Buzzing decline: Dutch landscape is losing insect-pollinated plants
The Netherlands is losing plant species that rely on pollination by insects. Leiden environmental scientist Kaixuan Pan demonstrates this after analysing 87 years of measurements from over 365,000 plots. The news is alarming for our biodiversity and food security. "75 per cent of our crops and 90% of the wild plants rely on insects." -
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". -
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" -
Sperm biology and evolution (thesis/internship projects)
Sperm are critical to successful fertilisation in sexually reproducing animals. The function of sperm – to find and fertilise ova – is universal throughout the animal kingdom, yet the sperm cell is the most morphologically diverse cell type known. -
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. -
Migratory animals create worldwide ecosystem
WAGENINGEN – In the animal kingdom, travel is key: that is the conclusion of Silke Bauer’s research in a nutshell. The NIOO-ecologist and an Australian colleague list the numerous species that migrate from one location to another. According to the two researchers, the effects of these migrations on world ecosystems have been overlooked. Time to give the billions of geese, locusts, butterflies, herrings and wildebeest that wander the globe their proper due.
