Mycorrhizas are symbiotic associations between soil fungi and most plant species.

Bacteria are highly complex and diverse organisms that have adapted to survive in ecological niches ranging from the most extreme to the most heterogeneous environments.

The use of N fertilizers has increased worldwide in the past century. While this increased input of N has increased food productivity, it has also contributed to decreases in biodiversity, soil quality and environmental health, including increases in greenhouse gas emissions.

Marine sponges are important members of reef ecosystems, as they play ecological roles that are essential for the health of the reef.

How do genetic and environmental factors make us vulnerable to depression?

This study focused on how households' food consumption and waste were adapted to lifestyles during COVID-19.

In this PhD study, I aim to deepen our understanding of the influence of major mycorrhizal types, namely arbuscular mycorrhizae (AM) and ectomycorrhizae (EM), on the global soil carbon cycle and their potential distribution changes under future environmental shifts.

The institute is lead by the Scientific Director, prof.dr.ing. Martina G. Vijver, Director of Operations: Drs. Paul C. de Hoog and Director of Education Dr. Stefano Cucurachi in collaboration with the Management Team.

Do you want to be an intermediary between the scientific experts, policy makers and politicians in the domain of sustainability?

The Council of State in the Netherlands gave a ruling in the so-called Porthos case which revolves around the exemption currently in place for nitrogen emitted during the construction of major projects such as housing. The Administrative Law Division of the Council of State ruled that the partial construction…

Computer scientists from Leiden University and the University of Münster describe a new theoretical starting point for approaching difficult optimization problems. They can take into account several criteria simultaneously, instead of just one at a time.

Short description about 20th anniversary of CEDC, the fieldstation in Cameroon, and 20 years of cooperation between Leiden University with the University of Dschang in Cameroon.

Astronomer Donggang Wang, physicist Anne Meeussen and chemists Nick Gerrits and Elliot Mock: all four are receiving a Rubicon grant from the Dutch Research Council (NWO). This grant for young talent will enable them to spend two years doing research at a foreign university.

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.

There are eight institutes at the Faculty of Mathematics and Natural Sciences:

Celebrating 20 years of Environmental Research and Education in Northern Cameroon

Experimentalism has emerged as a prominent approach for addressing environmental problems. Christopher Ansell (Berkeley) and Martin Bartenberger (Leiden University) survey the diversity of experimentation methods, identifying their strengths and weaknesses, and suggesting possibilities for fruitfully…

Celebrating 20 years of environmental research in Cagayan Valley and Sierra Madre

Security and safety challenges rank among the most pressing issues of modern times. Challenges such as cyber-crime, terrorism, and environmental disasters impact the lives of millions across the globe. The course will introduce you to this broad theme in an increasingly complex world.

In this course, you will learn about sustainability and staying with the environmental boundaries of our planet. You will gain an understanding of the effects of growing affluence and population growth, the key challenges we are facing, and ways to influence your direct environment.

Some examples of AI-research done at Leiden.

Leiden University’s European and International Business Law programme has been successful for more than 20 years. Read more information about the benefits.

As a graduate of Dutch Studies, you will be fluent in the language and will have gained insight into the mind-set and culture of the Netherlands. This is the perfect preparation for working in international organisations with Dutch connections, in governmental organisations or NGOs, in Dutch educational…

How have human-environmental entanglements changed in the Gulf of San Miguel, Darien, Panama, from the first traces human practices through to the present?

Op dinsdag 15 oktober 2024 nam Rogier Kegge, universitair docent Staats- en bestuursrecht, deel aan de zogenoemde technische briefing van de vaste commissie voor Infrastructuur en Waterstaat over het voorzorgsbeginsel.

To be eligible for Industrial Ecology at Leiden University and Delft University of Technology, you must meet the following admission requirements.

Plant architecture has distinct forms in different plant species, but also within a species the finalarchitecture of a plant is determined by its gradual development and changes therein induced by environmental conditions during the plant’s life cycle.

Ichthyoarchaeological and biomolecular research to assess the trophic ecology of the Rhine-Meuse delta in the Holocene

Throughout all domains of life, from bacteria and archaea to eukaryotes, genomes adopt well-organized three-dimensional structures that can change in space and time to accommodate preferred transcriptional programs for environmental adaptation, the maintenance of cellular identity and differentiation…

The HARVEST project explores the dietary choices that our hominin ancestors and relatives made, by recovering information on what they consumed, and how factors like environmental variation, intrinsic biology, and development of food processing technologies could have influenced their decisions.

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?

The role of material production as a driver of environmental impacts is increasing, which calls for a better understanding of global material flows. This thesis explores the role of in-use stocks of products, buildings and infrastructure as a key driver of global material demand and discusses the implications…

Environmental humility is integral to addressing the climate crisis, but humility can also lead to political domination. How can humans relate to nature more humbly without risking domination?

From nanoparticles to colliding ice planets and from biological origami to new x-ray scanner techniques: this year again, our scientists have made wonderful discoveries. From the largest numbers to the smallest molecules and from the oldest galaxies up to the latest algorithms, take a look at each institute's…

Why are not all children equally responsive to variations in the social environment?

This study focuses on the local level impacts of a highly globalised industry: the international trade in tropical timber.

The Brazilian economy has long been defined by its enormous potential. Over the past 30 years, some of this has at last been realised. Latin America’s largest economy has rapidly risen in global importance while poverty at home has declined. Yet, despite periods of progress, Brazil remains prone to…

Bacterial chemosensory arrays are protein assemblies that are the key structural and functional component for motile bacteria to sense their internal or environmental chemical signals.

What are relationships between student teachers’ personal characteristics, learning experiences and perception of external environmental aspects impacting teacher career and their commitment to teaching?

After graduation you have a lot of opportunities: the field of science communication is very broad. You can also aim for a career in industry or research.
