Scorpions In The Modern Cuban Culture: An Introductory Iconography, Luis F. De Armas

Euscorpius

Some graphic examples of the role of scorpions in the present-day culture of Cuba are presented. They include tattoos, jewels, carpets, caps, and drawings by children, among other objects of personal or social usage. Increased use of this arachnid as a cultural element among Cuban people during last 50 years seems to be directly related with globalization, mostly through the TV and movies.

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

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

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

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

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

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

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 …

Factors That Affect Harem Stability In A Feral Horse (Equus Caballus) Population On Shackleford Banks Island, Nc, Jessa Madosky

LSU New Orleans Theses and Dissertations

Mammal species often live in social groups, but the factors that promote group cohesion can be difficult to analyze due to the prevalence of strong group affiliations. Feral horses maintain stable harems of one or two males and several females, and harem stability is strongly related to individual fitness. Anecdotal evidence and an early study in the non-breeding season suggest that management of the Shackleford Banks island horses with immunocontraception reduces harem stability in the population, providing an opportunity to study the factors that influence harem stability. I investigated the effects of the immunocontraceptive PZP on harem stability during the …

Patterns Of Transience, Sex Bias, And Body Mass In Open-Habitat Rodent Populations, Stephen Edward Rice

Biological Sciences Theses & Dissertations

Rodents are assumed to live their lives in circumscribed (natal) areas with males being more prone to disperse than females and juveniles more prone to disperse than adults. To test these assumptions we examined the initial captures of geographic populations of hispid cotton rat, meadow vole, prairie vole, and marsh rice rat obtained through capture-mark-recapture methods. Capture records were obtained from Kansas and Illinois from long-term studies, and through live-trapping in Chesapeake, Virginia. I evaluated proportions of residents and transients, adults and juveniles, and males and females for significant differences among seasons, years, and geographic locations. The overall body masses …

Exploring Sources Of Selection On The Multimodal Courtship Displays Of Two Sister Species Of Wolf Spiders: Schizocosa Crassipalpata And Schizocosa Bilineata, Mitch D. Bern

School of Biological Sciences: Dissertations, Theses, and Student Research

We examined multiple sources of selection on the multimodal courtship display of two sister species of wolf spiders, Schizocosa crassipalpata and Schizocosa bilineata. We first experimentally altered body condition in these two species by employing divergent diet treatments. We then tested for differences in adult male seismic courtship displays, visual courtship displays, and foreleg morphology; as well as adult female foreleg morphology. We then simultaneously examined both content and efficacy-based sources of selection on the visual and seismic multimodal courtship display of both species by conducting mate choice trials with high and low diet individuals across manipulated signaling environments …

The Complexities Of Wolf Spider Communication: Exploring Courtship Signal Function In Rabidosa Rabida, Dustin J. Wilgers

School of Biological Sciences: Dissertations, Theses, and Student Research

Evidence of signal complexity is seemingly pervasive across animal communication systems. Exploring signal function may provide insight into how these displays evolved and are maintained. This dissertation examines the courtship signal function in a grassland wolf spider. Rabidosa rabida lives in an extremely complex environment, and males use complex displays incorporating both visual and seismic modalities. Using several approaches I provide insight into the content and efficacy of the various signal components, as well as how variation in these displays influence female mating decisions in isolation and combined.

First, I manipulated male and female body condition using diet quantity manipulations …

Rats As Forest Pests In Southeastern Virginia: Girdling By The Hispid Cotton Rat Sigmodon Hispidus As A Significant Source Of Mortality Of Loblolly Pines (Pinus Taeda) In A Successional Pine Forest, Robyn M. Nadolny

Biological Sciences Theses & Dissertations

The hispid cotton rat (Sigmodon hispidus) is a common field rodent throughout the southeastern US, where volunteer loblolly pine trees (Pinus taeda) invade open space and begin the process of ecological succession from field to pine forest. Recent analysis of the diet of S. hispidus indicates that loblolly pine bark is stripped and eaten during the winter months. In this study, we explored the extent of rodent girdling on a 1.23 ha grid in a successional pine forest in southeastern Virginia. During the winter of 2005 we observed damage to 65% of trees in our study area, with 98% …

Redescription And Taxonomic Position Of Tityus Atriventer Pocock, 1897 (Scorpiones: Buthidae), Rolando Teruel, František Kovařík

Euscorpius

The largely neglected Lesser Antillean scorpion Tityus atriventer Pocock, 1897 is herein redescribed, after study of the two syntypes and one additional adult male. The latter was recently collected from Union Island (about 55 km northeast of Grenada), and it implies the first published finding of this species after its original description, and the first record of the species both outside the type-locality and from the Grenadines islands. The taxonomic position of T. atriventer is clarified (including designation of a lectotype and a paralectotype), its diagnosis is updated, a fully illustrated redescription is presented according to the current taxonomy of …

Spring Field Report, March 2011 To May 2011, W. Ross Silcock

Nebraska Bird Review

There was a nice mix of interesting phenomena this spring, notably a big influx of migrant warblers. Species that are normally uncommon were reported in good numbers, 30 or more each: Chestnut-sided, Magnolia, Blackburnian, Palm, and Northern Waterthrush, and species that normally occur in very low numbers approached double digits: Blue-winged, Golden-winged, Cape May, and Baybreasted. Southeastern species continue to expand in se. Nebraska, notably Cerulean and Kentucky Warblers and Summer Tanager. A few rarities showed up, most spectacular an alternate-plumaged female Red Phalarope, the first such record for Nebraska, which was captured on video by Nebraska Non-Game TV. Other …
