Fostering multi-polar perspectives that engage more connected, nuanced and pluralistic understandings of the world. Global Interactions encourages and supports research that provides significant new insights on these global processes across time and space.

Plant Sciences' contribution to the Host-Microbe Interactions research theme is to dissect how microorganisms and microbiomes interact with the plant host and the insects on those plants, and how these insights may be harnessed to improve plant growth and health, by steering microbiome composition and…

We like to welcome you kindly to the Dutch Extract Library.

A management strategy has been developed for field margins to reduce pesticide drift to non-target areas and to promote biodiversity on arable land. To this end, 3 and 6 m wide strips along the edges of winter wheat, sugar beet and potato crops have been left unsprayed with herbicides and insecticides…

Kirsten Leiss, at the IBL since 2001, is developing new ways of crop protection in order to decrease the use of pesticides: As a model she uses the thrip, a tiny insect which causes economic losses worldwide by silver- and growth damage and virus transmission to vegetables, fruits and flowers.

What are key regulators of plant ageing that can reverse ageing in plants (rejuvenation), and how can we use this knowledge to improve crop plants?

Plants love favourable microbes such as bacteria and fungi: they grow better and become healthier. Jos Raaijmakers, Professor of Microbial Ecology, is in search of the right microbes to be used in agriculture. Inaugural lecture 13 November.

How do common marmosets combine their calls into sequences and how are their vocalisations influenced by reproductive state?

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.

Development & Disease is one of the four research themes of the Institute of Biology Leiden.

Soil is a home for an unbelievable diversity and abundance of microbial life that is essential for supporting life on our planet.

Exploring linkages between energy and material use and implications for sustainable development.

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

The role of domestic and wild resource exploitation in Bronze Age subsistence

What categories exist in the languages of pastoralists? Do these semantic concepts reflect universal or languagespecific tendencies? What (environment? culture?) governs the similarities (or the differences) attested crosslinguistically in cattle colour systems?

Charisma K. Lepcha (PI, Sikkim University), Pradyut Guha (co-PI, Sikkim University), Rajib Sutradhar (co-PI, Christ University Bangalore) and Erik de Maaker (Leiden University) have been awarded a two-year grant of USD 18.000 to conduct research on the impact of ‘green farming’ on the sensitive mountain…

A new 5.7 million euro research project will ensure that lettuce will be more resistant to pathogens and climate effects and will grow better in new cultivation systems. Together with other Dutch researchers, Leiden biologists will map the characteristics and genetic information of 500 wild and cultivated…

An environmental and palaeo-economic reconstruction.

This report investigates the different approaches in the authorization process of GMOs for commercial use in the European Union and the United States of America. Three main aspects are considered and analyzed as potential causes of differences in the authorization process of GMOs for commercial use.…

Global Interactions is pleased to announce that we have awarded a GI Advanced Seminar grant to Dr. Mariana Francozo (Archaeology) for 'Historia Naturalis Brasiliae' and a Breed Grant for 'Global Earth Matters' to Dr. Sabine Luning (CA-DS) and Dr. Wayne Modest (RCMC)

Do large deletions represent a risk during CRISP/CAS9-mediated genome editing in plants?

In this project, we use social network analysis to analyze the behavior of users in online forums and associated marketplaces over time.

Morphometric and morphological differences have been used extensively in the past to study domestication of the wolf and the origin of dogs. Certainly before genetic testing was performed, these methods were the only means to diverge both groups. But still now, when aDNA cannot be extracted, morphometry…

This omnibus brings together some old and some recent works by Jos Gommans on the warhorse and its impact on medieval and early modern state-formation in South Asia.

TRANSAUTOPHAGY is a European COST action to promote multidisciplinary research on autophagy and translation of knowledge to applications.

This is a joint PhD of the Faculty of Social and Behavioral Sciences at Leiden University and the Evolutionary Ecology Group at Antwerp University.

Taught from primary school to the university level – where new courses on the globalization of the Arabic writing system have cropped up (Abdallah 2014) – the Arabic script, with all its orthographic peculiarities and multiple facets, continues to shape languages other than Arabic, their communities…

Host-Microbe Interactions is one of the four research themes of the Institute of Biology Leiden.

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

Does a high quality prairie restoration in an urban/agricultural landscape provide invertebrates necessary for a sustainable ecosystem?

‘Last year, I received my Bachelor’s degree in Biology at Leiden University. During my studies I learned that I wanted to specialise in research in biophysics, microscopy, molecular and cellular biology. Now, I am fortunate enough to combine these interests in my Master’s Molecular and Cellular Life…

This project explores the decline of shifting cultivation in Northeast India. What is the impact on society of people’s deepening engagement with markets and the state?

The mission of the Plant Sciences cluster is to contribute to the sustainable production of high-quality crops, flowers and high-value bio-based products, and to contribute to the maintenance and restoration of biodiversity in natural ecosystems. This is realised by generating fundamental knowledge…

The aim is to develop methods to assess environmental and occupational exposure to (individual) pesticides, to be applied in epidemiological studies investigating pesticide exposure and human health. Furthermore, we aim to investigate the potential association between exposure to pesticides and Parkinson’s…
