Dendrogram based on cluster analysis of morphometric measurements of the top 5 Kruskal Wallis characters with a value greater than 18. Distance matrices were calculated using the Gower metric (GM) and cluster analysis was performed using unweighted pair-group method using arithmetic averages (UPGMA) to produce dendrograms.

Butterfly nectar foraging and flowering plant community data from field surveys in Victoria, British Columbia, Canada

The negative impacts of non-native species have been well documented, but some non-natives can play a positive role in native ecosystems. One way that non-native plants can positively interact with native butterflies is by provisioning nectar. Relatively little is known about the role of phenology in determining native butterfly visitation to non-native plants for nectar, yet flowering time directly controls nectar availability. Here, we investigate the phenological patterns of flowering by native and non-native plants and nectar foraging by native butterflies in an oak savanna on Vancouver Island, British Columbia, Canada. We also test whether native butterflies select nectar sources in proportion to their availability. We found that non-native plants were well integrated into butterfly nectar diets (83% of foraging observations) and that visitation to non-natives increased later in the season when native plants were no longer flowering. We also found that butterflies selected non-native flowers more often than expected based on their availability, suggesting that these plants represent a potentially valuable resource. Our study shows that non-native species have the potential to drive key species interactions in seasonal ecosystems. Management regimes focused on eradicating non-native species may need to re-consider their aims and evaluate resources that non-natives provide.

Fig. 6 in Biosynthesis and emission of methyl hexanoate, the major constituent of floral scent of a night-blooming water lily Victoria cruziana

Fig. 6. Gene expression pattern of VcSABATH1 (A) and VcSABATH3 (B) in four different parts of V. cruziana flowers. Gene transcript levels were measured using RT-qPCR with VcGADPH (glyceraldehyde-3-phosphate dehydrogenase) gene as the internal control. The reactions were performed with three biological repeats, and the data was calculated by 2 ΔΔCT method. The highest levels of expression for each gene were arbitrarily set as 1.0. Different letters denote statistically significant differences among the means according to ANOVA analysis (P <0.05).

Fig. 7. The phylogenetic analysis of VcSABATHs with the SABATH genes identified from N. corolata, non-seed and model species. 39 full-length proteins starting with "Os" are from rice, 24 proteins starting with "At" are from Arabidopsis, seven full-length proteins starting with "NC" are from Nymphaea colorata, five proteins starting with "Pa" are from Picea abies, three proteins starting with "Pt" are from poplar and three proteins starting with "Vc" are from V. cruziana. IAMT: indole-3-acetic acid MT; SAMT: salicylic acid MT; JAMT: jasmonic acid MT; GAMT: gibberellic acid MT; BSMT: benzoic acid/salicylic acid MT; FAMT: farnesoic acid MT. PpSABATH1 from the moss Physcomitrella patterns (Zhao et al., 2012) was used as an outgroup. Bootstrap values of 50 % or higher are indicated. The water lily-specific cluster was shaded.

Fig. 5. GC chromatogram of product of methyltransferase enzyme assays for VcSABATH1-3. The assay conducted with proteins expressed in E. coli with pET32a without any gene insert (empty vector) was used as a negative control. Also shown was the GC chromatogram of the authentic standard methyl hexanoate. Hexanoic acid was used as substrate. While no product was detected from the VcSABATH2 assay, both VcSABATH1 and VcSABATH3 catalyzed the formation of methyl hexanoate (peak 1).

B, chromatogram of three authentic compounds. Peak a1: methyl hexanoate; peak a2: benzyl alcohol (peak 2); peak a3: benzyl tiglate. C. mass spectrum of three compounds from flowers (peaks 1, 2 and 4) and their corresponding authentic standard (peaks a1, a2 and a3).
