Abstract

The cross-habitat spillover process refers to biological fluxes (the exchange of materials or movement of organisms) between different habitat types, which might be the result from both dispersal or foraging movements. These movements occur very often from native habitats into agricultural lands, and when this happen, the spillover is considered an important mediator of ecosystem services provisioning. One recognized example of this is the coffee borer beetle control (the main coffee pest in Brazilian farms) by forest dependent spillover birds. Given that avian cross-habitat spillover may represent an effective alternative of coffee borer beetle control and that this control might be reinforced as a function of the spatial arrangement of both native remnants and coffee plantations, the goals of this project are four fold: 1 - to evaluate the effects of both landscape structure and temporal pulse of coffee borer beetle on avian-cross habitat spillover; 2 - to estimate the impact of forest cover and avian-cross habitat spillover on the coffee borer beetle control; 3 - to estimate the economic impact of avian-cross habitat spillover to the Mogiana and Sul de Minas regions; and, 4 - to simulate the economic impact of avian cross-habitat spillover using different restoration scenarios. In order to respond our questions, we will combine in an unprecedented way in Brazil, experimental exclusion methods with birds' movement monitoring using automated telemetry. The results of this research will contribute for a better understanding of the landscape structure effects on spillover dynamics in fragmented landscapes, as also to quantify the spillover contribution for the coffee borer beetle control, which can subsidize the design and management of sustainable coffee landscapes, in order to ally both agricultural yield and biodiversity conservation.
