Méthodes d'échantillonnage
We extracted the information from herbarium labels. Most records have modified names of taxa in case they have corresponding names in the GBIF Backbone Taxonomy or other nomenclature checklists available in the GBIF (e.g. Lejeunia spp. that is mentioned in the labels we fixed into Lejeunea spp.). Nevertheless, some nomenclature names were given according to the original names given on labels. The dataset contains the original descriptions (in German, Latin, French etc.) of the locality and the modified descriptions in English. We determined the geographical coordinates of each record based on the locality description. We used open sources (Google Maps, Google Earth, OpenStreet Map, the images of old maps etc.) to find the approximate locality where the specimens were collected. However, some labels have no enough information to find even an approximate locality so these records contain information about the country of the gatherings only.
| Etendue de l'étude | The dataset contains the records of the specimens collected from Europe in the Middle of the 19th century. Most specimens were gathered from the territory of modern Germany, Austria, Italy, Denmark, Sweden, and so on. |

| Contrôle qualité | Data quality control was provided using some tools that fix different types of mistakes. We fix the mechanical mistakes in OpenRefine and taxonomical mistakes in integrated to the GBIF Species matching tool. |
Description des étapes de la méthode:
- 1. Creating the spreadsheet in GoogleSheets. It is a useful method to make the row database in different places, on different devices, at any time. 2. To determine what kind of fields and how to give names to them correctly, we used information from the GBIF's webpage 'Data quality requirements: Occurrence datasets' (https://www.gbif.org/uk/data-quality-requirements-occurrences) and Darwin Core Quick Reference Guide (https://dwc.tdwg.org/terms/#resourcerelationship). 3. Based on information from herbarium labels, we filled the fields for each herbarium specimen. 4. Each specimen was scanned and images were downloaded to cloud storage. 5. The links to images must be added to the field with a corresponding record. 6. Download the spreadsheet with the database in .csv format. 7. Upload the spreadsheet (.csv file) to OpenRefine for data cleaning. 8. Data cleaning includes some steps. E.g. delete excessive whitespaces at the beginning and the end of a word and between words. Conjunctive similar words into one correct value. Faceting the dates and coordinates. 9. Checking the correspondence of the nomenclature names with the GBIF Backbone Taxonomy (https://www.gbif.org/tools/species-lookup) and fixing the mistakes in the taxonomy.
