Vibratory Noise Impacts The Sensory Ecology Of A Funnel-Weaving Spider, Brandi June Pessman

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Animals experience their world through diverse sensory systems, leveraging information from prey, predators, and potential mates to inform behavioral decisions. Environmental noise disrupts information via spectral or amplitude masking, degradation, or distortion, potentially leading to costly errors in responses. Critically, urbanization has accelerated the proliferation of novel noise sources, triggering significant shifts in communication, foraging, and predator-prey dynamics among urban wildlife. While vertebrate studies have illuminated urban animals’ flexibility to anthropogenic acoustic noise, a comprehensive understanding requires broader investigations across diverse animal taxa and sensory modalities. To address these gaps, my dissertation explored the impacts of anthropogenic substrate-borne (vibratory) noise …

An Examination Of The Eastern Nebraska And Western Iowa Flash Flood Event Of 6-7 August 1999, Catherine M. Zapotocny

National Oceanographic and Atmospheric Administration: Technical Reports and Related Materials

Flash flooding occurs each summer in eastern Nebraska and western Iowa. While 10-inch rains are extraordinary, it is not uncommon to have at least one excessive rain event during the annual convective season. A significant flash flood occurred in east central Nebraska and western Iowa the night of August 6, 1999 into the morning of August 7, 1999. Antecedent hydrologic conditions limited the loss of life, however considerable property damage resulted as the heavy rain fell over the urbanized areas in eastern Nebraska and western Iowa.

Several flash flood ingredients came together over the area. These meteorological factors are typical …

Anuran Diversity And Abundance Across Two Sites With Varying Levels Of Light Pollution In El Valle De Antón, Coclé, Panamá, Jackson Dray

Independent Study Project (ISP) Collection

The impact of artificial light at night (ALAN) on anuran populations has been a subject of growing concern in ecological research. Anurans are particularly susceptible to the impacts of artificial light due to their nocturnal nature and an extensive exposure throughout various stages of life histories. Exposure to artificial light has been shown to impact the larval development and reproductive behavior of anurans. The impacts on anurans juvenile populations suggest a relationship between light pollution and anuran abundance. This study aimed to investigate the hypothesis that ALAN negatively affects the abundance and diversity of anurans. Field surveys were conducted in …

Independent Study Project (ISP) Collection

Forest fragmentation and increasing agricultural land use are posing threats to the diversity of vertebrates in Panama and across the Mesoamerican Biological Corridor. Protected areas are crucial for providing connectivity and maintaining vertebrate populations. For endemic species with small native ranges, these protected areas are critical for their survival due to sensitivity of habitat change. Higher species diversity and occupancy has been reported for both birds and mammals in protected and forested areas. This pilot survey of vertebrate species was conducted to determine which species live in a primary forest within the buffer zone of La Amistad International Park near …

Necked Keelback Fowlea Schnurrenbergeri (Kramer, 1977) In Northeastern Punjab, Pakistan, Mudassar Basri, Zohaib Nasar

Journal of Bioresource Management

The bar-necked keelback snake plays a vital ecological role as a natural pest controller, effectively regulating populations of fish, frogs, and rodents. Through their predatory behavior, they contribute significantly to maintaining ecological balance by managing the numbers of these smaller creatures, thereby contributing to the overall health of ecosystem. We have documented Fowlea schnurrenbergeri in the urban center of Tehsil Zafarwal and Dariyapur village, within Narowal district, Punjab. Previously, Sindh-Thatta represented the southeastern most known locality for this species in Pakistan. This study presents new insights into the distribution range of this less-frequently observed species.

Effectiveness Of Frog Skin Secretions Against Uv-B Radiation, Connor Mcgaha, Kinkade Mcmurray, Lee B. Kats

Seaver College Research And Scholarly Achievement Symposium

As an increasing number of their species face possible extinction, amphibian populations have been steadily declining over the past decades (IUCN). While various factors have been suggested or proven to be partially responsible for this reduction, increased ultraviolet B radiation (UVBR) appears to be one of the more prominent explanations, especially when considering the continual thinning of the Earth’s ozone layer due to anthropogenic climate change. However, it has also been discovered that skin secretions, which are reported to function as a component of amphibians’ innate immune systems, may have an effect on UVBR (Cramp and Franklin). With this in …

A Dietary Variety: Analyzing The Impacts Of Diverse Vs Worm-Exclusive Diets On The Blanding’S Turtle (Emydoidea Blandingii), Caitlin F. Copenhaver

Honors Program: Senior Projects (Public)

The endangered Blanding’s turtle (Emydoidea blandingii) is a species with a generally diverse diet in their freshwater wetland habitats; they consume prey such as crayfish and snails. In captivity, these options often become more limited due to logistical reasons. As ex situ conservation efforts such as captive rearing and head-starting are becoming more popular for this species, it will be important to gain more insight on how these more limited diets might affect these turtles. This study describes a comparison between diets in six captive Blanding’s turtles from September to November of 2023, with three turtles receiving only …

Avian Symbionts Of Sulawesi: Identifying And Correlating Malaria Parasites And The Microbiome In Communities Of Endemic Avian Hosts, Rachael Joakim

Dissertations, Theses, and Capstone Projects

Since the evolution of complex organisms, there have been communities of symbionts inhabiting them. Thanks to the development of parallel sequencing techniques, DNA of entire microbial communities can be sequenced from a single sample. Some microbes can be parasitic in nature, such as Haemosporida, an order of eukaryotes causing malaria. While most symbionts form a more commensal host relationship in wild systems, host-symbiont dynamics can vary in pathogenicity based on biotic and abiotic factors. In vertebrates, microbial communities in the gut play a major role in host function, including immune responses to Haemosporida. Though this relationship is most commonly explored …

Animal Conservation In St. Louis, Kate O'Sullivan

Undergraduate Research Symposium

St. Louis has a multitude of organizations involved in the natural sciences. But how many of them actually contribute towards animal conservation? The St. Louis Zoo is an organization that focuses a lot of its effort on presentation, so how does that impact the funds that go towards actually saving the animals? I plan to dive into the different animal-based organizations in St. Louis and its surrounding areas, as well as discuss the positives and negatives of each organization. Furthermore, I will provide examples from several sources that I have been reviewing all year to support my claims. I plan …

A Survey Of Proximal Sensilla Associated With Denticle Subrows On Scorpion Pedipalp Fingers (Arachnida: Scorpiones), With Observations On Scorpion Fluorescence, Graeme Lowe, Victor Fet

Euscorpius

Sensilla on the dentate margins of scorpion pedipalp fingers, associated with denticle subrows or terminal denticles, were surveyed by white light, UV fluorescence and scanning electron microscopy. A total of 163 species belonging to 103 genera from 19 families were examined, representing all major phylogenetic lineages in the order. In the majority of species (141/152) with dentition organized into linear subrows of median denticles, a small socketed sensillum with a short shaft was observed at the proximal terminus of each subrow, termed a ‘subrow proximal sensilla’ (SPS). With few exceptions, SPS were non-fluorescent (‘Type N’) in buthids, and fluorescent (‘Type …

Patterns Of Genetic Structure In Spiders Beetles, Naiya Sims

Mahurin Honors College Capstone Experience/Thesis Projects

Spider beetles are a poorly known group of North American beetles in the family Ptinidae. Protection of biodiversity requires knowledge of species- and population-level distinctiveness, so data regarding genetic structure of spider beetles can shed light on conservation priorities. Spider beetles in the genus, Coleotestudus, are distributed broadly in the southwestern US. Given their small size and lack of flight, it is presumed that the dispersal capability of Coleotestudus is limited, leading to strong population structure on a small spatial scale. We used a three-enzyme restriction-site-associated DNA sequencing (3RAD) strategy to identify single nucleotide polymorphisms (SNPs) throughout the genome …

Environmental Biology Masters Capstone, Antonio Gonzalez-Pita

Regis University Student Publications (comprehensive collection)

Human wildlife interactions (HWI) pose a complex challenge for wildlife managers. Human encroachment into wildlife habitat and the growing number of outdoor recreationists are increasing the frequency of contact and conflict, especially in regions such as the Front Range of Colorado. Geographic information systems (GIS), which use a combination of remote sensing and environmental survey data, allow for predictive spatial analyses of where human wildlife interactions are likely to occur. I used publicly reported observations of moose to create spatial predictive maps in a species distribution model framework. Slope and elevation were shown to be the strongest predictors of HWI, …

The Morphological Evolution Of The Inner Ear In Lacertoidea (Squamata), Cristian Hernandez

Biology Dissertations - Archive

The popularization of high-resolution computed tomography(HRCT) has produced a revolution in the field of comparative anatomy. This technology allows us to reach a level of morphological detail in our observations that has never been possible previously. Now we can perform digital dissections isolating structures of interest such as individual bones, soft tissue organs, and even generate 3D models of body cavities (endocasts) such as the braincase and inner ear. Encompassed with the progress of the HRCT, 3D geometric morphometrics have emerged as a common tool to address morphological questions in a statistical context that outperforms the traditional 2D geometric morphometrics. …

Investigating The Relationships Between Biotic And Abiotic Factors Affecting Migratory Behavior In Westslope Cutthroat Trout Within The Priest River System, Kyle M. Keenan

EWU Masters Thesis Collection

Numerous salmonid species demonstrate diverse life histories, encompassing both resident and migratory behaviors. Migratory life histories play a pivotal role in maintaining metapopulations for various reasons, facilitating genetic exchange between populations and yielding larger-sized females with increased fecundity relative to residents. This study took place in northern Idaho, within the lower Priest River system, which is highly susceptible to degrading habitat. Previous research has discovered this system as a significant contributor to migratory Westslope Cutthroat Trout (Oncorhynchus lewisi, WCT) in the Lake Pend Oreille and Priest River systems. Expanding on these results, we compared four Priest River tributaries that produced …
