Data for: Sun, Ogushi, Tseng -Lepidoptera species richness and community composition in urban street trees
<p>The triple threats of climate change, habitat loss, and environmental pollution have stimulated discussion on how urban areas can be modified to both mitigate heat increases and provide habitat for wildlife such as insects. The strategy of using trees to reduce temperatures has been adopted by numerous cities. However, the majority of street trees planted around the world are non-native. Studies conducted in non-urban areas have demonstrated in comparison to native plants, non-native plants are less likely to support native insect diversity. Here we use a database approach to quantify the number of native Lepidoptera species associated with 76 of the most common street tree species planted in Vancouver, Canada. We tested the prediction that compared to non-native trees, native street trees will support a higher diversity and unique community of native Lepidoptera. As predicted, native street trees were associated with five times as many native Lepidoptera species, and the Lepidoptera communities supported by native vs. non-native street trees were distinct. There was no difference in native Lepidoptera associations between broadleaf vs. coniferous street trees. These results are consistent with studies that have used active sampling techniques to investigate insect richness on a smaller subset of native and non-native tree species. Collectively, these data provide good evidence that the planting native instead of non-native trees will help stem the loss of insect diversity in urban areas.</p>
Increases in Species Richness Lead to Decreases in Phylogenetic Diversity in Mediterranean Species Assemblages
<p><span>The relationship between taxonomic and phylogenetic diversity remains underexplored. Our goal was to determine whether a causal link exists between species richness and phylogenetic diversity. We wanted to evaluate whether species richness determines the phylogenetic diversity in realized assemblages (<em>taxonomic determinant hypothesis</em>) or phylogenetic diversity determines the species richness (<em>phylogenetic determinant hypothesis</em>). We also hypothesize that this causal framework could shift in different bioclimatic regions. We sampled over 1700 plant assemblages in grasslands and shrublands across three bioclimatic regions in Navarra, Spain. Using non-recursive structural equation modelling, we found that species richness influences phylogenetic diversity, and </span><span>that this causal relationship remains consistently negative and is unaffected by climate differences among regions</span><span>. Specifically, greater plant richness leads to increased phylogenetic convergence, resulting in reduced phylogenetic diversity. This means that the incorporation of new species into assemblages involves adding closely related species in phylogenetic terms, regardless of the bioclimatic region.</span></p>
