In vivo proton magnetic resonance spectroscopy (1H-MRS) data often exhibit baselines or low-amplitude signal variations resulting from residual water, imperfectly suppressed lipids, low-amplitude metabolites not considered for fitting, and other features not represented in a basis set. While multitudinous approaches exist to model these baselines in 1H-MR spectral analysis, many continue to lack s

Declining butterfly abundance over recent decades coincides with both habitat loss and increasingly warmer springs. Warmer temperatures could pose a problem for ‘capital’ breeders, especially those species that enter winter diapause as a pupa or adult, since a higher metabolic rate pre-eclosion is expected to further deplete lipid stores needed for egg production. We undertook an experiment on Pie

Changes in plant diversity and abundance due to land-use modifications can induce plant-pollinator trophic cascades, potentially leading to long-term shifts in pollination services. Our ability to mediate such loss of pollination services through informed landscape management is limited by insufficient understanding of long-term adaptations of wild pollinators to land-use, especially when accounti

This brief summarizes expert knowledge on what really works to protect pollinators. To guide and assist national governments and other relevant governmental bodies in the endeavor to stop and reverse pollinator decline, this brief is intended for everyone interested in pollinator and nature restoration, from local practitioners to national and international governmental agencies.

The 1990s were significant for several events promoting environmental protection and the sustainable use of natural resources. For instance, both the United Nations Conference on Environment and Development in 1992, which stressed the need to stop the overconsumption of natural resources and the United Nations Framework Convention on Climate Change endorsed a framework to combat climate change. Si

Biodiversity in human-dominated landscapes is declining, but evidence-based conservation targets to guide international policies for such landscapes are lacking. We present a framework for informing habitat conservation policies based on the enhancement of habitat quantity and quality and define thresholds of habitat quantity at which it becomes effective to also prioritize habitat quality. We app

Context: Organic farming aims to make agriculture more sustainable, but its sustainability benefits may be offset by lower yields compared to conventional farming. Avenues to increase organic yields have been studied extensively, but there is a lack of research using integrated approaches that consider co-variation between different organic management practices within commercial farming systems. M

Background: Increasing carbon stock in standing forests is one of the proposed ways to mitigate climate change. However, in production forests, this typically would lead to reduced harvesting possibilities and thus reduced financial gain for the forest owners. The size of this reduction should depend on the chosen target level of the carbon stock as well as the required speed of accumulation. Furt

Production of agricultural biofuels is expected to rise due to increasing climate change mitigation ambitions. Policy interventions promoting targeted bioenergy solutions can be motivated by the large environmental externalities present in agricultural systems and the local context of biomass production co-benefits. Introducing energy crops in crop rotations in arable land with depleted Soil Organ

In times of major global interconnectedness and environmental change, the pressure to identify, create, and exploit new resources is certain to intensify. Given that there are unavoidable trade-offs, conflicts, and arenas for violence involved when increasingly more material and immaterial things are turned into resources, we call for explicit research on the very process – a process that we label

The EU's Common Agricultural Policy (CAP) has had limited success in mitigating agriculture's environmental degradation. In this paper we simulate the impacts of the 2013 “greening” reform on biodiversity and ecosystem services in environmentally contrasting landscapes. We do this by integrating an agent-based model of structural change with spatial ecological production functions, and show that t

Intensification of arable crop production degrades soil health and production potential through loss of soil organic carbon. This, potentially, reduces agriculture's resilience to climate change and thus food security. Furthermore, the expected increase in frequency of adverse and extreme weather events due to climate change are likely to affect crop yields differently, depending on when in the gr

Context: The global demand for food is expected to continue increasing for decades, which may drive both agricultural expansion and intensification. The associated environmental impacts are potentially considerable but will depend on how the agricultural sector develops. Currently, there are contrasting regional developments in agriculture; expansion and/or intensification in some regions and aban

The aim of this thesis is to develop statistical models to reconstruct past land cover composition and human land use based on fossil pollen records over Europe for different time periods over the past 6000 years. Accurate maps of past land cover and human land use are needed when studying the interaction between climate and land surface, and the effects of human land use on past climate. Existing
