The Biofiltration Ability Of Asparagus Densiflorus To Remove Sulfur Dioxide From The Indoor Atmosphere, Rhiannon De La Rosa, Mary Savin

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Sulfur dioxide is an inorganic compound (IC) and air pollutant that causes health risks in humans. The buildup of sulfur dioxide (SO2) in enclosed indoor spaces is, therefore, a concern to human health, especially since the average person spends 90% of his/her time indoors. This study focused on decreasing SO2 concentration in a cost-effective and simple way—by using botanical biofiltration, or the uptake of pollutants by plants. Research in biofiltration has focused mostly on the remediation of volatile organic compounds (VOC). However, research has also shown that plant species that remediate VOC efficiently also have the potential for efficient IC …

Vertical‑Surface Navigation In The Neotropical Whip Spider Paraphrynus Laevifrons (Arachnida: Amblypygi), Patrick Casto, Daniel D. Wiegmann, Vincent J. Coppola, Daniele Nardi, Eileen A. Hebets, Verner P. Bingman

Eileen Hebets Publications

Studies on whip spider navigation have focused on their ability to locate goal locations in the horizontal plane (e.g., when moving along the ground). However, many species of tropical whip spiders reside and move along surfaces in the vertical plane (e.g., trees). Under controlled laboratory conditions, the current study investigated the ability of the tropical whip spider, Paraphrynus laevifrons, to return to a home shelter on a vertical surface in the presence of numerous, similar, and competing refuge sites, as well as the distribution of navigational errors in the vertical, horizontal, and diagonal plane. We also assessed the relative …

Impacts Of Driving Factors On Annual Cicada Emergence In Relation To The Seasonal Abundance Of Eastern Copperheads (Agkistrodon Contortrix), Jesse Christian Sockman

Online Theses and Dissertations

For many species, life history events are cyclical and often correspond to specific environmental conditions. As a result of environmental variability, the optimal conditions that regulate the range and activity of highly regulated cyclical organisms, like cicadas, are subject to temporal change. Variability in cicada emergence and abundance has been shown to impact the species that rely on the rapid influx of nutrients. One such predator is the Eastern Copperhead (Agkistrodon contortrix) that has been noted feeding on emerging cicadas throughout their range. In eastern Kentucky, observations of copperheads congregating to feed on cicadas has been documented in recreational areas. …

Insights Into The Feeding Behaviors And Biomechanics Of Varroa Destructor Mites On Honey Bee Pupae Using Electropenetrography And Histology, Andrew Y. Li, Steven C. Cook, Daniel E. Sonenshine, Francisco Pasada-Florez, Noble I.I. Noble, Joseph Mowery, Conner J. Gulbronson, Gary R. Bauchan

Biological Sciences Faculty Publications

Feeding behaviors and biomechanics of female Varroa destructor mites are revealed from AC-DC electropenetrography (EPG) recordings of mites feeding from Apis mellifera honey bee pupae and histology of mite internal ingestion apparatus. EPG signals characteristic of arthropod suction feeding (ingestion) were identified for mites that fed on pupae during overnight recordings. Ingestion by these mites was confirmed afterwards by observing internally fluorescent microbeads previously injected into their hosts. Micrographs of internal ingestion apparatus illustrate the connection between a gnathosomal tube and a pharyngeal lumen, which is surrounded by alternating dilator and constrictor muscles. Inspection of EPG signals showed the muscularized …

Drivers Of Ant Composition, Richness, And Trophic Guilds In Neotropical Iron Ore Cavities, Rodrigo A. Castro-Souza, Thais G. Pellegrini, Marconi Souza-Silva, Rodrigo L. Ferreira

International Journal of Speleology

Subterranean habitats may be considered limiting for animal colonization, especially for ants, due to permanent darkness and mainly because of oligotrophic conditions. While not as deep as limestone caves, iron ore caves and other subterranean habitats may be more available for colonization because of their shallower depth. We use the richness and composition of ants to assess how differences in habitat structure affect the biodiversity and ecosystem function between cavities and surrounding epigean landscapes. We predicted that the distribution of ants would be different because of the variation in habitat structure and cavity conditions may act as a filter for …

All Peer-Reviewed Publications

Pig production is one of the fastest growing livestock sectors. Development of this sector is hampered by rapidly increasing costs of fishmeal (FM), which is a common protein source in animal feeds. Here, we explored the potential of substituting FM with black soldier fly larval meal (BSFLM) on growth and blood parameters of pigs as well as economic aspects. At weaning, 40 hybrid pigs, i.e., crossbreeds of purebred Large White and Landrace were randomly assigned to five iso-nitrogenous and iso-energetic dietary treatments: Control (0% BSFLM and 100% FM (T0)), and FM replaced at 25% (T25), 50% (T50), 75% (T75) and …

Background: Tsetse flies (Glossina sp.) are the vectors of human and animal trypanosomiasis throughout sub-Saharan Africa. Tsetse flies are distinguished from other Diptera by unique adaptations, including lactation and the birthing of live young (obligate viviparity), a vertebrate blood-specific diet by both sexes, and obligate bacterial symbiosis. This work describes the comparative analysis of six Glossina genomes representing three sub-genera: Morsitans (G. morsitans morsitans, G. pallidipes, G. austeni), Palpalis (G. palpalis, G. fuscipes), and Fusca (G. brevipalpis) which represent different habitats, host preferences, and vectorial capacity. Results: Genomic analyses validate established evolutionary relationships and sub-genera. Syntenic analysis of Glossina relative …

Experimental Feeding Studies With Crickets And Locusts On The Use Of Feed Mixtures Composed Of Storable Feed Materials Commonly Used In Livestock Production, P. Straub, C. M. Tanga, I. Osuga, W. Windisch, S. Subramanian

All Peer-Reviewed Publications

Insects such as the Mediterranean field cricket, Gryllus bimaculatus and the Desert locust, Schistocerca gregaria, are emerging as potential sources of human food and feed for livestock. High nutritive value and efficient feed conversion make them attractive for commercial production as novel livestock, but these properties strongly vary with the insects´ diet. Current mass-rearing protocols are based on fresh, non-storable feed materials. This requires constant supply and makes the systems sensitive to fluctuations regarding nutritional quality and safety. Hence there is a need to find storable, readily available feeds. Therefore, experimental diets were composed from the five different feed materials, …

Species-Area Model Predicting Diversity Loss In An Artificially Flooded Cave In Brazil, Rodrigo L. Ferreira, Thais G. Pellegrini

International Journal of Speleology

Subterranean environments are poorly known regarding many ecological aspects, such as community structure and its response to different disturbances. To estimate the effects of ground area lost in a limestone cave community in Southeastern Brazil, the invertebrate fauna was sampled before 76% of the cave floor was submerged by the filling of a hydroeletric power plant reservoir. Then, a 2-year monitoring was conducted. A species-area curve based on empiric data was constructed and the z-value of the species-area equation was calculated, what allowed estimating the expected cave richness after flooding comparing with data obtained during the monitoring. The results support …

Trade-Offs Shape Carotenoid-Based Color Variation In Redheaded Pine Sawfly (Neodiprion Lecontei) Larvae, Maranda Gaines

Lewis Honors College Capstone Collection

Carotenoids serve various ecological roles in animals including coloration, immune responses, and vision. Carotenoid-derived coloration is greatly emphasized in the literature, particularly relating to mate choice and aposematic warning. However, the trade-offs between the color and non-color functions of carotenoids are not thoroughly explored. In the redheaded pine sawfly (Neodiprion lecontei), some larval populations have yellow pigmentation, using carotenoids derived from their diets for aposematic warning coloration. Other larval populations are white in color, having genetically lost the ability to produce the yellow pigment. Because carotenoids are essential to life functions in both the yellow and white populations, we aim …

Greenhouse Aquaponics: Custom Aquaponic Systems At Home, Jesse L. Blanchard, David G. Hyatt, Jennie Popp, Leah English

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Taking advantage of inherent natural systems, aquaponic practices hold the potential to serve as an educational, sustainable, and profitable hobby for home gardeners facing common constraints such as temperature, space, and pests. The goal of this research was to assess the feasibility of implementing a small scale (4,542-liter) home -based aquaponic system in a small (48.768 square meter) greenhouse to produce fresh produce and fish protein. System construction and maintenance costs were compared to the value of crops and fish produced to determine whether this aquaponic system is a feasible option for the home grower. It was hypothesized that this …

Geospatial Analysis Of Rickettsial Species In Arkansas, Amy D. Frank, Ashley P.G. Dowling

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Rickettsia species are obligate intracellular, arthropod-borne bacteria with a potential to cause multiple diseases including Rocky Mountain spotted fever (RMSF). Fleas, mites, and ticks serve as vectors for Rickettsia, but ticks are the primary vector of interest. RMSF and other rickettsial diseases have continued to gain importance in both human and veterinary medicine as RMSF is the most common tick-borne disease within the United States according to the Lyme and Tick-Borne Disease Research Center. A statewide citizen science project was utilized to determine the prevalence of Spotted Fever Group (SFG) Rickettsia in Arkansas. This project yielded results in 64 …

Impact Of Selected Infrared Wavelengths On Inactivation Of Microbes On Rough Rice, Rebecca L. Bowie, Griffiths Atungulu, Abass Oduola, Shantae Wilson, Zeinab Mohammadi-Shad

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Formation of harmful microbes and their associated mycotoxins on rough rice during storage presents negative socioeconomic impacts to producers and consumers. The objective for this study was to investigate the impact of treating rough rice with selected infrared (IR) wavelengths at different IR intensities and heating durations, followed by a tempering step for further inactivation of microbes (mold and bacteria) on the grain. Freshly-harvested long-grain, hybrid, rough rice (XL 745) with initial moisture content (IMC) of 18.4% wet basis (w.b.) was used. Two-hundred grams (200 g) samples of rice were treated at different IR wavelengths (λ), 3.2, 4.5, and 5.8 …

Master's Theses or Doctor of Nursing Practice

Working with other graduate students on a grant given to Fort Hays State University, from the Kansas Department of Wildlife, Parks and Tourism, I looked at presence and species of ectoparasites on bat species. The main goal of our grant was to quantify and qualify the status of the northern myotis (Myotis septentrionalis) in the state of Kansas, and to record data on any bycatch. I worked on our grant in the summer field seasons of 2016 and 2017, May to October, as described by the Indiana bat protocol.

Bats were captured by using mist nets set over …

Ecophysiological Determinants Of Sexual Size Dimorphism: Integrating Growth Trajectories, Environmental Conditions, And Metabolic Rates, Marie-Claire Chelini, John P. Delong, Eileen A. Hebets

Eileen Hebets Publications

Sexual size dimorphism (SSD) often results in dramatic differences in body size between females and males. Despite its ecological importance, little is known about the relationship between developmental, physiological, and energetic mechanisms underlying SSD. We take an integrative approach to understand the relationship between developmental trajectories, metabolism, and environmental conditions resulting in extreme female-biased SSD in the crab spider Mecaphesa celer (Thomisidae). We tested for sexual differences in growth trajectories, as well as in the energetics of growth, hypothesizing that female M. celer have lower metabolic rates than males or higher energy assimilation. We also hypothesized that the environment in …

Perception And Awareness Of Insects As An Alternative Protein Source Among Fish Farmers And Fish Feed Traders, G. Ssepuuya, C. Sebatta, E. Sikahwa, P. Fuuna, M. Sengendo, J. Mugisha, K. K.M. Fiaboe, D. Nakimbugwe

All Peer-Reviewed Publications

The perception of key players in the fish farming sector towards the use of insects is important for their acceptance to adopt insects as an alternative protein source to the expensive fish meal. Perception was established through a cross-sectional study of 208 fish farmers and 71 fish feed traders and/or processors conducted in Gulu, Tororo and Masaka districts in Uganda, using descriptive, Chi-square, correlation and factor statistical analysis of the data collected. Males dominated the fish farming and fish feed trading and/or processing enterprises. Youths were involved to almost the same extent as adults. Fish farmers majorly practiced pond fish …

Development Of A Remotely Activated Field Sprayer And Evaluation Of Temperature And Aeration On The Longevity Of Steinernema Riobrave Entomopathogenic Nematodes For Treatment Of Cattle Fever Tick-Infested Nilgai, John A. Goolsby, Diana Cantu, Alejandro Vasquez, Alexis Racelis

School of Integrative Biological & Chemical Sciences (Formerly Dept. of Biology)

A remotely activated field sprayer was developed for application of the entomopathogenic nematode, Steinernema riobrave (Cabanillas, Poinar, and Raulston) for eradication of the southern cattle fever tick, Rhipicephalus microplus (Canestrini) infesting free-ranging nilgai (Boselaphus tragocamelus) in South Texas. The battery powered sprayer is activated by sonic sensors that detect movement of nilgai through fence crossings. An onboard computer operates the sprayer pump and aerator that oxygenates the solution of nematodes. Several types of aeriation, agitation, and cooling were tested to prolong the viability of the nematodes in water. Continuous aeration extended the longevity of S. riobrave to more than two …
