Hybrid zones occur where two species meet and produce offspring (hybrids). Typically, hybrids show a considerable reduction in fitness. In this thesis two hybrid zones are treated.

Evolution is all around you every day. This is the message of the new Massive Open Online Course (MOOC) of Leiden University and Naturalis that begins on September 19.

Is it possible to synthesize industrially relevant compounds in a sustainable manner through the use of light-capturing cyanobacteria?

Some MPs are very active, while others are not. The number of proposals and questions that MPs in the Netherlands put forward is determined in part by the level of activity of their fellow committee members rather than by electoral incentive, which is the case in other countries.

This thesis describes the synthesis and biochemical evaluation of a variety of cyclophellitol based activity-based probes and inhibitors targeting various endo- and exo-acting retaining glycosidases. In the last two decades a variety of probes and inhibitors for (hemi)cellulose degrading enzymes have…

The IBL Education Office consists of:

The Biology programme offers 4 research-oriented specialisations corresponding with the research themes within the three institutes involved. You can choose a more practical-oriented specialisation if you would like to combine Biology with education, management business, or science communication.

The IBL-office welcomes you and will answer all your questions regarding general information, administrative issues, or redirections towards IBL subdivisions and people.

Decentralized plug and play systems for energy production are the future picture of our society. Artificial photosynthetic systems are used for this purpose.

Education in Environmental Biology

The Institute of Biology Leiden (IBL) is an internationally oriented institute for research and education in biology. We are part of the Faculty of Science at Leiden University.

The IBL PhD and Postdoc Association, also known as IPPA, seeks to create a platform for PhDs and Postdocs at the Institute of Biology Leiden to interact with one another. IPPA arranges social gatherings approximately four times each year, which include food and drinks, with the goal of integrating PhDs…

The Board of Examiners consists of scientific staff members of the IBL, Naturalis Biodiversity Center and CML, who teach in the biology programmes. They are appointed by the Board of the Faculty of Science and act independently from the research institutes. The responsibilities of the board include…

The Biology and Education specialisation consists of 120 European Credit Transfer System (EC) points and consists of a Biology component (60 EC) and an education component (60 EC).
