    • Asexual reproduction in introduced and native populations of the antCerapachys biroi 

      Kronauer, Daniel J. C.; Pierce, Naomi Ellen; Keller, Laurent (Wiley-Blackwell, 2012)
      Asexual reproduction is particularly common among introduced species, probably because it helps to overcome the negative effects associated with low population densities during colonization. The ant Cerapachys biroi has ...
    • Bacterial gut symbionts are tightly linked with the evolution of herbivory in ants 

      Russell, J. A.; Moreau, C. S.; Goldman-Huertas, B.; Fujiwara, M.; Lohman, David J.; Pierce, Naomi E. (Proceedings of the National Academy of Sciences, 2009)
      Ants are a dominant feature of terrestrial ecosystems, yet we know little about the forces that drive their evolution. Recent findings illustrate that their diets range from herbivorous to predaceous, with “herbivores” ...
    • Canopy and Litter Ant Assemblages Share Similar Climate-Species Density Relations 

      Weiser, Michael; Sanders, Nathan J.; Agosti, Donat; Anderson, Alan N.; Ellison, Aaron M.; Fisher, Brian L.; Gibb, Heloise; Gotelli, Nicholas; Gove, Aaron; Gross, Kevin; Janda, Milan; Kaspari, Michael; Lessard, Jean-Phillippe; Longino, John T.; Majer, Jonathan; Menke, Sean; Terrence, McGlynn; Parr, Catherine; Philpott, Stacy; Retana, Javier; Suarez, Andrew; Vasconcelos, Heraldo; Yanoviak, Stephen; Dunn, Robert; Guénard, Benoit (Royal Society, 2010)
      Tropical forest canopies house most of the globe’s diversity, yet little is known about global patterns and drivers of canopy diversity. Here we present models of ant species density, using climate, abundance and habitat ...
    • Changes in canopy structure and ant assemblages affect soil ecosystem variables as a foundation species declines 

      Kendrick, J.A.; Ribbons, R.R.; Classen, A.T.; Ellison, Aaron M. (Ecological Society of America, 2015)
      The decline of Tsuga canadensis (eastern hemlock) – a foundation tree species – due to infestation by Adelges tsugae (hemlock woolly adelgid) or its complete removal from a stand by salvage logging dramatically affects ...
    • 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 ...
    • Detection probabilities for sessile organisms 

      Berberich, Gabriele M.; Dormann, Carsten F.; Klimetzek, Dietrich; Berberich, Martin B.; Sanders, Nathan J.; Ellison, Aaron M. (Wiley-Blackwell, 2016)
      Estimation of population sizes and species ranges are central to population and conservation biology. It is widely appreciated that imperfect detection of mobile animals must be accounted for when estimating population ...
    • 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 ...
    • The first record of Laboulbeniales (Fungi, Ascomycota) on Ants (Hymenoptera, Formicidae) in The Netherlands 

      Haelewaters, Danny (Ascomycete.org, 2012)
      Laboulbeniales (Fungi, Ascomycetes) are obligate ectoparasites of arthropods, mostly true insects. 80% of all Laboulbeniales parasitize beetles, 10% flies. Also other groups of insects are known to support Laboulbeniales ...
    • 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 ...
    • 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 ...
    • Nine novel microsatellite markers for the army ant Simopelta pergandei (subfamily Ponerinae) 

      Kronauer, Daniel J. C.; Boomsma, Jacobus J.; Pierce, Naomi E. (Springer Nature, 2010)
      Simopelta (subfamily Ponerinae) army ants are specialized predators of other ants in New World tropical forests. Although they show a striking convergence in overall life-history with the well known army ants of the ...
    • 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 ...
    • 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, ...
    • Strict monandry in the ponerine army ant genus Simopelta suggests that colony size and complexity drive mating system evolution in social insects 

      Kronauer, Daniel J. C.; O'Donnell, Sean; Boomsma, Jacobus J.; Pierce, Naomi E. (Wiley-Blackwell, 2010)
      Altruism in social insects has evolved between closely related full-siblings. It is therefore of considerable interest why some groups have secondarily evolved low within-colony relatedness, which in turn affects the ...
    • Studies of Laboulbeniales (Fungi, Ascomycota) on Myrmica ants: Rickia wasmannii in the Netherlands 

      Haelewaters, Danny; Boer, Peter; Noordijk, Jinze (Pensoft Publishers, 2015)
      An important group of fungal insect parasites is the Laboulbeniales (Ascomycota). These are microscopic in size and live attached to the cuticle of their arthropod hosts. Rickia wasmannii is a common European species limited ...
