CML researchers Nadia Soudzilovskaia, Rene Kleijn, Stefano Cucurachi, and Kevin Groen are teaching about the links between city sustainability and biodiversity, within the “Material city” course of the Bachelor Urban Studies curriculum. An online pre-view of an excursion on city biodiversity given by…

The Dutch organisation for scientific research NWO has announced that it will award an ENW-Klein grant to Marcellus Ubbink (LIC) for his research into the role of temperature in the evolution of enzymes. Sixteen grants have been awarded in total.

The origin and evolution of galaxies are closely linked to many different physical phenomena.

Nederland ligt in de periferie van het verhaal van menswording. De evolutie van onze familie vindt lang exclusief in Afrika plaats. En, als Europa eenmaal bewoond wordt door mensachtigen, ligt het zwaartepunt ten zuiden van onze streken. Toch heeft ons land een aantal interessante vindplaatsen en vondsten…

How do molecules originate and evolve in space? And how does that ultimately determine the chemical composition of planets and their atmospheres? The Dutch Astrochemistry Network (DANIII) receives 1.6 million euros from NWO to find out. A large group of Leiden astronomers and chemists is contributing:…

Dutch children’s picture books are full of animals, but mainly mammals are portrayed. Especially pets and exotic animals are popular. A large part of the Dutch fauna is less visible, but biologist Michiel Hooykaas of Leiden University sees plenty of opportunities for a more biodiverse book world.

Population growth, economic expansion and the associated land use caused an increase in the number of bird species facing extinction and a reduction in carbon storage worldwide. These are the findings of an international team of scientists, also from the Leiden University Institute of Environmental…

1: What is the relative importance of alfa and beta biodiversity in polar ecosystems, and how does intraspecific variation influence this? 2: How can we use remote sensing to determine functional biodiversity (within communities) in polar ecosystems? 3: Temporal and spatial scales of functional biodiversity:…

We developed the bitterling as a unique, well-studied model organism in the area of the evolutionary ecology of brood parasitism. The bitterling-mussel relationship, interspecific mussel host preference, and mussel gill structure are studied in detail, to help understand the developmental adaptation…

The Altai region has yielded a cluster of Middle and Upper Paleolithic stratified sites that have been recently excavated using a multidisciplinary approach.

Galaxies in the Universe are distributed along the intricate framework of the Cosmic Web. Groups and clusters of galaxies comprise the densest regions in this network, and therefore, are excellent cosmic laboratories to study different aspects of galaxy evolution in extreme environments.

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…

In our lives we often have little attention or appreciation for plants, let alone the ones we commonly call weeds. This inattention for plants has been described as plant blindness. The Stoepplantjes project aspires to decrease plant blindness by changing the image of weeds and using citizen science.…

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.

The application of nanomaterials in industrial processes and consumer products provides many societal benefits, but can also lead to the release of nanomaterials into the environment. The work in this dissertation aims to provide insights into the potential environmental impacts that may follow from…

State Secretary Sander Dekker of Education, Culture and Science received the national research agenda Nature4Life on 31 January. This research agenda, in which Leiden University is involved, focuses on research on biodiversity, ecology and evolution.

What invertebrates live in the fields and edges? Do the populations change with landscape complexity?

What invertebrates are available to feed nestlings in an agricultural landscape of varied complexity?

What we buy and consume in Europe often has an impact on biodiversity somewhere else in the world. With a Horizon Europe Funding of 600.000 euros, assistant professor Laura Scherer and her team will develop models to look at the impact of global trade in non-food biomass. ‘After developing the models,…

Galaxies are environments where gas coalesces, cools, and is converted into stars. However, it remains unclear the exact mechanisms through which galaxies acquire, redistribute and lose their gas.

In this project we study the properties of statistical- and rule-learning mechanisms in relation to the acquisition and evolution of language. We ask to what extent these mechanisms are unique to humans - or to human language - by comparing the acquisition of vocal structure in two species: humans (infants)…

This thesis pioneers diatom molecular identification and quantification through genome-scale methods, with four key aims: (i) reviewing DNA/RNA sequencing methods in aquatic biomonitoring to highlight their strengths and limitations;

Biodiversity enables ecosystems to thrive through the synergy of functional differences among organisms. While human well-being strongly depends on biodiversity-driven ecosystem services, human actions are also at the root of current unprecedented biodiversity declines.

The transition from single cells to multicellular organisms was a key step in evolution. Researchers from Leiden and Amsterdam developed a mathematical model that explains how this transition may have come about. They suspect cooperating cells may correct each other’s mistakes. Publication in eLife…

Venomous animals serve as models for a variety of mimicry types. Michael Richardson (IBL) and his international colleagues find that a group of fishes (called fangblennies) evolved venom after the origin of their venom-delivering fangs.

Radio jets are important to the evoultion of galaxies. However, it is still not fully understood how a radio jet can be triggered.
