(University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2023)Individuals within a population often differ predictably in their behaviour compared to other members across time and/or context, often termed personality, which can have major implications for ecology and evolution. Personality includes variation ... -
(University of Iceland, School of Engineering and Natural Sciences, Faculty of Earth Sciences, 2023-06-15)Focussing upon the monastic sites of Þingeyraklaustur and Helgafellsklaustur, palynological data are utilised to explore the role of Icelandic monasticism with regard to vegetation change and land use in the Medieval period. Consideration is also given ...

(University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2022-12-19)With increasing renewable energy infrastructure (REI) developments and growing nature-based tourism (NBT), their encounters are becoming more likely. To facilitate sustainable development of both, it is important to gain more knowledge on the ...
-
(University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2022-11)In the wake of increasing awareness of global warming, peatland conservation and restoration receive impetus by efforts to sequester carbon. Peatlands comprise a significant component of the global carbon cycle as they store up to 30% of global ...
-
(University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2022-09)Surtsey is a volcanic island located on the south-east offshore extension of the Icelandic rift zone. It was formed during successive eruptions from the seafloor in 1963-1967 and has been officially protected and studied ever since. It represents ...
-
(University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2022-06)Biodiversity is declining globally, primarily driven by anthropogenic changes and alterations of natural habitats. In lowland Iceland, human impact has increased considerably in the past decades, often involving an increase in numbers of anthropogenic ...
-
(University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2022-06)The theory of divergence by trophic polymorphism, an important part of diversification in vertebrates, has recently been extended to encompass the interplay of developmental, ecological and evolutionary processes (Eco-Evo-Devo dynamics). However, ...
-
(University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2021-06)Frequent tephra deposition and a steady influx of aeolian material of diverse origin dominate soil formation in Iceland. Little is known about the weathering behaviour, mineral formation and alteration of tephra and Icelandic soils after tephra deposition. ...
-
(University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2021)Genomic population bottlenecks and small population sizes are well described and well-studied areas of biology. However, few studies analyse samples from before and after a population have gone through a genetic bottleneck, and thus studies commonly ...
-
(University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2021-10)Climate warming in sub-Arctic regions leads to shifts in plant communities and retreating glaciers. Mosses and lichens contribute to important ecosystem processes in these environments, including nitrogen fixation via their microbiome. The first objective ...
-
(University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2021-09)As industries expand in sub-Arctic and Arctic waters there are increased conflicts between these industries and cetaceans. The aim of this work was to investigate the issue of cetacean bycatch/entanglement in Iceland, with a particular focus on the ...
-
(University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2021-06)Increasing water temperatures are predicted worldwide, with high amplitudes in the Arctic and sub-Arctic regions exceeding predictions for other regions. An understanding how Atlantic cod (<i>Gadus morhua<i>) reacted to changing environmental conditions ...
-
(University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2021-06)The thesis examines the dynamics of Arctic social-ecological systems (SES) that enable human wellbeing benefits through whale ecosystem services (ES). It does so through a review of relevant literature, construction of conceptual models, two primary ...
-
(University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2021-04-29)The management of marine resources pose a difficult commons problem as monitoring behavior is difficult and benefit flows from the resources are uncertain. Implementing individual transferable quota (ITQ) is a management regime in which quasi-property ...
-
(University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2021-01-28)The geo-political importance of the Arctic is growing while at the same time the onset of climate change has resulted in increasing environmental and social pressures both on Arctic states and the governance architecture through which Arctic issues ...
-
(University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2021-01)The marine ecosystem around Iceland is shaped by its position in one of the most hydrographically complicated regions of the North Atlantic. The response of marine populations to those diverse conditions is expected to be different across taxonomically ...
-
(University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2021-02)Innate immunity of the lung epithelium provides efficient defenses against pathogens or other stress factors by secretion of antimicrobial peptides, presence of cellular junction proteins and autophagy. Upon activation through epithelial cell receptors ...
-
(University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2020-12)Sustainable energy development is a cross-cutting policy objective with the ultimate aim of a sustainable energy future. However, what that future involves and how it can be reached is unclear. The aim of this PhD thesis is to address the question ...
-
(University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2020-12)The population dynamics of marine fish are driven by many top-down and bottom-up processes operating across multiple life-history stages. The majority of teleosts produce large quantities of offspring which experience high mortality rates early in ...
-
(University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2020-11)This PhD thesis explores what can be considered a sustainable energy system on a global scale and what methods and tools can help sustainable energy policy design and assessment. Energy system modelling and sustainable energy system narratives are the ...
