This multidisciplinary minor provides students with knowledge on how and why humans became the way they are. The minor focuses on the evolution of the species Homo sapiens from other hominin lineages and animal ancestors, and on the various factors shaping this process. Not only is human evolution of…

Anthropogenic noise has been shown to affect marine animals in various ways, this may have fitness consequences at individual and population level. This thesis aims to increase insight into the quantification of sound-induced behavioural responses that are relevant to fitness, and into factors that…

Our modern society thrives on chemicals, and demand is only growing with novel chemicals being introduced onto the market. However, with increasing demand, so come potentially increasing ecological consequences of these man-made chemicals.

The effects of anthropogenic noise on interactions between predators and their prey are still little understood.

The deeper understanding of an organism's pathology is important for developing treatments. Over centuries of systematic research, clinical researchers have demonstrated that the more information they acquire about the cellular properties and their organisation in the tissue, the better they can understand…

Carbohydrates, alongside proteins and nucleic acids, constitute a crucial and versatile family of biomolecules present in all life forms. They manifest as monosaccharides, oligosaccharides, and polysaccharides, covalently bonded to proteins and fats. Carbohydrates are integral to plant and arthropod…

Climate change is a challenge for both current and future generations. New biological resources have to be developed in order to meet the demand for energy as well as the demand for food.

In het kader van de Honours Course ‘Crises in Biology’ die plaatsvond van 19 augustus t/m 2 september 2012 in Normandië, bezochten studenten vele geologische interessante locaties. Een van deze bijzondere plekken was de kust van Arromanches. Hier bemachtigden zij een enorm grote ammoniet die ze dinsdag…

As a non-invasive genetic method, eDNA based approaches have become an important component of ecologists' and environmental managers' toolkits for biomonitoring in conservation and an increasingly important source of ecological knowledge.

The cannabinoid receptor type 2 (CB2R) is associated with several inflammatory diseases with an unmet medical need (e.g. Alzheimers, multiple sclerosis, reumatoid arthritis). Development of new chemical biology strategies to study this protein is essential to aid future development of drugs for these…

This thesis describes the synthesis and biochemical evaluation of a variety of cyclophellitol based activity-based probes and inhibitors targeting various endo- and exo-acting retaining glycosidases. In the last two decades a variety of probes and inhibitors for (hemi)cellulose degrading enzymes have…

Docenten spelen een cruciale rol bij het implementeren van onderwijsvernieuwingen. Uiteindelijk hangt het succes van de implementatie af van de manier waarop docenten de vernieuwing vormgeven in hun dagelijkse lespraktijk.

Streptomyces present a valuable platform for natural product discovery. Lugdunomycin is a novel angucycline-derived polyketide from Streptomyces sp QL37, with unprecedented skeleton and antimicrobial activity.

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.

The power of personalized nutrition lies in being able to conduct clinical research on healthy people while capturing metabolic markers sensitive to the impact of environmental and metabolic stressors (e.g. diet, changing sex hormones and the menstrual cycle).

Hybrid zones occur where two species meet and produce offspring (hybrids). Typically, hybrids show a considerable reduction in fitness. In this thesis two hybrid zones are treated.

Waarom houden veel mensen geheim op wie ze stemmen? Op Linda.nl geeft universitair docent Anne Heyer antwoord op die vraag.

‘Legitimacy and Justice’ is een onderzoekscluster binnen het programma ‘Institutions, Decisions and Collective Behaviour’. De wetenschappers die hierin actief zijn houden zich bezig met de legitimiteit en rechtvaardigheid van politieke instituties. Zij kijken in het bijzonder naar de relaties tussen…

The aim of this thesis is to study cell-cell interactions and the development of an assay to explore and quantify the exchange of membrane compounds.

The ability to count is a property not often attributed to materials, despite the abundance of memory in materials. Regardless of how a material stores information, it is often difficult to retrieve exactly ‘what’ a material remembers.

Sound is everywhere in the marine environment and hearing is therefore a very important for stimuli for fish. They use sound for orientation and communication, during migration, aggregation and spawning, but also for detection of prey and predators.
