Supplementary Materials from Increases in local richness (α-diversity) following invasion are offset by biotic homogenization in a biodiversity hotspot Alessandra R. Kortz Anne E.

Cerrado biodiversity hotspot distribution in Brazil (thicker line), the second largest vegetation formation in South America, and the study area location: Itirapina Ecological Station. Map elaborated using DIVA-GIS version 7.5 [1]; Biomes of Brazil shapefile obtained from [2]; Table S1. The relationship between total number of species per plot and number of invasive species per plot using a linear model. In total, 300 5x5m plots were sampled,114 in campo sujo and 186 in campo úmido. In both cases there is a significant relationship (Pr(>|t|) in bold).; Table S2. Partitioning of total Jaccard dissimilarity (βjac) into turnover (βjtu) and nestedness (βjne) (in relation to the percentage of total Jaccard) calculated with the beta.multi function in the betapart package from R [4,5]. Turnover dominates biodiversity change in all cases in both campo sujo and campo úmido habitats.; Table S3. Kruskal-Wallis results of the multiple comparisons of total Jaccard dissimilarity (βjac) between plots with native species only, and plots with 1, 2 or 3 to 4 invasive species in both campo sujo and campo úmido habitats. Bonferroni correction for multiple comparisons was applied.; Figure S2. Percentage of occurrence of invasive species (open triangles) and native species (filled circles) in all sampled plots. Each plot that contained one isolated pine (Pinus elliottii) individual (a and c) was paired with one plot with no pines (b and d) in both campo sujo and campo úmido habitats. The three other invasive species present (all grass species) were: Melinis repens, Melinis minutiflora and Urochloa decumbens. Invasive grass species are widespread amongst all conditions. 2019-04-27 12:35:10 biodiversity change invasion impact β-diversity Cerrado species richness
