In hoeverre verandert het gebruik van 360-immersie bij een spreektaak de uitgelokte spraak, vergeleken met 2D-presentaties?

How were the Russians, under early modern conditions, able to incorporate this distant, undeveloped and, because frequent nomadic attacks, dangerous territory? And what role did the Kolyvan-Voskresensk plants play in this process?

Trigonostemon Blume is a plant genus in the family Euphorbiaceae comprising 59 species.

Promotor: P.J.J. Hooykaas, Co-Promotor: E.J. van der Zaal

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…

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

Sorghum (Sorghum bicolor) is a major cereal crop that millions of subsistence farmers in Sub-Saharan Africa (SSA) rely on. However, the scourging impact of the root parasitic weed Striga (Striga hermonthica, a.k.a. “witch-weed”) has remained a major constraint hampering the productivity of sorghum in…

Solar energy harnessed by plants and algae has great potential to be converted into biofuels for future generations.

Promotor: Prof.dr. P.G.L. Klinkhamer, Co-Promotor: T.J. de Jong

Plants, are sessile organisms, have developed strategies to adapt to changes in their environment, in part by altering their growth and development.

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

The name ‘Jambi flora’ refers to fossil plants found as part of a rock formation from the Early Permian (296 million years old), located in the Jambi Province of Sumatra, Indonesia.

This thesis describes the functional analysis of the Arabidopsis AHL15 gene.

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

Freshwater is an important resource, but at a great risk of species decline due to habitat loss, pollution and over-exploitation, and invasive alien species.

Natural vanilla flavor is one of the most important in the world. However, the cost of this flavor is expensive. Production of this flavor by alternative methods, could reduce the cost.

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…

Aspergillus niger is an important industrial producer of organic acids and enzymes producing large amounts of spent fungal biomass.

Supervisor: P.J.J. Hooykaas

This thesis explores how bees and hoverflies are distributed across the Dutch landscape and how ecological and landscape factors shape their occurrence.

Er komen steeds meer plastics in onze leefomgeving, maar over de gevolgen daarvan is weinig bekend. Christian Tudorache van het Instituut Biologie Leiden en Martina Vijver van het Centrum voor Milieuwetenschappen Leiden spraken bij BNR Nieuwsradio over de resultaten van onlangs gepubliceerd onderzoek…

Climate change is a challenge for both current and future generations. New biological resources have to be developed in order to meet the demand for energy as well as the demand for food.

Plant architecture has distinct forms in different plant species, but also within a species the finalarchitecture of a plant is determined by its gradual development and changes therein induced by environmental conditions during the plant’s life cycle.

Promotores: G.A. Persoon, H.H. de Iongh

This thesis presents the systematics, epidermal defense, and bioprospecting of wild orchids.

In the Schouwburgstraat, LUGO is currently redesigning the back-garden in order to increase biodiversity and make it a more beautiful space. Throughout October 2023 until March 2024, we will be making changes to the garden with our team of volunteers.

Artificial photosynthesis has recognised potential to produce green and sustainable fuels from earth-abundant resources such as water, carbon dioxide (CO2), and sunlight.

In recent decades, climate change has led to more frequent and severe drought events, causing serious consequences such as increased forest mortality and significant crop yield losses. Understanding how drought affects plants, especially economically important herbaceous species, is crucial for predicting…

This thesis presents the results of a study on the interfaces of insulating oxides with and without the insertion of a magnetic layer.

In this thesis, we study systems of electrons in which strong correlations give rise to emergent exotic physics.

Spectroscopic studies on fluorescent single molecules in organic condensed matter does not only provide information about the molecule itself, but also its near environment. By suppression of phonon-induced broadening of spectral lines through cooling to low temperatures, small changes in the spectral…

Heeft het gebruik van medicijnen en drugs invloed op mijn persoonlijkheid? Wat zijn de (langere-termijn) gevolgen van de leerpil 'Ritalin'? Kunnen (party)drugs en medicijnen met rijden in het verkeer samengaan? Wat doen verslavende stoffen met mijn brein?

De psychologen Fenna Poletiek en Erik de Kwaadsteniet krijgen van vakbond FNV een subsidie om te onderzoeken hoe mensen zich gaan gedragen ten opzichte van werk als ze een basisinkomen krijgen. Hoe gaan ze op zoek naar een antwoord?

To conclude, this thesis provides valuable methodological insights to address data gaps and improve environmental impact assessments within the circular economy, with a particular focus on product reuse and sharing practices. Through empirical analysis and innovative approaches, it aims to support informed…
