LIAS researchers working in the field of linguistics hold dual appointments in LIAS and the Leiden University Centre for Linguistics (LUCL).

Like ants, termites and bees, some bacteria work together as a multicellular group. There is a strict division of labour in such colonies, to make the group more resilient to the outside world. Now researchers have found that some parts of the bacterial colony can take ‘for the greater good’ to a whole…

For nine years he worked on the three-volume standard work Plant Galls of Europe. It yielded 2300 pages about 10,000 species of European galls, abnormal outgrowths in plants caused by parasites. Hans Roskam from the Institute of Biology Leiden: ‘The abundance of galls says something about the natural…

In this project, we will study the genetic and environmental drivers of woodiness and stem lignification at the level of plant‐to‐gene‐to‐molecule.

Man-made sounds in and around the oceans stress marine life and have an impact on marine species and ecosystems by changing the underwater acoustic climate. Hans Slabbekoorn from the Institute of Biology Leiden pleads for technical solutions to mitigate problems of noise pollution. Science review paper…

If male budgerigars can successfully open a puzzle box with food, they become more attractive to females. Biologist Carel ten Cate and Chinese colleagues publish experimental evidence for this in a paper in Science on 11 January .

Ben Wielstra studies hybrid zones, regions in which distinct populations of organisms meet, mate and produce genetically admixed offspring. In the journal Current Biology, he introduces hybrid zones in an accessible way.

Streptomyces are filamentous bacteria that produce more than two-thirds of known antibiotics.

We will study how inoculation of former arable land with soil (including the microbiome, soil fauna and seeds/rhizomes of ground flora) from old forests along with planting targeted tree species mixtures will improve productivity and more rapidly restore forest-adapted communities and ulttimately result…

This thesis investigates how galaxies form and what diversifies the evolutionary histories of galaxies.

Daniel Rozen (45), at the IBL since September 2012, uses bacteria in laboratory tests on experimental evolution to study the ecology and genetics of adaptation. His research has applied importance, as it reveals how bacteria may be induced to produce new antibiotics. Last January, Rozen received the…

During the pre-PhD phase the Dual PhD Centre collaborates with the candidate to find a suitable doctoral supervisor (Dutch: promotor) and graduate school. The doctoral supervisor has a critical role in the dissertation research process. Under his/her supervision, the candidate develops a dissertation…

‘I did not expect to receive the grant, but it will make an amazing research possible,’ Michelle Spierings says. The researcher of the Institute of Biology Leiden (IBL) got awarded a Veni-grant of the Dutch Research Council (NWO).

Within the same species of butterfly many different wing patterns can occur. How is this possible? According to researchers Ben Wielstra and Emma Berdan, of the Institute of Biology Leiden (IBL), the answer lies within supergenes. A supergene is a part of a chromosome that contains many strongly linked…

The thesis addresses the long-term dynamical evolution of hierarchical multiple systems.

The solar system was formed approximately 4.56 billion years ago. Despite the numerous theories that have been developed over the years, the formation and evolution of the solar system still remain unclear.

This thesis addresses the chemical processes that determine the compositions of giant planet atmospheres.

The Service Centre International Staff provides advice and different services to all international employees and guest researchers pursuing their academic careers in Leiden.

Ben Wielstra studies balanced lethal systems, in which half of the offspring die before birth. In the journal Current Biology, he explains in an accessible way how such a disadvantage can originate in nature.

Ben Wielstra and his team have received a ENW-M-1 grant. This grant of 354.000 euros is awarded by NWO, and will enable the researchers of the Institute of Biology Leiden and Naturalis to continue their evolutionary newt research.

In honor of Nobel laureate ethologist Niko Tinbergen, the Leiden University in collaboration with the NRC Handelsblad, NWO, and Naturalis Museum Boerhaave organizes the annual Tinbergen Lecture.

Lecture

On 22 January, Annemarie Madani-Abbing will defend her dissertation 'Art therapy and anxiety' regarding her research into the effectiveness of anthroposophic art therapy in treating anxiety in women. We asked her about her research and what it was like to combine a job outside academia with studying…

On Thursday 11 November, Women in International Security Netherlands (WIIS-NL) held its inaugural webinar event on 11 November with four speakers in conjunction with the International Centre for Terrorism (ICCT) and the Chair UN Studies in Peace and Justice at Leiden University.

The Dutch Research Council (NWO) awarded behavioural biologist Hans Slabbekoorn (Institute of Biology Leiden) a grant of 750,000 euros to study fish and sounds around wind farms in the North Sea.

We perform multidisciplinary research at molecular, cellular, and organismal levels of animal biology to increase fundamental understanding of health and disease.

The research aims to explore the evolutionary adaptability of enzymes and the impact of temperature on protein evolution pathways, using M. tuberculosis β-lactamase BlaC as the object of study. Enzymes inherently embody a delicate balance between activity and stability, and the acquisition of new enzymatic…

The Leiden University doctoral / PhD programme takes around four years of study and consists of independent and original research under the supervision of a professor.

This thesis describes the design, synthesis, and immunological evaluation of varying (neo)antigenic peptide conjugates containing either a TLR2 or a TLR7 agonist.

The book Global Gold Production Touching Ground: Expansion, Informalization, and Technological Innovation is edited by Boris Verbrugge and Sara Geenen. In recent decades, gold mining has moved into increasingly remote corners of the globe. Aside from the expansion of industrial gold mining, many countries…

Circumstellar discs are the reservoirs of gas and dust that surround young stars and have the potential to become planetary systems.

Diverse types of exoplanets such as gas giants on close-in orbits (hot Jupiters) and young massive giants on wide orbits (super Jupiters), with no analogs in the Solar System, pose challenges but also opportunities to our understanding of planet formation and evolution.

For a long time, bird song was considered as a typical male trait. But over the last twenty years, research has shown that a lot of female songbirds sing as well. Female scientists turned out to be the key factor in these findings, amongst others from the Institute of Biology Leiden.

Reputation literature has provided crucial insights about the evolution of the US regulatory state. Daniel Carpenter’s influential account painstakingly demonstrates the relevance of reputation to bureaucratic ‘power’ and to early institutional state-building in the US context. We argue that adopting…

Master's student Thalia Luden receives an NWO grant for her research proposal about a gene that brings flowering plants back into a growth phase. Companies in floriculture and vegetable seed breeding also contribute to the research.

That a parrot can copycat sounds is nothing new. But vocal learning is not common in animals. Researcher Carel ten Cate of the Institute of Biology Leiden (IBL) of Leiden University has now discovered a duck species that can imitate sounds. ‘It started with an obscure reference about an Australian musk…

Pigeons, zebra finches and parakeets. Carel ten Cate studied bird sounds. But not just that. Together with linguists from Leiden, he investigated parallels between birdsong and language. On 9 June, his farewell symposium was held to mark the end of his broad career. Well, the end? Carel ten Cate has…

Fishes rely heavily on sound to find their way during migration or dispersal. Many species are affected by noise pollution. Hans Slabbekoorn from the Institute of Biology Leiden received a HORIZON2020 grant of 500,000 euros to study the impact of sound conditions on movement decisions of fishes.
