Coordinated transformations of the labyrinth and occiput during the dinosaur–bird transition

Evolutionary shape changes of the vertebrate semicircular canals (SCCs) are often ascribed to evolutionary transitions in locomotion, including the origin of flight during the dinosaur–bird transition. However, the potential for transformations of braincase architecture to influe...

Habitat Complexity and Seasonal Variation Factors Shape the Polychaete Assemblies Associated with the Holdfast of Lessonia berteroana

Lessonia berteroana is a structuring macroalga that houses a high diversity of benthic invertebrates in southeastern Pacific rocky ecosystems. The present study assessed the diversity and structure of the community of polychaetes associated with the holdfast of L. berteroana at t...

Forest canopy decline under elevated CO 2 during the Paleocene-Eocene Thermal Maximum

Uncertainty remains regarding the impact of rapid anthropogenic warming on forest ecosystem structure, biodiversity, and function. As an analog, we reconstruct forest canopy density and compositional change in Wyoming, USA, through the Paleocene-Eocene Thermal Maximum (PETM), an...
