    • Geographic Variation in Network Structure of a Nearctic Aquatic Food Web 

      Baiser, Benjamin H.; Gotelli, Nicholas J.; Buckley, Hannah L.; Miller, Thomas E.; Ellison, Aaron M. (Blackwell Publishing Ltd, 2011)
      Aim: The network structure of food webs plays an important role in the maintenance of diversity and ecosystem functioning in ecological communities. Previous research has found that ecosystem size, resource availability, ...
    • Modeling foundation species in food webs 

      Baiser, Benjamin; Whitaker, Nathaniel; Ellison, Aaron M. (Ecological Society of America, 2013)
      Foundation species are basal species that play an important role in determining community composition by physically structuring ecosystems and modulating ecosystem processes. Foundation species largely operate via non-trophic ...
    • Organic-Matter Loading Determines Regime Shifts and Alternative States in an Aquatic Ecosystem 

      Sirota, Jennie; Baiser, Benjamin; Gotelli, Nicholas J.; Ellison, Aaron M. (Proceedings of the National Academy of Sciences, 2013)
      Slow changes in underlying state variables can lead to “tipping points,” rapid transitions between alternative states (“regime shifts”) in a wide range of complex systems. Tipping points and regime shifts routinely are ...
    • Predicting Food-Web Structure With Metacommunity Models 

      Baiser, Benjamin H.; Buckley, Hannah L.; Gotelli, Nicholas; Ellison, Aaron M. (Nordic Ecological Society, 2012)
      The metacommunity framework explores the relative influence of local and regional-scale processes in generating diversity patterns across the landscape. Metacommunity models and empirical studies have focused mostly on ...
    • Response of Macroarthropod Assemblages to the Loss of Hemlock (Tsuga canadensis), a Foundation Species 

      Sackett, Tara E.; Record, Sydne; Bewick, Sharon; Baiser, Benjamin H.; Sanders, Nathan J.; Ellison, Aaron M. (Ecological Society of America, 2011)
      In eastern North American forests, eastern hemlock (Tsuga canadensis) is a foundation species. As hemlock is lost from forests due to the invasive hemlock woolly adelgid (Adelges tsugae) and pre-emptive salvage logging, ...
    • 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 ...
