Abstract

Ecosystem services are those ecological functions and processes that directly or indirectly benefit human wellbeing. The regulation of agricultural crop pests is a particularly crucial service in tropical regions where insect-pests cause considerable economic damage. Despite demonstrated links between anthropogenic drivers of environmental change (e.g. land-use change) and biodiversity decline, we have little predictive understanding on how environmental change influences ecosystem service provision. The overall objective of this project is to (i) investigate how landscape forest cover and matrix type composition affect the functional and phylogenetic diversity of bird communities in the Atlantic Forest and, (ii) to analyze how these changes on bird community structure subsequently affects the avian regulation of 'spittlebugs' (Homoptera: Cercopidae); a key insect pests of forage grasses. With a well-replicated study design, we will quantify both avian biodiversity within 30 focal landscapes (n=15 for both coffee and pasture) evenly distributed across a forest cover gradient (5-60%) to verify the changes in the bird communities structure following the habitat loss; and, to quantify avian contribution to 'spittlebug' regulation, we will analyses the relative avian diversity to observed pest prevalence in the landscapes with pasture matrix (n=15), and conduct a series of highly replicated manipulative experiments designed to quantify the per capita contribution of an avian focal group to this pest regulation. The expected results will both inform how landscape and community structure interact to influence pest control services, could be applied in improving pasture's quality. (AU)
