Despite the clear fitness consequences of animal decisions, the science of animal decision making in evolutionary biology is underdeveloped compared with decision science in human psychology. Specifically, the field lacks a conceptual framework that defines and describes the relevant components of a decision, leading to imprecise language and concepts. The ‘judgment and decision-making’ (JDM) framework in human psychology is a powerful tool for framing and understanding human decisions, and we apply it here to components of animal decisions, which we refer to as ‘cognitive phenotypes’. We distinguish multiple cognitive phenotypes in the context of a JDM framework and highlight empirical …
Influence Of Fertilizer Source And Irrigation Regimen On Containerized Production Of Coleus (Plectranthus Scutellarioides (L.) Codd) 'Solar Sunrise' And Management Of Bermudagrass (Cynodon Dactylon (L.) Pers. X C. Transvaalensis Burtt-Davy) 'Tifway', Kayla Renee Sanders
LSU Master's Theses
Fertilizer nutrient losses through leachate and runoff from excessive irrigation in nursery container production and turfgrass management can be high and have negative environmental impacts. The objective of this research was to examine the influence of fertilizer source and irrigation regimen on nutrient losses during nursery container production and turfgrass management. During the container production of coleus (Plectranthus scutellarioides (L.) Codd) 'Solar Sunrise', four fertilizer treatments: an unfertilized control; a controlled-release (CRF); a water-soluble (WSF); and a combination of 10% WSF and 90% CRF, were incorporated into a pine bark substrate at 0.30 kg N and P·m-3 in 3.7-L containers …

Testing Fitness-Related Phone Application Technology In Physical Activity Classes, Angela Nicole Simonton
Testing Fitness-Related Phone Application Technology In Physical Activity Classes, Angela Nicole Simonton
LSU Master's Theses
Many young adults are inactive (Centers for Disease Control and Prevention, 2010) and time spent on smartphones and applications (“apps”) is high (Pew Research Center, 2014; The Nielsen Company, 2014). Technology is often viewed as a barrier to health behavior, so seeking ways of using technology to facilitate physical activity (PA) and other health-related behaviors could be beneficial. The Social Cognitive Theory (SCT) framework was used to determine if the NexTrack smartphone app could increase PA behaviors and SCT-related constructs among university students in PA courses. Participants in the NexTrack app intervention group were hypothesized to report increased psychosocial and …
Effects Of Glyphosate On Soybean Nutrition, Endophytic Colonization By Cercospora Cf. Flagellaris And Development Of Cercospora Leaf Blight, Teddy Garcia Aroca
Effects Of Glyphosate On Soybean Nutrition, Endophytic Colonization By Cercospora Cf. Flagellaris And Development Of Cercospora Leaf Blight, Teddy Garcia Aroca
LSU Master's Theses
Glyphosate (Roundup®, Monsanto, Inc., St. Louis, MO) is the most widely used herbicide in the world because of its broad spectrum and its efficacy in controlling annual broadleaf weeds and undesired grasses. The effect of glyphosate on mineral nutrition and plant diseases has been an important topic during the past decade, because of its controversial effects on plant mineral nutrition. In order to test the hypothesis that glyphosate affects soybean mineral nutrition, and therefore predisposes soybean to Cercospora leaf blight, six glyphosate-resistant (GR) soybean varieties were either not treated or treated with glyphosate in field experiments. Plants were then evaluated …

Effects Of Truck Based Ultra-Low Volume Mosquito Adulticides On Honey Bees (Apis Mellifera) In A Real World Scenario, Vivek Pokhrel
LSU Master's Theses
Honey bees are crucial pollinators for many economically important fruit crops. The recent honey bee colony decline in the United States and other regions of the world has caused concern among commercial beekeepers, research groups, the government, and the general public. The role of pesticides in recent honey bee declines has not been fully determined. In Louisiana, it is a common practice to spray truck based ultra-low volume mosquito adulticides in Integrated Mosquito Management Programs to control mosquitoes and minimize the risk of vector borne viruses such as West Nile, chikungunya, and Zika. This study measured the effects of truck …

To analyze the insect pest reports, complaints from students on ants, bed bugs and cockroaches were selected from the database. From the 16-year data set, the growth trend of reports of ants, bed bugs and cockroaches was found to be increasing. The highest reported month and year for ants was September 2004. In August 2008, cockroaches were most reported on. Bed bug reports peaked in October 2009. Based on the reports, the …
Geographic Distribution And Severity Of Strobilurin Fungicide Resistance Among Rhizoctonia Solani On Rice In Southwestern Louisiana, Allysson Gayle Lunos
Geographic Distribution And Severity Of Strobilurin Fungicide Resistance Among Rhizoctonia Solani On Rice In Southwestern Louisiana, Allysson Gayle Lunos
LSU Master's Theses
Strobilurin fungicide resistance threatens rice production in southwestern Louisiana. Strobilurins are the often relied upon method of managing sheath blight development due to the lack of strong genetic resistance to this disease in the currently available rice germplasm. However, isolates of Rhizoctonia solani AG 1-IA causing sheath blight were reported resistant to azoxystrobin near Mowata, LA in 2011. To determine the geographic distribution and severity of azoxystrobin resistance, 40 commercial rice fields in southwestern Louisiana were sampled for isolates of R. solani. Sensitivity to pyraclostrobin and trifloxystrobin was also assessed to investigate cross-resistance. A genetic test was used to …
Development Of Functional Markers For Resistance To Leaf Scald In Sugarcane, Andres Felipe Gutierrez Viveros
Development Of Functional Markers For Resistance To Leaf Scald In Sugarcane, Andres Felipe Gutierrez Viveros
LSU Doctoral Dissertations
Leaf scald, caused by Xanthomonas albilineans, is a major sugarcane disease worldwide. The disease is managed primarily with resistant cultivars obtained through classical breeding; however, the erratic symptom expression hinders the reliability and reproducibility of the selection process. The development of molecular markers associated with incompatible/compatible reaction can overcome this limitation. Suppression subtractive hybridization (SSH) and quantitative trait locus (QTL) mapping were the strategies used to find leaf scald resistance-associated genes and molecular markers in sugarcane. SSH results showed that genes involved in signal perception and transduction, and DNA binding, were highly expressed in the resistant clone LCP 85-384 compared …

Integrated Methods For Controlling Gastrointestinal Nematode Infections In Ewes And Lambs, Sarah Tammy Nicole Keeton
LSU Doctoral Dissertations
Gastrointestinal nematode (GIN) parasites cause extensive damage to small ruminants, and Haemonchus contortus is a major concern to production worldwide. With the development of GIN resistance to anthelmintics, alternative strategies for control are needed. The major component of this study compared two strategies for effect on animal health and changes in GIN population. One flock of ewes and lambs (Strategy 1, S1) employed targeted selective treatment (TST) with an anthelmintic based on FAMACHA score, and one flock (Strategy 2, S2) employed sericea lespedeza (SL) supplement feeding and TST with copper oxide wire particles (COWP) based on FAMACHA score. S1 ewes/lambs …

In Vitro Investigation On Therapeutic Potential Of Juglone, A Naphthoquinone From Walnuts Against Pancreatic Cancer, Namrata Karki
LSU Doctoral Dissertations
Juglone, a naphthoquinone found in Juglandaceae family, which includes black walnut, European walnut, and butter nut possess various biological activities. The anti-cancer properties of juglone has been reported; however, the effect of juglone in pancreatic cancer (PC) has not been elucidated yet. PC is an aggressive lethal, highly metastatic disease associated with poor prognosis and high mortality rate. PC is usually diagnosed in advanced stage and chemotherapy is provided as a first line of treatment. The de novo chemoresistance that develops with chemotherapeutic treatment creates a critical need for identification of novel therapeutic agents for effectively targeting the disease. The …
Ant Diversity And Community Structure In Coastal Dunes And Wetlands, Xuan Chen
Ant Diversity And Community Structure In Coastal Dunes And Wetlands, Xuan Chen
LSU Doctoral Dissertations
How do many species live in a certain place? How does species composition changes among habitats? And what mechanisms decide species distribution? These are fundamental questions in community ecology. I first investigated ant diversity in two coastal ecosystems (dunes and wetlands) in the northern Gulf of Mexico, and then used the distribution patterns to infer assembly processes that structure ant communities in coastal areas. Specifically, the following hypotheses are tested: (1) coastal systems support lower ant diversity due to the unsuitable environment; (2) species living near the seashore are a subset of those exist near inland; (3) deterministic processes are …

Mexican Rice Borer (Eoreuma Loftini) Pheromone Trap Efficacy And Role In Invasive Species Monitoring And Pest Management, Blake Emerson Wilson
LSU Doctoral Dissertations
The Mexican rice borer, Eoreuma loftini (Dyar) (Lepidoptera: Crambidae), is an invasive pest of sugarcane, Saccharum spp.; rice, Oryza sativa; and other graminaceous crops along the U.S. Gulf Coast. Identification of E. loftini sex pheromones led to the development of pheromone baited traps. Studies were conducted to determine strategies for the use of E. loftini pheromone traps in invasive species monitoring and pest management. A two-year field study demonstrated that E. loftini pheromone traps attract males from distances of up to 100m. A behavioral assay observed that detection of the pheromone by E. loftini males occurs at ≈48m from the …

Human Norovirus In Artificial And Environmental Marine Water: Development Of Antibody Based Rapid Methods, Morgan Maite
LSU Doctoral Dissertations
Norovirus (NoV) is the principal cause of viral gastroenteritis in the United States. It has been linked to filter-feeding molluscan shellfish, that bioaccumulate the virus from contaminated surrounding waters. The consumption of raw or undercooked contaminated oysters may result in acute gastroenteritis. We investigated the occurrence of NoV GI and GII and microbial indicators of fecal contamination in oysters and harvesting water from areas along the Louisiana Gulf Coast. We developed a filtration and concentration method for the detection of NoV from oyster harvesting waters. Lastly, this body of work compares commonly used molecular techniques (RT-PCR) and a commercial enzyme …

Relationship Between Metabolic By-Products And Nervous System Failure/Fatigue, Tyler Mitchell Farney
Relationship Between Metabolic By-Products And Nervous System Failure/Fatigue, Tyler Mitchell Farney
LSU Doctoral Dissertations
Fatigue has generally been defined as an acute impairment of exercise/sport performance that includes both an increase in the perceived effort necessary to exert a desired force or power output, and the inability to produce the desired force or power output. The majority of research to date looking at fatigue has focused upon substrate utilization, however, what is relatively unknown is the contribution the nervous system has upon fatigue. Therefore, the purpose of this dissertation was to investigate potential mechanisms that relate to neural fatigue. An additional purpose was to determine if there were any relationships between metabolic by-products and …
