16 years of river restoration : effects of restoration measures on macroinvertebrates and salmonids in Bognelv, Northern Norway
Kivle, Dina Emilie Norum; Schmitz, Sunniva Buvarp (Master thesis, 2022)Lotic ecosystems worldwide are being degraded by human activities, with severe consequences for stream biota. River restoration has gained momentum over the last decade, but many projects lack the long-term monitoring ... -
Cod on the dive : investigating Atlantic cod of the Inner Oslofjord during population decline
Craig, David Charles (Master thesis, 2021)The Atlantic Cod population of the Inner Oslofjord is in the midst of a collapse and a catch ban has been in effect since 2019. This project was designed to study demography, population size and migration in the Atlantic ... -
Determinants of habitat utilization patterns of European lobsters (Homarus gammarus) in the Inner Oslo Fjord, Norway
Teyie, Sharon (Master thesis, 2022)Habitat type and structure influences diversity body size, recruitment, population size structure and survival of species in marine communities. There is, however, inadequate empirical evidence on what substitutes ... -
Establishing a biodiverse meadow roof in Oslo, Norway : an evaluation of the effect of soil type and soil depth on sown native and local species and spontaneously colonizing species
Berge, Turid Neby (Master thesis, 2020)The loss of biodiversity is happening faster now than ever in human history, being mainly driven by changes in land use. Concurrently, cities are expanding and are expected to reach over 1.2 million km2 within 2030. The ... -
Facilitating migration for anadromous salmonids through restoration and compensation : challenges and opportunities
Falk, Marianne-Isabelle (Master thesis, 2021)Many of the rivers that flow into the inner part of the Oslo fjord have for a long time been subjected to habitat change done to facilitate a growing human population with all the requirements that follow. This has led to ... -
Growing up where you were born : a comparison of nursery areas for salmonids in river stretches with and without natural spawning
Lungrin, Elina (Master thesis, 2020)Ecosystems are significantly impacted by activities from human settlements. This is especially the case for aquatic ecosystems as many large cities sit on coastlines or along major rivers. Species like salmonids are ... -
How to best create or restore wild meadows in an urban setting
Songweh, Thierry Nwokimbe (Master thesis, 2020)Anthropogenic activities associated with increasing influx of people in cities globally and the capital city of Norway, Oslo, has expansively fragment and decreased urban green space, reducing the connectivity between the ... -
A hydrological comparison of drained, pristine, and recently rewetted bogs : early signs of improvement?
Walle, Eirik (Master thesis, 2021)Excavation of drainage ditches over centuries has caused widespread drying and degradation of mires in Norway. The Norwegian government therefore presented an action plan in 2016 for restoring mires by blocking these ... -
Insect community response to recent rewetting of drained bogs in Southeastern Norway
Utseth, Hanna (Master thesis, 2021)During the last five years, Norway has rewetted almost 80 drained mires to reduce climate emissions, limit the risk of natural disasters, and to prevent further loss of biodiversity. Even more mires are planned to be ... -
Lesser sandeel (Ammodytes marinus) in the Tana river delta : temporal variation in abundance, habitat use and demography
Sevedzem, Veronica Nguka (Master thesis, 2019)Lesser sandeel (Ammodytes marinus, Raitt, 1934, sandeel for short) is a keystone species of the Barents Sea ecosystem. However, little is known about the distribution of this species in the Tana fjord or Tana river delta ... -
Responses in fish and macroinvertebrates to channelization and restoration in two Arctic rivers
Lium, Andreas (Master thesis, 2018)The two rivers Salangselva and Kvernmoelva in Troms county, were both channelized and erosion secured during the 1980s. This stimulated agricultural activity in adjacent properties in the following years. In parallel, a ... -
Sea trout in Inner Oslofjorden : population biology, marine recreational fishing and spatial variation in fishing intensity
Vakurov, Mikhail (Master thesis, 2019)Recreational fishing has been known since XV century. Nowadays, Arlinghaus and Cooke (2009) estimate, that around 10,6% of the population in studied countries participate in recreational fishing. However, marine recreational ... -
Short-term effects of a marine sanctuary on the local lobster population in the Oslo fjord, Norway
Vold, Mari (Master thesis, 2022)The European lobster (Homarus gammarus) population in Norway is over-fished and endangered, and marine protected areas (MPAs) are an increasingly utilized measure for protection of this species. Previous studies in Norway ... -
A snapshot of restored bogs in Southeastern Norway : short term vegetation change after rewetting of ombrotrophic mires
Johansen, Aase (Master thesis, 2021)Drained peatlands are affected by altered hydrological conditions. Rewetting by ditch blocking and deforestation is conducted to improve ecological conditions of drained peatlands. This study maps the vegetation communities ... -
Temporal development of macroinvertebrate communities and their responses to restoration measures in Bognelv, Norway
Bjørngaard, Rakel (Master thesis, 2020)Human activities drive degradation and biodiversity loss of freshwater rivers globally. One of the major threats to rivers are channelization, which straightens the river and eliminates the heterogenic habitats as opposed ... -
Vegetasjonsutvikling i løpet av sju år etter revegeteringstiltak langs vegar i Lista vindkraftverk
Nyjordet, Sara Margrete Gilberg (Master thesis, 2020)Etablering av nye vindkraftanlegg medfører ofte utbygging av vegnett i tidlegare urørt natur. Ulike revegeteringstiltak blir brukt for å redusere dei negative konsekvensane av slik utbygging: I Lista vindkraftverk vart ... -
What’s rocking in Bognelv? : a case study in hydromorphological conditions before, during and after restoration of a channelized river by studying tracer rocks and aerial photos
Johansen, Maja Konstanse Bernhoff (Master thesis, 2020)From 1930-1990 the river Bognelv in Troms-Finnmark County was strongly affected by technical intervention related to flood security which led to interruption of bed material transfer, and dramatical declination of salmonid ...
