Mating activity for water striders
A dataset with 10 observations on the following 3 variables.
|| Hyper-aggressice male in group?
||Proportion of time the female water striders were in hiding|
||Measure of mean mating activity (higher numbers meaning more mating)|
Water striders are common bugs that skate across the surface of water. Water striders have different personalities and some of the males are hyper-aggressive, meaning they jump on and wrestle with any other water strider near them. Individually, because hyper-aggressive males are much more active, they tend to have better mating success than more inactive striders. This study examined the effect they have on a group. Four males and three females were put in each of ten pools of water. Half of the groups had a hyper-aggressive male as one of the males and half did not. The proportion of time females are in hiding was measured for each of the 10 groups, and a measure of mean mating activity was also measured with higher numbers meaning more mating.
