Alfred Russel Wallace Notes 23: The Jersey Devil, And Friends, Charles H. Smith
Alfred Russel Wallace Notes 23: The Jersey Devil, And Friends, Charles H. Smith
Faculty/Staff Personal Papers
For nearly three hundred years reports have surfaced of a purported cryptid form known as the ‘Jersey devil.’ In this work an interpretation of the goals of biogeography is given, and how this field can be related to such alleged phenomena, as well as to some of the ideas of Alfred Russel Wallace (1823-1913) that seem to find their origin in the writings of Benedict de Spinoza (1632-1677).
Analysis Of Interdunal Wetlands And Ecosystem Dynamics Using Uas And Obia In Ludington State Park, Michigan, Claire Gilbert
Analysis Of Interdunal Wetlands And Ecosystem Dynamics Using Uas And Obia In Ludington State Park, Michigan, Claire Gilbert
Masters Theses
The Great Lakes sand dunes are the world's largest freshwater dune complex. There is a functional relationship between coastal wetlands and freshwater sand dune, referred to as interdunal wetlands. Interdunal wetland systems are highly dynamic and change dramatically seasonally and annually. Using geographic information systems (GIS) and unoccupied aerial systems (UAS), this thesis project is focused on understanding the spatial distribution of sparse and dense vegetation, and abiotic influence such as distance to coast, slope, and aspect influence interdunal wetland stability within a Great Lakes shoreline dune system. Object-based image analysis (OBIA) classification results extracted meaningful vegetation densities of growth …
A Tale Of Two Species: Black-Tailed And White-Tailed Prairie Dog Biogeography From The Last Interglacial To 2070, April Dawn Bledsoe
A Tale Of Two Species: Black-Tailed And White-Tailed Prairie Dog Biogeography From The Last Interglacial To 2070, April Dawn Bledsoe
Electronic Theses and Dissertations
Ecological niche models (ENMs) were created for White-tailed and Black-tailed prairie dogs and projected into the Last Interglacial (LI), the Last Glacial Maximum (LGM), and mid-Holocene (mid-H) to discern possible past suitable habitat for both species. Additionally, ENMs were projected into the future year 2070 representative concentration pathways (RCPs) 2.6 and 8.5 to discern how climate change may affect future habitat suitability. Kernel density estimations, minimum convex polygons, and median distribution centers of White-tailed and Black-tailed occurrence records were examined between time-periods to discern the effects of anthropogenic westward expansion on both species’ distributions. Current ENMs were constructed from commonly …
Adding Phylogenies To Qgis And Lifemapper For Evolutionary Studies Of Species Diversity, Jeffery A. Cavner, Aimee M. Stewart, Charles J. Grady, James H. Beach
Adding Phylogenies To Qgis And Lifemapper For Evolutionary Studies Of Species Diversity, Jeffery A. Cavner, Aimee M. Stewart, Charles J. Grady, James H. Beach
Free and Open Source Software for Geospatial (FOSS4G) Conference Proceedings
Phylogenetic data from the “Tree of Life” have explicit spatial and temporal components when paired with species distribution and ecological data for testing contributions to biological community assembly at different geographic scales of species interaction. Important questions in biology about the degree of niche suitability and whether the history of a community’s assembly for an area can affect whether the species in a community are more or less phylogenetically related can be answered using several different spatially-filtered measures of phylogenetic diversity. Phylogenetic analyses which support the description of ecological processes are usually achieved in a handful of software libraries that …
Using Remote Sensing And Biogeographic Modeling To Understand The Oak Savannas Of The Sheyenne National Grassland, North Dakota, Usa, Mandira Sigdelphuyal
Using Remote Sensing And Biogeographic Modeling To Understand The Oak Savannas Of The Sheyenne National Grassland, North Dakota, Usa, Mandira Sigdelphuyal
Electronic Theses and Dissertations
Oak savannas are valuable and complex ecosystems that provide multiple ecosystem goods and services, including grazing for livestock, watershed regulation, and recreation. These ecosystems of the woodland-prairie ecoregion of the Midwestern United States are, however, in danger of disappearing. The Sheyenne National Grassland, North Dakota, a protected Prairie grassland-savanna, is a representative of such rare habitats, where oak savanna is found at the landscape scale. In this research, I map the distribution patterns of oak savanna in the Sheyenne using a combination of remote sensing and geospatial datasets, including landscape topography, soils, and fire disturbance. Further, I interpret the performance …
A Research Framework For The Geographic Study Of Exotic Pet Mammals In The Usa, Gabrielle C. Tegeder
A Research Framework For The Geographic Study Of Exotic Pet Mammals In The Usa, Gabrielle C. Tegeder
Department of Geography: Dissertations, Theses, and Student Research
Exotic animals are not well-represented in geographic studies, even in the emerging sub-field of animal geography. With the dearth of exotic animal studies, and the relevance of exotic pets in the public consciousness and in the news, a basic, introductory study such as this is necessary to begin examining the myriad ways in which exotic pets intersect with, and have influence in, both the site and situation of modern human-oriented environments.
Exotic pet attack incidents and both state and federal laws regarding the private ownership of exotic mammals as pets were examined in detail within the scope of this research. …
Integrating, Developing, And Testing Methods To Generate More Cohesive Approaches To Biogeographic Inference, Mallory Elizabeth Eckstut
Integrating, Developing, And Testing Methods To Generate More Cohesive Approaches To Biogeographic Inference, Mallory Elizabeth Eckstut
UNLV Theses, Dissertations, Professional Papers, and Capstones
As a fundamental component of the developing discipline of conservation biogeography, broadscale analyses of biotic assembly and disassembly across multiple temporal and spatial scales provide an enhanced understanding of how geologic transformations and climate oscillations have shaped extant patterns of biodiversity. As with any scientific field, there are limitations in the case of biogeographic historical reconstructions. Historical reconstructions are only as robust as the theoretical underpinnings of the methods of reconstruction (including data collection, quality, analysis, and interpretation). Nevertheless, historical reconstructions of species distributions can help inform our understanding of how species respond to environmental change.

Wallace: The Review, And Wallace: The Preview, Charles H. Smith
Wallace: The Review, And Wallace: The Preview, Charles H. Smith
DLPS Faculty Publications
In this essay commemorating the one hundred year anniversary of his death, Alfred Russel Wallace (1823–1913) is remembered for his main contributions to biogeography, and pointed to as a possible source of inspiration for future work in that field. As one of the science’s “fathers,” Wallace established both methods for study and a long-lived geographical systemization of animal distribution patterns. His efforts, moreover, may yet have the potential to inspire further new studies in the subject.

Some Biogeographers, Evolutionists And Ecologists: Chrono-Biographical Sketches, Charles H. Smith, Joshua Woleben, Carubie Rodgers
DLPS Faculty Publications
Each name in the following list of naturalists is linked to a corresponding capsule "chrono-biographical" sketch of that individual prepared by the authors. Coverage extends from approximately 1950 backward in time as far as the eighteenth century; figures from all over the world are included (though there is admittedly a decided Anglo-American bias). The target subject here is biogeography, but this being a broad field there are many persons on the list who are better known as climatologists, zoologists, botanists, ecologists, oceanographers, paleontologists, etc.--in other words, who made their main reputations in cognate disciplines.

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298
FloraGREIF is an internet accessible information system providing taxonomic, phytogeographic and ecological information on Mongolia’s flora in terms of descriptions, high-resolution plant images and an interactive WebGIS application. Organised along an updated checklist of the approx. 3000 Mongolian vascular plants that serves as a taxonomic backbone, information is split into the taxon level, referring to plant species, and the record level, referring to record or a collected plant specimen. At the latter level, images of living plants, scans of herbarium sheets, habitat photos and further notes can be found. Both data levels are linked by the name of the respective …
Systematics, Biogeography And Leaf Anatomy And Architecture Of Bursera Subgen. Bursera (Burseraceae) In The Greater Antilles And The Bahamas, María Cristina Martínez-Habibe
Systematics, Biogeography And Leaf Anatomy And Architecture Of Bursera Subgen. Bursera (Burseraceae) In The Greater Antilles And The Bahamas, María Cristina Martínez-Habibe
CGU Theses & Dissertations
This dissertation presents a comprehensive study on the origin and evolutionary relationships of the species of Bursera in Cuba, Hispaniola, Jamaica and the Bahamas. The goals of the first chapter were to test monophyly of the group, revisit a recent transfer of two species of Bursera to Commiphora, and place recently discovered mainland species using the reconstructed phylogenies. Additionally, divergence estimations using fossils were used as independent tests of several hypotheses regarding the arrival of the modern biota to the Greater Antilles and Bahamas (GAB). I conclude that all endemic taxonomic entities of the genus in this region belong …

Introduction: One Hundred Years Of Natural History In Turkmenistan, Victor Fet
Introduction: One Hundred Years Of Natural History In Turkmenistan, Victor Fet
Biological Sciences Faculty Research
As part of the famous “Great Game” between the Russian and British Empires in Central Asia, Turkmenistan was the last colonial prize of the Russian tsars; its delineation from Afghanistan was completed only in the 1890s. The Russian Empire’s Transcaspian Region (Zakaspiiskaya Oblast) was roughly what Turkmenistan is today; its neighbors were the semi-independent emirate of Bokhara to the east and khanate of Khiva to the north, both remnants of medieval Muslim empires.
This book combines the results of basic scientific research in biogeography and ecology; its purpose is to give a fairly comprehensive account of the nature of Turkmenistan. …
Historical Biogeography: Geography As Evolution, Evolution As Geography, Charles H. Smith
Historical Biogeography: Geography As Evolution, Evolution As Geography, Charles H. Smith
DLPS Faculty Publications
Despite a number of advances in recent years, biogeography remains a field with a poorly developed philosophical core. As a result, its historical and ecological sides remain as isolated from one another as ever. In this essay I argue that a more unified approach to biogeographic studies will become possible only when workers realise that it is necessary to reject absolute space, "geography as handmaiden" approaches to distribution problems in favour of structuralist models compatible with both probabilistic spatial interaction and deterministic phylogenetic kinds of thinking. Pros and cons of regionalist, vicariance, and panbiogeographic approaches are weighed in this regard; …
