The size structure of phytoplankton assemblages strongly influences energy transfer through the food web and carbon cycling in the ocean. We determined the macroevolutionary trajectory in the median ...

Regions with high diversity or many unique species are often assumed to be hotbeds of species origination, but a new theory demonstrates that such places could instead result from the immigration of ...

Analyses of evolutionary dynamics depend on how phylogenetic data are time-scaled. Most analyses of extant taxa assume a purely bifurcating model, where nodes are calibrated using the daughter lineage ...

Brontotheres, or “thunder beasts” – an extinct lineage of herbivorous rhinoceros-like mammals (though more closely related to horses) – evolved their massive multi-ton body sizes as a way to survive ...

Understanding the large-scale processes that shape distributions of species diversity is a long-standing challenge in ecology and can also help set conservation priorities. Regions with highly diverse ...
