Evolution of Novel Mosaic Castes in Ants: Modularity, Phenotypic Plasticity, and Colonial Buffering by Molet, Mathieu, Wheeler, Diana E., Peeters, Christian

“…Many ants have independently evolved castes with novel morphology as well as function, such as soldiers and permanently wingless (ergatoid) queens. We present…”

Independent colony foundation in Paraponera clavata (Hymenoptera, Formicidae): First workers lay trophic eggs to feed queen’s larvae by Peeters, Christian

“…Paraponera clavata Smith is a large, notorious, and widely distributed ant, yet its colony founding behavior is poorly known. In the laboratory, a dealate…”

The loss of flight in ant workers enabled an evolutionary redesign of the thorax for ground labour by Peeters, Christian, Keller, Roberto A, Khalife, Adam, Fischer, Georg, Katzke, Julian, Blanke, Alexander, Economo, Evan P

“…Explanations for the ecological dominance of ants generally focus on the benefits of division of labour and cooperation during foraging. However, the principal…”

Bigger helpers in the ant Cataglyphis bombycina: increased worker polymorphism or novel soldier caste? by Molet, Mathieu, Maicher, Vincent, Peeters, Christian

“…The mechanisms by which development favors or constrains the evolution of new phenotypes are incompletely understood. Polyphenic species may benefit from…”

Skeletomuscular adaptations of head and legs of Melissotarsus ants for tunnelling through living wood by Khalife, Adam, Keller, Roberto A, Billen, Johan, Hita Garcia, Francisco, Economo, Evan P, Peeters, Christian

“…While thousands of ant species are arboreal, very few are able to chew and tunnel through living wood. Ants of the genus (subfamily Myrmicinae) inhabit tunnel…”

Evolution of thorax architecture in ant castes highlights trade-off between flight and ground behaviors by Keller, Roberto A, Peeters, Christian, Beldade, Patrícia

“…The concerted evolution of morphological and behavioral specializations has compelling examples in ant castes. Unique to ants is a marked divergence between…”

Cuticular Hydrocarbons Mediate Discrimination of Reproductives and Nonreproductives in the Ant Myrmecia gulosa by Dietemann, Vincent, Peeters, Christian, Liebig, Jürgen, Thivet, Virginie, Hölldobler, Bert

“…In many species of social insects, the cuticular hydrocarbons of adults vary with both colony identity and individual physiology (oogenesis). Such variations…”

A mutualism without honeydew: what benefits for Melissotarsus emeryi ants and armored scale insects (Diaspididae)? by Peeters, Christian, Foldi, Imre, Matile-Ferrero, Danièle, Fisher, Brian L

“…Mutualisms between ants and sap-sucking insects generally involve clear benefits for both partners: the ants provide protection in exchange for honeydew…”

Selection against aerial dispersal in ants: two non-flying queen phenotypes in Pogonomyrmex laticeps by Peeters, Christian, Keller, Roberto A, Johnson, Robert A

“…The South American seed-harvester ant Pogonomyrmex laticeps has dimorphic queens: ergatoid (permanently wingless) and brachypterous (short, non-functional…”

Are Variations in Cuticular Hydrocarbons of Queens and Workers a Reliable Signal of Fertility in the Ant Harpegnathos saltator? by Liebig, Jurgen, Peeters, Christian, Oldham, Neil J., Markstadter, Claus, Holldobler, Bert

“…One of the key features of insect societies is the division of labor in reproduction between one or a few fertile individuals and many sterile nestmates that…”

Both female castes contribute to colony emigration in the polygynous ant Mystrium oberthueri by BOUCHET, DIANE C., PEETERS, CHRISTIAN, FISHER, BRIAN L., MOLET, MATHIEU
