Data from: Cranial evolution in the extinct Rodrigues Island owl Otus murivorus (Strigidae), associated with unexpected ecological adaptations

Antoine Louchart, Anaïs Duhamel, Julian Hume, Pauline Guenser & Céline Salaviale
Island birds that were victim of anthropic extinctions were often more specialist species, having evolved their most distinctive features in isolation. Here we studied a fossil cranium of the ‘giant’ extinct scops owl Otus murivorus from Rodrigues Island (Mascarene Islands, southwestern Indian Ocean), to determine any potential unique characters. The fossil and extant strigids were imaged through x-ray microtomography, providing 3D views of external and internal (endocast, inner ear) cranial structures. Geometric morphometrics and analyses...

IS-mediated mutations both promote and constrain evolvability during a long-term experiment with bacteria

Jessika Consuegra, Joël Gaffé, Richard E. Lenski, Thomas Hindre, Jeffrey E. Barrick, Olivier Tenaillon & Dominique Schneider
The long-term dynamics of IS elements and their effects on bacteria are poorly understood, including whether they are primarily genomic parasites or important drivers of adaptation by natural selection. Here, we investigate the dynamics of IS elements and their contribution to genomic evolution and fitness during a long-term experiment with Escherichia coli. This data set includes the Rmd file to analyze the genomic and metagenomic data (Tenaillon et al. 2016 and Good et al. 2017)...
