Editorial work

Expertise

To gain a better understanding of the behaviour and functioning of animals, I use rate of energy intake and the economy of its use for life processes as an index of fitness. This is prompted by the fact that all animals must obtain and convert energy from their environment and use it for maintenance, growth and reproduction. Other potentially limiting factors apart from energy (e.g. nitrogen, water) are also quantified. My theoretical, experimental and observational eco-physiological studies involve mainly higher vertebrates, notably omnivorous and herbivorous birds, and focus mainly on reproductive, migratory and foraging behaviours. I enjoy the challenge of trying to extrapolate from individual behaviour to population dynamics and community functioning.

My research projects are increasingly conducted within a freshwater plant-animal interaction framework. Besides studies on protein and energy turnover and body store dynamics my research interest includes temporal and spatial variation in diet choice (partly through stable isotope techniques) and the role birds (and notably waterfowl) play in connecting life at distant sites.

The ecology of migratory birds and its relevance to the spread of influenza viruses  

In 2003, with the outbreak of highly pathogenic avian influenza in the Netherlands (2003) we received a major reminder of the threats of avian influenza to animals and man. The threat has not subsided; a highly pathogenic avian influenza virus (H5N1) recently spread from Southeast Asia to Russia, Eastern Europe and Turkey, and has killed 85 indiviuals out of 160 infected. Many people fear that this virus could cause a new pandemic similar to the Spanish Flu pandemic, which caused an estimated 40 million casualties worldwide in 1918. It has been speculated that the spread of the H5N1 virus is facilitated by migratory waterfowl, which would be bad news for The Netherlands being a hot spot for these animals with some visiting species easily outnumbering the human population. 
 

 

 

Although virologist should importantly be dealing with this paramount issue, the ecology of the viruses and their hosts may significantly determine the chances and severity of an influenza pandemic. It is the latter aspect that has my specific interest and which has led me to launch a number of projects in co-operation with the groups of Ron Fouchier (Erasmus University) and Hans Heesterbeek (University of Utrecht).
