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…

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

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

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

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

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…

A political-legal study of rights invocation by pollution victims in China and Indonesia

How does invasive hybridization affect threatened native species?

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

Galaxies form and evolve through close interaction with their surroundings. As a result, the heavy elements ('metals') that are synthesized in stars, are found both inside and outside galaxies.

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.

Electric noise can be useful for scientists but inconvenient for chip manufacturers. They do share a wish to predict the amount of noise. PhD student Sumit Tewari overturns a century-old law relating noise to current. He defends his thesis on March 27th.

On 17 October 2019, Laure d'Hondt defended her thesis 'Addressing Industrial Pollution in Indonesia. The Nexus between Regulation and Redress seeking'. The doctoral research was supervised by prof. A.W. Bedner and dr. J.A.C. Vel.

Two PhD defences on 9 June by behavioural biologist Errol Neo and underwater acousticianan Özkan Sertlek relate to measuring noise in the North Sea and the harm this noise can do to aquatic animals and their surroundings. Little is known about how harmful human noise can be to aquatic animals.

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.

We perform multidisciplinary research at molecular, cellular, and organismal levels of animal biology to increase fundamental understanding of health and disease.

Using the principles of Industrial Ecology in Environmental Policy making in two cases: transition to a hydrogen economy and chlorinated compounds.

Fishes rely heavily on sound to find their way during migration or dispersal. Many species are affected by noise pollution. Hans Slabbekoorn from the Institute of Biology Leiden received a HORIZON2020 grant of 500,000 euros to study the impact of sound conditions on movement decisions of fishes.

Hans Slabbekoorn, researcher at the Institute of Biology Leiden, is one of the editors of the latest volume of the Springer Handbook of Auditory Research (SHAR). This book is filled with everything known about the effects of sound on vertebrates. Slabbekoorn’s contribution to the book as a co-author…

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?

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…

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.

This thesis combines field and laboratory studies to address some of the most pressing questions in the field of microplastic research.

It may well be possible to remove nitrate from polluted groundwater and at the same time produce ammonia in a sustainable way, according to PhD candidate Phebe van Langevelde and Professor Marc Koper of the Leiden Institute of Chemistry in Joule on 26 January. Together with a German colleague, they…

Human activity at sea makes a terrible racket. To what extent does this disturb marine animals? PhD candidate Annebelle Kok studied the effect on harbour porpoises, long-finned pilot whales and their prey, and discovered the sheer complexity of the problem. PhD defence on 12 November.

This year Leiden University exists for 444 years! This will be celebrated together with the residents of Leiden and The Hague during various activities. One of these is scientists and residents doing research on plastics and psychology together.

On Friday evening 8 June, Thijs Bosker, Associate Professor at Leiden University College (LUC), was on television in NOS Jeugdjournaal about plastic pollution and microplastics

Do e-waste workers display enhanced effects of adverse health effects due to informal e-waste processing in Nigeria? Is there a difference between the health outcomes of the exposed and the control groups? Are there difference in health effects within and between job groups (collectors, dismantlers,…

From 26 to 29 September 2017 the International Conference on Microplastic Pollution in the Mediterranean Sea was held.

On Friday morning, 8 June, Thijs Bosker, Associate Professor at Leiden University College, was interviewed by NPO Radio 1 on plastic pollution in Antartctica: ''Anually, an additional 4 - 12 billion kilos of plastic ends up in our ocean''.

Scientists and non-scientists co-creating breakthrough citizen science projects for measuring, understanding, and mitigating air pollution. That’s what happened during the first international workshop of the newly established Citizen Science Lab from 22 until 26 January at the Lorentz Center at Leiden…
