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.

'Today, conservation, regardless of its form, is and should be in everyone’s interest. With the escalating threats to ecosystems worldwide, conservation has become a necessity in response to ongoing processes of degradation, decay and loss. Traditionally, the word ‘conservation’ has been synonymous…

The project aims to conserve and consolidate the entrance gate to the Roman Desert Frontier Fort Qasr Bshir.

Exploring the intersection of environmental conservation, indigenous cultural expectations, and human-nonhuman relationships in the Eastern Himalayas. Developing inclusive approaches to ecological preservation through community-centered research.

When people and tigers use the same forest, their ability to cope and co-adapt to the influences of the other is much higher than currently understood. This is one of the conclusions drawn by Leiden BioSocial researcher Shekhar Kolipaka, who researched whether tigers can survive in human-dominated…

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…

During his visit on 12 April 2016, Dr. Jatna Supriatna was appointed as visiting scholar at the Faculty of Science of the Universiteit Leiden. Dr. Supriatna is a biologist, and is a senior lecturer at Universitas Indonesia’s Department of Biology. His appointment was made in the context of increasing…

This thesis focuses on the social dimensions of crane and wetland conservation in rural landscapes in Kenya, Uganda and Zimbabwe.

The Hortus botanicus Leiden connects science with the public. Through our research, we explore how people experience and appreciate nature while addressing key societal challenges.

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…

The multiple connections between emblematics and Natural History in the broader perspective of their underlying artistic, literary, political and religious ideologies.

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…

How can innovative collective action methods restore biodiversity in socio-ecological lifescapes across livestock-dominated regions?

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.

The Historia Naturalis Brasiliae Reconsidered

Evolution acts via mutations in amino acid sequences. Substitution of essential amino acids leads to a nonfunctional protein. l.

This dissertation is a study of the view of the Neoplatonist Proclus (Athens, 411-485) on to what extent and how the changing and unreliable world of sense perception can itself be an object of scientific knowledge.

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.…

How many species of plants, animals and fungi live in Leiden? Leiden is observing and recording how many unique species there are in Leiden, to put the state of urban nature on the map. Residents (and scientists) will record every spider, snail, mushroom or dandelion they come across during ‘Expeditie…

Research in the Natural Computing and Optimization cluster covers theoretical foundations, the development of new algorithms, and interdisciplinary applications of natural computing methods.

It is well-known that humans have significantly transformed ecosystems since their adoption of agriculture. However, in a deeper past, prehistoric hunter-gatherers may already have altered and modified their niche in ways that had major impacts on ecosystems.

Natural Computing investigates algorithms and phenonema based on nature to create better and new computer science innovations.

This dissertation explores Aristotle’s use of teleology as a principle of explanation, especially as it is used in the natural treatises.

A neural network mimics how our brain works. Evolutionary algorithms use the principle of natural selection to solve complex problems. This kind of 'natural computing' is being used to improve the diagnosis of Parkinson's disease or the production of steel.

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.

The fourth volume of Ex Novo has the pleasure to host Heleen van Londen, Marjo J. Schlaman, and Andrea Travaglia as guest editors of the special issue titled The Natural and The Cultural. Integrating Approaches in Landscape Heritage Management. This timely collection of peer-reviewed papers and short…

We depend on nature for so many things: from clean water, wood and food to carbon absorption, water purification and coastal protection, as well as for relaxation, inspiration and identity. Nevertheless, our modern world putting increasing pressure on these ecosystem services. Leiden researchers investigate…

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.

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.

In his dissertation Michiel Hooykaas outlines the results of six empirical research projects focused at biodiversity awareness in the Netherlands, specifically people’s knowledge about animals.

LUGO's Autumn Event 'Requiem for Nature' took place late November and was a great success!
