    • Convergence in Multispecies Interactions 

      Bittleston, Leonora Sophia; Pierce, Naomi E.; Ellison, Aaron M.; Pringle, Anne (Elsevier BV, 2016)
      The concepts of convergent evolution and community convergence highlight how selective pressures can shape unrelated organisms or communities in similar ways. We propose a related concept, convergent interactions, to ...

    • Detective Work in the West Indies: Integrating Historical and Experimental Approaches to Study Island Lizard Evolution 

      Losos, Jonathan (American Institute of Biological Sciences, 2007)
      Evolutionary biology is a historical science, like astronomy and geology. Understanding how and why evolution has occurred requires synthesizing multiple lines of inquiry. Historical studies, such as those that estimate ...

    • Discovering Communities through Friendship 

      Morrison, Gregory C.; Mahadevan, Lakshminarayanan (Public Library of Science, 2012)
      We introduce a new method for detecting communities of arbitrary size in an undirected weighted network. Our approach is based on tracing the path of closest‐friendship between nodes in the network using the recently ...

    • Heat tolerance predicts the importance of species interaction effects as the climate changes 

      Diamond, Sarah E.; Chick, Lacy; Penick, Clint A.; Nichols, Lauren M.; Cahan, Sara Helms; Dunn, Robert R.; Ellison, Aaron M.; Sanders, Nathan J.; Gotelli, Nicholas J. (Oxford University Press (OUP), 2017)
      Few studies have quantified the relative importance of direct effects of climate change on communities versus indirect effects that are mediated thorough species interactions, and the limited evidence is conflicting. ...

    • Individuality, Stability, and Variability of the Plaque Microbiome 

      Utter, Daniel R.; Mark Welch, Jessica L.; Borisy, Gary G. (Frontiers Media S.A., 2016)
      Dental plaque is a bacterial biofilm composed of a characteristic set of organisms. Relatively little information from cultivation-independent, high-throughput analyses has been published on the temporal dynamics of the ...

    • Intercontinental Community Convergence of Ecology and Morphology in Desert Lizards 

      Melville, Jane; Harmon, Luke J.; Losos, Jonathan (The Royal Society of London, 2006)
      Evolutionary ecologists have long debated the extent to which communities in similar environments but different geographic regions exhibit convergence. On the one hand, if species' adaptations and community structure are ...

    • The Irreversible Loss of a Decomposition Pathway Marks the Single Origin of an Ectomycorrhizal Symbiosis 

      Wolfe, Benjamin E.; Tulloss, Rodham E.; Pringle, Anne E. (Public Library of Science, 2012)
      Microbial symbioses have evolved repeatedly across the tree of life, but the genetic changes underlying transitions to symbiosis are largely unknown, especially for eukaryotic microbial symbionts. We used the genus Amanita, ...

    • Species Richness and Trophic Diversity Increase Decomposition in a Co-Evolved Food Web 

      Baiser, Benjamin H.; Ardeshiri, Roxanne S.; Ellison, Aaron M. (Public Library of Science, 2011)
      Ecological communities show great variation in species richness, composition and food web structure across similar and diverse ecosystems. Knowledge of how this biodiversity relates to ecosystem functioning is important ...
