Fate Of Captive-Reared Bobwhite Quail Released In Central Kentucky, Adam Carter

Online Theses and Dissertations

The fate of pen-raised bobwhite quail (Colinus virginianus) released onto two farms (Site 1 and 2) and a reclaimed coal surface mine (Site 3) in south-central Kentucky during the summers of 2008 and 2009 was assessed. Of the 57 bobwhite quail radio-tagged and released in this study, the fate of 26 (45%) was unknown because the telemetry signal was lost and the birds could not be located. Within 34 days after release, mortality of the remaining 31 radio-tagged birds was 100%. Raptors, coyotes, and mesomammal predators were responsible for most (84%) of the identified quail mortality; accounting for the deaths …

Offspring Retrieval Behaviors After Brood Loss In The Convict Cichlid, Heather Witherspoon Govert

Online Theses and Dissertations

Parents provide care for their young in several different ways. One of these is searching for and retrieving any young that may become displaced from their nest. In monogamous biparental species, parents may share care of their young, including retrieval efforts. Convict cichlids (Amatitlania siquia) are an example of a monogamous biparental fish that show shared parental care of young. In the wild, these cichlids defend nests and search for missing young in response to complete or catastrophic brood loss. This retrieval behavior is important for both parents because parents, especially the males, have been observed to abandon their mate …

Hymenolepis Folkertsi N. Sp. (Eucestoda: Hymenolepididae) In The Oldfield Mouse Peromyscus Polionotus (Wagner) (Rodentia: Cricetidae: Neotominae) From The Southeastern Nearctic With Comments On Tapeworm Faunal Diversity Among Deer Mice, Arseny A. Makarikov, Todd N. Nims, Kurt E. Galbreath, Eric P. Hoberg

Harold W. Manter Laboratory of Parasitology: Faculty Publications

A previously unrecognized species of hymenolepidid cestode attributable to Hymenolepis is described based on specimens in Peromyscus polionotus, oldfield mouse, from Georgia, United States, near the southeastern coast of continental North America. Specimens of Hymenolepis folkertsi n. sp. differ from those attributed to most other species in the genus by having testes arranged in a triangle and a scolex with a prominent rostrum-like protrusion. The newly recognized species is further distinguished by the relative position and length of the cirrus sac, shape of seminal receptacle, and relative size of external seminal vesicle and seminal receptacle. Hymenolepidid cestodes have sporadically …

Trophic Interactions In A Semiaquatic Snake Community: Insights Into The Structure Of A Floodplain Food Web, Cynthia M. Carter

Masters Theses

Food webs provide a useful conceptual framework for evaluating the relationships that exist within ecological systems. Characterizing the interactions within these webs can improve our understanding of how communities are structured and what mechanisms stabilize them. Untangling these interactions can be an intractable problem in complex systems and insights gained from conventional methods are often accompanied by inherent sources of bias. This study used stable isotope analysis, an alternative to traditional methods, to investigate the roles and relative contributions of consumers at the top of a food web to community structure and stability. I compared the niche parameters of five …

Ramapough/Ford The Impact And Survival Of An Indigenous Community In The Shadow Of Ford Motor Company’S Toxic Legacy, Chuck Stead

Antioch University Dissertations & Theses

The purpose of this study was to examine the history of the Ford Motor Company’s impact upon the Ramapo Watershed of New York and New Jersey, as well as upon the Ramapough Munsi Nation, an indigenous population living there. In a 25 year span the automaker produced a record number of vehicles and dumped a massive amount of lead paint, leaving behind a toxic legacy that continues to plaque the area and its residents. The Ramapough people are not unlike many native nations living in the United States who have experienced industrial excess. This study examines the mindset that allows …

Observations Of Hippopotamus H. Amphibius In The Little Scarcies River Of Sierra Leone And Arguments For Their Conservation Based On Roles They Play In Riverine Grasslands And Nutrient Loading, Lindsey R. Perry

Dissertations, Master's Theses and Master's Reports

A small population of Hippopotamus amphibius remains in Sierra Leone and conservation efforts may be needed to support the Hippos and their indirect benefits to fisheries and grassland production. The hippo is a known ecosystem engineer, and a potentially important contributor of nutrients to the river systems they inhabit supporting the food web and local fisheries. In this study I observed hippos in the Little Scarcies River and uplands of the Outamba-Kilimi National Park to estimate their numbers and ultimately their potential input of nutrients into the river. Hippos forage at night in grasslands neighboring rivers, removing up to 3.62 …

The Non-Lethal Effects Of Climate Change On The Territoriality Of Lottia Gigantea, Tracey Gunanto, Christina Chavez, Jessica Martinez, William G. Wright

Student Scholar Symposium Abstracts and Posters

The intertidal zone has been described as ground zero for global warming. Here, the owl limpet, Lottia gigantea, adapted to the cool ocean temperatures, must withstand a few hours of baking sun during day-time low tides. This hardship is predicted to increase in frequency and severity in the future as the globe warms. Our research hypothesized that heat events compromise territorial behavior of L. gigantea. All observations and experiments were performed at Inspiration Point near Newport Beach, California. We measured the natural radiant temperature of tagged limpets during day-time low tides using a field-calibrated infrared “thermogun”. We also …

New Study Of Altitude And Butterfly Diversity Evaluation Of Butterfly Diversity In La Hesperia And Influence Of Altitude On Diversity, Savannah Artusi

Independent Study Project (ISP) Collection

Due to the increasing effects of climate change, studies focusing on bioindicator species are becoming more necessary than ever. Additionally, knowledge about global biodiversity can be very useful to conservation organizations because it helps them determine what areas need to be conserved the most .Butterflies are useful as bioindicators due to their complex life cycles, importance in the food chain, and sensitivity to environmental changes. This project focused on studying the overall biodiversity of butterflies in the La Hesperia reserve. In addition, this study aimed to determine how butterfly diversity varies at different altitudes. To do this, the reserve was …

New Observations Of The Andean Ibis (Theristicus Branickii, Threskiornithidae): Distribution, Movements, And Behavior Near Volcán Antisana, Benjamin West

Independent Study Project (ISP) Collection

The Andean Ibis (Theristicus branickii) of the highland grasslands of Ecuador, Peru, and Bolivia is listed globally as Near Threatened and Critically Endangered in Ecuador. The Ecuadorian population is estimated at 100 individuals and is restricted to the vicinities of Volcán Antisana and Volcán Cotopaxi. Knowledge of the nesting biology of the Andean Ibis in Ecuador consists of a single filming in 1989. Much of its general ecology and movements is also unknown. The purpose of this study was to find evidence of nesting ibis in Ecuador while also collecting data on behavior, population, movements and interspecific interactions. Data was …

Birds are the most species-rich class of tetrapod vertebrates and have wide relevance across many research fields. We explored bird macroevolution using full genomes from 48 avian species representing all major extant clades. The avian genome is principally characterized by its constrained size, which predominantly arose because of lineage-specific erosion of repetitive elements, large segmental deletions, and gene loss. Avian genomes furthermore show a remarkably high degree of evolutionary stasis at the levels of nucleotide sequence, gene synteny, and chromosomal structure. Despite this pattern of conservation, we detected many non-neutral evolutionary changes in protein-coding genes and noncoding regions. These analyses …

Systematics Of The Neotropical Genus Leptodactylus Fitzinger, 1826 (Anura: Leptodactylidae): Phylogeny, The Relevance Of Non-Molecular Evidence, And Species Accounts, Rafael O. De Sá, Taran Grant, Arley Camargo, W. R. Heyer, María Laura Ponssa, Edward Stanley

Biology Faculty Publications

A phylogeny of the species-rich clade of the Neotropical frog genus Leptodactylus sensu stricto is presented on the basis of a total evidence analysis of molecular (mitochondrial and nuclear markers) and non-molecular (adult and larval morphological and behavioral characters) sampled from > 80% of the 75 currently recognized species. Our results support the monophyly of Leptodactylus sensu stricto, with Hydrolaetare placed as its sister group. The reciprocal monophyly of Hydrolaetare and Leptodactylus sensu stricto does not require that we consider Hydrolaetare as either a subgenus or synonym of Leptodactylus sensu lato. We recognize Leptodactylus sensu stricto, Hydrolaetare, Adenomera, and Lithodytes …

Natural Infections Of Tetrathyridia Of Mesocestoides Species In Deer Mice, Peromyscus Maniculatus, From New Mexico, John E. Ubelaker, Nora Abdullah, Aya Mouhaffel, Rashmi Ananadampillair, Caitlyn Emigh, Scott Lyell Gardner

Papers in Parasitology

At Southern Methodist University campus about 6 miles south of Taos, New Mexico, we recovered tetrathyridia of Mesocestoides in five Peromyscus maniculatus in the summers of 2008 (3 of 129, 0.023%), 2009 (0 of 98, 0%), 2010 (1 of 112, 0.008%), 2011 (0 of 88, 0%), and 2012 (1 of 86, 0.011%). Tetrathyridia from the body cavity of one of the five infected mice were injected into the peritoneal cavity of laboratory white mice, Mus musculus. Our later examination of the laboratory mice revealed heavy infections of tetrathyridia continuing to reproduce asexually. Here we provide important new information on …

Effects Of Large Scale Growing Season Prescribed Burns On Movement, Habitat Use, Productivity, And Survival Of Female Wild Turkey On The White Rock Ecosystem Restoration Project Of The Ozark-St. Francis National Forest, Henry Tyler Pittman

Graduate Theses and Dissertations

Restoration of woodland and savanna ecosystems has become a common management strategy in the Central Hardwoods region. Over the past two decades forest managers have implemented woodland and savanna restoration at the landscape level (≥10,000 ha), especially using early growing season prescribed fire. The implementation of the restoration strategy has coincided with declines of Eastern Wild Turkey (Meleagris gallopavo silvestris) in many treated areas causing concern that early growing season prescribed fire was impacting wild turkey. We initiated our study to examine the effect of woodland and savanna restoration on the ecology and habitat of wild turkey in the Ozark …

A New Species Of Chiasmocleis (Microhylidae, Gastrophryninae) From The Atlantic Forest Of Espírito Santo State, Brazil, João Filipe Tonini, Maruicio Forlani, Rafael O. De Sá

Biology Faculty Publications

Among Neotropical microhylids, the genus Chiasmocleis is exceptionally diverse. Most species ofChiasmocleis were described in recent years based on external morphology, but recent studies using molecular data did not support the monophyly of the species groups clustered based on feet webbing. Furthermore, a phylogeographic study of C. lacrimae estimated high genetic divergence and low gene flow among populations across small geographic ranges. Increasing the molecular and geographic sampling, and incorporating morphological data, we identified new cryptic species. Herein, we used novel genetic and morphological data to describe a new species of Chiasmocleis.

Habitat Effects On Chick-A-Dee Call Complexity, Jacqueline Renee Lynch

Open Access Theses

Past studies on the communication systems of species in urban environments (such as Common Starlings (Sturnus vulgaris), nightingales (Luscinia megarhynchos Brehm), brown-headed cowbirds ( Molothrus ater), Southern brown tree frogs (Litoria ewingii )) have shown multiple ways that species change vocal signaling behavior to adjust to urban habitats (e.g. alarm calls and singing). This study further investigates the changes in signaling in relation to the chick-a-dee call of the Carolina chickadee (Poecile carolinensis). A secondary goal of this study was to compare both the amount of information and rate of calling across …

New Species Of Ctenomys Blainville 1826 (Rodentia: Ctenomyidae) From The Lowlands And Central Valleys Of Bolivia, Scott Lyell Gardner, Jorge Salazar-Bravo, Joseph A. Cook

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The genus Ctenomys Blainville 1826 is one of the most diverse of South American hystricognath rodents. Currently, nine species of tuco-tucos are reported from Bolivia, four at elevations above 2,000 m and five inhabiting the lowlands (< 1,000 m). In the present paper, morphology, karyology, and phylogenetic analyses of DNA sequences for a mitochondrial locus were used to assess the taxonomic status of specimens of Ctenomys from localities beyond the previously known ranges of these rodents in the departments of Chuquisaca, Cochabamba, Santa Cruz, and Tarija. Based on these analyses, we describe four new species in the genus Ctenomys, all apparently endemic to the country. In addition, we place Ctenomys goodfellowi Thomas 1921 in synonymy under C. boliviensis Waterhouse 1848 and confirm the presence of C. nattereri …

Coral-Fish Dynamics And Interactions: A Case Study Of Grand Cayman, Eileen Shea Davis

Lawrence University Honors Projects

To better understand the ecological interactions of coral reefs, it is important to understand the mechanisms that control the distribution and abundance of reef-building corals as well as the mechanisms that control the diversity and abundance of the fish community that inhabits these reef habitats. The purpose of this study was to identify specific coral-fish interactions among the reefs of Grand Cayman in order to gain insight into the biological effects of fish on the assemblage of hard corals. Using data collected by the Lawrence University Marine Program (LUMP), a number of exploratory statistical analyses were run in order to …

The Neotropical Genus Austrolebias: An Emerging Model Of Annual Killifishes, Nibia Berois, María J. Arezo, Rafael O. De Sá

Biology Faculty Publications

Annual fishes are found in both Africa and South America occupying ephemeral ponds that dried seasonally. Neotropical annual fishes are members of the family Rivulidae that consist of both annual and non-annual fishes. Annual species are characterized by a prolonged embryonic development and a relatively short adult life.

Males and females show striking sexual dimorphisms, complex courtship, and mating behaviors. The prolonged embryonic stage has several traits including embryos that are resistant to desiccation and undergo up to three reversible developmental arrests until hatching. These unique developmental adaptations are closely related to the annual fish life cycle and are the …

The Nebraska Natural Legacy Project recognizes the Western Massasauga (Sistrurus tergeminus) as a Tier I at-risk species. Provided are some general management recommendations regarding Western Massasaugas. Conservation practitioners will need to use professional judgment to make specific management decisions based on objectives, location, and a multitude of variables. This resource was designed to share available knowledge of this at-risk species that will aid in the decision-making process or …

Level Of Uv-B Radiation Influences The Effects Of Glyphosate-Based Herbicide On Fitness Of The Spotted Salamander, Nicholas A. Levis

Masters Theses & Specialist Projects

Numerous causes have been implicated in contributing to amphibian population declines since the 1980's, with habitat modification, ultraviolet radiation (UV-B) and environmental contaminants (such as glyphosate-based herbicide) being among the most common. This study identifies the effects of a generic glyphosate-based herbicide (GLY- 4 Plus) on mortality, immune function, body condition, and morphological plasticity of larvae of the spotted salamander (Ambystoma maculatum) under conditions that reflect open and closed canopy light regimes. Larval salamander responses to glyphosate-based herbicide varied depending on UV-B conditions. In general, it appears that an open canopy (i.e. greater UV-B exposure) may confer fitness benefits. In …

Taxonomic And Seasonal Variation Among Extant Hyracoids Based On Dental Microwear Texture Analysis, Ann Marie Walcutt

Graduate Theses and Dissertations

A number of works have been published on habitats and diets of living hyraxes but much remains to be learned about the paleoenvironment contexts of the much larger, more dominant but now extinct forms of the order. Here, I analyze the dental microwear of modern hyraxes to assess dietary and ecological relationships among the four extant species of Procaviidae: Heterohyrax brucei, Procavia capensis, Dendrohyrax arboreus, and Dendrohyrax dorsalis. The purpose of this study was to establish an extant baseline series for the interpretation of microwear texture patterns, and inference of diets, of extinct members of the …

Effects Of Petroleum Distillates On Amphibian Development, Kate Walker

Graduate Theses and Dissertations

Petroleum distillates are widely used as an energy source and the extraction and disposal of these chemicals are done with little consideration of their effects on aquatic environments. Amphibians are considered excellent ecological indicators but little research has examined effects of petroleum distillates on aquatic species. I evaluated the lethal and sublethal effects on larval amphibians with exposure to petroleum distillates associated with various venues of pollution including hydraulic fracturing. I selected three petroleum distillates (kerosene, oil, and unleaded gasoline) that are known to have negative effects on aquatic organisms and are similar to the common constituents of mixtures used …

Scott L. Gardner Publications

Abstract

Plagioscion squamosissimus (Heckel 1840), a fish endemic to the Amazon Basin and commonly known as the “silver croaker,” plays an important role in the ecology and economy of Pará State, Brazil. Knowledge of host-parasite relationships is important to understanding the role of parasites in the control of natural host populations. This work describes histopathological aspects caused by several common intestinal parasites found during a helminthological survey of fish in northern Brazil. We observed a high prevalence of helminth infection, especially by J₃ nematode juveniles of the family Anisakidae and metacestodes of the family Protocephalidae (both with 100% prevalence). …

Hymenolepis Robertrauschi N. Sp. From Grasshopper Mice Onychomys Spp. In New Mexico And Nebraska, U.S.A., Scott Lyell Gardner, Brent A. Luedders, Donald W. Duszynski

Harold W. Manter Laboratory of Parasitology: Faculty Publications

From 1989 through 1998, a total of 358 grasshopper mice were collected and examined for helminth and protistan parasites from several habitat types on the Sevilleta Long Term Ecological Research (LTER) site in New Mexico, U.S.A. Of these, 205 individuals were identified as Onychomys leucogaster (Wied-Neuwied 1841) and 153 individuals were classified as O. arenicola Mearns 1896. Many individuals of Onychomys were infected with a new species of Hymenolepididae (Hymenolepis robertrauschi), which is herein described, illustrated, and compared with all species of Nearctic Hymenolepis s. str. Hymenolepis robertrauschi was found in 26% of the individuals of O. arenicola …

Evolutionary Relationships Of The Critically Endangered Frog Ericabatrachus Baleensis Largen, 1991 With Notes On Incorporating Previously Unsampled Taxa Into Large-Scale Phylogenetic Analyses, Karen Siu-Ting, David J. Gower, Davide Pisani, Roman Kassahun, Fikirte Gebresenbet, Michele Menegon, Abebe A. Mengistu, Samy A. Saber, Rafael O. De Sá, Mark Wilkinson, Simon P. Loader

Biology Faculty Publications

Background: The phylogenetic relationships of many taxa remain poorly known because of a lack of appropriate data and/or analyses. Despite substantial recent advances, amphibian phylogeny remains poorly resolved in many instances. The phylogenetic relationships of the Ethiopian endemic monotypic genus Ericabatrachus has been addressed thus far only with phenotypic data and remains contentious.

Results: We obtained fresh samples of the now rare and Critically Endangered Ericabatrachus baleensis and generated DNA sequences for two mitochondrial and four nuclear genes. Analyses of these new data using de novo and constrained-tree phylogenetic reconstructions strongly support a close relationship between Ericabatrachus and …

Averting Lemur Extinctions Amid Madagascar's Political Crisis, Christoph Schwitzer, Russell Mittermeier, Steig Johnson, Giuseppe Donati, Mitchell Irwin, Heather Peacock, Jonah Ratsimbazafy, Josia Razafindramanana, Edward E. Louis, Lounes Chikhi, Ian C. Colquhoun, Jennifer Tinsman, Ranier Dolch, Marni Lafleur, Stephen Nash, Erik Patel, Blanchard Randrianambinina, Tove Rasolofoharivelo, Patricia C. Wright

Anthropology Publications

The most threatened mammal group on Earth, Madagascar’s five endemic lemur families (lemurs are found nowhere else), represent more than 20% of the world’s primate species and 30% of family-level diversity. This combination of diversity and uniqueness is unmatched by any other country—remarkable considering that Madagascar is only 1.3 to 2.9% the size of the Neotropics, Africa, or Asia, the other three landmasses where nonhuman primates occur. But lemurs face extinction risks driven by human disturbance of forest habitats. We discuss these challenges and reasons for hope in light of site-specific, local actions proposed in an emergency conservation action plan.
