[ Watch the Video ] Human activity, habitat disruption may affect migration patterns and spread of infectious diseases There's a most unusual gym in ecologist Sonia Altizer's lab at the University of Georgia in Athens. The athletes are monarch butterflies, and their workouts are carefully monitored to determine how parasites impact their flight performance. With support from the National Science Foundation (NSF), Altizer and her team study how animal behavior, including long distance...

It's a common assumption that animal migration, like human travel across the globe, can transport pathogens long distances, in some cases increasing disease risks to humans. West Nile Virus, for example, spread rapidly along the East coast of the U.S., most likely due to the movements of migratory birds. But in a paper just published in the journal Science, researchers in the University of Georgia Odum School of Ecology report that in some cases, animal migrations could actually help reduce...

Traveling long distances spurs the evolution of larger and pointier wings A University of Georgia study has found that monarch butterflies that migrate long distances have evolved significantly larger and more elongated wings than their stationary cousins, differences that are consistent with traits known to enhance flight ability in other migratory species. As part of a National Science Foundation and UGA-funded study, researchers in the Warnell School of Forestry and Natural Resources and...

It's a paradox that has confounded evolutionary biologists since Charles Darwin published On the Origin of Species in 1859: Since parasites depend on their hosts for survival, why do they harm them?A new University of Georgia and Emory University study of monarch butterflies and the microscopic parasites that hitch a ride on them finds that the parasites strike a middle ground between the benefits gained by reproducing rapidly and the costs to their hosts. The study, published in the early...
