Survivorship And Breeding Dispersal Patterns Of A Migratory, Socially Monogamous Passerine; The Scissor-Tailed Flycatcher (Tyrannus Forficatus), Adam John Becker

Dissertations and Theses

Survivorship (the likelihood of survival from one year to the next) and breeding dispersal (movement between breeding seasons) exhibit considerable variability at both the inter- and intraspecific levels. Using eight years of data (2008-2015), from my study site in southwest Oklahoma, I characterized survivorship and breeding dispersal of the Scissor-tailed Flycatcher (Tyrannus forficatus) in a mixed-grass prairie ecoregion. My results suggest that estimated survivorship of Scissor-tailed Flycatchers is low, especially to the congeneric Eastern Kingbird (T. tyrannus), and was likely underestimated due to the tendency of Scissor-tailed Flycatchers to disperse long distances.

Mechanical Self-Assembly Of A Strain-Engineered Flexible Layer: Wrinkling, Rolling, And Twisting, Zi Chen, Gaoshan Huang, Ian Trase, Xiaomin Han, Yongfeng Mei

Dartmouth Scholarship

Self-shaping of curved structures, especially those involving flexible thin layers, is attracting increasing attention because of their broad potential applications in, e.g., nanoelectromechanical andmicroelectromechanical systems, sensors, artificial skins, stretchable electronics, robotics, and drug delivery. Here, we provide an overview of recent experimental, theoretical, and computational studies on the mechanical self-assembly of strain-engineered thin layers, with an emphasis on systems in which the competition between bending and stretching energy gives rise to a variety of deformations, such as wrinkling, rolling, and twisting. We address the principle of mechanical instabilities, which is often manifested in wrinkling or multistability of strain-engineered thin layers. …

Voltammetric Analysis Of Mixtures Of Molten Eutectic Licl-Kcl Containing Lacl3 And Thcl4 For Concentration And Diffusion Coefficient Measurement, Zhong-Hang Wang, Devin Rappleye, Michael F. Simpson

Faculty Publications

Several electrochemical techniques, including cyclic voltammetry (CV), chronopotentiometry-open circuit potential (CP-OCP), chronoamperometry (CA) and normal pulse voltammetry (NPV) were applied to the eutectic LiCl-KCl melt containing LaCl₃ and ThCl₄ at 773K. The dependence of diffusion coefficient of La(III) on concentration of LaCl₃ was investigated by using CV, CP and CA. As the concentration of LaCl3 increases, the D_La(III) value obtained from CV gradually decreases, while the values derived from CA and CP exhibit a dome-shaped variation trend. In the LiCl-KCl-LaCl₃-ThCl₄ system, the diffusion coefficients of La(III) and Th(IV) are both approximately constant …

Analyses Of Amber Mutants Of Salmonella Phage Spn3us, Andrea Denisse Benítez Quintana

Theses

The giant Salmonella enterica phage SPN3US belongs to the ϕKZ-related phages which are amongst the most complex virions of prokaryotic viruses, even more complex than most eukaryotic viruses. SPN3US for example assigns 46% of its 240kbp genome to code for virion proteins. We have limited knowledge about these giant phages as they encode extremely diverged genes, from other phages and even to one another. The ϕKZ-related phages possess large genomes and correspondingly large and complex capsids, two sets of fragmented RNAP β and β’-like proteins and they also exhibit an unusual replication having a DNA polymerase split into two polypeptides. …

Sex-Specific Fungal Communities Of The Dioicous Moss Ceratodon Purpureus, Mehmet Ali Balkan

Dissertations and Theses

Mosses display a number of hallmark life history traits that influence their ecology at the population and community level. The long lived separation of sexes observed in the haploid gametophyte (dioicy) is one such feature of particular importance, as it is observed in the majority of bryophytes and creates intraspecific specialization of male and female individuals.

The prevalence of sexually dimorphic mosses raises the possibility of sex-specific interactions with fungi as observed in some vascular plants. Here I investigated how moss sex shapes fungal communities associated with gametophytic tissues of the ubiquitous moss, Ceratodon purpureus. Using greenhouse populations of …

The Geographic Pattern Of Distribution Of The Genus Rhopalurus Thorell, 1876 In The Guayana-Amazon Region (Scorpiones: Buthidae), Wilson R. Lourenço

Euscorpius

A new discussion is proposed on the geographic patterns of distribution presented by the species of the genus Rhopalurus Thorell, inhabiting the savannah formations of the northern South America. Two lineages of Rhopalurus species are defined for this region, each one containing forms with very weak morphological differences, a consequence of only a minor process of differentiation. The observed pattern of distribution and differentiation is suggested to be directly associated with more or less recent palaeoclimatic vicissitudes, which took place in tropical South America during Pleistocene. Two new subspecies are also described, representing new records of Rhopalurus for Brazil and …

Etudes On Iurids, Iii. Revision Of The Genus Iurus Thorell, 1876 (Scorpiones: Iuridae), With A Description Of Two New Species From Turkey, František Kovařík, Victor Fet, Michael E. Soleglad, Ersen Aydın Yağmur

Euscorpius

This revision is based on a comprehensive analysis of largely new, very extensive material encompassing 341 specimens (58 from Greece and 283 from Turkey). The type species Iurus dufoureius (Brullé, 1832) is restricted to Greece. Iurus asiaticus Birula, 1903 is confirmed as a distinct species, limited to eastern Anatolia. Most widespread in southern Turkey is another species, Iurus kraepelini von Ubisch, 1922, which is here restored from synonymy. We also describe two new species from Turkey: Iurus kadleci, sp. nov. from Antalya and Mersin Provinces (sympatric with I. kraepelini), and Iurus kinzelbachi, sp. nov. from İzmir and …

Contributions To Scorpion Systematics. Iii. Subfamilies Smeringurinae And Syntropinae (Scorpiones: Vaejovidae), Michael E. Soleglad, Victor Fet

Euscorpius

Stockwell (1989), in an unpublished revision, suggested splitting the family Vaejovidae in two subfamilies, introducing also four tribes and four new genera. These results have not been reevaluated for 20 years. Here, we establish a new subfamily Smeringurinae, subfam. nov., with two tribes, four genera, and 40 species and subspecies. The subfamily Smeringurinae includes two tribes: Smeringurini, trib. nov. and Paravaejovini, trib. nov. The tribe Smeringurini includes three genera: Paruroctonus Werner, 1934; Smeringurus Haradon, 1983; and Vejovoidus Stahnke, 1974. The tribe Paravaejovini includes the genus Paravaejovis Williams, 1980. We restore from synonymy the subfamily Syntropinae Kraepelin, 1905, and …

A New Scorpion Genus Representing A Primitive Taxon Of Tribe Stahnkeini, With A Description Of A New Species From Sonora, Mexico (Scorpiones: Vaejovidae), Matthew R. Graham, Michael E. Soleglad

Euscorpius

A new scorpion genus, Gertschius gen. nov., and species, Gertschius crassicorpus sp. nov., (Scorpiones: Vaejovidae) from Sonora, Mexico is described. Gertschius exhibits a reduced modification of the basal pectinal teeth in the female holotype and serration of the chelal finger denticles is limited to the median denticles (MD), thus we consider it a relict member of tribe Stahnkeini. Serradigitus agilis Sissom et Stockwell, 1991, is transferred to this new genus; Gertschius agilis, comb. nov.

Hairy Canola (Brasssica Napus) Re-Visited: Down-Regulating Ttg1 In An Atgl3-Enhanced Hairy Leaf Background Improves Growth, Leaf Trichome Coverage, And Metabolite Gene Expression Diversity, Ushan I. Alahakoon, Ali Taheri, Naghabushana K. Nayidu, Delwin Epp, Min Yu, Isobel Parkin, Dwayne Hegedus, Peta Bonham-Smith, Margaret Y. Gruber

Agricultural and Environmental Sciences Faculty Research

Background

Through evolution, some plants have developed natural resistance to insects by having hairs (trichomes) on leaves and other tissues. The hairy trait has been neglected in Brassica breeding programs, which mainly focus on disease resistance, yield, and overall crop productivity. In Arabidopsis, a network of three classes of proteins consisting of TTG1 (a WD40 repeat protein), GL3 (a bHLH factor) and GL1 (a MYB transcription factor), activates trichome initiation and patterning. Introduction of a trichome regulatory gene AtGL3 from Arabidopsis into semi-glabrous Brassica napus resulted in hairy canola plants which showed tolerance to flea beetles and diamondback moths; however …
