Both when females from line 137 are choosing (n = 27, P = 0.006) and among all females overall (n = 81, P = 0.018), there is an apparent inverse relationship between winning an aggressive encounter and mating.
Sexually experienced female Japanese quails, Coturnix japonica, that are offered a choice between two conspecific males previously observed engaging in an aggressive encounter prefer to affiliate with the less aggressive male [ 34].
Neural activation in response to an aggressive encounter was also examined across photoperiod.
For male line 134, there is also an indication that winning an aggressive encounter correlates with a greater ability to win mates (n = 81, P = 0.035).
The higher the local density, the more likely an aggressive encounter (figure 2 b).
During an aggressive encounter, the acrorhagi inflate and adhere to the opponent, leaving an acrorhagial peel on the opponent [ 9].
Although the CEGMA analysis revealed that the non-aggressive polyp acrorhagi transcriptome was less complete (99% vs 88%), the difference observed in these transcriptomes may be attributed to acrorhagial tissues being more transcriptionally active during an aggressive encounter.
The functional GO groupings identified transcripts that may be more abundant during acrorhagi inflation and expansion, which occurs during an aggressive encounter.
Any aggressive encounter between mice was immediate cause for terminating the experiment and excluding data from an adult from the analysis.
It is speculated that such initial aggressive behavior serves to establish a dominance hierarchy that, once established, renders further aggressive encounters between individuals unnecessary [51].
However, their mothers risk a lot to mate with extra-pack males; aggressive encounters between packs account for 20% of pup deaths and 12% of adult deaths.
