Figure 2From: Nectar sugars and bird visitation define a floral niche for basidiomycetous yeast on the Canary Islands Point biseral coefficient plot. Point-biserial correlation coefficients of ascomycetous and basidiomycetous yeast species calculated for nectar type (hexose- or sucrose-dominant) of isolation substrate. Significant correlations of distribution and the respective factor level is indicated by * p < 0.05.Back to article page
