MATING FREQUENCY AND FECUNDITY IN INSECTS
1. The paper summarizes the published evidence on the relation between mating frequency and fecundity in insects. There is experimental evidence of varying quality for 63 species and non‐experimentalExpand
A model of mate guarding
TLDR
A mathematical model confirms that precopula will evolve when mating is restricted in time, and specifies the evolutionary stable duration of precipula. Expand
The explanation of organic diversity : the comparative method and adaptations for mating
TLDR
This book attempts to show how the comparative method can be improved if only independent trials of evolutionary hypotheses are counted, and applies these methods to two questions about sexual behaviour: precopulatory mate guarding, and homogamy of size. Expand
The number of males in a primate troop

  • Animal Behaviour
  • 1 December 1986
TLDR
Primate species in which the breeding group contains more than one adult female may typically live in ‘harems’, with one male, or multi-male troops, that that variable is associated with the duration of the breeding season is shown. Expand
The cladistic solution to the species problem
TLDR
The correct explanation of why species, in evolutionary theory, are individuals and not classes is the cladistic species concept, which has the virtue of distinguishing clearly the theoretical nature of species from the practical criteria by which species may be recognized at any one time. Expand
Paternal care
This review presents a systematic compilation of species in which only the male cares for the offspring. Such species occur rarely in the polychaetes, Hemiptera, Amphibia and birds and more often inExpand
Brief communication: pelvic sexual dimorphism and relative neonatal brain size really are related.
  • M. Ridley
  • Biology, Medicine
  • American journal of physical anthropology
  • 1 June 1995
TLDR
Primate species in which the neonatal brain size is large relative to the birth canal tend to have more sexually dimorphic pelves: this is a classic comparative relation discovered by Schultz and Leutenegger and retested, correcting for all four statistical defects. Expand
