Survival benefits of group living in a fluctuating environment

Sarah Guindre-Parker & Dustin Rubenstein
Group living is only predicted to arise when the fitness benefits outweigh the costs of sociality. Group-living species—including cooperatively breeding and family-living birds and mammals—occur most frequently in environments where climatic conditions fluctuate unpredictably from year-to-year. The fitness consequences of group living are thus expected to vary with changing environmental conditions, though few studies have examined this possibility. We examined whether living in large social groups improves adult survivorship in cooperatively breeding superb starlings (Lamprotornis...
