Data from: Increased soil temperature and decreased precipitation during early plant life stages constrain grass seedling recruitment in cold desert restoration
1. Seed-based restoration is one of the most difficult challenges for dryland restoration. Identifying environmental conditions that drive variation in seed and seedling mortality across similar restoration efforts could increase understanding of when and where restoration outcomes are likely to be favorable and identify new tools and strategies to improve outcomes. 2. We asked how variation in a suite of environmental predictors influenced germination, emergence, seedling establishment, and juvenile survival of four commonly sown perennial grass species across 33 seeding experiments distributed over a ~160,000-km2 area of the Great Basin, a cold desert system in the western United States. 3. Across experiments, we observed wide variation in the rates of four demographic transitions and wide variation in environmental conditions experienced by plants at each stage. For all species, higher precipitation during the first 30 days following seeding was associated with an increase in germination. Conversely, higher soil temperature over this same time period was associated with a significant decrease in germination and emergence and soil temperature was associated with a substantial portion of the variation in germination and emergence probabilities observed across our seeding experiments. 4. Within the range of precipitation variation observed, we were unable to detect a significant relationship between seedling establishment the first growing season and cumulative precipitation the first year, precipitation during the first spring growing season, or annual climatic water deficit (CWD) the first year. Higher CWD the second growing season reduced seedling survival over that time period. 5. Synthesis and application. Our results show higher soil temperature negatively impacts grass seedling recruitment. Our results can be combined with seasonal and subseasonal temperature forecasts to improve restoration decision-making. These results also suggest climate warming will make restoration even more difficult, with our model estimates suggesting the 2°C increase in temperature expected in the Great Basin over the coming decades will decease germination and emergence by about 30%. Lastly, while our field-based approach provided insight into short-term drivers of mortality, it did not provide insight into drivers of longer-term survival, suggesting a need to develop process-based approaches for predicting long-term restoration outcomes.29-Aug-2019
Data from: Seed supply, recruitment, and assembly: quantifying relative seed and establishment limitation in a plant community context
There is growing consensus that the relative constraints of seed limitation and establishment limitation in recruitment strongly influence abundance patterns in plant communities. Although these constraints have direct relevance to coexistence, most investigations utilize a seed addition approach that offers limited insight into these dynamics. Here we report results of an assembly experiment with annual plant species of California grasslands to examine how propagule pool characteristics (dominant species abundance, functional diversity) influence establishment and seed limitation (density independence and density dependence across a gradient of seed supply) for each species, and how these constraints affect community diversity. Species were predominantly co-limited by seed and establishment constraints, exhibiting saturating recruitment functions with increased seed supply. Consistent with competition-colonization trade-off predictions, recruitment constraints often depended on the degree of seed limitation of the competitive dominant, Brassica nigra; diversity was greatest in communities where Brassica was seed limited. Functional similarity within the propagule pool did not affect recruitment across a range of seed supply; likewise, functional diversity of the propagule pool was not related to community diversity. We conclude that seed limitation of the dominant species rather than niche similarity influences interspecific competition for safe sites and scales up to affect community-level diversity.
Effects of biochar soil amendments on soil properties and plant recruitment in coastal climate change adaptation projects
<p>Biochar is a carbon-rich material produced through the pyrolysis of organic waste from the agricultural and forestry industries. Because black carbon is chemically stable, its application to agricultural fields is being touted as a method to mitigate greenhouse gas emissions as it has been shown to improve the fertility of the soil and crop yields as well as increase carbon sequestration. This data publication archives data from a set of paired restoration projects that incorporated biochar soil amendments to test the ability of biochar to provide positive ecosystem or carbon sequestration benefits.</p>
