Variation In Personality Among Semi-Wild Myanmar Timber Elephants, Sateesh Venkatesh

Theses and Dissertations

This study examines two personality traits: exploration and neophobia, which could influence human-elephant conflicts. Thirty-one semi-wild elephants were tested over two trials using a custom novel puzzle tube containing three tasks and three rewards. Our studies show that elephants do vary significantly between individuals in both exploration and neophobia.

We must ensure that trials are scientifically, politically, and socially robust, publicly accountable, and widely transparent.

Gene drive organisms (GDOs), whose genomes have been genetically engineered to spread a desired allele through a population, have the potential to transform the way societies address a wide range of daunting public health and environmental challenges. The development, testing, and release of GDOs, however, are complex and often controversial. A key challenge is to clarify the appropriate roles of developers and others actively engaged in work with GDOs in decision-making processes, and, in particular, how to establish partnerships with relevant authorities and other …

The Fear Of Reptiles And How To Change It, Maxwell Lyman

Honors Projects

Reptile fear is prominent across many cultures. Anti-reptilian attitudes can lead to anti-conservation attitudes towards reptiles. Person-animal interaction has been shown to decrease fear desensitization and increase positive attitudes towards "unpopular" animals. My project demonstrates the effectiveness of live animal presentation in dispelling negative attitudes of reptiles. However, due to the sample size of the project, further research is highly suggested.

Hormonal Responses To Seasonal Thermal And Ecological Stressors In Japanese Macaques (Macaca Fuscata), Lilianne Nelson

Masters Theses

Relative to most primate species, Japanese macaques (Macaca fuscata) experience extreme seasonal variation in thermal and ecological stressors that can impact energetic demands. To cope with these environmental changes, levels of metabolic hormones, such as cortisol and triiodothyronine, fluctuate to facilitate energetic adjustments. While previous research in primates has investigated thermal and ecological stressors individually, a combined assessment of these stressors alongside hormone levels can provide a more holistic understanding of the relationship between a primate’s thermoregulation, energetic balance, and stress. The goals of this study were to determine the effects of season, temperature and ecological stress on …

Infection And Persistence Of Zika Virus In Female Immune-Competent Gray Short-Tailed Opossums (Monodelphis Domestica), Oscar Quintanilla

Theses and Dissertations

Zika virus (ZIKV) is a class IV RNA virus transmitted by Aedes species of mosquitoes. It produces flu-like symptoms, but recent studies have associated additional, more severe pathologies with ZIKV like microcephaly. Currently, no effective treatment options or vaccines exist. This is partly due to limitations of current animal models. Monodelphis domestica (the gray short-tail opossum) may serve as a proper model for ZIKV research. Here we test the susceptibility of M. domestica to ZIKV infection. Female, immune-competent subjects were injected with live ZIKV and analyzed serologically and histologically for evidence of ZIKV replication. ELISAs performed on sera confirmed that …

Fall Field Report, August-November 2020, W. Ross Silcock

Nebraska Bird Review

Two issues were of concern this fall, and both appeared to have consequences or at least similarities in Nebraska. A major die-off in New Mexico made national news: https://www.aba.org/the-data-behind-mysterious-bird-deaths-in-new-mexico/. On Sep 9, 2020, the temperature dropped from 96°F to 40°F in the Albuquerque area, a record low, winds reached 70 mph, and several inches of snow fell, killing large numbers of birds directly. Over the next few days, hundreds more dead birds were picked up. Some have linked this high mortality to birds displaced from the mountains due to fire and unfortunately being caught in the severe weather. While fire …

History Of The Seward-Branched Oak Lake Christmas Bird Count, 1993-2020, Joseph A. Gubanyi

Nebraska Bird Review

The Seward-Branched Oak Lake Christmas Bird Count (Seward-BOL CBC) began in 1993 and has been conducted every year since then except for 2010 for a total of 27 counts. Weather conditions prevented the count on the selected date in 2010 and a backup date could not be set up. The count was started for several reasons. The area west of Lincoln has a diversity of habitats including all or part of four public lakes (Branched Oak, Pawnee, Twin Lakes, and Meadowlark) as well as a diversity of terrestrial habitats on both public and private land. The circle is close to …

Summer Foraging Range And Diurnal Roost Selection Of Tri-Colored Bats, Perimyotis Subflavus., Dustin Bradley Thames

Masters Theses

Tri-colored bat populations are declining in eastern North America where the fungal pathogen Pseudogymnoascus destructans has been introduced. The pathogen causes disease and mortality in cave hibernating bats. Once considered a common species in Tennessee, tri-colored bats are now being considered for protection under the Endangered Species Act. There is a paucity of research examining the basic ecology of tri-colored bats. Research to fill these knowledge gaps is needed to inform conservation plans and to define critical habitat. The first objective of my research was to characterize the summer diurnal roosts of tri-colored bats and to examine roost selection at …

Effects Of Temporal Variation On Ambient Light In Northwest Arkansas, Ashlyn Anderson

Biological Sciences Undergraduate Honors Theses

An animal’s life success is determined solely by its fitness, which makes choosing a mate one of its most important life decisions. Natural selection plays a big part in an animal’s phenotype, but so does sexual selection. Even though females are usually thought to be the choosier sex, in many species or seasons males are also choosy. Male mate preference is an understudied topic compared to female mate preference and therefore, even less is known about the outcomes of a male’s prior mating experience’s influence on future mating experiences. Therefore, I dove deeper into this topic with the highly studied …

Larval Fish Sampling And Scaphirhynchus Sturgeon Drift Dynamics In The Mississippi And Missouri Rivers, Hae Hyun Kim

MSU Graduate Theses

Humans have been altering the natural ecosystem for centuries. These alterations provide many socioeconomic benefits (e.g., navigation and flood-control). However, these alterations can have negative ecological consequences. Large rivers across the country have been manipulated to facilitate various human activities. Rivers are dynamic systems governed by various abiotic and biotic factors. Ultimately these alterations change the natural biogeochemical cycles and reduce available habitats. These impacts likely affect riverine fishes’ ability to carry out their lifecycle. Riverine organisms, and particularly fish, have adapted to survive in free-flowing systems. Population dynamics (i.e., recruitment, growth and mortality) are the basis of fisheries management. …

Linking Mosquito Surveillance To Dengue Fever Through Bayesian Mechanistic Modeling, Clinton B. Leach, Jennifer A. Hoeting, Kim M. Pepin, Alvaro E. Eiras, Mevin B. Hooten, Colleen T. Webb

USDA Wildlife Services: Staff Publications

Our ability to effectively prevent the transmission of the dengue virus through targeted control of its vector, Aedes aegypti, depends critically on our understanding of the link between mosquito abundance and human disease risk. Mosquito and clinical surveillance data are widely collected, but linking them requires a modeling framework that accounts for the complex non-linear mechanisms involved in transmission. Most critical are the bottleneck in transmission imposed by mosquito lifespan relative to the virus’ extrinsic incubation period, and the dynamics of human immunity. We developed a differential equation model of dengue transmission and embedded it in a Bayesian hierarchical …

Revision Of Genus-Group Taxa In The Family Scorpiopidae Kraepelin, 1905, With Description Of 15 New Species (Arachnida: Scorpiones), František Kovařík, Graeme Lowe, Mark Stockmann, František Šťáhlavský

Euscorpius

The scorpiopids comprise a large scorpion family, distributed widely across the Oriental region, that currently encompasses 82 species placed under 8 genera and one subgenus. A variety of morphological characters have been used in the diagnoses of these genera or subgenera. Some characters were introduced by Vachon (1980) and Soleglad & Sissom (2001) when less than a few dozen species were known, while other more recent characters have not been fully evaluated. We critically review all characters that have been applied to generic or subgeneric taxonomy of the family, as well as several others hitherto neglected. We analyze their variation …

Effect Of Seasons And Scorpion Size On The Foraging And Diet Of The Striped Bark Scorpion, Centruroides Vittatus (Buthidae: Scorpiones) In Blackbrush Habitat Of South Texas, C. Neal Mcreynolds

Euscorpius

Diet and foraging success of the striped bark scorpion, Centruroides vittatus, in South Texas are influenced by both scorpion size and season of the year. In the ten-year study of the striped bark scorpions in the blackbrush habitat of south Texas, the diet was variable with caterpillars (Lepidoptera) as the main prey for all seasons and all size classes of scorpions. The proportion of caterpillars did vary significantly with size class of scorpion and months of the year with intermediate size scorpions capturing more caterpillars during January–April than other size classes or months of the year. The proportion of …

Connections In The Underworld: A Morphological And Molecular Study Of Diversity And Connectivity Among Anchialine Shrimp., Robert Eugene Ditter

FIU Electronic Theses and Dissertations

This research investigates the distribution and population structure of crustaceans, endemic to anchialine systems in the tropical western Atlantic focusing on cave-dwelling shrimp from the family Barbouriidae. Taxonomic and molecular tools (genetic and genomic) are utilized to examine population dynamics and the presence of phenotypic hypervariation (PhyV) of the critically endangered species Barbouria cubensis (von Martens, 1872). The presence of PhyV and its geographic distribution is investigated among anchialine populations of B. cubensis from 34 sites on Abaco, Eleuthera, and San Salvador, Bahamas. Examination of 54 informative morphological characters revealed PhyV present in nearly 90% (n=463) of specimens with no …

Mathematics, Physics, and Computer Science Faculty Articles and Research

Undocumented historical losses of sea turtle nesting beaches worldwide could overestimate the successes of conservation measures and misrepresent the actual status of the sea turtle population. In addition, the suitability of many sea turtle nesting sites continues to decline even without in-depth scientific studies of the extent of losses and impacts to the population. In this study, multidecadal changes in the outlines and area of Jana and Karan islands, major sea turtle nesting sites in the Arabian Gulf, were compared using available Kodak aerographic images, USGS EROS Declassified satellite imagery, and ESRI satellite images. A decrease of 5.1% and 1.7% …
