The Evolution of Mating Systems in Insects and Arachnids
If the advantages of controlling paternity are equal across mating systems, then
the prevalence of postcopulatory female choice should be predictable from the
costs and benefits of different forms and stages of mate choice. Postcopulatory ...

Sperm Competition and the Evolution of Animal Mating systems
This section presents an overview of odonate postcopulatory behavior and
explores the link between it and sperm competition. There are two possible
approaches: assume sperm displacement is universal among odonates and ask
how ...
Postcopulatory Sexual Selection Notwithstanding his deep appreciation for
precopulatory sexual selection including mate competition and mate choice,
Darwin did not comment on the potential for postcopulatory sexual selection, or
selection ...

Mating Systems and Strategies
Multiple mating by females with capacities for sperm storage opens several new
avenues for sexual selection: (a) postcopulatory, prezygotic reproductive
competition between males (Robinson et al. 1994; Ketterson et al. 1997; Travis et
al.

Evolutionary Behavioral Ecology
When some males are excluded from the postcopulatory arena by precopulatory
events, and males that are most attractive in the precopulatory arena also have
greatest postcopulatory success, variance in reproductive success may be ...

In the Light of Evolution:: Volume III: Two Centuries of Darwin
There are postcopulatory equivalents inside the female of Darwin's precopulatory
male-male struggles and female choice (Table 12.1). if a female copulates with >
1 male, and if one of these males is better than others at, for instance, removing ...
