Microbial Impacts On Endocrine Disrupting Contaminants: Las Vegas Wash And Lake Mead, Nevada, Susanna May Blunt
Microbial Impacts On Endocrine Disrupting Contaminants: Las Vegas Wash And Lake Mead, Nevada, Susanna May Blunt
UNLV Theses, Dissertations, Professional Papers, and Capstones
International concern over endocrine disrupting chemicals (EDCs) has become heightened in recent years as more studies reveal their persistence in the environment and their detrimental effects on wildlife. However, little is known about the role of microorganisms in the fate and transport of these compounds in surface waters. Las Vegas Wash, a stream flowing into Lake Mead and fed primarily by treated wastewater effluent, provided a unique experimental system in which to study the role microorganisms play in the dispersal of these compounds in aquatic systems. Samples were collected from the Las Vegas Wash downstream of the Las Vegas Valley's …
Movement Ecology Of An Intercontinental Migratory Bird During Spring Stopover, Emily Beth Cohen
Movement Ecology Of An Intercontinental Migratory Bird During Spring Stopover, Emily Beth Cohen
Dissertations
Movement ecology is a component of nearly all aspects of animal behavior and an animal’s decision to move is likely influenced by a complex combination of exogenous and endogenous factors. Therefore, an examination of the causes and consequences of organismal movement provides a conceptual framework for understanding complex behavioral strategies. My dissertation research is focused on the movement ecology of an intercontinental migratory songbird during spring migration. I adopted experimental approaches to study the factors influencing how a songbird migrant, red-eyed vireos (Vireo olivaceus), makes decisions in unfamiliar landscapes from the initiation of spring stopover.
I simulated the …
Composition And Ecophysiological Proficiency Of Tidal Freshwater Forested Wetlands: Investigating Basin, Landscape, And Microtopographic Scales, Jamie Duberstein
Composition And Ecophysiological Proficiency Of Tidal Freshwater Forested Wetlands: Investigating Basin, Landscape, And Microtopographic Scales, Jamie Duberstein
All Dissertations
A hierarchical approach to forest community assessment was conducted by first focusing on landscape associations to edaphic factors among major tidal freshwater forested wetland basins in the Southeast. Four general tree communities exist along coastal rivers in the southeastern United States, based on the most prominent species in each: Water Tupelo, Swamp Tupelo, Dwarf Palmetto, and Cabbage Palm. Microhabitat usage and preference by trees were then examined, both across all species and within species, as related to such factors as coast, presence on rivers with dams, tree community assemblage, relative distance from the river, specific river basin, and microsite availability. …
The Invasive Cactus Moth, Cactoblastis Cactorum: Host Plant Testing, Species Interactions, And Effects On Local Opuntia Populations, Heather Jezorek
The Invasive Cactus Moth, Cactoblastis Cactorum: Host Plant Testing, Species Interactions, And Effects On Local Opuntia Populations, Heather Jezorek
USF Tampa Graduate Theses and Dissertations
The invasive cactus moth, Cactoblastis cactorum, poses a threat to opunitoid cacti species of North America. The following work contains four separate studies investigating C. cactorum host plant preference and performance, predation and parastitism of C. cactorum, effects of C. cactorum on local Opuntia populations, and associational effects of host and non-host plants on C. cactorum and native Opuntia-feeding herbivores. We found that, among southwestern and Mexican opuntioid taxa, moths preferred O. engelmannii var. linguiformis and var. engelmannii for oviposition, while Consolea rubescens and O. streptacantha were superior larval hosts. Oviposition was best predicted by number of cladodes and degree …

A Checklist Of The Scorpions (Arachnida: Scorpiones) Of Panama, With Two New Records, Rolando Teruel, Michiel A.C. Cozijn
Euscorpius
In the present note, we compile a checklist of all scorpion species recorded from Panama. A total of three families, five genera and 14 species are confirmed to occur in the country, and previous records of two other families, four genera, and nine species are discarded as misidentifications, mislabelings, or accidental introductions. Two Buthidae species are herein recorded for the first time from Panama: Tityus tayrona Lourenço, 1991 (so far known only from northern Colombia) and one apparently undescribed species of Ananteris Thorell, 1891.

Euscorpius
Centruroides edwardsii (Gervais, 1843) comb. nov. is restored as a valid species, and a male neotype from Riohacha, La Guajira Department, Colombia is herein designated; this species ranges from Mexico through Colombia, but there are no reliable records from Guatemala, Belize, and Panama; introduced populations also occur in Cuba (West Indies) and Senegal (Africa). We regard the following species as its junior synonyms: Scorpio (Atreus) degeerii Gervais, 1844, Centrurus gambiensis Karsch, 1879, Centruroides margaritatus septentrionalis Hoffmann, 1932, and Rhopalurus danieli Prado et Rios-Patiño, 1940. We also consider Centruroides margaritatus morenoi Mello-Leitão, 1945 as a junior synonym of …
No Accession-Specific Effect Of Rhizosphere Soil Communities On The Growth And Competition Of Arabidopsis Thaliana Accessions, Anna G. Aguilera, Adán Colón-Carmona, Rick Kesseli, Jeffrey S. Dukes
No Accession-Specific Effect Of Rhizosphere Soil Communities On The Growth And Competition Of Arabidopsis Thaliana Accessions, Anna G. Aguilera, Adán Colón-Carmona, Rick Kesseli, Jeffrey S. Dukes
Biology Faculty Publication Series
Soil communities associated with specific plant species affect individual plants' growth and competitive ability. Limited evidence suggests that unique soil communities can also differentially influence growth and competition at the ecotype level. Previous work with Arabidopsis thaliana has shown that accessions produce distinct and reproducible rhizosphere bacterial communities, with significant differences in both species composition and relative abundance. We tested the hypothesis that soil communities uniquely affect the growth and reproduction of the plant accessions with which they are associated. Specifically, we examined the growth of four accessions when exposed to their own soil communities and the communities generated by …

Learned Recognition And Avoidance Of Invasive Mosquitofish By The Shrimp, Paratya Australiensis, Joshua D. Bool, Kristen Whitcomb, Erin Kydd, Culum Brown
Sentience Collection
Little is known about the learning ability of crustaceans, especially with respect to their anti-predator responses to invasive species. In many vertebrates, anti-predator behaviour is influenced by experience during ontogeny. Here, predator-naïve glass shrimp (Paratya australiensisis) were exposed to a predatory, invasive fish species, Gambusia holbrooki, to determine whether shrimp could learn to: (1) avoid the scent of Gambusia via classical conditioning; and (2) restrict their activity patterns to the night to reduce predatory encounters. Conditioned shrimp were placed in containers in aquaria containing Gambusia for 3 days during which time they could be harassed but not consumed by Gambusia. …
Rocky Mountain Birds: Birds And Birding In The Central And Northern Rockies, Paul A. Johnsgard
Rocky Mountain Birds: Birds And Birding In The Central And Northern Rockies, Paul A. Johnsgard
Zea E-Books Collection
“The Rocky Mountain region has fascinated me ever since I traveled to Glacier and Yellowstone National Parks as a teenager, and saw for the first time such wonderful birds as ospreys, American dippers, and Lewis’s woodpeckers.”
This book is in part based on the author’s earlier Birds of the Rocky Mountains (1986, revised 2009), but over a third of the original text has been eliminated. The rest has been updated, expanded and modified to be less technical and more useful to birders in the field. Bird enthusiasts will find viewing locations and updated contact information for hundreds of sites in …

Thirteen species of scorpions belonging to two families are reported from the Kerman Province of Iran. Of these, the species Compsobuthus kaftani Kovařík, 2003, Mesobuthus macmahoni (Pocock, 1900), Orthochirus farzanpayi (Vachon et Farzanpay, 1987), Polisius persicus Fet, Capes et Sissom, 2001, Sassanidotus gracilis (Birula, 1900), and Hemiscorpius lepturus Peters, 1861 are recorded from the province for the first time. Kerman Province contains type localities of six species of scorpions, of which Kraepelinia palpator (Birula, 1903) and Orthochirus gruberi Kovařík et Fet, 2006 are valid. Prionurus crassicauda orientalis Birula, 1900 is a synonym of Androctonus crassicauda (Olivier, 1807), Buthus eupeus kirmanensis …
Habitat Use And Abundance Patterns Of Sandhill Cranes In The Central Platte River Valley, Nebraska, 2003–2010, Todd Joseph Buckley
Habitat Use And Abundance Patterns Of Sandhill Cranes In The Central Platte River Valley, Nebraska, 2003–2010, Todd Joseph Buckley
School of Natural Resources: Dissertations, Theses, and Student Research
The Central Platte River Valley (CPRV) in Nebraska is an important spring stopover area for the midcontinent population of sandhill cranes. Alterations to crop rotation and loss habitat in the CPRV pose a risk to the population. Personnel drove designated routes in the CPRV from 2003–2010 to record the presence of cranes in agricultural fields and estimate abundance. I developed and evaluated models to predict habitat use and flock sizes. Alfalfa was predicted to receive the highest use followed by corn, soybeans, winter wheat, grassland, and shrubland. Use of all habitats and flock size increased as field area increased. Flock …
Gravesoil Microbial Community Structure During Carcass Decomposition, Amy E. Maile
Gravesoil Microbial Community Structure During Carcass Decomposition, Amy E. Maile
Department of Entomology: Dissertations, Theses, and Student Research
Dead bodies placed on soil represent unique challenges for investigators. Although processes in soils can be used to estimate postmortem interval, we know very little about how carcasses and insects affect gravesoil microbial communities.
To address this, the current project was composed of two experiments. Experiment one was conducted to investigate the effect of surface type on carcass decomposition and evaluate soil ecology methods. Experiment two was conducted to investigate the presence of an insect population (Lucilia sericata Meigen) on gravesoil microbial communities. Both experiments were conducted in a laboratory setting using freshly killed mouse carcasses. Mouse carcasses were …
The Evolution Of Lateralized Foot Use In Parrots: A Phylogenetic Approach, Culum Brown, Maria Magat
The Evolution Of Lateralized Foot Use In Parrots: A Phylogenetic Approach, Culum Brown, Maria Magat
Sentience Collection
Cerebral lateralization refers to the division of cognitive function in either brain hemisphere and may be overtly expressed as behavioral asymmetries, such as handedness. The evolutionary history of laterality is of considerable interest due to its close link with the development of human language. Although considerable research effort has aimed at the proximate explanations of cerebral lateralization, considerably less attention has been paid to ultimate explanations. The extent to which laterality is constrained by phylogeny or shaped by ecological forces through natural selection has received little attention. Here, the foot preference of 23 species of Australian parrots was examined to …
Seed Production With Insect Herbivory And Fungal Occurrence For The Rare Penstemon Haydenii, Kay L Kottas, James Stubbendieck, Erin E. Blankenship, Jay B. Fitzgerald
Seed Production With Insect Herbivory And Fungal Occurrence For The Rare Penstemon Haydenii, Kay L Kottas, James Stubbendieck, Erin E. Blankenship, Jay B. Fitzgerald
Transactions of the Nebraska Academy of Sciences and Affiliated Societies
We quantified seed production and viability, floral herbivory and fungal infection on blowout penstemon (Penstemon haydenii S. Watson), an endangered species of the Nebraska Sandhills, USA, in order to determine the potential for perpetuation of this, and possibly other short-lived, rare perennials of fragmented habitats. Over three years, the number of seeds per infructescence averaged 518 (SE 29.01). Plants produced an average of 1398 seeds. Seed viability of 38% reduced reproductive potential to 531 viable seeds per plant. Plants in multiple blowout sites in two counties were assigned to one of four treatments: insecticide, fungicide, both, or neither (control). …

Molecular Systematics Of The Middle American Genus Hypopachus (Anura: Microhylidae), Eli Greenbaum, Eric N. Smith, Rafael O. De Sá
Biology Faculty Publications
We present the first phylogenetic study on the widespread Middle American microhylid frog genus Hypopachus. Partial sequences of mitochondrial (12S and 16S ribosomal RNA) and nuclear (rhodopsin) genes (1275 bp total) were analyzed from 43 samples of Hypopachus, three currently recognized species of Gastrophryne, and seven arthroleptid, brevicipitid and microhylid outgroup taxa. Maximum parsimony (PAUP), maximum likelihood (RAxML) and Bayesian inference (MrBayes) optimality criteria were used for phylogenetic analyses, and BEAST was used to estimate divergence dates of major clades. Population-level analyses were conducted with the programs NETWORK and Arlequin. Results confirm the placement of Hypopachus …

Hubbard Center for Genome Studies (HCGS)
Nematodes and fungi are both ubiquitous in marine environments, yet few studies have investigated relationships between these two groups. Microbial species share many well-documented interactions with both free-living and parasitic nematode species, and limited data from previous studies have suggested ecological associations between fungi and nematodes in benthic marine habitats. This study aimed to further document the taxonomy and distribution of fungal taxa often co-amplified from nematode specimens. A total of 15 fungal 18S rRNA phylotypes were isolated from nematode specimens representing both deep-sea and shallow water habitats; all fungal isolates displayed high pairwise sequence identities with published data in …

Electrosensory Ampullary Organs Are Derived From Lateral Line Placodes In Bony Fishes, Melissa S. Modrell, William E. Benis, R. Glenn Northcutt, Marcus C. Davis, Clare V.H. Baker
Faculty Articles
Electroreception is an ancient subdivision of the lateral line sensory system, found in all major vertebrate groups (though lost in frogs, amniotes and most ray-finned fishes). Electroreception is mediated by 'hair cells' in ampullary organs, distributed in fields flanking lines of mechanosensory hair cell-containing neuromasts that detect local water movement. Neuromasts, and afferent neurons for both neuromasts and ampullary organs, develop from lateral line placodes. Although ampullary organs in the axolotl (a representative of the lobe-finned clade of bony fishes) are lateral line placode-derived, non-placodal origins have been proposed for electroreceptors in other taxa. Here we show morphological and molecular …

Urban environments pose special challenges to flora, including altered disturbance regimes, habitat fragmentation, and increased opportunity for invasion by non-native species. In addition, urban natural area represents most people’s contact with nature, given the majority of the world’s population currently live in cities. We used coefficients of conservatism (C-values), a system that ranks species based on perceived fidelity to remnant native plant communities that retain ecological integrity, to quantify habitat quality of 14 sites covering 850 ha within the city of Indianapolis, Indiana, in the Midwestern United States. All sites contained significant natural area and were inventoried via intensive complete …

1. Cougar (Puma concolor) populations, like other large carnivores, have increased during recent decades and may be recolonizing their former ranges in Midwestern North America. The dispersal routes taken by these animals from established populations are unknown and insight into these movements would facilitate their conservation and management.
2. We inferred the origin and migration route of four dispersing cougars using stable hydrogen (δD) and carbon (δ13C) isotope values along one of their claws. We compared isotopic variations within claws to regional and large-scale isoscapes of δD and δ13C values in prey species. Using …

Canada Goose Crop Damage Abatement In South Dakota, Troy M. Radtke, Charles D. Dieter
Natural Resource Management Faculty Publications
Canada geese (Branta canadensis) can cause considerable damage to crops during summer when geese are flightless. We evaluated the effectiveness of a program designed to alleviate crop damage on soybeans by Canada geese in South Dakota, USA. The applications of electric fences, feeding stations, and propane cannons reduced the area of crop damage by 90% in 2006 and 80% in 2007, but the timing was important. Fields where abatement practices were applied early in the growing season had less damage than fields where they were applied later. Abatement practices that were properly applied as soon as damage started …
