Co2 Flux And C Balance Due To The Replacement Of Bare Soil With Agro-Ecological Service Crops In Mediterranean Environment, Emanuele Radicetti, O. Adewale Osipitan, Ali Reza Safahani Langeroodi, Sara Marinari, Roberto Mancinelli
Haskell Agricultural Laboratory (Northeast Research and Extension Center)
Intensive agriculture practices often results in decomposition of organic matter, thus causing soil CO2 emissions. Agro-ecological service crop could be profitably cultivated to improve soil characteristics and reduce CO2 emissions under Mediterranean environment. Two-year field trials were conducted in central Italy. The treatments were three agro-ecological service crops (hairy vetch, oat, and oilseed rape) and a no-service cover. Plant development, soil characteristics, and CO2 emissions were measured. Oat and oilseed rape showed a rapid growth, while hairy vetch started to grow rapidly only after the cold period. Soil CO2 emissions trend was similar among the agro-ecological …
Effects Of Increased Precipitation On The Life History Of Spring- And Autumn-Germinated Plants Of The Cold Desert Annual Erodium Oxyrhynchum (Geraniaceae), 2019 Chinese Academy of Sciences, China

Biology Faculty Publications
Future increased precipitation in cold desert ecosystems may impact annual/ephemeral plant species that germinate in both spring and autumn. Our primary aim was to compare the life history characteristics of plants from spring-germinating (SG) and autumn-germinating (AG) seeds of Erodium oxyrhynchum. Plants in field plots with simulated increases in precipitation of 0, 30 and 50 % in spring and summer were monitored to determine seedling survival, phenology, plant size, seed production and biomass accumulation and allocation. Germination characteristics were determined in the laboratory for seeds produced by plants in all increased precipitation treatments. Increased precipitation in spring significantly improved survival …
Leveraging Image Analysis For High-Throughput Plant Phenotyping, 2019 University of Nebraska - Lincoln
Leveraging Image Analysis For High-Throughput Plant Phenotyping, Sruti Das Choudhury, Ashok Samal, Tala Awada
School of Natural Resources: Faculty Publications
The complex interaction between a genotype and its environment controls the biophysical properties of a plant, manifested in observable traits, i.e., plant’s phenome, which influences resources acquisition, performance, and yield. High-throughput automated image-based plant phenotyping refers to the sensing and quantifying plant traits non-destructively by analyzing images captured at regular intervals and with precision. While phenomic research has drawn significant attention in the last decade, extracting meaningful and reliable numerical phenotypes from plant images especially by considering its individual components, e.g., leaves, stem, fruit, and flower, remains a critical bottleneck to the translation of advances of phenotyping technology into genetic …
Hemipteran Pests Of Sugarcane In North America, 2019 Louisiana State Univ, Agr Ctr, Sugarcane Res Stn
Hemipteran Pests Of Sugarcane In North America, Blake E. Wilson
Faculty Publications
ing-sucking herbivores (Insecta: Hemiptera) represent one of the greatest threats to agricultural production worldwide. Hemipteran pests directly injure plants as well as vector disease-causing plant pathogens. Production of sugarcane (Saccharum spp.) in North America is impacted by a complex of Hemiptera including the sugarcane aphid, Melanaphis sacchari Zehntner (Aphididae); yellow sugarcane aphid, Sipha flava (Forbes) (Aphididae); West Indian canefly, Saccharosydne saccharivora (Westwood) (Delphacidae); sugarcane delphacid, Perkinsiella saccharicida Kirkaldy (Delphacidae); and sugarcane lace bug, Leptodictya tabida (Herric-Schaeffer) (Tingidae). None of these pests is consistently damaging to large amounts of sugarcane acreage, but regional outbreaks are common. The biology, ecology, and pest …
Influence Of Sorghum Cultivar, Phenological Stage, And Fertilization On Development And Reproduction Of Melanaphis Sacchari (Hemiptera: Aphididae), 2019 Louisiana State Univ, Ctr Agr, Sugarcane Res Stn
Influence Of Sorghum Cultivar, Phenological Stage, And Fertilization On Development And Reproduction Of Melanaphis Sacchari (Hemiptera: Aphididae), Blake E. Wilson, Jeffrey Davis, Thomas Reagan, Luna Lama
Faculty Publications
The sugarcane aphid, Melanaphis sacchari (Zehntner) (Hemiptera: Aphididae), is an invasive pest of grain sorghum, Sorghum bicolor (L) Moench (Poaceae). Since its first outbreak in sorghum in 2013, severe infestations have spread throughout the southern USA, causing major economic losses. Whereas insecticide applications can mitigate some of the pest's impacts, a sustainable ecology-based management program is needed to reduce reliance on chemical control. Two greenhouse assays examined the influence of selected host plant characteristics on M. sacchari life table parameters. We studied the effects of silicon (rates equivalent to 0 and 3,360 kg silicon per ha) and nitrogen (rates equivalent …

Research in Biology
Herbal medicines are a melee of complex organic chemicals, making it difficult to ascertain their direct mechanism of action. In contrast to mainstream pharmaceuticals, it is argued that herbal medicines are effective because of multiple constituents working synergistically. The complexity of herbal medicines may give them advantages over simpler pharmaceuticals in combating antibiotic resistant microbes, but these advantages can be difficult to quantitate. Popular literature frequently espouses the healing properties of herbal medicines, but many of these claims are not scientifically supported. Many gains could be realized in public health and medicine if more research was aimed at validating / …
Diversity Of Nitrogen Fixing Bacteria In A Sample Aquaponics Ecosystem, 2019 University of Southern Maine
Diversity Of Nitrogen Fixing Bacteria In A Sample Aquaponics Ecosystem, Joshua Trombley, Haley Depner
Thinking Matters Symposium Archive
In natural ecosystems, nitrogen-fixing bacteria act as the primary source of useable nitrogen for many plants by converting atmospheric N2 into ammonia. In an aquaponics system, however, the primary source of ammonia is provided by fish waste. We are investigating the effect of this ammonia saturation on the diversity of nitrogen-fixing bacteria in a sample aquaponics system. We seek to answer two fundamental questions: First, what nitrogen fixing microbes are present in these systems? Second, does the character of these microbial communities have any effect on plant growth? In order to answer these questions, we first determine whether nitrogen-fixing bacteria …
Comparing Methods And Technologies For Assessing Vertical Size Distribution Of American Beech Leaves (Fagus Grandifolia Ehrh), 2019 University of Southern Maine
Comparing Methods And Technologies For Assessing Vertical Size Distribution Of American Beech Leaves (Fagus Grandifolia Ehrh), Adeline Casali
Thinking Matters Symposium Archive
The American beech (Fagus grandifolia Ehrh) is a deciduous species that occurs throughout the eastern United States and Southeast Canada. This species grows 20–35 meters in height and is tolerant of a range of environmental conditions. Because beech occurs over a wide geographical and ecological range, it is ideal for comparative studies between sites or environmental conditions. Here we report on the relative size of beech leaves collected from different heights above the forest floor. We then determine if morphological trends between upper and lower canopy were consistent between live fall leaves and senesced mid-winter leaves that remain attached to …
Influence Of Indirect Cues And Vegetation Density On Foraging Behavior In Snowshoe Hares (Lepus Americanus), 2019 University of Southern Maine
Influence Of Indirect Cues And Vegetation Density On Foraging Behavior In Snowshoe Hares (Lepus Americanus), Zachary Lankist
Thinking Matters Symposium Archive
Prey avoid chemical cues from predators at feeding sites because the risk of death outweighs the benefit of food. However, we lack information regarding avoidance of chemical cues from competitors as well as how foraging behavior changes alongside vegetative cover. To test if chemical cues and vegetative cover alter prey vigilance, number of visits, and time spent at feeding sites, I observed snowshoe hares (Lepus americanus) in plots containing coyote (Canis latrans; predator) and moose (Alces alces; competitor) urine across a spectrum of vegetation densities. Snowshoe hares significantly reduced the number of visits to feeding plots when coyote or moose …

Teaching And Learning Software In Landscape Architecture: A Survey Of Software Use Amongst Faculty And Students, Benjamin H. George, Peter Summerlin, Taz Fulford
Landscape Architecture and Environmental Planning Faculty Publications
Competency in computer software is integral to the profession of landscape architecture, replacing many of the traditional drawing and drafting tools used. This article seeks to capture the current state of software in academia from the perspective of both faculty and students, and to determine if students are achieving the learning levels that faculty are targeting in their courses. Results show that students are attaining faculty’s learning targets, yet students report discontent with the learning process, suggesting that more emphasis is needed to help students understand the role of software in the design process.
