DNA and Life – a national citizen science project using eDNA to monitor invasive, rare and endangered species in Danish aquatic ecosystems.

Listed in GBIF

DNA and Life is a national research and citizen science project at the Natural History Museum of Denmark under Copenhagen University.

Description

The project has had many branches throughout the project period, including the currently active ‘DNA på Forkant’ (DNA in advance) which is in collaboration with ‘Foreningen af Danske Biologer” (the association of Danish biologist). The project uses eDNA and citizen science efforts to monitor the distribution and occurrence of specific aquatic species in Denmark.

We have a special focus and rare, invasive, toxic and endangered species. Danish high school students collect water samples all over the country and send them to one of our DNA-labs for extraction of DNA. The students may also participate in the laboratory work and prepare their sample for qPCR.

The presence of each target species is investigated by at least two groups of students. The students prepare both positive and negative controls while preparing the eDNA samples. To ensure data quality, species replicas where the negative control exceeds the threshold (Higher than 41 CT) or the positive control does not exceed the threshold (lower than 41 CT), are discarded.

This means that if a species occurrence is noted as ‘Present’ in our Dataset at least one of the student groups working with said species had a functional positive control, a negative control which was not contaminated and a CT-value below 41 for their eDNA sample.
