Tree performance is generally considered as the consequence of the interplay between ecological and evolutionary processes. However, the differential effect among species and the portion of those ...

Phylogenetic analysis underpins modern evolutionary biology by constructing trees that illustrate the relationships among species and genes. Gene tree reconciliation extends these analyses by aligning ...

In biology, phylogenetic trees represent the evolutionary history and diversification of species -- the ''family tree'' of Life. Phylogenetic trees not only describe the evolution of a group of ...

The new model focuses on phylogenetic diversity, which is very different from counting species, today's standard measure of biodiversity. The same number of species (three blue circles) can have a ...

Phylogenetic analysis explores the evolutionary relationships between organisms and is a vital foundation for microbial studies. The development of reliable phylogenetic trees is an important step in ...

The area known as the Santana Group in the Araripe Basin in northeastern Brazil has long been an important fossil site, contributing significantly to knowledge of the Cretaceous period. In particular, ...
