Figure 2From: Scale-dependent effects of habitat area on species interaction networks: invasive species alter relationshipsCorrelation coefficients between forest area and numbers of species at each radius (range: 120–2020 m) among the study forests: (a) including exotic species, (b) excluding exotic species and the native species only observed interacting with exotics. Correlation coefficients in the shaded grey areas are statistically significant at p = 0.10 level.Back to article page
