- Molecular phylogenetic evidence for multiple gains or losses of ant mutualism within the aphid genus ChaitophorusAlexander W Shingleton
Department of Ecology and Evolutionary Biology, Princeton University, Guyot Hall, Princeton, NJ 08544, USA
Mol Phylogenet Evol 26:26-35. 2003..This is the first phylogenetic confirmation that ant tending is an evolutionarily labile trait in aphids...
- Body-size regulation: combining genetics and physiologyAlexander W Shingleton
Guyot Hall, Princeton University, Princeton, New Jersey 08544, USA
Curr Biol 15:R825-7. 2005..New research has revealed that the activity of the insulin-signaling pathway in the prothoracic gland of Drosophila modulates ecdysone release and thereby influences both the duration and rate of larval growth...
- The temporal requirements for insulin signaling during development in DrosophilaAlexander W Shingleton
Ecology and Evolutionary Biology, Princeton University, Princeton, New Jersey, USA
PLoS Biol 3:e289. 2005..We hypothesize that the insulin-signaling pathway controls such diverse effects as total developmental time, total body size and organ size through its effects on the rate of cell growth, and proliferation in different organs...
- The origin of a mutualism: a morphological trait promoting the evolution of ant-aphid mutualismsAlexander W Shingleton
Department of Ecology and Evolutionary Biology, Guyot Hall, Princeton University, Princeton, New Jersey 08544, USA

- Diapause in the pea aphid (Acyrthosiphon pisum) is a slowing but not a cessation of developmentAlexander W Shingleton
Department of Ecology and Evolutionary Biology, Princeton University, Princeton, NJ 08544, USA
BMC Dev Biol 3:7. 2003..We investigated developmental aspects of diapause in sexually-produced embryos of the pea aphid, Acyrthosiphon pisum...
- Developmental origin and evolution of bacteriocytes in the aphid-Buchnera symbiosisChristian Braendle
Department of Ecology and Evolutionary Biology, Princeton University, Princeton, New Jersey, USA
PLoS Biol 1:E21. 2003..The evolutionary transition to a symbiosis in which bacteria and an aphid cell form a functional unit, similar to the origin of plastids, has apparently involved extensive molecular adaptations on the part of the host cell...
- Size-correlated division of labour and spatial distribution of workers in the driver ant, Dorylus molestusChristian Braendle
Department of Zoology, University of Cambridge, Cambridge, UK
Naturwissenschaften 90:277-81. 2003..Finally, large workers were more common in open sections of the trail than in covered sections, which are likely to be less exposed to predators...

Department of Zoology, Michigan State University, 203 Natural Science, East Lansing, MI 48910, USA
Bioessays 29:536-48. 2007..This model serves as the foundation for a research program that will result in a deeper understanding of the relationship between growth and form, a question that has fascinated biologists for centuries...
- Developmental model of static allometry in holometabolous insectsAlexander W Shingleton
Department of Zoology, Michigan State University, East Lansing, MI 48824, USA
Proc Biol Sci 275:1875-85. 2008..By revealing how specific physiological and genetic regulators of size influence allometry, the model serves to identify developmental processes upon which evolution may act to alter scaling relationships...
