Fig. 4: Non-metric multidimensional scaling (NMDS) ordinations of fish, amphibian, and crayfish species assemblages.
From: Following megafires fishes thrive and amphibians persist even in severely burned watersheds
NMDS ordinations indicating the structure of stream assemblages of fish, amphibians, and crayfish species across all study sites over three years in western Oregon, USA (n = 79). a Significantly correlated environmental variables (p < 0.005) are indicated by vectors where the vector length represents the Pearson’s correlation (r) between quantitative variables along ordination axes. b Significantly correlated species (p < 0.005) are indicated by vectors where the vector length represents the Pearson’s correlation (r) between species abundances along ordination axes. c Vectors indicating assemblage shifts over time within sites.
