Restoration Of Bison (Bison Bison) To Agate Fossil Beds National Monument, A Feasibility Study, Daniel S. Licht Nov 2014

Restoration Of Bison (Bison Bison) To Agate Fossil Beds National Monument, A Feasibility Study, Daniel S. Licht

United States National Park Service: Publications

Executive Summary

Agate Fossil Beds National Monument is a 3,057-acre park located in western Nebraska. The unit is comprised of northern mixed-grass prairie vegetation, typical of the Northern Great Plains. Weather, fire, and grazing are generally considered to be the ecological drivers of prairie ecosystems and critical for prairie health. However, grazing has essentially been absent since the 1960s. In 2014, a Department of the Interior report explicitly listed the park as a high priority for bison restoration. This report evaluates the feasibility, management options, benefits, and challenges of restoring bison to Agate Fossil Beds National Monument.

Natural Infections Of Tetrathyridia Of Mesocestoides Species In Deer Mice, Peromyscus Maniculatus, From New Mexico, John E. Ubelaker, Nora Abdullah, Aya Mouhaffel, Rashmi Ananadampillair, Caitlyn Emigh, Scott Lyell Gardner Sep 2014

Natural Infections Of Tetrathyridia Of Mesocestoides Species In Deer Mice, Peromyscus Maniculatus, From New Mexico, John E. Ubelaker, Nora Abdullah, Aya Mouhaffel, Rashmi Ananadampillair, Caitlyn Emigh, Scott Lyell Gardner

Papers in Parasitology

At Southern Methodist University campus about 6 miles south of Taos, New Mexico, we recovered tetrathyridia of Mesocestoides in five Peromyscus maniculatus in the summers of 2008 (3 of 129, 0.023%), 2009 (0 of 98, 0%), 2010 (1 of 112, 0.008%), 2011 (0 of 88, 0%), and 2012 (1 of 86, 0.011%). Tetrathyridia from the body cavity of one of the five infected mice were injected into the peritoneal cavity of laboratory white mice, Mus musculus. Our later examination of the laboratory mice revealed heavy infections of tetrathyridia continuing to reproduce asexually. Here we provide important new information on …

Background: Domestic cats enjoy an extensive veterinary medical surveillance which has described nearly 250 genetic diseases analogous to human disorders. Feline infectious agents offer powerful natural models of deadly human diseases, which include feline immunodeficiency virus, feline sarcoma virus and feline leukemia virus. A rich veterinary literature of feline disease pathogenesis and the demonstration of a highly conserved ancestral mammal genome organization make the cat genome annotation a highly informative resource that facilitates multifaceted research endeavors.

Findings: Here we report a preliminary annotation of the whole genome sequence of Cinnamon, a domestic cat living in Columbia (MO, USA), …


The Dynamic Proliferation Of Cansines Mirrors The Complex Evolution Of Feliforms, Kathryn B. Walters-Conte, Diana L. E. Johnson, Warren E. Johnson, Stephen J. O'Brien, Jill Pecon-Slattery Jun 2014

The Dynamic Proliferation Of Cansines Mirrors The Complex Evolution Of Feliforms, Kathryn B. Walters-Conte, Diana L. E. Johnson, Warren E. Johnson, Stephen J. O'Brien, Jill Pecon-Slattery

Biology Faculty Articles

Background: Repetitive short interspersed elements (SINEs) are retrotransposons ubiquitous in mammalian genomes and are highly informative markers to identify species and phylogenetic associations. Of these, SINEs unique to the order Carnivora (CanSINEs) yield novel insights on genome evolution in domestic dogs and cats, but less is known about their role in related carnivores. In particular, genome-wide assessment of CanSINE evolution has yet to be completed across the Feliformia (cat-like) suborder of Carnivora. Within Feliformia, the cat family Felidae is composed of 37 species and numerous subspecies organized into eight monophyletic lineages that likely arose 10 million years ago. Using …


New Species Of Ctenomys Blainville 1826 (Rodentia: Ctenomyidae) From The Lowlands And Central Valleys Of Bolivia, Scott Lyell Gardner, Jorge Salazar-Bravo, Joseph A. Cook Jun 2014

New Species Of Ctenomys Blainville 1826 (Rodentia: Ctenomyidae) From The Lowlands And Central Valleys Of Bolivia, Scott Lyell Gardner, Jorge Salazar-Bravo, Joseph A. Cook

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

The genus Ctenomys Blainville 1826 is one of the most diverse of South American hystricognath rodents. Currently, nine species of tuco-tucos are reported from Bolivia, four at elevations above 2,000 m and five inhabiting the lowlands (< 1,000 m). In the present paper, morphology, karyology, and phylogenetic analyses of DNA sequences for a mitochondrial locus were used to assess the taxonomic status of specimens of Ctenomys from localities beyond the previously known ranges of these rodents in the departments of Chuquisaca, Cochabamba, Santa Cruz, and Tarija. Based on these analyses, we describe four new species in the genus Ctenomys, all apparently endemic to the country. In addition, we place Ctenomys goodfellowi Thomas 1921 in synonymy under C. boliviensis Waterhouse 1848 and confirm the presence of C. nattereri …


Coral-Fish Dynamics And Interactions: A Case Study Of Grand Cayman, Eileen Shea Davis Jun 2014

Coral-Fish Dynamics And Interactions: A Case Study Of Grand Cayman, Eileen Shea Davis

Lawrence University Honors Projects

To better understand the ecological interactions of coral reefs, it is important to understand the mechanisms that control the distribution and abundance of reef-building corals as well as the mechanisms that control the diversity and abundance of the fish community that inhabits these reef habitats. The purpose of this study was to identify specific coral-fish interactions among the reefs of Grand Cayman in order to gain insight into the biological effects of fish on the assemblage of hard corals. Using data collected by the Lawrence University Marine Program (LUMP), a number of exploratory statistical analyses were run in order to …

Provided are some general management recommendations regarding Western Massasaugas. Conservation practitioners will need to use professional judgment to make specific management decisions based on objectives, location, and a multitude of variables. This resource was designed to share available knowledge of this at-risk species that will aid in the decision-making process or …


Level Of Uv-B Radiation Influences The Effects Of Glyphosate-Based Herbicide On Fitness Of The Spotted Salamander, Nicholas A. Levis May 2014

Level Of Uv-B Radiation Influences The Effects Of Glyphosate-Based Herbicide On Fitness Of The Spotted Salamander, Nicholas A. Levis

Masters Theses & Specialist Projects

Numerous causes have been implicated in contributing to amphibian population declines since the 1980's, with habitat modification, ultraviolet radiation (UV-B) and environmental contaminants (such as glyphosate-based herbicide) being among the most common. This study identifies the effects of a generic glyphosate-based herbicide (GLY- 4 Plus) on mortality, immune function, body condition, and morphological plasticity of larvae of the spotted salamander (Ambystoma maculatum) under conditions that reflect open and closed canopy light regimes. Larval salamander responses to glyphosate-based herbicide varied depending on UV-B conditions. In general, it appears that an open canopy (i.e. greater UV-B exposure) may confer fitness benefits. In …

Abstract

Plagioscion squamosissimus (Heckel 1840), a fish endemic to the Amazon Basin and commonly known as the “silver croaker”, plays an important role in the ecology and economy of Pará State, Brazil. Knowledge of host-parasite relationships is important to understanding the role of parasites in the control of natural host populations. This work describes histopathological aspects caused by several common intestinal parasites found during a helminthological survey of fish in northern Brazil. We observed a high prevalence of helminth infection, especially by J3 nematode juveniles of the family Anisakidae and metacestodes of the family Protocephalidae (both with 100% prevalence). An …

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

From 1989 through 1998, a total of 358 grasshopper mice were collected and examined for helminth and protistan parasites from several habitat types on the Sevilleta Long Term Ecological Research (LTER) site in New Mexico, U.S.A. Of these, 205 individuals were identified as Onychomys leucogaster (Wied-Neuwied 1841) and 153 individuals were classified as O. arenicola Mearns 1896. Many individuals of Onychomys were infected with a new species of Hymenolepididae (Hymenolepis robertrauschi), which is herein described, illustrated, and compared with all species of Nearctic Hymenolepis s. str. Hymenolepis robertrauschi was found in 26% of the individuals of O. arenicola …

Averting Lemur Extinctions Amid Madagascar's Political Crisis, Christoph Schwitzer, Russell Mittermeier, Steig Johnson, Giuseppe Donati, Mitchell Irwin, Heather Peacock, Jonah Ratsimbazafy, Josia Razafindramanana, Edward E. Louis, Lounes Chikhi, Ian C. Colquhoun, Jennifer Tinsman, Ranier Dolch, Marni Lafleur, Stephen Nash, Erik Patel, Blanchard Randrianambinina, Tove Rasolofoharivelo, Patricia C. Wright

Anthropology Publications

The most threatened mammal group on Earth, Madagascar’s five endemic lemur families (lemurs are found nowhere else), represent more than 20% of the world’s primate species and 30% of family-level diversity. This combination of diversity and uniqueness is unmatched by any other country—remarkable considering that Madagascar is only 1.3 to 2.9% the size of the Neotropics, Africa, or Asia, the other three landmasses where nonhuman primates occur. But lemurs face extinction risks driven by human disturbance of forest habitats. We discuss these challenges and reasons for hope in light of site-specific, local actions proposed in an emergency conservation action plan.

The Longhorn Beetles (Coleoptera: Cerambycidae) Of Nebraska, Usa: New State Records, A Checklist Of Known Species, And Distribution Maps, Stephen M. Spomer

University of Nebraska State Museum: Entomology Papers

One hundred eighty-three species/subspecies of longhorn beetles are recorded from Nebraska, an increase of 19 species since 1971. The greatest number of recent discoveries have come from sites along the Missouri River, especially Indian Cave State Park in southeastern Nebraska, as well as the Pine Ridge at Chadron, Nebraska.


Redescription Of Oligacanthorhynchus Microcephalus (Rudolphi, 1819) Schmidt 1972 (Syn. Oligacanthorhynchus Tortuosa (Leidy, 1850) Schmidt 1972) (Acanthocephala: Oligacanthorhynchidae), Dennis J. Richardson, Scott Lyell Gardner, Jonathan W. Allen Jr. Jan 2014

Redescription Of Oligacanthorhynchus Microcephalus (Rudolphi, 1819) Schmidt 1972 (Syn. Oligacanthorhynchus Tortuosa (Leidy, 1850) Schmidt 1972) (Acanthocephala: Oligacanthorhynchidae), Dennis J. Richardson, Scott Lyell Gardner, Jonathan W. Allen Jr.

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

Oligacanthorhynchus microcephalus (Rudolphi, 1819) Schmidt, 1972 was originally described from the philander opossum Caluromys philander from Brazil. Oligacanthorhynchus tortuosa (Leidy, 1850) Schmidt, 1972 was originally described from the Virginia opossum (Didelphis virginiana) in North America. Six years after describing O. tortuosa, Leidy indicated the synonomy of O. tortuosa with O. microcephalus. This taxonomic view persisted for decades until Van Cleave, in 1924, recognized the validity of O. tortuosa, apparently without examining the type material of O. microcephalus. Subsequent workers have recognized two species of Oligacanthorhynchus from New World opossums: O. microcephalus from South American …

Journal Articles

Aim Global-scale studies are required to identify broad-scale patterns in the distributions of species, to evaluate the processes that determine diversity and to determine how similar or different these patterns and processes are among different groups of freshwater species. Broad-scale patterns of spatial variation in species distribution are central to many fundamental questions in macroecology and conservation biology. We aimed to evaluate how congruent three commonly used metrics of diversity were among taxa for six groups of freshwater species.

Location Global.

Methods We compiled geographical range data on 7083 freshwater species of mammals, amphibians, reptiles, fishes, crabs and crayfish to …


Recognition Of Two New Species Of Freshwater Crabs From The Seychelles Based On Molecular Evidence (Potamoidea: Potamonautidae)., Neil Cumberlidge, Savel Regan Daniels Phd Jan 2014

Recognition Of Two New Species Of Freshwater Crabs From The Seychelles Based On Molecular Evidence (Potamoidea: Potamonautidae)., Neil Cumberlidge, Savel Regan Daniels Phd

Journal Articles

The Afrotropical freshwater crab genus Seychellum is endemic to the granitic Seychelles in the Indian Ocean (Mahé, Silhouette, Praslin, La Digue and Frégate). Here we describe two new cryptic species of Seychellum that represent two evolutionarily separate lineages of a previously monotypic genus. This raises to three the number of species of freshwater crabs known from Seychelles. Each species is endemic to either one island (Silhouette) or to a pair of islands (Mahé and Frégate, or Praslin and La Digue). The three species can be clearly distinguished as separate lineages by DNA analysis, haplotyping and examination of gonopod characters. The …

Varestrongylus Eleguneniensis Sp. N. (Nematoda: Protostrongylidae): A Widespread, Multi-Host Lungworm Of Wild North American Ungulates, With An Emended Diagnosis For The Genus And Explorations Of Biogeography, Guilherme G. Verocai, Susan J. Kutz, Manon Simard, Eric P. Hoberg

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

Background: A putative new species of Varestrongylus has been recently recognized in wild North American ungulates based on the ITS-2 sequences of larvae isolated from feces during a wide geographic survey. No taxonomic description was provided, as adult specimens were not examined. Methods: Lungworm specimens were collected in the terminal bronchioles of muskoxen from Quebec, and a woodland caribou from central Alberta, Canada. The L3 stage was recovered from experimentally infected slugs (Deroceras spp.). Description of specimens was based on comparative morphology and integrated approaches. Molecular identity was determined by PCR and sequencing of the ITS-2 region of …

Verocai, Eric P. Hoberg, Turid Vikøren, Kjell Handeland, Bjørnar Ytrehus, Andrew M. Rezansoff, Rebecca K. Davidson, John S. Gilleard, Susan J. Kutz

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

Background: Varestrongylus alces, a lungworm in Eurasian moose from Europe has been considered a junior synonym of Varestrongylus capreoli, in European roe deer, due to a poorly detailed morphological description and the absence of a type-series.

Methods: Specimens used in the redescription were collected from lesions in the lungs of Eurasian moose, from Vestby, Norway. Specimens were described based on comparative morphology and integrated approaches. Molecular identification was based on PCR, cloning and sequencing of the ITS-2 region of the nuclear ribosomal DNA. Phylogenetic analysis compared V. alces ITS-2 sequences to these of other Varestrongylus species …
