Evaluating the relative impact of indirect effects of pesticides and other factors on the demography of a farmland bird - PS2320

Description
The aim of this project is to improve our understanding of the relative impact of the indirect effects of insecticides and other factors, including farming practices, on the population growth rates of a farmland bird, the yellowhammer Emberiza citrinella L. The indirect effect of pesticides on farmland birds may, potentially, be a key issue in the regulatory process for pesticides in the UK. Indirect effects of pesticides may also impact on the Defra Public Service Agreement to reverse the population declines of farmland birds by 2020. The results of this investigation will be disseminated at an open meeting of the Advisory Committee on Pesticides.
Objective
Objective 1.
To quantify the impact of varying arthropod food abundance on the population growth rate of yellowhammers at varying predation levels.

Objective 2.
To quantify the impact of varying arthropod food abundance on the population growth rate of yellowhammers, when adult and first winter survival rates are varied.

Objective 3.
To undertake a scoping study of the assessment of the relative importance of indirect effects of pesticides and other factors, including farm practices, on the demography of yellowhammer populations on farmland.
