Leiden heeft de oudste botanische tuin van Nederland, gesticht in 1590.

A management strategy has been developed for field margins to reduce pesticide drift to non-target areas and to promote biodiversity on arable land. To this end, 3 and 6 m wide strips along the edges of winter wheat, sugar beet and potato crops have been left unsprayed with herbicides and insecticides…

In populations with a seed-bank, individuals can temporarily become dormant and refrain from reproduction until they can become active again. The repository of all dormant individuals in the population is called the seed-bank. Seed-banks are observed in many taxa, including plants, bacteria and other…

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.

Natural vanilla flavor is one of the most important in the world. However, the cost of this flavor is expensive. Production of this flavor by alternative methods, could reduce the cost.

In recent decades, climate change has led to more frequent and severe drought events, causing serious consequences such as increased forest mortality and significant crop yield losses. Understanding how drought affects plants, especially economically important herbaceous species, is crucial for predicting…

Climate change is a challenge for both current and future generations. New biological resources have to be developed in order to meet the demand for energy as well as the demand for food.

Investigating the intercultural connections that shaped practices of knowledge production in colonial Dutch Brazil.

The oldest university in the Netherlands has produced many well-known scientists. Some of them are known to the wider public; others are perhaps less well known, but their achievements are no less impressive.

Pathogenic bacteria are increasingly resistant to today’s antibiotics. Professor Gilles van Wezel seeks new forms of antibiotics in good bacteria that live in the soil.
