Economic expansion and land use cause bird extinction
Population growth, economic expansion and the associated land use caused an increase in the number of bird species facing extinction and a reduction in carbon storage worldwide. These are the findings of an international team of scientists, also from the Leiden University Institute of Environmental…

If we do nothing, more plants will go extinct
A wide range of plant species is essential to our earth because of the different materials and foods these plants provide. But plant diversity has decreased drastically in recent decades. PhD candidate Kaixuan Pan explains what we can do to increase it once again.

Hybrid zones: a quick guide by Ben Wielstra
Ben Wielstra studies hybrid zones, regions in which distinct populations of organisms meet, mate and produce genetically admixed offspring. In the journal Current Biology, he introduces hybrid zones in an accessible way.

Balanced lethal systems: a quick guide by Ben Wielstra
Ben Wielstra studies balanced lethal systems, in which half of the offspring die before birth. In the journal Current Biology, he explains in an accessible way how such a disadvantage can originate in nature.

Living legacies: Influence of plant-mediated changes in soil communities on aboveground plant-insect interactions
We examine how soil-derived legacy effects of plants structure natural ecosystems, determine aboveground plant insect interactions, and how we can use soil legacy effects to restore degraded ecosystems.

Four Leiden Scientists: 'Environmental risks of new pesticides with nanoparticles insufficiently examined'
The environmental risks of new pesticides containing nanoparticles are inadequately researched, according to four Leiden scientists in the scientific journal Environmental Science & Technology. They call for an examination of the long-term and environmental effects of pesticides containing nanoparti…

Institute of Environmental Sciences
Natural resources are becoming increasingly scarce. If we want to maintain our current standard of living, we will need inventive solutions. The researchers at the Institute of Environmental Sciences (CML) share their thoughts on how to achieve a fully circular economy in which as little use as possible…

Noise pollution affects marine life worldwide
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…

Neonicotinoids in nature: The effects on aquatic invertebrates and their role in ecosystems
This thesis describes the role of pollution, specifically neonicotinoid insecticides, as an actor of the ongoing biodiversity decline.

(Bio)diversity and sustainability
Conservation of biodiversity is one of the main challenges today. A higher degree of biodiversity results in ecosystems that can withstand adverse conditions and better provide essential ecosystem services. This is the case for both agricultural and natural systems.

Veni-grant for Michelle Spierings: ‘Do birds hear tick-tock too, or tock-tick?’
‘I did not expect to receive the grant, but it will make an amazing research possible,’ Michelle Spierings says. The researcher of the Institute of Biology Leiden (IBL) got awarded a Veni-grant of the Dutch Research Council (NWO).

Collaborating bacteria sacrifice themselves for the greater good
Like ants, termites and bees, some bacteria work together as a multicellular group. There is a strict division of labour in such colonies, to make the group more resilient to the outside world. Now researchers have found that some parts of the bacterial colony can take ‘for the greater good’ to a whole…

Student hauls in NWO grant for research into 'rejuvenating gene'
Master's student Thalia Luden receives an NWO grant for her research proposal about a gene that brings flowering plants back into a growth phase. Companies in floriculture and vegetable seed breeding also contribute to the research.

Cities have a direct influence on evolution
A global biological study has provided the most direct evidence to date that humans, and specifically cities, are the drivers of evolutionary change on Earth. Leiden University, Naturalis and the Municipality of Leiden worked on and helped fund the study.

Even a duck can parrot
That a parrot can copycat sounds is nothing new. But vocal learning is not common in animals. Researcher Carel ten Cate of the Institute of Biology Leiden (IBL) of Leiden University has now discovered a duck species that can imitate sounds. ‘It started with an obscure reference about an Australian musk…

Tropical bananaquits lose song quality in the city
I think we should go this way. This way! THIS! WAY!! Making yourself heard in a city can be difficult. That is not only the case for humans, but birds seem to be hindered by urban noise as well. Researcher Hans Slabbekoorn of Leiden University already showed that great tits in Leiden communicate differently…

Is it possible to avoid dehydration? Gene promotes wood formation
‘It was a discovery we did not expect,’ says Remko Offringa, professor of Plant developmental genetics. Today he publishes a new trait of a versatile gene in Current Biology: it makes the difference in plants between herbaceous and woody stem growth. A useful feature to prevent dehydration.

Supergenes make bizarre traits possible
Within the same species of butterfly many different wing patterns can occur. How is this possible? According to researchers Ben Wielstra and Emma Berdan, of the Institute of Biology Leiden (IBL), the answer lies within supergenes.
