The most urgent sustainability challenges, such as climate change, biodiversity loss, resource depletion, and pollution, are complex issues that concern society as a whole. This means that among employers there is a growing demand for graduates who are able to combine both natural scientific and social…

Why do plants produces always produced so many slightly differing metabolites within a particular chemical class?

How do balanced lethal systems originate and persist in nature?

Does a moving hybrid zone leave a genomic footprint?

Reseachers of the Institute of Environmental Sciences Leiden (CML) have contributed to a debate in the Journal Nature over whether lions in Africa can only be saved with dollars and fences.

In this thesis I examine how soil biotic and abiotic characteristics change and interact throughout the course of afforestation and how they subsequently impact tree performance.

Farmers on the outskirts of Nairobi National Park protect their livestock using flashing lights on top of the animal enclosures. This system keeps lions away at night. Leiden research has shown that the method is both simple and effective. Publication in PLOS ONE.

Coral reefs throughout the world are under threat. After studying the reefs in Malaysia, Zarinah Waheed concluded that there is room for improvement in coral reef conservation. PhD defence 22 November.

This thesis aims to address offshore wind energy (OWE)-related environmental impacts.

In our lives we often have little attention or appreciation for plants, let alone the ones we commonly call weeds. This inattention for plants has been described as plant blindness. The Stoepplantjes project aspires to decrease plant blindness by changing the image of weeds and using citizen science.…

Bacteria and fungi on organic dairy farms are significantly different from those on conventional farms. That was discovered by postdoc researcher Sofia Gomes and her supervisors Nadia Soudzilovskaia and Peter van Bodegom in collaboration with the Louis Bolk Institute and Naturalis Biodiversity Centre.…

Biodiversity enables ecosystems to thrive through the synergy of functional differences among organisms. While human well-being strongly depends on biodiversity-driven ecosystem services, human actions are also at the root of current unprecedented biodiversity declines.

Last Monday April 18, Bram Koster (professor at the Institute of Biology Leiden (IBL), professor at the Leiden University Medical Center (LUMC)) and Ariane Briegel (professor at the IBL) gave a presentation to the mayor of Leiden, Henri Lenferink. The presentation took place at NeCEN, the open access…

Recently a Memorandum of Understanding (MOU) was signed between the Institute of Environmental Sciences (CML) - Leiden University and the Mulawarman university in Samarinda, Kalimatan province, Indonesia. The MOU will be effective for a period of five years and covers the intention to collaborate in…

‘Make more room for nature on farmland and you'll be surprised at the result.' This was the advice from Geert de Snoo in his Dies lecture.

To what extent does human intervention influence the world’s biodiversity? And can we predict how biodiversity and ecosystems will change in the coming years? Inaugural lecture by Peter van Bodegom, Professor of Conservation Biology, on 8 May.

What are key regulators of plant ageing that can reverse ageing in plants (rejuvenation), and how can we use this knowledge to improve crop plants?

Universities cannot survive in this highly competitive world without collaboration. And the ultimate aim is to make the world a safer and more sustainable place. This was Rector Carel Stolker’s message during the 441st Dies Natalis.

For nine years he worked on the three-volume standard work Plant Galls of Europe. It yielded 2300 pages about 10,000 species of European galls, abnormal outgrowths in plants caused by parasites. Hans Roskam from the Institute of Biology Leiden: ‘The abundance of galls says something about the natural…

How does climate change affect the migration routes of birds? Mainly negatively, according to a new study from Yali Si from the CML. ‘It changes the timing of natural events differently in each region,’ she explains. ‘This can lead to a growing mismatch between the availability of food and the supposed…

The League of European Research Universities (LERU) calls for greater appreciation of fundamental research that does not have an immediate application. A working group headed by Geert de Snoo, dean of the Leiden Faculty of Science, issued a memorandum on the subject on 29 August.

After seven years, the Faculty of Science said goodbye to Geert de Snoo as dean During on 29 August. This happened with a pub quiz, a special edition of Our Talents & Discoveries and no less than two decorations. Take a look at the pictures for an impression!

On Thursday the 24th of November, Tseard Hoekstra and Jeroen Ververs (members of the delegation Holland Rijnland), Geert de Snoo (Dean Faculty of Science), Martina Vijver (CML), Herman Spaink (Scientific Director IBL) and Klaas Vrieling (IBL) explored possibilities for collaborations between companies…

Farmers who commit to environmentally friendly working methods also actively practise nature conservation in their farming - particularly when this is not financed by the government. These are the findings of research carried out by Anne Marike Lokhorst, who will receive her PhD on 17 September based…

Management of Impacts on Biodiversity: What are the effects of light pollution from cities and bridges and noise pollution from passing vessels and nearby road traffic on migratory fish passage and spawning in rivers?

Primate and test specialist Jane Goodall paid a visit to the Hortus botanicus in Leiden on 21 May for a ‘meet & greet’. Goodall, a world-famous researcher and nature protectionist, was presented with an orchid named after her and used the occasion to draw attention to the issue of plant protection.…

In developing cooperation with Indonesia, Leiden University focuses on projects that benefit culture, nature, society and economy, in Indonesia as well as in the Netherlands.

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.

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.

On December 4th, Flor Rhebergen received the 2015 Unilever Research prize for his study achievements at the IBL for his outstanding work in the field of Evolutionary Biology. Flor Rhebergen received the “Ovum” sculpture and was awarded €2.500.

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.

Funded by NWO, 'Futuring Heritage: Conservation, Community and Contestation in the Eastern Himalayas' explores how environmental conservation initiatives in the Eastern Himalayas intersect with the cultural expectations of ‘indigenous’ ethno-linguistic minorities.

The plant hormone auxin plays a central role in the growth and development of plants. Auxin acts in a concentration dependent manner and polar cell-to-cell transport of this hormone determines its distribution in the tissues of plants. This polar auxin transport is mediated by several families of auxin…
