What will happen with the eDNA of lake fauna when much of the animal life is eradicated? We suspect that it will increase as the dead animals dissolve and then decrease to a level below that before rotenone treatment, but we don't know for sure. Previous studies also show that macroinvertebrates in lakes are less susceptible to the rotenone poison than fauna in running water. Thus, we do expect a many species and perhaps species groups to do survive the treatment.<\/p>\n

What will happen to these populations when the benthic community is altered and all fish is gone? We will follow up with eDNA sampling through EBAI and compare results with those of traditional benthic kick-sampling at the exact same sites.<\/p>\n

This week, a journalist and photographer\u00a0from\u00a0NRK - the national public broadcaster -\u00a0joined us in the field. Their report can be viewed here: \"Ny metode for vannoverv\u00e5kning<\/a>\".<\/p>\n
