Host disease tolerance predicts transmission probability for a songbird pathogen

Disease tolerance reduces the per-pathogen fitness costs of infection for hosts and is an important component of host adaptation to pathogens. However, how disease tolerance affects host transmission potential is not well understood, especially because there are many potential mechanisms that facilitate host tolerance. For example, tissue-specific host tolerance leads to the reduction of host pathology, regardless of pathogen load. Hosts may also exhibit behavioral tolerance, where normal behaviors are maintained even while harboring high pathogen loads. Here, we examined the impacts that tissue-specific and behavioral tolerance have on transmission in house finches (Haemorhous mexicanus) infected with a common and highly virulent bacterial pathogen, Mycoplasma gallisepticum (MG). MG causes conjunctivitis in house finches and severely reduces population numbers after it arrives in a new area. Wild house finch populations differ in tissue-specific tolerance to MG and here we assessed how..., , , # Data from: Host disease tolerance predicts transmission probability for a songbird pathogen

This dataset includes both data and code used for all analyses in the manuscript \"Host disease tolerance predicts transmission probability for a songbird pathogen\". This paper explores the effects of host disease tolerance on the transmission of a pathogen.

## Description of the data and file structure

The Data Dictionary (Henschen et al data dictionary 20240314.csv) describes each variable (column) in the dataset (Henschen et al data 20240314) and is also reproduced below. The .R file (Henschen et al for submission 20240314.R) contains the annotated code used to analyze this dataset. The .Rproj file (Henschen et al Submission 20240314.Rproj) allows you to run all code directly if opened in R Studio.
