New features on these pages include:

• A Commented Checklist of the Spider Species (Araneae) in the Caucasus Ecoregion (also available as PDF),
• Redesigned species datasheets with new record maps, information on altitudinal distribution and abundance status,
• The new Genus pages listing all species within a genus according to their abundance and with links to the pages of Araneae – Spiders of Europe. This feature should make determination somewhat easier,
• A record density plot (see above) showing relatively well visited regions and regions with few or no spider records at all (gray and white areas in the plot). More information on spider diversity patterns is given in the pages on landscape & habitat diversity and species diversity patterns.
