This thesis presents a study of vegetation and plant population dynamics in a local vegetation–environment context, and examines the importance of management regimes for the maintenance of grassland species. In the modern, ...

The principal aim of this study was to investigate vegetation-environment relationships and examine patterns of changes in forest understorey vegetation in five Chinese subtropical forests. Furthermore, an Ecological Field ...

The mapping of genealogical relationships between individuals, populations, subspecies and species is important for studies of evolutionary processes and biodiversity, and for conservation decisions. In this thesis, I have ...

This thesis addresses the spatial distribution and dynamics of vascular plant species in modern agricultural landscapes in SE Norway. This is done by analysing several data sets for species composition and environmental ...

Reconstructing molecular phylogenies and unraveling biogeographic histories of arctic plants are needed to obtain better insights into the processes of evolution, dispersal and colonization in this young biome. Studies ...

The Gardnos structure in Hallingdal, Norway is an eroded impact crater, presently consisting of impactites and crater infill sediments exposed within a roughly circular area of about five km diameter. Investigations in ...

Var grekernes mynter datidens flagg? Dette og andre historiske spørsmål drøftes i en doktoravhandling fra Universitetet i Oslo, hvor myntvesen og samfunnsliv på den greske øya Kos står i sentrum. I studien blir den materielle ...

The easier access to increasingly powerful computational approaches and tools in the field of distribution modelling, has contributed to a proliferation of data, applications, practitioners, guidelines, and novel theoretical ...

Despite the similar function of all sperm cells – to fertilise the egg – there is extraordinary diversity in sperm shape and length across taxa. This thesis aims to improve our understanding of how this diversity has ...
