A Remote Sensing Approach To Assess The Historical Invasion Of Phragmites Australis In A Brackish Coastal Marsh, Jason S. Hagani, John Y. Takekawa, Steven C. Chappell, Richelle L. Tanner, Adrienne R. Ernst, Karin M. Kettenring

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Introduction: Coastal estuarine wetlands provide important habitats for a variety of endemic flora and fauna but are particularly vulnerable to biological invasions. Regular monitoring of changes in these vulnerable wetlands has become increasingly important for effective management, especially considering threats from climate change effects and human disturbance. Historical analyzes of plant invasions may guide targeted management strategies to eradicate harmful species. Estimating the distribution of invasive species has never been more accessible with the improved availability of high-resolution data and innovations in remote sensing, estimating the distribution of invasive species has never been more accessible.

Methods: We assessed the spread …

Modeling Stocking Suitability At Lake Mcconaughy To Improve Initial Survival Of Stocked Walleye (Sander Vitreus) And White Bass (Morone Chrysops), Sean M. Farrier

Biology Theses, Dissertations, and Student Creative Activity

Fish stocking continues to be an important and often-used tool in fisheries management. However, hatchery resources are often limited by funding and space. Therefore, survival of stocked fish is important to improve efficiencies and support important fisheries resources. Various strategies to improve survival have been examined over time, whether in the hatchery or in the waterbody. To improve stocking efficiency, managers should consider potential bottlenecks that could limit the survival of stocked products. To date, previous studies that have considered stocking in relation to these bottlenecks have only considered single factors at one time; however, multiple bottlenecks may be acting …

First Report Of Regeneration In The Genus Mesobuthus (Scorpiones: Buthidae), Rıdvan Kurt, Ersen A. Yağmur, Gülhanım Çelik

Euscorpius

A new example of scorpion leg regeneration is reported in an adult male Mesobuthus mesopotamicus (Penther, 1912). A claw (pretarsus) was observed to regenerate at the distal end of the tibia of the left leg II. The regeneration case is described and illustrated.

Relative Genetic Homogeneity Within A Phenotypically Diverse Group; A Case Of The Lake Tana Labeobarbus (Cyprinidae) Species Flock, Ethiopia, Kebede Beshera

Faculty Publications

The Lake Tana Labeobarbus species flock represents one of the world’s most famous examples of lacustrine species radiations. Previous studies of this group have resulted in the description of at least 15 species based on their differences in functional morphology and definition of two clades (lacustrine and riverine spawning clades) based on life history traits. A total of 166 fish representing 14 Labeobarbus species were genotyped using 10 lineage-specific hexaploid microsatellite loci. Six of these loci were developed for this study based on DNA sequence contigs derived from a microsatellite-enriched genomic library of Labeobarbus intermedius from Lake Tana; the remaining …

Phylogeography Of The Pacific Sardine, Sardinops Sagax, In The Northeastern Pacific, Ella Adams

Theses

The Pacific Sardine, (Sardinops sagax), is a small, coastal pelagic species in the family Clupeidae. Sardine are an ecologically important forage fish for many animals, including larger, economically and ecologically important fishes, and have historically supported an important commercial fishery. When the fishery declined in the 1940s, a massive effort in understanding population structure for the Pacific Sardine resulted in a wealth of literature. Initially, these studies agreed on a large panmictic population with high annual variation, but the general consensus has since been that there are multiple subpopulations of the Pacific Sardine along the West Coast of …

Social Tolerance, Cooperation, And Constraint Shape Differentiated Social Relationships In Female Chimpanzees, Stephanie A. Fox

Anthropology ETDs

In this dissertation, I investigate variables that promote and constrain female-female social relationships in chimpanzees, a species where females disperse at sexual maturity, reside primarily among non-kin as adults, and where fission fusion social structure can reveal how female social behavior responds to different social contexts. I conducted my research using a combination of detailed behavioural data that I collected during a one-year field season (2019-2020) and long-term data (2010-2019) collected by the Kibale Chimpanzee Project. I show that female chimpanzees form stable, differentiated social relationships, which reflect active preferences and variation in social tolerance (Chapter 2); females leverage these …

Broad Host Susceptibility Of North American Amphibian Species To Batrachochytrium Salamandrivorans Suggests High Invasion Potential And Biodiversity Risk, Matthew J. Gray, Edward Davis Carter, Jonah Piovia-Scott, J. Patrick W. Cusaac, Anna C. Peterson, Ross D. Whetstone, Andreas Hertz, Aura Y. Muniz-Torres, Molly C. Bletz, Douglas C. Woodhams, John M. Romansic, William B. Sutton, Wesley Sheley, Allan Pessier, Catherine D. Mccusker, Mark Q. Wilber, Debra L. Miller

Agricultural and Environmental Sciences Faculty Research

Batrachochytrium salamandrivorans (Bsal) is a fungal pathogen of amphibians that is emerging in Europe and could be introduced to North America through international trade or other pathways. To evaluate the risk of Bsal invasion to amphibian biodiversity, we performed dose-response experiments on 35 North American species from 10 families, including larvae from five species. We discovered that Bsal caused infection in 74% and mortality in 35% of species tested. Both salamanders and frogs became infected and developed Bsal chytridiomycosis. Based on our host susceptibility results, environmental suitability conditions for Bsal, and geographic ranges of salamanders in the …

Geoarchaeology Of Estuarine Seascapes In Tampa Bay, Florida., Kendal R. Jackson

USF Tampa Graduate Theses and Dissertations

This dissertation investigates the geological, ecological, and archaeological histories of Tampa Bay, Florida’s largest open-water estuary system. Previous geoscientific and archaeological work has studied the evolution of Florida’s estuaries as ‘pre-anthropogenic’ ecosystems and conceptualized Indigenous maritime societies as mostly passive inhabitants of dynamic ‘natural’ environments. Further, the environmental legacies of more recent, industrial-scale estuary modification attending Florida’s 20th-century population boom have been understudied—leading to popular and scientific confusion about historical conditions. The work composing this dissertation research seeks to reconceptualize Tampa Bay as a complex mosaic of cultural seascapes that have been variously altered and modified by human societies across …

Machine Kinship: The Impossible Duet, Diana Sanchez

Masters Theses

Machine Kinship: The impossible duet What does it mean to vanish from earth when you are the last of your kind? In 1987 the Kauai OO was recorded singing his final song. It was meant to be a duet, but as the last of his kind his song hangs in the air, unanswered. The other half of the duet is forever lost. Built to sing at dawn, birds must wake up earlier to hear each other before human chaos interferes. So here, it is always almost sunrise. As a parallel past-future response, the last birdsong was fed into a machine …

Fluidity And Inconstancy: Australian Bush Tomatoes As An Exemplar Of Non-Normative Sex Expression, Christopher T. Martine

Faculty Journal Articles

Solanum, a genus of ~1500 global species, is one of the more interesting plant groups in which to study reproductive biology and ecology. Overwhelmingly, species in this group express full cosexuality, where individual plants have flowers containing both fully-functioning “male” (staminate) and “female” (carpellate) organs. However, there have been multiple and widespread evolutionary transitions within the genus to non-normative variations on this ancestral condition. Australian bush tomatoes (ca. 40 species) are especially diverse in this regard, with uncommon variation and combinations of unisexuality and cosexuality -- including, most notably, two sexual systems known as dioecy (unisexual male or female …

A Review Of Theropithecus Oswaldi With The Proposal Of A New Subspecies, Dagmawit Abebe Getahun, Eric Delson, Chalachew Mesfin Seyoum

Publications and Research

Theropithecus oswaldi darti, as currently understood, is the oldest Theropithecus taxon in the fossil record and the earliest subspecies in the Theropithecus oswaldi lineage. Theropithecus oswaldi darti is typified at the site of Makapansgat in South Africa, and a similar form (T. o. cf. darti) is usually recognized at Hadar, Dikika, some Middle Awash localities, and Woranso-Mille in Ethiopia. This taxon is also tentatively believed to occur in Kenya at Kanam and Koobi Fora and in Member C of the Shungura Formation in Ethiopia. While there is a general consensus that the East African ‘darti’ specimens are …

Movement Patterns Of Two Bat Species Active During Winter In The Southeastern United States, Reilly T. Jackson, Emma V. Wilcox, Riley F. Bernard

Biological Sciences Faculty Publications and Presentations

During winter in the southeastern United States, cavernicolous bats, many species of which are susceptible to white-nose syndrome, periodically arouse from torpor and occasionally leave hibernacula. We investigated the winter movements and habitat use of two bat species persisting during the white-nose syndrome epizootic: the gray bat Myotis grisescens and the eastern small-footed bat Myotis leibii. We deployed very-high-frequency radio transmitters on individual bats captured outside hibernacula to investigate activity, which may include foraging, during winter. We tracked bats from release at the cave entrance until their transmitter signal was lost or they remained stationary for 15 min or …

Dietary Parental Effects In A Generalist Heribivore, Emma J. Sellers

Undergraduate Theses, Capstones, and Recitals

The environment or experiences of a parent generation can impact the fitness of the next generation, a phenomenon known as parental effects. The parental diet, for example, can have consequences for their offspring who may perform better or worse on the same diet. Dietary specialists are often the focus of studies of parental effects due to diet because a narrow diet breadth suggests that the offspring environment may be predictable. Dietary generalists, in contrast, are less often studied regarding parental effects and this may be because their wide diet breadth makes the future environment less predictable.

We investigated whether parental …

Metaipm: Placing Integral Projection Models Into A Metapopulation Framework, Richard A. Erickson, James P. Pierce, Greg J. Sandland, Hannah M. Thompson, Alison A. Coulter, David C. Glover

Natural Resource Management Faculty Publications

1. Metapopulation models include spatial population dynamics such as dispersion and migration between subpopulations. Integral projection models (IPMs) can include demographic rates as a function of size. Traditionally, metapopulation models do not included detailed populaiton models such as IPMs. In some situations, both local population dynamics (e.g. size-based survival) and spatial dynamics are important.
2. We present a Python package, MetaIPM, which places IPMs into a metapopulation framework, and allow users to readily construct and apply these models that combine local population dynamics within a metapopulation framework. 3. MetaIPM includes an IPM for each subpopulation that is connected to other …

Trophic Dynamics Of The Lake Superior Fish Community, Ariel Edwards

All NMU Master's Theses

The Lake Superior food web has undergone many changes in recent decades, including the rehabilitation of the native apex predator lake charr (Salvelinus namaycush) and the introduction of several nonnative species. The trophic linkages and ecological requirements of the entire fish community, including predators and prey fishes, has not been assessed on a whole-lake scale in over a decade. Here, I investigated the trophic dynamics across multiple regions of the lake, and estimated the consumptive effect of lean lake charr in one region of Lake Superior. From April to October of 2021, a total of five predator, four …

Plestiodon Egregius Insularis (Cedar Key Mole Skink). Reproduction., Jake Scott, Kevin M. Enge, Louis A. Somma, Richard D. Bartlett

Papers in Herpetology

PLESTIODON EGREGIUS INSULARlS (Cedar Key Mole Skink). REPRODUCTION. Plestiodon egregius insularis is the largest of five described subspecies (Mount 1965. Bull. Florida St. Mus. BioI. Sci. 9:183-213) and is known from only nine small islands off the coast of Levy County, Florida, USA. The only documented clutch size for P. e. insularis contained five eggs (Mount 1963. Am. MidI. Nat. 70:356-385). For wild P. egregius, Mount (1963, op. cit.) reported 2-9 (mean = 4.8) eggs for 13 clutches, and Hamilton and Pollack (1958. Herpetologica 14:25-28) found two nests of P. e. similis in Georgia containing five eggs each. In captivity, …

Hydric Physiology Of Lizards, Savannah Weaver

Master's Theses

Chapter 1: Animals can respond to extreme climate by behaviorally avoiding it, or by physiologically coping with it. We understand behavioral thermoregulation and physiological thermal tolerances, but water balance has largely been neglected. Climate change includes both global warming and changes in precipitation regimes, so improving our understanding of organismal water balance is increasingly urgent. We assessed the hydric physiology of endangered Blunt-nosed Leopard Lizards (Gambelia sila) by measuring cutaneous evaporative water loss (CEWL), plasma osmolality, body mass, and body condition throughout their active season. On average, G. sila had low CEWL that is likely desert-adaptive, and high …

Assessing The Resilience Of Mycorrhizal Networks Following Central Tree Removal, Deon Lillo

Master's Theses

Mycorrhizal networks (MNs), or the networks of fungal mycelia that connect plants to each other, are vital in contributing to the well-being of ecosystems. They not only assist in the transport of nutrients across an ecosystem, but also help protect an ecosystem from disease and adverse conditions. However, more research into these networks is needed and modelling these networks as graphs can help us achieve this. By applying centrality analysis and performing k-core partitioning on these networks, we are able to identify the trees that are most important and central to a MN and observe the effects of removing these …

Statistical And Biological Analyses Of Acoustic Signals In Estrildid Finches, Moises Rivera

Dissertations, Theses, and Capstone Projects

Acoustic communication is a process that involves auditory perception and signal processing. Discrimination and recognition further require cognitive processes and supporting mechanisms in order to successfully identify and appropriately respond to signal senders. Although acoustic communication is common across birds, classical research has largely disregarded the perceptual abilities of perinatal altricial taxa. Chapter 1 reviews the literature of perinatal acoustic stimulation in birds, highlighting the disproportionate focus on precocial birds (e.g., chickens, ducks, quails). The long-held belief that altricial birds were incapable of acoustic perception in ovo was only recently overturned, as researchers began to find behavioral and physiological evidence …

Modulatory Effects Of Schreckstoff On The Startle Escape Response Of Goldfish (Carassius Auratus), Denis Shor

Dissertations, Theses, and Capstone Projects

Fish face a variety of stressors in nature, a prominent one being a predatory threat to which they respond with an adaptive behavioral response thus maximizing their chances of survival. A primary anti-predatory behavior is a startle response or C-start. This behavior is controlled by two large reticulospinal neurons, the Mauthner cells (M-cells) which integrate multimodal sensory inputs. Detecting a predator involves various sensory information such as visual and mechanosensory cues but also olfaction. Indeed, following an attack, an injured fish will release an alarm pheromone (Schreckstoff) and thus acutely alert close by conspecifics. However, whether the alarm pheromone in …

Rethinking The Status And Temporal Occurrence Of The American Woodcock In Nebraska Because Of Its Unusual Life History, Joel G. Jorgensen, Stephen J. Brenner

Nebraska Bird Review

Historical distribution and range expansion -- We reviewed existing information to evaluate conclusions by previous authors (e.g., Sharpe et al. 2001, Silcock and Jorgensen 2023) that woodcock have expanded their range west since settlement of Nebraska by Euro-Americans. We also provide additional context about the species’ distribution over time using regional resources.

Temporal occurrence and abundance -- We used data from woodcock outfitted with satellite transmitters 2021-2022 and compared it with occurrence data from two sources, eBird (eBird.org 2023) from all years through 2022 and the SFRs in the Nebraska Bird Review 1994–2019. We chose not to use SFR data …

A Foundational Population Genetics Investigation Of The Sexual Systems Of Solanum (Solanaceae) In The Australian Monsoon Tropics Suggests Dioecious Taxa May Benefit From Increased Genetic Admixture Via Obligate Outcrossing, Jason T. Cantley, Ingrid E. Jordon-Thaden, Morgan Roche, Daniel S. Hayes, Stephamie Kate, Christopher T. Martine

Faculty Journal Articles

Solanum section Leptostemonum is an ideal lineage to test the theoretical framework regarding proposed evolutionary benefits of outcrossing sexual systems in comparison to cosexuality. Theoretically, non-cosexual taxa should support more genetic diversity within populations, experience less inbreeding, and have less genetic structure due to a restricted ability to self-fertilize. However, many confounding factors present challenges for a confident inference that inherent differences in sexual systems influence observed genetic patterns among populations. This study provides a foundational baseline of the population genetics of several species of different sexual systems with the aim of generating hypotheses of any factor—including sexual system—that influences …

Two New Genera Of Enopliinae, Skelleyus And Divulgoatus (Coleoptera: Cleridae), Weston Opitz

Insecta Mundi

Two new genera, Skelleyus Opitz and Divulgoatus Opitz (Coleoptera: Cleridae: Enopliinae), show unusual antennal development. Funicular antennomeres become shorter as they approach an extensive ca­pitulum. This study involves three taxa, Skelleyus leavengoodi Opitz, new species, Divulgoatus kelleri Opitz, new species, and Divulgoatus discrepans (Gorham).

The two new genera of Cleridae presented in this work show a most unusual antennal development. The greatly extended antennal capitulum is not found in any other member of the Enopliinae. The complete illustrations of the antennae are depicted in the species descriptions.
