Gulf Sturgeon (Acipenser Oxyrinchus Desotoi) Pre-Restoration Occupancy Patterns On Ship Island, Mississippi Sound With An Evaluation Of Designated Critical Habitat Use By Eastern And Western Population Segments, Page Elizabeth Vick 2016 University of Southern Mississippi

Gulf Sturgeon (Acipenser Oxyrinchus Desotoi) Pre-Restoration Occupancy Patterns On Ship Island, Mississippi Sound With An Evaluation Of Designated Critical Habitat Use By Eastern And Western Population Segments, Page Elizabeth Vick

Master's Theses

Critical spawning and feeding habitat was designated for federally threatened, anadromous Gulf Sturgeon (GS) to aid in population recovery. This study examined GS occupancy, habitat use, and movement through critical habitat monitored by the Ship Island (SI) acoustic array during overwintering periods from 2011 to 2015 prior to MsCIP SI restoration. An occupancy index analyzed patterns of spatial and temporal habitat use of both western and eastern population segments (WPS and EPS, respectively) of GS on the SI array. The ends of SI along with the passes and cuts of the island, especially Dog Keys Pass (DKP), were occupied by ...


Modern Fair-Weather And Storm Sediment Transport Around Ship Island, Mississippi: Implications For Coastal Habitats And Restoration Efforts, Eve Rettew Eisemann 2016 University of Southern Mississippi

Modern Fair-Weather And Storm Sediment Transport Around Ship Island, Mississippi: Implications For Coastal Habitats And Restoration Efforts, Eve Rettew Eisemann

Master's Theses

The Mississippi – Alabama barrier island chain is experiencing accelerated sea level rise, decreased sediment supply, and frequent hurricane impacts. These three factors drive unprecedented rates of morphology change and ecosystem reduction. All islands in the chain have experienced land loss on the order of hectares per year since records began in the 1840s. In 1969, Hurricane Camille impacted as a Category 5, breaching Ship Island, and significantly reduced viable seagrass habitat. Hurricane Katrina impacted as a Category 3 in 2005, further widening Camille Cut. To better understand the sustainability of these important islands and the ecosystems they support, sediment transport ...


Examining The Combined Effects Of Dissolved Oxygen, Temperature, And Body Size On The Physiological Responses Of A Model Macrobenthic Polychaete Species, Capitella Teleta, Kelsey Burns Gillam 2016 University of Southern Mississippi

Examining The Combined Effects Of Dissolved Oxygen, Temperature, And Body Size On The Physiological Responses Of A Model Macrobenthic Polychaete Species, Capitella Teleta, Kelsey Burns Gillam

Dissertations

While the scientific community is in consensus that coastal systems are threatened by climate change, few climate change studies test the effects of more than one variable directly related to climate change. The dissolved oxygen (DO) levels of the ocean are currently subject to both global warming and eutrophication; 94% of all hypoxia zones are expected to experience >2°C increase by 2035. This dissertation aims to examine how a model organism responds to simultaneous thermal and DO stress involving four levels of DO (100%, 70%, 50%, and 20%) saturation and three temperatures (15°C, 20°C, and 25°C ...


An Analysis Of Morphometric Differentiation In Lake And River Populations Of The Emerald Shiner, Notropis Atherinoides, John J.V. Lang 2016 Buffalo State College

An Analysis Of Morphometric Differentiation In Lake And River Populations Of The Emerald Shiner, Notropis Atherinoides, John J.V. Lang

Biology Theses

Understanding mechanisms that account for phenotypic variation has been of interest to biologists since the advent of Darwin’s theory of evolution by natural selection. It is now understood that adaptive divergence is a key driving force of intraspecific differentiation. Further, differences in habitat (e.g., flow regime, prey regime) have been shown to drive adaptive divergence in fish. For instance, fish inhabiting faster flowing water generally exhibit more fusiform bodies than their lake counterparts. Similarly, the partitioning of benthic and pelagic morphs generally results in smaller heads with the latter. This study used geometric shape analysis to assess morphological ...


It’S Complicated: Does Food Web Structure Affect Detrital Processing In Streams?, Stephen H. Tentinger 2016 State University of New York College at Buffalo - Buffalo State College

It’S Complicated: Does Food Web Structure Affect Detrital Processing In Streams?, Stephen H. Tentinger

Biology Theses

Trophic cascades involve powerful feeding interactions that can alter the flow of energy and the abundance of species in an ecosystem. In western NY streams, the negative impacts of a new benthic invertivore, the round goby (Neogobius melanostomus) is altering benthic community structure and leaf litter decomposition. Streams with round gobies have a reduced abundance of shredders and slower leaf decay than streams without gobies. However, crayfish, as shredders of leaf litter, may be large or aggressive enough to avoid predation by round gobies. I used a 30-day full factorial field experiment with blocks to determine if round gobies affected ...


Insect Consciousness: Commitments, Conflicts And Consequences, Colin Klein, Andrew B. Barron 2016 Macquarie University, Australia

Insect Consciousness: Commitments, Conflicts And Consequences, Colin Klein, Andrew B. Barron

Animal Sentience: An Interdisciplinary Journal on Animal Feeling

Our target article, “Insects have the capacity for subjective experience,” has provoked a diverse range of commentaries. In this response we have collated what we see as the major themes of the discussion. It is clear that we differ from some commentators in our commitments to what subjective experience is and what the midbrain is capable of. Here we clarify where we stand on those points and how our view differs from some other influential perspectives. The commentaries have highlighted the most lively areas of disagreement. We revisit here the debates surrounding whether the cortex is essential for any form ...

Consciousness And Evolutionary Biology, Yew-Kwang Ng

Animal Sentience: An Interdisciplinary Journal on Animal Feeling

Reber’s axiom: “Any organism with flexible cell walls, a sensitivity to its surrounds and the capacity for locomotion will possess the biological foundations of mind and consciousness” does not seem to be supported by things we know and the logic of evolutionary biology. The latter leads to the conclusion that conscious species are flexible in their behavior (rather than in their cell walls), as argued in Ng (1995, 2016). Locomotion may be completely hard-wired and need not involve consciousness. It is hard enough to explain how consciousness could emerge in a sophisticated brain: Isn’t it a harder problem ...


The Difference Between Conscious And Unconscious Brain Circuits, Ezequiel Morsella, Zaviera Reyes 2016 San Francisco State University

The Difference Between Conscious And Unconscious Brain Circuits, Ezequiel Morsella, Zaviera Reyes

Animal Sentience: An Interdisciplinary Journal on Animal Feeling

Theoretical frameworks in which consciousness is an inherent property of the neuron must account for the contrast between conscious and unconscious processes in the brain and address how neural events can ever be unconscious if consciousness is a property of all neurons. Other approaches have sought answers regarding consciousness by contrasting conscious and unconscious processes and through investigating the complex interactions between the two kinds of processes, as occurs most notably in human voluntary action. In voluntary action, consciousness is associated most, not with motor control or low-level perceptual processing, but with the stage of processing known as action selection.



Resolving The Hard Problem And Calling For A Small Miracle, Arthur S. Reber 2016 University of British Columbia

Resolving The Hard Problem And Calling For A Small Miracle, Arthur S. Reber

Animal Sentience: An Interdisciplinary Journal on Animal Feeling

With the exception of the commentary by Key, the commentaries on Reber have a common feature: the commenters feel, with varying levels of enthusiasm, that there is at least some virtue in the core assumption of the Cellular Basis of Consciousness (CBC) theory that consciousness (or subjectivity or sentience) accompanies the earliest forms of life. The model has two important entailments: (a) it resolves the (in)famous Hard Problem by redirecting the search for the biochemical foundations of sentience away from human consciousness; and (b) it reduces the need for an emergentist miracle to a far simpler scale than is ...


Unconscious Higher-Order Thoughts (Hots) As Pre-Reflective Self-Awareness?, Rocco J. Gennaro 2016 The University of Southern Indiana

Unconscious Higher-Order Thoughts (Hots) As Pre-Reflective Self-Awareness?, Rocco J. Gennaro

Animal Sentience: An Interdisciplinary Journal on Animal Feeling

Rowlands argues that many nonhuman animals are “persons,” contrary to the prevailing orthodoxy which rests on a mistaken conception of the kind of self-awareness relevant to personhood. He argues that self-awareness bifurcates into two importantly different forms — reflective self-awareness and pre-reflective self-awareness — and that many animals can have the latter, which is sufficient for personhood. I agree that there is good reason to think that many animals can have pre-reflective self-awareness, but I think Rowlands is mistaken about its nature. His account runs the risk of leading to an infinite regress objection, and his notion of pre-reflective self-awareness actually sounds ...


Responding To Modern Flooding: Old English Place-Names As A Repository Of Traditional Ecological Knowledge, Richard L.C. Jones 2016 University of Leicester

Responding To Modern Flooding: Old English Place-Names As A Repository Of Traditional Ecological Knowledge, Richard L.C. Jones

Journal of Ecological Anthropology

Place-names are used to communicate Traditional Ecological Knowledge (TEK) by all indigenous, aboriginal and First Nations people. Here and for the first time, English place-names are examined through a TEK lens. Specifically, place-names formed in Old English—the language of the Anglo-Saxon—and coined between c. 550 and c. 1100 A.D., are explored. This naming horizon provides the basic name stock for the majority of English towns and villages still occupied today. While modern English place-names now simply function as convenient geographical tags Old English toponymy is shown here to exhibit close semantic parallels with many other indigenous place-names ...


The Psychological Concept Of “Person”, Kristin Andrews 2016 York University Animal Sentience

The Psychological Concept Of “Person”, Kristin Andrews

Animal Sentience: An Interdisciplinary Journal on Animal Feeling

Reluctance to overextend personhood seems to drive many of the skeptical responses in the first round of commentaries on Rowlands's target article. Despite Rowlands’s straightforward Response that we already accept some nonhumans as persons, there is still hesitation to accept that other nonhuman animals are persons. Rowlands's argument is sound but the skeptics don’t accept the Lockean notion of person. The metaphysical sense of person is a psychological one, however, and psychological properties grant one moral status according to many ethical theories.

P-04 Cavan Burren 2015 Project, Rhonda Root, Robin Johnson, Ariel Solis, Abelardo Rivas

Ariel Solis

The Cavan Burren is a plantation forest within the Marble Arch Caves UNESCO Global Geopark overlay along the Republic of Ireland and Northern Ireland border. The exposure of Cavan Burren’s "relict landscape" resulted from a 2012 partial clear fell. Our multidisciplinary team of researchers in architecture, technology, ecology, fine arts, and archaeology investigated domestic architecture reflected in three stone configurations: circular/semicircular sites, rectangular sites, and tomb structures. We also investigated human action on pedestal boulders (PBs), which had been modified by sculpting, splitting, and cutting away. Our first goal was to show human action on structures by using ...

Reproductive Schedule Of The Silver Shiner (Notropis Photogenis) In The Flint River Of Alabama, Kelly Hodgskins, Stephanie Greenleaf, Jonathan Hillman, Bruce Stallsmith 2016 University of Alabama in Huntsville

Reproductive Schedule Of The Silver Shiner (Notropis Photogenis) In The Flint River Of Alabama, Kelly Hodgskins, Stephanie Greenleaf, Jonathan Hillman, Bruce Stallsmith

Southeastern Fishes Council Proceedings

Many river-dwelling species of fish are dependent upon and stimulated by fluctuations in river flow for successful reproduction. This is especially true of pelagophils, a reproductive guild whose eggs and larvae require free drifting on river currents for several days. Notropis photogenis (Silver Shiner) is a rheophilic species with a broad distribution from Ontario to the southeastern United States including northern tributaries to the Tennessee River in Alabama. Little is known of its reproductive biology. The purpose of this study was to describe aspects of reproductive biology such as timing and pattern of ovarian development and oocyte maturation of N ...


Consciousness And The Unity Of Mind, Mark Rowlands 2016 University of Miami

Consciousness And The Unity Of Mind, Mark Rowlands

Animal Sentience: An Interdisciplinary Journal on Animal Feeling

Several types of objection have been raised against the arguments I presented in my target article, “Are animals persons?” Among the objections are the following: (1) the claim that animals are persons is of little significance, (2) my use of the Lockean conception of the person is questionable, (3) whether a creature qualifies as a person is a matter of social construction rather than objective fact, (4) reflective consciousness is more important than I realize, (5) my reliance on implicit self-awareness in the account of personhood is ill-advised, (6) my account entails that too many creatures qualify as persons, and ...


The North American Sea Ducks: Their Biology And Behavior, Paul A. Johnsgard 2016 University of Nebraska-Lincoln

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

Zea E-Books

The 21 species of sea ducks are one of the larger subgroups (Tribe Mergini) of the waterfowl family Anatidae, and the 16 species (one historically extinct) that are native to North America represent the largest number to be found on any continent, and also the largest number of endemic sea duck species native to any continent.

Although generally not important as game birds, the sea ducks include some economically important birds such as the eiders, the basis for the Arctic eiderdown industry and a historically important food source for some Native American cultures. They also include what is probably the ...


Insects: Still Looking Like Zombies, Christopher S. Hill 2016 Brown University

Insects: Still Looking Like Zombies, Christopher S. Hill

Animal Sentience: An Interdisciplinary Journal on Animal Feeling

In arguing that insect brains are capable of sentience, Klein & Barron rely heavily on Bjorn Merker’s claim that activity in the human mid-brain is sufficient for conscious experience. I criticize Merker’s claim by pointing out that the behaviors supported by midbrain activity are much more primitive than the ones that appear to depend on consciousness. I raise a similar objection to Klein & Barron’s contention that insect behaviors are similar to behaviors that manifest consciousness in human beings. The similarity is weak. I also respond to the related view that integrative activity in mid-brain structures is sufficient to ...
