Phenotypic plasticity and genetic adaptation of plant functional traits on global scales
In light of climate change, it is crucial to determine whether plant species can adapt to future climates to avoid extinction.

Calcium-dependent regulation of auxin transport in plant development
The plant hormone auxin regulates plant growth and development through polar cell-to-cell transport-generated maxima and minima. PIN FORMED (PIN) auxin efflux carriers determine the direction of this auxin flow through their asymmetric placement on the plasma membrane (PM).

Bedoelde en onbedoelde effecten
Vaak krijgen daders korte gevangenisstraffen opgelegd. Dikwijls gaat het vóór de straf al niet goed met deze daders, bijvoorbeeld bij het vinden van een baan. Een korte detentie kan de toch al kwetsbare uitgangspositie van daders verslechteren. Doorlopende begeleiding na een straf verdient daarom aandacht.…

interactions in Jacobaea vulgaris: zooming in and zooming out from a plant-soil feedback perspective
In this thesis, I focused on studying the above- and belowground interactions of J. vulgaris from a plant-soil feedback (hereafter, PSF) perspective. I investigated the temporal variation of negative PSF and examined the effects of root-associated bacteria on plant performance and aboveground herbiv…

A meta-analysis of wetland plant traits in relation to the strategies of wetland plants and the impacts on ecosystem functioning
What are trait-trait relationships in wetlands? To what extent the so-called leaf economics traits deviate from terrestrial ecosystems? How traits specific to wetland plant relate to plant strategies? What’s the relationship between wetland plant traits to the ecosystem functioning (e.g. productivity,…
