26 augustus 2011: Klimaatverandering lijkt ongunstig voor giftige blauwalgen (persbericht NWO)
De aarde warmt op door stijgende kooldioxide-concentraties in de atmosfeer. Onderzoekers hebben ontdekt dat deze toename in kooldioxide de overlast kan verminderen van de giftige blauwalg, een bacterie die 's zomers veel voorkomt in Nederlands zwemwater. Bij hogere temperaturen groeit blauwalg beter, maar door stijgende kooldioxide-concentraties verdringt de niet-giftige variant van blauwalg zijn schadelijke broertje. Dit blijkt uit door NWO gefinancierd onderzoek.
1 juli 2010: Presentatie van 'spetterend' boek: Als water je lief is
NIEUWERSLUIS (Utr.) – Als water je lief is heet het. In dit boek vertellen wateronderzoekers van jong tot oud over hun geliefde werk. Al vijftig jaar bestuderen de onderzoekers van villa Vijverhof in Nieuwersluis het zoete water om de natuur te begrijpen. Van dichtbij – in de plas Zwemlust of de Loosdrechtse Plassen bijvoorbeeld – tot ver weg in Afrika of op Spitsbergen. Deze kennis komt ook van pas bij het herstellen en het behouden van de natuur.
31 maart 2010: Voorspelbaarheid van planktongemeenschappen in een veranderende wereld
Nieuwersluis (31032010)
Van 7 tot en met 9 april 2010 organiseert het Nederlands Instituut voor Ecologie (NIOO-KNAW), onderdeel van de Koninklijke Nederlandse Akademie van Wetenschappen (KNAW), in samenwerking met Wageningen UR het KNAW Colloquium ‘Predictability of plankton in an unpredictable world’.

Can bird distributions explain freshwater snail distributions?
Key words
GIS, spatial analyst, distributions, comparison, freshwater snails, waterbirds
General context
New ponds and wetlands are often colonized rapidly by all kinds of small aquatic organisms. This suggests these organisms can easily disperse across land between suitable habitat, despite that a lot of species can hardly survive out of the water and certainly not move across land on their own. However, they are frequently found in new wetlands, desert oases and are often widespread around the world. How do they get there?
Freshwater snail characteristics and their potential to be dispersed by birds
Key words
Bird-mediated dispersal, freshwater snails, species characteristics, experiments.

The role of movement decisions in determining species coexistence (Alleen Engelse tekst)
The ability of animals to move among resource patches and exploit them is one of the most important factors controlling consumer population sizes and diversity. Nutrients in aquatic environments are mixed along a vertical gradient, which can influence migration of zooplankton. Also, there is a tradeoff associated with movement decisions, when local resources are simultaneously depleted by competitors or when there is a predation risk involved in making movement decisions. This can potentially affect the assembly of local consumer communities.
