Authors discuss the possible role of skill in determining mating success; they highlight functional similarities between fighting and mating behaviours

Skilful mating? Insights from animal contest research. Sarah M. Lane, Mark Briffa. Animal Behaviour, Apr 22 2021. https://doi.org/10.1016/j.anbehav.2021.03.006

Highlights

• Fighting and mating both involve the performance of repeated behaviours.

• Performance rate (vigour) and skill are of known importance for fighting success.

• Here, we discuss the possible role of skill in determining mating success.

• We highlight functional similarities between fighting and mating behaviours.

• We then identify mating behaviours for which a role for skill is strongly implied.

Whenever resources are limited and indivisible, fighting will evolve as a means to resolve ownership. Among such resources are mates, and individuals (usually males) of many species compete agonistically with rivals in order to gain access to potential mates. However, securing access is not necessarily enough to guarantee a mating or, if a mating is obtained, to guarantee that it is effective for securing reproductive success. Thus, in addition to fighting, individuals participate in a wealth of behaviours to maximize their reproductive success, from courtship to sperm competition to mate guarding. In recent years, the striking parallels between fighting and mating behaviour have become a subject of discussion. In particular, insights have been drawn from the predictions of contest theory to help us understand the use of repetitive signalling in courtship. Here, we take this discussion further, highlighting similarities between fighting and mating in the use of dynamic repeated behaviours, which function to (1) advertise quality and (2) convince or coerce an individual to relinquish the contested resource (gametes in terms of mating). We focus specifically on a performance trait of emerging interest in the field of animal contests, skill. We identify behaviours used throughout the mating process in which skill is likely to be of importance for securing success, and highlight key questions for future study.
