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…

Large carnivore population is globally declining as a result of the fragmentation of habitat, large prey depletion and retaliatory killing by pastoralists.

This liber amicorum is a tribute to Prof. dr. ir. Hans H. de Iongh, associate professsor at the Institute of Environmental Sciences (CML) of Leiden University and guest professor at the University of Antwerp, on the occasion of his retirement on 27 October 2016.

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.

Corona be damned, it's high time for the yearly LION Image award! Deadline in a week.

On 15 January, the winner of the famed LION Image Award will be announced. Submissions ranged from the famous 3d printed microboat to an eerily abstract graph depicting a Majorana fermion.

Finally, it's high time for the yearly LION Image award. Send us your most impressive, beautiful or insightful physics image, and win eternal fame on top of 100 euros, and a year long exhibition on the LION picture wall.

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

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

Reseachers of the Institute of Environmental Sciences Leiden (CML) have contributed to a debate in the Journal Nature over whether lions in Africa can only be saved with dollars and fences.

The 'Intelligent Lockdown' has lasted over a month now, which makes experimental physics research hard to do, if not downright impossible. Even so, work is continuing. Five Leiden physicists tell us about it.

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.

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.’

Biologist Laura Bertola argues that the traditional separation of lions into African and Asian subspecies is incorrect. She has discovered that Africa is actually home to two subspecies. Her PhD defense was on 18 March 2015.

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.

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…

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…

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.

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.

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.

Photographer Taco van der Eb accompanied Kenyan and Leiden researchers and students on a trip to Lake Nakuru National Park to record their conservation activities.

The annual LION Image award goes to the 30 micrometer long 3D printed microboat image that went viral earlier in October 2020, submitted by Rachel Doherty of the Daniela Kraft lab.

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’.

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…

Prof.dr. Rozenberg, emeritus professor in Theoretical Computer Science at the Leiden Institute of Advanced Computer Science (LIACS), received a royal decoration from the deputy mayor of Leiden on December 15th 2017. He has been appointed Knight in the Order of the Netherlands Lion.

During a symposium in honour of his 60th birthday, statistician Aad van der Vaart received the royal award of Knight in the Order of the Lion of the Netherlands. Colleagues talk about his significance for their field and how they got to know him. ‘The collaborations with Aad have been one of the great…

She stands out for the moderate tone she takes in discussions on Dutch talk shows. Without judgement you can have an open conversation, criminal lawyer Natacha Harlequin learned in her student days in Leiden. ‘What I personally think of the alleged act doesn’t matter so much.’

Leiden University investigates biodiversity not only in the Netherlands, but also abroad, with the goal of improving global nature conservation. We do so in collaboration with local universities. Education is also high on our agenda.

Can we make quantum devices from quantum surprises? And can we explore and build life from the nanoscale up?

LION offers a PhD program in which candidates carry out independent research on a specific topic, culminating in a PhD thesis.
