Atlas of the European Arachnids
Atlas of the European Arachnids
(Arachnida: Araneae, Opiliones, Pseudoscorpiones, Amblypygi, Solifugae, Scorpiones, Schizomida)
The Atlas of the European Arachnids (formerly Recording Scheme of the AraGes) is an unsystematic but continuously updated collection of records (occurrences) of arachnid species (excluding mites) in central Europe (while not excluding surrounding regions). The Atlas is based on the records previously assembled by Aloysius Staudt, recording species occurrences per topographic map 1:25,000 and per decade (two larger periods before 1950). The new Atlas presents these and future records with a higher spatial and temporal resolution and with additional details which allow new useful analyses of the records. The database contains about 300,000 records for more than 530,000 individuals as well as 1177 recorded species from more than 5600 known species of the treated orders (as of August 2016). New records, new details and corrections are always welcome. They can be submitted in free form on the page (http://atlas.arages.de/writemessage) or via your own user account (register at http://atlas.arages.de/register).
The new Atlas is implemented as a multi-user system. Regular contributors can enter new records via their own user account. A board of editors verifies new records and ensures a high quality of new records. Taxonomists update the species and families known to the system according to the latest taxonomic changes.
The Atlas is available in German and English language and thus simplifies research by interested parties from neighbouring countries.
The Atlas site contains various tools:

- Frequency lists: http://atlas.arages.de/frequencies
- Recording status in individual countries or regions (e.g. Bundesländer): http://atlas.arages.de/recordingstatus
- List of included record sources (published, unpublished, individual reports or databases and collections): http://atlas.arages.de/allsources
- List of recorded species in individual countries or regions: http://atlas.arages.de/checklist
- List of missing species (species not recorded for a long time): http://atlas.arages.de/missingspecies

Tools of specific record maps
Each record map contains various tools:
- Presentation of localities on scaling maps by Google, OpenStreetmap etc.
- Locations are aggregated to TKs (in Germany) or displayed in higher detail, depending on zoom level
- The decades of the most recent record at a location can be displayed in different colours
- Flexible printing function of selected regions with various map backgrounds for your own papers
- Links to other online resources, e.g. World Spider Catalog, araneae, AraGes Wiki, recording schemes of BeNeLux countries, Britain and Czech Republic
- List of record sources
- Statistics regarding gender, maturity, collection method, identification characteristics, biotope type as well as phenology
