This dataset contains data from the analyses presented in the 'SIText' of the following paper:

Delcourt, M., M.W. Blows, J.D. Aguirre and H.D. Rundle. 2012. Evolutionary optimum for male sexual traits characterized using the multivariate Robertson–Price Identity. Proc Natl Acad Sci USA: In press. 

A subset of these data (excluding rows with values of zero for column #10, representing genetic males that sired no offspring) were previously used in the following paper:

Delcourt M., M.W. Blows and H.D. Rundle. 2009. Sexually antagonistic genetic variance for fitness in an ancestral and a novel environment. Proceedings of the Royal Society of London Biological Sciences 276: 2009 - 2014.

and were deposited in Dryad (DOI number 10.5061/dryad.0pn48s2t).

The dataset is saved as CSV file (i.e. values separated by commas). Each row corresponds to the offspring produced by a single Drosophila serrata female (one replicate in the assay) within the context of a male or female fitness assay in which the target individual of interest was derived from a paternal half-sibling breeding design. Missing values are indicated by a "." (without the quotation marks).

Female fitness assays measured the number of adult offspring produced by a single female when mated to a random male from the stock population used in the breeding design. These data were not used in the analyses in the SIText of the PNAS paper.

Male fitness was measured in a competitive assay by placing together in a vial one virgin son from the breeding design along with two virgin competitor males of similar age randomly chosen from a stock population into which a recessive orange-eye mutation had been introgressed. These males competed to fertilize a randomly chosen virgin orange-eye female that was free to oviposit in the same vial. Data consist of the number of wild-type and orange-eye adult offspring produced by the female, corresponding to individuals sired by the genetic male vs. competitor males respectively.


The dataset has following columns:

1) sire
Sire of the genetic individual used in the fitness assay (range: 2106-4960). Numbers are arbitrary sire identifiers.

2) dam
Dam of the genetic individual used in the fitness assay (range: 1-6). Numbers are arbitrary dam identifiers (nested within sire).

3) rep
Identifier of the genetic individual (i.e. replicate) used in the fitness assay (range: 1-5). Numbers are arbitrary identifiers (nested with sire x dam combination).

4) ID
unique identity number of the genetic individual used in the fitness assay (1-4178). Numbers are arbitrary.

5) block
The breeding design and hence fitness assays were conducted in three blocks (values: 2,3,4); there are no data from block 1.

6) order
Dams oviposited in each of two food environments (yeast and corn). This is identity of the food environment in which the she oviposited first (Y1=yeast first, C1=corn first). 

7) env
Food environment in which the fitness assay was conducted (y=yeast, c=corn).

8) sex
Sex of the genetic individual for which fitness was being estimated: f=female (i.e. daughter from breeding design), m=male (i.e. son from breeding design)

9) femfit
Raw measure of female fitness: the number of adult offspring produced by a single daughter when mated to a random stock male (i.e. for sex=f replicates from column 8). Daughters that did not produce any offspring are not included in the dataset.

10) male_wild
Number of wild-type adult offspring emerging in male fitness assays (i.e. for sex=m replicates from column 8), indicating they were sired by the genetic male (i.e. the son from the breeding design). Replicates in which the female produced no wild-type offspring (i.e. the genetic male sired no offspring), but did produce some orange-eye offspring, are included.

11) male_mut
Number of orange-eye adult offspring emerging in male fitness assays (i.e. for sex=m replicates from column 8), indicating they were sired by the orange-eye competitor males.
