Impact of nutrients
Nutrient availability in natural ecosystems has increased due to anthropogenic activities like spill-over from agricultural ecosystems. In the Netherlands, this has led to the acidification of natural areas for example. At NIOO, we aim to understand the impact of nutrients on natural systems in more detail, to help to bring back the balance. -
Greenhouse gases
Climate change is amplified by greenhouse gas emissions. At NIOO, we work on the fundamental understanding of how gases such as methane, carbon dioxide and nitrogen dioxide influence ecosystems. Our knowledge of carbon and nitrogen cycles provides insight into the potential of greenhouse mitigation tools. In a Dutch freshwater lake or the soil of a tropical rain forest. -
Climate change impacts on harmful algal blooms
Harmful cyanobacterial blooms produce toxins that are a major threat to water quality and human health. Blooms increase with eutrophication and are expected to be amplified by climate change. Yet, we lack a mechanistic understanding on the toxicity of blooms, and their response to the complex interplay of multiple global change factors. Bloom toxicity is determined by a combination of mechanisms acting at different ecological scales, ranging from cyanobacterial biomass accumulation in the ecosystem, to the dominance of toxic species in the community, contribution of toxic genotypes in the population, and the amounts of toxins in cells. -
Inaugural lecture by Dedmer van de Waal
Op donderdag 6 juli houdt Dedmer van de Waal zijn oratie als bijzonder hoogleraar Aquatische Functionele Ecologie aan de Universiteit van Amsterdam. -
Discovering methane eating mycobacterium
Join the Pint of Science lecture where Paul Bodelier and Chrats Melkonian tell us all about their recent discovery of Mycobacterium (a type of immobile, rod-shaped bacteria) that live on eating methane. Hear what we can learn from these microbes and how we can use that to tackle the issues facing methane in our atmosphere today. -
New greenhouse gas-eating bacteria found in highly acidic sulphur cave
A team of ecologists and microbiologists that includes NIOO's Paul Bodelier has identified a unique organism in samples from a Romanian cave nicknamed 'Stinky Mountain'. The novel bacteria can grow on methane, an important greenhouse gas that contributes to global warming. -
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. -

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.
