Tittel

Next-generation biodiversity assessment

Populærvitenskapelig sammendrag

Marine sediments constitute the largest single ecosystem on earth and their communities of benthic organisms significantly influence major ecological processes. Current marine management policies are strictly based on the maintenance of biological diversity, but our knowledge of marine benthos is lacking, especially in the deep sea and at higher latitudes. There is also an urgent need to monitor benthic biodiversity in the face of human impact and environmental change. The current project specifically focuses on the demand for cost effective and representative monitoring of benthic organisms in locations of particular concern, as a basis for sustainable ecosystem management. Traditional methods for identification of benthic organisms are exceedingly labour-intensive and time-consuming, and therefore, expensive. In addition, biodiversity assessments require extensive expertise, and are capable of examining only a fraction of the existing biodiversity. DNA based methods offer a possible solution to these shortcomings. The current project applies next-generation DNA sequencing and barcoding to analyse the communities of benthic organisms from sediment samples. The project will contribute to development of coherent methods for biodiversity assessment and monitoring. We are analysing sediments influenced by aquaculture and oil production. In addition, the project will expand our knowledge in general of benthic biodiversity in boreal waters.

Vitenskapelig sammendrag

There is a need to expand our knowledge of marine ecosystems in north Norwegian waters. This project specifically focuses on the demand for cost effective and representative mapping and monitoring of benthic communities in habitat types of particular concern, as a basis for sustainable ecosystem management. Marine sedimentary habitats constitute large ecosystems worldwide and their benthic communities significantly influence major ecological processes, such as geochemical cycling, secondary production, pollutant distributions, and stability of sediments. Current marine management policies are strictly based on the maintenance of biological diversity, but our knowledge of marine benthos is lacking in geographic range, especially in the deep sea and at higher latitudes. In addition, there is an urgent need to monitor marine ecosystems in the face of environmental change.
Traditional methods for identification of benthic organisms are exceedingly labour-intensive and time-consuming, and therefore, expensive. Also, diversity assessments require extensive taxonomic expertise, and are usually limited to a part of the existing biodiversity, typically the macro fraction of the biota. As a result, there is an obvious mismatch between the need for representative biodiversity assessments and the resources at hand. DNA based methods offer the beginning of a possible solution to these shortcomings. The current project applies DNA barcoding and high-throughput sequencing technologies to analyze the benthic communities from bulk sediment samples, from a natural depth gradient in a fjord basin, and from environments influenced by aquaculture and oil production. We will further contribute to holistic and coherent methods for biodiversity assessment and monitoring. We aim to significantly expand our knowledge on the benthic biodiversity in boreal waters and contribute to molecular reference databases, in particular focusing on an important taxonomic group, the marine nematodes.
