SNE01 Species richness, community evenness (Evar) and ANPP effects of nitrogen addition across a gradient of 8 levels in a semi-arid shortgrass steppe and a mesic tallgrass prairie, 2014-2018
This dataset contains the first five years (2014-2018) of the effect of nitrogen addition on species richness, species evenness (Evar) and productivity for a long-term nitrogen addition gradient experiment in two North American grasslands: a semi-arid shortgrass steppe and a mesic tallgrass prairie. Fertilization with time-release urea has been on-going since 2014 in a gradient of eight levels: 0, 2.5, 5, 10, 15, 20, 30 g/m-2. The effect of nitrogen on richness, evenness and Aboveground Net Primary Productivity (ANPP g/m-2 yr) is calculated as the absolute change in value from control plots to treatment plots within each block.

Data from: Diversity among rare and common congeneric plant species from the Garry oak and Okanagan shrub-steppe ecosystems in British Columbia: implications for conservation
<p>Using universal non-coding chloroplast DNA markers (cpDNA), we investigated genetic diversity and genetic structure in four rare and common plant species pairs inhabiting threatened ecosystems (Garry Oak and Okanagan shrub-steppe) in British Columbia. <span>The species found in the Garry oak ecosystem are:</span><span> </span><em>Sanicula bipinnatifida </em><span>(purple sanicle; Apiaceae; rare),</span><span> </span><em>Sanicula crassicaulis </em><span>(Pacific sanicle; Apiaceae; common), and</span><span> </span><em>Balsamorhiza deltoidea </em><span>(deltoid balsamroot; Asteraceae; rare). The species found in the Okanagan shrub-steppe ecosystem are:</span><span> </span><em>Balsamorhiza sagittata </em><span>(arrowleaf balsamroot; Asteraceae; common),</span><span> </span><em>Orthocarpus barbatus </em><span>(Grand Coulee owl-clover; Orobanchaceae; rare),</span><span> </span><em><u>Orthocarpus </u>luteus </em><span>(yellow owl-clover; Orobanchaceae; common),</span><span> </span><em>Phacelia ramosissima </em><span>(branching phacelia; Hydrophyllaceae; rare), and</span><span> </span><em>Phacelia linearis </em><span>(thread-leaved phacelia; Hydrophyllaceae; common). </span>Eight cpDNA regions were sequenced for each study species. Sequences were aligned and concatenated within each species, and single nucleotide polymorphisms (SNPs) were used to analyze patterns of regional genetic diversity and phylogeographic structure within genera and species. Results include: total gene diversity (Ht), nucleotide diversity (π), number of private alleles, haplotype networks, isolation by distance, and analysis of molecular variance. </p> <p> </p>
