Proactive zebrafish appear to have a much stronger wake-sleep rhythm than reactive fish. In the most reactive fish, rhythmicity appears to be lacking completely. This is shown with research by Leiden biologists, published in December 2018 in the journal BMC Biology.

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.

Herman Spaink knows of many substances that may help combat tuberculosis. Lab space to study them safely is very limited in Leiden. A brand-new lab at Universitas Gadjah Mada in Indonesia will soon provide a solution. About time, says Spaink, ‘The disease is on the rise and is becoming less sensitive…

Avian Cognition describes the full range of avian cognitive abilities, the mechanisms behind such abilities and how they relate to the ecology of the species. Synthesising the latest research in avian cognition, a range of experts in the field provide first-hand insights into experimental procedures,…

Biologists today have to be able to work with big data. Data analysis skills should be taught from the start of the degree programme, or - even better - in secondary school. This is the message of Vera van Noort, new Professor of Computational Biology. Inaugural lecture 22 January.

Looking for ways to travel more sustainably once you've reached your destination? Here, we offer some ideas and helpful links to guide you in becoming a more responsible tourist. Ecotourism, defined as "responsible travel to natural areas that conserves the environment, sustains the well-being of…

Being a better neighbour to the nature around you

Humans and songbirds learn their vocalizations early in life by exposure to the vocalizations of adult conspecifics. Often, better learning outcomes are achieved with live, social, tutors than with audio-only exposure to vocalizations.

Can the venom of snakes, scorpions and other animals be sources of new antibiotics?

Five talks will be given during the Leiden Science Family Day: two children's lectures and three lectures for adults. Will you be there ?

Prof. Elizabeth de Lange is concerned with the allocation of resources for the conduct of science towards the goal of best serving the public interest. Also, while she underscores that there is still the need for using animals in drug research, she is concerned about this use, and advocates the use…

The thesis is about the study of shell evolution of the Hydrocenidae of the genus Georissa. This thesis started with a general overview on the evolutionary process of animals due to ecological changes.

In this thesis, I investigated the neurogenetic properties of Neotropical bat species. Bats represent the second largest mammalian order (Chiroptera) in the world, with Neotropical bats constituting about 13% of the total number of bat species.

S.S. Kolipaka’s thesis questions and investigates the survival prospects of reintroduced tigers and their offspring’s in the human dominated landscape of Panna tiger reserve in India.

New drugs for use as tuberculosis (TB) treatment are needed due to the constrains of classical antibiotics against TB and the rise of antibiotic-resistant strains, making TB a harder and harder disease to treat.

This PhD subproject concentrates on 16th-century ichthyology and takes Gessner’s Historia piscium (1558) (further HP) as its point of departure and focus.

This project, under the supervision of Prof. Dr. Hans van der Plicht, comprises several studies aimed at the use of isotopes occurring naturally in organic material as tracers for both the climate change and its cultural impact at about 6200 BC. The research will be carried out by the co-applicant at…

Members of the collective explore what it means to be ‘human’, in the past and present, from a range of different perspectives and inter-disciplinary approaches.

What categories exist in the languages of pastoralists? Do these semantic concepts reflect universal or languagespecific tendencies? What (environment? culture?) governs the similarities (or the differences) attested crosslinguistically in cattle colour systems?

Great apes and the right to health

This thesis focuses on enhancing predictions of central nervous system drug exposure using the LeiCNS-PK3.0, a physiologically based pharmacokinetic model.

The main aim of Eva's research is to create a frame of reference in which these animals as symbols must be understood, be they depicted on pottery, as amulets, as floor plans or in any other way. This frame of reference can then be used to interpret the various animal images encountered by Caribbean…

In this thesis, we have studied the potential of the zebrafish larval model in studying the ECS, as a complementary model to the existing rodent models.

Tuberculosis bacteria and other intracellular pathogens use cells of our immune system as Trojan horses to spread into tissues. Annemarie Meijer, professor of immunobiology, explains how research into innate defence mechanisms using zebrafish inspires novel strategies for infectious disease treatmen…
