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 first field trip in EBAI was held August 10-11 and went to the Atna watershed and the Rondane Mountains. Three stations, Vollen, Dørålseter and Skranglehaugan, were sampled for benthic invertebrates while eDNA from water was sampled at Dørålseter. We also got to test our mobile water filtering setup for the first time. Very successful!
