RESUMO:

Detect the underlying processes governing broad-scale patterns in biodiversity is a fundamental question in ecology and evolutionary biology. Despite broad-scale a pattern of species richness (SR) is well documented, biodiversity encompass variation in several aspects beyond species richness, such as phylogenetic diversity (PD) and functional (or trait) diversity (FD). While PD embody the differences in phylogenetic relationship among taxa and represents biogeographic and evolutionary histories of communities, FD represent how species are distributed in multidimensional niche space denoted by functional traits. There is a current growing interest on determine the mechanisms that influence the PD and FD because they are fundamental to our understanding of large-scale patterns of biodiversity. In my thesis I will use novel methods and databases on phylogenies and trait information on mammals and birds to investigate the global relationships between PD and FD relationships. In the first chapter I will investigate the relative role of contemporary and historical climate conditions on residuals of the relationships between PD and FD. In this chapter I will account for local and global variations to access how the productivity, seasonality and historic climate stability affect FD/PD residuals. In the second chapter I will explore congruencies in phylogenetic and trait-based community assembly metrics. In this case I will ask whether phylogenetic, trait-based or both approaches explain species composition in local assemblages and the importance of climate stability and stress-gradient hypothesis on the observed patterns. In the third chapter I will investigate the turnover and nestedness components of phylogenetic and functional β-diversity. Accordingly, I will investigate latitudinal patters in using distance-decay approach. Finally, in the last chapter I present novel database on amphibian’s traits: A Functional Trait Database for Amphibians of the World. This database will be useful for future analysis on amphibian’s macroecology and macroevolution.
