Avian And Salamander Response To Young Forest Management In West Virginia, Eric L. Margenau
Graduate Theses, Dissertations, and Problem Reports (ETD)
This dissertation focuses on the effects of various young forest habitat management techniques on the avian and salamander community in West Virginia. Wildlife species associated with the nascent stage of forest succession are experiencing precipitous population declines throughout much of the eastern United States due to decreases in the amount of young forest area which have been brought on by changes in disturbance regimes over the past century. As a result, the need to find novel approaches for creating young forest habitats to sustain young forest wildlife populations is necessary. However, young forest habitat creation often negatively affects species that …

Selection Of Forage And Avoidance Of Predation Risk By Partially Migratory Mule Deer, Collin Jeffrey Peterson
Graduate Student Theses, Dissertations, & Professional Papers
Migration by ungulates has traditionally been thought of as a strategy that increases access to forage quality or reduces exposure to risk of predation, but the benefits of migration may be waning globally. In partially migratory populations, the persistence of both migrant and resident strategies is an intriguing ecological phenomenon, because migrants and residents often face contrasting fitness consequences. Partial migration is common in mule deer (Odocoileus hemionus), a species that has experienced widespread declines across the western United States during recent decades. Mule deer seldom switch between migratory strategies throughout their lifetime, which may make them less resilient to …

After Decades Of Suburban Deer Research And Management In The Eastern United States: Where Do We Go From Here?, Paul D. Curtis
Human–Wildlife Interactions
State wildlife agencies have regulatory authority and oversight over deer (Cervidae) management in the United States. However, increased urban sprawl and overabundant deer populations have created increased human–deer conflicts. Because of the growing controversy surrounding the use of traditional management practices such as regulated hunting in suburban areas in the eastern United States, managers are now using specialized tools and management approaches to reduce deer conflicts in urban areas. However, this has created new challenges as they try to meet the desires of diverse stakeholder groups. Although deer management programs in urban areas differ somewhat in every state, effective management …

Monograph Reduced Box Price: Managing Human–Deer Conflicts
Human–Wildlife Interactions
Order form for HWI monograph, Methods for Managing Human–Deer Conflicts in Urban, Suburban, and Exurban Areas. This monograph identifies challenges and benefits associated with many human–deer conflict mitigation actions as well as methods to monitor the response of deer populations to management actions. Deer exploit urban, suburban, and exurban areas where human populations provide anthropogenic attractants, either intentionally or inadvertently, which often leads to human–deer conflicts. Mitigating actions have varying degrees of efficacy and may not be effective or accepted in every situation. Wildlife and municipal managers must work together to seek methods to reduce attractants, mitigate conflicts, and perpetuate …

Analysis Of Changes In Genes That Lead To Antibiotic Resistance In Klebsiella Pneumoniae 43816, Jasmine R. Anderson
UNF Graduate Theses and Dissertations
Klebsiella pneumoniae is a Gram-negative bacterium responsible for nosocomial infections such as blood stream infections, meningitis, and septicemia. Clinical isolates confirm K. pneumoniae is increasingly antibiotic resistant (AR) making treatment more difficult. While bacterial exposure to antimicrobial substances is a known cause of the AR phenotype, there still exists gaps in knowledge about the genetic changes responsible for this fitness change. The laboratory Klebsiella pneumoniae 43816 (ATCC 43816) was exposed to sublethal concentrations of Cephalothin for a 14-day period. At the end of the experimental treatment, the adapted population acquired clinical antibiotic resistance along with phenotypic and morphological changes. The …

Predation Effects On Mid-Marsh Ribbed Mussel Mortality, Cluster Size, And Facilitation Of Cordgrass Growth, Colten Winter, Keith Walters
Honors Theses
Reciprocal facilitation between Geukensia demissa, ribbed mussels, and Sporobolus alterniflorus, cordgrass, has a positive effect on salt marsh ecosystems. Mussel clusters enhance cordgrass growth and drought resistance and cordgrass provides attachment and shade for mussel aggregations. Along with benefits for both mussels and cordgrass, the mutualism facilitates increased biodiversity and shoreline stabilization and enhances marsh ecosystem functions. Aspects of mussel patch configuration including cluster size, perimeter and connectivity modulate the reciprocal facilitation effects of cordgrass and mussels on marsh ecosystems. In a northern South Carolina marsh system, mussel patch configuration positively influenced cordgrass biomass. Predation affected mussel patch …

Vines In The Neotropics: Phylogenomics, Biogeography And Systematics In Passion Flowers (Passiflora Subgenus Decaloba Section Decaloba), Serena Acha
Dissertations
With 600 species, Passiflora is a large, morphologically complex and broadly distributed genus in Passifloraceae that represents a major challenge to scientists interested in understanding the evolutionary history of tropical vines. Passiflora has been divided into subgenera, super sections and sections. One of the most enigmatic and species-rich (~120 spp.) groups in Passiflora is section Decaloba, which occurs in the Neotropics and is particularly diverse in Andean montane forests. In this study, we used phylogenomic and population genomic approaches to investigate the evolutionary history, biologeography, species boundaries, and taxonomy of Passiflora section Decaloba. We sampled herbarium specimens, extracted …

Dynamics Of Avian Elevational Ranges Reveal Hidden Evolutionary Forces, Chauncey R. Gadek
Biology ETDs
The distribution of life across the Andes mountains reflects historical elevational-range contraction and expansion. Whereas contraction implies specialization, expansion requires overcoming hidden barriers. Three eco-evolutionary phenomena may drive patterns in rates of elevational range evolution: (1) The Dobzhansky-MacArthur Phenomenon (DMP) predicts lower rates of upward expansion with harsher physical conditions, while downward expansion increases with lower diversity; (2) the evolutionary tendency toward specialization predicts contraction increases when ranges are broad; and (3) natural selection for respiratory performance could suppress expansion across mid-elevations due to gene-environment mismatch. We modeled elevational range shifts of Neotropical landbirds. Contrary to the DMP, upward expansion …

Mycobiome Analysis Of Trees Selected By Black-Capped Chickadees (Poecile Atricapillus) As Nest Sites, Connor Gable
All NMU Master's Theses
Decay fungi may aid primary cavity excavators, such as woodpeckers, in nest excavation by softening wood, and in turn the excavators disperse fungi. Recent molecular techniques have allowed researchers to examine communities of fungi present in environmental samples more comprehensively than ever before. However, this association has not been examined for primary excavating songbirds (Passeriformes). In this study, I examine the communities of fungi in trees selected by black-capped chickadees (Poecile atricapillus) and compare them to communities in non-selected control trees to determine whether chickadee nest trees are associated with specific fungal taxa and communities. Overall, I identified …

Rasp 4: Ancestral State Reconstruction Tool For Multiple Genes And Characters, Yan Yu, Christopher Blair, Xingjin He
Publications and Research
With the continual progress of sequencing techniques, genome-scale data are increasingly used in phylogenetic studies. With more data from throughout the genome, the relationship between genes and different kinds of characters is receiving more attention. Here, we present version 4 of RASP, a software to reconstruct ancestral states through phylogenetic trees. RASP can apply generalized statistical ancestral reconstruction methods to phylogenies, explore the phylogenetic signal of characters to particular trees, calculate distances between trees, and cluster trees into groups. RASP 4 has an improved graphic user interface and is freely available from http://mnh.scu.edu.cn/soft/blog/RASP (program) and https://github.com/sculab/RASP (source code).

Predictors Of Bat Species Richness Within The Islands Of The Caribbean Basin, Justin D. Hoffman, Gabrielle Kadlubar, Scott C. Pedersen, Roxanne J. Larsen, Peter A. Larsen, Carleton J. Phillips, Gary G. Kwiecinski, Hugh H. Genoways
University of Nebraska State Museum: Mammalogy Papers
Several mechanisms have been shown to influence species richness among island ecosystems, yet most studies limit their focus to a few predictor variables. The objective of this study is to investigate variation in Chiropteran richness across islands in the Caribbean Basin with an extensive set of predictor variables. Using recent faunal surveys, the most contemporary list of bat species per island was complied. Data were collected on 17 predictor variables, which summarized five general island characteristics including island area, isolation, habitat diversity, human impact, and climate. An information-theoretic approach was used by fitting alternative candidate models to determine which variable(s) …
