A report written by Anette Aune, Kristian R. Fjeld, Joseph C. Lawrence and Adam Mortensen Maurolicus muelleri is a dominating mesopelagic fish in Norwegian fjords, yet little is known about its photophores in relation...
A report written by Nora Solheim Drosophila melanogaster (the fruit fly) is a very well-suited model organism within the genetic fields of biology. It has a short generation time and a simpler genome than...
A report written by Ingrid Vaksvik This study explores the interactions between domestic herbivores and beetles in the fjord system of the Nordhordland Biosphere Reserve. Fields grazed by sheep had overall higher beetle abundance,...
Hoverflies (Syrphidae) are a family of flies of the Diptera order that provide a range of ecological services to agriculture. This report gives an overview of what hoverflies are, their importance to agriculture, and subsequently what services they provide to aid pollination and ecosystems. A description of species diversity, abundance, and phenology in inner Hardanger is provided.
Det er funnet at Norge lagrer store mengder karbon, men det er gjort lite kartlegging av Soil organic carbon (SOC) og karbon i biomasse over bakken på lokalt nivå (Bartlett et al., 2020). Denne studiens formål er å kartlegge SOC og karbon i biomassen over bakken i naturtyper i Bergen og omegn. Vi tar for oss tre naturtyper i fastlands-Norge. Disse er skog hvor gran, furu, eik og andre løvtrær dominerer, åpent lavland slik som gressmark, jordbruksareal og lynghei, og våtmark som myr og torvmark.
Human activities keep exploiting lands to the detriment of biodiversity and species that are declining, owing to this habitat loss. Hence, understanding what use a species makes of its habitat contributes to preserving the species by establishing conservation strategies. We studied the habitat uses and winter behaviour of a coastal population of black grouse (Lyrurus tetrix) during winter 2021-2022 in the heathlands of Lygra, a coastal island in western Norway.
Our aim for this report was to investigate if we can use herring scales to distinguish between autumn and spring spawning herring. Our hypothesis was that herring that is genetically fit for autumn spawning (genetic autumn spawners) have a relatively wider first scale increment size than genetic spring spawners, due to longer first growth season. We further hypothesize that this difference could be used to differentiate between the two spawning groups.
Heavy metal pollution poses a severe threat to aquatic environments, especially in urban coastal areas of high value. This study investigated the elemental composition of particulate matter and the possible impact of heavy metals on phytoplankton biomass in Puddefjorden(PUD) and Store Lungegårdsvannet(SLV), Bergen during spring 2021.
