Primary intercourse rates try 1:one in C
Bots under the large feeding regimen receive when you look at the solid groups that have a strong regression line, and you may bots according to the reduced feeding routine are offered inside the open circles which have a beneficial dashed regression line.
Of your 80 pairs that courted, 32 (40%) copulated inside 30 min (Fig step 3). Throughout courtship, the feminine techniques the latest courting men until the woman is about step one cm aside.

You will find zero effect of men serving techniques or chronilogical age of often sex toward copulation (GLM male giving: z = step 1.4, p = 0.16; female ages: z = 1.3, p = 0.20; men decades: z = 0.6, p = 0.56; Fig 5).
“F” and you may “M” suggest female and male, respectively, plus the preceding page implies highest “H” otherwise low “L” feeding regimes. Brackets group high and you will low feeding ladies, hence differed in their copulation probability. (more…)
