Abstract:
Shea et al (1993) studied the small-scale spatial patterning of water tupelo, a gynodioecious tree. Locations of all trees in 50m x 50m quadrats were mapped using compass and tape. By inspection of flowers in spring, each tupelo was classified as male, female, or juvenile (not flowering). The biological questions concern spatial segregation. Do males tend to occur in the vicinity of other males. Do females tend to occur in the vicinity of other females? The data are records of all water tupelo trees in 3 approx. 50 m x 50m plots in bottomland hardwood forests. They are formatted as plot, sex (F = 1, M = 2, or juvenile = 3), index number of nearest neighbor (If a tree 1 in a plot has a value of 185 for nearest neighbor, tree 185 is its nearest neighbor), x and y (the spatial location in meters).
