Costs of scaring grass-eating barnacle geese often outweigh the benefits
At the current population sizes, the practice of scaring geese off pastures in the province of Friesland probably ends up costing more than it saves. Ecologist Monique de Jager and colleagues from the Netherlands Institute of Ecology (NIOO-KNAW), Utrecht University, Wageningen University & Research and the University of Amsterdam conclude this based on a model study, that was conducted as part of the Dutch contribution to European goose management. The results suggest that scaring geese is cost-effective only when there are few geese in the area. -
Bewick’s swans choose wintering areas based on the weather
Bewick’s swans fly less far during their autumn migration when the weather is warm. Climate change has therefore led to a shift in their common wintering areas. Now, for the first time, bird researchers have been able to use long-term GPS data to pinpoint the specific choices that individual swans make. -
Symposium Migratory birds under pressure
On Thursday 7 September 2023 our Animal Ecology department is organising a symposium on migratory birds under pressure, followed by the PhD thesis defence of Kees Schreven the next day. -
PhD Thesis defence Kees Schreven: range expansion in Arctic-breeding geese
On Friday 8 September 2023, our colleague Kees Schreven will defend his PhD thesis "Geese colonising New Land: causes and mechanisms of range expansion in an Arctic-breeding migrant". -
The relationship between yield loss and grazing pressure: implications for goose management
Grazing by geese can cause a lot of damage to agricultural crops. Goose management aims to reduce such damages, for example by actively reducing population sizes. -
More grazing geese does not always mean less harvest
An international team led by the Netherlands Institute of Ecology (NIOO-KNAW) looked at the impact of different goose species and the number of geese on agricultural damage in the province of Friesland. -

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.
