2018 Daniel HitchcockDaniel's PhD thesis is titled "Life history and pollutant accumulation and wildlife". He was interested in how variation in life-history affects contaminant levels in different species. For example, how do animals allocate energy toward reproduction? How does this affect contaminant levels? What differences do we see between males and females? Daniel investigated reproductive strategy in marine mammals (seals, sea lions and walruses) and compared pollutant levels between mothers and pups. He also looked at maternal investement in seabirds and compared males and females. Lastly, he conducted a field study on barnacle geese (Branta leucopsis), investigating the effects of migration strategies on pollution in eggs. Daniel is an Australian who undertook his Bachelor degree at the University of Melbourne and Master degree at the University of Bergen. Daniel's supervisors were Katrine Borgå (UiO), Tom Andersen (UiO) and Øystein Varpe (UNIS). |

2019 Clare Andvik (McEnally)
Clare's project was a collaboration with Norwegian Orca Survey and the Norwegian University of Life Sciences. Clare is originally from England, and moved to Norway in 2014. She also completed her bachelors in biology at the University of Oslo. Clare's supervisors were Katrine Borgå (UiO), Eve Jourdain (Norwegian Orca Survey), Anders Ruus (UiO), Jan Ludvig Lyche (NMBU). After her masters, Clare worked as research assistant on a screening project for levels of legacy and emerging contaminants in various whale species along the Norwegian coast, funded by the Climate and Environment department's Arctic 2030 programme. |
2019 Malin Røyset Aarønes
Malin found that clothianidin was taken up in the body and the head (the brain) of the bumblebees, and it seemed to have an effect on nectar consumption and food storing. However, she did not find a change in mortality or reproduction, which could be due to short exposure time. Malin's thesis was a part of the NEOPOLL project, which works to determine the effects of neonicotinoids and temperature on crop pollination. The project was a collaboration between the University in Oslo, the Centre for Agri-Environmental Research in Reading, UK, the NUI Gallway in Irland, and the Norwegian Institute for Water Research (NIVA). Malin's supervisors were Katrine Borgå (UiO), Bert van Bavel (NIVA), Anders Nielsen (UiO), and Julie Sørlie Paus-Knudsen (UiO). After her masters, Malin worked as a research assistant on the NEOPOLL project and Regional Monitoring report for Western Europe. |
2019 Nina Knudtzon
Nina found higher concentrations of lipophillic contaminants in eggs compared to the mother, suggesting maternal transfer. Furthermore she found higher levels of PFAS in the outer fjord gulls, likely due to airport activity. There was a more marine diet and higher trophic niche in outer Oslofjord gulls than in inner Oslofjord gulls. This master project was a part of a bigger project called Urbanfjord, which is a collaboration between the Norwegian Institute of Water Research (NIVA), the Norwegian Institute of Air Research (NILU) and the University of Oslo (UiO). It is funded by the Norwegian Climate and Environmental Agency (Miljødirektoratet). The Urbanfjord project monitors pollution status of the marine food web of the inner Oslofjord. Nina's supervisors were Katrine Borgå(UiO), Anders Ruus (UiO) and Morten Helberg (UiO). |
2019 Helene Thorstensen
Helene compared contaminant levels in the herring gull (Larus argentatus) with the eider duck (Somateria mollissima) to look for differences that could potentially be of importance for monitoring. She found higher levels of contaminants in the marine feeding eider duck than the terrestrially influenced herring gull. However changes could also have been due to breeding ecology and life history traits, and not directly linked to ecological niche. Helene's master project was part of the monitoring project Urbanfjord funded by the Norwegian environmental agency (Miljødirektoratet), and is a cooperation between the Norwegian Institute for Water Research (NIVA), the Norwegian Institute for Air Research (NILU) and the University of Oslo (UiO). The Urbanfjord project monitors pollution status of the marine food web of the inner Oslofjord. Her supervisors were Katrine Borgå(UiO), Anders Ruus (UiO) and Morten Helberg (UiO). After her masters, Helene worked as a research assistant on several projects including Urbanfjord, NEOPOLL and Nansen Legacy. |
2019 Emelie Skogsberg
Her thesis was a part of a bigger project called TerrACE, which is a collaboration between several Norwegian and North American partner institutes. The TerrACE project stands for ”Effects of terrestrial inputs on contaminant dynamics in Arctic coastal ecosystems”. Therefore, this project focuses on climate change mediated effects, such as terrestrial runoffs, resulting in contaminant remission from land, contaminant uptake, accumulation and food web transfer in coastal biota, occurring at the land-sea interface. Emelie's supervisors were Katrine Borgå (UiO) and Øystein Varpe (UNIS). |
2019 Laura Andrea Alfaro GarciaLaura's master thesis is titled "PFAS bioaccumulation in Antarctic breeding south polar skua (Catharacta maccormicki) and its prey items". Laura compared the occurence of PFAS in two Antarctic populations of south polar skua: Svarthammeren and Dumont d'Urville. She compared the avian food webs at the two breeding colonies tried to determine whether differences in PFAS exposure were due to diet during the breeding period in the continent or if it was produced by other factors. The food web at Svarthamaren, which included south polar skuas, Antarctic petrels, fish and krill (petrels’ stomach content), had detectable concentrations of PFAS in bird tissue but not in stomach content. The food web at Dumont d’Urville, which included south polar skuas and Adélie penguins, had considerably lower concentrations of PFAS compared to Svarthamaren. This master thesis was a part of POLAR ECOTOX project nr 243763/E50, financed by the Research Council of Norway (Norsk Forskningsråd). Supervisors were Katrine Borgå (UiO), Dorte Herzke (NILU), Jan Ove Bustnes (NINA) and Geir Wing Gabrielsen (NPI). |
2018 Vivaine Girardin
Road and tunnel wash runoff contain a variety of organic and inorganic compounds with the potential to contaminate natural aquatic environments. An efficient, low-cost measure used to protect these waters is the construction of artificial sedimentation ponds. They are constructed in strategic places in order to capture the runoff, consequently protecting natural water bodies from highly contaminated discharge. These ponds eventually become home to a variety of aquatic organisms that will be exposed to high amounts of contaminants. Dragonflies are of special interest because they have both terrestrial (adult) and aquatic (larval) life stages, and are carnivores in the middle of the food chain. Due to their aquatic life stage, dragonflies are also potential contaminant vectors from the aquatic to the terrestrial environment. This study was a part of the project Reducing Highway Runoff Pollution (REHIRUP) within the Nordic Research Program (NordFoU), funded by the Danish, Norwegian, and Swedish National Road Administrations (NRAs). The Norwegian Institute of Water Research (NIVA), and University of Oslo are contributors to this project. Supervisors were Merete Grung (NIVA/UiO), Katrine Borgå (UiO) and Sondre Meland (NIVA) |

2017 Ellen Kristine KeilenEllen's master thesis is titled "Levels and effects of environmental contaminants in herring gull (Larus argentatus) from an urban and a rural colony in Norway". Supervisors were Katrine Borgå (UiO) and Ketil Hylland (UiO). |
2017 Cathrine HoelCathrine's master thesis is titled "Lower food web mercury dynamics in two contrasting boreal lakes – a seasonal study". She was interested in better understanding driving factors in the transport, bioavailability, uptake and transfer of mercury in boreal lake food webs, with the focus at the base of the food web. There has been an increasing trend in mercury concentration found in fish in many regions in northern lake ecosystems. The mercury cycle will lead to the mercury emission ending up in the cold northern areas, where it will bind to dissolve organic carbon (DOC) and may accumulate in biota. Climate change may enhance the mobility of mercury by increasing the deposition of DOC to surface waters and hence the associated mercury. Trying to get a better understanding of the driving factors, Catrhine conducted an intense and detailed study at the base of the food web, including bacteria, primary producers and zooplankton. Water and biota samples were taken from two different lakes with contrasting levels of DOC, one clear water and one humus-rich lake. This took place over the course of spring, summer and fall of 2016. Supervisors were Katrine Borgå (UiO), Amanda Poste (NIVA) and Tom Andersen (UiO). |
