Twenty-one other copulations
by 11 pairs were observed from 1999-2009 during routine flock monitoring.
These animals are "simultaneous hermaphrodites," meaning each performs both the "male role" of donating sperm to a mating partner and the "female role" of receiving sperm from the partner simultaneously during copulation
Mechanisms that operate before copulation
may lead to traits such as weaponry, dimorphism in size, increased ability to find a receptive female, increased endurance, conspicuous ornaments, and behavioral signals (Andersson, 1994).
The frequency of copulation
also varies among families and species.
When first copulations
were initiated, they lasted from 1.
If the brief copulations
with surviving males are not sufficient to allow sperm transfer, what appears to be post-mating cannibalism will be classified more appropriately as pre-mating cannibalism.
agrestis we created a hypothesis framework, and tested it in single mating experiments where the copulations
were interrupted to ensure predefined duration.
lasted nearly 2 min, and during penetration, the male performed intense leg tapping on the dorsum of the female using his first pair of legs, and simultaneously on the female's hind legs and venter using his second pair of legs.
This hypothesis predicts males should remain close to females during the times when copulations
are more likely to occur (Birkhead and Moller 1992).
these males are known to sever their own genitals in an attempt to plug the female, thereby gaining paternity advantage by preventing other males from mating with her.
The objectives of our study were to (1) assess the roles of behavioral, territorial, and morphological characteristics for Lesser Prairie-Chicken mate choice, (2) report dates of peak female attendance and copulations
, and (3) assess the extent of mating skew on prairie-chicken leks.
During acclimation, we observed males attempting copulations
with other males.
