How can people and lions sustainably coexist?

Master

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

Every year, the Leiden Institute of Physics (LION) organises the Science Day. The goal is to highlight the newest research at LION, to socialise, and to welcome first year master students and new PhD's and Postdocs to our institute.

The annual Leiden Institute of Physics (LION) summer school offers outstanding bachelor students the opportunity to discover the research frontiers of modern physics. The programme includes seminars by renowned physicists on variety of topics, visits to research laboratories, and a range of social a…

Despite their ecological, cultural, and economic importance, lion (Panthera leo) populations in Kenya are declining rapidly due to retaliatory killings following livestock depredation, depletion of wild prey, habitat loss driven by human activities, climate change, and disease.

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.

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.

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.

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.

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.

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.’

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…

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.

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…

Self-censorship violates principles of a free society but few people want to take the role of the martyr.

Human measures to protect lions have an impact on the genetic health of populations. Leiden and Kenyan scientists discovered this by analysing the DNA of 171 Kenyan lions. ‘By fencing reserves, for example, the chance of inbreeding increases.’ With the knowledge and tools from the research, management…

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.

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’.

Agriculture is among the most vulnerable sectors to climate change and poorer countries face the most severe difficulties. Coffee farmers in Central America, for instance, are facing multiple and mutually reinforcing crises, including price shocks, outbreaks of pests and diseases, migration, and farm…

This thesis describes how different colours of light affect various aspects of the growth and development of Arabidopsis and tomato plants⁠.

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.’

Brexit has been a kind of shock therapy for the EU and has eventually led to more appreciation for European cooperation. That is what Professor Luuk van Middelaar claimed on 30 November at the conference ‘Brexit and the future of the European Union’ which marked the 60th anniversary of the Europa Institute…
