Data from: Is there a disease-free halo at species range limits? The co-distribution of anther-smut disease and its host species

Emily L. Bruns, Janis Antonovics & Michael Hood
1. While disease is widely recognized as affecting host population size, it has rarely been considered to play a role in determining host range limits. Many diseases may not be able to persist near the range limit if host population density falls below the critical threshold level for pathogen invasion. However, in vector- and sexually-transmitted diseases, pathogen transmission may be largely independent of host density and theory demonstrates that diseases with frequency-dependent transmission may persist...

Data from: Effect of the anther-smut fungus Microbotryum on the juvenile growth of its host Silene latifolia

Premise of the Study: Plant pathogens that form persistent systemic infections within plants have the potential to affect multiple plant life history traits, yet we tend to focus only on visible symptoms. Anther-smut disease of Silene latifolia caused by the fungus Microbotryum lychnidis-dioicae induces the anthers of its host to produce fungal spores in place of pollen, and the pathogen is primarily transmitted among flowering plants by pollinators. Nevertheless, most of its life cycle is...
