My name is Peiyu Zhang, from the Aquatic Ecology department of Netherlands Institute of Ecology (NIOO). I am a first year PhD student.

I am going to do some research about the influence of climate warming on trophic interactions in aquatic foodwebs. The prevalence level of herbivory in aquatic animals strongly increased towards the equator. The drivers may be the evolutionary time or the temperature. We need to test if the major driver is the temperature. If temperature is an important driver, this will has important implications for the impact of climate warming on plant consumption.

The palatability and quality of plants decrease towards the equator. The stoichiometry theory predicts that a decreasing C: N ratio in plants corresponds generally with increased plant consumption, and the C: N increases towards high latitudes, but there is more plant consumption in lower latitudes. So the C: N ratio of plants may not be a reliable predictor for the plant consumption.
