On Fabre’S Traces: An Important Contributor To The Knowledge Of Buthus Occitanus (Amoreux, 1789), Marco Colombo
On Fabre’S Traces: An Important Contributor To The Knowledge Of Buthus Occitanus (Amoreux, 1789), Marco Colombo
Euscorpius
Jean-Henri Casimir Fabre (1823–1915) has probably been one of the most important entomologists of the world in the last two centuries, leaving to posterity a huge amount of manuscripts and books. The Languedoc yellow scorpion, Buthus occitanus (Amoreaux, 1789), has been one of his objects of study: many of its behaviours, including the famous “promenade a deux”, have been described by the careful eye of the French entomologist, giving an interesting contribution to modern scorpiology

The First Record Of The Family Euscorpiidae (Arachnida: Scorpiones) From Central China, With A Key Of Chinese Species Of The Genus Scorpiops, Zhi-Yong Di, Ya-Wen He, Zhi-Jian Cao, Ying-Liang Wu, Wen-Xin Li
Euscorpius
The genus Scorpiops (Euscorpiidae) is recorded for the first time in Central China. Two immature specimens of a form belonging to Scorpiops hardwickii (Gervais, 1843) “complex” were collected from Huzhaoshan Mountains in Hubei Province. A discussion of Chinese species of genus Scorpiops is provided, as well as a key of Scorpiops from China.
Scorpions In Ancient Egypt, Hisham K. El-Hennawy
Scorpions In Ancient Egypt, Hisham K. El-Hennawy
Euscorpius
The ancient Egyptians knew the scorpion and its toxicity, and venerated it since pre-dynastic era. They used the scorpion as a king's name, a name of a nome (county), and a symbol to their goddess, Serqet, that protects the body and the viscera of the dead, and that accompanies them in their journey to the afterlife. They had medical prescriptions and magical spells to heal the stings. Since the 5th dynasty, the title of a “Follower of Serket” was given to clever physicians. Scorpions are most famously depicted on Horus Cippus, a talisman featuring Horus the Child holding in his …
Pectine Development In Scorpion Embryos And First And Second Instars, Roger D. Farley
Pectine Development In Scorpion Embryos And First And Second Instars, Roger D. Farley
Euscorpius
The pectines are complex sensory organs that extend from the ventral surface of the anterior opisthosoma (mesosoma) in all extant scorpions and nearly all the fossil scorpions that have been examined. The pectines are synapomorphic for the Order Scorpiones. In this investigation, the scanning electron microscope (SEM) was used to study the development of the pectines in representatives from five scorpion families. In the more basal families (e.g., Vaejovidae) with apoikogenic development, the pectines start to develop early with enlargement of the limb buds on the third opisthosomal segment. The primordial pectines become elongate lobes attached to the ventro-lateral surface …
The First Record Of Upper Permian And Lower Triassic Scorpions From Russia (Chelicerata: Scorpiones), Victor Fet, Dmitry E. Shcherbakov, Michael E. Soleglad
The First Record Of Upper Permian And Lower Triassic Scorpions From Russia (Chelicerata: Scorpiones), Victor Fet, Dmitry E. Shcherbakov, Michael E. Soleglad
Euscorpius
Several small fragments of fossil scorpions are reported from two localities in Vologda Province, Russia, representing the Upper Permian (Severodvinian, correlated to Wuchiapingian) (Isady) and Lower Triassic just above the Permian-Triassic boundary (Induan) (Nedubrovo). Most observed structures are not diagnostic at genus or family level. The Isady leg fragment possesses ungues (claws), which are both denticulated and setaceous, and resembles a Carboniferous Eobuthus sp. (Eobuthidae). It is the latest record of this type of ungues, which are known in some Paleozoic scorpions (extinct suborder Mesoscorpiones); all extant scorpions have smooth claws without denticulation or setation.
In Situ Infrared Videography Of Sand Scorpion Nighttime Surface Activity, Douglas D. Gaffin
In Situ Infrared Videography Of Sand Scorpion Nighttime Surface Activity, Douglas D. Gaffin
Euscorpius
Sand scorpions make burrows from which they emerge at night to seek mates and prey. Previous ecological studies have documented scorpion activities on the sand surface. Few studies, however, have videotaped scorpion movements in the context of understanding their sensory neurobiology. Our objective is to understand which signals guide scorpions as they emerge from and return to their burrows. Candidate stimuli include chemical trails, footsteps, celestial patterns, geomagnetic cues, humidity and/or temperature gradients, distinctive scents from the burrow, seismic echolocation, memory, or landmark orientation. We videotaped scorpions to learn whether they return to their burrows by the same path they …
Further Considerations On The Species Of The Genus Orthochirus Karsch, 1891 From Africa, With Description Of Three New Species (Scorpiones: Buthidae), Wilson R. Lourenço, Elise-Anne Leguin
Further Considerations On The Species Of The Genus Orthochirus Karsch, 1891 From Africa, With Description Of Three New Species (Scorpiones: Buthidae), Wilson R. Lourenço, Elise-Anne Leguin
Euscorpius
New considerations are proposed regarding the African species of the genus Orthochirus Karsch, 1891. Two species, Orthochirus aristidis (Simon, 1882) and Orthochirus innesi Simon, 1910 have been the subject of several publications in the past decades; however, doubts remain about their exact identity and range of geographical distribution. In this note, their taxonomic status is reinvestigated. The type material is revised and the lectotype and paralectotypes are designated for O. aristidis. Revised diagnoses and illustrations are proposed for both species, and these are confirmed as valid. Three new species are described from Algeria, Morocco, and Mauritania. The total number …
Polymorphism And Hybridization In Species Of Hottentotta Birula, 1908 (Scorpiones: Buthidae), Wilson R. Lourenço, Eric Ythier, Mark Stockmann, John L. Cloudsley-Thompson
Polymorphism And Hybridization In Species Of Hottentotta Birula, 1908 (Scorpiones: Buthidae), Wilson R. Lourenço, Eric Ythier, Mark Stockmann, John L. Cloudsley-Thompson
Euscorpius
A new and well documented case of hybridization among scorpions is presented. It was obtained under laboratory conditions between Hottentotta jayakari (Pocock) and Hottentotta salei (Vachon) specimens of which had been collected in the northern and southern regions of Oman. Hybrids were successfully produced not only from F0 males and females, but also from F1 males and females, thereby attesting to the fact that the first generation obtained (F1), was completely fertile. Both F1 and F2 broods were composed of dark and pale morphs, indicating that the juveniles could inherit either one or …
Redescription Of Tityus Pictus Pocock, 1893 And Tityus Smithii Pocock, 1893, With Notes On The Tityus Species From The Lesser Antilles (Scorpiones: Buthidae), Rolando Teruel
Euscorpius
In the present paper, the taxonomic status of Tityus pictus Pocock, 1893 and all of its junior synonyms is revised. Tityus smithii Pocock, 1893 is restored as a valid species, and the subspecies Tityus smithii microdon Pocock, 1893 (currently T. pictus microdon) is regarded as its junior synonym. Both T. pictus and T. smithii are redescribed, supplementary information on their morphological variability are given, and their geographical distribution is up- dated, including a new locality record for the latter. Also, the taxonomic position and relationships of all Lesser Antillean species of the genus are clarified: it is demonstrated that …

Determining The Composition Of The Dwelling Tubes Of Antarctic Pterobranchs, Lukasz J. Sewera
Determining The Composition Of The Dwelling Tubes Of Antarctic Pterobranchs, Lukasz J. Sewera
Honors Projects
Pterobranchs are a group of marine invertebrates within the Hemichordata, which share characteristics with both chordates and echinoderms. Pterobranchs live in colonies of secreted tubes, coenicia, which are composed of a gelatinous material of unknown composition. Visually, the tubes appear similar to the tunic of tunicates, a group of invertebrates within the Chordata. The nonproteinaceous tunic of tunicates is composed of cellulose, which is unusual. The goal of this study was to determine the composition of the pterobranch coenicium. Some aspects of pterobranch phylogeny are still unclear even after multiple molecular and morphological studies. Identification of any new shared characteristics …

The Genus Butheoloides Hirst, 1925 (Scorpiones, Buthidae) In Morocco, With A Description Of А New Species, Wilson R. Lourenço, Oulaid Touloun, Ali Ali Boumezzough
Euscorpius
A new species belonging to the genus Butheoloides Hirst, 1925 (subgenus Butheoloides Hirst, 1925) (Scorpiones, Buthidae) is described from two localities in Morocco: north of Sidi Ifni in the southern coast and Sidi Moussa west of Tiznit. With the description of Butheoloides (Butheoloides) littoralis sp. n., the total number of species of this genus known from Morocco is raised to five. This makes Morocco the region in Africa with the highest diversity for Butheoloides species.
Multilocus And Parametric Analyses Of The Evolutionary History Of The Amazonian Peacock Cichlids, The Genus Cichla (Teleostei: Cichlidae), Stuart Clayton Willis
Multilocus And Parametric Analyses Of The Evolutionary History Of The Amazonian Peacock Cichlids, The Genus Cichla (Teleostei: Cichlidae), Stuart Clayton Willis
School of Biological Sciences: Dissertations, Theses, and Student Research
Accurate knowledge of species boundaries and species phylogeny are fundamental to testing hypotheses of recent evolutionary processes, but the estimation of these partitions is challenging due both to inherent confusion about what is being estimated as well as the data available to estimate them. Using multilocus data from mtDNA, microsatellites, and nuclear locus sequences of over 1100 individuals, we delimited eight separately evolving species of Cichla rather than the 15 described. Among species we found evidence of rare but widespread introgressive hybridization, while within these species we observed evidence of long-term gene exchange and constrained evolutionary trajectories. In most cases …

Phylogeography Of Northern Populations Of The Black-Tailed Rattlesnake (Crotalus Molossus Baird And Girard, 1853) With The Revalidation Of C. Ornatus Hallowell, 1854, Christopher Anderson
Open Access Theses & Dissertations
The black-tailed rattlesnake (Crotalus molossus Baird and Girard, 1853) is a wide-ranging species complex with representatives from the southwestern United States through the highlands of central and southern Mexico. The systematics of this group has received little attention and in the past six decades only two taxonomic revisions have been proposed (the transfer of C. basiliscus oaxacus to C. molossus and the elevation of C. m. estebanensis to full species). However, a recent revision of the Neotropical rattlesnakes (C. durissus and C. simus) recovered a polyphyletic C. molossus. Sequenced data were obtained from three mitochondrial genes …

Reconstructing Species Responses To Past Climatic Changes Using Niche Modeling And Genetic Data, Tereza Jezkova
UNLV Theses, Dissertations, Professional Papers, and Capstones
Glacial – interglacial cycles have a pronounced impact on species distributions and genetic structure. Many species shift their distributions to lower latitudes and altitudes during the colder glacial periods and expand northwards and up the elevation during warmer interglacial periods. Some species however are capable of adapting to changing environment which allows them to persist in place despite climatic changes. I explored how climatic changes after the last glacial maximum (LGM) effected two species inhabiting the deserts of western North America: one mammal (Chisel-toothed Kangaroo Rat, Dipodomys microps) and one reptile (Desert Horned Lizard, Phrynosoma platyrhinos). I used …

Ecology And Relationships Of Rhabdias Spp. (Nematoda: Rhabdiasidae) From North American Amphibians And Reptiles, Gabriel J. Langford
School of Biological Sciences: Dissertations, Theses, and Student Research
Lungworms of the cosmopolitan genus Rhabdias (Nematoda: Rhabdiasidae) are among the most common parasites of amphibians and squamate reptiles. The life cycles, life histories, host specificities, and evolutionary relationships of Rhabdias spp. were studied through examination of their free-living and parasitic stages in amphibians and reptiles. This study found free-living development of anuran lungworms was primarily limited to heterogonic reproduction, whereas snake lungworms primarily reproduced homogonically. Infective anuran lungworms penetrated the skin of frogs and toads; in contrast, snake lungworms penetrated snake esophageal tissue during per os infections. Our molecular phylogeny strongly supported separate clades for anuran and snake lungworms, …

Molecular Systematics And Phylogeography Of The Genus Richardsonius, Derek Dee Houston
Molecular Systematics And Phylogeography Of The Genus Richardsonius, Derek Dee Houston
UNLV Theses, Dissertations, Professional Papers, and Capstones
The complex geological and climatic events that significantly altered the landscape throughout the Cenozoic Era impacted the diversification of many North American taxa, including freshwater fishes. Here, I employ an array of phylogenetic analyses using a multiple gene tree approach to address several questions regarding the phylogenetic relationships of the North American cyprinid genus Richardsonius and two other closely related genera, Clinostomus and Iotichthys. I also use divergence time estimates generated using fossil calibrations to qualitatively assess the phylogeographic implications of evolution within and among these three genera. Mitochondrial and nuclear DNA sequences show a sister relationship between Iotichthys and …

Mechanical Properties Of The Integument Of The Common Gartersnake, Thamnophis Sirtalis (Serpentes: Colubridae), Gabriel Rivera
Biological Sciences Theses & Dissertations
The evolution of the ophidian feeding mechanism has involved substantial morphological restructuring associated with the ability to ingest relatively large prey. Previous studies examining the morphological consequences of macrophagy have concentrated on modifications of the skull and cephalic musculature. Although it is evident that macrophagy requires highly compliant skin, the mechanical properties of the ophidian integument have received limited attention, particularly in the context of feeding. I examined mechanical properties of skin along the body axis in male Thamnophis sirtalis (Colubridae). From each of 11 specimens, I examined nine circumferential strips of skin, each spanning 10 ventral scales, spaced at …
