A Role For Natural Resource Social Science In Biodiversity Risk Assessment, Philip J. Nyhus, Frances R. Westley, Robert C. Lacey, Philip S. Miller
A Role For Natural Resource Social Science In Biodiversity Risk Assessment, Philip J. Nyhus, Frances R. Westley, Robert C. Lacey, Philip S. Miller
Faculty Scholarship
Biologists have made considerable progress in developing realistic simulation models to predict extinction risks for threatened species. Social scientists have to date had a more limited role in these efforts. This limited involvement comes despite the growing acknowledgment by population biologists and simulation modelers that this additional input is necessary for these models to accurately reflect the impact of humans and human-dominated landscapes on wildlife populations. We argue that collaborations among social and biological scientists can provide unparalleled opportunities to develop new conceptual and simulation tools for biodiversity risk assessment. One challenge is that while the value of interdisciplinary research …
Determining The Genetic Distances Between Sub-Populations Of Aneides Aeneus In The Westvāco Wildlife And Ecological Research Forest, Andrew Nicholas Johnson
Determining The Genetic Distances Between Sub-Populations Of Aneides Aeneus In The Westvāco Wildlife And Ecological Research Forest, Andrew Nicholas Johnson
Theses, Dissertations and Capstones
Aneides aeneus, the Green Salamander, is a plethodontid species ranging from southern Pennsylvania to central Alabama and from eastern Mississippi to Maryland. Populations of Green Salamanders most often inhabit cliffs and rocky outcrops which are moist but not wet and shaded. The animal is listed as a species of special concern by the West Virginia Division of Natural Resources Wildlife Diversity Program. Genetic and reproductive isolation due to strict habitat preferences of the Green Salamander could be a factor in the decline of the species. Seventeen tissue samples were retrieved from five sites within the Westvāco Wildlife and Ecosystem …
Canis Lupus Cosmopolis: Wolves In A Cosmopolitan Worldview, William S. Lynn
Canis Lupus Cosmopolis: Wolves In A Cosmopolitan Worldview, William S. Lynn
Human and Animal Bonding Collection
The subject of wolf recovery in North America sparks heated controversy, both for and against. This paper explores how this subject is informed by cosmopolitan worldviews. These worldviews pull nature and culture into a common orbit of ethical meaning, with implications for the normative relationships that ought to pertain in landscapes shared by people and wolves. This theoretical outlook is illustrated using the controversy over wolves in the northeastern region of the United States. I conclude with a set of reflections on theorizing the cosmopolis, the interpretation of cosmopolitan landscapes, and living with cosmopolitan wolves.
Resolving Conflicts Between People And Canada Geese: The Need For Comprehensive Management Approaches, John Hadidian
Resolving Conflicts Between People And Canada Geese: The Need For Comprehensive Management Approaches, John Hadidian
Wildlife Population Management Collection
Canada geese have become established and are now numerous enough in many urban and suburban areas that conflicts with humans have become frequent. Although potential threats to human health are often cited as a justification to manage goose populations, currently available science suggests that this is not a serious issue. This leaves the primary concern as one of aesthetics– people do not like having to deal with what can sometimes be copious amounts of goose droppings. Animal welfare interests have questioned the humaneness of different roundup and killing programs, and advocated non-lethal approaches and egg addling. Both approaches currently are …

The “Nuisance” Wildlife Control Industry: Animal Welfare Concerns, John Hadidian, Laura J. Simon, Michele R. Childs
Wildlife Population Management Collection
The recent and rapid growth of the private “nuisance” wildlife control industry follows the unparalleled current period of urban and suburban expansion. Nuisance wildlife control businesses range from simple home-based services to sophisticated franchised businesses. The nuisance wildlife control operator may hold an advanced degree in the wildlife sciences, or simply be an entrepreneur without formal education or even background experience in wildlife. State and federal agencies may participate directly or indirectly in nuisance wildlife control, in activities ranging from dissemination of advice or information to actual participation in programs that may lead to removal of animals. Naturally, all of …
Fisheries Research Report No. 137 - Annual Report On The Monitoring Of The Recreational Marron Fishery In 2000, With An Analysis Of Long-Term Data And Changes Within This Fishery, Brett Molony, Chris Bird
Fisheries Research Report No. 137 - Annual Report On The Monitoring Of The Recreational Marron Fishery In 2000, With An Analysis Of Long-Term Data And Changes Within This Fishery, Brett Molony, Chris Bird
Fisheries Research Reports
This report presents the data from the 2000 season and compares the results with previous records. Although the 2000 marron season was relatively successful compared to the 1999 season it was still modest in terms of the historical records. Further, the recreational marron fishery continues to be declining in terms of catch rate, CPUE and other indicators derived from four data sources. The discussion highlights the variable nature of marron populations and the possible causes of the very different population structures of marron within the fishery. Further, possible reasons for the long-term decline of the marron fishery are discussed. It …
Status Of The Small-Mouthed Salamander, Ambystoma Texanum (Mathes) In West Virginia, Robert Fiorentino
Status Of The Small-Mouthed Salamander, Ambystoma Texanum (Mathes) In West Virginia, Robert Fiorentino
Theses, Dissertations and Capstones
Over the past 60 years little natural history information on Ambystoma texanum (Small-mouthed Salamander) has been collected in West Virginia, the eastern most location for the species. Three historical breeding populations of A. texanum have been documented in the state, but salamanders from 2 of these locations have not been documented for the past 30 years. Searches of historical sites and favorable habitat in Mason, Jackson, and Wood counties yielded no evidence for the presence of A. texanum, except for the known breeding site in Wood County. Information on time of breeding and egg development was collected at the Wood …
Colony Composition And Demographics Of Beavers In Illinois, Stanley T. Mctaggart
Colony Composition And Demographics Of Beavers In Illinois, Stanley T. Mctaggart
Masters Theses
Beavers (Castor canadensis) have been extensively studied throughout North America, but little research has been conducted on this species in Illinois and the Midwest. Beavers exhibit wide variations in colony composition and demographics over their broad geographic range, so regional research is important for sound management. The objectives of this study were to investigate the: (1) typical composition of beaver colonies in Illinois; (2) reproductive potential of female beavers in Illinois; (3) sex-age composition of beaver populations in Illinois; and (4) efficacy of night-vision surveys versus removal trapping for estimating colony size. This study was conducted during the 1999-00 and …

Aerial counts were made to compare angling and recreational boating data with ground count data. Recreational users spent an estimated 745,303 hours on the Missouri River survey reach during 2000. Fishing accounted for an estimated 458,749 hours, or 62% of …
An Examination Of The Mitoura (Lycaenidae) In The Southeastern United States: With The Description Of A New Subspecies Of Mitoura Hesseli, Ronald R. Gatrelle
An Examination Of The Mitoura (Lycaenidae) In The Southeastern United States: With The Description Of A New Subspecies Of Mitoura Hesseli, Ronald R. Gatrelle
The Taxonomic Report of the International Lepidoptera Survey
Four subspecies of Mitoura grynea occur in the United States east of the Mississippi River. The nominate subspecies occupies this entire area except for Florida and the coastal regions of South Carolina and Georgia. Mitoura g. grynea is usually associated with Juniperus virginiana. A neotype is designated for Lycus gryneus from Aiken County, South Carolina. Mitoura grynea smilacis is endemic to the southeastern coastal islands and coastal mainland from about Brunswick Georgia north to the Santee River delta of South Carolina. Smilacis’ range corresponds to that of Juniperus silicicola in that area. A neotype is designated for …
An Examination Of Southeastern U. S. Satyrium (Lycaenidae: Theclinae), Part Two: The Identification And Delimitation Of Nominate Satyrium Liparops And The Description Of A New Subspecies From West Central Peninsular Florida, Ronald R. Gatrelle
The Taxonomic Report of the International Lepidoptera Survey
The name Satyrium liparops liparops has traditionally been applied to all liparops populations from eastern Georgia southward. This tradition is shown to be in error. The type locality of nominate liparops is restricted by original description to Screven County, Georgia. A neotype is designated from Screven County and deposited in the Museum of the Hemispheres (MOTH) collection Goose Creek, South Carolina. The range of nominate liparops is projected to be from coastal South Carolina across the far southern United States (including the Florida panhandle) and into Texas. The population in west central peninsular Florida is described as new subspecies S …

A Cytochrome-B Perspective On Passerina Bunting Relationships, John Klicka, Adam J. Fry, Robert M. Zink, Christopher W. Thompson
A Cytochrome-B Perspective On Passerina Bunting Relationships, John Klicka, Adam J. Fry, Robert M. Zink, Christopher W. Thompson
Ornithology Program (HRC)
We sequenced the complete mitochondrial cytochrome-b gene (1,143 nucleotides) for representatives of each species in the cardinalid genera Passerina (6 species), Guiraca (1 species), and Cyanocompsa (3 species), and used a variety of phylogenetic methods to address relationships within and among genera. We determined that Passerina, as presently recognized, is paraphyletic. Lazuli Bunting (P. amoena) is sister to the much larger Blue Grosbeak (Guiraca caerulea). Indigo Bunting (P. cyanea) and Lazuli Bunting are not sister taxa as generally thought. In all weighted parsimony trees and for the gamma-corrected HKY tree, Indigo Bunting is …

An Examination Of Southeastern U.S. Satyrium (Lycaenidae: Theclinae), Part One: An Obscure New Subspecies Of Satyrium Edwardsii, Ronald R. Gatrelle
The Taxonomic Report of the International Lepidoptera Survey
Satyrium edwardsii meridionale is described as a new subspecies from Aiken County, South Carolina, United States. This scarce colony is the southeasternmost known population of this butterfly in the United States. It was discovered by the author (Ronald R. Gatrelle) in 1990 near Aiken State Park in Aiken County, South Carolina. This site is in South Carolina’s upper Coastal Plain in the southern part of the state adjacent to Georgia. It is known from only one male and one female at the type locality. Because it was known from only one pair, the author thought it best to wait until …
Clarification Of And Comments On Northern Speyeria Hydaspe Subspecies (Lepidoptera: Nymphalidae), Norbert G. Kondla
Clarification Of And Comments On Northern Speyeria Hydaspe Subspecies (Lepidoptera: Nymphalidae), Norbert G. Kondla
The Taxonomic Report of the International Lepidoptera Survey
The geographic distribution and use of three northern Speyeria hydaspe subspecies names is reviewed. This is necessary due to literature errors about the type locality of subspecies rhodope (Edwards, 1874). The correct placement of the rhodope type locality renders the name S. hydaspe sakuntala (Skinner, 1911) of interior British Columbia as a junior synonym of S. hydaspe rhodope. The name S. hydaspe minor (McDunnough, 1927) is available for the coastal populations by those who recognize these as different from those of the interior.
Natural History And Roosting Ecology Of The Eastern Pipistrelle, Pipistrellus Subflavus, Jacques Pierre Veilleux
Natural History And Roosting Ecology Of The Eastern Pipistrelle, Pipistrellus Subflavus, Jacques Pierre Veilleux
All-Inclusive List of Electronic Theses and Dissertations
A study concerning the natural history and roosting ecology of the eastern pipistrelle, Pipistrellus subtlavus, was conducted from 1997 to 2000, in southern Vigo County, Indiana. 111 Females began forming pre-maternity colonies during early May, and parturition began during late June. Pre-maternity colonies averaged 3.7 ± 1.9 individuals, and maternity colonies averaged 4.4 ± 2.4 individuals. Young pipistrelles first became volant during the third and fourth weeks of July. Pipistrelles were located in 59 roost trees. All roosts were located in foliage, either in clusters of dead leaves (n = 40) or in live foliage (n = 19). Oaks (Ouercus …
The Taxonomic Rank Of Spizella Taverneri: A Response To Mayr And Johnson, John Klicka, Robert M. Zink, Jon C. Barlow, W. Bruce Mcgillivray, Terry J. Doyle
The Taxonomic Rank Of Spizella Taverneri: A Response To Mayr And Johnson, John Klicka, Robert M. Zink, Jon C. Barlow, W. Bruce Mcgillivray, Terry J. Doyle
Ornithology Program (HRC)
Mayr and Johnson suggest that Spizella taverneri should be a subspecies of the biological species S. breweri, because it is possibly not reproductively isolated. We originally concluded that evidence from mitochondrial DNA sequences, habitat preferences, timing of breeding, vocalizations, and morphology supported the recognition of S. taverneri as a phylogenetic and biological species. Nothing in the commentary by Mayr and Johnson causes us to change that conclusion. We believe that it is probable that these two allopatric taxa are isolated. Contrary to Mayr and Johnson, we believe that more information is given by ranking S. taverneri as a species, because …
Effectiveness Of Earthen Escape Ramps In Reducing Big Game Mortality In Utah, Mary L. Hammer
Effectiveness Of Earthen Escape Ramps In Reducing Big Game Mortality In Utah, Mary L. Hammer
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
One-way escape gates and earthen escape ramps are structures used to enable deer to exit the highway right-of-way along fenced roads. I compared the use of one-way escape gates and earthen escape ramps by mule deer on two highways in Utah to determine if deer exhibited a preference for either structure. Results showed that earthen escape ramps were used by mule deer 8-11 times more frequently than one-way gates. Highway mortality data suggest that the installation of the escape ramps likely reduced mortality of mule deer in both study locations, because we could not attribute reductions in mortality to decreased …

The Lancelin Island Lagoon is a small area of reef habitat on the western side of Lancelin Island and a popular snorkelling and diving destination. Water depth ranges from less than 0.3 m on the intertidal reefs to less than 3 m on the sand or seagrass-covered bottom. The area has a diverse array of benthic marine habitat. During a marine survey of the area, over 200 flora and fauna species were positively identified, with many more remaining unidentified due to the diversity of species supported in this marine environment. The survey, which was facilitated by direct observations and photographs, …
A Common Pattern Of Somite Cell Rotation In Three Species Of Pipidae, Shou-Yuan Fan, Rafael O. De Sá, Gary P. Radice
A Common Pattern Of Somite Cell Rotation In Three Species Of Pipidae, Shou-Yuan Fan, Rafael O. De Sá, Gary P. Radice
Biology Faculty Publications
During amphibian somitogenesis, presumptive myotome cells change shape from round or polygonal to elongated and aligned parallel to the notochord (for reviews see Radice, et al., 1989; Keller, 2000). Although the final orientation of myotomal cells is always axial, the movements that achieve this final arrangement can differ greatly between species. The simplest movement is that seen in Bombina variegata, Pelobates fuscus, and Bufo bufo (Brustis et al., 1976; Brustis, 1979; Kielbowna, 1981 ). In these anurans, after segmentation myotomal cells simply elongate along the embryo’s anteroposterior axis. The urodeles Ambystoma mexicanum and Pleurodeles waltl have a very different pattern; …
