    • The 10kTrees Website: A New Online Resource for Primate Phylogeny 

      Arnold, Christian; Matthews, Luke J.; Nunn, Charles Lindsay (John Wiley & Sons, 2010)
      The comparative method plays a central role in efforts to uncover the adaptive basis for primate behaviors, morphological traits, and cognitive abilities.[1-4] The comparative method has been used, for example, to infer ...

    • Comparative Chewing Efficiency in Mammalian Herbivores 

      Fritz, Julia; Hummel, Jürgen; Kienzle, Ellen; Arnold, Christian; Nunn, Charles Lindsay; Clauss, Marcus (Nordic Ecological Society, 2009)
      Although the relevance of particle size reduction in herbivore digestion is widely appreciated, few studies have investigated digesta particle size across species in relation to body mass or digestive strategy. We investigated ...

    • Mutualism or Parasitism? Using a Phylogenetic Approach to Characterize the Oxpecker-Ungulate Relationship 

      Nunn, Charles Lindsay; Ezenwa, Vanessa O.; Arnold, Christian; Koenig, Walter D. (Wiley-Blackwell, 2011)
      With their striking predilection for perching on African ungulates and eating their ticks, yellow-billed (Buphagus africanus) and red-billed oxpeckers (B. erythrorhynchus) represent one of the few potentially mutualistic ...

    • Phylogenetic Targeting of Research Effort in Evolutionary Biology 

      Arnold, Christian; Nunn, Charles Lindsay (University of Chicago Press, 2010)
      Many questions in comparative biology require that new data be collected, either to build a comparative database for the first time or to augment existing data. Given resource limitations in collecting data, the question ...

    • Polynomial Algorithms for the Maximal Pairing Problem: Efficient Phylogenetic Targeting on Arbitrary Trees 

      Arnold, Christian; Stadler, Peter F (BioMed Central, 2010)
      Background: The Maximal Pairing Problem (MPP) is the prototype of a class of combinatorial optimization problems that are of considerable interest in bioinformatics: Given an arbitrary phylogenetic tree T and weights ωxy ...

    • Primate Extinction Risk and Historical Patterns of Speciation and Extinction in Relation to Body Mass 

      Matthews, Luke J.; Arnold, Christian; Machanda, Zarin Pearl; Nunn, Charles Lindsay (Royal Society of London, 2011)
      Body mass is thought to influence diversification rates, but previous studies have produced ambiguous results. We investigated patterns of diversification across 100 trees obtained from a new Bayesian inference of primate ...

    • Simulating Trait Evolution for Cross-Cultural Comparison 

      Nunn, Charles Lindsay; Arnold, Christian; Matthews, Luke; Borgerhoff Mulder, Monique (The Royal Society, 2010)
      Cross-cultural anthropologists have increasingly used phylogenetic methods to study cultural variation. Because cultural behaviors can be transmitted horizontally among socially defined groups, however, it is important ...
