One of the effects of climate change is the phenomenon of desertification, a process that occurs in semi-arid and arid areas and causes land degradation as well as vegetation loss. Due to the lack of resources, vegetation self-organizes to sustain itself by forming large-scale spatial patterns.

Vast, often populated, areas in dryland ecosystems face the dangers of desertification.

In this PhD study, I aim to deepen our understanding of the influence of major mycorrhizal types, namely arbuscular mycorrhizae (AM) and ectomycorrhizae (EM), on the global soil carbon cycle and their potential distribution changes under future environmental shifts.

A new study in Nature Plants has explored the most important organising principles that control vegetation behaviour. The insights from this study can be used to improve predictions on climate change. Leiden scientists Peter van Bodegom and Nadia Soudzilovskaia participated in the study.

Which plant species grow where - and why? In a new study in Nature Ecology & Evolution, an international research team presents the world's first global vegetation database which contains over 1.1 million complete lists of plant species for all terrestrial ecosystems.

As fruit and vegetables ripen, ethylene gas is released. Ethylene also influences the speed at which they ripen. Chemist Tom van Dijkman studied how small and inexpensive sensors can be made that measure ethylene concentrations during transportation. PhD defence 12 May 2016.

This thesis describes the functional analysis of the Arabidopsis AHL15 gene.

What are key regulators of plant ageing that can reverse ageing in plants (rejuvenation), and how can we use this knowledge to improve crop plants?

What plants grow along ditches in the Leiden region? What does this say about vegetation quality? Could it be better? Naturalis and Leiden University's Center for Environmental Sciences are looking for your help to answer these questions.

Leiden has one of the most petrified inner-cities of The Netherlands. This is not beneficial for the biodiversity crisis and Leiden University, with a significant number of buildings within the Singels, should be more proactive on this matter. Currently, LUGO is taking steps with internal departments…

Streptomyces are multicellular, Gram-positive bacteria in the phylum of actinobacteria which produce a high amount of bioactive natural products of which the expression is tightly coordinated with the life cycle.

The Hague is alive with nature – you just have to look

In November we went to a real, biodynamic farm (Kwekerij Eko Logisch) and listened to David, a farmer who believes you can limit harm to the environment while still growing heaps of vegetables, fruits, and herbs. On the two-hour visit, we were shown around the farm and even encountered some animals.

This project studies the roles of prehistoric foragers in past ecosystems to establish the character of past “natural” landscapes and enhance the management of current ones.

This study aims to provide a long time perspective of human landscape manipulation. Studying the roles of prehistoric foragers in past ecosystems is of great importance to establish the character of past 'natural' landscapes and to enhance the management of current ones.

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…

The Heritage Quest project is a citizen science project in which volunteers participate in archaeological research.

This part of the research programme is carried out by Prof. Dr. René Cappers. It focusses on the continuities and changes in the use of plants at Late Neolithic Tell Sabi Abyad, as well as on their implications as proxy evidence for the climate change c. 6200 BC. Parallel to the design of the other…

Leiden University and the Municipality of Leiden worked together on the development of the Schilperoort Park. This new public space is situated in the north-eastern part of the Leiden Bio Science Park. The park ambience is extended into the adjacent residential area, where former medical laboratories…

We aim to provide new insights relating to the spectacular multi-cellular life cycle of streptomycetes and other actinobacteria.

Ethiopian wolves are endangered diurnal Afroalpine rodent hunters. I investigated the interaction between wolves, rodents and human land use in Borena Sayint National Park (BSNP), Abune Yosef and Aboi Gara in Ethiopia.

In light of climate change, it is crucial to determine whether plant species can adapt to future climates to avoid extinction. Plants adapt to various conditions by altering their functional traits, such as leaf size or photosynthetic rate. Some traits appear linked and vary together between species,…

Heritage Quest is a citizen science project in which volunteers help archaeologists in the quest for undiscovered archaeological heritage.

What motivated past human societies to repeatedly invest labour, generation after generation, in constructing, maintaining, and enhancing monumental structures in an environment prone to frequent and unpredictable natural disasters? Moreover, how did societal resilience and periods of heightened or…

Human impact and plant subsistence in Dutch wetlands during the Late Mesolithic and Early and Middle Neolithic (5500-3400 cal BC)

To what extent does human intervention influence the world’s biodiversity? And can we predict how biodiversity and ecosystems will change in the coming years? Inaugural lecture by Peter van Bodegom, Professor of Conservation Biology, on 8 May.

A palaeogeographical reconstruction of Bronze Age West-Frisia (2000-800 BC)

This project aims to explore the environmental impact of early Roman expansion (4th/3rd century BC) through a program of dating and ecological sampling of traces of field systems (centuriations).

This thesis presents the systematics, epidermal defense, and bioprospecting of wild orchids.

How does climate change affect the migration routes of birds? Mainly negatively, according to a new study from Yali Si from the CML. ‘It changes the timing of natural events differently in each region,’ she explains. ‘This can lead to a growing mismatch between the availability of food and the supposed…
