Best selected tree from a maximum likelihood reconstruction for the cytochrome c oxidase subunit I data set under the general time reversible model with gamma distribution, displaying all compatible groupings and with average branch lengths proportional to numbers of substitutions per site, indicated by the scale bar. Bootstrap support values above 80% are shown below each branch; posterior probabilities above 0.8 from 36 000 sampled trees from the Bayesian analysis are shown above each branch. Support values for within-species relationships are not shown. Filled circles indicate clades (and singlets) identified by the 4¥ rule; open diamonds indicate clades (and singlets) identified by the generalized mixed yule coalescent model. Names refer to the species and the clonal populations.

Data from: Changes in beta diversity and species functional traits differ between saplings and mature trees in an old growth forest
<p class="MsoCommentText">1. Invasion by generalist tree species can cause biotic homogenization and such community impoverishment is likely more important in rare forest types. We quantified changes in tree diversity within Carolinian (range in Central Hardwoods), northern (range reached Northern hardwood-conifer/Boreal-spruce-fir) and central species (range in Central Hardwood region and Northern hardwood-conifer) in an old forest in southern Canada at points surveyed 24 years apart.</p> <p class="MsoCommentText">2. We asked: How did mature tree and sapling composition and abundance change for the 3 species' groups? Did those changes lead to biotic homogenization? Can species' changes be explained by community traits? We tested for differences in temporal and spatial tree <span>β</span>-diversity, as well as forest composition and structure, using univariate/multivariate analyses and a community trait-based approach to identify drivers-of-change.</p> <p class="MsoCommentText">3. Major increases occurred in abundance for mature <i>Acer rubrum</i> (northern), while others decreased (<i>Fraxinus americana</i>, <i>Populus grandidentata</i>); declines were found in <i>A. saccharinum </i>(central) and <i>Cornus florida</i> (Carolinian). Species composition of saplings, but not mature trees, changed due to replacement; no evidence for biotic homogenization existed in either cohort. As a group, northern mature tree species increased significantly, while central species declined; saplings of Carolinian species declined. </p> <p class="MsoCommentText">4. Shade-tolerance in mature trees increased, reflecting successional changes, while drought-tolerance decreased perhaps due to changing temperatures, altered precipitation or ground water levels. Saplings showed declines in all traits, probably because of compositional change. </p> <p class="MsoCommentText">5. Our results demonstrated that saplings can more closely reflect change in forest dynamics than mature trees, especially over short time periods. Based on sapling trends, this remnant could ultimately transition to a mesophytic hardwood stand dominated by <i>A. rubrum</i> and other shade-tolerant species, creating a more homogeneous forest. </p> <p class="MsoCommentText">6. While encouraging regeneration for Carolinian and central tree species could ensure high levels of diversity are conserved in the future, it is important that this is balanced with the primary management goal of maintaining the older-growth characteristics of the forest.</p>
