Biodiversity is non-homogeneously distributed in space, time and among lineages. It is imperative to move past phenomenological descriptions of biodiversity, to explore what are the underlying factors controlling changes in speciation and extinction rates. Most macroevolutionary studies have focused on large spatial and temporal scales, but macroevolutionary patterns should emerge from me…
Temporal, spatial and among lineage differences in biodiversity are trademarks in the history of life. Documenting how the number of species varies is a first order description, but to fully understand biodiversity we also need to understand how speciation and extinction rates vary over time or among lineages, and what factors control the dynamics of such rates. The last decade has seen a…
Is the world full of species? The intuition of a finite limit to the diversity of Life on Earth appeals because Earth is a finite object. It therefore seems logical that there is some limit to the number of species that can co-exist in the different biomes. If this limit exists, then which environmental, ecological and biological processes determine it? Population biologists call such a l…
Despite the great interest in biodiversity, there are many unanswered questions regarding the patterns and processes that affect the diversity of a given clade or geographical region. This is to some extent due to the lack of understanding of diversification dynamics, which in the end will determine the number of species. Diversity dynamics studies have been traditionally done by paleonto…
Most studies that seek to understand species diversification in deep time scales, including those focused on understanding the role of clade competition, have been done at large spatial scales. Although this is the typical approach in macroevolutionary studies, species interactions happen at local scale, and the large-scale patterns that we described should emerge from mechanisms acting a…
One of the goals of evolutionary biology is to understand how diversity varies over time, space and among lineages. On a global scale, species richness is the result of the balance between speciation and extinction rates, and on a more restricted spatial scale, also by the immigration rate. Previous works suggest the existence of a strong correlation between the average rates of speciatio…
Abiotic factors are often treated as the main factor that regulate the origination of biological diversity on a geological scale. However, new evidence in favor of biotic components has revived the discussion about the role of ecological interactions in speciation and extinction dynamics. With this theoretical debate in mind, we propose to evaluate the effect of biotic and abiotic factors…

The fossil record is undoubtedly the most direct way to estimate speciation and extinction rates, but it might be spatially and temporally incomplete and show variation in preservation among lineages. Understanding what factors might affect the recording quality should allow us to better interpret macroevolutionary inferences and guide us in the development of future tools designed to dea…
Biological diversity is unevenly distributed across regions, evolutionary lineages, and through time. The description of how speciation and extinction rates change (through time and among regions or lineages) represents a first attempt to explain biodiversity dynamics, however, we need to understand which factors drive changes in such rates to fully comprehend it. The regulators of biodiv…
Knowing the phylogenetic relationship among lineages allows us to study patterns and processes of evolution and take into account historical factors that might be responsible for traits shared among closely related taxa. The acknowledgment of evolutionary relatedness has changed the way we ask biological questions in a fundamental way. Incorporating the history of populations and species …

A recurrent pattern found in the fossil record is the replacement of entire clades by ecologically similar lineages. These phenomena suggest ecological interactions between taxa in different clades may interfere with the evolutionary dynamics of a given lineage. In this project we propose to develop diversification models that include mechanistic components likely to underlie these macroe…
Body size is known to strongly influence many aspects of the biology of a species. The dynamic of body size evolution has been widely studied using two approaches: analysis of taxonomic fossil occurrences, and comparative analysis using a phylogenetic framework for extant species. The analysis of the fossil record is the most direct way of investigating the evolutionary dynamic of a linea…
