IBED researchers frequently appear in the media to present their research and its applications to a wider audience to strengthen the link between Science and Society. Here you can find an overview of IBED research that appeared in magazines/newspapers or was broadcasted on radio/TV (mainly in Dutch).
Newspaper De Volkskrant published the 21 most spectecular science images of 2021, including an explanation by 21 scientists. IBED professor Annemarie van Wezel comments on a picture with floating plastic, and explains why the plastic particles that can't be seen are even more of a risk to our environment.
In recent years, periods of extreme drought and extreme rainfall have alternated at a rapid pace. It is getting wetter and drier. With consequences for nature, agriculture, our dikes, our houses and ultimately for ourselves. The question is: how do we keep the Netherlands wet, but not too wet? These questions were discussed in the podcast 'De Oplossers' with amongst others IBED professor Annemarie van Wezel.
Folia called the employees behind the UvA Fossil Free action group, including IBED researcher Peter Roessingh, the UvA employees of the Year 2021. They fought for a fossil-free pension for academics, and got it done.
Concerned residents in the vicinity of the wastewater injection in Twente, united in the Stop Afvalwater Twente foundation, have started a petition. The aim is to collect as many signatures as possible, so that it becomes clear to the minister that Twente no longer wants chemical pollution in the soil. IBED emeritus professor Lucas Reijnders says: 'It's a poisonous cocktail, what they've done is wrong.'
What is the largest living organism in the world? A fungal network on which the honey fungus grows. A network of 1500 football fields in size. IBED researcher Vincent Merckx explains on Radio 1 (Belgium).
Several media reported about a new publication of IBED researcher Fleur Visser on Risso's dolphins that can perform impressive twisting dives that let them 'drill' through the water to depths of more than 1,970ft to catch prey.
Photographer and film maker Jan van IJken made the 'Planktonium', about the misterious world of plankton. IBED researcher Katja Peijnenburg tells about these tiny creatures on radio Vroege Vogels.
The principle seems simple: carbon stored in the soil is not released into the air as the greenhouse gas CO2. But how big is this contribution? Too small to stop climate change. It makes more sense to look at the organic fractions in the soil, which sometimes take decades to break down. Keeping farmland covered with vegetation all year round, not tilling it too intensively, catch crops and green manure crops all contribute to retention of organic matter and nitrogen, that other elephant in the room. 'No plants, no nitrogen uptake,' says Professor Franciska de Vries.
For more than a century, it collected dust in a drawer in the museum. But now it has revealed its secrets after all: Bas van Geel has extracted grains of pollen from a mummified dropping of a Chilean giant ground sloth, which tell us everything about the animal's diet and the landscape in which it lived.
Cleaning products can be found in every home, from abrasives and grease removers to washing-up liquid and bleach. Professor Annemarie van Wezel expects that higher concentrations of chemical substances have been released into the environment as a result of the extensive cleaning during the corona crisis.

With the continuing poor water quality in the Netherlands, a crisis similar to the current one involving nitrogen is in the making. Three professors, including Annemarie van Wezel, warn of this.
In recent years, ecologists from the Royal Netherlands Air Force, KNMI and the University of Amsterdam (Judy Shamoun-Baranes) have recorded unusual flights of thousands of birds on New Year's Eve on radar, where you can see birds taking flight in response to fireworks. If fireworks are set off all over the country at the same time, the birds have nowhere to go.
'With an apple drill, I took a piece of the turd with a diameter of one and a half centimetres,' says Bas van Geel. 'From that, I was able to prepare intact pollen grains. (...) The giant sloth turned out to have eaten a meal of lots of strawberries and cushion plants!'
Gender does not matter in the Guinea baboon when it comes to leadership success, researchers conclude after two years of monkey watching. Primatologist Serge Wich thinks the next step is to study this in more primate species and determine whether social relationships have the same influence in those species.
Jan Willem van Groenigen and Franciska de Vries tell columnists and others: our agricultural soils are not dead at all.
The Netherlands has an enormous task to restore nature. A substantial reduction in nitrogen deposition is necessary for this. The concept of the critical deposition value (kritische depositiewaarde) plays an important role in nitrogen policy. In this article, Franciska de Vries and colleagues briefly explain what the concept entails and why it has become so important.
The popularity of water filters seems to be increasing in the Netherlands. According to the manufacturers, they purify tap water of heavy metals and bacteria. Experts, such as Annemarie van Wezel, unanimously reject the devices. It is pure deception.
In the entrance to the Noordzeekanaal near the port of IJmuiden lies an island: Forteiland. Here a gigantic gull colony with about a thousand pairs of lesser black-backed gulls and about a hundred herring gulls breeds. Since 2019, Rosemarie Kentie has been collecting feather and blood samples from herring gulls and lesser black-backed gulls that breed on Fort Island. By looking at the composition of the blood, Rosemarie can determine whether gulls have eaten food from the sea or from the land.
Many species are at risk of extinction, and due to climate change, more and more are becoming so. But is that actually a bad thing? And could humans become extinct as well? In this episode, biologist Gerard Oostermeijer of the University of Amsterdam, among others, discusses biodiversity, environmental philosophy and the future of humans.

The dodo has long been extinct, but the flightless bird still lives on in illustrations. Scientist Alexandra van der Geer (Naturalis Biodiversity Center) studied it together with Kenneth Rijsdijk of IBED.
To answer this question you can look at the vomit balls, with undigested fish remains (or spare ribs) that you find next to a gull's nest. But it can also be done in a modern way, says IBED researcher Roos Kentie in Vroege Vogels: 'The type of food of a gull, land or sea, high or low on the food chain, leaves its mark in the bird's blood!'
You wouldn't say it these days, but in recent years the Netherlands had warm and dry summers in due to climate change. The prospect is that this will happen more often. Folia spoke to IBED professor Franciska de Vries, who is investigating the effects of climate change on ecosystems and the soil: 'The most important thing is good soil management.'

Every spring sprayed fields are a reason to start the discussion about the use of glyphosate. This is why producer Bayer instructs farmers to get rid of dead plant stuff as soon as possible after use. IBED Prof. Annemarie van Wezel points out in newspaper De Volkskrant that it is inevitable that glyphosate from the farmladen ends up in ground, runoff and adjacent ditch water.
In Artis Zoo, on the edge of the elephant enclosure, an advanced radar has recently been installed that counts the birds, insects and bats that are flying over day in, day out, 24/7. 'Because the device also looks at the wing beat, it even sees the difference between, say, a gull and a duck,' explains IBED Professor Judy Shamoun-Baranes on Vroege Vogels Radio.
Airborne laser scanning creates high-resolution 3D images of the landscape. IBED researchers Szófia Koma and Daniel Kissling in collaboration with the Dutch Butterfly Conservation used these data to study the habitat preferences of butterflies.
