Determining Critical Internesting And Foraging Habitats For The Conservation Of Sea Turtles In Gabon, Africa Using Satellite Tracking And Stable Isotope Analysis, Tiffany M. Dawson 2017 Old Dominion University

Determining Critical Internesting And Foraging Habitats For The Conservation Of Sea Turtles In Gabon, Africa Using Satellite Tracking And Stable Isotope Analysis, Tiffany M. Dawson

Biological Sciences Theses & Dissertations

Understanding the horizontal and vertical habitat of olive ridley sea turtles (Lepidochelys olivacea), a threatened species, is critical for determining regions of protection that may effectively reduce bycatch, the largest threat to this species. Satellite transmitters were used to determine the movement and dive behavior of 21 female olive ridley turtles tagged in Pongara National Park, Gabon during the 2012, 2013, and 2015 nesting seasons. A switching state space model was used to filter the tracking data and categorize the internesting and post-nesting movements. Gridded utilization distribution (UD) home range analysis of tracking data revealed that the entire core habitat …


The Effect Of "Casitas" On Lobster Biology And Fishery Sustainability In The Bahamas, Lester George Gittens 2017 Old Dominion University

The Effect Of "Casitas" On Lobster Biology And Fishery Sustainability In The Bahamas, Lester George Gittens

Biological Sciences Theses & Dissertations

“Casitas” (artificial table-like structures) are a commercial fishing gear used to harvest Caribbean spiny lobster (Panulirus argus) in the Caribbean and in The Bahamas, where lobster is the most valuable fishery. Yet, casitas are largely unregulated in The Bahamas and they may threaten fishery sustainability through alteration of lobster growth, disease, or mortality rates and due to insufficient information concerning their number and location. Focusing on the lobster fishery in The Bahamas, my objectives were to: (1) investigate the mortality, growth, and susceptibility to disease of lobsters collected in casitas compared to wooden traps and those living in …

The Highlands–Glades subpopulation (HGS) of Florida, USA, black bears (Ursus americanus floridanus) is small, genetically depauperate, and resides primarily within the endangered Lake Wales Ridge ecosystem, which has lost >85% of native habitat to land development. Habitat loss can reduce availability of critical natural foods and cause bears to increase reliance on anthropogenic foods (i.e., human-sourced); lands supporting the HGS are expected to lose >50% of remaining Florida black bear habitat in coming decades. We used scat analysis to describe seasonal food habits, investigate potential dietary responses to food shortages, and inform habitat conservation and human–bear conflict management. …

The common vampire bat, Desmodus rotundus, ranges from South America into northern Mexico in North America. This sanguivorous species of bat feeds primarily on medium to large-sized mammals is known to rely on livestock as primary prey. Each year, there are hotspot areas of D. rotundus-specific rabies virus outbreaks that lead to the deaths of livestock and economic losses. Based on incidental captures in our study area, which is an area of high cattle mortality from D. rotundus transmitted rabies, it appears that D. rotundus are being caught regularly in areas and elevations where they previously were thought to be …

Profiling Bat Activity And Species Presence In Managed Longleaf Pine Landscapes, Margaret Hunt 2017 Kennesaw State University

Profiling Bat Activity And Species Presence In Managed Longleaf Pine Landscapes, Margaret Hunt

Master of Science in Integrative Biology Theses

Restoration of native flora or reintroduction of at-risk fauna includes management practices that while encouraging presence and proliferation of target species, may adversely affect non-focal species. An endemic ecosystem undergoing restoration within the southeastern U.S. is that of the longleaf pine (Pinus palustris). Bats inhabit key ecological niches in forest ecosystems, including the longleaf pine ecosystem, and can be indicators of ecosystem condition. This study investigated the effects of current forest management practices and landscape management history on bat species presence and activity levels within habitat undergoing longleaf pine restoration. We deployed bat detectors in two wildlife management …

Some Corrections And Remarks Regarding The Nomenclature Of Neotropical Athyreini, Passalini, Phanaeini, Rutelini, Cyclocephalini, Dynastini And Oryctini (Coleoptera: Scarabaeoidea), Auke J. Hielkema 2017 Paramaribo, Suriname

Some Corrections And Remarks Regarding The Nomenclature Of Neotropical Athyreini, Passalini, Phanaeini, Rutelini, Cyclocephalini, Dynastini And Oryctini (Coleoptera: Scarabaeoidea), Auke J. Hielkema

Insecta Mundi

A number of nomenclatural issues regarding Neotropical Scarabaeoidea are addressed. Athyreus soesilae Makhan, 2008 is synonymized with Neoathyreus (Neoathyreus) excavatus (Laporte, 1840) (Geotrupidae: Bolboceratinae: Athyreini). Scalmus Zang, 1905 is replaced with its senior synonym Neleuops Kuwert, 1891, nec Neleurops Kuwert, 1891, and the four species it presently contains are thus transferred to Neleuops (Passalidae: Passalinae: Passalini). The spelling of the name Oxysternon oberthueri Olsoufieff, 1924, a junior synonym of Oxysternon (Oxysternon) conspicillatum (Weber, 1801), is fixed (Scarabaeidae: Scarabaeinae: Phanaeini). The year of description of Oxysternon (Oxysternon) festivum (Linnaeus, 1758) is corrected, its existing lectotype invalidated, and a new lectotype designated …

Predicting The Impact Of Sea Level Rise On The Distribution Of Phragmites Australis And Spartina Alterniflora And Changes In Community Compositions In Tidal Freshwater Marshes Of James City County, Va, Abbey Humphreys 2017 College of William and Mary

Predicting The Impact Of Sea Level Rise On The Distribution Of Phragmites Australis And Spartina Alterniflora And Changes In Community Compositions In Tidal Freshwater Marshes Of James City County, Va, Abbey Humphreys

Dissertations, Theses, and Masters Projects

With ongoing sea level rise (SLR), tidal freshwater marshes (TFMs) eventually will be flooded with more brackish water. The impact of more water and salt on the plant community of TFMs, however, is unknown. With SLR, both the invasive reed Phragmites australis and the native salt marsh grass Spartina alterniflora could become dominant species in TFMs. I am looking at determining how increases in salinity and inundation caused by sea level rise will impact the relative distribution of Phragmites and Spartina in tidal freshwater marshes in Southeastern Virginia. Using GIS, I summarized past expansion patterns by mapping the current and …

Spatial And Temporal Variation In Mangrove Distribution (1950-2014) In Tampa, Florida Usa, Carolyn Cheatham Rhodes

USF Tampa Graduate Theses and Dissertations

I carried out an observational study of historic high resolution aerial imagery spanning six decades (1950-2014) to identify recent and historic spatial extent of mangrove forests, within the municipal boundaries of the City of Tampa, Florida USA. My objectives were to map mangrove distribution and spatial extent and any change or patterns of change discernable. I observed variable patterns of change and rates of expansion varied between sites spatially as well as within sites between time intervals. I found notable changes in mangrove extent in the Tampa from historic and modern aerial imagery for the ~64-year period between 1950 and …


Analysis Of Population Structure In A California Newt (Taricha Torosa) Metapopulation, Jessica Vincent 2017 Western Kentucky University

Analysis Of Population Structure In A California Newt (Taricha Torosa) Metapopulation, Jessica Vincent

Mahurin Honors College Capstone Experience/Thesis Projects

As anthropogenic influences take an ever-increasing toll on the environment, understanding how environmental change affects species is paramount. Concern regarding decline in amphibian populations has spurred research examining the effects of habitat change on the dynamics of populations at landscape levels. One important goal is to understand how gene flow among populations is affected by changes in habitat. Biologists need to consider the relationship between gene flow and habitat alterations so that movements among individual breeding ponds can be maintained over time, reducing risk of local extinction events. This study focuses on patterns of gene flow among thirteen populations of …


The Second Record Of A Relict Akrav Israchanani Levy, 2007 (Scorpiones: Akravidae) From Levana Cave, Israel, Victor Fet, Michael E. Soleglad, Sergei L. Zonstein, Israel Naaman, Shlomi Lubaton, Boaz Langford, Amos Frumkin 2017 Marshall University

The Second Record Of A Relict Akrav Israchanani Levy, 2007 (Scorpiones: Akravidae) From Levana Cave, Israel, Victor Fet, Michael E. Soleglad, Sergei L. Zonstein, Israel Naaman, Shlomi Lubaton, Boaz Langford, Amos Frumkin

Euscorpius

We report the remnants of five new scorpion specimens discovered dead in Levana Cave in Israel in December 2015. We confirm that they belong to the relict scorpion Akrav israchanani Levy, 2007 (Akravidae), famously described from the neighboring Ayyalon Cave, also from dead specimens. The details of morphology of the new specimens are given; they match completely the characters of A. israchanani redescribed by Fet, Soleglad & Zonstein (2011). This second record indicates a wider distribution of this unique cave scorpion, which, however, is extinct in both caves. There is still no evidence that live populations of this species exist.


Ethical Theories And Perspectives On End-Of-Life Decisions, Lauren Skelton 2017 Abilene Christian University

Ethical Theories And Perspectives On End-Of-Life Decisions, Lauren Skelton

Dialogue & Nexus

This paper approaches several different ethical theories to see how they interact with the issue of withdrawing and withholding life-sustaining care. After the theories of Utilitarianism, Kantian and Prima Facie Deontology, Virtue Ethics, and Evolutionary Ethics are explored at length, Deontological theories are proven to be the best decision-making guide from the perspective of both patients and those in policy-making positions. When used together, Kantian and Prima Facie Deontology offer the overall best combination of ethical instruction and personal freedom.


Ecofeminism: The Path Towards Healing The Earth, Jamie Thompson 2017 Abilene Christian University

Ecofeminism: The Path Towards Healing The Earth, Jamie Thompson

Dialogue & Nexus

The concept of the patriarchy, or any concept in which one group dominates another, is inseparable from the formation of human kind’s domination of nature. This domination of nature has led to the current the ecological crisis humanity faces. Those who deny climate change can admit to the massive amounts of pollution, trash, and deforestation. Despite this worsening economic crisis, those in power have been slow to react. Women can ultimately provide and lead the movement to solve this ecological crisis through the growing movement of Ecofeminism. In the philosophy of Ecofeminism, individuals recognize and reject western dualistic thinking that …


The Origins Of Morality, Paulina Sanchez 2017 Abilene Christian University

The Origins Of Morality, Paulina Sanchez

Dialogue & Nexus

In modern society, there exists a standard for moral conduct that seems to reign universal over many societies of people. Pinpointing the origins of morality, however, can become problematic because of how one approaches what morality is and what its purpose is in society. Psychologists may point out the social constructs and norms that allow for morality to unfold. Evolutionary biologists may give evidence of human-related species that have developed similar behavioral standards. A Christian theologian may look to scripture in explaining a Creator who ordained that all abide by the standards of conduct most pleasing to this deity. Which …
