Ecological resilience of physical plant–soil feedback to chronic deer herbivory: slow, partial but functional recovery
<p>Ecological resilience to ungulate overbrowsing is an important issue in forest ecosystem. After chronic herbivory, the recovery rate of understory vegetation and its related functions can be slow even with decreasing grazing intensity; thus, detecting elasticity during alternative successional trajectories is fundamental to understanding state perturbations. In this context, we focused on physical plant–soil feedback (functional interactions between plant growths and soil physical conditions), and evaluated elasticity and recovery processes according to deer density. The effects of 40-year chronic herbivory by sika deer (average density 14.7 individuals km<sup>-2</sup>) on the recovery of understory plant communities and associated improvements in soil physical properties in headwater catchments were assessed. Using 8 years of catchment-wide exclusion (fenced) and reduction (only culled; average 4.3 individuals km<sup>-2</sup>) treatments, plot sampling was conducted in 2010 (before treatment) and 2018 (after treatment). The recovery of vegetation and soil physical properties were evaluated, and functional plant–soil relationships and spatial variability were assessed to detect recovery processes during alternative successional trajectory. Woody species increased only under the exclusion treatment and the average soil bulk density was lower than that under reduction treatments. Soil bulk density was negatively correlated with root biomass in the fenced catchment, and root biomass was positively associated with woody species richness. Reduced soil bulk density (~0.5 g cm<sup>-3</sup>) was observed with greater root biomass and woody species richness on upper hillslopes in the deer-excluded catchment where plant coverage was minimal. Successional failure under the reduction treatment suggested slow recovery with a depressed threshold according to deer density, indicating a clockwise hysteretic response to deer density. Unlike plant coverage during the earlier period of overbrowsing, woody species root development led the recovery of functional physical plant–soil feedback; however, this was probably limited by the higher soil erosion rate in riparian areas and an underdeveloped herb layer. Our results highlight an alternative recovery trajectory of physical plant–soil feedback driven by an alternative plant element (woody roots) to degradation trajectory with decreasing plant cover. However, riparian erosion and herb layer would still suppress recovery. Therefore, recovery might be slower at landscape scale.</p>

Computational Artifacts for Performance Feedback Autoscaling Experiments with Workloads of Workflows in Apache Airflow
<p>These computational artifacts are related to the software artifacts DOI:10.5281/zenodo.2635571</p> <p><strong>The content of the computational artifacts:</strong></p> <ul> <li><strong>experiments.pdf</strong> contains the list of all the conducted experiments with the Airflow system. Experiment IDs are not sequential since some experiments required rerunning, etc., we report only successful results. The file lists different experiment configurations, e.g., the number of processed workflows, the name of the used workload, the user budgets, and PFA settings.</li> <li><strong>db.tar.gz</strong> contains directories with Airflow database snapshots and autoscaler logs. The names of the directories correspond to those listed in `experiments.pdf`. Each experiment directory contains an autoscaler log and a full copy of a PostgreSQL database directory just after each experiment finished. The database name is `airflow`, the user name is `ailyushk`. Within each database, most of the paper-related data are stored in the `stat_log` table. The scripts for extracting data from these databases are available as software artifacts in `tools/analysis`.</li> <li><strong>gurobi.tar.gz</strong> contains the results obtained from the Gurobi solver when solving the MIP model.</li> <li><strong>pdf.tar.gz</strong> contains all the figures in pdf format, also those that were not included neither in the paper nor in the technical report. The scripts for creating this plots are delivered as software artifacts.</li> <li><strong>csv.tar.gz</strong> contains the analysis results extracted from Airflow database snapshots. These files are used to create the plots in the `pdf` directory. The scripts for doing this are delivered as software artifacts.</li> <li><strong>wl1.tar.gz</strong> is the first synthetic realistic workload (WL I) with three subsets of 200 workflows each (`1_0`, `1_1`, `1_2`). Each directory contains the file with interarrivals `interarrivals.txt`, and the file with workflow IDs `workload.txt` in the subset. The `dags` directory contains Python-based Airflow descriptors and CSV files that summarise the same descriptors in CSV format for simpler analysis. The scripts for extracting workload statistics from these CSV files are available in the software artifacts in `tools/analysis`. The `inputs` directory contains initial input files for each worfklow. The `dax` contains original DAX files obtained from the generator: <a href="https://github.com/pegasus-isi/WorkflowGenerator/tree/master/bharathi/src/simulation/generator">https://github.com/pegasus-isi/WorkflowGenerator/tree/master/bharathi/src/simulation/generator</a></li> <li><strong>wl2.tar.gz</strong> is the second synthetic realistic workload (WL II) with three subsets of 200 workflows each (`4_0`, `4_1`, `4_2`). Has similar structure as `wl1.tar.gz`, except that `dax` directory is omitted, as WL II uses the same DAX structures as WL I.</li> <li><strong>wl3.tar.gz</strong> is the small synthetic workload based on WL I for the experiment with the MIP solver, contains three subsets with 5 workflows in each, all in the `3_0` directory (thus, the structure differs from the WL I and WL II). The input data files are empty. The identifiers of workflows forming each subset are stored in the `workload_1.txt`, `workload_2.txt`, and `workload_3.txt` files.</li> </ul>

Data from: Positive feedback between ecological and reproductive character displacement in a young avian hybrid zone
Character displacement can reduce costly interspecific interactions between young species. We investigated the mechanisms behind divergence in three key traits - breeding habitat choice, timing of breeding and plumage coloration - in Ficedula flycatchers. We found that male pied flycatchers became expelled from the preferred deciduous habitat into mixed forest as the superior competitor, collared flycatchers, increased in numbers. The peak in food abundance differs between habitats, and the spatial segregation was paralleled by an increased divergence in timing of breeding between the two species. Male pied flycatchers vary from brown to black with brown coloration being more frequent in sympatry with collared flycatchers, a pattern often proposed to result from selection against hybridization, i.e. reinforcement. In contrast to this view, we show that brown male pied flycatchers more often hybridize than black males. Male pied flycatcher plumage coloration influenced the territory obtained in areas of co-occurrence with collared flycatchers, and brown male pied flycatchers experienced higher relative fitness than black males when faced with heterospecific competition. We suggest that allopatric divergence in resource defense ability causes a feedback loop at secondary contact where male pied flycatchers with the most divergent strategy compared to collared flycatchers are favored by selection.
