Evolutionary rescue occurs when genetic change allows a population to persist in response to an environmental change that would otherwise have led to extinction. Most studies of evolutionary rescue assume that species have either fully clonal or fully sexual reproduction; however, many species have partially clonal reproductive strategies in which they reproduce both clonally and sexually. Furthermore,...
Animals often use assessment signals to communicate information about their quality to a variety of receivers, including potential mates, competitors, and predators. But what maintains reliable signaling and prevents signalers from signaling a better quality than they actually have? Previous work has shown that reliable signaling can be maintained if signalers pay fitness costs for signaling at different...
Lavigne et al. developed models to investigate the adaptive colonization of sink environments by asexual organisms. Their results have clear relevance to the spread of infectious disease, but they may also provide insights into prokaryotic invasions into natural communities. Their results show that propagule pressure might not be a good predictor of invasion success in prokaryotes, suggesting that...
