Using a global survey of reef fish assemblages, we show that in contrast to previous theoretical and experimental studies, ecosystem functioning (as measured by standing biomass) scales in a non-saturating manner with biodiversity (as measured by species and functional richness) in this ecosystem. Our field study also shows a significant and negative interaction between human population density and biodiversity on ecosystem functioning (i.e., for the same human density there were larger reductions in standing biomass at more diverse reefs). Human effects were found to be related to fishing, coastal development, and land use stressors, and currently affect over 75% of the world's coral reefs. Our results indicate that the consequences of biodiversity loss in coral reefs have been considerably underestimated based on existing knowledge and that reef fish assemblages, particularly the most diverse, are greatly vulnerable to the expansion and intensity of anthropogenic stressors in coastal areas

Terrorism: Communication and Rhetorical Perspectives

Georgia Southern University faculty member Gerald R. Ledlow co-authored “The Communication and Rhetoric of Terrorism” in the publication Terrorism: Communication and Rhetorical Perspectives. Book Summary: This volume offers the best available thinking and analysis on the topic of the rhetoric and communication of terrorism. Each of the chapters isolates a particular issue or concern and exposes the difficult choices and subsequent processes facing participants in the management of terrorism. By wrapping the analysis in a web of communication and rhetorical processes and theories, the authors develop unique perspectives from which to characterize these contexts. This volume is intended for multiple audiences, including those interested not only in the specific topic but in risk communication, crisis management, policy management and political science.https://digitalcommons.georgiasouthern.edu/health-policy-facbookshelf/1012/thumbnail.jp
