European Arachnid Biodiversity Research

Since 2014, the Society has supported biodiversity research in a specific country or region within Europe following relevant calls.

Members who are working on biodiversity and like to tackle a specific goal within the scope of two years are encouraged to send an application including a research plan (max 2 pages) to the ESA Council ( until May 31. 2024. Please note that we have expanded this call to include all Arachnids, and not only spiders.

The Society provides support as to consumables and offers a platform for promoting biodiversity research and increasing its visibility.

2022/23 – Kosovo

The project was awarded to Donard Geci for support in faunistic work on the spider fauna of Kosovo.

ESA support:

  • ESA as platform for increased visibility
  • Media outreach
  • Support with consumables

The main objective of this project is to investigate the fauna of spiders, distribution and rare species in the Republic of Kosovo, including special ecosystems such as caves, and to assess the impact of environmental factors on the distribution and subscription of spiders in different habitats.

2014/15 – Greece

In 2014/15, the first European Year of Spider Biodiversity Research is devoted to Greece, one of the most important biodiversity hotspots of Europe. We ask all interested arachnologists to perform collections in Greece, share material, contribute new records, and help with identifications.
