Fig. 2: Floristic similarity trends for each site ordered by elevation.
From: Floristic homogenization of South Pacific islands commenced with human arrival
The direction and steepness of the floristic similarity trends is based on the standardization-1 dataset between sites (n = 14 site comparisons as we exclude comparisons within a given site) based on pairwise Bray–Curtis similarity slope coefficients. Sites are organized by elevation with the lowest (sea level) on the left to the highest on the right (760 m a.s.l.). Data points above the grey horizontal dashed line are differentiating trends and below this line are homogenizing trends. The black horizonal lines indicate the medians of the data for each site, and the blue bars encompass the first and third quantiles of the data. Whiskers extend to the maximum and minimum of the data.
