Surface hydrocarbons of queen eggs regulate worker reproduction in a social insect.
A hitherto largely unresolved problem in behavioral biology is how workers are prevented from reproducing in large insect societies with high relatedness. Signals of the queen are assumed to informExpand
Herbivory of Leaf-Cutting Ants: A Case Study on Atta colombica in the Tropical Rainforest of Panama
1 About This Book.- 2 The Natural History of Leaf-Cutting Ants.- 3 The Study Area - Barro Colorado Island.- 4 Species Composition of the Forest.- 5 Forest Light Regimes.- 6 Canopy Structure of theExpand
Eusociality: origin and consequences.
In this new assessment of the empirical evidence, an alternative to the standard model is proposed: group selection is the strong binding force in eusocial evolution; individual selection, the strongExpand
The genome sequence of Blochmannia floridanus: Comparative analysis of reduced genomes
Bacterial symbioses are widespread among insects, probably being one of the key factors of their evolutionary success. We present the complete genome sequence of Blochmannia floridanus, the primaryExpand
The number of queens: An important trait in ant evolution
The pervasive social and ecological differences between ant colonies that have a single queen and those that have multiple queens are defined. The evolutionary tendencies which lead to polygyny andExpand
Territorial strategies in ants.
Several features in social insects, particularly in ants, make the behavioral organization of territoriality considerably more complex than that of solitary animals. The establishment and maintenanceExpand
Are variations in cuticular hydrocarbons of queens and workers a reliable signal of fertility in the ant Harpegnathos saltator?
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 function as helpers. The behavioral andExpand
Recruitment behavior, home range orientation and territoriality in harvester ants, Pogonomyrmex
Summary1.Scouts of the harvester ant Pogonomyrmex barbatus, P. maricopa and P. rugosus which discovered a new rich foraging area recruit nestmates by laying a trail with poison gland contents fromExpand
Morphologic representation of visual and antennal information in the ant brain
Ants in general are primarily olfactory animals, but many species also express visual behaviors. We analyze in 14 species, which range from purely olfactory to predominantly visually behaving ants,Expand
The rise of the ants: a phylogenetic and ecological explanation.
In the past two decades, studies of anatomy, behavior, and, most recently, DNA sequences have clarified the phylogeny of the ants at the subfamily and generic levels. In addition, a rich new harvestExpand
