Modelling effects on farmland food webs of herbicide and insecticide management I - CB02010
|
Description
This project is one of two (the other is with NERC Centre for Ecology and Hydrology) critically analysing existing food supply/farmland bird response models and modelling approaches. The aim of these contracts is to carry out an analysis of certain critical gaps and to construct a model or models that could be used to extrapolate the effects on farmland birds of herbicide and insecticide management systems on the availability of plant and animal food resources available to foraging birds in the agricultural ecosystem.
Many species of farmland bird have undergone rapid population declines and range contractions in the last 25 years, largely as a result of agricultural intensification. Growing evidence suggests that one important reason for this is that changes in farming practices have had a negative impact on food availability for many birds. There is a growing need to understand the causes of the population declines in order to prevent further declines and to develop management techniques to conserve and enhance bird populations on arable land. |
