Pim de Voogt in AT5 about the soil pollution in the Amsterdamse Bos
Local medium At5 has an extensive article and TV report about soil pollution in the Amsterdamse Bos and how the municipality of Amsterdam is keeping quiet about this. Emeritus professor of environmental chemistry Pim de Voogt (UvA-IBED) is concerned about the possible health effects of the substances found and calls for more research.
Evy van Berlo in De Volkskrant about Bonobos
Bonobos were already known as friendly monkeys. A new study from Harvard University of the monkey species in the wild shows that they also work together with monkeys that do not belong to their own group. They groom each other, make friends and share food. IBED Scientist Evy van Berlo comments: 'If food is not scarce, you don't have to fight for it. Bonobos evolved in an area where there was usually enough food. Then aggressive behavior is undesirable.'
Karline Janmaat and Henkjan Honing in NRC about the research by into the role of music among BaYaka women

Franciska de Vries on the NPO1 television program "Govert to the core of the earth"
Episode five of the popular science television program "Govert to the core of the earth" focuses on the 'living planet'. Govert Schilling discusses the origins of life on earth. One of the scientists he speaks with is Franciska de Vries. The camera crew spent a lot of time at a field experiment in the Veluwe, where Francisca de Vries and her team are investigating how much CO2 the vegetation on site absorbs from the air, what the vegetation (and soil life on site) emits and how this affects everything. Francisca also explains how plants have created a fertile, organic soil layer on the earth's crust.
Maja Bradarić in Trouw about the shut down of offshore wind farms during 'heavy bird migration'
This spring, experiments were carried out for the first time with the 'start-stop system' in the offshore wind farms at Borssele and Egmond aan Zee. Based on a calculation model on bird migration by Maja Bradarić and additional advice from bird migration experts. After this successful trial, the 'start-stop protocol' in wind farms in the North Sea will really start this autumn. When there is a strong migration of birds, the wind turbines almost go out.
Piet Verdonschot in regional newspapers about midges and the spread of bluetongue
The midge from the suborder of mosquitoes comes in more than 6,000 species and lives all over the world. There are more than 300 different species of midges in the Netherlands alone. Not all of those species sting and of the species that do, only the females do it. They sting people and animals because they need a 'blood meal' to develop their eggs. Some species can transmit viruses to other animals when they sting. " A midge looks very different from a mosquito. It is much smaller and has the shape of a fighter jet," says Piet Verdonschot "If you are bitten by a mosquito, you can sometimes kill it in time. With a midge you won't be able to do that. The moment you feel the sting, it is already gone."
Various media reports on the research on Bewick’s swans choosing wintering areas based on the weather
Bewick’s swans fly less far during their autumn migration when the weather is warm. Climate change has therefore led to a shift in their common wintering areas.

A lot of media attention for nitrogen research IBED
On September 12, the highly anticipated report by Albert Tietema and Emiel van Loon was published regarding their research into the spatial distribution of nitrogen deposition around dairy farms. The report received a lot of media attention, and it was striking that various media gave their own interpretation to the research. In an interview with Folia, the researchers also discuss these incorrect interpretations. According to them, the results do not mean that buying out peak loaders is useless, or that this study puts a bomb under the government's policy on nitrogen. In the trade journal Boerderij, Tietema also addresses the (unjustified) claim that the research shows that the RIVM's OPS model significantly overestimates nitrogen deposition.
Annemarie van Wezel about PFAS on Radio1 and with Mohammed Sadia on Follow the Money

In addition, she and Mohammad Sadia recently spoke with the investigative journalism platform Follow the Money about the PFAS problem.
Roos Kentie in the Leeuwarder Courant about the migratory behavior of the lesser black-backed gull
Flying further does not ensure a higher chance of survival or breeding success during the migration of lesser black-backed gulls, according to research by IBED together with NIOZ. The Leeuwarder Courant paid attention to the study and spoke about it with Roos Kentie.
Mark Vermeij in Friesch Dagblad about the important role of Parrotfish for the tropical, white sand beaches
Mark Vermeij's research showed how important some fish are for the survival of coral reefs. Take the parrotfish, a species that likes to eat algae. “Due to an excess of nutrients in the water, you sometimes get competing algae to bloom, which means that corals don't have room to grow. Therefore, provide a good population of herbivorous (plant-eating, MK) fish, such as parrotfish, and a reef's chance of recovery increases enormously. So don't fish it all out."
Annemieke Drost in Haarlems Dagblad about her research into blue-green algae
In the course of every summer, the quality of bathing water is a thorny issue. Researchers from the University of Amsterdam come to the Veerplas near Harlem to conduct research into blue-green algae. Annemieke comes to Spaarnwoude every week to take samples. She is still busy with her research, but confirms that there are blue-green algae in the water.
Mark Vermeij in the Reformatorisch Dagblad about how coral suffers from the current high water temperatures
The sea water in the Caribbean recently rose above 38 degrees in some places. Mark Vermeij explains in the Reformatorisch Dagblad what this does to the local coral reefs.

Henry Hooghiemstra in NRC about the phenomenon of 'tree line'
The widely accepted concept of 'the tree line' - the boundary in, for example, the mountains or in the direction of the North Pole above which no more trees can grow - is less simple than it seems. NRC has a background article about the fact that it is less easy to say exactly where the tree line is than you might think. One of the experts who will be speaking is Henry Hooghiemstra (UvA-IBED).
Crystal McMichael and William Gosling in Nature Today
In certain areas in the Amazon, forests that were altered by humans during the past several hundred years may contain higher abundances of plant species that are more resilient to modern fire or drought events. This is the message of a new perspective paper in the scientific journal People and Nature by Crystal McMichael and William Gosling.
Astrid Groot in Newswise
Astrid Groot is among the team of researchers from the UvA and North Carolina State University that made a significant discovery. They successfully pinpointed the precise combination of pheromone chemicals employed by male moths during their courtship rituals. This breakthrough sheds light on the intricate chemical blend utilized by both male and female moths within this moth group for essential short-range communication. The results of their study were published in the esteemed scientific journal Current Biology.
Gerard Oostermeijer in Het Parool about the research in the Amsterdam Water Supply Dunes
After years of being eaten bare by thousands of fallow deer, nature in the Amsterdamse Waterleidingduinen is slowly recovering. Sixteen landscaped exclosures in the nature reserve should provide insight into the recovery of the flora and fauna without the presence of the hungry deer. The research is approached on a large scale: ten researchers with various specialisms keep an eye on developments within and outside the exclosures with volunteers. One of them is Gerard Oostermeijer, who specializes in the ecological effects of endangered and invasive species, in this case a large grazer with an insatiable appetite for rare flora.
Verena Schoepf in Spiegel Online about how heat could lead to massive coral bleaching
Heat waves are currently occurring in many regions around the world. In many ocean regions, this could lead to major coral bleaching in the coming months. "The fact that sea temperatures are so high so early in the summer is extraordinary," Verena Schoepf told the Science Media Center (SMC). "Many coral reefs in the Caribbean are already severely depleted and only have a few corals left. In the coming weeks and months, coral reefs in the northern hemisphere in particular are at greater risk of bleaching."

He expects that due to climate change we will increasingly have problems with blue-green algae in recreational lakes.
What will the planned offshore wind farms do to our birds?
It is important to limit the impact of new offshore wind farms on birds as much as possible (the choice of location for wind farms, additional measures and constant research and monitoring help reduce the number of victims among birds at sea). For example, the University of Amsterdam made a model to predict the flight of migratory birds and to determine in which nights the largest part passes. At those times, the blades can be stopped in advance.
Ian McFadden in Nature Today about past climate helps explain why there are no kangaroos in Bali
A new model clarifies why millions of years ago more animal species from Asia made the leap to the Australian continent than the other way around: the climate in which the species evolved played an important role. This study was published by the renowned scientific journal Science on 7 July, with two co-authors from the Universities of Amsterdam and Utrecht.
Willem Bouten in newspaper AD and regional newspapers about birds & windmills
Daily newspaper AD has an article about bird collisions with windmills. Willem Bouten (UvA-IBED, emeritus) speaks in it.

Various media reports on wind energy curtailment over the North Sea for the conservation of migratory birds
Researchers at IBED are developing methods to quantify and predict bird migration in collaboration with different stakeholders. A predictive model developed by Maja Bradarić, together with Bart Kranstauber, Willem Bouten and Judy Shamoun-Baranes during her PhD, is now part of protocol for wind energy curtailment over the North Sea developed by Rijkswaterstaat for the Ministry of Economic Affairs and Climate Policy. The protocol was tested for the first time at two offshore windparks near Borselle and Egmond aan Zee on 13 May 2023. The research is part of the Open Technology Programme, project Interactions between birds and offshore wind farms: drivers, consequences and tools for mitigation (project number 17083), which is financed by the Dutch Research Council (NWO) Domain Applied and Engineering Sciences, in collaboration with the following public and private partners: Rijkswaterstaat and Gemini wind park
Various media reports on the decrease in nitrogen deposition in dunes, leading to less grass growth
The deposition of nitrogen in the dunes has decreased considerably since the early 1990s. This has led to less high and less dense grass mats in the dune landscape. Good news, because the soil now receives more sunlight, which offers opportunities for the dune pansy, the dune heron's bill and other species that belong in the Dutch dunes. However, species richness has not yet been restored. This has emerged from new research by Annemieke Kooijman in collaboration with Waternet Amsterdam.
Emily Burdfield-Steel about 'smart bird houses' that register what bird youngsters eat

The aim of the research is to gain more insight into blue-green algae and the toxins they produce. The local newspapers of the AD group, among others, reported on this, as did the program Early Birds, and De Telegraaf also published a (very concise) report
Scientific research into microfibers is not possible without citizens
Washing clothes may be cool for us, but not so nice for the surface water. Every wash of synthetic clothing releases plastic microfibers that are bad for the environment. At the University of Amsterdam, an entire team has conducted research into this with the help of so-called 'citizen scientists'. In the lab you can't really imitate washings that we all do every day. Bernou Boven is one of the researchers.
Migration distances of lesser black-backed gulls do not influence their success
'Look, there's F.AXF. In any case, it's back!" When gull researcher Roos Kentie walks into 'her' gull colony on Texel for the first time this year, she almost automatically looks for familiar birds. At first glance, she cannot easily tell the different herring gulls and lesser black-backed gulls apart, but thanks to the colored rings with letter codes, which a few dozen of the many hundreds of birds wear on one of the legs, some gulls do become 'old acquaintances'.
Annemarie van Wezel in the Nederlands Dagblad about PFAS in our everyday products
The Nederlands Dagblad has an article about the health effects of PFAS and how you can avoid coming into contact with these chemical compounds. They are present in many everyday products, from shower gel and make-up to frying pans and certain foods. One of the experts speaking is Annemarie van Wezel.
Toilet paper is an unexpected source of PFAS in sewage
American researchers have found an unexpected source of PFAS in sewage: toilet paper. These harmful substances in our sewage water eventually end up in the surface water again, with adverse effects for ecosystems and humans. Such research is also being carried out by, among others, Skylar Xie and Ioanna Gkika in the research group of ecotoxicologist Michiel Kraak . All three agree that the results of the American study mainly confirm what we already knew: PFAS are everywhere, including in household products
Franciska de Vries in NRC about the reliability of Agrifacts
Daily newspaper NRC has a critical article about the organization Agrifacts, supplier of information about the agricultural sector to political party BBB, among others.

Annemarie van Wezel on RTL News about PFAS in the blood of animals and humans
PFAS compounds have been found in the blood of more than 330 animal species in the wild, according to a new report from advocacy organization Environmental Working Group (EWG). Annemarie van Wezel (UvA-IBED) calls this 'alarming' in an article on RTL Nieuws. According to her, it shows how persistent PFAS are.
Carina Hoorn in Het Parool and New Scientist about the rapid deforestation of the Amazon
Humans are destroying the rainforest at such a rapid rate that natural recovery processes can no longer keep up. “Our main concern is that deforestation will reach a tipping point where the forest can no longer recover,” says earth scientist Carina Hoorn, who was involved in the analysis.
Millions of kilos of extra nitrogen, because farmers illegally take land
Much more biodiversity restoration is possible along field margins, says Kenneth Rijsdijk. Then hedges should return.
Jorin Veen on Radio 1 about the evolution of human brains
Student Jorin Veen recently graduated cum laude with Karline Janmaat (UvA-IBED) for research into the evolution of human brains. According to him, the unusual size of our brains has to do with the way we used to collect food. He talks about this in the Radio 1 news.
Bernou Boven on NPO radio about microplastics from laundry
The number of microplastics in our living environment is increasing daily. Not only should more research be done into the shared effects of this, but we should also look at how we can reduce our emissions, reports TNO. Bernou Boven explains in the radio program "Vroege Vogels" whether we can adjust small things in our washing behavior, so that fewer microplastics are released in the washing machine.
Amazon deforestation may be irreversible
The rate of deforestation in the Amazon is greater than previously thought. There is therefore a risk that a threshold value will be reached, after which the ecosystem will change irreversibly. And that could have catastrophic consequences for the global climate system, writes a UN panel of leading scientists on 27 January in Science. Carina Hoorn is one of them. 'Man's influence in the Amazon is now so great that the natural processes in an area of millions of square kilometers have no time to recover.
Amazon at the limit: one third damaged, two thirds endangered
The rainforest on the Amazon is home to around one tenth of all known plant and vertebrate species on earth. Human activity could seal its demise. On December 13, 2022, Maja Bradarić was promoted to the other bird trek on the Noordzee and the mogelijkheid die trek te Voorspellen. Rijkswaterstaat had the University of Opdracht given for the separate area. Het voorspellingsmodel dat dit onderzoek heeft vororttzt is a relevant part of a curtailment procedure for wind energy at sea: het (nagenoeg) stopzetten van wind turbines zodra er massale vogeltrek over sea op rotorhoogte wordt monitored.
How many microplastics are released during a wash?
Antonia Praetorius, Lies Jacobs and Bernou Boven are leading a public survey that checks how many microplastics are released during the washing of clothes in an average Dutch household. Daily newspaper "Trouw" visited their lab at the Amsterdam Science Park.
Bonobos are more interested in strangers' emotions than familiar ones
A new research shows that both bonobos and humans are more interested in photos of conspecifics showing emotion than in neutral photos. But while in humans our attention is drawn to photos of people we know, in bonobos attention is more quickly drawn to the emotion of individuals unknown to them.
New bird prediction model can contribute to fewer bird casualties from offshore wind farms
On 13 December 2022, Maja Bradarić obtained her PhD on the subject of bird migration in the North Sea and the possibility of predicting that migration. Rijkswaterstaat had commissioned the university to carry out this study. The prediction model that this research has produced is an important part of a curtailment procedure for offshore wind energy: the (virtually) shutting down of wind turbines as soon as massive bird migration over the sea at rotor height is expected.
