Molecular ecology of social behaviour: analyses of breeding systems and genetic structure
  • K. Ross
  • Biology, Medicine
  • Molecular ecology
  • 1 February 2001
TLDR
A conceptual and mathematical framework that links attributes of the breeding system to group composition and genetic structure is presented here, and recent empirical studies are reviewed in the context of this framework. Expand
Global Invasion History of the Fire Ant Solenopsis invicta
TLDR
An assessment of genetic variation at a diverse set of molecular markers in 2144 fire ant colonies from 75 geographic sites worldwide revealed that at least nine separate introductions of S. invicta have occurred into newly invaded areas and that the main southern U.S. population is probably the source of all but one of these introductions. Expand
Identification of a Major Gene Regulating Complex Social Behavior
TLDR
It is shown that single genes of major effect can underlie the expression of complex behaviors important in social evolution, and regulation of social organization by Gp-9 is conserved in South American fire ant species exhibiting social polymorphism. Expand
The Breeding System of the Fire Ant Solenopsis invicta: Effects on Colony Genetic Structure
  • K. Ross
  • Medicine, Biology
  • The American Naturalist
  • 1 April 1993
TLDR
Significant differences within nests in the matrilineal composition of worker and queen brood are revealed, constituting further evidence for inequities among nest-mate queens in the allocation of their progeny to the two castes at a single point in time. Expand
Genetic control of social organization in an ant.
  • K. Ross, L. Keller
  • Biology, Medicine
  • Proceedings of the National Academy of Sciences…
  • 24 November 1998
TLDR
Findings reveal how a single genetic factor can have major effects on complex social behavior and influence the nature of social organization in the fire ant Solenopsis invicta. Expand
Kin selection and the problem of sperm utilization in social insects
  • K. Ross
  • Biology
  • Nature
  • 30 October 1986
TLDR
This first study of long-term sperm utilization in natural populations of highly social insects shows that queens of two social wasp species use sperm from different males in relatively constant proportions through time, resulting in consistently low relatedness among female nestmates. Expand
Multilocus evolution in fire ants: effects of selection, gene flow and recombination.
  • K. Ross
  • Biology, Medicine
  • Genetics
  • 1 April 1997
TLDR
Evidence is presented that selection acting independently on Pgm-3 and Gp-9, in conjunction with gene flow from the alternate, "monogyne" social form of this species, may explain the origin of disequilibrium between the two loci in polygyne fire ants. Expand
Species delimitation: a case study in a problematic ant taxon.
TLDR
This study uses genetic data from 68 markers, combined with distributional, bioclimatic, and coloration information, to hypothesize boundaries of evolutionarily independent lineages (species) within the widespread and highly variable nominal fire ant species Solenopsis saevissima, a member of a species group containing invasive pests as well as species that are models for ecological and evolutionary research. Expand
The Natural Selection of Sexual Cannibalism
TLDR
Phenomena selecting for sexual cannibalism appear more closely related to paternal investment strategies than to ecological factors associated with other forms of cannibalism, and specific field observations are suggested which would provide quantitative estimates of the expected number of male matings.
