How does invasive hybridization affect threatened native species?

‘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.

The ‘Stans Prize 2010’ has been awarded to Leontien Cenin and Lisanne Daniëlle Korpelshoek for their research on impacts of landuse on three migrant harriers in northern Cameroon.

China’s booming aquaculture industry is increasingly dependent on fishmeal made from wild-caught fish, a practice that depletes wild fish stocks. A new study conducted by institutions including Leiden University and Stanford offers a more sustainable path. The study appeared in the journal Science on…

Short description about 20th anniversary of CEDC, the fieldstation in Cameroon, and 20 years of cooperation between Leiden University with the University of Dschang in Cameroon.

The rare Ethiopian wolf is increasingly coming into contact with local cattle farmers. PhD candidate Girma Eshete explored ways of saving this elegant animal from being wiped out. Phd-defense on 5 September.

The number of lions in Kenya is decreasing alarmingly, due partly to the encroaching cities and the development of the countryside. Together with local scientists and inhabitants, Leiden biologists are studying how this decline can be halted. ‘Lions are cleverer than we thought.’

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.

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.…

What are the main factors associated with the stranding of the two seal species? What are the factors influencing the prevalence of disease in the two species? Which human-related factors influence the populations of the two seal species?

PNEC-pro is a user-friendly screening tool for professionals dealing with the assessment of surface water quality. The tool calculates local, watertype specific no-effect concentrations (PNEC) of copper, lead, nickel, and zinc based on biotic ligand models (BLMs).

PhD candidates carry out a programme of independent research and additional (limited) course work, culminating in production of a PhD thesis in typically 4 years.

During embryonic growth, cells proliferate, differentiate, and collectively migrate to form different tissues at the right position and time in the body.

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.

Gayathri Jaikamur has been awarded by the Dopper Foundation in the Change Make Challenge. She is a student of Masters Biology (Specialisation: Evolution, Conservation and Biodiversity) from India - working under the supervision of CML-researcher Dr. Thijs Bosker (and co-supervision of Dr. Nadja Brun).…

Together with colleagues and students, Professor of conservation biology Geert de Snoo studies the decline of the lion population in a national park close to Kenia's capital city, Nairobi. He discusses how they try to protect the lions on radio Sleutelstad FM.

Does knowledge of environmental performance change farmer's behaviour?

Brings you the weirdest, funniest, most memorable biology of the moment!

The IBL represents the core of modern biological research at Leiden and we interact closely with the other life science Partner Institutes in the faculty:

How can we quantify the density of species within a community through environmental DNA concentrations?

Prof Hans de Iongh of the Conservation Biology department of the Institute of Environmental Sciences Leiden contributed from 30 January until 2 February to a workshop on Dugong-Seagrass interactions in Jakarta

Does the presence of Ring-necked parakeets negatively influence feeding and feeding behaviour of native bird species on artificial bird feeders and if so, what are possible solutions?

Nature is a never-ending source of inspiration for the researchers at the Institute of Biology Leiden (IBL). Based on a better fundamental understanding of nature, they are able to seek solutions in the area of health and biodiversity. The theme of IBL is ‘Harnessing biodiversity for health.’

From the 11th of May Ewa Snaar-Jagalska has been appointed Professor in the field of cellular tumor biology within the Faculty of Science at the Institute of Biology Leiden. Her research focuses on the cellular tumor biology and human cancer modeling in zebrafish

The master’s specialisation Biology and Education at Leiden University prepares students to teach the subject of biology to secondary school students. The programme comprises a one-year Biology component, followed by an education component in the second year.

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.

Biology is the study of life. Are you interested in understanding life, from the molecular level to entire ecosystems? Do you want to use your understanding and knowledge of biology to benefit the health of both humans and the environment? If so, Biology is the right study programme for you.

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 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.

Do Ethiopian wolves change their diet and foraging strategy in the landscape under different land uses? How land use affect Afro-alpine rodent Communities? How important are Afro-alpine natural resources utilisation for local livelihoods? What is the human perception of conflict in the Afro-alpine a…

Projects within the theme ‘Computational Biology’ aim to employ mathematical or computational dynamical modelling approaches to discover novel concepts that are important for drug development.

Chemical biology research at the Leiden Institute of Chemistry is aimed at understanding biological processes at the molecular level to strengthen the knowledge base of human health and disease. The approach to achieve this goal is a fundamental chemical one; with the aid of chemical probes biological…

The Netherlands is not particularly rich in ‘wild nature’. Comparatively, what we have is a lot of intensively used agricultural land. This means that from nature’s perspective there much to be gained by combining the ‘nature’ and ‘agriculture’ functions. Not an easy task in such a densely populated…

What is the population size/structure and distribution of tiger and leopard inside the Bardia National Park (BNP) compared with the population outside? What is the movement and home range and conflict pattern in time and space of tigers and leopards inside the BNP compared with outside? What constitutes…
