. BP = Big Point and RG = Rainbow Gardens. Bold numbers = significant values and Underlined numbers = trends in the results. The dashed line represents the occurrence of Hurricane Irene.
