Ecology and Evolutionary Biology Publications and Other Works
Phylogeographic data indicate that DNA differences consistently exist between the North American and European allopatric populations of Gymnopus confluens. Conversely, pairing experiments show that collections from both populations were sexually compatible in vitro and detailed morphological examinations of numerous fresh and dried basidiomata do not produce qualitative differences. Percent ITS sequence divergence between Europe and North American collections of G. confluens was 3.25%. Species delineation metrics including Rosenberg’s PAB statistic, PID metrics, RRD ( randomly distributed) and PTP (Poisson Tree Processes ) gave mixed indications that North American and European populations were distinct at species rank. The ...

Who Invented The Mule Deer (Odocoileus Hemionus)? On The Authorship Of The Fraudulent 1812 Journal Of Charles Le Raye, Neal Woodman
The captivity journal of Charles Le Raye was first published in 1812 as a chapter in A topographical description of the state of Ohio, Indiana Territory, and Louisiana, a volume authored anonymously by “a late officer in the U. S. Army”. Le Raye was purported to be a French Canadian fur trader who, as a captive of the Sioux, had travelled across broad portions of the Missouri and Yellowstone river drainages a few years before the Lewis and Clark expedition (1804–1806), and his account of the land, its people, and its natural resources was relied upon as a primary ...
New Records Of Merriam’S Shrew (Sorex Merriami) From Western North Dakota, 2015 Northeastern State University, OK
New Records Of Merriam’S Shrew (Sorex Merriami) From Western North Dakota, Michael J. Shaughnessy Jr., Neal Woodman
Despite having a broad geographic distribution, Merriam’s Shrew (Sorex merriami Dobson 1890) is known from a relatively few, widely-scattered localities. In North Dakota, the species was known from only a single poorly-preserved specimen collected in 1913 near Medora. We recently collected two new specimens of Merriam’s Shrew from Billings and McKenzie counties in the western quarter of the state. These specimens confirm the presence of S. merriami in North Dakota and better define the northeastern edge of the species’ distribution.

Evaluation Of Biochar As Fertilizer For The Growth Of Some Seasonal Vegetables, 2015 Institute of Natural and Management Sciences, Rawalpindi and Bioresource Research Centre, Islamabad
Evaluation Of Biochar As Fertilizer For The Growth Of Some Seasonal Vegetables, Kainaat William, Rizwana Aleem Qureshi
Journal of Bioresource Management
Biochar was used to replace inorganic fertilizers. Biochar was synthesized by the process of pyrolysis using horse dung (5kg) and dry grass (25kg) to check its effect on the growth of some local vegetables i.e. okra, beans, coriander and mint. These plants were kept in three different environments i.e. outdoor, indoor and greenhouse conditions. In each condition three replications were made for each plant and biochar was applied on them. Control plants (without biochar) were also grown in each condition. Parameters studied were pH, water holding capacity, ammonia, nitrates, chlorophyll content, fertility analysis, temperature and humidity, number of ...

Cuban Treefrogs, Osteopilus Septentrionalis (Duméril & Bibron 1841) (Anura: Hylidae), And Other Nonindigenous Herpetofauna Interdicted In Grenada, Lesser Antilles., Louis A. Somma, Paul R. Graham
Papers in Herpetology
The number of introduced nonindigenous species of amphibians and reptiles within the greater Caribbean, including Grenada, is escalating and has become an ever-increasing critical conservation concern (Daudin and de Silva 2011; Powell et al. 2011; Powell and Henderson 2012). The amount of development, tourism, and consequent import commerce is increasing, requiring careful regulation of the pet trade and fauna introduced for biological control as well as diligence in cargo inspection. Herein we document the first records of nonindigenous Cuban Treefrogs, Osteopilus septentrionalis (Duméril and Bibron 1841), interdicted from cargo, along with recent interceptions of two species of nonindigenous lizards already ...

An Individual-Based Model For Feral Hogs In Great Smoky Mountains National Park, 2015 Appalachian State University
An Individual-Based Model For Feral Hogs In Great Smoky Mountains National Park, Rene A. Salinas, William H. Stiver, Joseph L. Corn, Suzanne Lenhart, Charles Colin, Marguerite Madden, Kurt C. Vercauteren, Brandon B. Schmit, Ellen Kasari, Agricola Odoi, Graham Hickling, Hamish Mccallum
The expansion of feral hog (Sus scrofa)populations in the United States has resulted in increased efforts to develop and implement control strategies designed to minimize the impacts done by this invasive species. We describe an individual-based model for feral hogs in Great Smoky Moun- tains National Park (GSMNP). The objectives of the model are to provide an understanding of the population dynamics of this feral hog population and to determine the efficacy of the annual harvest as a population control method. Results suggest that the dynamics of the population are driven by fall hard mast production and the GSMNP ...
On The Analysis Of Phylogenetically Paired Designs, 2015 Chapman University
On The Analysis Of Phylogenetically Paired Designs, Jennifer L. Funk, Cyril Rakovski, J. Michael Macpherson
Biology, Chemistry, Earth, and Environmental Sciences Faculty Articles and Research
As phylogenetically controlled experimental designs become increasingly common in ecology, the need arises for a standardized statistical treatment of these datasets. Phylogenetically paired designs circumvent the need for resolved phylogenies and have been used to compare species groups, particularly in the areas of invasion biology and adaptation. Despite the widespread use of this approach, the statistical analysis of paired designs has not been critically evaluated. We propose a mixed model approach that includes random effects for pair and species. These random effects introduce a “two-layer” compound symmetry variance structure that captures both the correlations between observations on related species within ...

The most frequently encountered species includes Gambusia holbrooki, Percina nigrofasciata, Esox americanus, Notropis texanus, Lepomis macrochirus, Cyprinella n. sp. cf venusta, Notropis ...
An Assessment Of South China Tiger Reintroduction Potential In Hupingshan And Houhe National Nature Reserves, China, Yiyuan Qin, Philip J. Nyhus, Courtney L. Larson, Charles J.W. Carroll, Jeff Muntifering, Thomas D. Dahmer, Lu Jun, Ronald L. Tilson
Philip J. Nyhus
Human-caused biodiversity loss is a global problem, large carnivores are particularly threatened, and the tiger (Panthera tigris) is among the world’s most endangered large carnivores. The South China tiger (Panthera tigris amoyensis) is the most critically endangered tiger subspecies and is considered functionally extinct in the wild. The government of China has expressed its intent to reintroduce a small population of South China tigers into a portion of their historic range as part of a larger goal to recover wild tiger populations in China. This would be the world’s first major tiger reintroduction program. A free-ranging population of ...
Optimizing Conservation Strategies For Mexican Free-Tailed Bats: A Population Viability And Ecosystem Services Approach, Ruscena Wiederholt, Laura López-Hoffman, Colleen Svancara, Gary Mccracken, Wayne Thogmartin, Jay E. Diffendorfer, Brady Mattson, Kenneth Bagstad, Paul Cryan, Amy L. Russell, Darius Semmens, Rodrigo A. Medellín

Conservation planning can be challenging due to the need to balance biological concerns about population viability with social concerns about the benefits biodiversity provide to society, often while operating under a limited budget. Methods and tools that help prioritize conservation actions are critical for the management of at-risk species. Here, we use a multi-attribute utility function to assess the optimal maternity roosts to conserve for maintaining the population viability and the ecosystem services of a single species, the Mexican free-tailed bat (Tadarida brasiliensis mexicana). Mexican free-tailed bats provide ecosystem services such as insect pest-suppression in agricultural areas and recreational viewing ...
Variation In The Myosoricine Hand Skeleton And Its Implications For Locomotory Behavior (Eulipotyphla: Soricidae), Neal Woodman, Frank A. Stabile
Substrate use and locomotory behavior of mammals are typically reflected in external characteristics of the forefeet, such as the relative proportions of the digits and claws. Although skeletal anatomy of the forefeet can be more informative than external characters, skeletons remain rare in systematic collections. This is particularly true for the Myosoricinae (Eulipotyphla: Soricidae), a small clade of African shrews that includes both ambulatory forest shrews (Myosorex) and semifossorial mole shrews (Surdisorex). Most species in this subfamily have restricted distributions, and their behavior and ecology are mostly unstudied. To better understand the potential range of locomotory behavior among myosoricines, we ...
Efficacy Of Dormant Season Herbicide Application On Control Of Japanese Honeysuckle (Lonicera Japonica) For Habitat Restoration In Kentucky, Jason L. Weese
Theses and Dissertations--Forestry
Kentucky’s disappearing native grassland communities provide habitat for native flora and fauna. A study was conducted to compare the efficacy of herbicides in control of the invasive Japanese honeysuckle (Lonicera japonica) applied at times when most native species are dormant. Six herbicide mixtures (glyphosate, glyphosate + imazapyr, glyphosate + imazapic, imazapyr, triclopyr + difluphenzopyr, and metsulfuron + difluphenzopyr) were applied in three seasons to assess the effect of application timing of each mixture on honeysuckle control. Herbicides were applied with a CO2 pressurized sprayer at three sites in a randomized complete block design. Pretreatment sampling indicated that Japanese honeysuckle constituted over 70 ...
Relative Abundances Of The Recently Introduced Barnacles, Megabalanus Coccopoma And An Unidentified Species Of Megabalanus, In The Southeastern U.S., Jennifer L. Tyson
University Honors Program Theses
Megabalanus coccopoma is a prominent invasive species off the coast of Georgia. Recently, among collected samples thought to be M. coccopoma, several individuals of an unidentified species of barnacle were found. The species has been identified as a Megabalanus species, but is still unidentified to the species level. Species identification is difficult due to morphological variation, inconsistent taxonomic keys, and unknown origin. In this study I developed a method to accurately distinguish M. coccopoma from the unidentified Megabalanus sp. using sequence differences in the mitochondrial Cytochrome Oxidase I (COI) gene. This study will provide an accurate estimate of the ...
