Plants and their pollinators form complex interaction networks. Within these networks, species differ widely in the number of species they interact with.

Review of new technical decisionsupport systems in the environmental field, and application in water management decission processes.

Acidobacteria is a widely distributed phylum but their functional roles in ecosystem processes are still largely elusive.

The parabolic Anderson model (PAM), which is the Cauchy problem for the heat equation with random potential. The PAM is a mathematical model that describes how mass (i.e. matter or energy) flows in a medium in the presence of a field of sources and sinks.

Mathematician Oliver Nagy still vividly remembers the first time he learned about a random walk. ‘The lecturer told us to imagine a company of drunken students who wander in the streets. At each intersection, they would spin one of them around and all would go in the direction where he or she came to…

How do we approach education that facilitates creative confidence for students that leads to innovative solutions to society’s present day and future sustainability challenges? This education research project tackles a sustainability dilemma faced by households in everyday life viz.

1. What is the exact role of PIN proteins in PAT? 2. How is PIN polarity established, and how is it modulated by AGC kinase-mediated phosphorylation? 3. What is the role of the AGC kinase, as modulators of PAT, in translating environmental signals, such as gravity, light or mechanical stress, to plant…

This thesis explores Breaking of Ensemble Equivalence (BEE) in random graph models by examining the spectral properties of adjacency matrices. The goal is to identify spectral characteristics that differentiate random graph ensembles, enhancing the understanding of complex network structures and beh…

LCA has become an important method to study environmental impacts of human activities. Still, there are several methodological issues in LCA that can adversely affect the results reliability.

Fungal food spoilage often starts with a contamination with spores. Experimental data strongly indicate the existence of subpopulations of spores with different levels of resistance to preservation methods.

What is the role of the rebound effect in achieving environmental savings from transport eco-innovation? Are traditional definitions of the rebound effect adequate in the context of transformative innovations and multidimensional environmental issues?

Fate and toxicity of copper nanoparticles was related to the water chemistry of the environment and pristine size.

How to make a quantitative assessment of the relative contribution to toxicity of ions and particles? Is the toxicity of nanoparticles related to their size or shape? Which physicochemical property of nanoparticles is an appropriate dose metric of nanoparticles?

Using the principles of Industrial Ecology in Environmental Policy making in two cases: transition to a hydrogen economy and chlorinated compounds.

The Western Mediterranean is a key region to understand human dispersal events within and out of the African continent as well as for the eventual replacement of Neanderthals by anatomically modern humans during the Pleistocene. Central to any conclusive interpretation of archaeological and palaeoclimatic…

Nucleoid associated proteins maintain the architecture of the bacterial chromosome and regulate gene expression, hinting that their role as transcription factors may involve local three-dimensional chromosome re-modelling.

The world abounds with different footprints that calculate human impact on the environment. Environmental specialist Kai Fang is the first person to have developed a family of footprints that allow better measurement of environmental damage and the depletion of natural sources. PhD defence on 24 Nov…

We study the link between the acoustic, behavioral and physiological health of birds and prominent pollution factors. We aim to explore causation through experimental studies on detrimental factors like traffic noise, particulate matter and chemical toxins. Our primary target is scientific progress…
