Data and code for: Disease outbreaks select for mate choice and coat color in wolves

We know much about pathogen evolution and the emergence of new disease strains but less about host resistance and how it is signaled to other individuals and subsequently maintained. The cline in frequency of black-coated wolves across North America is hypothesized to result from a relationship with canine distemper virus (CDV) outbreaks. We test this hypothesis using cross-sectional data from wolf populations across North America that vary in the prevalence of CDV and the allele that makes coats black, longitudinal data from Yellowstone National Park, and modeling. The frequency of CDV outbreaks generates fluctuating selection that results in heterozygote advantage that in turn impacts the frequency of the black allele, the optimal mating behavior, and the black wolf cline across the continent., Technical details about the analyses and the models are provided in the Material and Methods section of the article.

Data can be found in file 'dataYNPsurvivalanalysis340.RData', codes and step-by-step guidance are available to run the analysis and visualize results (file : SurvivalAnalysis_Cubaynesetalarticle.Rmd.
We used demographic data that included individual survival and immigration records, age, pack, and coat color phenotype and genotype for 340 wolves equipped with radio-collars in Yellowstone National Park, monitored between 1998 to 2020. Of these wolves, 181 were grey and 159 black (144 black heterozygotes, 10 black homozygotes, 5 of unknown genotype). We censored records at their last live sighting within the boundary of the park. 105 wolves were censored at the point they permanently dispersed outside of the National Park (n=101) or were killed by humans (n=4), deliberately or accidentally, within Yellowstone National Park.

## Description of the data and file structure

### 1 - Survival analysis

The file 'dataYNPsurvivalanalysis.RData' contains all data necessary to run the survival analysis described in Cubaynes et al.'s manuscript entitled 'Disease Outbreaks Select for Mate Choice and Coat Color in Wolves'.
It can be imported in software R using the load() function.
The list 'dataYNPsurvivalanalysis' contains the following components :

* $ID a vector of characters of length n=340 containing wolves identification number, other objects are in same order.
* $CR a matrix of 340 rows x 23 columns containing the capture history for each wolf (line), each year from 1998 to 2020 (column) with demographic and epidemiological status coded 1 : wolf alive inside YNP never exposed to CDV, 2: wolf alive inside YNP first exposure to CDV, 3 : wolf...
