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

In this thesis, I focused on studying the above- and belowground interactions of J. vulgaris from a plant-soil feedback (hereafter, PSF) perspective. I investigated the temporal variation of negative PSF and examined the effects of root-associated bacteria on plant performance and aboveground herbiv…

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

The overall objectives of my thesis are to investigate the dynamics of the sorghum root microbiome and to explore the beneficial effects of the root microbiome on sorghum growth and stress tolerance.

Plants and soils from natural ecosystems harbor great diversity of soil microorganisms, which could potentially contribute to the sustainability of horticulture. The knowledge about using wild plant species and soil from natural ecosystem to improve the crop health will advance the application of ecological…

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.

Description of Effects of glufosinate-ammonium on off crop vegetation.

De missie van het Plant Sciences onderzoeksprogramma is om bij te dragen aan de duurzame productie van gewassen van hoge kwaliteit, bloemen en hoogwaardige producten met een biologische basis. Dit wordt gerealiseerd door het opdoen van fundamentele kennis over biologische processen omtrent de ontwikkeling…

Plant exudates appeared long time ago in the history line of life in the early Devonian. They are typical saps produced by specialized cells.

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.

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

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

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…

This thesis explores interfacial conductance and electric field-effects in LaAlO3/SrTiO3 heterostructures.

Biodiversity enables ecosystems to thrive through the synergy of functional differences among organisms. While human well-being strongly depends on biodiversity-driven ecosystem services, human actions are also at the root of current unprecedented biodiversity declines.

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.

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.

By growing in a soil plants change the biotic and abiotic properties of the soil in which they grow.

Plants are colonized by an astounding number of microorganisms that can provide different life-support functions, including nutrient acquisition and protection against (a)biotic stresses like drought or pathogen attack.

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…

Plant-microbe interaction resulted in different physio/chemical responses by host plant and interacting rhizobacteria.

There is concern about the threat that nanoplastics (NPs) may pose to both wildlife and humans. This thesis explores the mechanisms of toxicity of polystyrene nanoparticles (PS-NPs) in chicken embryo.

Soil biodiversity is of great importance for the maintenance of multifunctionality in terrestrial ecosystems.

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

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?

Wetland plants are distinguished from plants of other terrestrial ecosystems by their adaptations to specific habitat stresses, including waterlogged and flooding and the subsequent abundance of phytotoxic compounds.

In dit artikel onderzochten Martin Sievert en Jonas Bruder of en hoe administratieve lasten van invloed zijn op de perceptie van burgers van het welzijnsbeleid en hun houding tegenover uitkeringsgerechtigden.

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…

The plant hormone auxin regulates plant growth and development through polar cell-to-cell transport-generated maxima and minima. PIN FORMED (PIN) auxin efflux carriers determine the direction of this auxin flow through their asymmetric placement on the plasma membrane (PM).
