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. -
NIOO Theme Climate change
We are in the midst of a climate crisis. Our climate system is undergoing a dramatic number of changes, many of which can be attributed to anthropogenic influences, including greenhouse gas emission-induced changes to global surface temperatures, precipitation, glacier mass loss, sea levels, salt intrusion, and ocean heat content. -
Elly Morriën and Emilia Hannula awarded Teylers Foundation gold medal
Emilia Hannula and Elly Morriën have been awarded the Teylers Foundation’s gold medal at a ceremony in Haarlem. The two soil researchers - who both did their PhD research at NIOO - won an essay competition set by the foundation. -

Climate change
Our climate system is undergoing dramatic changes. We use our expertise to understand the impact on biodiversity, and the capacity of natural systems to help mitigate climate change. -
Klimaatverandering
In hoeverre kan natuur weerstand bieden tegen klimaatverandering? Het NIOO onderzoekt de ecologische gevolgen, ook voor advies aan beleidsmakers en anderen. -
Testing early warning signals for crises, in lakes
Wouldn't it be great if we could tell the state of an ecosystem or the like - healthy or heading for a crisis - by keeping track of a few key signals? Thanks to the theory of ‘tipping points’, that’s not unthinkable. Now a team of researchers led by Alena Gsell of the Netherlands Institute of Ecology (NIOO-KNAW) has tested early warning signals: in lakes. In the Early Edition of PNAS online, they conclude that predicting works...but not yet in all cases. -
Alarmsignalen voorspellen naderende crisis - nu ook in de praktijk
Een crisis willen we graag kunnen voorspellen. De theorie van ‘kantelpunten’ biedt daarvoor goede aanknopingspunten. Voor het eerst testte een internationaal team van NIOO-onderzoeker Alena Gsell de alarmsignalen uit in de praktijk, met meren. Het bekende wetenschappelijk tijdschrift PNAS publiceert deze week de resultaten alvast online: “Voorspellen lukt, maar nog niet overal.” -
Extinction of Pleistocene herbivores induced major vegetation and landscape changes
The extinction of large herbivores such as mammoths could explain massive prehistoric changes in vegetation and landscape structure, with major implications for our understanding of present-day ecosystems. Modern and paleo-ecologists joined forces in an international study led by the Netherlands Institute of Ecology (NIOO-KNAW). The results are being published online by PNAS this week. -
Uitsterven grote planteneters veroorzaakte enorme veranderingen in landschap
Het uitsterven van grote planteneters zoals mammoeten blijkt ingrijpende prehistorische veranderingen in plantengroei en landschap te verklaren. Die kwamen dus niet alleen door klimaatverandering, zoals eerder gedacht. De gevolgen zien we vandaag de dag nog, zoals de toegenomen kans op natuurbranden en een verstoring van de voedingsstoffen-kringloop. Een internationaal team onder leiding van het Nederlands Instituut voor Ecologie (NIOO-KNAW) publiceert dat deze week in PNAS.
