Does a snake die when it bites its lip? Why will a mongoose survive a scorpion’s sting, but we humans perish? These questions occupied the minds of toxin-enthusiasts and Master’s students Biology Jory van Thiel and Roel Wouters. They collected information from many sources and published their findings…

Our institute aspires to be the center of excellence for strategic and quantitative research and education on sustainable use and governance of natural resources and biodiversity. We have two distinct research programmes: Environmental Biology and Industrial Ecology. The department of Industrial…

Living labs make it possible for citizens to participate in research for sustainable development of their environment. This way citizens, together with scientists and stakeholders, create local conditions for food production, healthy environment, and biodiversity.

Since 2013, the National Natural History Museum of the Netherlands, Naturalis Biodiversity Center, is unearthing the largest bonebed of the horned dinosaur Triceratops discovered so far. In order to answer questions about sedimentology, taphonomy and palaeobiology, palaeontologists and geologists collaborated…

It is a warm day. The sun is shining brightly while biologist Marco Roos makes his way through the bushes towards a peculiar little plant. Insects buzz, birds chirp. In the background rises the LUMC: at the Bio Science Park in Leiden, people and nature come together in a special way.

Nadia Soudzilovskaia (CML), Martijn Bezemer (IBL / NIOO) and Harrie van der Hagen (ecologist at Dunea) gave an interview to NPO1 Radio about the TERRA-Dunes project.

The mission of the Plant Sciences cluster is to contribute to the sustainable production of high-quality crops, flowers and high-value bio-based products, and to contribute to the maintenance and restoration of biodiversity in natural ecosystems. This is realised by generating fundamental knowledge…

The master’s programme Biology at Leiden University offers seven specialisations ranging from Cell Biology to Molecular Genetics. The programme prepares you for a career in research within or outside academia.

We are committed to provide you a meaningful, rigorous and quality graduate experiences in a personalized environment with a cutting edge research infrastructure and internationally renowned supervisors.

Soil biodiversity is of great importance for the maintenance of multifunctionality in terrestrial ecosystems.

How can we organise society so as to keep our planet habitable for us and for all other life forms around us? To answer this question, Leiden researchers collaborate across disciplines, from biology to data science, and from environmental economy to archaeology.

In Microbial Sciences, we perform multidisciplinary research to understand the structure and function of microbes at all levels of biological organization, from small molecules and cellular structures at atomic resolution to multicellular communities.

In September 2023, we will be transforming a under-utilised outdoor space into a greener and more biodiverse garden in which all students and staff of the Schouwburgstraat can relax and enjoy.

The soil ecosystem consists of the largest reservoir of biodiversity on Earth.
