A.  aControl of Carapa guianensis phenology and seed production at multiple scalesba five-year study exploring the influences of tree attributes, habitat heterogeneity and climate cues.h[electronic resource]  c2012  aDuring 5 y, we monitored reproductive activity and seed production of Carapa guianensis in two forest types to test the hypothesis that seed production is influenced by multiple factors across scales (regional climatic cues, local habitat heterogeneity and individual tree attributes). Variability in seed production was moderate at the population (CVp =1.25) and individual level (xCVi =1.24). Amixed modelwith a Poisson regression revealed that seed production was explained by variables at all scales. Total seed production was significantly higher in occasionally inundated forests. Diameter at breast height, dbh2, crown cross-sectional area, liana load, density, dry-season rainfall and mean maximum temperature were also significant in explaining seed production variation. Seed production increased with dbh until 40?50 cm, then decreased. Liana load demonstrated a negative relationship with seed production, but only in terra firme forests. Climatic cues (rainfall and temperature parameters) were central to setting overall patterns in reproductive activity and seemed to best explain why years with high seed production were consistent across the two forest types (habitats) examined. Dry-season rainfall was positively correlated with seed production.  aGrowth performance  aPhenology  aPlant breeding  aPoisson distribution  aSeasonal development  aSeedling production  aStatistical analysis  aAnálise estatística  aAndiroba  aCarapa guianensis  aClima  aErva daninha  aFator de crescimento  aFenologia  aFloresta  aPopulação de planta  aProdução de sementes  aReprodução vegetal  aTemperatura  aAnálisis estadístico  aDesarrollo estacional  aDesempeño del crecimiento  aDistribución de Poisson  aFitomejoramiento  aLiana  aProducción de plántulas  aRegressão de Poison1 aKAINER, K.
