BirdNET App data: 2020 case studies
<p>Datasets for four case studies used to test whether BirdNET App data could be used to replicate known patterns in avian ecology and thus serve as a reliable research resource. The case studies were selected based on the availability of results we could attempt to reproduce (e.g., song dialect mapping has been somewhat limited at broad scales because of data limitations) and to encompass a range of phenomena (e.g., simple vs complex songs and the migration of small vs large populations). Researchers interested in collaborations using app data are also encouraged to email <<a href="mailto:ccb-birdnet@cornell.edu">ccb-birdnet@cornell.edu</a>>.</p> <p>Please note that BirdNET confidence scores are <em><strong>not </strong></em>equivalent to probabilities and are unique to each species. That is, a confidence score of 0.85 may have a very different probability of being correct for species A and species B.</p>

Physiological responses of narwhals to anthropogenic noise: a case study with seismic airguns and vessel traffic in the Arctic
<p>Limited polar geographical range, narrowly defined migratory routes, and deep-diving behaviors make narwhals exceptionally vulnerable to anthropogenic disturbances including oceanic noise. Although behavioral studies indicate marked responses of cetaceans to disturbance, the link between fear reactions and possible injury from noise exposure is limited for most species.</p> <p>To address this, we deployed custom-made heart rate-accelerometer-depth recorders on 13 adult narwhals in Scoresby Sound, East Greenland across a five-year period (2014-2018). Physiological responses of the cetaceans were monitored in the absence (n = 13 animals) or presence (n = 2 animals across 3 acoustic events) of experimentally directed, seismic airgun pulses and associated vessels (full volume source level = 241 dB re 1 μPa-m).</p> <p>We found that anthropogenic noise resulted in marked cardiovascular, respiratory and locomotor reactions by two narwhals exposed to seismic pulses across three acoustic events. The general behavioral response to seismic and vessel noise included an 80% reduction in the duration of gliding during dive descents by seismic-exposed narwhals compared to controls, and the prolongation of high-intensity activity (ODBA > 0.20 g) with elevated stroke frequencies exceeding 40 strokes per minute. Noise exposure also resulted intense (< 10 bpm) bradycardia that was decoupled from stroking frequency. This decoupling instigated increased variability in heart rate, with the heart switching rapidly between bradycardia and exercise tachycardia during noise exposure. Maximum respiratory frequency following seismic exposure, 12 breaths.min<sup>-1</sup>, was 1.5 times control levels.</p> <p>Overall, the effect of seismic/ship noise exposure on wild narwhals was a 2.0 – 2.2-fold increase in the energetic cost of diving, which paradoxically occurred during suppression of the cardiac exercise response. This unusual relationship between diving heart rate and exercise intensity represents a new metric for characterizing the level of fear reactions of wild marine mammals exposed to different environmental stressors. Together, the multi-level reactions to anthropogenic noise by this deep-diving cetacean demonstrated how a cascade of effects along the entire oxygen pathway could challenge physiological homeostasis especially if disturbance is prolonged.</p>
Data from: Automated integration of trees and traits: a case study using paired fin loss across teleost fishes
Data synthesis required for large-scale macroevolutionary studies is challenging with the current tools available for integration. Using a classic question regarding the frequency of paired fin loss in teleost fishes as a case study, we sought to create automated methods to facilitate the integration of broad-scale trait data with a sizable species-level phylogeny. Similar to the evolutionary pattern previously described for limbs, pelvic and pectoral fin reduction and loss are thought to have occurred independently multiple times in the evolution of fishes. We developed a bioinformatics pipeline to identify the presence and absence of pectoral and pelvic fins of 12,582 species. To do this, we integrated a synthetic morphological supermatrix of phenotypic data for the pectoral and pelvic fins for teleost fishes from the Phenoscape Knowledgebase (two presence/absence characters for 3,047 taxa) with a species-level tree for teleost fishes from the Open Tree of Life project (38,419 species). The integration method detailed herein harnessed a new combined approach by utilizing data based on ontological inference, as well as phylogenetic propagation, to reduce overall data loss. Using inference enabled by ontology-based annotations, missing data were reduced from 98.0% to 85.9%, and further reduced to 34.8% by phylogenetic data propagation. These methods allowed us to extend the data to an additional 11,293 species for a total of 12,582 species with trait data. The pectoral fin appears to have been independently lost in a minimum of 19 lineages and the pelvic fin in 48. Though interpretation is limited by lack of phylogenetic resolution at the species level, it appears that following loss, both pectoral and pelvic fins were regained several (3) to many (14) times respectively. Focused investigation into putative regains of the pectoral fin, all within one clade (Anguilliformes), showed that the pectoral fin was regained at least twice following loss. Overall, this study points to specific teleost clades where strategic phylogenetic resolution and genetic investigation will be necessary to understand the pattern and frequency of pectoral fin reversals.

Online Appendix of "Crowd-based Requirements Elicitation via Pull Feedback: Method and Case Studies"
<p>The online appendix contains the data sets used in the paper Crowd-based Requirements Elicitation via Pull Feedback: Method and Case Studies, by Jelle Wouters, Abel Menkveld, Sjaak Brinkkemper and Fabiano Dalpiaz. It consists of three data sets, a process-deliverable diagram, a file that contains charts, and two Jupyter (Python) notebook scripts. In this readme, we briefly explain how files should be read and interpreted.</p> <p><strong>Dataset-Tournify.xlsx</strong></p> <p>This file contains all data of the Tournify case. The following tabs are present:</p> <ul> <li> <p>Raw data: contains the raw data collected from the Tournify CrowdRE platform.</p> </li> <li> <p>Automatically translated data: The readability and vagueness measures were calculated using English text. Most of the ideas collected were in Dutch, so the raw data was translated into English using a Google Translator API.</p> </li> <li> <p>Readability scores: Consists of the Flesch and ARI readability scores, calculated using the Python scripts (see below). </p> </li> <li> <p>Vague hits: Consists of all the vague words found in the Tournify ideas. We identified those using a Python script. Using numbers we identified whether the hit was a True Positive (TP) or was a false positive, and in which category the false positive lied. </p> </li> <li> <p>Tagging-50-FD & Tagging-50-JW: These tabs contain the tagging of the ideas on qualities of the QUS-framework and the ISO/IEC 25010. Two researchers did this independently from another.</p> </li> <li> <p>Compare-50: This sheet consists of all ideas for which a disparity exists between the two fields. When a disagreement exists, the field is colored green. By text in the field, we indicated what the final decision was. </p> </li> <li> <p>Result-50: This tab combines the results and shows the final decision after deliberation between the two authors.</p> </li> <li> <p>Tagging-195-FB, Tagging-195-JW, Compare-195, Result-195: Same as above, but for the other 195 ideas in the case (we split this data set in two to try out the modus operandi first).</p> </li> <li> <p>Result-total: Combines the Result-50 and the Result-195 sheet. Colored cells indicate that we marked the idea to be considered to present verbatim in the paper. </p> </li> <li> <p>Kappa-scores: Calculates the Kappa-scores that are presented in the paper.</p> </li> </ul> <p><strong>Dataset-SSys.xlsx and Dataset-VSys.xlsx</strong></p> <p><strong>This file contains all data for respectively the S-Sys and V-Sys cases. The following tabs are present:</strong></p> <ul> <li> <p>Raw data: consists of the raw data collected in the CrowdRE platform of the case. As can be seen, some data is ‘not published’ (but was analyzed in the study and read by both researchers and therefore just redacted in the online appendix), and some data is ‘classified’ (and therefore not analyzed by both researchers as one researcher was not allowed to review the data). The classified ideas should be considered as non-existent in the rest of the data set. </p> </li> <li> <p>Automatically translated data, readability scores: These files are compiled in the same way as in the Tournify case.</p> </li> <li> <p>Vagueness: This file is compiled in the same way as in the Tournify case, although we do provide a small explanation that describes a part of the idea to show why a true or false positive was indicated.</p> </li> <li> <p>Tagging: The tagging of the QUS-framework and ISO/IEC 25010 was done here. As we did this in person, the small discussion held when discrepancies occurred is not presented in the file. The colored cells indicate ideas we considered for verbatim publication in the paper. The colors indicate why we want to publish a certain idea (for example, because it has all QUS-violations).</p> </li> <li> <p>Kappa-scores: This shows the kappa scores and the discrepancies between the individual tagging. This is indicated in colors. </p> </li> </ul> <p><strong>Graphs_readability.aspx</strong></p> <p>This file was used to construct the graphs as presented in figures six and seven in the paper. For this, the readability scores of the three data sets were combined in one tab (one for Flesch and one for ARI) and used in a boxplot.</p> <p><strong>CREUS-pdd.drawio</strong></p> <p>This is the source file for the PDD presented in the paper.</p> <p><strong>Python scripts</strong></p> <p>Two Jupyter notebooks that "S-Sys V-Sys.ipynb" and "Tournify.ipynb" that we used to calculate the readability scores and to identify the vague words. As the data sets were structured a bit differently, the scripts are a bit different between the three cases. In the Tournify case, the script and the output are both present in the Jupyter notebook. For the S-Sys and V-Sys cases, we do include the script but omit the output due to confidentiality.</p> <p><strong>Note:</strong></p> <p>The data sets are included in our paper to allow readers to explore the data themselves. Please contact the corresponding author if you wish to use the data set for other reasons to obtain an explicit permission, since these user stories should be analyzed with proper domain knowledge in order to draw meaningful conclusions.</p>

Replacing Mineral Fertilisers for Bio-Based Fertilisers in Potato Growing on Sandy Soil: A Case Study
<p>The refinement level of bio-based fertilisers (BBFs) can influence environmental and agronomic performance. This study analyses the environmental and agronomic effect of different BBFs on potato growing in sandy soil. A less refined product (liquid fraction of digestate (LFD)), two refined products (ammonium sulphate (AS) and potassium concentrate (KC)), and mineral fertilizer (MF) are compared by conducting: (i) a nitrogen (N) incubation experiment where the N release rate of the BBFs is determined, (ii) a greenhouse gas emission experiment where N<sub>2</sub>O, CO<sub>2</sub>, and CH<sub>4</sub> emissions after BBF application are measured, (iii) a pot experiment where the nutrient fertiliser replacement value (NFRV) of the BBF is calculated, and (iv) a full-scale field trial where the potato quality and quantity and the remaining N residues in the soil after harvest are assessed. The N release rate and the NFRV of AS (142 ± 19% and 1.13, respectively) was higher compared with the LFD (113 ± 24% and 1.04) and MF (105 ± 16% and 1.00). Lowest N<sub>2</sub>O emissions were observed after the application of the less refined product (0.02 ± 0.01 per 100 g N applied) and highest for MF urea (0.11 ± 0.02 per 100 g N applied). In the full-scale field trial, no significant difference in potato yield was observed in the plots that received manure in combination with BBF or MF. This study showed that all three BBFs can safely be used in potato growing on sandy soils. However, the adoption of BBFs can be stimulated by (i) solving the practical issues that occurred during the application of LFD, (ii) making sure BBFs are on the list of RENURE materials so they can legally replace mineral fertiliser, and (iii) reducing the surplus of slurry manure to stimulate the use and fair pricing of BBF products.</p>
An insect-pollinated species in a wind-pollinated genus: case study of the endemic plant, Laramie chickensage (Artemisia simplex)
<p><em>Artemisia simplex</em><span> (Laramie chickensage) is an imperiled, endemic plant in southeastern Wyoming, USA. To fill critical information gaps, we measured its seed viability and pollination mechanisms, measures that are lacking for many rare and endemic plants yet critical for the perpetuation of species. </span><em>Artemisia simplex</em><span> cover varied among sites and occupied 5.5% (range: 1.3–14.6%) of the area on average. This unique plant typically produced viable seeds under ambient conditions but did not self-pollinate. Characteristics of the flower and pollen suggest that </span><em>A. simplex</em><span> is primarily animal-pollinated, and we found that both wind and animals transported pollen to the plant, but wind alone produced fewer seeds.
