Merrin Whatley seeks to elucidate how aquatic invertebrate communities are structured by environmental drivers (i.e. filters) in intensively managed agricultural drainage ditches in the province of North Holland, the Netherlands. As the greatest density of drainage ditches occur in peatland regions which are also remnants of the original wetlands, peatlands are the focal point of Whatley’s thesis. Key questions include: what are the key environmental drivers determining aquatic invertebrate community composition in agricultural ditches? What are the underlying mechanisms underlying the response of aquatic invertebrates to these environmental drivers? And how can management practices be adjusted to improve ecological conditions in these agricultural ditches?
