  • Bone histology in extant and fossil penguins (Aves: Sphenisciformes) 
    Ksepka, Daniel T.; Werning, Sarah; Sclafani, Michelle; Boles, Zachary M. (2015)
    Substantial changes in bone histology accompany the secondary adaptation to life in the water. This transition is well documented in several lineages of mammals and non-avian reptiles, but has received relatively little ...
  • Earth history and the passerine superradiation 
    Oliveros, Carl H.; Field, Daniel J.; Ksepka, Daniel T.; Barker, F. K.; Aleixo, Alexandre; Andersen, Michael J.; Alström, Per; Benz, Brett W.; Braun, Edward L.; Braun, Michael J.; Bravo, Gustavo A.; Brumfield, Robb T.; Chesser, R. Terry; Claramunt, Santiago; Cracraft, Joel; Cuervo, Andrés M.; Derryberry, Elizabeth P.; Glenn, Travis C.; Harvey, Michael G.; Hosner, Peter A.; Joseph, Leo; Kimball, Rebecca T.; Mack, Andrew L.; Miskelly, Colin M.; Peterson, A. T.; Robbins, Mark B.; Sheldon, Frederick H.; Silveira, Luís Fábio; Smith, Brian Tilston; White, Noor D.; Moyle, Robert G.; Faircloth, Brant C. (2019)
    Avian diversification has been influenced by global climate change, plate tectonic movements, and mass extinction events. However, the impact of these factors on the diversification of the hyperdiverse perching birds ...
  • The evolution of mammalian brain size 
    Smaers, J. B.; Rothman, R. S.; Hudson, D. R.; Balanoff, A. M.; Beatty, Brian; Dechmann, D. K. N.; de Vries, D.; Dunn, J. C.; Fleagle, J. G.; Gilbert, C. C.; Goswami, A.; Iwaniuk, A. N.; Jungers, W. L.; Kerney, M.; Ksepka, Daniel T.; Manger, P. R.; Mongle, C. S.; Rohlf, F. J.; Smith, N. A.; Soligo, C.; Weisbecker, V.; Safi, K. (2021)
    Relative brain size has long been considered a reflection of cognitive capacities and has played a fundamental role in developing core theories in the life sciences. Yet, the notion that relative brain size validly represents ...
  • Five well-supported fossil calibrations within the "Waterbird" assemblage (Tetrapoda, Aves) 
    Smith, Nathan D.; Ksepka, Daniel T. (2015)
    Five well-supported fossil calibrations within the "Waterbird" assemblage (Tetrapoda, Aves)
  • The Fossil Calibration Database, A New Resource for Divergence Dating 
    Ksepka, Daniel T.; Parham, James F.; Allman, James F.; Benton, Michael J.; Carrano, Matthew T.; Cranston, Karen A.; Donoghue, Philip C. J.; Head, Jason J.; Hermsen, Elizabeth J.; Irmis, Randall B.; Joyce, Walter G.; Kohli, Manpreet; Lamm, Kristin S.; Leehr, Dan; Patané, José S. L.; Polly, P. David; Phillips, Matthew J.; Smith, N. Adam; Smith, Nathan D.; van Tuinen, Marcel; Ware, Jessica L.; Warnock, Rachel C. M. (2015)
    Fossils provide the principal basis for temporal calibrations, which are critical to the accuracy of divergence dating analyses. Translating fossil data into minimum and maximum bounds for calibrations is the most important, ...
  • A history of shifting fortunes for African penguins 
    Thomas, Daniel B.; Ksepka, Daniel T. (2013)
    Africa is home today to only a single breeding species of penguin, Spheniscus demersus (black-footed penguin), which is endangered with extinction. Spheniscus demersus has been the only breeding species of penguin to share ...
  • New pelomedusoid turtles from the late Palaeocene Cerrejón Formation of Colombia and their implications for phylogeny and body size evolution 
    Cadena, Edwin A.; Ksepka, Daniel T.; Jaramillo, Carlos A.; Bloch, Jonathan I. (2012)
  • Oldest Finch-Beaked Birds Reveal Parallel Ecological Radiations in the Earliest Evolution of Passerines 
    Ksepka, Daniel T.; Grande, Lance; Mayr, Gerald (2019)
    Beak shape plays a key role in avian radiations and is one of the most intensely studied aspects of avian evolution and ecology [1-4]. Perhaps no other group is more closely associated with the study of beak shape than ...
  • A Phylogenomic Supertree of Birds 
    Kimball, Rebecca T.; Oliveros, Carl H.; Wang, Ning; White, Noor D.; Barker, F. Keith; Field, Daniel J.; Ksepka, Daniel T.; Chesser, R. Terry; Moyle, Robert G.; Braun, Michael J.; Brumfield, Robb T.; Faircloth, Brant C.; Smith, Brian Tilston; Braun, Edward L. (2019)
    It has long been appreciated that analyses of genomic data (e.g., whole genome sequencing or sequence capture) have the potential to reveal the tree of life, but it remains challenging to move from sequence data to a clear ...
  • Synthesizing and databasing fossil calibrations: divergence dating and beyond 
    Ksepka, Daniel T.; Benton, Michael J.; Carrano, Matthew T.; Gandolfo, Maria A.; Head, Jason J.; Hermsen, Elizabeth J.; Joyce, Walter G.; Lamm, Kristin S.; Patané, José S. L.; Phillips, Matthew J.; Polly, P. David; Van Tuinen, Marcel; Ware, Jessica L.; Warnock, Rachel C. M.; Parham, James F. (2011)
    Divergence dating studies, which combine temporal data from the fossil record with branch length data from molecular phylogenetic trees, represent a rapidly expanding approach to understanding the history of life. National ...
  • Tempo and Pattern of Avian Brain Size Evolution 
    Ksepka, Daniel T.; Balanoff, Amy M.; Smith, N. Adam; Bever, Gabriel S.; Bhullar, Bhart-Anjan S.; Bourdon, Estelle; Braun, Edward L.; Burleigh, J. Gordon; Clarke, Julia A.; Colbert, Matthew W.; Corfield, Jeremy R.; Degrange, Federico J.; De Pietri, Vanesa L.; Early, Catherine M.; Field, Daniel J.; Gignac, Paul M.; Gold, Maria Eugenia Leone; Kimball, Rebecca T.; Kawabe, Soichiro; Lefebvre, Louis; Marugan-Lobon, Jesus; Mongle, Carrie S.; Morhardt, Ashley; Norell, Mark A.; Ridgely, Ryan C.; Rothman, Ryan S.; Scofield, R. Paul; Tambussi, Claudia P.; Torres, Christopher R.; van Tuinen, Marcel; Walsh, Stig A.; Watanabe, Akinobu; Witmer, Lawrence M.; Wright, Alexandra K.; Zanno, Lindsay E.; Jarvis, Erich D.; Smaers, Jeroen B. (2020)
    Relative brain sizes in birds can rival those of primates, but large-scale patterns and drivers of avian brain evolution remain elusive. Here, we explore the evolution of the fundamental brain-body scaling relationship ...
