Copepods dominate the mesozooplankton spring-summer community in a South Norwegian fjord
2021
Master's thesis in Coastal ecology (BIO501) In this study the seasonality of the mesozooplankton community in spring and summer of 2019 at Midtfjordsskjær (MFS), South Norway, was investigated. Zooplankton samples were collected using a fine mesh sized plankton net (60 μm) and zooplankton were identified by microscopy based on 5 ml subsamples. Total zooplankton abundance ranged from 754 –1620 ind. m-3and peak abundance was found in May. Holoplankton dominated spring and summer communities at MFS constituting between 85,6 –98,8% of total zooplankton.

Master's thesis in Coastal ecology (BIO501) A three-year study was performed annually from 2017 to 2019 in Færder- and Ytre Hvaler national parks located in outer Oslofjord. Data collection was conducted in shallow- and deep water habitats using catch-based methodologies in 2017 - 2019 (eel fyke net and trap) and visual methodology (stereo-video)in 2019. In the period of study, a total of 9733 individual fish were recorded among 37 species from 19 families. Shallow water fish assemblage (1 - 10 m) sampled by fyke net was dominated by a selection of wrasses (goldsinny wrasse and corkwing wrasse) and small, stationary species of non-commercial importance. Sampled by trap at deeper habitats (1…

Mapping the invasion: spatiotemporal distribution of the Pacific oyster in Scandinavia
2021
Master's thesis in Coastal ecology (BIO501) The Pacific oyster (Magallana/Crassostrea gigas) is an invasive species to Scandinavia, originating on the Pacific coasts of Asia. Introduction to Europe of these oysters was a result of farming initiatives, put in place following declines of the native oyster species (Ostrea edulis). The oysters were introduced to Denmark, Sweden, and Norway in farming trials during the 1970s, however Norwegian and Swedish populations have also been a consequence of larval drift. They are not currently commercially farmed in any of the three countries due to the effects that wild populations have on the areas they invade. To map historical and present distributio…
