Fruit Fly Sexual Activity and Male Competition

Description

Results from an experiment on male fruit flies with different levels of sexual activity and competition from other males

Format

A data frame with 201 observations on the following 7 variables.

Mated

Was the fly allowed mating opportunities? (n or y)

Alone

Did the fly live alone? (y=yes or n= no, lived near another male)

Mating

How many mating opportunities was the fly given?

Total

Total duration of mating time over all opportunities (in seconds)

Size

Size of the thorax (in mm)

Lifespan

Lifespan (in hours, starting at the 12th day)

Activity

Number of times a movement detector was tripped starting in the 12th day

Details

Researchers randomly assigned virgin male fruit flies to one of two treatments: live alone or live in an environment where they can sense one other male fly. Flies were randomly allocated to either have mating opportunities with female flies or to not have such opportunities. Those flies that were given mating opportunities were given 3, 4, or 5 opportunities to mate (Mating measures this number). Researchers also measured size, lifespan and activity levels of the fruit flies.
