Plant gene expression plasticity and adaptation to climate change
One effect of climate change is that plants are exposed to increasing local variation in weather conditions, including more episodes of heat stress. Should plants evolve to perform better at high temperatures, or should they become more plastic and cope with a broader range of temperatures? This project compares a large panel of duckweed genotypes for genetic differences in thermal plasticity in gene expression. Because duckweeds are the fastest growing plants in the world, we can use experimental evolution approaches to test if more plastic genotypes have a selective advantage when temperature environments become more variable. -
Botanical records through a social lens
This collaborative project is led by Folgert Karsdorp of the KNAW Meertens Institute, and investigates the social biases and cultural aspects of historical botanical records (that is, citizen science avant la lettre). In collaboration with FLORON, our contribution to this project is to implement a case study that explores historical botanical records from the Netherlands to characterize patterns of distribution and abundance of Asteraceae species in cities through time. We aim to let these historical records inform us about which species are winners and which are losers of the urbanization process. This can provide unique information on the plant traits that mediate successful adaptation to urbanization. -
ECORAMA – Ecology and evolution of species range margins
This is a collaborative project that is led by John Pannell and Shengman Lyu at the University of Lausanne. The project investigates the genetic, demographic and evolutionary processes that determine species range margins, using Mercurialis annua as a model species. Our contribution to this project is to set up and maintain a field experiment in which experimental plant populations of different admixture histories are monitored for performance at Wageningen, which is at the current distributional range margin of the species. -

Restoring and rewilding ecosystems
It is a topical issue and has long been a research interest of NIOO: how do you restore nature? For example, former farmland can be made more suitable for nature again, and areas connected to each other. This approach could also help to mitigate the consequences of climate change. Furthermore, a growing amount of knowledge about rewilding has become available in recent years. It has become clear that, in the long run, rewilding yields strong ecosystems with more biodiversity. -
Ecosystemen herstellen en verwilderen
Het is een actueel onderwerp en al lang een onderzoeksinteresse van het NIOO: hoe kun je natuur herstellen? Voormalige landbouwgrond krijgt bijvoorbeeld weer een natuurfunctie en gebieden worden met elkaar verbonden. Dit kan ook helpen om de gevolgen van klimaatverandering op te vangen. De laatste jaren komt bovendien steeds meer kennis beschikbaar over ‘rewilding’. Het levert op de lange termijn sterke ecosystemen op met een grotere biodiversiteit, zo blijkt.
