Climate change affects plant phenology culminating in temporal displacement such as earlier or later reproduction, with serious consequences for both animals that rely on fertility for food, and for plant communities that undergo alterations in dynamics and dispersal that ultimately change species composition and geographical distribution. The effects of climatic change on tropical plant phenology are still not well understood due to a lack of long-term studies in the tropics to identify changes in phenological responses over time. This project will therefore apply two alternative approaches as tools to understand and predict potential effects of climate change in the tropics, using the Atlantic rainforest and Myrtaceae family as model group. Available phenological data are currently restricted to local scales and short time periods; the first approach will be to assess phylogenetic signal in phenological traits, identifying which tropical families or genera are most sensitive to climate change by presenting more conservative phenology and being confined to a restricted ecological niche. For this analysis, we will use phenological data already collected at 11 Atlantic Forest localities in conjunction with evolutionary reconstructions of these communities. The second approach will combine phenological information and occurrence records based on herbarium collections, subjected to ecological niche modelling. We will focus on the most important family inside this hotspot, Myrtaceae, analysing c. 15,000 specimen records for 70 species (unpublished data). We will predict size, displacement and direction of change in the geographical distribution of this group in light of predicted global warming scenarios. Our study provides a comprehensive assessment of how climate change may affect future functioning and dynamics of tropical forests. (AU)
