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.

In this article, Meier & Nadler suggest that while non-citizen enfranchisement boosts participation across all citizens, citizens with immigration backgrounds are more reactive to the NCV rights in terms of higher turnout. In this way, the paper adds a critical nuance to individual-based explanations…

Far from the walls and fences that dominate the news, he reveals borders to be thick, multi-faceted and binational institutions that have evolved greatly in…

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…

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.

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

This part of the research programme is carried out by Prof. Dr. René Cappers. It focusses on the continuities and changes in the use of plants at Late Neolithic Tell Sabi Abyad, as well as on their implications as proxy evidence for the climate change c. 6200 BC. Parallel to the design of the other…

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.

Plant diversity is essential for us and our planet as it sustains the stability of our ecosystems, provides vital materials and food to us and supports many ecosystem services.

In this project, we will study the genetic and environmental drivers of woodiness and stem lignification at the level of plant‐to‐gene‐to‐molecule.

The 18th edition of SIP will be organised by Caroline Mueller at the University of Bielefeld, Germany. More information can be found on the SIP 2024 Homepage. The 17th Symposium on Insect-Plant relationships in Leiden has been held online from 25 to the 30 July 2021.

What are trait-trait relationships in wetlands? To what extent the so-called leaf economics traits deviate from terrestrial ecosystems? How traits specific to wetland plant relate to plant strategies? What’s the relationship between wetland plant traits to the ecosystem functioning (e.g. productivity,…

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 light of climate change, it is crucial to determine whether plant species can adapt to future climates to avoid extinction. Plants adapt to various conditions by altering their functional traits, such as leaf size or photosynthetic rate. Some traits appear linked and vary together between species,…

The leading textbook on governance and politics in the Netherlands. The authors offer a clear and comprehensive account and have revised the text to provide full coverage of recent important developments.

How many written parliamentary questions does each party put to each minister? Political scientists Simon Otjes (University of Groningen) and Tom Louwerse (Leiden University) studied the practice in Dutch parliament and found that parties use parliamentary questions strategically as part of their ‘permanent…

The soil ecosystem consists of the largest reservoir of biodiversity on Earth.

Education in (Chinese) Medicinal Plants associated to the Hortus botanicus in Leiden - Which Traditional Chinese Medicinal plants can be grown in the Hortus? - Establishing of a database which Chinese medical plants are available in Dutch Botanical Gardens - Data validation (correct identification,…

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

Both play and politics have the potential to create worlds in which new rules apply, meanings are created, and possibilities emerge for collaboration, strategy and creative solutions. In this sense, play and politics have always been very much alike. But what happens to this kinship in a post-digital…

The availability of complete plant genome sequences together with the ever increasing amount of data on the molecular, cellular and physiological mechanisms of plant development require mathematical and computational models to obtain a complete overview of and generate new insights into the quantitative…

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…

1. What is the exact role of PIN proteins in PAT? 2. How is PIN polarity established, and how is it modulated by AGC kinase-mediated phosphorylation? 3. What is the role of the AGC kinase, as modulators of PAT, in translating environmental signals, such as gravity, light or mechanical stress, to plant…

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