Do natural soundscapes affect migratory decisions of fishes moving up and down rivers and is this process disturbed by vessel sounds?

Anthropogenic noise negatively affects wildlife in a wide range of taxonomic groups.

We are developing the conceptual framework, which is new to this taxonomic group, and evaluate the current state of the art with respect to all critical parameters and transfer functions for a fully developed Population Consequences of Acoustic Disturbance (PCAD) model.

The effects of anthropogenic noise on interactions between predators and their prey are still little understood.

Anthropogenic noise has been shown to affect marine animals in various ways, this may have fitness consequences at individual and population level. This thesis aims to increase insight into the quantification of sound-induced behavioural responses that are relevant to fitness, and into factors that…

Our cantilevers have a low intrinsic damping rate: this enables us to measure with low noise, since damping is proportionate to noise. However, when the magnet is close to the surface of a sample we want to study, we measure a much higher effective damping rate. This is caused by magnetic interaction…

Birds sing to be heard, but how do they cope with increasing noise levels? Which species persist in cities and why? And do they thrive or suffer in the urban soundscape?

Atoms and molecules are the basic units of matter. If we keep dividing a bar of gold or a glass of water into smaller parts, at the end we are left with a single gold atom or a water molecule.

In this thesis we use Josephson and noise scanning tunneling microscopy for the study of conventional, unconventional (iron-based) and disordered superconductors. On the one hand, Josephson scanning tunneling microscopy allows us to directly visualize the superfluid density with high spatial resolut…

To what extent is sound a stressor to fish? And are behavioural and physiological phenotypes equally sensitive to disturbance by noise pollution?

How can we develop and further improve life cycle impact assessment methods, characterisation factors and normalisation factors?

This thesis addresses questions on effectively using variational quantum circuits for machine learning tasks.

What tools can be applied to measure the output, outcome and impact of science communication efficiently and effectively?

On the 1st of October a new project funded by the Joint Industry Programme (JIP) started at the IBL on the potentially negative effects of sound on fish. Behavioural biologist and bioacoustic specialist Dr. Hans Slabbekoorn leads the international research team.

Are there acoustic cues for settlement stage larvae in deep-sea soundscapes around hydrothermal vents?

Man-made sounds in and around the oceans stress marine life and have an impact on marine species and ecosystems by changing the underwater acoustic climate. Hans Slabbekoorn from the Institute of Biology Leiden pleads for technical solutions to mitigate problems of noise pollution. Science review paper…

Leiden Law School at the heart of society

With our research and teaching, we help make the world a better place. We join in the academic and public debate, and seek answers to economic and social issues – not just at the local and regional level but at the global one too.

The Leiden University Centre for Linguistics (LUCL) aims to demonstrate its relevance to society by means of high-quality research, excellent education and various outreach activities. A few highlights:

At Leiden University, master's and advanced bachelor's students have the opportunity to take on a societal challenge alongside their regular studies, by taking on an Impact Challenge from one of the partner organisations of the Honours Academy. These can be societal organisations, municipalities and…

Fleur Visser was awarded a Veni grant by the Netherlands Organisation for Scientific Research (NWO). She is one of seventeen promising young Leiden scientists, who get the opportunity to develop their own ideas over a period of three years. Veni-funding is part of NWO's Talent Scheme, concerning…

Research from the Living Lab is important for society. For example, scientists from the Living Lab discovered that the pesticide thiacloprid is up to 2,500 times more harmful to insects than was thought on the basis of regular lab research. Partly because of this discovery, the European Commission decided…

In developing cooperation on research and education with China, Leiden University focuses on projects that promote innovation, have an impact on science, and benefit society

Below some examples of ACPA projects that have a meaningful impact on arts and society. This page will be refreshed every now and then with other projects that exhibit how arts research bears upon our perception, our understanding, and our relationship to the world and other people.

Leiden University and the city of The Hague are working closely together to increase the impact of our research and education in order to contribute as much as possible to the development of the city.

PathOS aims to contribute to a better understanding and measurement of Open Science impacts and their causal mechanisms. This is pivotal in order to develop effective OS policy in the EU (European Union). It will do so by collecting concrete evidence of OS effects, by studying the pathways of OS practices,…

Evaluating the environmental consequences of diet changes in the European Union.

The central goal of academic publishers is the dissemination of the results of research and scholarship. Their audiences can generally be divided into two categories. Academic publications are firstly made accessible to the scholarly community, so that these texts can form the input for new academic…

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

Explaining your PhD research to others can be quite difficult, especially without talking! PhD student Annebelle Kok of the Institute of Biology Leiden was one of the finalists of the 'Dance Your PhD' competition of scientific journal Science. ‘You have to understand your own research well if you are…

The majority (80%) of e-waste generated globally are recycled informally in developing countries.

Does a mid-season fire impact invertebrate populations?

The focus of this thesis is on the technical methods which help promote the movement towards Trustworthy AI, specifically within the Inspectorate of the Netherlands.

A New Technology-Based Firm (NTBF) is a significant enabler of job creation and a driver of the economy through stimulating innovation.

What impact does a mid-season wildfire have on grassland invertebrates?

On 9 January 2019, Marieke Wierda defended her thesis 'The Local Impact of a Global Court: Assessing the Impact of the International Criminal Court in Situation Countries'. The doctoral research was supervised by Prof. dr. C. Stahn en Prof. dr. L.J. van den Herik.

Identification of the products or product groups that have the greatest environmental impact from a life-cycle perspective using environmentally extended input-output analysis.

Wouter Halfwerk (IBL) received a Veni grant from the Netherlands Organization for Scientific Research for his research project on the influence of man-made noise on foraging birds.
