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…

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…

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.

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.

Het masterprogramma van Arts and Culture aan de Universiteit Leiden heeft een unieke positie op de kruising tussen kunstgeschiedenis en museologie. Door middel van toonaangevend interdisciplinair onderzoek geeft deze opleiding een sterke academische basis voor een verscheidenheid aan carrières in musea,…

Vinasse is a major by-product generated by the sugarcane biofuel industry. It is a source of microbes, nutrients and organic matter and often it is recycled as fertilizer.

Striga hermonthica, commonly known as witchweed, infests major cereal crops in Sub-Saharan Africa causing severe yield losses and threatening the livelihood of millions of resource poor farmers.

What are the global relationships between environmental conditions and abundance of distinct types of mycorrhizal fungi in soil and plant roots?

‘Wat ik aantrekkelijk vind aan het bodemleven, is dat het stuurbaar is,’ verklapt onderzoeker Martijn Bezemer van het Instituut Biologie Leiden (IBL). ‘Dat je kan zeggen: wat wil je? En dat ik de bodem dan kan omtoveren tot iets wat jij nodig hebt. Ten minste, dat dachten we.’

Jan Willem Erisman wilde als kind al dingen beter maken. Als hoogleraar Duurzaamheid en Milieu is hij daarom ook buiten de universiteit actief. Hij staat bekend als de stikstofprofessor: in de media, maar ookin de Tweede Kamer legt hij het stikstofprobleem uit. Recent trad hij toe tot de Europese Soil…

The Department of History and Art History externe link at Utrecht University is looking for a candidate for the PhD-project “The (R)evolution of Reconstruction: an analysis of digital facsimiles”. This project analyses the value of digital facsimiles for researchers, heritage institutions, and museum…

The Dutch Research School Art History (OSK) and Utrecht University organize the Technical Art History Days. On April 4 and 5, experts present and discuss current research at Utrecht University that brings together material and digital approaches for the study of art and heritage.

De conferentie brengt wetenschappers, beleidsmakers en andere professionals in het migratiedomein bijeen rond belangrijke migratievraagstukken.…

1. To what extent do metallic NPs added to soil extractions change the activity, abundance, or community composition of microbes? 2. How do the effects of metallic NPs on soil microbes differ from the effects of the ions shedding from corresponding NPs?

How the global distribution of vegetation stands dominated by arbuscular and ectomycorrhizal plants relate to principle aspects of belowground carbon accumulation processes?

A team of researchers has dated a prehistoric painting in Indonesia to at least 51.200 years ago, they have proposed in a study that this painting is the oldest known example of “figurative” art.

Microbiome composition of the spermosphere and the rhizosphere of wild and modern bean accessions grown in an agricultural and a native soil from Colombia was characterized by metagenomics and cultivation-dependent approaches.
