FIGURE 12. Distribution of 18 Lobocriconema haplotype groups. Major clades A, B and C are enclosed by boxes, members of clade D are encircled. Triangles identify geographic outliers in the dataset. Boxes and circles without color represent putative endemics, recovered only from that specific location. Colors identify shared group membership. Green outline indicates the geographic range of clade A. Red outline indicates clade C minus the Utah outliers, (groups 3 and 16), group 17, and the endemic clade B (group 2). Blue, magenta, and orange outlines indicate distributions within clade D, Gulf Coast and southern Ozark and Appalachian, Gulf Coast, and north–south corridor respectively.

Data from: Negative legacy effects of past forest use on native plant diversity in semi-natural grasslands on ski slopes
<p>We collected this data in Sugadaira and Minenohara Kogen in 2015, and in Kazawa, and Yunomaru in 2016. It was used for our paper titled "Negative legacy effects of past forest use on native plant diversity in semi-natural grasslands on ski slopes".</p>
Threats of land use to the global diversity of vascular plants
<p>Inputs, outputs, and scripts used in the model that supports the findings of the article "Threats of Land Use to the Global Diversity of Vascular Plants". We first calculated the extinction threat at ecoregion level using the countryside species-area model. Next, we allocated the regional extinction threats to land use. Finally, we calculated the global extinction threat per ecoregion and land use.</p> <p>In this repository, you will find the inputs necessary to run the model, the R scripts to run the model, and the outputs of the model.</p>

Diverse root strategies associated with fast to slow resource acquisition vary among plant growth forms
<p>Root acquisition strategies at regional and global scales are largely associated with climate, soil resource availability, and plant phylogeny, yet the drivers at the local scale are not well-quantified. We sampled 115 species across five growth forms (i.e. trees, shrubs, lianas, herbs, and ferns) from a temperate forest and measured seven key functional traits of first-order roots, including root morphology, anatomy, and chemistry. Most trait variations were greater among growth forms than within them. Importantly, species aggregated in root economics space separately by growth forms, illustrating consistent differences in soil resource strategies among growth forms from fast to slow acquisition. Such diverse strategies among plant growth forms may allow species to avoid strong competition and promote species coexistence in a local forest community. These findings improve our understanding of the mechanisms underlying community assembly and stability from a below-ground perspective.</p>
