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…

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.

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.

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…

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 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.

Early cave paintings of hunting scenes may give the impression our Stone Age ancestors lived mainly on chunks of meat, but plants were just as key to their survival. Plants rich in starch helped early humans to thrive even at the height of the last Ice Age, Leiden archaeologist Amanda Henry tells Horizon…

This comparative study investigates court politics in four kingdoms that succeeded the south Indian Vijayanagara empire during the sixteenth to eighteenth centuries: Ikkeri, Tanjavur, Madurai, and Ramnad. Building on a unique combination of unexplored Indian texts and Dutch archival records, this research…

A comparative analysis of legitimation strategies in tree hybrid regimes: Russia, Venezuela, and Seychelles.

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

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

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…

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

Beyond the immediately visible plenum, parliaments are highly complex institutions. They work through various venues in which decisions are prepared or even taken. The two main institutions in this regard are parliamentary party groups, which comprise legislators who are elected under the same party…

Breeding for resistance becomes more and more important because we want to reduce the use of pesticides. A fast and cheap alternative can be to make use of morphological or chemical markers.

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…

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…

This thesis describes how different colours of light affect various aspects of the growth and development of Arabidopsis and tomato plants⁠.

Plastics have become an integral part of modern society due to their versatility and durability.

Why did India develop a strong military partnership with the state of Irael, after having ignored it for 42 years? How could both countries develop defense ties in spite of limited political leadership involvement? Finally, what are the prospects for defense relations as India grows to become one of…

The project investigates the implementation of policies and practices related to reconciliation and the strengthening of government capacity in the Odesa and Kharkiv regions of Ukraine.

It is often said that the links between political parties in Africa and their voters are clientelist, rather than programmatic. The familiar image is that of African ‘big men’, displaying personal wealth while being respected and celebrated in the community for sharing their riches. Yet, political scientist…

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 research group Politics, Culture and National Identities 1789-present investigates a wide range of national political cultures in Europe and the Americas in the 19th and 20th centuries. Instead of only analyzing high politics (the acts of governments and political parties), the research group focuses…

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

The studies described in this thesis deal with glycosidases, in particular alpha-galactosidases.

An experimental comparison of the impact of liberal norms on a population residing and socialised within a democracy (the Netherlands) with a population in an autocracy (China) and their respective supports for war with another state shows that the level of liberal norms in the democratic experimental…
