(Master thesis / Masteroppgave, 2013)The epiphytic bryophyte composition between and within 73 ash trees (minimum stem diameter at breast height 20 cm) at Tungesvik, Etne, West Norway was investigated. The main aim of the study was to investigate patterns of ...
-
(Master thesis / Masteroppgave, 2013)The main objective of the present study is to describe and compare the morphology of the female genitalia within a selected number of species and families of the lower Diptera. The results are presented as two papers with ...
-
(Master thesis / Masteroppgave, 2013)Speciation involves the evolution of reproductive barriers that maintain the genetic integrity of species. Premating barriers, in particular, have been referred to as one of the most important mechanisms in keeping species ...
-
(Master thesis / Masteroppgave, 2013)Sorghum is ranked the fifth most produced food crop in the world, and is a dietary staple for over 500 million people in over 30 countries. It is the second most produced food crop in Africa, where cultivation of local ...
-
(Master thesis / Masteroppgave, 2013)The dry rot fungus Serpula lacrymans is known as one of the most aggressive fungal house invaders in temperate regions. Recent genetic and phylogeographic studies have shed light on the distribution, colonisation and ...
-
Allopatric speciation and multi-trait variation in the common chaffinch (Fringilla coelebs) complex (Master thesis / Masteroppgave, 2013)The common chaffinch (Fringilla coelebs) is a widespread passerine species in the West Palearctic, and is a common breeder in most of Europe, western Asia, northern Africa, and the Macaronesian islands in the Atlantic ...

Multigenerational effects of diet and temperature on size and fitness associated traits in Daphnia (Master thesis / Masteroppgave, 2013)This thesis presents a synthesis of experimental studies with Daphnia, in a multigenerational perspective. The main goal of the thesis was to investigate the role of diet (phosphorous (P) limitation) and temperature (10 ...
-
(Master thesis / Masteroppgave, 2013)The ridge-snowbed gradient is of high importance in alpine areas in structuring the vegetation cover. However, to what degree belowground fungal communities are affected by the gradient is much poorer understood. In this ...
-
(Master thesis / Masteroppgave, 2013)Host specificity among ectomycorrhizal (ECM) fungi seems to vary among different habitats, and it is difficult to draw general conclusions across environments. Little is known about the host specificity among arctic ECM ...

Description of a new Upper Jurassic ophthalmosaurid ichthyosaur from the Slottsmøya Member, Agardhfjellet Formation of central SpitsbergenRestricted Access (Master thesis / Masteroppgave, 2013)Ichthyosaurs were a group of marine reptiles that thrived in the Mesozoic seas. They evolved to be highly specialized marine predators, and were the first reptilian group to be entirely aquatic. This project’s goal was to ...

(Master thesis / Masteroppgave, 2014)As molecular and bioinformatics techniques are used more frequently and new marine habitats are analysed, a constant increase of marine fungal diversity has been reported, suggesting that marine fungi are a diverse but ...
-
(Master thesis / Masteroppgave, 2014)The present study elucidates the phylogenetic relationship within the tribe Riedelieae in family Zin-giberaceae, with a main focus on the genus Pleuranthodium and its intrageneric relationship. Previ-ous phylogenetic studies ...
-
(Master thesis / Masteroppgave, 2014)The three-spine stickleback is an adaptable fish with variation in morphology and behaviour, inhabiting saltwater, brackish water and fresh water. It is armoured with 30-35 bone plates along its lateral line. In addition, ...
-
Population Dynamics, Size Hierarchies and Neighbour Interactions of Early Colonizing Vascular Plants of a Norwegian Glacier ForelandRestricted Access (Master thesis / Masteroppgave, 2014)The population dynamics of the three early colonizing vascular plant species Oxyria digyna, Poa alpina and Ranunculus glacialis was studied in a chronosequence in the glacier foreland of Hellstugubreen in Jotunheimen ...
-
(Master thesis / Masteroppgave, 2014)Reproductive barriers between diverging taxa are necessary for speciation to occur. Premating barriers are thought to be of especially great importance, such as plumage colour which is often used in species recognition and ...
-
(Master thesis / Masteroppgave, 2014)Extractive foraging of underground storage organs (USOs) is believed to have played an important role in human evolution. This behavior is also present in wild chimpanzees (Pan troglodytes), who sometimes use tools in the ...
-
(Master thesis / Masteroppgave, 2014)The taxonomy of the staphylinid genus Mocyta was explored using molecular markers, in addition to a thorough investigation of the published literature regarding this genus and its proposed morphospecies. The aim was to ...
