Relationships between leaf area index (LAI), stand structural and environmental variables in moist forest and miombo woodland of Hanang district in Tanzania.

<p>(A) LAI shows a non-linear relationship with predominant height, (B) linear relationship with tree species richness, (C) soil nitrogen, (D) soil pH under high disturbance levels, (E) stem density and (F) tree species evenness when all other variables are set to their mean values (<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0142784#pone.0142784.s004" target="_blank">S2 Table</a>, combined models). Solid lines plot fitted partial regressions from generalized linear models, with standard errors of the mean in dotted lines.
