Sperm biology and evolution (thesis/internship projects)
Sperm are critical to successful fertilisation in sexually reproducing animals. The function of sperm – to find and fertilise ova – is universal throughout the animal kingdom, yet the sperm cell is the most morphologically diverse cell type known. -
Light on Nature
We produce more and more light at night. Virtually everybody in Europe or the US lives in a light polluted place: all areas where artificial light always exceeds the light of the moon and the stars. These areas expand with about two percent per year, while already light polluted areas become even brighter at night. -
Licht op Natuur / Licht op Landschap
Het wordt steeds lichter 's nachts. Bijna iedereen in Europa en de VS woont op een plek die als 'lichtvervuild' kan worden aangemerkt: daar is is ons eigen licht altijd sterker dan het licht van de de maan en de sterren. Elk jaar neemt dat gebied met twee procent toe, terwijl de al lichte plaatsen nog lichter worden. -
Impression of the King's visit to NIOO
Earlier this month, His Royal Highness King Willem-Alexander paid a working visit to the Netherlands Institute of Ecology (NIOO-KNAW). The visit included a tour, an introduction to NIOO's three major research themes, and a number of hands-on ecological measurements and experiments in which the King took part. -
Koning op werkbezoek bij het NIOO
Koning Willem-Alexander bracht vandaag een werkbezoek aan het Nederlands Instituut voor Ecologie (NIOO-KNAW) in Wageningen. Naast een rondleiding kreeg de Koning uitleg over de onderzoeksthema's van het NIOO én nam hij deel aan een aantal praktische metingen en experimenten. -

Microbial Networks controlling soil greenhouse gases emissions
Soils are considered principally non-renewable resources. Soil ecosystem services have a large impact on numerous societal demands and are of high economic importance. Within the area of sustainable agriculture, it is expected that agricultural production will increasingly rely on the natural nutrient retention and recycling capabilities of soil. This project seeks to provide a fundamental scientific understanding of soil functioning and the resulting ecosystem services in Brazilian and Dutch bio-economies based on innovative microbial ecology and soil science studies. Focus is in sugarcane crop production systems by linking soil microbial composition and functioning, waste residues recycling, fertilizers, soil factors and greenhouse gases (GHG) emissions through integrating and complementing the strong expertise of Brazilian and Dutch researchers from different areas of agronomy, soil sciences, plant nutrition, biogeochemistry, soil ecology, microbial ecology, ecological genomics, molecular ecology and bioinformatics. We will quantify the microbial functional groups and microbial abundance of C and N cycle genes and measure GHG emissions (CO2, CH4 and N2O) from soils during the productive cycle of the plant under different management practices and verify the temporal and spatial variability of these emissions in the evaluated treatments with different concentrations of sugarcane vinasse residue combined with N mineral fertilizers in combination with straw additions, and determine the conditions under which such GHG emissions can be counteracted, or minimized most. The proposed project will enhance fundamental scientific understanding of the interactive role of the microbial networks operating in soil and the consequences of bio-based agricultural management practices for the functioning of soil systems. -
Artificial light
Nocturnal illumination leads to a permanent disturbance of natural habitats and there is accumulating evidence for – often negative – impact of artificial light in an increasing number of species.
