Now, researchers at the University of Georgia have found that extreme low temperatures affect certain corals in much the same way that high temperatures do, with potentially catastrophic consequences for coral ecosystems.
A long-term study investigating how altering nutrient inputs to streams affected forest-dwelling organisms has yielded surprising results: In a paper published in the Online First edition of the journal Oecologia, researchers at the University of Georgia have shown that although nutrient enrichment led to increased production of aquatic insects, streamside predators that depend upon them as a food source did not benefit. In fact, they received significantly less nutrition from aquatic sources than did their counterparts at a similar untreated stream nearby.

Black-dotted brown moth can strip the leaves off oaks
Researchers at the University of Georgia are tracking an outbreak of caterpillars that can eat and strip the leaves off oak trees, potentially affecting the tree’s health for a year or more. The leaf-eating caterpillars have been confirmed in several counties surrounding Athens, including Clarke, Madison, Oglethorpe and Oconee. They are also possibly in both Barrow and Gwinnett counties, but UGA researchers fear they are also spreading throughout the state.

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. But in a paper just published in the journal Science, researchers in the UGA Odum School of Ecology report that in some cases, animal migrations could actually help reduce the spread and prevalence of disease and may even promote the evolution of less-virulent disease strains.

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.
Richard Hall, Assistant Research Scientist in the Odum School of Ecology, has received a 2010 Short Term Visiting Scholar Award from the National Institute for Mathematical and Biological Synthesis (NIMBioS).
Human activity is increasing the supply of nutrients, such as nitrogen and phosphorus, to stream systems all over the world. The conventional wisdom – bolstered by earlier research – has held that these additional nutrients cause an increase in production all along the food chain, from the tiniest organisms up to the largest predators. A long-term, ecosystem-scale study by a team of University of Georgia researchers, however, has thrown this assumption into question.

During a research trip to Puerto Rico, ecologist James Porter took samples from underwater nuclear bomb target USS Killen, expecting to find evidence of radioactive matter - instead he found a link to cancer. Data revealed that the closer corals and marine life were to unexploded bombs from the World War II vessel and the surrounding target range, the higher the rates of carcinogenic materials.
"When you remove the bomb, you remove the problem - but you've got to pick it up," said Porter.
While surveying fishes in Georgia’s Flint River, Byron and Mary Freeman noticed that a certain darter fish had a striking orange color in its fins—much different than the Blackbanded darter that is prominent in the southwest Georgia River. The University of Georgia researchers had indeed come across a new species: the Halloween darter or Percina crypta.
“The Halloween darter is a great example of ‘cryptic biodiversity’—species that have gone unrecognized because they look a lot like other species that are known,” explained Mary, an ecologist with the U.S. Geological Survey and the UGA Odum School of Ecology. “Ichthyologists have documented many new fish species in the southeastern U.S., showing that despite nearly 100 years of scientific study of fishes in this region, there are still surprises.”
Sonia Altizer, associate professor in the Odum School of Ecology, and Chad Fertig, assistant professor of physics in the Franklin College of Arts and Sciences, were among 68 researchers honored with the Presidential Early Career Award for Scientists and Engineers (PECASE) - the highest honor bestowed by the United States government on scientists and engineers beginning their careers.

Current models of global climate change predict warmer temperatures will increase the rate that bacteria and other microbes decompose soil organic matter, a scenario that pumps even more heat-trapping carbon into the atmosphere. But a new study led by a University of Georgia researcher shows that while the rate of decomposition increases for a brief period in response to warmer temperatures, elevated levels of decomposition don’t persist.
The University of Georgia Odum School of Ecology will host “Aquatic Conservation Science: Merging Theory and Application” on Oct. 3-4. The symposium is being held in honor of the careers of emeritus faculty members Judith L. Meyer and Gene Helfman.
A $190,000 grant from Southern Sustainable Agriculture, Research and Education will help the University of Georgia's Odum School of Ecology study the use of shrubby perennial legumes such as false indigo in making soil more suitable for organic farming.
Traditionally, the study of infectious diseases has taken two distinct routes, with epidemiologists focusing on quantifying disease outbreaks while researchers in fields such as microbiology and genetics have concentrated on the infectious agents themselves and the mutations they undergo.
UGA ecologist Pejman Rohani said understanding both aspects of infectious diseases is critical to revealing the complex dynamics that drive epidemics such as dengue fever and is working to combine the traditionally separate fields of study.
New research that crosses several species boundaries shows that when animals must choose less-than-preferred mates, females and males apparently have ways to compensate that increase the chance their offspring will survive. The study, recently published in the Proceedings of the National Academy of Sciences, adds weight to the Compensation Hypothesis, a proposal that has given insight into how individuals can pass on their genes even under less than ideal circumstances.
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.
It’s not just your imagination. Providing the first-ever definitive proof, a team of scientists has shown that emerging infectious diseases such as HIV, Severe Acute Respiratory Syndrome (SARS), West Nile virus and Ebola are indeed on the rise.
As Bud and Mary Freeman describe a recent trip to Ecuador to collect fish samples to help guide local conservation policy, their story is abundant with color—giant electric blue butterflies, orchids rampant in the lush landscape and tropical fish species with a variety of interesting patterns.
