Community Structure And Production Of The Macrobenthos On Four Artificial Reefs In The Mississippi Sound In Relation To Substrate And Profile Type, Patrick Daniel Gillam Aug 2016

Community Structure And Production Of The Macrobenthos On Four Artificial Reefs In The Mississippi Sound In Relation To Substrate And Profile Type, Patrick Daniel Gillam

Master's Theses

In recent years, the Mississippi Department of Marine Resources (DMR) has made a concerted effort to enhance its coastal fishery resources by creating artificial reefs. Through this effort, 73 nearshore reefs have been created across the MS coast. Different substrate types used to construct MS artificial reefs include oyster shell and cement rubble. Two types of reef architecture used include high profile breakwater and low profile submerged structures. This study compared the benthic biota associated with oyster shell and cement rubble substrates among four artificial reefs representing high and low profile structures in summer 2011. Colonized benthic biota were quantified …

Decolonizing The Ya North: Environmental Injustice In Sherri L. Smith’S Orleans, Micah-Jade M. Coleman Aug 2016

Decolonizing The Ya North: Environmental Injustice In Sherri L. Smith’S Orleans, Micah-Jade M. Coleman

Master's Theses

Young Adult (YA) dystopias, in recent years, have imagined a future world fueled by the overuse and misuse of technology, the advancement of science for human gain, as well as societies ruled by governments that govern based on their own self-interests and economic gain. Such novels have opened the door for discussion about how the present-day actions of societies can impact the future of the environment; yet many only focus their attention on societies in the North— regions considered “developed” by the western world. In her YA novel, Orleans (2014), Sherri L. Smith focuses attention on the aftermath of Hurricane …

Development Of An In Silico Kir Genotyping Algorithm And Its Application To Population And Cancer Immunogenetic Analyses, Howard Rosoff Aug 2016

Development Of An In Silico Kir Genotyping Algorithm And Its Application To Population And Cancer Immunogenetic Analyses, Howard Rosoff

Dissertations and Theses (Open Access)

Gene content determination and variant calling in the complex KIR genomic region are useful for immune system function analysis, pathogenesis and disease risk factor elucidation, immunotherapy development, evolutionary investigations, and human migration modeling. Sequence-specific oligonucleotide and sequence-specific primer PCR methods are the de facto standards for KIR presence/absence identification, but the current platforms are unsuitable for SNP calling, impractical for KIR typing large cohorts of DNA samples, and inapplicable for typing repositories in which sequence data, but not cells or cell analytes, are available. Alternative typing methods, such as in silico sequence-based typing, can address the problems associated with amplicon-based …

The Effectiveness Of Periodically-Harvested Closures In Meeting Ecological And Socioeconomic Objectives, Paul G. Carvalho Aug 2016

The Effectiveness Of Periodically-Harvested Closures In Meeting Ecological And Socioeconomic Objectives, Paul G. Carvalho

Master's Theses

Periodically-harvested fisheries closures (PHCs) are a widespread form of community-based marine spatial management used throughout the Indo-Pacific that also is currently being intensively advocated by conservation organizations for supporting productive fisheries and healthy marine ecosystems. However, local implementation of PHCs has historically been designed to support occasional and efficient exploitation of fish stocks, and not necessarily sustainable fisheries yields and stock conservation. The efficacy of PHCs for achieving their historical cultural objectives of periodicity and efficiency of harvest, simultaneously with achieving contemporary fisheries objectives of fisheries productivity and conservation is undetermined. As a result, the utility of PHCs for supporting …

Effects Of Experimental Noise Exposure On Songbird Nesting Behaviors And Nest Success, Tracy I. Mulholland Aug 2016

Effects Of Experimental Noise Exposure On Songbird Nesting Behaviors And Nest Success, Tracy I. Mulholland

Master's Theses

Anthropogenic noise is an increasingly prevalent global disturbance. Animals that rely on the acoustical environment, such as songbirds, are especially vulnerable to these sounds. Traffic noise, in particular, overlaps with the frequency range of songbirds, creating masking effects. We investigated the effects of chronic traffic noise on provisioning behaviors and breeding success of nesting western bluebirds (Sialia mexicana) and ash-throated flycatchers (Myiarchus cinerascens). Because anthropogenic noise exposure has the potential to interrupt parent-offspring communication and alter vigilance behaviors, we predicted that traffic noise would lead to changes in provisioning behaviors, such as fewer visits to the …

The Preservation And Protection Of Native Biodiversity In The Guadalupe Nipomo Dunes Complex, Lindsey M. Whitaker, Matthew Ritter, Scott J. Steinmaus, Jonathan Hall Aug 2016

The Preservation And Protection Of Native Biodiversity In The Guadalupe Nipomo Dunes Complex, Lindsey M. Whitaker, Matthew Ritter, Scott J. Steinmaus, Jonathan Hall

Master's Theses

The Guadalupe Nipomo Dunes Complex (GNDC) is located within the California Floristic Province, a biodiversity hotspot characterized by high rates of endemism and exceptional loss of habitat. In 1980, the US Fish and Wildlife Service described the GNDC as, “the most unique and fragile ecosystem in the State of California,” and ranked it first on a list of 49 habitat areas needing state protection. It is the largest coastal dune area in California and it is one of the last remaining, relatively intact ecosystems of its type and size in the western United States. The growing recognition of species decline …

Exploring The Relationship Between Behaviour And Neurochemistry In The Polyphenic Spider, Anelosimus Studiosus (Araneae: Theridiidae), Jennifer B. Price Aug 2016

Exploring The Relationship Between Behaviour And Neurochemistry In The Polyphenic Spider, Anelosimus Studiosus (Araneae: Theridiidae), Jennifer B. Price

Electronic Theses and Dissertations

The importance of social behaviour is evident in human society, but there are both costs and benefits associated with cooperation and sociality throughout the animal kingdom. At what point do the benefits outweigh the costs, and when do selective pressures favour sociality and colonization over solitude and independence? To investigate these questions, we have focused on an anomalous species of spider, Anelosimus studiosus, also known now as the northern social spider. Throughout its broad range, A. studiosus is solitary and aggressive, but recently, colonies of cooperative and social individuals have been observed at northern latitudes. This leads to two …

Phylogenomics Of Rickettsia Parkeri Isolates From The Eastern United States, Stephanie L. Grizzard Aug 2016

Phylogenomics Of Rickettsia Parkeri Isolates From The Eastern United States, Stephanie L. Grizzard

Biomedical Sciences Theses & Dissertations

Rickettsia parkeri is a tick-borne pathogen that causes R. parkeri rickettsiosis, a spotted fever rickettsiosis. The main vector of R. parkeri in the eastern United States is Amblyomma maculatum, also known as the Gulf Coast tick (GCT). The GCT has been undergoing a northward expansion from the original historic range. Whether R. parkeri expands with the GCT or has a local reservoir is unknown. Currently, there are R. parkeri-positive GCTs as far north as Delaware and New York. Expansion patterns for the GCT and R. parkeri remain unresolved but some studies point to long-distance host drop-offs as a …

Analysis Of The Intricacies Of Substrate Recognition Of High Mobility Group Proteins And Aminoacyl-Trna Synthetases Using Non-Cognate Substrates, Douglas Van Iverson Ii Aug 2016

Analysis Of The Intricacies Of Substrate Recognition Of High Mobility Group Proteins And Aminoacyl-Trna Synthetases Using Non-Cognate Substrates, Douglas Van Iverson Ii

Dissertations

The studies presented in section 1 (Chapters I-IV) focus on the design and development of nucleic acid four-way junctions (4WJs) to target a member of the high mobility group (HMG) proteins, the proinflammatory cytokine high mobility group box 1 protein (HMGB1). In the present study, hybrid PNA-DNA 4WJs based on a model DNA 4WJ were constructed to improve the thermal stability of 4WJs while maintaining strong binding affinity toward HMGB1. An electrophoretic mobility shift assay (EMSA) was used to examine the binding affinity of an isolated DNA binding domain of HMGB1, the HMGB1 b-box (HMGB1b), toward a set of PNA-DNA …

Variation Of Small Mammal Populations Across Different Habitat Types In The Serengeti Ecosystem, Flora J Magige Jul 2016

Variation Of Small Mammal Populations Across Different Habitat Types In The Serengeti Ecosystem, Flora J Magige

Tanzania Journal of Science

This study investigated the abundance and diversity of small mammals in cultivated land (unprotected area) and wooded grassland in the Serengeti National Park (protected area) in the Serengeti ecosystem. Small mammal populations were sampled through capture-mark-recapture trapping techniques in March-April 2010. A total of 896 trap nights covering wet season, 9 species of rodents and 1 species of soricomorphs (shrew family) were captured. Overall, Multimammate rat Mastomys natalensis (Smith) was by far the most abundant rodent in cultivated land (28%) while inside the park, shrew Crocidura sp., was high in numbers (8%). A significantly higher abundance (trap success) of small …

Functional Diversity Of Small And Large Trees Along Secondary Succession In A Tropical Dry Forest, Lucía Sanaphre-Villanueva, Juan Manuel Dupuy, José Luis Andrade, Casandra Reyes-García, Horacio Paz, Paula C. Jackson Jul 2016

Functional Diversity Of Small And Large Trees Along Secondary Succession In A Tropical Dry Forest, Lucía Sanaphre-Villanueva, Juan Manuel Dupuy, José Luis Andrade, Casandra Reyes-García, Horacio Paz, Paula C. Jackson

Faculty Articles

Functional Diversity is considered an important driver of community assembly in environmental and successional gradients. To understand tree assembly processes in a semideciduous tropical forest, we analyzed the variation of Functional Richness (FRic), Functional Divergence (FDiv), and Functional Evenness (FEve) of small vs. large trees in relation to fallow age after slash-and-burn agriculture and topographical position (flat sites vs. hills). FRic of small trees was lower than null model predicted values across the successional gradient, and decreased unexpectedly in older successional ages. FRic of large trees was higher than null model predictions early in succession and lower in late-successional stands …

Thirty Years Of Compositional Change In An Old-Growth Temperate Forest: The Role Of Topographic Gradients In Oak-Maple Dynamics, Julia I. Chapman, Ryan W. Mcewan Jul 2016

Thirty Years Of Compositional Change In An Old-Growth Temperate Forest: The Role Of Topographic Gradients In Oak-Maple Dynamics, Julia I. Chapman, Ryan W. Mcewan

Biology Faculty Publications

Ecological communities are structured in response to spatial and temporal variation of numerous factors, including edaphic conditions, biotic interactions, climatic patterns and disturbance regimes. Widespread anthropogenic factors such as timber harvesting can create long-lasting impacts, obscuring the relationship between community structure and environmental conditions. Minimally impacted systems such as old-growth forests can serve as a useful ecological baseline for predicting long-term compositional shifts. We utilized decadal tree species sampling data (1979–2010) divided into three strata (understory, midstory, overstory) to examine temporal changes in relative abundances and spatial distributions of dominant taxa, as well as overall shifts in community composition, in …

Caterpillars, Consciousness And The Origins Of Mind, Arthur S. Reber Jul 2016

Caterpillars, Consciousness And The Origins Of Mind, Arthur S. Reber

Animal Sentience

A novel framework for the origins of consciousness and mind, the Cellular Basis of Consciousness (CBC), is presented. The model is based on a simple, perhaps radical axiom: subjectivity is an inherent feature of particular kinds of organic form. Experiential states, including those denoted as "mind" and "consciousness," are present in the most primitive species. The model has several conceptual and empirical virtues, among them: (a) it (re)solves the problem of how minds are created by brains ─ also known as the "Hard Problem" (Chalmers 1995) ─ by revealing that the apparent difficulty results from a category error, (b) it …

Graemeloweus, A New Scorpion Genus From Northern California, Usa (Scorpiones: Vaejovidae), Michael E. Soleglad, Victor Fet, Matthew R. Graham, Richard F. Ayrey

Euscorpius

Genus Graemeloweus, gen. nov. (Scorpiones: Vaejovidae) is described from northern California, USA. The genus is composed of three species formerly placed in Pseudouroctonus: Graemeloweus iviei (Gertsch et Soleglad, 1972), comb. nov. (type species), G. glimmei (Hjelle, 1972), comb. nov., and G. maidu (Savary et Bryson, 2016), comb. nov. Major diagnostic characters of Graemeloweus include a non-bifurcated primary lamellar hook, the presence of a secondary lamellar hook, a complex mating plug with a two part base and an asymmetric crescent-shape barb, and the presence of a well-developed ventromedian (V2) carina on the pedipalp chela. Evidence is presented suggesting that …

First Record Of The Non-Native Suckermouth Armored Catfish Hypostomus Cf. Niceforoi (Fowler 1943) (Siluriformes: Loricariidae) From Central America, Wilfredo A. Matamoros, Caleb D. Mcmahan, Carlos R. Mejia, Parker H. House, Jonathan W. Armbruster, Prosanta Chakrabarty Jul 2016

First Record Of The Non-Native Suckermouth Armored Catfish Hypostomus Cf. Niceforoi (Fowler 1943) (Siluriformes: Loricariidae) From Central America, Wilfredo A. Matamoros, Caleb D. Mcmahan, Carlos R. Mejia, Parker H. House, Jonathan W. Armbruster, Prosanta Chakrabarty

Occasional Papers of the Museum of Natural Science, Louisiana State University

We document the first record of Hypostomus cf. niceforoi in Central America. Two specimens of these suckermouth armored catfishes were collected in Lake Nicaragua (Nicaragua) and identified as H. cf. niceforoi. Hypostomus niceforoi is endemic to Andean streams of Colombia, Venezuela, Ecuador, and Peru. We hypothesize that its introduction in Central America is related to the aquarium trade, as is the case of other armored catfish species introductions.

The North American Geese: Their Biology And Behavior, Paul A. Johnsgard Jul 2016

The North American Geese: Their Biology And Behavior, Paul A. Johnsgard

Zea E-Books Collection

The eight currently recognized species of North American geese are part of a familiar group of birds collectively called waterfowl, all of which are smaller than swans and generally larger than ducks. They include the most popular of our aquatic gamebirds, with several million shot each year by sport hunters. Our two most abundant waterfowl, the Canada goose and snow goose, have populations collectively totaling about 15 million individuals. Like swans, the lifelong pairbonding of geese, their familial care, and prolonged social attachment to their offspring are legendary. Their seasonal migratory flights sometimes span thousands of miles, and the sight …

Effects Of Shoreline Dynamics On Saltmarsh Vegetation, Shailesh Sharma, Joshua Goff, Ryan M. Moody, Ashley Mcdonald, Dorothy Byron, Kenneth L. Heck Jr., Sean Powers, Carl Ferraro, Just Cebrian

University Faculty and Staff Publications

We evaluated the impact of shoreline dynamics on fringing vegetation density at mid- and low-marsh elevations at a high-energy site in the northern Gulf of Mexico. Particularly, we selected eight unprotected shoreline stretches (75 m each) at a historically eroding site and measured their inter-annual lateral movement rate using the DSAS method for three consecutive years. We observed high inter-annual variability of shoreline movement within the selected stretches. Specifically, shorelines retrograded (eroded) in year 1 and year 3, whereas, in year 2, shorelines advanced seaward. Despite shoreline advancement in year 2, an overall net erosion was recorded during the survey …

"Beyond Words," Yes, But Also Beyond Numbers, Fred L. Bookstein Jul 2016

"Beyond Words," Yes, But Also Beyond Numbers, Fred L. Bookstein

Animal Sentience

Safina’s fascinating series of fifty separate feuilletons tries to bridge a painful Methodenstreit in contemporary ethology mainly by an accumulation of anecdotes. Some deal with his own dogs, but most derive from reading or conversing with observers of a wider range of social mammals including elephants, wolves, apes, and whales. In spite of the many interruptions by travesties of the academic lifestyle and its literature, there is a point to be made, concerning the centrality of evidence about cooperative behavior styles, especially aspects of child-rearing, for the understanding of “what animals think and feel.” But Safina’s argument would be a …

Maternity Colony Of Northern Long-Eared Myotis (Myotis Septentrionalis) In A Human-Made Structure In Nebraska, Rachel M. Stein, Jeremy A. White Jul 2016

Maternity Colony Of Northern Long-Eared Myotis (Myotis Septentrionalis) In A Human-Made Structure In Nebraska, Rachel M. Stein, Jeremy A. White

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

The Northern Long-eared Myotis (Myotis septentrionalis) occurs across eastern North America, and its range extends west into the Great Plains of the United States. Summer roosts of M. septentrionalis in the Great Plains are not well documented. Herein we describe a maternity colony of M. septentrionalis using small, elevated structures (i.e., cabins) in southeastern Nebraska. Cabins were in a small parcel of upland deciduous forest about 1.6 km from the Missouri River. The maternity colony was observed roosting in a space between the outer and inner walls of three different cabins from 21 June to 8 October 2014. …

Animals Are Agents, Linda A.W. Brakel Jul 2016

Animals Are Agents, Linda A.W. Brakel

Animal Sentience

Mark Rowlands’s (2016) target article invites us to consider individuals in a broad subset of the non-human animal world as genuine persons. His account features animals reacting to salient environmental stimuli as Gibsonian affordances, which is indicative of “pre-reflective self-awareness.” He holds that such pre-reflective self-awareness is both “immune to error through misidentification” (Shoemaker, 1968) and a necessary precursor to reflective consciousness and personhood. I agree. In this commentary I hope to extend Rowlands’s work with a view in which agency is an even more fundamental precursor and one can (and should) consider individuals throughout the entire animal kingdom as …

Disease Introduction Is Associated With A Phase Transition In Bighorn Sheep Demographics, Kezia R. Manlove, E. Frances Cassirer, Paul C. Cross, Raina K. Plowright, Peter J. Hudson

Wildland Resources Faculty Publications

Ecological theory suggests that pathogens are capable of regulating or limiting host population dynamics, and this relationship has been empirically established in several settings. However, although studies of childhood diseases were integral to the development of disease ecology, few studies show population limitation by a disease affecting juveniles. Here, we present empirical evidence that disease in lambs constrains population growth in bighorn sheep (Ovis canadensis) based on 45 years of population‐level and 18 years of individual‐level monitoring across 12 populations. While populations generally increased (λ = 1.11) prior to disease introduction, most of these same populations experienced an abrupt change …

Implicit Mental Processes Are An Improbable Basis For Personhood, Michael L. Woodruff Jul 2016

Implicit Mental Processes Are An Improbable Basis For Personhood, Michael L. Woodruff

Animal Sentience

Rowlands argues that animals have implicit pre-reflective awareness and that this is adequate to create the unity of conscious thought required for personhood. For him pre-reflective awareness does not include intentionality and is probably an unconscious process. I suggest that his sense of implicit leads to significant difficulties for his argument and that including intentionality in the definition of a first-person perspective provides a stronger base for viewing animals as persons.

Agriculture is an indispensable part of every person’s life, ensuring that nutritious and inexpensive food is readily available. Agriculture continues to be confronted with epidemics, having devastating effects on economies and the plant sources essential for human and animal life. Plants and their pathogens have developed evolutionary adaptations, each shaping the other’s defence and invasive strategies. Many different plants produce toxic ribosome inactivating proteins that aid in their defence mechanisms against pathogenic invaders. Viruses must adapt to the host translational machinery, several having evolved to include viral genome-linked proteins that carry numerous viral functions. Here, we review how a potyviral …

Are Animals Persons?, Mark Rowlands Jul 2016

Are Animals Persons?, Mark Rowlands

Animal Sentience

It is orthodox to suppose that very few, if any, nonhuman animals are persons. The category “person” is restricted to self-aware creatures: humans (above a certain age) and possibly some of the great apes and cetaceans. I argue that this orthodoxy should be rejected, because it rests on a mistaken conception of the kind of self-awareness relevant to personhood. Replacing this with a sense of self-awareness that is relevant requires us to accept that personhood is much more widely distributed through the animal kingdom.
