Main research findings

We are currently facing catastrophic biodiversity loss. Understanding what causes changes in biodiversity is important for its conservation. Trace DNA in environmental settings such as water, soil or faeces, allows for species detection and monitoring without the need to sight the actual organisms. Particularly environmental DNA metabarcoding proves a useful tool for the simultaneous identification of many organisms in an environmental sample. However, interpretations of the results can be complex, especially in interdisciplinary contexts requiring multiple lines of evidence.

This thesis aims to untangle this complexity by combining environmental DNA metabarcoding with different kinds of data using a diversity of statistical and data visualization approaches. The work focuses on DNA from modern and ancient faeces and sediments for dietary reconstructions as well as human-environment interactions. Different topics are addressed, i.e. biomonitoring of herbivores in a wildlife reserve in India, reconstructing the diets and habitats of Pleistocene megafauna, reconstructing prehistoric human plant use, and untangling human-environment interactions in southeast Norway during the Holocene. This work illustrates that the combination of DNA metabarcoding of ancient and modern environmental records with other lines of evidence can provide unprecedented insight into past and present biodiversity, including biological interactions, effects of climate change and human activities.
