Broiler chicken (Gallus gallus domesticus) production is one of the largest agricultural sectors in the state of Georgia. Broiler litter produced by broiler facilities is rich in organic nitrogen (N), specifically urea, which can be mineralized by poultry litter urease-producing bacteria (PLUP) forming ammoniacal-N (NH3/NH4+). A large portion of NH3/NH4+ can be lost as ammonia (NH3) gas, which negatively impacts bird health and profitability. The release of NH3 from litter is strongly influenced by the pH of the litter. Flue-gas desulfurization gypsum (FGDG) has been suggested …

Abstract: Wildfires are of increasing concern in light of climate change, more frequent late summer droughts, and increasing incidence of human ignitions. There have been few studies examining the effects of wildland fires on soil macroinvertebrates in the Blue Ridge Mountains, in spite of the importance of these animals to soil processes, and their contributions to the …

As the result of anthropogenic disturbance, freshwater ecosystems are rapidly being destroyed worldwide. Accordingly, such impacts are also resulting in the loss of aquatic biodiversity. Specifically, the introduction of non-native aquatic species is becoming an increasing concern. Historically, many non-native freshwater fish introductions have been the result of commercial baitfish aquaculture and private aquarium release. Cyprinella lutrensis (the red shiner) is endemic to much of the central U.S., and its natural range does not extent east of the Mississippi River. Since the 1950’s, red shiner have been cultivated and transported across the globe as both bait and aquarium fish. During …

Algae, a polyphyletic group of aquatic primary producers, play a great part in earth’s biosphere. They produce half of the world’s oxygen and are major contributors to aquatic biodiversity. When conditions are favorable to a species, algae will bloom. Some algal species will produce algal toxins during a bloom as a potential mechanism to concentrate carbon. Due to the integral part they play in aquatic food webs, nutrient cycling and the potential for harmful algal blooms, algal communities are monitored to determine the health and safety of aquatic environments. Lake Sinclair in middle Georgia is a good model where in …

Roadways are among the most widespread and disruptive anthropogenic land use features that influence the behavior and movement of wildlife. Negative impacts include vehicle-induced mortality, habitat destruction and fragmentation, and creating barriers to movement which can have far-reaching sub-lethal effects. In an effort to improve upon historical methods of evaluating the influence of prominent landscape features, such as roads, on the movement of small and secretive wildlife, we are using a novel integration of emerging spatial analyses and tri-axial accelerometry in Timber Rattlesnakes (Crotalus horridus) from central Georgia. We used dynamic Brownian Bridge Movement Models to estimate motion …

Adenovirus has made major contributions in medicine by serving as a model DNA virus to study other viruses, such as human papillomavirus (HPV). Adenoviruses are a diverse family of nonenveloped, double-stranded DNA viruses that are ubiquitous to animals and humans. There are over 67 serotypes of human adenoviruses that can cause a variety of illnesses including, gastroenteritis, conjunctivitis and respiratory infections. Adenovirus can cause these infections by invading host cells and producing an environment that is favorable for viral replication. During the early phases of infection, adenovirus expresses various viral proteins such as E4 11k, which has multiple functions. One …

Late-Pleistocene fossil sites are uncommon in Georgia. However, Clark Quarry, a locality near Brunswick, Georgia, has yielded a large and diverse collection of vertebrate skeletal material dominated by cranial and post-cranial fossils of Columbian mammoths (Mammathus columbi) and giant bison (Bison latifrons). Screen washing of the fossiliferous sediment associated with the bones of the megafauna has produced a large number of microfossils. Here I describe fossil rodents from Clark Quarry. Cranial and post-cranial material of eight rodent taxa have been identified to date. Of these, five are found in the area today: Sigmodon hispidus, Peromyscus sp., …
