Abstract Climate change affects plant phenology culminating in temporal shifts such as earlier or later reproduction, detected by the analyses of long-term time series. Phenological changes have serious consequences for both animals that rely on plants for food resource, and for plant communities that undergo alterations in their dynamics and dispersion that ultimately alter species' composition and geographical distribution. The effects of climatic change on tropical plant phenology are still poorly understood mainly due to the lack of long-term studies. Most phenological data from tropical regions are restricted to local scales and short periods of time (1-3 years). This project proposes to apply an alternative approach to understand and predict potential effects of climate change in the tropics. To do it so, we will perform ecological niche modelling combining phenological information and occurrence records extracted from c. 15,000 herbarium records for 50 species of Neotropical Myrtacecae (Myrteae tribe). Myrtaceae is one of the most important families of the Atlantic rainforest, a biodiversity hotspot. We will predict size, displacement and direction of change in the geographical distribution of Myrtaceae in light of future global warming scenarios. The methodological novelty here is to incorporate phenology into ecological niche models to predict species sensitivity to global changes and to depict the relationship between phenological plasticity and species range. In addition, considering the reconstruction of Myrtaceae evolutionary relationships, we will assess the phylogenetic signal in phenological and distributional traits to identify clade sensitivity to climate change. Our study will provide a comprehensive assessment of how climate change may affect future functioning and dynamics of tropical forests. (AU) | |
