Changes in the distribution of mechanically dependent plants along a gradient of past hurricane impact.

Batke SP, Kelly DL - AoB Plants (2015)

Bottom Line: The variables that explained much of the community differences of life-forms and families among branches were branch surface area and bryophyte cover.The factors that explained most variation at a plot level were mean vapour pressure deficit and elevation.We believe that more emphasis needs to be placed on the effects that past disturbance events have on mechanically dependent plant communities, particularly in areas that are prone to catastrophic perturbations.

Boxplot and kernel density plot of the Simpson's diversity index in relation to predicted hurricane impact for the EVSS south solution (southerly wind direction = best fit solution). Significant differences (α = 0.05) between impact levels are indicated by letters.

PLV096F3: Boxplot and kernel density plot of the Simpson's diversity index in relation to predicted hurricane impact for the EVSS south solution (southerly wind direction = best fit solution). Significant differences (α = 0.05) between impact levels are indicated by letters.

Mentions: Dependent plant diversity decreased with increasing predicted hurricane damage (Simpson's diversity index, ρ = −0.68, P < 0.01 and species richness, ρ = −0.57, P < 0.01; Fig. 3). Similarly, species richness and diversity were negatively correlated with increased canopy openness (richness: ρ = −0.369, DF = 59, P < 0.01; Simpson's diversity: ρ = −0.531, DF = 59, P < 0.01). Pairwise comparisons revealed that closed canopies were significantly different (both in terms of diversity and species richness) compared with intermediate and open canopies. However, intermediate canopies did not differ significantly from open canopies. Furthermore, dependent plant diversity (but not richness) was correlated with tree type: conifer trees had a significantly lower dependent plant diversity compared with angiosperm trees (Simpson's diversity: conifer D′ = 0.79, ρ = −0.311, DF = 17, R2 = 0.84, P = 0.03, versus angiosperms D′ = 0.84, richness: ρ = −0.221, DF = 41, R2 = 0.01, P > 0.05).Figure 3.
