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. -
Large herbivores can bend the curve of biodiversity loss in tropical forests
A 10-year experiment in Brazil’s endangered Atlantic Forest, led by NIOO-researcher Nacho Villar, has found that there's less biodiversity loss in areas where large herbivores can roam free. -
Minder biodiversiteitsverlies in bedreigd bos door grote grazers
In bosgebieden met grote grazers is er minder biodiversiteitsverlies. Dat is de conclusie na een tienjarig experiment in Brazilië, geleid door Nacho Villar. -
Natuuronderzoek en maatschappij
Een duurzamere maatschappij is een noodzaak voor ons allemaal. Ecologische kennis is daarvoor onmisbaar. Biologische gewasbescherming en het onderzoek op de Marker Wadden. Of de gevolgen van giftige algen, kunstlicht en microplastics. En hoe kunnen micro-organismen Afrikaanse boeren helpen en wij de natuur herstellen? -
Een gebouw dat leeft
Het Nederlands Instituut voor Ecologie (NIOO-KNAW) wilde een zo duurzaam mogelijk gebouw, in allerlei opzichten, als nieuwe vestiging. -
Invasive Species
Large-scale changes in climate and land use create opportunities for species from other parts of the world. What is the impact of these species on the local ecology, and when do they become ‘invasive’? -
Invasieve soorten
Door grootschalige veranderingen in klimaat of landgebruik krijgen soorten uit andere werelddelen kansen. Wat is de impact van deze soorten op de lokale ecologie, en wanneer worden ze 'invasief'? -
Researchers united on international road map to insect recovery
It’s no secret that many insects are struggling worldwide. But we could fix these insects’ problems, according to more than 70 scientists from 21 countries. Their road map to insect conservation and recovery is published in Nature Ecology & Evolution this week. From urgent ‘no-regret’ solutions to long-term global comparisons. -
Internationale wetenschappers presenteren samen masterplan voor insectenherstel
De ‘road map’ voor insectenbehoud en -herstel van ruim 70 wetenschappers uit 21 landen staat deze week in het tijdschrift Nature Ecology & Evolution. -
Loss of soil carbon due to climate change will be "huge"
55 trillion kilograms: that's how much carbon could be released into the atmosphere from the soil by mid-century if climate change isn't stopped. And all in the form of greenhouse gases such as CO2 and methane. Tom Crowther (NIOO-KNAW) and his team are publishing the results of a worldwide study into the effects of climate change on the soil in the issue of Nature that came out on 1 December.
