The flies used were an\N outbred stock. Sexual activity was manipulated by supplying individual\N males with one or eight receptive virgin females per day. The\N longevity of these males was compared with that of two control types.\N The first control consisted of two sets of individual males kept with\N one or eight newly inseminated females. Newly inseminated females will\N not usually remate for at least two days, and thus served as a control\N for any effect of competition with the male for food or space. The\N second control was a set of individual males kept with no females.\N There were 25 males in each of the five groups, which were treated\N identically in number of anaesthetizations (using CO2) and provision of\N fresh food medium.\N \N SOURCE:\N Figure 2 in the article "Sexual Activity and the Lifespan of Male\N Fruitflies" by Linda Partridge and Marion Farquhar. _Nature_, 294,\N 580-581, 1981.\N \N VARIABLE DESCRIPTIONS:\N Columns Variable Description\N ------- -------- -----------\N 1- 2 ID Serial No. (1-25) within each group of 25\N (the order in which data points were abstracted)\N \N 4 PARTNERS Number of companions (0, 1 or 8)\N \N 6 TYPE Type of companion\N 0: newly pregnant female\N 1: virgin female\N 9: not applicable (when PARTNERS=0)\N \N 8- 9 LONGEVITY Lifespan, in days\N \N 11-14 THORAX Length of thorax, in mm (x.xx)\N \N 16-17 SLEEP Percentage of each day spent sleeping\N \N \N SPECIAL NOTES:\N `Compliance' of the males in the two experimental groups was documented\N as follows: On two …
