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. -
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. -
Fireworks have long-lasting effects on wild birds
An international team of scientists has examined the long-term effects of fireworks on wild birds. -
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. -
PhD defence Melanie Lindner: Bird reproduction in a warming world
Melanie Lindner will defend her PhD thesis titled "Avian seasonal reproduction in times of global warming: Insights from evolution, ecology and (epi-)genomics" -
Thesis defence Bernice Sepers: the role of DNA methylation variation in avian personality
On 28 October, Bernice Sepers (Animal Ecology) will defend her thesis on 'Behavioural epigenetics: insights into the role of heritable and induced DNA methylation variation in avian personality' at Wageningen UR. -
It takes more than two to tango: Microbial communities influence sex and reproduction in animals
The reproductive tracts of males and females contain whole communities of micro-organisms. These microbes can have considerable impact on (animal) fertility and reproduction, as shown by Melissah Rowe from the NIOO-KNAW. -
Frisian lapwings fan out across Europe in winter
Northern lapwings are easy to spot during the breeding season, with their noisy aerial acrobatics. But as research led by the Netherlands Institute of Ecology (NIOO-KNAW) shows, lapwings that breed virtually next to each other in spring may spend their winters thousands of kilometres apart. As a survival strategy, it's not enough to stop the species' ongoing decline. -
Extreme weather has greater impact on nature than expected
An oystercatcher nest is washed away in a storm surge. Australian passerine birds die during a heatwave. A late frost in their breeding area kills off a group of American cliff swallows. Small tragedies that may seem unrelated, but point to the underlying long-term impact of extreme climatic events. In the special June issue of Philosophical Transactions of the Royal Society B, NIOO researchers launch a new approach to these 'extreme' studies. -
Nocturnal light makes birds change their behaviour
Songbirds change their behaviour and timing when nestboxes are exposed to artificial light at night. "They become light sleepers, literally and metaphorically", says Maaike de Jong (NIOO-KNAW). She successfully defended her thesis on the effects of different colours of light at Wageningen University on Friday. The most surprising effect she's found? Some birds are forced to become more monogamous...
