- Paleodistributions and comparative molecular phylogeography of leafcutter ants (Atta spp.) provide new insight into the origins of Amazonian diversityScott E Solomon
Section of Integrative Biology, University of Texas at Austin, Austin, Texas, USA
PLoS ONE 3:e2738. 2008..Our results also reconceptualize the traditional Pleistocene refugia hypothesis, and offer a novel framework for future research into the area...
- Frontier mutualism: coevolutionary patterns at the northern range limit of the leaf-cutter ant-fungus symbiosisUlrich G Mueller
Section of Integrative Biology, University of Texas at Austin, Austin, TX 78712, USA
Proc Biol Sci 278:3050-9. 2011..Studies of such populations are most likely to inform models of coextinctions of obligate mutualistic partners that are doubly stressed by habitat marginality and by environmental change...
- Evolution of cold-tolerant fungal symbionts permits winter fungiculture by leafcutter ants at the northern frontier of a tropical ant-fungus symbiosisUlrich G Mueller
Section of Integrative Biology, University of Texas, Austin, TX 78712, USA
Proc Natl Acad Sci U S A 108:4053-6. 2011..Evolution of cold-tolerant fungi within the symbiosis relaxed constraints on winter fungiculture at the northern frontier of the leafcutter ant distribution, thereby expanding the ecological niche of an obligate host-microbe symbiosis...
