The plant hormone auxin plays a central role in the growth and development of plants. Auxin acts in a concentration dependent manner and polar cell-to-cell transport of this hormone determines its distribution in the tissues of plants. This polar auxin transport is mediated by several families of auxin…

Synthesis and application of chemical biology tools to study immunomodulatory signaling lipids.

Large carnivore population is globally declining as a result of the fragmentation of habitat, large prey depletion and retaliatory killing by pastoralists.

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).

Undoubtedly, climate change and increasing human populations will affect Africa’s wildlife – but how exactly? And what can be done to conserve nature? Michiel Veldhuis formulated five testable hypotheses of what might happen and now investigates how the UN Sustainable Development Goals can be achieved.…

Do sustainability values play a role in motivating people to act for biodiversity in successful projects and in successful leadership action? And how could these values be incorporated in current economic valuation methods?

How has early development in R. ocellatus been modified as a result of its parasitic embryonic lifestyle?

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.

What is movements and corridors of the Bornean pygmy elephant in Sebuku forest? What is the nature of human-elephant conflict in Nunukan District in time and space? What are the diets of the Bornean elephants related to crop raiding?

This liber amicorum is a tribute to Prof. dr. ir. Hans H. de Iongh, associate professsor at the Institute of Environmental Sciences (CML) of Leiden University and guest professor at the University of Antwerp, on the occasion of his retirement on 27 October 2016.

Influenza CD8(+) T-cell epitopes are conserved amongst influenza strains and can be recognized by influenza-specific cytotoxic T-cells (CTLs), which can rapidly clear infected cells. An influenza peptide vaccine that elicits these CTLs would therefore be an alternative to current influenza vaccines,…

How can zebrafish research help understanding human diseases?

We study the link between the acoustic, behavioral and physiological health of birds and prominent pollution factors. We aim to explore causation through experimental studies on detrimental factors like traffic noise, particulate matter and chemical toxins. Our primary target is scientific progress…
