Plant Sciences' contribution to the Evolution & Biodiversity research theme is to understand what are the key drivers of plant biodiversity during evolution with a focus on plant life history and resilience traits and develop tools to restore and maintain plant biodiversity.

The research within the Food research programme at CML focuses on a transition towards sustainable food production and consumption systems. We investigate from a very small to a very large scale, at a local, national or international level. We do so by researching for example molecular tools, food systems,…

In 2016, CML published over 90 papers, successfully crowdfunded the Living Lab project, celebrated a royal honour for associate professor Hans de Iongh and contributed to the Global Soil Biodiversity Atlas. CML awarded five PhDs and taught students from all over the world how to contribute to sustainability.…

Ecotox is a stimulating top-facility that provides an integrative research environment around the topic of ecotoxicological testing and experimental research. Research focus: Dose-response modelling Mode-of-actions and mechanism-of-actions Test method development, in view of targets in AOPs (adverse…

Identifying natural plant-associated bacteria that provide targeted inhibition of pathogens through the production of antimicrobial peptides.

Osteoarchaeologists help forensic scientists solve crimes. They also study bone material from the Second World War in order to identify victims.

Antibiotic-resistant bacteria pose a major health threat. Addressing this challenge requires among others the development of new antibacterial compounds. The research described in this thesis focuses on discovering novel antibiotics from soil bacteria, specifically Streptomyces and Paenibacillus.Despite…

Increasing above- and belowground biodiversity in arable leek cultivation to stimulate pest control by natural enemies.

The mission of the Plant Science research programme is to contribute to the sustainable production of high quality crops, flowers and high-value bio-based products. This is realised by generating fundamental knowledge of basic biological processes related to development of plants and their interaction…

Article by Leiden University political scientist Daniel Thomas about shifting norms for membership in international organisations.

Observational, cognitive and physiological measurements in social contexts.

In this article, Friso Selten and Bram Klievink explore how public organisations strategically manage the adoption of AI.

The organisations and people who implement government policy face many different types of change. Academics from Leiden University research how they deal with these and advise them on how best to meet the needs and wishes of society.

A special relationship between plants and fungi, which plays an important role in carbon storage in soil, has the potential to slow down climate change. However, the amount of carbon stored in soil is decreasing as a result of human activity. This is what researchers say in a publication in Nature Communications.…

Did early farmers deliberately use animal manure on their fields?

Since the adoption of agriculture people have cultivated fields. The project concerns all kinds of aspects related to raising crops.

What are the key issues in conducting LCA of bioenergy systems? What is the environmental sustainability status of second generation bioethanol? How much would the final results of biogenic carbon neutrality assumptions deviate from the true values based on a complete inventory? How to assess the impact…

Yesterday, an article appeared in Biznews about the watershortages in California. David Zetland, university lecturer at Leiden University College, gives his opinion about this problem.

How can we quantify the density of species within a community through environmental DNA concentrations?

Today’s socio-economic challenges aren’t new. In the centuries after the retreat of the Roman state people with different backgrounds and with different ways of life somehow managed to build and maintain a complex economic system in northern Gaul that would produce the ruling dynasties of Europe. By…

Biodiversity is under pressure worldwide, but is essential for our health, food security and well-being. What is the influence of human actions on ecosystems? Can we provide biodiversity-inclusive solutions for our key societal challenges? These questions are central to the Biodiversity research the…

The Institute of Biology Leiden (IBL) is an internationally oriented institute for research and education in biology. We are part of the Faculty of Science at Leiden University.

The book ‘Pesticides and the Environment’ gives a transparent overview of facts and figures concerning pesticide use in the Netherlands and the impact of pesticides on the environment.

Food security is challenged by a growing global population and by climate change. Drought and soil salinity are considered the most important ones that inhibit crop yield and distribution. Worryingly, climate change is predicted to increase not only their frequency and severity, but also their co-occurrence,…

It is well-known that humans have significantly transformed ecosystems since their adoption of agriculture. However, in a deeper past, prehistoric hunter-gatherers may already have altered and modified their niche in ways that had major impacts on ecosystems.

Corrie Bakels & Hans Kamermans (eds) (2009)

The thesis describes terrestrial field trials aimed to detect side-effects of pesticides within the framework of pesticide registration procedures. Field trials were developed using vascular plants Brassica napus and Poa annua, caterpillars Pieris brassicae and effects on decomposition were studied…

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.

We aim to unravel the molecular mechanisms involved in the transformation of eukaryotic cells by Agrobacterium.

Fieldwork is an essential part of this research and of course this part of the project is also a joint effort by citizen scientists and professional archaeologists. Discover when fieldwork will take place and how you can participate.
