Summary of Results

The project had its start in January 2016 with a user panel meeting (cf. The Strategic Foresight protocol) where all the researchers in the project, end-users and stakeholders met to disuss what should be the focus of the research witthin the project. This meeting initiated the contact between the different interest-groups within the different focal case-studies in the project, which spearheaded further discussions and meetings throughout 2016-2018. This has ended up in agreed-upon focus for the scientific work, such that it's focus has relevance for end-users and stakeholders in the future. The additional funding that the project recieved from FRAM ensured that researchers from NINA in Tromsø could attend these meetings as well as be activly involved in the ongoing discussions, analyses and writing of scientific publications. This has been vital, given their long-term reseach and knowledge with regards to reindeer husbandry in Norway (Reindeer case study), one of the main end-users/stakholders in the project, as well as Auduns long-term research and knowledge from Svalbard in the high-arctic (Svalbard case study). 

Both have also been vital actors in the work on the evaluation of management actions implemented to change the fate of endangered Lesser white-fronted goose in Norway. This work has shown that the increase in the population of geese in Finnmark after the red fox decimation program was initiated, is not likely due to the management action, but due to indirect food web interactions with small rodents and availability for predators of reindeer carcasses, both of which has increased the last decade. This work highlights the importance of a proper evaluation of management actions, by assessing possible other drivers of change (food web approach).

Both researchers have also been part of the work on drivers of change in willow ptarmigan dynamics the last decades. This work show that the population growth rate of ptarmigan has decreased since the start of the millenium (2000). By adopting a food web approach, we have shown that climate change act on ptarmigan both directly (local climate) and indirectly (through small rodents, carcassess and predators). One of the strongest drivers have been the effect of delayed onset of winter, likely leading to higher predation pressure on ptarmigan due to a mismatch in plumage color and snow cover. 

Master and PhD-students involved in the project

Budget in accordance to results

All the funding has been used on the vital participation of the two NINA researchers, as planned.

The additional funding from the FRAM centre has assured the crucial involvement and participation of two researchers at NINA in Tromsø, i.e. Torkild Tveraa and Audun Stian, costs which was not included in the project financed by the NRC. Flagship funding have therefore complemented the funding from NRC and assured that the researchers from NINA have had some research time and mental involment devoted to the project.

Could results from the project be subject for any commercial utilization
No
Conclusions

The additional funding that the project recieved from FRAM ensured that researchers from NINA in Tromsø could attend meetings and be activly involved in the ongoing discussions and evolution of the projects fokus. Lately their involvment in the analyses and writing of scientific publications have been a vital contribution to the project.. This has been vital, given their long-term reseach and knowledge with regards to reindeer husbandry in Norway, one of the main end-users/stakholders in the project, as well as Auduns long-term research and knowledge from Svalbard in the high-arctic.
