Based on the results from this thesis, this will most likely lead to loss of soil C, which ultimately may affect the global C cycle. If the rise in forest lines continues, a corresponding shift in fungal communities will take place. The predominance of ectomycorrhizal and saprotrophic fungi below the forest line may contribute to enhanced C turnover, while the predominance of root-associated ascomycetes above the forest line, of which many have melanized mycelia, may promote a slower C turnover and increased C sequestration here. Further, soil C and ergosterol showed a strong increase towards the low-alpine vegetation. On the contrary, there were relatively higher abundance of ascomycetes, including archaeorhizomycetes, ericoid mycorrhizal fungi and dark septate endophytes above the forest line. There were relative higher abundance of basidiomycetes and mucoromycetes, including ectomycorrhizal and saprotrophic fungi, below the forest line. Regardless of site, there was a strong gradient in community composition across the ecotone, acknowledging the ecotone as the primary structuring gradient shaping the biota in soil. The sensor gathers data across the entire visible colour spectrum and the near infrared (380-750nm with possibilities for further adjustments). : a transition area between two adjacent ecological communities ecotonal -k-t-nl e-k- adjective Did you know Every modification of climate, every disturbance of the soil, every interference with the existing vegetation of an area, favours some species at the expense of others. Compositional changes in the belowground biota were analyzed using DNA metabarcoding of the rDNA 18S and ITS2 markers, while ergosterol was used to quantify changes in fungal biomass. Our UHI sensor makes it possible to collect and process hyperspectral light underwater, opening up a whole new world of subsea remote monitoring. History has shown us that it takes a team of shared knowledge and experiences to bring life. We appreciate that talent comes in many forms and from several different schools of thought. We hire positive, self-starting individuals who are stewards for the environment. From nine different sites, soil samples were obtained along 200 m transects stretching from subalpine mountain birch forest to low-alpine vegetation. Ecotone’s success is driven by our employees. The results are seen in light of soil C sequestration processes. The aim of this MSc thesis was to analyze compositional chances in the soil biota across the mountain birch forest line ecotone, with a main emphasis on fungi, as well as their environmental drivers. As the soil C dynamics primarily is regulated by belowground microorganisms, a better understanding of these communities in a changing climate is crucial. A large fraction of earths terrestrial carbon (C) are stored in the soils of these northern ecosystems. One consequence of global warming in Norway is an upward shift in the mountain birch forest line.

The hyperspectral images can be analyzed using the software of your choice. The UHI sensor is delivered with the software Immersion, for live view, contorol and data recording – as well as functionality for calibrating and geo-referencing the raw hyperspectral images. It can also be mounted and used on other devices used for underwater inspection and mapping. The sensor is mounted with a clear field of vision to the seabed and flanked by dedicated SpectraLux subsea lights, registering data as the vehicle moves. The hyperspectral sensor we supply can be integrated with most modern ROV systems using standard industry couplings and cables. Worldwide it had approx 2,000 employees at the end of 2011, a year in which it reported a revenue of 706 million. It has operations in Europe and North America. The sensor gathers data across the entire visible colour spectrum and the near infrared (380-750nm – with possibilities for further adjustments). Ecotone (formerly Royal Wessanen) is a multinational food company with a focus on organic, founded in the Netherlands and headquartered in France since November 2020. Our UHI sensor makes it possible to collect and process hyperspectral light underwater, opening up a whole new world of subsea remote monitoring. Scientific UHI (Underwater hyperspectral Imager) Ocean Vision.UHI technology is perfect for identifying, classifying and monitoring materials on the seabed. Ecotone delivers modern solutions for identification, monitoring and mapping of seabed features and marine installations. We supply our patented technology UHI (Underwater hyperspectral imager) together with software Immersion and subsea lights SpectraLux for research, industry and other marine applications.
