Caste allocation in litter Pheidole: lessons from plant defense theory

  title={Caste allocation in litter Pheidole: lessons from plant defense theory},
  author={Michael Kaspari and Margaret Mary Byrne},
  journal={Behavioral Ecology and Sociobiology},
The allocation to growth, defense and reproduction varies in social insects within a species' life cycle and between species. A life cycle model (Oster and Wilson 1978) generally failed to predict caste allocation in small litter-nesting colonies of Neotropical Pheidole. Two of its assumptions were often invalid: food was unlikely to be limiting in four of five populations, and sexual biomass production accelerated, not decelerated, with colony size in three of five populations. One of five… CONTINUE READING
