Observations On Regeneration Of The Pedipalp And Legs Of Scorpions, 2022 Marshall University
Observations On Regeneration Of The Pedipalp And Legs Of Scorpions, Martin Watz, Jason A. Dunlop
An Opisthacanthus asper (Peters, 1861) (Hormuridae) shows a relatively rare example of pedipalp regeneration in which the lost tibia and tarsus was replaced by a smaller, curved element of uncertain homology to either the fixed or free finger. A comparable abnormal palp described in the literature hints that pedipalps can only regenerate a structure of this form, regardless of the site of amputation. An Olivierus caucasicus (Nordmann, 1840) (Buthidae) is described in which claws (pretarsus) of leg III regenerated directly at the distal end of the tibia, while in leg IV the claws regenerated at the end of a truncated ...

Amphibians And Reptiles As Prey Of Heteroctenus Junceus (Scorpiones: Buthidae), With A Summary Of Vertebrate Predation By Scorpions In The West Indies, Tomás M. Rodríguez-Cabrera,, Ernesto Morell Savall, Rolando Teruel
Vertebrate predation by scorpions has been scarcely documented in the literature. Contrary to large scorpions of the genera Centruroides, Hadrurus, Opistophthalmus, and Pandinurus from North America and Africa, which are capable of subduing even small rodents and bats, West Indian scorpions of the genera Centruroides, Heteroctenus, and Tityus seem to limit their prey to amphibians and reptiles. Herein we present new cases of a frog (Osteopilus septentrionalis; Hylidae) and three lizards (Anolis allisoni, A. ophiolepis, and A. sagrei; Dactyloidae) preyed upon by Heteroctenus junceus (Herbst, 1800), at the time we summarize all cases of vertebrate predation by scorpions in the ...
Androctonus Turkiyensis Sp. N. From The Şanlıurfa Province, Turkey (Scorpiones: Buthidae), 2021 Marshall University
Androctonus Turkiyensis Sp. N. From The Şanlıurfa Province, Turkey (Scorpiones: Buthidae), Ersen A. Yağmur
A new species Androctonus turkiyensis sp. n. is described and illustrated from the Şanlıurfa Province of Turkey. The new species is compared with A. crassicauda (Olivier, 1807), which was previously misidentified from Turkey. A. crassicauda specimens used for comparison were collected from Kashan County (Iran), the type locality of this species; a neotype from Kashan is designated.
The First Troglobitic Scorpions From Hispaniola, Greater Antilles: Two New Species Of Cazierius Francke, 1978 (Scorpiones: Diplocentridae), Rolando Teruel, Solanlly Carrero Jiménez, Gabriel De Los Santos
Two new species of the Greater Antillean endemic scorpion genus Cazierius Francke, 1978, are herein described from the island of Hispaniola. They were found inside isolate limestone caves in the Dominican Republic and are fully troglomorphic, thus, apparently being strict troglobites that represent the first ever documented for this genus. The present additions raise the number of Hispaniolan species of both Cazierius and the family Diplocentridae Karsch, 1880, to five and ten, respectively.
Resource Allocation And Phenotypic Plasticity Of Simultaneous Hermaphroditic Turtle Barnacles (Chelonibia Testudinaria), 2021 Nova Southeastern University
Resource Allocation And Phenotypic Plasticity Of Simultaneous Hermaphroditic Turtle Barnacles (Chelonibia Testudinaria), Kevin C. Cash
All HCAS Student Capstones, Theses, and Dissertations
This research addresses the knowledge gap of phenotypic plasticity in a commonly found and important species of epizoic barnacle, Chelonibia testudinaria. Limited research has been published regarding how phenotypic expression is mediated the spatial distribution of barnacles on a mobile host. To investigate this potential relationship, barnacles were collected from the backs of turtles along the beaches of Fort Lauderdale Florida. These barnacles were assessed for various phenotypic traits as well as their corresponding spatial distribution on the turtle carapace. Barnacles were safely removed from the carapace using a chisel before their preservation in ethanol. Barnacles were then numbered according ...
The Correct Identity Of Centruroides Hoffmanni Armas, 1996 (Scorpiones: Buthidae), With The Description Of A New Species From Chiapas, Mexico, Luis De Armas, Rolando Teruel
The Mexican scorpion Centruroides hoffmanni Armas, 1996 was described on the basis of a supposed adult female (actually a juvenile) from La Gloria, Arriaga Municipality, southwest of the Chiapas State. In its redescription, this species was also recorded from the southeastern of Oaxaca State. Nevertheless, in the recent revision of the “thorellii” species-group of the genus Centruroides Marx, 1890, a new species from Chiapas was misidentified as C. hoffmanni and, also, an erroneous new diagnosis was given for C. hoffmanni. In the present contribution, this new species is named Centruroides concordia sp. n., and the correct identity of C. hoffmanni ...
Discovering Mechanisms Driving Adaptive Evolution In The Cross-Kingdom Fungal Pathogen Fusarium Oxysporum, 2021 University of Massachusetts Amherst
Discovering Mechanisms Driving Adaptive Evolution In The Cross-Kingdom Fungal Pathogen Fusarium Oxysporum, Dilay Hazal Ayhan
Fusarium oxysporum is a cross-kingdom pathogenic fungus that can cause vascular wilt disease in many economically important plants and local or disseminated infections in humans. Although it lacks a sexual stage in its life cycle, F. oxysporum can adapt to a wide range of hosts because of accessory chromosomes (ACs) which are enriched in host-specific genes and repeat content. This dissertation investigates the mechanisms that drive the adaptive evolution in the cross-kingdom pathogen F. oxysporum using comparative genomics and an experimental evolution approach. The first chapter compares phenotypes and genomes of a plant pathogenic isolate F. oxysporum f. sp. lycopersici ...

Phenotype Bias Determines How Natural Rna Structures Occupy The Morphospace Of All Possible Shapes, 2021 Gulf University for Science and Technology, Kuwait
Phenotype Bias Determines How Natural Rna Structures Occupy The Morphospace Of All Possible Shapes, Fatme Ghaddar, Dr Kamaludin Dingle, Dr Petr Sulc, Prof Ard A. Louis
Undergraduate Research Symposium
The relative prominence of developmental bias versus natural selection is a long standing controversy in evolutionary biology. Here we demonstrate quantitatively that developmental bias is the primary explanation for the occupation of the morphospace of RNA secondary structure (SS) shapes. By using the RNAshapes method to define coarse-grained SS classes, we can measure the frequencies that non-coding RNA SS shapes appear in nature. Our main findings are firstly that only the most frequent structures appear in nature; the vast majority of possible structures in the morphospace have not yet been explored. Secondly, and perhaps more surprisingly, these frequencies are accurately ...
A Reevaluation Of The Phylogeography Of The Chattahoochee Slimy Salamander (Plethodon Chattahoochee) Using Next-Generation Genomic Data, Jadin Cross
Symposium of Student Scholars
The Plethodon glutinosus species complex is a group of large-bodied, lungless salamanders that are widespread across the eastern United States. Species in this group are morphologically cryptic and were originally delimited using allozyme data, but in most cases, the extent of contemporary gene flow between named taxa has not be rigorously evaluated. The Appalachian Mountains of northern Georgia are home to several members of this group—including P. glutinosus, P. teyahalee, P. chlorobryonis, and P. chattahoochee. P. chattahoochee has been found to be especially cryptic both morphologically and genetically as both intraspecific genetic variation and species boundaries within the P ...
The Evolutionary Origins Of Autism Associated Genes And Their Role In Great Ape Socio-Communication, 2021 Kennesaw State University
The Evolutionary Origins Of Autism Associated Genes And Their Role In Great Ape Socio-Communication, Azeeza Abdulrauf, Martin Hudson, Susan M.E. Smith, Jared P. Taglialatela
Symposium of Student Scholars
Single nucleotide polymorphisms (SNPs) play a major role in socio-communicative behavior. For this study, the focus is on autism associated OXTR, AVPR1A, and FOXP2 SNPs, and the role they play in great apes. Prior research on the OXTR, AVPR1A, and FOXP2 SNPs show that they affect behavior skills such as understanding and controlling emotion, understanding the emotions of others, and communications skills. Great apes, such as bonobos, chimpanzees, and gorillas are the model, since they are our closest relatives in the animal kingdom capable of understanding complex communication. Each gene has at least two SNPS that are investigated in the ...
Laryngeal Vocals In Old World Locals: Air Sacs Usage In Bonobos, 2021 Kennesaw State University
Laryngeal Vocals In Old World Locals: Air Sacs Usage In Bonobos, Chelsea Trenbeath
Symposium of Student Scholars
Except for humans, extant great apes have evolutionarily conserved lateral ventricular air sacs extending from laryngeal saccules. Humans are the only species of Hominidae that lack this anatomical feature attached to the primary vocal apparatus. As we are the only species that produces spoken language, this association has led to hypothesis that the loss of lateral ventricular air sacs was necessary for the evolution of spoken language. However, why these sacs are conserved in all other hominids remains unclear. Computer modeling has indicated that air sacs may increase resonance properties, but there are no data from great apes indicating which ...
Fine-Scale Morphological Divergence Of Wing Trait Variables In Highly Fragmented Populations Of The Bog Copper Butterfly (Lycaena Epixanthe), Jessica L. T. Jeong
Undergraduate Student Research Internships Conference
Habitat fragmentation can adversely affect animal and plant species through subdividing their natural habitats into smaller, more isolated patches. Oftentimes, these isolated groups are subject to reduced dispersal and gene flow, leading to genetic divergence and, consequently, morphological divergence among populations. This study aims to quantify the morphological divergence of the bog copper butterfly, Lycaena epixanthe, between nine isolated bog sites in Algonquin Provincial Park, Ontario, via seven quantitative morphological traits in their wing pattern. Statistical analyses demonstrate significant differences in wing trait measurements between populations. As bog coppers are small, weak fliers with a strict host-plant dependency, it is ...
Testing For Character Displacement Between Two Abundant Stream Fishes, 2021 The University of Southern Mississippi
Testing For Character Displacement Between Two Abundant Stream Fishes, Amber Nations
Character displacement is a pattern that can be used to explain differences between similar species in sympatric and allopatric situations. Gause’s Principle explains that a niche can only be occupied by one species at a time, so character displacement may be a way for similar species in the same habitat to shift resource use and compensate in order for the species to coexist. The Southeastern United States offers a unique opportunity to study this pattern because the diversity of freshwater fauna is quite high. However, the question of “How did this region become so diverse?” remains unanswered. One way ...
Investigation Into The Evolution Of Heterogeneity Within Secondary Replicons And Their Maintenance In Genus Variovorax, 2021 California State University - San Bernardino
Investigation Into The Evolution Of Heterogeneity Within Secondary Replicons And Their Maintenance In Genus Variovorax, Christopher Ne Ville
Electronic Theses, Projects, and Dissertations
Approximately 10% of all bacterial genomes sequenced thus far contain a secondary replicon. This considerable genetic reservoir contains many potentially mobilizable elements, allowing for the formation of many unique secondary replicons. This property of bacterial populations vastly increases the genomic diversity available to species that effectively take up and maintain these replicons. Members of the genus Variovorax have extensive heterogeneity in genome architecture, including sequenced isolates containing plasmids, megaplasmids, and chromids. Using available Illumina data on the NCBI database, we have completed these assemblies using 3rd generation sequencing methods on 17 members of this genus. We have sequenced, assembled ...

The goal of this club was for students to expand their knowledge on wildlife that exists both in and outside of Nebraska and for them to get a better idea the types of wildlife they might be able to find within the state. In addition, an objective of this club was to spark curiosity so that the kids might try to further explore aspects of wildlife on their own.
Molecular Phylogeny Of Cave Dwelling Eremogryllodes Crickets (Orthoptera, Myrmecophilidae) Across Zagros Mountains And Southern Iran, Mohadeseh Sadat Tahami, Mina Hojat-Ansari, Anna Namyatova, Saber Sadeghi
International Journal of Speleology
Recently, several new species and subspecies from the genus Eremogryllodes Chopard, 1929 (Insecta: Orthoptera: Myrmecophilidae) inhabiting caves of Iran, have been described based on morphology. The high variation of genitalia structure along with high similarity of external morphology between populations hamper the precise species identification. Thus, molecular approaches are critical to determine the taxonomic positions of species/subspecies of this genus. Here we provide the molecular phylogeny, based on the 16S rRNA mitochondrial gene, of recently described species of Eremogryllodes along with some unidentified specimens from the same region. The results support the monophyly of the family Myrmecophilidae. The topology ...
