Scientists studying how large-scale environmental disruptions affected ancient societies

John Day, Distinguished Professor Emeritus in LSU's College of the Coast & Environment, has collaborated on a new analysis of societal development with Joel Gunn of the University of North Carolina at Greensboro, William Folan of the Universidad Autonoma de Campeche in Mexico, and Matthew Moerschbaecher of the Louisiana Oil Spill Coordinators Office. Gunn and Folan are Mayan archaeologists and Moerschbaecher is a graduate of LSU's oceanography program. They report that over the past 10,000 years humanity has experienced a number of foundational transitions, or "bottlenecks." During these periods of transition, the advance or decline of societies was related to energy availability in the form of a benign climate and other factors.

Study reveals key locations for declining songbird

Many of North America's migratory songbirds, which undertake awe-inspiring journeys twice a year, are declining at alarming rates. For conservation efforts to succeed, wildlife managers need to know where they go and what challenges they face during their annual migration to Latin America and back. For a new study published by The Condor: Ornithological Applications, researchers in six states assembled an unprecedented effort to track where Prothonotary Warblers that breed across the eastern U.S. go in winter—their "migratory connectivity"—and found that nearly the entire species depends on a relatively small area in Colombia threatened by deforestation and sociopolitical changes.
