Taxonomic Review Of The Wingmite Genus Cameronieta (Acari: Spinturnicidae) On Neotropical Bats, With A New Species From Northeastern Brazil, Juliana C. Almeida, Donald D. Gettinger, Scott Lyell Gardner

Scott L. Gardner Publications

The ectoparasitic mite genus Cameronieta (Acari: Mesostigmata: Spinturnicidae) is endemic to the New World and associated exclusively with bats of the family Mormoopidae. The genus consists of 7 species, 4 broadly distributed through the Caribbean and mainland of North and South America, and 3 species limited to the Greater Antilles archipelago. We present a brief review of the taxonomic history, redefine the genus, and consider some questions that remain concerning the biology and systematics of the group. A new species, Cameronieta almaensis n. sp., is described from the wings of Pteronotus parnellii collected from the Serra das Almas Reserve, in …

Phylogeny And Biogeography Of Species Of Syphacia Seurat, 1916 (Nemata : Oxyurida : Oxyuridae) From The Australian Bioregion, Haylee J. Weaver, Scott Monks, Scott Gardner

Scott L. Gardner Publications

Pinworm nematodes of the genus Syphacia (Nemata : Oxyurida : Oxyuridae) have a global distribution, and infect the caecum of rodents. Within the Australian Bioregion, 17 species of Syphacia infect a range of rodent hosts. Pinworms are traditionally thought to have coevolutionary relationships with their hosts, but the evolution and dispersal of Australian rodents and their helminths remains unclear. This combination of factors allowed us to investigate the likely relationships of Australian Syphacia species based on phylogenetic analysis, overlaid with the ecology and relationships of host species. We conducted a phylogenetic analysis using morphological characters of the species of Syphacia …

Fidelity And Survival Of Breeding Mallards In The Nebraska Sandhills, Zachary J. Cunningham, Larkin Powell, Mark P. Vrtiska

The Prairie Naturalist

Assessment of demographic parameters of a population allows managers to better understand factors affecting populations and increase efficiency of conservation efforts. Few data on demographics exist for mallards (Anas platyrhynchos) breeding in the Nebraska Sandhills. Thus, we used banding data to estimate probabilities of fidelity, survival, band recovery, and recapture of mallards banded in the eastern Sandhills, 2005–2008. Our recapture probability estimate for mallards was 0.074 (95% CI: 0.033–0.158), and the recovery probability estimate was 0.300 (95% CI: 0.156–0.497). Mallard annual survival was 0.795 (95% CI: 0.609–0.906) with a fidelity probability of 0.618 (95% CI: 0.283–0.868). High annual …

Differential Wolf-Pack-Size Persistence And The Role Of Risk When Hunting Dangerous Prey, Shannon M. Barber-Meyer, L. David Mech, Wesley E. Newton, Bridget L. Borg

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

Risk to predators hunting dangerous prey is an emerging area of research and could account for possible persistent differences in gray wolf (Canis lupus) pack sizes. We documented significant differences in long-term wolf-pack-size averages and variation in the Superior National Forest (SNF), Denali National Park and Preserve, Yellowstone National Park, and Yukon, Canada (p < 0.01). The SNF differences could be related to the wolves’ risk when hunting primary prey, for those packs (N = 3) hunting moose (Alces americanus) were significantly larger than those (N = 10) hunting white-tailed deer (Odocoileus virginianus) (F_1,8 = 16.50, p = 0.004). Our data support the hypothesis that differential pack-size persistence may be …

Success Stories And Emerging Themes In Conservation Physiology, Christine L. Madliger, Steven J. Cooke, Erica J. Crespi, Jennifer L. Funk, Kevin R. Hultine, Kathleen E. Hunt, Jason R. Rohr, Brent J. Sinclair, Cory D. Suski, Craig K. R. Willis, Oliver P. Love

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

The potential benefits of physiology for conservation are well established and include greater specificity of management techniques, determination of cause–effect relationships, increased sensitivity of health and disturbance monitoring and greater capacity for predicting future change. While descriptions of the specific avenues in which conservation and physiology can be integrated are readily available and important to the continuing expansion of the discipline of ‘conservation physiology’, to date there has been no assessment of how the field has specifically contributed to conservation success. However, the goal of conservation physiology is to foster conservation solutions and it is therefore important to assess whether …

Determining The Barriers To And Opportunities For Community Involvement In The Management Of The Nanda Devi Biosphere Reserve, Uttarakhand, India, Trisha Singh

Graduate Student Theses, Dissertations, & Professional Papers

Today’s global political environment places a high value on social equality and economic well- being. In this climate, emphasizing biodiversity conservation over socio-economic development through exclusionary methods of habitat protection has become ethically questioned and politically dangerous. The goal of this research was to understand the barriers and opportunities for local involvement in the management of the Nanda Devi Biosphere Reserve in Uttarakhand, India. We attempted to understand the feasibility of local community involvement in the management of the NDBR from the perspective of policy-making organizations and that of the local communities.

Key findings highlight barriers to community participation at …

Predicting The Impact Of Future Climate On Ecologically Important Macroalgae, Charlie Phelps

Theses: Doctorates and Masters

Macroalgae play an important role in coastal reef systems and are often referred to as ecosystem engineers. They serve as primary producers, supporting a diverse range of organisms, and are a sink for atmospheric CO2. Water acidification and ocean warming caused by anthropogenic activities are affecting many marine flora and fauna, potentially impacting the physical and chemical performance of macroalgae and the consumption rates of associated herbivores. Many studies have focused on ocean acidification or ocean warming individually but there is an overall lack of research investigating the combined effects and the ensuing repercussions on consumer-prey relationships.

Identifying Plant Functional Traits To Assist Ecological Intervention In A Drying Landscape, Ana Luiza Muler

Theses: Doctorates and Masters

Mediterranean-type ecosystems (MTEs) are among the most vulnerable to land use and climate change and many attempts are in place to restore these ecosystems. Therefore, it is necessary to assess differences in plants’ ability to withstand water-stress, including biotic interactions. Such knowledge helps us understand community assembly, which is crucial for ecological intervention. This study involved: (1) reviewing the literature on traits that can differentiate functional types; (2) adapting the methodology to measure leaf water potential at turgor loss point (πtlp) for small-leaved species; (3) using these traits to quickly identify water-use strategies of adult …

Premise of the study: Low-elevation surveys with small aerial drones (micro–unmanned aerial vehicles [UAVs]) may be used for a wide variety of applications in plant ecology, including mapping vegetation over small- to medium-sized regions. We provide an overview of methods and procedures for conducting surveys and illustrate some of these applications.

Methods: Aerial images were obtained by flying a small drone along transects over the area of interest. Images were used to create a composite image (orthomosaic) and a digital surface model (DSM). Vegetation classification was conducted manually and using an automated routine. Coverage of an individual species …

Baseline Study Of Recovering Headwater Streams In The Sapphire Mountains, Western Montana, Morgan Vinyard

Graduate Student Theses, Dissertations, & Professional Papers

Many riparian areas in the western United States have been degraded by grazing and logging. In the year 2000, the Montana Department of Environmental Quality (DEQ) re-initiated an effort to identify and characterize reference streams, or least impacted streams in each region of the state. In Montana’s Bitterroot Valley, most streams have been impacted by grazing, irrigation, and timber production. The Montana DEQ has not been able to identify reference streams in the Sapphire Mountains on the east side of this valley. MPG Ranch, located on the west-facing slopes of the Sapphire Mountains and purchased in 2009 by a conservation-minded …

Conservation Genetics On The Frontline, Kenneth W. Rand

Graduate Student Theses, Dissertations, & Professional Papers

Conservation genetics stands out as an effective tool for discovering and monitoring rare, endangered or invasive populations of plants and animals. Particularly when compared to traditional search and capture methods, it provides more holistic studies to preserve the disappearing biodiversity of the American West and the world.

Three stories highlight the work done to preserve biodiversity through the use of conservation genetics:

1. Trout Rescue: A new hope for westslope cutthroat in Montana How to save a disappearing westslope cutthroat trout through genetic rescue by adding genetic diversity to ensuring future survival in increasingly warming waters more harm than good. …

Spatio-Temporal Analysis Of Ungulate Browsing On Willow (Salix Spp.) Communities Within The Northern Range Of Yellowstone, Donald L. Belile Jr.

Graduate Student Theses, Dissertations, & Professional Papers

Variation in ungulate browsing intensity on willow (Salix spp.) communities across Yellowstone’s northern range has been attributed to various biophysical factors including climate, topography, and predators. These studies were conducted without a long-term browsing dataset; they lacked a spatially extensive sampling design, and did not include dynamic snow characteristics known to affect ungulate mobility, habitat selection, and foraging strategies. We therefore focused on snow, an extreme landscape level disturbance that places nutritional stress on ungulates during the winter when most browsing on shrubs occurs. We applied a non-destructive sampling method by consecutively recording whether stem leaders were browsed between …

The Interrelationships Of Placental Mammals And The Limits Of Phylogenetic Inference, James E. Tarver, Mario Dos Reis, Siavash Mirarab, Raymond J. J. Moran, Sean Parker, Joseph E. O'Reilly, Benjamin L. King, Mary J. O'Connell, Robert J. Asher, Tandy Warnow, Kevin J. Peterson, Philip C.J. Donoghue, Davide Pisani

Dartmouth Scholarship

Placental mammals comprise three principal clades: Afrotheria (e.g., elephants and tenrecs), Xenarthra (e.g., armadillos and sloths), and Boreoeutheria (all other placental mammals), the relationships among which are the subject of controversy and a touchstone for debate on the limits of phylogenetic inference. Previous analyses have found support for all three hypotheses, leading some to conclude that this phylogenetic problem might be impossible to resolve due to the compounded effects of incomplete lineage sorting (ILS) and a rapid radiation. Here we show, using a genome scale nucleotide data set, microRNAs, and the reanalysis of the three largest previously published amino acid …

Vestigial Serrula In Scorpion Genera Paravaejovis, , Smeringurus And Vejovoidus (Scorpiones: Vaejovidae), Victor Fet, Michael E. Soleglad, Michael S. Brewer, David P. A. Neff, Michael L. Norton

Euscorpius

The presence of vestigial serrula on the ventral edge of the cheliceral movable finger is established for vaejovid genera Paravaejovis, Paruroctonus, Smeringurus, and Vejovoidus. Detailed descriptions and SEM images illustrating the various manifestations of this interesting cheliceral structure are provided for many species of these four genera. A brief systematic overview of this structure as it exists in Recent scorpions is also presented.

Serrula In Retrospect: A Historical Look At Scorpion Literature (Scorpiones: Orthosterni), Matthew R. Graham, Victor Fet

Euscorpius

Serrula, a small comb-like structure on the ventral aspect of cheliceral movable finger in scorpions, has often been overlooked or ignored. Scorpion genera that are currently known to possess serrula belong to six families: Chactidae, Euscorpiidae, Iuridae, Pseudochactidae, Superstitioniidae, and Vaejovidae. All relevant literature on scorpion serrula is reviewed, and serrula of representative scorpion taxa is illustrated by SEM images. We suggest that the inconsistency in reporting serrula is based on several factors (or combination thereof): (a) serrula tines can quite often be broken off partially or completely, especially in adults; (b) serrula can be vestigial and hardly visible under …

On The Poorly Known Genus Mesotityus González-Sponga, 1981 (Scorpiones: Buthidae), Luis F. De Armas, Fernando J. M. Rojas-Runjaic

Euscorpius

Examination of new available material (18 females and six males) of the rare Venezuelan scorpion Mesotityus vondangeli González-Sponga, 1981 (Buthidae) demonstrated that there are consistent taxonomic characters to consider it as a genus different from Tityus C. L. Koch, 1836 sensu stricto. Nevertheless, it shares important characters with species of the Tityus clathratus group (=subgenus Archaeotityus Lourenço, 2006). An emended diagnosis of Mesotityus is given, as well as data on natural history, meristic and morphometric variation.

Taxonomic Position Of The Genus Sassanidotus Farzanpay, 1987 (Scorpiones: Buthidae), František Kovařík, Victor Fet

Euscorpius

Sassanidotus Farzanpay, 1987 is a valid genus closely related to Compsobuthus Vachon, 1949, with which it shares most characters including the shape of carinae on the carapace and mesosoma. The main difference is that Sassanidotus has only three granules located proximally to the terminal granule on the movable finger of pedipalp, whereas Compsobuthus and also Mesobuthus Vachon, 1950 have four such granules. Sassanidotus Farzanpay, 1987 includes two species, Sassanidotus zarudnyi (Birula, 1900) (type species) from Iran and Sassanidotus gracilis thus zarudnyi sarghadensis Birula, 1903, syn. n.) from Afghanistan, Iran, and Pakistan. The neotype is designated for S. zarudnyi.

Mechanisms Of Adaptation In The Newly Invasive Species Brachypodium Sylvaticum (Hudson) Beauv., Gina Lola Marchini

Dissertations and Theses

It is common knowledge that invasive species cause worldwide ecological and economic damage, and are nearly impossible to eradicate. However, upon introduction to a novel environment, alien species should be the underdogs: They are present in small numbers, possess low genetic diversity, and have not adapted to the climate and competitors present in the new habitat. So, how are alien species able to invade an environment occupied by native species that have already adapted to the local environment? To discover some answers to this apparent paradox I conducted four ecological genetic studies that utilized the invasive species Brachypodium sylvaticum (Hudson) …

Redescription And Lectotype Designation Of Vaejovis Lapidicola Stahnke, 1940 (Scorpiones: Vaejovidae), Matthew R. Graham

Euscorpius

The original description of the Arizona scorpion species Vaejovis lapidicola Stahnke, 1940 consists of a single paragraph. Furthermore, a holotype for this species was never designated. To remedy this, two syntypes of V. lapidicola were obtained for study. A male syntype is redescribed and designated the lectotype, and a female is assigned as a paralectotype. The taxonomic status of V. lapidicola is also confirmed.

Laterobasal Aculear Serrations (Las) In Scorpion Family Vaejovidae (Scorpiones: Chactoidea), Victor Fet, Michael E. Soleglad, Michael S. Brewer

Euscorpius

The discovery of a new structure on the laterobasal aspect of the telson aculeus is described here for the first time. This structure, termed the laterobasal aculear serrations (LAS), is a row of minute denticles located on each side of the aculeus base, found exclusively in scorpion family Vaejovidae, thus potentially providing a new synapomorphy for this New World family. The LAS structure of major representative vaejovid genera and Vaejovis groups is illustrated with SEM micrographs. Also provided is a comprehensive list of non-vaejovid Recent scorpion genera examined where the LAS structure was found to be absent.

The Effect Of Insularity On The Seasonal Population Structure Of Mesobuthus Gibbosus (Scorpiones: Buthidae), Dimitris Kaltsas, Iasmi Stathi, Moysis Mylonas

Euscorpius

We compared the population structure of Mesobuthus gibbosus from autumn to mid-summer at two similar phryganic ecosystems, one in continental Greece (Thessalia, near Volos city) and one in insular Greece (eastern Crete). Data were collected monthly using the capture-recapture method. At both sites, density was low during the cold period and increased towards summer. During the samplings, only a small percentage of each population was present. Population density and co-occurrence of scorpions with scorpions or other animals was higher in Crete than in Volos, probably due to the higher inter- and intraspecific competition in Volos. The population structure of the …

Duplication Of Pedipalp Segments In The Scorpion Androctonus Crassicauda (Olivier, 1807), Ayşegül Karataş, Mustafa Kürtüllü

Euscorpius

An unusual duplication of pedipalp segments is reported from the buthid scorpion Androctonus crassicauda. While the right pedipalp is normal, the anomaly described here occurred on the left pedipalp. This abnormally developed pedipalp included nine segments instead of normal six. It has two trochanters, two femurs and two patellae; the segments are arranged in the following order: coxa, trochanter I, femur I, patella I, trochanter II, femur II, patella II, chela hand, and movable finger. Morphometric measurements, photographs, and general features of the specimen are given.

Constellation Array In Scorpion Genera Paruroctonus, Smeringurus, Vejovoidus, And Paravaejovis (Scorpiones: Vaejovidae), Victor Fet, Michael E. Soleglad, Michael Brewer, David P. A. Neff, Michael L. Norton

Euscorpius

The constellation array (a recently discovered sensory structure on the fixed finger of pedipalp; Fet et al., 2006) is analyzed for a large set of species belonging to four genera in the family Vaejovidae: Paruroctonus, Smeringurus, Vejovoidus, and Paravaejovis. It is shown that this structure is an important taxonomic character. Two distinct configurations are identified, a two-sensilla array for Paruroctonus + Smeringurus + Vejovoidus and a three-sensilla array for genus Paravejovis, both differing from other vaejovid configurations so far investigated. The topology of these two array configurations are analyzed using landmark setae identified in this study.

The Status Of Fishes In The Missouri River, Nebraska: Selected Ancient Fishes, Kirk D. Steffensen

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Several ancient fish species have inhabited the Missouri River and its tributaries for thousands of years prior to major mainstem modifications and fragmentation. However post-anthropogenic modifications, populations of these ancient fish species have been highly diminished. Therefore, the objective of this study was to use historic and current ichthyological records to determine the past and present status for Chestnut Lamprey Ichthyomyzon castaneus, Silver Lamprey Ichthyomyzon unicuspis, Bowfin Amia calva, American Eel Anguilla rostrata, and Burbot Lota lota. Currently, these species are rarely captured and perhaps extirpated from Nebraska waters.

Ability Of Skin Bacteria On The Panamanian Frog Species, Craugastor Fitzingeri, To Inhibit The Fungal Pathogen Batrachochytrium Dendrobatidis, Tiffany N. Bridges

Senior Honors Projects, 2010-2019

An emerging infectious disease caused by the fungus Batrachochytrium dendrobatidis (Bd) is leading to global amphibian declines and is threatening the biodiversity of amphibians. Bd susceptibility varies among individuals, species, and populations perhaps due to defensive mechanisms such as symbiotic skin microbes. Some species of amphibians such as Craugastor fitzingeri, a terrestrial frog native to Central America, continue to persist in Bd-positive environments in Panama. My study focused on identifying antifungal bacterial isolates and determining the culturability of the bacterial community on 15 individuals of C. fitzingeri. Morphologically distinct isolates were challenged against Bd in …
