A literature study of human activities and pressures as well as ecosystem component layers available for Marine Spatial Planning and mapping of cumulative impacts in Swedish marine waters
Andersen, Jesper Harbo; Kallenbach, Emilie (NIVA-rapport;6997, Research report, 2016)We report a literature study on the needs for and the availability of data layers required for evidence-based Marine Spatial Planning (MSP) as well as mapping of the potential cumulative effects of multiple human activities. ... -
Anthropogenically impacted lake catchments in Denmark reveal low microplastic pollution
Kallenbach, Emilie; Friberg, Nikolai; Lusher, Amy; Jacobsen, Dean; Hurley, Rachel (Peer reviewed; Journal article, 2022)Microplastics have been detected in lake environments globally, including in remote regions. Agricultural and populated areas are known to congregate several inputs and release pathways for microplastic. This study ... -

Chitinase digestion for the analysis of microplastics in chitinaceous organisms using the terrestrial isopod Oniscus asellus L. as a model organism
Kallenbach, Emilie; Hurley, Rachel; Lusher, Amy; Friberg, Nikolai (Peer reviewed; Journal article, 2021)Chitinaceous organisms have been found to ingest microplastic; however, a standardised, validated, and time- and cost-efficient method for dissolving these organisms without affecting microplastic particles is still required. ... -

(NIVA-rapport;7204, Research report, 2018)The MONIS 3 project reports the development of 22 species-specific eDNA-based test systems for monitoring and mapping of the occurrence of non-indigenous species in Danish marine waters. The development has been undertaken ... -
Early ecosystem responses to watershed restoration along a headwater stream
Kallenbach, Emilie; Sand-Jensen, Kaj; Morsing, Jonas; Martinsen, Kenneth Thorø; Kragh, Theis; Raulund-Rasmussen, Karsten; Baastrup-spohr, Lars (Journal article; Peer reviewed, 2018)Along many streams, natural riparian vegetation has been replaced by agricultural fields or plantations resulting in ecosystem alterations due to changes of the interactions across the land-water ecotone. We studied the ... -
