AbstractAmazonia’s floodplain system is the largest and most biodiverse on Earth. Although forests are crucial to the ecological integrity of floodplains, our understanding of their species composition and how this may differ from surrounding forest types is still far too limited, particularly as changing inundation regimes begin to reshape floodplain tree communities and the critical ecosystem functions they underpin.

AbstractPredicting drought-induced mortality (DIM) of woody plants remains a key research challenge under climate change. Here, we integrate information on the edaphoclimatic niches, phylogeny and hydraulic traits of species to model the hydraulic risk of woody plants globally. We combine these models with species distribution records to estimate the hydraulic risk faced by local woody plant species assemblages.

Correlated evolution between trait and environment transitions To test whether traits and associated environments have evolved under a model of correlated evolution (H2), we used BayesTraits (version 3.0.2, Pagel & Meade, 2006, 2019) implemented in the R package ‘bayes traits wrapper’ (Griffin, 2018). We focused on trait and environmental variables that showed significant relationships in the PGLS.
