Supplemental feeding of wildlife can increase the spread of some infectious diseases and decrease the spread of others. A new study by University of Georgia ecologists has found that the outcome depends on the type of pathogen and the source of food.
A new study by University of Georgia ecologists, just published in the journal Proceedings of the Royal Society B, has found that winter-breeding butterflies are at increased risk of disease, a finding that could apply to other migratory species as well. Planting tropical milkweed, available at many garden centers, makes the problem worse.

Streams that once sang with the croaks, chirps and ribbits of dozens of frog species have gone silent. They’re victims of a fungus that’s decimating amphibian populations worldwide.
Such catastrophic declines have been documented for more than a decade, but until recently scientists knew little about how the loss of frogs alters the larger ecosystem. A University of Georgia study that is the first to comprehensively examine an ecosystem before and after an amphibian population decline has found that tadpoles play a key role keeping the algae at the base of the food chain productive.
Research at the Agroecology Laboratory at the UGA Odum School of Ecology has led to the creation of organic farming enterprise budgets. Prior to this development, the economic decision-making tool used to estimate profitability was not widely available for organic production.
“Centuries of extensive tillage have caused much of our native topsoil to be washed into rivers,” said Krista Jacobsen, a recent Odum School Ph.D. graduate. “Many farmers in the Southeast inherit these degraded soils and it is important to develop and study farming practices that can restore soil and allow it to be farmed profitably at the same time. That’s where enterprise budgets come in.”
Stressed corals lose the symbiotic algae that help them survive in a process known as bleaching, but University of Georgia researchers have discovered that one subtype of the symbiotic algae that live mostly in shallow-water corals of the Caribbean provide resistance to environmental stress.
The researchers, who include plant biologists Gregory Schmidt and Brigitte Bruns and ecologists William Fitt and Jennifer McCabe Reynolds, showed for the first time that clade A Symbiodinium has complementary mechanisms for surviving in its coral hosts during periods of warmer-than-normal water temperatures and intense late-summer sun.
When seeing a need to provide recycling for UGA football games, the Odum School's Ecology Club quickly stepped up to the plate. Clearly, this group of undergraduates is passionate about recycling and respecting the UGA campus. Student volunteers pair up with the Athens-Clarke County Recycling Division, who provides supplies. Every game, the aluminum cans are separated and donated to Habitat for Humanity and the Ronald McDonald House Foundation. For more information on the Ecology Club's recycling efforts, please visit the official site of UGA Game Day Recycling.
Parasites can decimate amphibian populations, but one University of Georgia researcher believes they might also play a role in spurring the evolution of new and sometimes bizarre breeding strategies.
A pioneering study on the effects of nitrate, a form of nitrogen, in streams was recently published in Nature, with a team of 31 researchers including major contributions by Ashley M. Helton, a graduate student in the university's Odum School of Ecology.
The study demonstrated how varying amounts of nitrate are biologically processed in streams. And with the push for development of alternative fuels, it is important to note that excessive amounts of nitrogen may be created during the process of producing corn-based ethanol.
