Two bacterial species team up inside the plant root system to rescue their host from fungal infection. This was discovered by a team of microbiologists and bioinformaticians from the Netherlands Institute of Ecology, Wageningen University, and the Institute of Biology Leiden. They also identified the…

Generations of Leiden students and academics have done archaeological research into the early medieval history of Oegstgeest. This makes this old settlement one of the best-documented sites from that era. In a new book, Leiden researchers take stock.

Plants that are pollinated by fewer species of animal may be less vulnerable to change than was thought. This is what Saskia Klumpers discovered in the Rocky Mountains in Colorado. She will be awarded a PhD on 15 December.

A special relationship between plants and fungi, which plays an important role in carbon storage in soil, has the potential to slow down climate change. However, the amount of carbon stored in soil is decreasing as a result of human activity. This is what researchers say in a publication in Nature Communications.…

The Leiden Archaeology social media team presents its first documentary on one of our faculty's research projects. A team led by Bleda Düring, Victor Klinkenberg, and Maria Hadjigavriel explores the Cypriot Chalcolithic period in Palloures, Cyprus.

Research on Asian plants is his life's work. Now a crown is added to that: a plant from the coffee family bearing his name. Paul Kessler is LUF professor of botanical gardens and botany of South East Asia and Scientific Director of the Hortus botanicus. 'Completely unexpectedly, you get to see the results…

Environmental scientists in Leiden have found that the so-called leaf economics spectrum for plants can not only be applied to terrestrial ecosystems, such as forests and grasslands, but also to wetlands. Furthermore, they showed that wetland plants generally have a fast-return strategy, meaning they…

The main question I want to answer is about the mutual influence between the cultural and settlements changes that occurred between the Bronze and the Early Iron Age in Margiana and the management of water resources.

‘What I find most alluring about soil life is that you can steer it,’ researcher Martijn Bezemer of the Institute Biology Leiden (IBL) reveals. ‘You can ask: What do you want? And then I can transform the soil into something you need. At least, that is what we thought.’

Soil that is too wet, or too dry. Or with a lot or few nutrients. Due to climate change, the differences are becoming bigger, and plants must increasingly be able to adapt to survive. How do you make plants more stress-resistant? For this purpose, researchers from Leiden, along with other universities,…

Leiden physicists are helping Wageningen plant researchers to study unpredictable plant embryos. For this, they are using a novel two-photon fluorescence microscope, aided by a 30 thousand euro ZonMW grant.

Leiden biologists have shown that a gene present in plants, animals and yeasts does play an important role in plants, although for years the gene was considered unimportant. It turns out the gene plays a crucial role in the development of vascular tissue in plants. Publication in Nature Plants on 11…

This handbook provides a resource for those already familiar with some kinds of micro-particles who wish to learn more about others, or for those just starting out in the study of microremains who wish to have a broad understanding about microscopic archaeology.

The archaeological heritage of South America is facing increasing threats due to the expansion of agricultural activities, infrastructure expansion, illegal wood harvesting, and the current fire emergency plaguing the Amazon and other biomes of the continent.

What is the role of local Caribbean individuals and communities in creating and perpetuating archaeological heritage? How has archaeological knowledge been integrated into education plans in different countries?

PhD candidate Jianhong Zhou aimed to better understand whether and how plant species adapt to environmental changes. She developed two databases that she used to analyze how easily or difficultly plants adapt to changing conditions. Zhou defended her PhD thesis on 4 September.

Apps that can precisely identify shards, coins or heel bones: archaeology has embraced artificial intelligence. Alex Brandsen is working on a search engine that scans vast quantities of text from an archaeological viewpoint.

Generally the data from remote sensing surveys - the scanning of the earth by satellite or aircraft in order to obtain information about it - is screened manually in archaeology. However, constant monitoring of the earth's surface causes a huge influx of data of high complexity and high quality. To…

Professor of Archaeometry Patrick Degryse analyses archaeological finds using techniques from chemistry, physics and biology. He will give his inaugural lecture on 19 February. He reflects on three interesting propositions from his lecture.

At the Faculty of Archaeology, three new professors are appointed with effect from February 1, 2018. They are Ann Brysbaert, Marie Soressi, and Joanita Vroom. How do they react to their appointments, and what will be their foci in the following years?

This thesis focuses on the design and synthesis of activity-based probes and inhibitors targeting enzymes involved in the degradation of specific plant glycans.

This research investigates the changing landscape and land use in two case studies of the coastal villages of St. Kitts and the Kalinago Territory of Dominica. By integrating human and ecological aspects of agrarian landscapes, this research analyzes how land degradation or land change impacts cultural…

The research article ‘Anatomy of a notch. An in-depth experimental investigation and interpretation of combat traces on Bronze Age swords’ is one of the most downloaded articles on the Journal of Archaeological Science website. This journal is one of the best for impact factor in the field. The article,…

The 10th Experimental Archaeology Conference of EXARC took place in Leiden, Netherlands, over three days; 20th to the 22nd April 2017, in Leiden University’s Faculty of Archaeology. A conference report was published on the website of EXARC.

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

What does the excavated material tell us about the continuation and/or change of urban life during the transitional phrases from Antiquity to the Middle Ages on Crete and in the eastern Mediterranean more generally?

Water Management, Agricultural Practices, and Social Complexity in Southern Turkmenistan during the Bronze Age

Trinidad and Tobago, a twin-island nation, has over 300 identified archaeological sites that testify to its diverse history, covering pre-colonial, colonial, and post-colonial periods. Many of these sites were discovered by archaeologists in the 20th century and have not been regularly visited and assessed.…

Une étude archéo-anthropologique de la céramique des sociétés caribéennes multiculturelles de la période précoloniale à nos jours

This publication brings together two contributions born of different intentions but which are both dedicated to Hellenistic pottery of the Alexandria region.

Which plants in the Mediterranean garden were already known to the ancient Greeks and Romans, and how were they utilized?

The MicroSOS project is designed to bring together academic and industrial partners with different expertises to address challenges that agriculture is facing due to climate change and invests in the development of microbiome-based solutions towards more sustainable agricultural practices.
