In this PhD study, I aim to deepen our understanding of the influence of major mycorrhizal types, namely arbuscular mycorrhizae (AM) and ectomycorrhizae (EM), on the global soil carbon cycle and their potential distribution changes under future environmental shifts.

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

When a star is born in our Galaxy, it is quite likely that it has formed within a massive cluster, which hosts numerous high-mass stars bathing their lower mass neighbours in UV radiation.

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.

This thesis focuses on two processes involved in fighting infections: metabolism and immune cell motility and navigation.

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…

The use of N fertilizers has increased worldwide in the past century. While this increased input of N has increased food productivity, it has also contributed to decreases in biodiversity, soil quality and environmental health, including increases in greenhouse gas emissions.

Ooit was de spoorlijn van Kimberley naar Kambove in zuidelijk Afrika een teken van welvaart en vooruitgang. Inmiddels kenmerken de uitgeputte mijnsteden zich door verval en vervuiling. Hoogleraar Jan-Bart Gewald ontvangt een NWO L-beurs om te onderzoeken wat de langetermijngevolgen voor de wereld zi…

Arco Timmermans, bijzonder Hoogleraar Public Affairs aan het Instituut Bestuurskunde van de Universiteit Leiden, werd door Radio EenVandaag uitgenodigd om samen met Mark van Baal van Follow This te spreken over de invloed die een miljardenbedrijf als Shell op de buitenwereld heeft.

GLOBOX is a spatially differentiated multimedia fate, exposure and effect model. It is used for the calculation of spatially differentiated LCA characterisation factors on a global scale.

‘We moeten op zoek naar producten die gewone wegwerpplastics kunnen vervangen, bijvoorbeeld van plantmateriaal. Binnen een jaar of 20 is het gemiddelde plasticgebruik van een huishouden met grote slagen verminderd.’ Volgens Thijs Bosker, Universitair Hoofddocent aan het Leiden University College, in…

Steden, Voedsel, Water, Biodiversiteit, Bronnen en Energie: dit zijn de belangrijkste onderzoeksthema’s voor het CML. Ons doel is altijd om wereldwijd voorop te lopen in ons vakgebied. En echte impact te hebben met onze onderzoeksprogramma’s.

Van waterzuiveringsinstallaties tot een lekkere warme douche, de CO2-uitstoot ten gevolge van het watergebruik in de VS staat gelijk aan dat van 50 miljoen auto’s die een jaar lang rondrijden. In The Washington Post raadpleegt journalist Tik Root verschillende experts om te leren over manieren om ons…

As a contribution to the changing legislation and evolving societal attitudes concerning environmental issues, this project aims to enhance and manipulate the plants’ own natural defense mechanisms against western flower thrips (WFT).

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

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.

The progressive loss and degeneration of dopaminergic neurons is a major pathological hallmark of Parkinson's disease (PD). The onset and progression of PD can be triggered by multiple risk factors, for instance, genetic mutation, environmental exposure, and aging.

The field of science communication is very broad. Below is a list of organisations where SCS students can fulfill internships or where alumni have found jobs.

In times of hardships or crisis, local people know how to deal with it using their resourcefulness. Although efforts are sometimes made by the government to help them, they are fully aware that community support is at least equally important.

During post-embryonic development into adults, animals face an environment that fluctuates constantly. For example, in nutrient availability, temperature, and osmolarity (e.g., salt concentration).

Large carnivore population is globally declining as a result of the fragmentation of habitat, large prey depletion and retaliatory killing by pastoralists.

Every organisms in the tree of life faces the same challenge: the length of its DNA exceeds the volume of the cell it needs to fit in. Several strategies have evolved to solve this problem, one of them being the expression of proteins that bind and organize the DNA.

Global Environmental Extensions Multi-Regional Input-Output (EE-MRIO) analysis is often used to analyze how changes in global and national demand for products lead to socioeconomic and environmental impacts at the national level.

In this thesis unconventional tools based on fluidic interfaces were developed to study the surface and interfacial chemistry of graphene, to characterize the intrinsic properties of graphene, to disentangle the effects of substrate and of the environmental factors, and to improve handling protocols…

The rapidly increasing commercial application of metallic nanoparticles within products will inevitably enhance the amount of NPs being released into soil.

The investigation into the bidirectional communication between the gut and its host is a rapidly growing area of research, attracting considerable attention for its potential to provide crucial insights into health and disease.

Material circularity and energy efficiency are highly relevant and intertwined issues for the transition towards a carbon-neutral and circular built environment. In the Netherlands, the building sector has been rendered a priority towards a circular and low-carbon society.

Dissolution processes – next to aggregation processes - play an important role for fate prediction and environmental risk assessment of metal-based nanoparticles (MNPs). It is challenging to predict the kinetics of the dissolution process of MNPs in complex systems such as we can find in in vivo and…
