Careful Management

Even with careful management, within-field practices are often insufficient to prevent considerable nonpoint source pollution to adjacent streams. Water resources suffer from sediment, N, and P transported in surface runoff and N in subsurface movement when fields are cultivated up to stream banks. The maintainance of forested buffer systems between farmland and streams has been proposed as a remedy for mitigating pollution. Chemical movement through such a buffer system has been monitored for several years at the University of Georgia Coastal Plain Experiment Station. With the aid of that data, the Riparian Ecosystem Management Model is being developed to simulate biological, chemical, and hydrologic processes in order to evaluate the effectiveness of buffer system management for reducing the influx of pollutants to streams. The model allows an examination of the long-term potential of a buffer system under changing environmental conditions.

Bermudagrass (Cynodon spp.) is the foundation of the turfgrass industry in most tropical and warm-temperate regions. Development of bermudagrass as a turfgrass began in the early 1900s. Many of the cultivars commercially available today have been cooperatively released by the U.S. Department of Agriculture Agricultural Research Service (USDA-ARS) and the University of Georgia at the Coastal Plain Experiment Station in Tifton, GA.

The Long-Term Ecological Research (LTER) program has enabled me to conduct more broadly relevant science by addressing questions within an interdisciplinary framework and to unravel the causes for surprising ecological phenomena through persistent studies and collaborations. Educational opportunities within the LTER program have connected me to students from grades K–12 to graduate levels in new ways from the field to the classroom, across places from Florida to Alaska, and among disciplines in a collaborative setting. The audience for my research expanded as a consequence of my experiences in the LTER program, and I have learned how to more effectively communicate integrative research to large audiences of scientists, policy-makers, and the public, often through nontraditional media. The LTER program is foremost a network of people, and I have found that science evolves most successfully when ideas and information are shared voluntarily across backgrounds, disciplines, and cultures in a network of cultivated, trusting relationships. The Florida Coastal Everglades (FCE) is the LTER site where I am currently the principal investigator, but the LTER program has been a part of my life for most of my career. My experiences in the LTER program began in the early 1990s when I was a graduate student at the University of Georgia, where the Coweeta (CWT) LTER site is based. Although I was not formally a part of CWT, many of my friends and professors were, so the program influenced my development as a scientist. I remember my first field trip to CWT, led by Gene Helfman and Judy Meyer, and the fun of snorkeling in mountain streams where we camped and conducted a few experiments, including examining the effects of rapid consumption of s’mores and boiled peanuts on preschool children (Judy and Gene’s kids). LTER-related activities wove in and out of my graduate student experience, and the rewards of sharing of ideas, data, friendships, and boiled peanuts created in me a lifelong commitment to persistent, collaborative science. This sense of fulfillment, of being part of something larger, was reinforced at the Savannah River Ecology Laboratory (SREL), where I conducted my research.

Released in 2004 by the University of Georgia and U.S. Dept. of Agriculture, `Vernon' is an early season rabbiteye blueberry (Vaccinium ashei Reade), having large fruit size, good yields and excellent plant vigor. `Vernon', tested as T-584, was selected in 1990 at the Coastal Plain Experiment Station in Tifton, Ga. from a cross of T-23 × T-260. `Vernon' fruit ripens early with the cultivar Climax in south Georgia, and few days before `Premier'; however, `Vernon' flowers 5 to 10 days after the standard cultivars. On average over a 6 year period, `Vernon' yielded 5.8 kg/plant per season, compared to 3.1 and 4.5 kg/plant for `Climax' and `Premier', respectively. Berry stem scar, color, firmness, and flavor of the new cultivar are good to excellent. Berry size of `Vernon' is considerably large, averaging 2.05 g/berry over 4 locations in 2003, compared to only an average weight of 1.56 g/berry for `Climax'. `Vernon' berries are firmer than `Premier'. Propagation of the new cultivar is easily accomplished from softwood cuttings. Chill hour requirement is estimated to be in the range of 500 to 550 hours (<7 °C). `Vernon' should be planted with other rabbiteye blueberry cultivars with a similar time of bloom to provide optimum pollination. Propagation rights are controlled by Georgia Seed Development Commission, 2420 S. Milledge Avenue, Athens, GA 30606 (for more information go to www.gsdc.com).

Environmental science has no room for theoretical or methodological hegemony, and questions cannot be asked in the absence of purposeful design. Education must simultaneously engage students in thinking and doing, ideally in collaboration. Communication is a two-way process in which scientists are challenged to be credible and legitimate in conveying salient results to diverse audiences. Collaboration is about leveraging individual skills toward a common purpose, which can only succeed when trust exists between investigators. I was trained as an ecological anthropologist with an emphasis on behavioral and ecosystem ecology at the University of Montana and the Pennsylvania State University. I have conducted archaeological, behavioral, cultural, and historical research throughout the western and the southeastern United States, as well as in several countries in lowland South America, the Dominican Republic, and southern France. Currently, I am professor and head of the Department of Anthropology at the University of Georgia. In 1997, I was invited to join the Long-Term Ecological Research (LTER) program at the Coweeta site (CWT). CWT is based in the eastern deciduous forest of the southern Appalachian Mountains, and I was brought in to collaborate on regionalization of what had been exclusively a site-based project. Just prior to joining CWT, I had been involved for several years in regional conservation activities in Paraguay and Bolivia. Since 2002, I have served as principal investigator of CWT, leading the successful grant renewal efforts in 2002 and 2008. I recently completed the 2014 renewal effort, which was successful. There has been a dramatic shift over the period of my involvement in the LTER program in attitudes within the network to regionalization and participation by scientists from disciplines other than ecology (Gragson and Grove 2006; Robertson et al. 2012). Several colleagues and I have helped to foster this shift through our involvement on the LTER Social Science Standing Committee (1998–present), leadership in the LTER planning activities (2004–2007), and service on the LTER Executive Board (2008–2011). My experiences in the LTER program have influenced my ideas about the nature and conduct of environmental research.

ABSTRACTFormally established in the fall of 1947, the Laboratory of Archaeology at the University of Georgia is an archaeological research and collection repository. It is considered one of the premier institutions for curation of archaeological collections from the American Southeast. For over 70 years, the Laboratory has served as a repository for objects and associated records generated from archaeological projects and research undertaken by faculty, students, CRM professionals, and state and federal agencies. The Laboratory curates over 20,000 cubic feet of artifacts as well as paper and digital archives. In addition, the Laboratory houses the Georgia Archaeological Site File and manages data from more than 59,000 archaeological sites, including over 11,500 archaeological reports. In this paper, we explore implementation procedures for bringing legacy collections up to modern curation standards. We also outline how we migrate the data on paper records into the digital realm, articulating them within a comprehensive framework.

Abstract The efficacy of 14 insecticides for control of velvetbean caterpillars and stink bugs was evaluated at the University of Georgia Coastal Plain Experiment Station, Tifton, GA. The insecticides were foliar-applied on 31 Aug on ‘Cook’ soybeans planted on 17 May. Individual plots were 4 rows wide × 50 ft long with alleys 6 ft wide on each end and 2 border rows on each side, arranged in a RCBD with 4 replications. Each spray concentrate was applied with a CO2-powered backpack sprayer with 4, TX-12 nozzles on a 6 ft boom (2 nozzles per row) at 40 psi that delivered 17.6 gal/acre. Each plot was sampled prior to treatment and on 2, 7, 14 and 21 DAT, by taking a 20-sweep sample (15-inch diam net) from a single row. Soybeans were in the R5 growth stage (pods rilling with seeds) during the testing period. At 28 DAT, the percent defoliation was visually estimated for all plots. The data were subjected to ANOVA and Duncan’s multiple range test.

Surgical correction of an ingrown tail is indicated to relieve clinical signs of intertriginous dermatitis. The objective of this retrospective study was to identify the type and frequency of complications following caudectomy in dogs with ingrown tails. Medical records of dogs with ingrown tails treated with caudectomy from 2000 to 2010 at the University of Georgia Veterinary Teaching Hospital were reviewed. Data collected included signalment, preoperative infection status, surgical procedures performed, prophylactic antibiotic use, complications noted both during hospitalization and at suture removal, treatments instituted, and owner satisfaction. Seventeen dogs were identified for inclusion. At presentation, 4 of the 17 dogs (23.5%) were receiving antibiotics. Infection was present in 7 of the 17 dogs (41%), and 6 of the 7 cases resolved immediately postoperatively. All dogs received perioperative antimicrobial therapy, and 13 of the 17 dogs (76%) received antibiotics after surgery for an average of 13.5 days ± 5.2 days. Complications occurred in 2 of the 17 cases (12%) immediately after surgery, including decreased rectal sensation with adequate anal tone, failure to posture to defecate, and postoperative draining tracts. Complications were reported in 2 of 15 dogs (13%) at suture removal, including delayed wound healing and wound inflammation, persistent tail chasing behavior, and temporary changes in defecation habits. Caudectomy provided resolution of clinical signs with no long-term complications.

AJIL Unbound is pleased to announce three commentators who will discuss the article by Pierre-Hugues Verdier and Erik Voeten entitled “Precedent, Compliance, and Change in Customary International Law: An Explanatory Theory.” The article argues that rational choice scholars have overlooked key characteristics of customary international law and that those characteristics undermine the enforcement of customary norms through decentralized punishment. Instead, Verdier and Voeten contend, states may comply with customary international law even if their short-term interests are to defect, because states know that their decision to defect generates precedent that undermines the norm as a whole. Our commentators on this article are, first, Professor Tim Meyer, from the University of Georgia, who maintains that Verdier and Voeten overstate the distinction between custom and treaties. Second, Professor Jens David Ohlin, from Cornell, asks what happens to custom when states cannot appeal to long-term interests. He argues that compliance in these “one-shot” scenarios can be understood partly by considering the formation of plans by states which may act rationally in carrying through on their obligations without re-evaluating their plans. Finally, Professor Alejandro Lorite Escorihuela, from the University of Quebec at Montreal, argues that the role of precedent is clear from both the doctrine and practice of customary international law, so that it is unclear what rational choice methodology is adding to our understanding of custom, a critique he buttresses in part through an examination of some of the examples discussed in the article.

Field screening for potato leafhopper, Empoasca fabae Harris, resistance among peanut, Arachis hypogaea L., genotypes were conducted for three consecutive years (2001, 2002, and 2003) at the University of Georgia, Coastal Plain Experiment Station in Tifton, GA. Irrigated field trials were used for evaluations, and plants were grown without any pesticides other than preplant and occasional postemergence herbicides. Results from these replicated tests showed a wide-range of leafhopper damage. During each of the 3 yrs, ‘Georgia-01R’ consistently had the lowest leafhopper damage rating of all genotypes tested. Likewise, each year ‘Georgia Hi-O/L’ had the highest leafhopper damage rating. ‘Georgia Green’ and other cultivars and breeding lines were intermediate between Georgia-01R and Georgia Hi-O/L for leafhopper ratings. These field trials confirmed the multiple-pest resistant runner-type cultivar Georgia-01R as a new source of leafhopper resistance in peanut.

A new southern highbush blueberry cultivar named `Camellia' was released in 2005 by The University of Georgia and the USDA–ARS. `Camellia' is a hybrid containing mostly Vaccinium corymbosum and a small amount of V. darrowi. The new cultivar was selected in 1996 at the Coastal Plain Experiment Station in Tifton, Ga. from a cross of MS-122 × MS-6, and was tested as TH-621 in plantings at Alapaha, Ga. beginning in 1998. `Camellia' has an estimated chill requirement of 450 to 500 hours (<7 °C). It is an early- to mid-season cultivar, having berries that are large, with a very light blue color, and a small, dry picking scar. Berry firmness is good and flavor is very good. `Camellia' flowers 5 to 8 days after `Star' and `O'Neal' in south Georgia, and ripens 4 to 9 days after `Star', and with `O'Neal'. Plants are highly vigorous, with strong cane growth and an open, upright bush habit and a narrow crown. Yields have been similar to `Star' and greater than `O'Neal'. `Camellia' should be planted with other southern highbush blueberry cultivars with a similar time of bloom for cross-pollination (`Star' and `O'Neal' suggested). It is recommended on a trial basis at this time. `Camellia' requires a license to propagate. For licensing information and/or a list of licensed propagators, contact the Georgia Seed Development Commission, 2420 S. Milledge Avenue, Athens, GA 30606; or visit their website at www.gsdc.com.
