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.

Mycoheterotrophy is a particular mode of life in which plants obtain carbohydrates from their associated fungal partners, instead of by using photosynthesis.

'Skill, craft, and poiesis-intensive innovation' is written by Cristina Grasseni and is published in FormAkademisk.

Mission: The Environmental Biology department aims to increase the scientific understanding of how current and emerging anthropogenic threats affect biodiversity and ecosystem services. Through this understanding they facilitate strategic management of natural resources by addressing urgent challenges…

Paul Hudson, Associate Professor of Physical Geography at Leiden University College, examines human impacts on lowland rivers in his new book.

Microbial Sciences' contribution to the Host-Microbe Interactions research theme is to investigate how beneficial or disease-causing microbes associate and interact with their host.

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.

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.

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

PhD defence

Two Leiden research projects that focus on increasing the biodiversity of Dutch production systems for food and ornamental horticulture have started thanks to funding from the Dutch Research Council's KIC research programme.

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.

Can effective synergists be identified to enhance the effect of antibiotics against Gram negative pathogens?

Both psoriasis and atheroslcerosis are diseases characterized by a chronic and systemic inflammatory profile with local lipid disturbances that alter the barrier function of the skin (psoriasis) and cause the development of atherosclerotic plaques (atherosclerosis).

Geology and Paleobotany of the Area surrounding the Archaeological Excavation at the Hazendonk River Dune (Western Netherlands).

The dissociative chemisorption of methane on metal surfaces is of fundamental and practical interest, being a rate-limiting step in the steam reforming process. The reaction is best modeled with quantum dynamics calculations, but these are currently not guaranteed to produce accurate results because…

This monograph by Robert Ross provides a detailed narrative of the Kat River Settlement in the Eastern Cape of South Africa during the nineteenth century.

In recent years, the use of primary data in terrorism research has increased. In order to maximise the benefits of this trend, we want to encourage terrorism scholars to implement open science practices more systematically. This article therefore presents different avenues towards open and reproducible…

To goal of this project is to get a deeper, more comprehensive and up to date understanding of the state of University-Business Cooperations (UBC) in Europe, from the perspective of both the Higher Education Institutions and the business sector.

The ability to create objects and structures with our hands has been essential to human development. This ability is something modern society is at risk of losing. Leiden archaeologists gather knowledge about ancient processes of ‘making and creating’ over the centuries, knowledge that helps our current…

How can we organise society so as to keep our planet habitable for us and for all other life forms around us? To answer this question, Leiden researchers collaborate across disciplines, from biology to data science, and from environmental economy to archaeology.

Research at the MCBIM group is comprised of the following research themes:

Numerous beads and pendants of amber, jet and bone have been found in Dutch Neolithic and Bronze Age context, both in settlements and in graves. Because ornaments are personal items, they are closely linked with people’s identity.

An estimated 17% of our university's total carbon footprint comes from the thousands of travel movements by our staff, students, visitors, and suppliers. Our aim is to reduce these emissions by a quarter in the coming years.

In this article, the authors explore how international criminal law is moving into a ‘post-critical’ phase and examine its potential for emancipatory reform.

Ethnography and Photography in a Moroccan Berber Village

Animal Sciences’ contributions to the Development & Disease research theme include the mechanisms and evolution of embryonic development, the development of cognitive mechanisms, and animal models for understanding mechanisms of human disease.

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…

Research into the evolutionary backgrounds of our diets can help us make the right choices in diet, health and lifestyle.

The aim of this project was to estimate emissions from lead products-in-use for the past, the present and the future and assess the development of toxicological risks associated with these products.

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.

My PhD thesis investigates the ecological significance of resistance against drought-induced air bubble formation inside the water conduits of plants (embolism), and the plasticity and functional aspects of stem anatomical traits in woody and herbaceous species.

The Oral History project, as part of the Tell Balata Archaeological Park project, published an arabic-english booklet of local stories about the site of Tell Balata. An archaeological site near Nablus (West Bank).

Creating information portals for support of European environmental policy.

Can we provide the Dutch government with an integrative framework, wherein the various policies can be placed and the need for further measures can be identified?
