6 Spectrometry (ICP-MS) to determine the isotopic composition of strontium (Sr) in the coffee bean. The results obtained demonstrated that the isotope ratios of Sr and O of the coffee bean are a promising tool for its traceability, as these elements reflect the local geology and hydrology. In order to expand the understanding of how environmental factors determine the isotopic composition of the different elements on the green coffee bean, further research was developed focusing the region of Hawaii. The results allowed for the differentiation of the different coffee-producing regions of Hawaii. In addition, IRMS was also applied to measure the oxygen isotopic composition of the caffeine molecule (δ 18 O caff ), previously extracted from the green coffee bean. O isotopes of caffeine molecule originate from the metabolic water of plant tissues, and accordingly results showed that this organic specific compound may be relevant for studies on the coffee plant ecophysiology. Carla Rodrigues wishes to thank Fundação para a Ciência e a Tecnologia for a grant (SFRH/BD/28354/2006) and SIBAE (Stable Isotopes in Biosphere-Atmospheric-Earth System Research) programme (COST Action ES0806) for a STSM (Short Term Scientific Mission) grant. Financial support by the Austrian Science Foundation (FWF START grant 267 N11) is gratefully acknowledged. This work was financed by the project Pursuing Green Coffee Geographic Origin Discrimination through Relations between Isotopes and Environmental Factors (IsoGeoCoffee) from FCT (PTDC/AGR-AAM/104357/2008). PA 303 MANAGEMENT EFFECTS ON PHOTOSYNTHETIC CAPACITY AND LEAF LEVEL NUTRITION IN TROPICAL SHADE AGROFORESTRY SYSTEMS: THE CASE OF COFFEE IN COSTA RICA CAMPBELL, Leslie*, SOTO, Gabriela**, ISAAC, Marney E.* *University of Toronto, Toronto, Canada, ** Centro Agrono mico Tropical de Investigacion y Enseñanza, CATIE, Costa Rica. Growing concern regarding the long-term environmental sustainability of intensive C. arabica (coffee) production is increasing the re-evaluation of more sustainable methods of coffee production. Agroforestry coffee production methods present one potentially viable alternative, but further research on interspecies shade and nutrient interactions particularly at the leaf level is needed to inform efficient and effective system design. A study was undertaken to compare the adaptation of resource acquisition strategies of 10 year old coffee plants under full sun and legume (Erythrina sp. and Chloroleucon sp.) shaded conditions in combination with organic and conventional fertilization regimes at a Costa Rican experimental research site. Shade levels below biannually pruned, conventionally fertilized Erythrina elicited the strongest adaptive response in coffee as evidenced by improved photosynthetic performance at both high (A max = μmol photons m -2 s -1 ; P = ) and low (light compensation point = 17 μmol photons m -2 s -1 ) light levels relative to coffee grown beneath Chloroleucon or full sun. These coffee plants associated with Erythrina were also found to have a higher average leaf area (39.29 cm 2 ; P = ), and dry mass (0.210 g; P = ) than any of the other treatment combinations tested. Organic fertilization was found to significantly improve soil surface available P levels in comparison to conventional fertilization (P = ) regardless of shade species, though conventional fertilization elicited a stronger shade response in the coffee plants. Based on study findings, shade mechanisms appear to be the most important drivers of aboveground coffee adaptation in coffee agroforestry systems, though proper soil nutrient management in low nutrient environments also appears to augment coffee response to microclimate conditions. 365 THE 24TH INTERNATIONAL CONFERENCE ON COFFEE SCIENCE
