Op 1 oktober 2019 verdedigde Emile Cammeraat zijn proefschrift 'Economic Effects of Social Protection'. Het promotieonderzoek is begeleid door promotoren prof.dr. K.P. Goudswaard en prof.dr. P.W.C. Koning.

Ice, the solid state of water, plays an important role on our planet as well as the entire universe.Despite the fact that an individual water molecule has a very simple structure, its chemical bonding in the solid phase can be surprisingly complex.

What are interactive effects of human pressures on aquatic communities?

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

In dit onderzoek wordt hersenontwikkeling voor het eerst direct gelinkt aan sekseverschillen en schoolprestatie. De resultaten ontkrachten de mythe dat jongens achterlopen in hersenontwikkeling.

The thesis describes terrestrial field trials aimed to detect side-effects of pesticides within the framework of pesticide registration procedures. Field trials were developed using vascular plants Brassica napus and Poa annua, caterpillars Pieris brassicae and effects on decomposition were studied…

We find ourselves in an era of transition, not just towards a more computing- and data-driven society but also away from unsustainable fossil fuels as an energy source.

We have studied the impact of particle shape anisotropy, multivalent interactions and flexibility on systems of micron-sized colloidal particles.

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.

A management strategy has been developed for field margins to reduce pesticide drift to non-target areas and to promote biodiversity on arable land. To this end, 3 and 6 m wide strips along the edges of winter wheat, sugar beet and potato crops have been left unsprayed with herbicides and insecticides…

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 describes the role of pollution, specifically neonicotinoid insecticides, as an actor of the ongoing biodiversity decline.

How are links between macro-invertebrate diversity and ecosystem functioning influenced by anthropogenic pressures?

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?

Anthropogenic noise negatively affects wildlife in a wide range of taxonomic groups.

Anthropogenic noise has been shown to affect marine animals in various ways, this may have fitness consequences at individual and population level. This thesis aims to increase insight into the quantification of sound-induced behavioural responses that are relevant to fitness, and into factors that…

This thesis combines field and laboratory studies to address some of the most pressing questions in the field of microplastic research.

The effects of anthropogenic noise on interactions between predators and their prey are still little understood.

Hoe kan de methode om de gecombineerde effecten van metaal-gebaseerde chemische stoffetn te bepalen worden verbeterd?

This thesis has shed light on some of the ways in which the local electrolyte composition can differ from the bulk and how these changes in the local reaction environment can determine the activity and/or selectivity of two important electrocatalytic reactions, namely, electrochemical CO2 reduction…
