Summary of Results

 

Highlights:

 

  1. Ecological effects of low levels of POPs demonstrated in seabirds suffering from multiple stressors such as food shortage

  2. DNA damage of POPs through shortening of telomeres shown in  kittiwakes

  3. Arctic skuas wintering in the Southern Ocean are carriers of persistent pollutants to the Arctic 

 

Seabirds are among the species most vulnerable to bio-magnifying environmental contaminants, and the main objective of this project is to document concentrations, distributions and effects of different environmental contaminants in northern seabird populations.  Special focus is on how environmental contaminants may function in concert with other natural and anthropogenic stressors; i.e. a multi-stress perspective.  

 

The project project studies different seabird species at Kongsfjorden, Svalbard. Prime species of interest are the common eider, the kittiwake, the glaucous gull, and skuas (great skua and arctic skua). These species represent different food chains (benthic, pelagic and scavenging). In 2016 new data have been collected for kittiwake, eiders and glaucous gulls and arctic skuas from Kongsfjorden in Svalbard.  The project is linked to the NFR project AVITOX which has received funding in 2014-2016. 

 

For kittiwakes data have been collected from a study colony in Kongsfjord; in 2016 for the 10’th year in a row.  All blood samples from kittiwakes collected between 2007 and 2011 (5 years) have been analyzed and the variation in concentrations of POPs in live kittiwakes over time, and thus the potential effects of POPs, is studied. Great annual variation in legacy POPs in kittiwakes was demonstrated. One paper has been published online in 2016 (Bustnes et al. in 2016). Within the multistress seabird project, a cooperation with the Olivier Chastel Group has resulted in 2 papers published in 2016. Among these studies, we will particularly mention the finding that shortening of telomeres was most profound in birds with high concentrations of oxychlordane, a very toxic metabolite of chlordane (Blevin et al. 2016). In 2016, Olivier Chastel’s group has continued research on kittiwakes in Kongsfjorden, focusing especially on potential effects of POPs on sperm quality. The material collected are now being analysed, both with regard to effects of POPs by the PhD student Pierre Blevin who will work in  Tromsø in the fall 2016 to complete POP analyses. Moreover, a paper has been published showing that the preen gland is an important excretion route for POPs in kittiwakes (Solheim et al. 2016). 

 

For the great skua, the Flagship funding has enabled continuous work using data from the NFR funded SKUA project. Two papers are now being prepared for publication; one on the effect of remoteness and cold condensation on legacy contaminants in great skua across the Northeast Atlantic (Leat et al. in prep a), and one on the effect of diet on the accumulation of POPs (Leat et al. in prep b). 

 

The master student on arctic skuas (Elise Skottene) finished her thesis in spring 2015.  The thesis was about wintering areas and heavy metals in blood and feathers. In addition, blood samples have been taken from a large number of arctic skuas that have been equipped with GLS loggers. The POP analyses of these birds are almost completed.  Preliminary results indicates that these birds carry contaminants from their wintering grounds in the southern Ocean to the Arctic (Hanssen et al. in prep).  

 

The studies of common eiders has progressed and Anette Fenstad, with whom Mutistress/AVITOX has cooperated closely, defended her PhD in June 2016 (J.O. Bustnes has been a supervisor for her thesis). In 2016, papers have been published/accepted for publication ( Fenstad et al. 2016, in press a, b, c).  Eiders in the Baltic Sea had up to 26 times higher blood concentrations of some POPs compared to eiders from Svalbard. In addition, individuals with high levels of POPs/metals are more prone to suffer higher oxidative stress (OS) (Fenstad et al. 2016).  Moreover, paper on the impact of PCB/Hg on DNA double strand-breaks is being prepared (Fenstad et al. in press b). Finally, a paper on migration strategies of common eiders have been accepted (Hanssen et al. in press). 

 

Modelling exercises have been carried out for common eiders by Bård-Jørgen Bårdsen, which has the aim to understand the potential impact that POPs have in causing ecological effects in this species. A paper is now being prepared for submission in 2017 (Bårdsen et al. in prep). 

 

Finally, Ane Haarr defended her MSc thesis on  gentox in several arctic seabird species and is now at the stage of writing up the thesis to a publication.

For the Management

 

Environmental contaminants have been of concern for management for many decades, and this project adds knowledge to how such pollutants can have adverse effects even as concentrations are declining.

Conclusions

 

  1. Understanding variation and impacts of POPs in the vulnerable ecosystems of the north is a long-term endeavor. In this respect this project is important because it allows us to have a long horizon on our research. The project is now starting to generate new results, both with regard to trends and effects of POPs that is novel to ecotoxicology.
