Freshwater and brackish water ecosystems are arguably the most vulnerable ecosystems on earth, due to concentrated human developments in and around them. The Pontocaspian (PC) region located at the border of Europe and Asia contains a variety of brackish water ecosystems and unique inhabitants, known…

This project aims to develop advanced data analysis methods for monitoring and increasing our understanding on biodiversity dynamics in nature reserves such as the Oostvaardersplassen.

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…

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…

‘Qasr Bshir is magnificent even in decline. It sits majestically in the landscape, master of all it surveys. On approaching the site, however, it is clear that the structure is damaged’, states the latest issue of the journal Current World Archaeology.

Plant diversity is essential for us and our planet as it sustains the stability of our ecosystems, provides vital materials and food to us and supports many ecosystem services.

Large carnivores and humans, along with their livestock, have co-existed for thousands of years. However, human population growth and an increase in economic activities are modifying the landscape for large carnivores and their prey.

Hortus botanicus Leiden is the first Dutch garden to receive an accreditation from Botanic Gardens International (BGCI). The Conservation Practitioner Accreditation is a certificate that recognizes the policy, knowledge & expertise and education with regard to plant conservation at an international…

In 2005, the LEAD Programme organised and coordinated the International Exhibition on ‘Jamu: Medicinal Plants for Health and Conservation in Indonesia’ in collaboration with Universitas Padjadjaran (UNPAD) in Bandung, Indonesia, the Mediterranean Agronomic Institute of Chania (MAICH) in Chania, Crete,…

How can we understand the material instability of photographic (mixed media) artworks (1960s - present) from an integrated approach of Art History, Conservation Science and Chemistry in order to preserve these works for the future?

This research programme aims to increase the scientific understanding of how current and emerging anthropogenic threats affect biodiversity and ecosystem services to facilitate strategic management of natural resources. To this end, we address urgent challenges in relation to the mechanisms involved…

‘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.

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 project aims to explore Eurasian elk's role in the ecosystems of the past and its relationship with humans through analysis of its distribution and habitat in the Netherlands.

Farmers who commit to environmentally friendly working methods also actively practise nature conservation in their farming - particularly when this is not financed by the government. These are the findings of research carried out by Anne Marike Lokhorst, who will receive her PhD on 17 September based…

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…

The plant hormone auxin plays a central role in the growth and development of plants. Auxin acts in a concentration dependent manner and polar cell-to-cell transport of this hormone determines its distribution in the tissues of plants. This polar auxin transport is mediated by several families of auxin…

Bacteria often experience external challenges, such as changes in environmental conditions or attacks by bacteriophages.

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