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
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
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
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
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
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
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
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
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
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
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
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 …

Euscorpius
The diagnostic characters originally established by Herbert L. Stahnke (1940a, 1940b, 1974) in his description of genus Serradigitus are studied in detail from several new perspectives. A new genus, Stahnkeus, gen. nov., is described based on the presence of inner accessory (IAD) denticles on the chelal fingers, unprecedented in family Vaejovidae. Five species of Serradigitus are transferred to Stahnkeus: Stahnkeus harbisoni (Williams, 1970), comb. nov. (=Serradigitus harbisoni); Stahnkeus deserticola (Williams, 1970), comb. nov. (=Serradigitus deserticola); Stahnkeus subtilimanus (Soleglad, 1972), comb. nov. (=Serradigitus subtilimanus); Stahnkeus allredi (Sissom et Stockwell, 1991), …

Descriptions and redescriptions are based mainly on the material collected in Tibet Autonomous Region and Yunnan Province. Checklists and identification keys for Chinese species of …
The Systematic Position Of The Scorpion Genera Heteroscorpion Birula, 1903 And Urodacus Peters, 1861 (Scorpiones: Scorpionoidea), Michael E. Soleglad, Victor Fet, František Kovařík
The Systematic Position Of The Scorpion Genera Heteroscorpion Birula, 1903 And Urodacus Peters, 1861 (Scorpiones: Scorpionoidea), Michael E. Soleglad, Victor Fet, František Kovařík
Euscorpius
Stockwell (1989), in an unpublished revision, suggested the elevation of subfamily Urodacinae to the family rank, and considered Heteroscorpioninae a subfamily of Ischnuridae. Heteroscorpioninae was formally elevated to the family rank by Lourenço (1996a), and Urodacinae, by Prendini (2000). As a result of a detailed cladistic analysis, Prendini (2000, 2003b) considered families Heteroscorpionidae and Urodacidae to be sister groups, although an al-ternative topology was available. Soleglad & Fet (2003b) questioned the results of Prendini (2000) but nevertheless retained the monophyly of Heteroscorpion and Urodacus pending more detailed analysis; they recognized two valid monotypic subfamilies, Heteroscorpioninae and Urodacinae, under Urodacidae. Our …

Review Of Tunisian Species Of The Genus Buthus With Descriptions Of Two New Species And A Discussion Of Ehrenberg’S Types (Scorpiones: Buthidae), František Kovařík
Euscorpius
Buthus chambiensis, sp. n. and Buthus dunlopi, sp. n. from Tunisia are described. Presented is also a key to four Tunisian species of the genus Buthus. The males of B. chambiensis, sp. n. and B. paris (C. L. Koch, 1839) have narrower chela than the females, which distinguishes them from B. tunetanus (Herbst, 1800) and B. dunlopi, sp. n. Uniformly yellowish mesosoma and very narrow chela of pedipalps distinguish B. chambiensis, sp. n. from Buthus paris (C. L. Koch, 1839). Morphologically closest to B. chambiensis sp. n. is Buthus barcaeus Birula, 1909, comb. n. …
A New Species Of The Genus Buthus (Scorpiones: Buthidae) From Northern Cameroon, Wilson R. Lourenço, Elise-Anne Leguin
A New Species Of The Genus Buthus (Scorpiones: Buthidae) From Northern Cameroon, Wilson R. Lourenço, Elise-Anne Leguin
Euscorpius
A new species belonging to the genus Buthus Leach (Scorpiones: Buthidae) is described from northern Cameroon in Central Western Africa. The new species can be included in the “Buthus occitanus” complex of species, and probably can be associated with the “Buthus occitanus” from the former French West Africa (AOF) previously reported by Vachon from this large region. This is the first record of a Buthus species from Cameroon, and with the description of Buthus prudenti sp. n., the status of one more population of Buthus spp. from the sub-Saharan region of Africa is clarified.
A Seven-Legged Scorpion: The First Teratological Leg Absence Found In Scorpio Maurus Fuscus (Scorpiones: Scorpionidae), David David
Euscorpius
A teratological leg absence anomaly is reported and discussed in a Scorpio maurus fuscus (Scorpionidae) specimen from Israel. In this scorpion, the third right leg is completely missing, and the fourth right leg has a deformed coxa, which abuts the entire lateral edge of the sternum. The area anterior to the sternum is visibly curved to the right. This is the first leg absence anomaly reported in scorpions.

The Genus Auyantepuia González-Sponga, 1978 Is Confirmed As A Synonym Of Broteochactas Pocock, 1893 (Scorpiones: Chactidae), Michael E. Soleglad, Victor Fet
Euscorpius
The genus Auyantepuia González-Sponga, 1978 is confirmed as a synonym of Broteochactas Pocock, 1893 (Scorpiones: Chactidae). It was correctly synonymized with Broteochactas by Francke & Boos (1986) and listed as such by Soleglad & Fet (2003) but resurrected by Lourenço & Araújo (2004). We reconfirm that the generic name Auyantepuia, based on the type species Broteochactas scorzai Dagert, 1957 from Venezuela, is a synonym of Broteochactas, based on the type species Broteochactas nitidus Pocock, 1893 from Trinidad. All other seven “short-fingered” species from French Guiana and Brazil, classified by Lourenço & Araújo (2004) under Auyantepuia, belong to …

Taxonomic Position Of Species Of The Genus Buthacus Birula, 1908 Described By Ehrenberg And Lourenço, And Description Of A New Species (Scorpiones: Buthidae), František Kovařík
Euscorpius
Lectotypes are designated for Androctonus (Leiurus) leptochelys Ehrenberg, 1829, Androctonus (Leiurus) thebanus Ehrenberg, 1828 and Androctonus (Leiurus) macrocentrus Ehrenberg, 1828. In recent papers the latter two species have been regarded as synonyms of Buthacus leptochelys, however its type series is composed of seven specimens that in reality belong to three species. The type series of Androctonus leptochelys includes specimens belonging to Buthacus leptochelys and Buthacus spatzi (Birula, 1911), and the type series of Androctonus macrocentrus includes specimens belonging to Buthacus leptochelys and Buthacus tadmorensis (Simon, 1892).

A Desert In Disguise: The Resilience Of The Nebraska Sandhills, Jeff Hartman
A Desert In Disguise: The Resilience Of The Nebraska Sandhills, Jeff Hartman
School of Natural Resources: Dissertations, Theses, and Student Research
The Nebraska Sandhills are the largest sand dune system in the Western Hemisphere, and are unique because they remain relatively undisturbed from row crop agriculture. Research in the past two decades demonstrated that the Sandhills are dynamic on millennial timescales, switching between stabilized, vegetated states to non-vegetated, mobilized states. The Sandhills are currently stabilized, but understanding how ecological processes are altered as sand dunes transition from stabilized to mobilized states, provides insight into the thresholds, stability, and resilience of this grassland ecosystem. My research investigated the impacts of vegetation disturbances on ecological processes and the sand dune surface stability. For …
Response Of Fishes To Restoration Projects In Bayou St. John Located Within The City Of New Orleans, Louisiana, Including Hydrological Characterization And Hydrodynamic Modelling, Patrick W. Smith
University of New Orleans Theses and Dissertations
Quantifying the impacts of restoration on coastal waterways is crucial to understanding their effectiveness. Here, I look at the impacts of multiple restoration projects on urban waterways within the city limits of New Orleans, LA, with an emphasis on the response of fishes. First I report the effects of two projects designed to improve exchange down estuary on the hydrologic characteristics of Bayou St. John (BSJ). Within BSJ, flow is dominated by subtidal wind driven processes. Removal of an outdated flood control structure did not appear to alter exchange in BSJ, but removal combined with sector gate openings did. I …

This study quantifies the changes in vegetation composition and structure of a fire-excluded Pinus palustris (longleaf pine) wetland savanna restoration site in southeastern in comparison to a proximate contemporary reference site. The restoration site was invaded by hardwood species and off-site pines, and never underwent extensive soil disturbance. The restoration treatments involved logging across portions of the site and the reintroduction of fire across the entire site. All species present in 10m2 quadrats were recorded prior to treatment and throughout the 17 year study at reference and treatment sites. The community composition of both logged and unlogged sites converged …
