Dorolseter-Rondane

The Nedre Dørålseter cabin next to the Rondane National Park in Central Norway. Not a bad place to do field work on a day like this!

In year two of field work for the EBAI-project, we have focused on eDNA and benthic samples at three different stations along the River Atna. By filtering water and analysing DNA from bulk extractions, we want to see how different the diversity of freshwater invertebrates is between stations and if both methods retrieve the same species. As usual, we filtered our water in the field and fixed our 4 min kick samples on ethanol.

The second field-sampling trip in EBAI was directed to the Lake Jonsvatn on September 28. We sampled a depth gradient (0.25 m, 2 m, 7.5 m and 15 m) for benthic invertebrates starting from Trondhjems Roklub, and eDNA from water from the Roklub pier. Also, adult flying insects were sampled with a net. Weather conditions were perfect during the second successful field trip, and in addition to the samples, we got nice pictures including the spectacular panorama photo on top of the page.
