In this thesis, the role of plant-mediated soil legacy effects in shaping aboveground plant-insect interactions was investigated.

This ecological community has long been known to affect host biology, and their diverse roles have been further clarified in recent years following numerous studies of animal:microbiota interactions in diverse systems.

What is the effect of light at night on plant phenology and physiology, and how does this affect plant interactions with other species?

This thesis deals with the use of sound in interactions in the context of participatory systems and data sonification. We investigate an interactive environment where participants perceive information of the data through sound elements.

Mycoheterotrophy is a particular mode of life in which plants obtain carbohydrates from their associated fungal partners, instead of by using photosynthesis.

The lipid membrane is a basic structural component of all living cells. Embedded in this nanometer-thin barrier, membrane proteins shape the membrane and at the same time respond to the shape of the membrane.

Biological cells, the basic building blocks of all life forms, are surrounded by a lipid membrane. More than half of the membrane is occupied by membrane proteins, which can regulate the cell functionality through specific arrangements.

The aim of this thesis is to study cell-cell interactions and the development of an assay to explore and quantify the exchange of membrane compounds.

Streptomyces are bacteria abundant in soil that participate in diverse and complex interactions. These bacteria are the main producers of the antibiotics we currently use in the clinic.

Breeding for resistance becomes more and more important because we want to reduce the use of pesticides. A fast and cheap alternative can be to make use of morphological or chemical markers.

In this thesis, the researcher developed a nanosystem based on the metallophilic Interaction between cyclometalated complexes.

Cardiovascular disease is the leading cause of death worldwide.

The studies presented in the work show the potential of the integrative use of biophysical data in defining the structural basis of protein interactions.

The mycorrhizal symbiosis is among the most widespread species interactions on Earth⁠. This thesis focuses on orchid mycorrhiza, a unique mycorrhizal type that has caught scientists’ attention for centuries⁠.

Low-mass main-sequence stars like our Sun are continuous sources of outflowing hot magnetised plasma. In the case of the Sun, this is known as the solar wind, whereas for other stars they are called stellar winds.

The thesis describes the use of electron paramagnetic resonance (EPR) spectroscopy, in continuous wave and pulse modes, to address the interaction of α-Synuclein (αS) with membranes and the aggregation of αS.

Large carnivores and humans, along with their livestock, have co-existed for thousands of years. However, human population growth and an increase in economic activities are modifying the landscape for large carnivores and their prey.

Modeling and analysis of cyber-physical systems are still challenging. One reason is that cyber-physical systems involve many different parts (cyber or physical), of different nature (discrete or continuous), and in constant interaction via sensing and actuating.

This thesis focus on the interaction between M dwarf stellar winds and Galactic cosmic rays and the possible effects on the habitability of exoplanets.

Op 21 februari 2019 verdedigde Ruben Zandvliet zijn proefschrift 'Trade, Investment and Labour: Interactions in International Law'. Het promotieonderzoek is begeleid door promotor prof. dr. N.J. Schrijver.

Nederland verliest plantensoorten die afhankelijk zijn van bestuiving door insecten. Milieuwetenschapper Kaixuan Pan toont dat aan na analyse van 87 jaar aan metingen van meer dan 365.000 locaties. Het nieuws is verontrustend voor onze biodiversiteit en de voedselzekerheid. ‘75% procent van onze gewassen…

The soil ecosystem consists of the largest reservoir of biodiversity on Earth.

Novel entities may pose risks to humans and the environment. The small particle size and relatively large surface area of micro- and nanoparticles (MNPs) make them capable of adsorbing other novel entities, leading to the formation of aggregated contamination.

Wat is 'Interaction between Legal Systems' (ILS) en wat betekent het als profileringsgebied binnen de Faculteit der Rechtsgeleerdheid? Hier meer over op de startbijeenkomst van ILS 2.0 op 26 oktober 15.00 – 17.00 in de Grotiuszaal (A051 KOG). De middag wordt afgesloten met een borrel in de Global Lo…

The outbreaks of AIDS and COVID-19 showed clearly how infectious viruses can influence people’s lives. Investigating the changes in the host metabolism may provide a paradigm shift to consider immune-metabolic interactions as therapeutic targets.

During embryonic growth, cells proliferate, differentiate, and collectively migrate to form different tissues at the right position and time in the body.

Can we distinguish the effects of pesticides from other abiotic and biotic factors that occur in the field? And how do these factors interact with pesticides?

In deze dissertatie onderzoekt Galikyan hoe de multidimensionaliteit van gegevens over interactie tussen studenten en de veelzijdigheid van deze interactie van invloed zijn op de meting van interactie tussen studenten in digitale leeromgevingen.

Curved single crystals provide variable, but well-defined surface structures.

The external tissues of plants and animals are colonized by microbial communities termed microbiota. When organisms are exposed to environmental pollutants, these substances will therefore encounter microbiota at the exposure interface.
