The Netherlands eScience Center has announced to fund a new Path-Finding Project led by Dr. Dorothea Samtleben from the Leiden Institute of Physics (LION). This project aims to make the processing of detection signals more efficient for the KM3NeT neutrino telescope, which is currently under construction…

What is the population size and social structure in time and space? What is the lion diet and food preference in time and space? What is the home range (MCP and Kernel) and movement in time and space? What are human – lion conflict and responses of lions to traditional herding in time and space? What…

Researchers from Leiden see hungry villagers in the north of Cameroon steal meat from the prey of lions. The researchers from Leiden University's Institute for Environmental Sciences (CML) reported on this kleptoparasitism in the online publication of the African Journal of Ecology in July.

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.

Lions in West and Central Africa form a unique group, only distantly related to lions in East and Southern Africa. Biologists at Leiden University confirm this in an article published in Scientific Reports.

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.’

A recent publication in Oryx, The International Journal of Conservation by Tumenta et al., 2013 (Leiden University) on human-lion conflict over livestock depredation in Waza National Park, Cameroon has demonstrated that the human-lion conflict remains an important factor in the depletion of lion pop…

Sander Blok has won the third edition of the annual LION Image Award. He created a colorful image of gold nanoparticles with a low-energy electron microscope.

We are happy to announce the 4th annual LION Image Award!

We are happy to announce the 3rd annual LION Image Award!

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.

In the theme of Big Cat Month, National Geographic interviewed Professor Hans de Iongh, guest researcher of the Institute of Environmental Sciences (CML) about lion conservation in Africa.

During the farewell reception on 29 August, the Faculty of Science will say goodbye to Dean Geert de Snoo. On 1 November 2019, he will continue his career as Director of the Netherlands Institute of Ecology (NIOO-KNAW). Colleagues talk about his significance for ecology, about his contribution as a…

Curiosity is the driving force behind the research of ecologist Michiel Veldhuis. The associate professor investigates ecosystems in relation to climate change in the savannahs of Africa. More and more, he is also looking at social factors such as the influence of population growth. The KNAW rewards…

The 2015 Dissertation Prize of the Global Neutrino Network has been awarded to Tri Astraatmadja, who was part of the Leiden/Nikhef ANTARES group during his PhD research. Astraatmadja receives the award for his thesis 'Starlight between the waves: In search of TeV photon emission from Gamma-Ray Bursts…

From 16 to 26 July, the Leiden Institute of Physics organizes its annual summer school, titled ‘Modern Physics at all Scales’.

Mazène Hochane and Xueying Fan have won the fourth annual LION Image Award. They created a detailed colour image of a human kidney in development.

In honour of 10 years of cooperation between Kenya Wildlife Service and Leiden University, a Leiden delegation visited Nairobi National Park. To cement the cooperation, a lion in the park was collared and named Karel, which in Dutch literally means ‘free man.’ It will be monitored through satellite…
