Scientifically, araneae is a joint effort of the arachnological community, it is non-profit and its usage is for free. However, besides all the voluntary support, we need a minimum of continuous technical support. We receive financial support by a few institutions indicated in the Sponsor section below but need also your donation. If you want to make a donation to araneae, you can use the "Donate by PayPal" below or you can contact Wolfgang Nentwig.
Technically, araneae can be seen as a project housed at the University of Bern, Switzerland. Your donation will be administered by the University of Bern, a tax-exempt non-profit organization. When you contact us, you will receive a confirmation and you can deduct your donation in your tax declaration.
