Country Ibis, City Ibis 09/28/21 Angela Hsiung
The human population in Florida has boomed in the last few decades following migration of people from other states and countries, resulting in rapid urbanization.

UGA Radon Program 09/16/21 Maria M. Lameiras
University of Georgia Cooperative Extension’s radon testing program — a holistic program that combines radon education outreach with research, testing and mitigation — has helped optimize sampling and testing methodology for radon in water throughout the U.S. The program has influenced national standards in radon testing.
A new $1.5 million grant from the National Oceanic and Atmospheric Administration (NOAA) will help UGA scientists delve into the dynamics of coastal Georgia wetlands, researching how collapsing marshes can affect property values and storm resiliency in coastal communities. CAES News
Balancing Act 09/07/21 Kristen Morales
The forces at work in a marsh require a delicate balancing act. Rising and falling tidewaters keep clumps of Spartina grasses from growing too dense. But too much water makes it difficult for them to survive. Tip this balance too far in either direction and the marsh ecosystem collapses, resulting in a population of different plants — or no plants at all.
To support efforts to isolate genes responsible for water intake, Aggrey and Rekaya have been awarded a grant through the U.S.-Egypt Science and Technology Joint Fund to pursue a project titled “Improving the Efficiency of Water Intake Utilization in Poultry.” CAES News
Water Scarcity 08/25/21 Claire Sanders Kinnard
With nearly 2.5 million employed in an industry that produces 1.1 billion broilers per year, Egypt’s poultry industry is booming. Because of its dry climate, however, the country’s production levels are heavily reliant on producers’ ability to use resources efficiently without compromising output.
After molting into adults, periodical cicadas will move or fly to nearby vertical structures, especially shrubs and trees. The females will eventually lay their eggs on the ends of tree branches. CAES News
Tree Flagging 07/23/21 Ashley Hoppers
The emergence of Brood X exceeded expectations in north Georgia, as those of us who happen to reside in the “cicada zone” observed droves of periodical cicadas during the peak of the event. Over the past weeks, the song of the male periodical cicada has faded and fewer of these fascinating insects remain, but a sign of their passing is still evident.
