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.

Ecosystem stability is determined by plant defense functional traits and population stability under mowing in a semi-arid temperate steppe
<ol> <li><span>As a common grassland management practice in many high-latitude regions worldwide, mowing has great impacts on grassland functioning and stability. Species richness, species asynchrony and species stability have been suggested as central in responses to environmental change. Mowing can evoke plant defense systems due to physical damages to plants. However, no studies have comprehensively evaluated the role of plant defense functional traits, species richness, species asynchrony and stability in ecosystem functioning under mowing regimes across time-scales. </span></li> <li> <span>In the present study, we set up short-term (4-years) and long-term (16-years) mowing experiments with three stubble heights (control, 10 cm, 2 cm) in a temperate steppe of Inner Mongolia. We investigated the effects of mowing-induced changes in distribution metrics associated with plant defense traits, i.e. mean, variance, skewness and kurtosis of trait distribution, on ecosystem stability of grassland communities using structural equation modeling.</span> </li> <li><span>We found that grassland ecosystem stability was enhanced by increasing mowing duration and decreasing stubble height. Mowing-induced increases in abundance and diversity of plant defense traits contributed to greater ecosystem stability by enhancing species asynchrony and population stability. Moreover, we found that mowing enhanced the abundance and diversity of plant defense traits of dominant species and contributed to population stability and species asynchrony, thus enhancing temporal stability of grassland ecosystems. </span></li> <li><span>These results demonstrate the important roles of plant defense traits in maintaining stability of grasslands under mowing, and highlight that, in addition to species richness, asynchrony and population stability, plant functional defense trait act in stabilizing ecosystem functions under human-induced environmental changes.</span></li> </ol>
