A multiple isotope approach to human-animal dynamics in the Lesser Antilles across the historical divide

The national dietary guidelines in Australia, Brazil, Ireland, Japan, Portugal, and Slovenia benefit nutrition, environment and animal welfare, Leiden environmental scientists write in the journal One Earth. However, the national guidelines of other countries face trade-offs, negatively impacting at…

Prof. Gilles van Wezel and Prof. Mike Richardson of the Institute of Biology Leiden received €1.4 million to find new antibiotics.

The University of Trento hosts the biennial conference of the International Reynard Society, taking place on September 25-28 2024. Deadline for paper/session submissions: December 31.

As part of the lecture series 'Religion Matters', Sven Gins (RUG) will speak about moving statues and other ingenuous devices in late medieval France. The lecture will take place on Wednesday, March 13, 17:00-18:00.

Anthropogenic noise negatively affects wildlife in a wide range of taxonomic groups.

The center studies the many ways in which issues of law and justice are dealt with in art and literature with a focus on liminal issues and cases. These are issues and cases where law comes to the limits of what it is capable of dealing with and art and literature explore the implications of what is…

This book examines the role of memory in animation, as well as the ways in which the medium of animation can function as a technology of remembering and forgetting. By doing so, it establishes a platform for the cross-fertilization between the burgeoning fields of animation studies and memory studie…

The project aims to explore Eurasian elk's role in the ecosystems of the past and its relationship with humans through analysis of its distribution and habitat in the Netherlands.

We use zebrafish as a model organism to study human development and disease as well as animal welfare and environmental impact.

Pharmaceutical companies, governments and the general public have become increasingly aware that animal models used in drug testing lack vital aspects to serve as an accurate representation of human biology. As models of the human body should become more physiologically relevant, animal models no longer…

In the Drug Research theme, we primarily work with rodents. Rodents, such as mice, are one of the most common laboratory animals. These small mammals are easily housed and exhibit a rapid rate of reproduction.

In this thesis, I study 1) metabolic alterations in tuberculosis related to wasting syndrome in human patients as well as in rodent and fish animal models. 2) effects of the mutation of the leptin gene on cachexia and diabetes in rodent and zebrafish animal models.

As humans we have a tendency to judge certain actions as either right or wrong. Where does our moral sense come from? We found evidence that infants who are only one year old prefer those who comfort as opposed to ignore another who is sad.

During post-embryonic development into adults, animals face an environment that fluctuates constantly. For example, in nutrient availability, temperature, and osmolarity (e.g., salt concentration).

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.

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,…

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…

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.

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.
