We carried out four experiments, the first of which was designed to confirm the reproductive mode, then, to investigate the copulating capacity of male adult together with to evaluate influence of the female age and density on male copulating capacity, and finally to investigate the influence of copulation
on female longevity.
In the case of the particular female in which laboratory copulation
was observed, six capsules were released on the first day after copulation
, 11 on the second day, 20 on the third, 18 on the fourth, and 23 on the fifth day (n = 78 in total).
ratio of the MNP group was lower than that of the MC, MSh, and MNP+TR groups (44.44%, 100%, 100%, and 85.71%, respectively; p<0.05).
23 (60.5%) resulted in copulations
. Among those that did not result in copulations
, only four were because males did not attempt copulation
and one was because the female cannibalized the male.
We included in our analysis only the encounters that resulted in copulation
(n = 15 of 22).
In addition to increasing predation risk, copulation
has energetic costs.
Seven females were maintained in nest sites that permitted visual, auditory, and tactile contact with their paired male but not copulation
for 18.3 [+ or -] 2.4 days before egg lay.
Specifically, this book traverses the centuries of scientific research gathered on our pursuit of copulation
, self-dosing in order to trigger the release of biochemicals, and making loud noises in the form of rock music.
(2013), we conclude that the use of multiple couples at least doubled the number of copulation
"They rolled together into the one giggling snowball of full-figured copulation
" - Extract from Morrissey's novel which won him the bad sex award.
Little do they know, Laura is an earthbound extraterrestrial who sheds her skin during copulation

He was moving his rear end rhythmically, suggesting that copulation

So thankfully, a company has seen sense and decided to pull a show bereft of any originality and filled with commercial copulation
This is a pair bon<4, then, instead of a situation of forced copulation
