A New Vaejovis From The Mogollon Highlands Of Northern Arizona (Scorpiones: Vaejovidae), Richard F. Ayrey

Euscorpius

A new scorpion species, Vaejovis halli sp. nov., is described. This relatively small, brown new species is found on Mount Ord in the Mazatzal Mountains along the Mogollon Rim of northern Arizona. The new species appears most similar to V. vorhiesi Stahnke and V. deboerae Ayrey. The most distinguishing characteristic of this new species is the number of inner denticles (ID) found on the pedipalp fingers with six on the movable finger and usually five on the fixed finger, which more closely correlates with Vaejovis species from the mountains of southern Arizona rather than those geographically closer …

A Note On The Scorpions From The Pirin Mountains, Southwestern Bulgaria (Scorpiones: Buthidae, Euscorpiidae), Rolando Teruel, Victor Fet, Luis F. De Armas

Euscorpius

In the present note, four scorpion species are recorded from the Pirin Mountains in southwestern Bulgaria, including the first records for Bulgaria of both Mesobuthus gibbosus (Brullé, 1832) (Buthidae) and the “mingrelicus complex” of the genus Euscorpius Thorell, 1876 (Euscorpiidae) (the latter based upon an undetermined species). Also, E. hadzii Caporiacco, 1950 and another undetermined species of Euscorpius belonging to the “carpathicus complex” are recorded from Pirin. The taxonomic affinities of the taxa are discussed, as well as some biogeographical considerations about the scorpions of this poorly studied mountainous area.

A Scorpion From A Peatbog: The First Arthropod Fossil From The Late Viséan Of The Moscow Coal Basin, Victor Fet, Michael E. Soleglad, Yulia V. Mosseichik, Dmitry E. Shcherbakov

Euscorpius

This note describes a fossil fragment from the Upper Viséan (ca. 330 Ma), of the Moscow Coal Basin (Novgorod Region, Russia). The fossil is identified as the cuticle of a single leg segment (left femur) of a scorpion (Arachnida: Scorpiones), without any further taxonomic placement. The anatomical details of the fragment are given, along with ecological considerations. It is the first fossil scorpion record from Russia.

Alloscorpiops Wongpromi Sp. N. From Thailand And Laos (Scorpiones: Euscorpiidae: Scorpiopinae), František Kovařík, Michael E. Soleglad, Ondřej Košulič

Euscorpius

Alloscorpiops wongpromi sp. n. from Thailand and Laos is described and compared with all other species of the genus Alloscorpiops Vachon, 1980. A key is presented to all species of the genus. A. wongpromi sp. n. is characterized mainly by a higher number of trichobothria on the patella, which has 33–37 external and 21–22 ventral trichobothria, and a dark-colored telson. The subgenus Laoscorpiops Lourenço, 2013 is synonymized with the nominotypical subgenus, because it was based on misinterpretation of the trichobothrial pattern, with two ventral accessory trichobothria on the chela regarded as part of the external Eb series.

Response Of Male Centruroides Vittatus (Scorpiones: Buthidae) To Aerial And Substrate-Borne Chemical Signals, Steffany B. Steinmetz, Karen C. Bost, Douglas D. Gaffin

Euscorpius

Chemical signaling promotes mate location throughout numerous animal taxa. In this study we investigated the possibility that striped scorpions, Centruroides vittatus, use chemical signaling in the form of odor plumes or substrate-borne deposits as communication channels. A Y-shaped arena was constructed to test scorpions’ use of air-borne chemical cues in the detection of potential mates. A second, circular behavioral choice chamber was used to test male scorpions’ responses to female deposits by direct substrate contact. Male scorpions showed no tendency to move toward the female in tests of air-borne chemical transmission but they did demonstrate behavior associated with chemical …

The species collected belong to different ecomorpho-types, characteristic for the particular geographic position of Kashan. We report presence of two species …

A Powerful New Light Source For Ultraviolet Detection Of Scorpions In The Field, Graeme Lowe, Steven R. Kutcher, Doug Edwards

Euscorpius

We describe a new portable solid-state ultraviolet (UV) light that should greatly improve the ease and effectiveness of fluorescent detection of scorpions in the field. The design is based on an array of InGaN light emitting diodes (LEDs). It is in-expensive, lightweight, simple to implement, energetically efficient and mechanically rugged. Scorpion cuticular fluorescence excited by an LED array is 13-fold brighter than excitation by previously available fluorescent tube lamps drawing the same current from the battery.

High-Level Systematics And Phylogeny Of The Extant Scorpions (Scorpiones: Orthosterni), Michael E. Soleglad, Victor Fet

Euscorpius

A number of authors (e. g. Birula, 1917a, 1917b; Mello-Leitão, 1945; Stockwell, 1989) addressed above-level systematics of extant scorpions, and accepted the grouping of scorpion families in several superfamilies. At the same time, Kjellesvig-Waering (1986) classified all extant scorpions under the same superfamily, Scorpionoidea. Sissom (1990) and Fet et al. (2000) did not list any superfamilies, considering the systematic situation above family (and often at the family level as well) unresolved. Most recently, Lourenço (2000a) listed six superfamilies, largely following the unpublished but important study of Stockwell (1989). The goal of this paper is to address scorpion systematics and phylogeny …

The Scorpion Sternum: Structure And Phylogeny (Scorpiones: Orthosterni), Michael E. Soleglad, Victor Fet

Euscorpius

The structure of the sternum of all major Recent scorpion groups is analyzed in detail. Based on this analysis, two fundamental sternum types are identified, described and illustrated, type 1 and type 2. These sternum types are distinguished by criteria based on external and internal structural features. The sternum types described herein are offered as a replacement for the various characterizations used throughout the last 140 years which emphasize only gross overall shape and proportions. Phylogenetic and taxonomic ramifications of these new sternal types are discussed. The Carboniferous fossil scorpion Palaeopisthacanthus schucherti Petrunkevitch is assigned to sternum type 1 …

A Survey Of The Common Loon (Gavia Immer) Genome Reveals Patterns Of Natural Selection, Zach G. Gayk

All NMU Master's Theses

With rapid advances in Next-Generation Sequencing technology, comparative genomics has become a viable method for studying the adaptation of species to their environment at the genome level. I investigated this in common loons (Gavia immer)—for which molecular adaptation has not been characterized—by finding signatures of positive selection as evidence for genomic adaptation.

I used Illumina short read sequencing data from a single female common loon to produce a fragmented assembly of the common loon (Gavia immer) genome. The resulting assembly had a contig N50 of 814 bp, a total length of 767,326,331 bp, and 45.7 % …

Genetic Analyses Determine Connectivity Among Cave And Surface Populations Of The Jamaican Endemic Freshwater Crab Sesarma Fossarum In The Cockpit Country, Manuel Stemmer, Christoph D. Schubart

International Journal of Speleology

The Jamaican freshwater crab Sesarma fossarum (Decapoda: Brachyura: Sesarmidae) is endemic to western central Jamaica where it occurs in cave and surface streams of karst regions. In the present study, we examine the population genetic structure of the species, providing evidence for intraspecific differentiation and genetic substructure among twelve sampled populations. Interestingly, crabs from caves appear genetically undistinguishable from representatives of nearby surface waters, despite previously observed and described morphometric differentiation. In contrast, genetic isolation takes place among populations from rivers and caves belonging to different watersheds. In one case, even populations from different tributaries of the same river were …

P-29 Diversity And Species Turnover Of Late Cenozoic Ground Squirrels In The Meade Basin, Ks, H. Thomas Goodwin

Celebration of Research and Creative Scholarship

The Meade Basin of southwestern Kansas preserves one of the richest fossil sequences from the late Cenozoic of North America. An ongoing study has documented a rich record of fossils, especially rodents; established episodes of especially rapid species turnover (when species appear or disappear from the local record); and has attempted to relate these processes to environmental change inferred from stable isotope and other proxies for ancient climate. Here, I report on fossil squirrels from the record. At least 7 genera and 13 species are present in the composite record. Species turnover occurs throughout the record, but an especially high …

No Effect Of Host Species On Phenoloxidase Activity In A Mycophagous Beetle, Vincent A. Formica, Amanda Kar-Men Chan , '16

Biology Faculty Works

Ecological immunology is an interdisciplinary field that helps elucidate interactions between the environment and immune response. The host species individuals experience have profound effects on immune response in many species of insects. However, this conclusion comes from studies of herbivorous insects even though species of mycophagous insects also inhabit many different host species. The goal of this study was to determine if fungal host species as well as individual, sex, body size, and host patch predict one aspect of immune function, phenoloxidase activity (PO). We sampled a metapopulation of Bolitotherus cornutus, a mycophagous beetle in southwestern Virginia. B. cornutus live …

A Polyglot Approach To Bioinformatics Data Integration: A Phylogenetic Analysis Of Hiv-1, Steven Reisman, Thomas Hatzopoulos, Konstantin Laufer, George K. Thiruvathukal, Catherine Putonti

Bioinformatics Faculty Publications

As sequencing technologies continue to drop in price and increase in throughput, new challenges emerge for the management and accessibility of genomic sequence data. We have developed a pipeline for facilitating the storage, retrieval, and subsequent analysis of molecular data, integrating both sequence and metadata. Taking a polyglot approach involving multiple languages, libraries, and persistence mechanisms, sequence data can be aggregated from publicly available and local repositories. Data are exposed in the form of a RESTful web service, formatted for easy querying, and retrieved for downstream analyses. As a proof of concept, we have developed a resource for annotated HIV-1 …
