- Good guys do not always come last in goals. In this study we have shown that it is possible for non-aggressive males to have advantages, says John W.Pepper who is assistant professor in the Department of Ecology and Evolutionary Biology at the University of Arizona.
Along with evolutionary biologist Omar Tonsi Eldakar at Binghamton University, who led the study, he would find out why there are very few hyper aggressive males in water Skaters world.
They collected therefore water runners from nature, and to distinguish them from each other, the researchers used toothpicks with paint on to tingle them on their backs with unique color combinations.
When hyper aggressive males were placed along with less aggressive males and females, took the former over the party and the modest vannløperhannene was left entirely without lady company.
Females fled instead of to an area where it only last non-aggressive males. It turned out that the mood then immediately became much more romantic - and far more matings were successfully completed.
The common and more modest behavior of the rest of the males accounted collectively a more successful dusties buffet pairing project, simply because it created an environment that vannløperhunnene could live with.
- Individually, would the non-aggressive males get a smaller piece of the pie, but as a group these a bigger cake, because they do not chase away females, or assume ster them so powerful that they are unable to reproduce, says Pepper in a press.
