Intraspecific variation in egg size and its effects on offspring fitness is well documented in fishes. Yet whether or not differential per propagule maternal investment (egg size) can influence phenotypic diversification is little understood. Arctic ...

The development and expansion of agriculture throughout the world has been a major driver of biodiversity loss in recent decades. Icelandic agriculture is currently not as intense and widespread as in many other western countries, and the effects of ...

Designing a truly sustainable fisheries management regime has been a challenge internationally. Iceland is not an exception in this regard. Icelandic fisheries and their management has gone through tremendous changes since the 1980s. The implementation ...

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 ...

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 ...

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 ...

Variation in morphology of shelled marine gastropods across small spatial scales may reflect restricted population connectivity, resulting in evolutionary or plastic responses to environmental heterogeneity. Species delimitation of shelled gastropods ...

The cyclically-repeated song of the male humpback whale (Megaptera novaeangliae) is an important social display on their breeding grounds, functioning in male-male interactions and/or as a reproductive display to attract females. The songs are gradually ...

A holistic understanding of the underlying dynamics of sustainable energy system development and its effects on socio-economic and environmental aspects, in different national contexts, is necessary for improved decision making with regards to sustainable ...

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 ...
