title: The Rachelbot: Investigation of Persona-Based Chatbots. In Data Science & Engineering Master of Advanced Study (DSE MAS) Capstone Projects

description: Creating agents that closely mimic human conversational patterns has been a major goal of research and industry for decades. Recent advances in recurrent and transformer deep learning architectures have made significant progress toward open domain chatbots that capture the highly contextual nature of conversations. In the last several years, researchers have turned to personas as one way of improving dialogue quality. In this project, current methods for building persona-based conversational agents are tested using a chatbot of a popular character (Rachel from the TV show Friends). Our aim is to: 1) deliver an engaging Friends experience to fans of the show, 2) assess chatbot deep learning architectures, and 3) establish the limits of contemporary approaches and potential areas for additional research.

title: UGA Variety Testing Soybean Evaluations 2016-2019: ARDN products

description: ARDN provides dataset annotations which facilitate interoperability. For information on how to use ARDN annotations and other data products, see https://agmip.github.io/ARDN/ARDN_how.html. This data was collected and published by University of Georgia's Statewide Variety Testing program from 2016-2019. It consists of experimental (non-regulated) and commercially-released soybean germplasm entered by seed companies and public institutions. Tests were conducted at 7 university-owned farms throughout Georgia, and include environments from the lower Coastal Plain to the southern Appalachians. Locations include Blairsville, Rome, Griffin, Athens (Watkinsville), Midville, Plains and Tifton. Four locations hosted dryland tests in addition to irrigated tests from 2016-2018. In 2019, dryland testing was discontinued in favor of another irrigated environment including all varieties. The number of years a variety was tested varies since their inclusion is determined by the respective test participant. Soil types differed between locations. Initial soil fertility for P and K is categorized, and actual rates of applied fertilizer are listed. Applied fertilizer rates were chosen to support a yield goal slightly above the maximum observed at the site in previous years. Ultra-late soybean plantings following corn harvest are part of this data set. Their economic viability is limited to the Coastal Plain region of Georgia, South Carolina, and perhaps Alabama. Varieties of maturity groups 5-8 all flower and mature similarly in that environment (planting window), and observed yields do not correlate to typical main-season plantings of those same varieties.

description: ARDN provides dataset annotations which facilitate interoperability. For information on how to use ARDN annotations and other data products, see https://agmip.github.io/ARDN/ARDN_how.html. This data was collected and published by University of Georgia's Statewide Variety Testing program from 2016-2019. It consists of experimental (non-regulated) and commercially-released corn hybrids entered by seed companies. Tests were conducted at 4 university-owned farms each year (5 total locations during period) throughout Georgia, and include environments from the lower Coastal Plain to the southern Appalachians. Locations include Blairsville, Rome, Griffin or Athens (Watkinsville) and Tifton. Not all hybrids appear in all environments in a given year. The number of years a hybrid was tested varies since their inclusion is determined by the respective seed company. Soil types differ between locations. Initial soil fertility for P and K is categorized, and actual rates of applied fertilizer are listed. Applied fertilizer rates were chosen to support a yield goal slightly above the maximum observed at the site in previous years. In most cases, the tests were harvested later than the optimum (30-35% dry matter) for silage production.

title: UGA Variety Testing Corn Grain Evaluations 2014-2019: ARDN products

description: ARDN provides dataset annotations which facilitate interoperability. For information on how to use ARDN annotations and other data products, see https://agmip.github.io/ARDN/ARDN_how.html. This data was collected and published by University of Georgia's Statewide Variety Testing program from 2014-2019. It consists of experimental (non-regulated) and commercially-released corn hybrids entered by seed companies. Tests were conducted at 6 university-owned farms each year throughout Georgia, and include environments from the lower Coastal Plain to the southern Appalachians. Locations include Blairsville, Rome, Griffin or Athens (Watkinsville), Midville, Plains and Tifton. At Rome and Tifton, both irrigated and dryland tests were performed. Not all hybrids appear in all environments in a given year. The number of years a hybrid was tested varies since their inclusion is determined by the respective seed company. Prior to 2019, separate randomizations were created at each location for short (RM 115 or less) vs mid (RM 116+) maturity hybrids. As a result, not all hybrids occurring in an environment can be directly compared. Soil types differed between locations. Initial soil fertility for P and K is categorized, and actual rates of applied fertilizer are listed. Applied fertilizer rates were chosen to support a yield goal slightly above the maximum observed at the site in previous years.

title: TERRA-REF Season 6 phenotypes and agronomic metadata in BrAPI format

description: This data represents a small subset of the TERRA-REF release available on Dryad (LeBauer et al 2020). In addition to harvested biomass for each cultivar, it includes plot location, planting date, harvest date, fertilizer application, genotype / accession names and metadata, and additional agronomic management metadata for a population of Sorghum bicolor evaluated over two growing seasons.
One way in which the data can be accessed is through a BrAPI-compliant endpoint at terraref.org/brapi. This dataset is a snapshot of the TERRA-REF BrAPI endpoint contents, representing the minimum data and metadata required to run a crop model. These BrAPI-compliant json files were downloaded from terraref.org/brapi. BrAPI is a data format widely used by plant breeders, and is described in Selby et al. 2019, https://doi.org/10.1093/bioinformatics/btz190

title: Data from: Carbon sequestration and biodiversity co‐benefits of preserving forests in the western United States

description: Forest carbon sequestration via forest preservation can be a viable climate change mitigation strategy. Here, we identify forests in the western conterminous United States with high potential carbon sequestration and low vulnerability to future drought and fire, as simulated using the Community Land Model and two high carbon emission scenario (RCP 8.5) climate models. High‐productivity, low‐vulnerability forests have the potential to sequester up to 5,450 Tg CO2 equivalent (1,485 Tg C) by 2099, which is up to 20% of the global mitigation potential previously identified for all temperate and boreal forests, or up to ~6 yr of current regional fossil fuel emissions. Additionally, these forests currently have high above‐ and below-ground carbon density, high tree species richness, and a high proportion of critical habitat for endangered vertebrate species, indicating a strong potential to support biodiversity into the future and promote ecosystem resilience to climate change. We stress that some forest lands have low carbon sequestration potential but high biodiversity, underscoring the need to consider multiple criteria when designing a land preservation portfolio. Our work demonstrates how process models and ecological criteria can be used to prioritize landscape preservation for mitigating greenhouse gas emissions and preserving biodiversity in a rapidly changing climate.

title: Reynolds Creek Experimental Watershed, Idaho (Sediment)

description: Automated Sigma pump samplers were used at all RCEW gauging stations to collect instantaneous point measures of suspended-sediment concentration. The US Department of Agriculture, Agricultural Research Service, Northwest Watershed Research Center initiated a stream discharge and suspended-sediment research program at Reynolds Creek Experimental Watershed in the early 1960s. Samples of suspended-sediment concentration were collected at Outlet, Tollgate, and Reynolds Mountain East gauging stations starting in the 1960s and continuing to the present. In early years, samples were collected manually during storm events using integrated samplers at the large weirs or simple grab samples at the smaller weirs. Later, a variety of early sediment samplers such as the U.S. PS-67 and U.S. PS-69 pumping samplers were tested and used in RCEW through cooperative efforts with other Agricultural Research Service locations, federal and state agencies, and universities. In recent years, automated Sigma pump samplers have been used at all gauging stations to collect a continuous record of instantaneous point measures of suspended-sediment concentration during high and low flows. Drop-box weirs have also performed well in RCEW over a wide range of discharges and sediment loads. Four additional types of stream-gauging devices are used in RCEW: (1) self-cleaning overflow V-notch (SCOV) weir, (2) 30 V-notch weir, (3) 90 V-notch weir, and (4) Parshall flume. All stations are equipped with stilling wells and floats for obtaining instantaneous measures of stage height. Instrument shelters are heated to permit collection of discharge and sediment data during cold winter periods. Gauging stations are visited on a weekly or biweekly basis to obtain independent stage height readings for error checking and to service all instrumentation. Stage height measurements were originally recorded using Leopold-Stevens A-35 and FW-1 strip chart recorders, later supplanted by electronic data loggers.

title: Reynolds Creek Experimental Watershed, Idaho (Snow)

description: Snow is the dominant form of precipitation in the Reynolds Creek Experimental Watershed (RCEW). Seven snow course sites were established in 1961, and one additional site was added in 1970. All sites are located in the high-elevation southern extent of the basin, where snow accumulation is greatest. Snow water equivalent (SWE) and depth have been sampled at multiple locations in RCEW since 1961. These data have been collected using snow tube methods that are generally considered the standard for manual measurement of SWE and snow depth. Snow water equivalent (SWE) has been measured at eight locations in RCEW every 2 weeks throughout the snow season (December 1 to June 1) for 35 water years (1962-1996). SWE was continuously monitored at site 176x07 using a snow pillow for 14 water years (1983-1996).

title: Reynolds Creek Experimental Watershed, Idaho (Soil Temperature)

description: Long-term soil temperature data were collected at the Reynolds Creek Experimental Watershed (RCEW) from 1981-1996 at five locations representing different climatic regimes and soils in the RCEW, ranging in elevation from 1190 to 2101 m. Each site is located in close proximity to a climate station on nearly level slopes. In most sites, there were six or seven measurement depths ranging from 2.5 to 240 cm; in 1990, new sensors were installed at all sites at depths of 5, 10, 20, 30, 40, 50, 60, 90, 120, and 180 cm. Each soil temperature depth profile is located near at least one neutron access tube and a precipitation gauge, and complete climate station information was collected either at the site or in reasonable proximity. Regular data collection started in 1981 or 1982, depending on the site. The temperature sensors used were YSI (Yellow Springs Instruments, Yellow Springs, Ohio) two-thermistor composite thermolinear components accurate to 0.15C. Data were originally collected in 1981 by connecting a hand-held voltmeter to the sensor leads, and individual sensors at different depths were read using a manual switch. These data were collected once each week, and the time was recorded. At some sites the switches were bypassed and hooked up to data loggers of various design resulting in more frequent (either 1 or 4 hour) recording intervals. Prior to 1990, soil temperature sensors were installed by attaching the sensors to a 0.05 m diameter wooden pole at the desired depth intervals, drilling a hole a with a drill rig (the soils in the RCEW are very rocky), inserting the pole in the drilled hole, and backfilling.

title: Reynolds Creek Experimental Watershed, Idaho (Climate)

description: An extensive, 33 year (1964-1996), climatic database has been developed for three climate stations on the Reynolds Creek Experimental Watershed (RCEW) located near the north end of the Owyhee Mountains in southwest Idaho.  The longest records (1964-1996) are for daily maximum and minimum temperature.  The length of record for other weather elements that include relative humidity, solar radiation,  wind speed and direction, daily Class A pan evaporation and barometric pressure varies, but in general is from 1974-1996.  Weather sensors have varied from hygrothermographs with spring-driven clocks and charts to electronic sensors with the data telemetered daily to the Northwest Watershed Research Center (NWRC) office in Boise, Idaho. Most of the data, since the early 1980's, were measured and stored electronically, therefore, hourly data are available for most climatic elements between the early 1980's and 1996.  These data can be accessed from the USDA-ARS Northwest Watershed Research Center database.

title: Reynolds Creek Experimental Watershed, Idaho (Precipitation)

description: An extensive precipitation database has been developed over the past 35 years with the first records starting in January 1962 and going through September 1996 from the Reynolds Creek Experimental Watershed located near the north end of the Owyhee Mountains in southwest Idaho.  Precipitation ranges from 236 mm on the lowest elevations at the north end of the watershed to 1123 mm at the southwest corner of the watershed.  The gauge network was changed in 1967-1968 from a single unshielded, universal-recording gauge at each location to the dual-gauge system that is presently used.  The dualgauge system consists of an unshielded and a shielded universal-recording gauge with orifices 3.05 m above the ground.  The number of dual-gauge sites was reduced from the original 46 in 1968 to 17 by 1996.  Also, several sites have been added and/or taken out of the network at various times for special studies.  There are continuous 35 year records available for 12 sites, 20-32 year records available for 8 sites, 10-19 year records available for 25 sites, and 4-9 year records for 8 sites for a total of 53 sites.  All of these data have been stored as breakpoint and hourly records in the USDA-ARS, Northwest Watershed Research Center database.  These breakpoint and hourly data are available.

title: Reynolds Creek Experimental Watershed, Idaho (Discharge)

description: Reynolds Creek Experimental Watershed discharge records are available for 13 stations with varying lengths of record ranging from 8 to 34 years. The U.S. Department of Agriculture, Agricultural Research Service, Northwest Watershed Research Center initiated a stream discharge and suspended-sediment research program at Reynolds Creek Experimental Watershed in the early 1960s. Continuous discharge measurements began at two sites in 1963, at three additional sites in 1964, and at eight additional sites in subsequent years. Contributing areas to these gauging stations range from 1.03 to 23,822 ha, selected to represent the broad range of environmental settings found across northwestern rangelands. Watershed drainage areas range from 1.03 to 23,822 ha with flow characteristics including ephemeral, intermittent, and perennial regimes. Discharge records are available for 13 stations with varying lengths of record ranging from 8 to 34 years. Drop-box weirs have performed well in RCEW over a wide range of discharges and sediment loads. Four additional types of stream-gauging devices are used in RCEW: (1) self-cleaning overflow V-notch (SCOV) weir, (2) 30 V-notch weir, (3) 90 V-notch weir, and (4) Parshall flume.

title: Reynolds Creek Experimental Watershed, Idaho (Lysimeter)

description: Lysimeters are instruments that measure water and/or solute movement in soils. The primary purpose for these lysimeters was to measure evapotranspiration (ET); these data describe changes in soil water during the snow-free season. In addition to measuring changes in total soil water, soil water content profiles and soil temperature profiles were measured within or adjacent to the lysimeters and are reported. Two pairs of soil lysimeters were installed in the RCEW in 1967, one pair at the Lower Sheep Creek climate station (designated the east and west lysimeters), separated, center to center, by 3.6 m, and the other pair at the Reynolds Mountain climate station (designated north and south), separated by 4.7 m. These lysimeters were hydraulic weighing lysimeters in which an inner cylindrical tank containing soil is set within a slightly larger outer cylinder. The inner cylinder rests on a coil of 0.05 m diameter butyl tubing filled with liquid (different low-freezing point liquids were used). The inner cylinder was 1.22 m deep and 1.47 m in diameter. The butyl tubing was hydraulically connected underground to a pressure transducer or manometer. The soil in each lysimeter was extracted from near the lysimeter sites. A soil core was taken by repeatedly excavating a soil cylinder of slightly larger diameter than the lysimeter and forcing the lysimeter sleeve over the soil to the depth of the sleeve (1.22 m). A metal plate was then forced across the cylinder bottom and welded to it in place. The inner cylinder, thus filled with soil, was then transported to the previously excavated outer cylinder via crane and set on the butyl tubing. A neutron probe access tube was installed in the center of each lysimeter to monitor soil water content changes with depth, and two 1.2 m ceramic suction "candles" were placed at the bottom of the lysimeters through a separate entrance. This operation resulted in an undisturbed soil monolith with extant vegetation in place. This is critical for two reasons: (1) Growing native vegetation under natural conditions is problematic in this environment, and plant development is slow. (2) The soil horizonation, particularly the argillic and calcic horizons which are both strongly embedded in coarse fragments, would be essentially impossible to reproduce artificially.

title: Data from: Data on foliar nutrient concentration of invasive plants in the recipient habitat and their native habitat

description: Higher foliar nitrogen concentration in plants is often attributed to higher biomass assimilation and subsequently higher plant growth rate. To understand the underlying mechanism of extensive growth rate of the highly invasive plant, Old World climbing fern (Lygodium microphyllum), in its native habitat in Queensland, Australia and recipient habitat in Florida, United States, the leaf tissue samples from the native and invaded habitats are analyzed. In each habitat we selected 3 different locations with varying habitat characteristics (soil type, land use history and coexisting vegetation). Plant aboveground tissue collected from each site were analyzed for macro- and micro-nutrients. Total C and N were measured with a Truspec CN Analyzer. Total Ca, Fe, Mg, K, Mn, and P in plant tissue samples were measured using inductively coupled plasma mass spectrometry (ICP –MS). Here we present the difference in foliar nutrient concentration of invasive plant species in their native habitats and invaded habitats.

title: Data from: Ploidy determination of buffel grass accessions in the USDA National Plant Germplasm System collection by flow cytometry

description: Buffel grass (Cenchrus ciliaris L. syn. Pennisetum ciliare (L.) Link) is an economically important warm-season perennial used primarily as a forage and range grass in many of the drier regions throughout the subtropics and tropics. Because buffel grass has excellent drought tolerance combined with desirable forage traits, it is an important forage and range grass in parts of Africa, including South Africa. It was introduced into many of the arid subtropical regions of the world, primarily Australia, North America, and South America, and today the species is grown on more than 50 million ha worldwide. Knowledge of the ploidy, meiotic behavior, and fertility of the plants used in hybridization programs became important because success depended upon using meiotically stable parental lines with compatible chromosome numbers. Little is known about the chromosome number of the buffel grass accessions in the USDA National Plant Germplasm System (NPGS) because the species has small chromosomes, that makes them difficult to count using traditional cytological methods. The DNA content of 568 accessions of buffel grass in the USDA National Plant Germplasm System was determined through flow cytometry to predict their ploidy levels. Based on DNA content, 308 accessions were determined as tetraploids with 36 chromosomes, 139 as pentaploids with 45 chromosomes, 20 as hexaploids with 54 chromosomes, two as septaploids with 63 chromosomes, and 99 as aneuploids. Chromosome counts of selected plants confirmed ploidy levels from DNA findings. Chromosome number of euploid plants could be predicted from the DNA data.
The findings from this investigation reveal that the accessions in the buffel grass collection consist of a wide range of cytotypes, including polyploids and aneuploids with varying chromosome numbers. This demonstrates the amount of chromosomal diversity that occurs within the species and this collection. Grass breeders who use the buffel grass germplasm in the NPGS in their breeding programs should ensure that they know the chromosome number of the material requested. The predicted ploidy levels in Supplementary Table 1 will provide that information to the breeders.
