    • Climatic Drivers of Hemispheric Asymmetry in Global Patterns of Ant Species Richness 

      Arnan, Xavier; McGlynn, Terrence P.; Bruhl, Carsten A.; Agosti, Donat; Lessard, Jean-Philippe; Anderson, Alan N.; Vascibcekis, Heraldo L.; Laurent, Edward J.; Kaspari, Michael E.; Guenard, Benoit; Janda, Milan; Fitzpatrick, Matthew; Pfeiffer, Martin; Weiser, Michael D.; Philpott, Stacy M.; Gove, Aaron D.; Retana, Javier; Suarez, Andrew V.; Dunn, Robert R.; Ellison, Aaron; Cerda, Xim; Parr, Catherine L.; Longino, John T.; Majer, Jonathan D.; Fisher, Brian L.; Manke, Sean B.; Sanders, Nathan J.; Gotelli, Nicholas J.; Gib, Heloise (Blackwell Science, 2009)
      Although many taxa show a latitudinal gradient in richness, the relationship between latitude and species richness is often asymmetrical between the northern and southern hemispheres. Here we examine the latitudinal pattern ...

    • Common Garden Experiments Reveal Uncommon Responses across Temperatures, Locations, and Species of Ants 

      Pelini, Shannon Lynn; Diamond, Sarah E.; MacLean, Heidi; Ellison, Aaron M.; Gotelli, Nicholas J.; Sanders, Nathan J.; Dunn, Robert R. (Wiley Open Access, 2012-10-12)
      Population changes and shifts in geographic range boundaries induced by climate change have been documented for many insect species. On the basis of such studies, ecological forecasting models predict that, in the absence ...

    • Counting Ants (Hymenoptera: Formicidae): Biodiversity Sampling and Statistical Analysis for Myrmecologists 

      Gotelli, Nicholas J.; Ellison, Aaron M.; Dunn, Robert R.; Sanders, Nathan J. (Austrian Society of Entomofaunistics, 2011)
      Biodiversity sampling is labor intensive and is especially challenging for myrmecologists, because the sampling units (individual workers) do not correspond in a simple way to the natural units of diversity (individual ...

    • Effects of Short-Term Warming On Low and High Latitude Forest Ant Communities 

      Pelini, Shannon Lynn; Boudreau, Mark; McCoy, Neil; Ellison, Aaron M.; Gotelli, Nicholas J.; Sanders, Nathan J.; Dunn, Robert R. (Ecological Society of America, 2011)
      Climatic change is expected to have differential effects on ecological communities in different geographic areas. However, few studies have experimentally demonstrated the effects of warming on communities simultaneously ...

    • Global Diversity in Light of Climate Change: the Case of Ants 

      Jenkins, Clinton N.; Sanders, Nathan J.; Andersen, Alan N.; Arnan, Xavier; Brühl, Carsten A.; Cerda, Xim; Ellison, Aaron M.; Fisher, Brian L.; Fitzpatrick, Matthew C.; Gotelli, Nicholas J.; Gove, Aaron D.; Guénard, Benoit; Lattke, John E.; Lessard, Jean-Philippe; McGlynn, Terrence P.; Menke, Sean B.; Parr, Catherine L.; Philpott, Stacy M.; Vasconcelos, Heraldo L.; Weiser, Michael D.; Dunn, Robert R. (Wiley-Blackwell, 2011)
      Aim: To use a fine-grained global model of ant diversity to identify the limits of our knowledge of diversity in the context of climate change. Location: Global. Methods: We applied generalized linear modelling to a ...

    • 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. ...

    • Heating Up the Forest: Open-Top Chamber Warming Manipulation of Arthropod Communities at Harvard and Duke Forests 

      Pelini, Shannon Lynn; Bowles, Francis P.; Ellison, Aaron M.; Gotelli, Nicholas J.; Sanders, Nathan J.; Dunn, Robert R. (John Wiley & Sons, 2011)
      1. Recent observations indicate that climatic change is altering biodiversity, and models suggest that the consequences of climate change will differ across latitude. However, long-term experimental field manipulations ...

    • A Physiological Trait-Based Approach To Predicting The Responses Of Species To Experimental Climatic Warming 

      Diamond, Sarah E.; Nichols, Lauren M.; McCoy, Neil; Hirsch, Christopher; Pelini, Shannon Lynn; Sanders, Nathan J.; Ellison, Aaron M.; Gotelli, Nicholas J.; Dunn, Robert R. (Ecological Society of America, 2012)
      Physiological tolerance of environmental conditions can influence species-level responses to climatic change. Here, we used species-specific thermal tolerances to predict the community responses of ant species to experimental ...

    • Thermal reactionomes reveal divergent responses to thermal extremes in warm and cool-climate ant species 

      Stanton-Geddes, John; Nguyen, Andrew; Chick, Lacy; Vincent, James; Vangala, Mahesh; Dunn, Robert R.; Ellison, Aaron M.; Sanders, Nathan J.; Gotelli, Nicholas J.; Cahan, Sara Helms (Springer Science + Business Media, 2016)
      Background: The distributions of species and their responses to climate change are in part determined by their thermal tolerances. However, little is known about how thermal tolerance evolves. To test whether evolutionary ...

    • Using Historical and Experimental Data to Reveal Warming Effects on Ant Assemblages 

      Resasco, Julian; Pelini, Shannon L.; Stuble, Katharine L.; Sanders, Nathan J.; Dunn, Robert R.; Diamond, Sarah E.; Ellison, Aaron M.; Gotelli, Nicholas J.; Levey, Douglas J. (Public Library of Science (PLoS), 2014)
      Historical records of species are compared with current records to elucidate effects of recent climate change. However, confounding variables such as succession, land-use change, and species invasions make it difficult to ...
