Yet, leading hypotheses regarding the ancestral habitat of ants conflict with new findings that early ant lineages are cryptic and subterranean. Where the ants evolved, in respect to habitat, and how habitat shifts took place over time have not been formally tested. Here, we reconstruct the habitat transitions of crown-group ants through time, focusing on where they nest and forage (in the canopy, litter, or soil). Based on ancestral character reconstructions, we show that in contrast to the current consensus based on verbal arguments that ants evolved in tropical leaf litter, the soil is supported as the ancestral stratum of all ants. We also find subsequent movements up into the litter and, in some cases, into the canopy. Given the global importance of ants, because of their diversity, ecological influence and status as the most successful eusocial lineage on Earth, understanding the early evolution of this lineage provides insight into the factors that made this group so successful today.}, number={12}, journal={PLOS ONE}, author={Lucky, Andrea and Trautwein, Michelle D. and Guenard, Benoit S. and Weiser, Michael D. and Dunn, Robert R.}, year={2013}, month={Dec} } @article{guenard_dunn_2012, title={A checklist of the ants of China}, number={3558}, journal={Zootaxa}, author={Guenard, B. and Dunn, R.

Global models of species diversity rarely focus on insects and none attempt to address unknown, undescribed diversity. We assembled a database representing about 13,000 records for ant generic distribution from over 350 regions that cover much of the globe. Based on two models of diversity and endemicity, we identified regions where our knowledge of ant diversity is most limited, regions we have called “hotspots of discovery.” A priori, such regions might be expected to be remote and untouched. Instead, we found that the hotspots of discovery are also the regions in which biodiversity is the most threatened by habitat destruction. Our results not only highlight the immediate need for conservation of the remaining natural habitats in these regions, but also the extent to which, by focusing on well-known groups such as vertebrates, we may fail to conserve the far greater diversity of the smaller species yet to be found.}, number={19}, journal={PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA}, author={Guenard, Benoit and Weiser, Michael D. and Dunn, Robert R.}, year={2012}, month={May}, pages={7368–7373} } @article{jenkins_sanders_andersen_arnan_bruehl_cerda_ellison_fisher_fitzpatrick_gotelli_et al._2011, title={Global diversity in light of climate change: the case of ants}, volume={17}, ISSN={["1472-4642"]}, url={http://www.scopus.com/inward/record.url?eid=2-s2.0-79958088243&partnerID=MN8TOARS}, DOI={10.1111/j.1472-4642.2011.00770.x}, abstractNote={Abstract}, number={4}, journal={DIVERSITY AND DISTRIBUTIONS}, author={Jenkins, Clinton N. and Sanders, Nathan J. and Andersen, Alan N. and Arnan, Xavier and Bruehl, Carsten A. and Cerda, Xim and Ellison, Aaron M. and Fisher, Brian L. and Fitzpatrick, Matthew C. and Gotelli, Nicholas J. and et al.}, year={2011}, month={Jul}, pages={652–662} } @article{roura-pascual_hui_ikeda_leday_richardson_carpintero_espadaler_gomez_guenard_hartley_et al._2011, title={Relative roles of climatic suitability and anthropogenic influence in determining the pattern of spread in a global invader}, volume={108}, number={1}, journal={Proceedings of the National Academy of Sciences of the United States of America}, author={Roura-Pascual, N. and Hui, C. and Ikeda, T. and Leday, G. and Richardson, D.

In ants, four main types of foraging strategies are typically recognized based on the intensity of recruitment and the importance of chemical communication. Here, we describe a new type of foraging strategy, "tandem carrying", which is also one of the most simple recruitment strategies, observed in the Ponerinae species Pachycondyla chinensis. Within this strategy, workers are directly carried individually and then released on the food resource by a successful scout. We demonstrate that this recruitment is context dependent and based on the type of food discovered and can be quickly adjusted as food quality changes. We did not detect trail marking by tandem-carrying workers. We conclude by discussing the importance of tandem carrying in an evolutionary context relative to other modes of recruitment in foraging and nest emigration.}, number={8}, journal={Naturwissenschaften (Berlin, Germany)}, author={Guenard, B. and Silverman, J.}, year={2011}, pages={651–659} } @article{menke_guenard_sexton_weiser_dunn_silverman_2011, title={Urban areas may serve as habitat and corridors for dry-adapted, heat tolerant species; an example from ants}, volume={14}, ISSN={["1573-1642"]}, url={http://www.scopus.com/inward/record.url?eid=2-s2.0-79955054212&partnerID=MN8TOARS}, DOI={10.1007/s11252-010-0150-7}, number={2}, journal={URBAN ECOSYSTEMS}, author={Menke, Sean B. and Guenard, Benoit and Sexton, Joseph O. and Weiser, Michael D. and Dunn, Robert R. and Silverman, Jules}, year={2011}, month={Jun}, pages={135–163} } @article{guenard_lucky_2011, title={shuffling leaf litter samples produces more accurate and precise snapshots of terrestrial arthropod community composition}, volume={40}, number={6}, journal={Environmental Entomology}, author={Guenard, B. and Lucky, A.}, year={2011}, pages={1523–1529} } @article{guenard_dunn_2010, title={A New (Old), Invasive Ant in the Hardwood Forests of Eastern North America and Its Potentially Widespread Impacts}, volume={5}, ISSN={["1932-6203"]}, url={http://www.scopus.com/inward/record.url?eid=2-s2.0-77955370644&partnerID=MN8TOARS}, DOI={10.1371/journal.pone.0011614}, abstractNote={Biological invasions represent a serious threat for the conservation of biodiversity in many ecosystems. While many social insect species and in particular ant species have been introduced outside their native ranges, few species have been successful at invading temperate forests. In this study, we document for the first time the relationship between the abundance of the introduced ant, Pachycondyla chinensis, in mature forests of North Carolina and the composition, abundance and diversity of native ant species using both a matched pair approach and generalized linear models. Where present, P. chinensis was more abundant than all native species combined. The diversity and abundance of native ants in general and many individual species were negatively associated with the presence and abundance of P. chinensis. These patterns held regardless of our statistical approach and across spatial scales. Interestingly, while the majority of ant species was strongly and negatively correlated with the abundance and presence of P. chinensis, a small subset of ant species larger than P. chinensis was either as abundant or even more abundant in invaded than in uninvaded sites. The large geographic range of this ant species combined with its apparent impact on native species make it likely to have cascading consequences on eastern forests in years to come, effects mediated by the specifics of its life history which is very different from those of other invasive ants. The apparent ecological impacts of P. chinensis are in addition to public health concerns associated with this species due to its sometimes, deadly sting.}, number={7}, journal={PLOS ONE}, author={Guenard, Benoit and Dunn, Robert R.}, year={2010}, month={Jul} } @article{weiser_sanders_agosti_andersen_ellison_fisher_gibb_gotelli_gove_gross_et al._2010, title={Canopy and litter ant assemblages share similar climate-species density relationships}, volume={6}, ISSN={["1744-9561"]}, url={http://www.scopus.com/inward/record.url?eid=2-s2.0-78649884769&partnerID=MN8TOARS}, DOI={10.1098/rsbl.2010.0151}, abstractNote={Tropical forest canopies house most of the globe's diversity, yet little is known about global patterns and drivers of canopy diversity.

Ant species density is positively associated with temperature and precipitation, and negatively (or non-significantly) associated with two metrics of seasonality, precipitation seasonality and temperature range. Ant species density was significantly higher in canopy samples, but this difference disappeared once abundance was considered. Thus, apparent differences in species density between canopy and litter samples are probably owing to differences in abundance–diversity relationships, and not differences in climate–diversity relationships.
