Examining Population Structure Of Cismontane And Desert Populations Of Zebra-Tailed Lizards (Callisaurus Draconoides) Using Mitochondrial And Nuclear Intron Dna., Lauren Nicole Morrison

Electronic Theses, Projects, and Dissertations

Callisaurus draconoides, also known as the Zebra-Tailed lizard, belongs to the family Phrynosomatidae family (Pianka, et al. 1972). C. draconoides is a widespread desert lizard found western North America. In California, this species can be found in the Mojave and Colorado Deserts. There are currently several populations that reside in the San Bernardino basin on the cismontane side of the Transverse and Peninsular ranges. These mountain ranges have the potential to have isolated the cismontane populations from their typical desert ranges. In addition, geological passes have the potential to serve as migration corridor between the Deserts and cismontane regions. The …

Scorpions Of The Horn Of Africa (Arachnida: Scorpiones) Part Xxxi. Two New Genera From Somaliland: Sanaag Gen. N. And Sahil Gen. N. (Buthidae), František Kovařík

Euscorpius

Two new monotypic buthid genera are described: Sanaag gen. n. and Sahil gen. n. from Somaliland, both belonging to the ‘Buthus’ group. Sanaag gen. n. (type species Gint maidensis Kovařík et al., 2018) differs from Gint Kovařík et al., 2013 in the structure of its hemispermatophore, which has a large, tall, subtriangular hook-like basal lobe, and in the shape of its telson which is rather bulbous. Sahil gen. n. (type species Sahil elmii sp. n.) differs from all morphologically similar small-sized genera of the Horn of Africa in having the ventral aspect of cheliceral fixed finger with two denticles, …

Reproductive Characteristics Of The Stripetail Darter (Etheostoma Kennicotti) Relative To Monogenean Gill Parasite Infection In Estill Fork In North Alabama, Joy L. Garcia, Zeina Celine Sleiman, Corinne N. Preacher, Bruce Stallsmith

Southeastern Fishes Council Proceedings

What relationship exists between Aethycteron sp. gill parasite infection and the reproductive characteristics of stripetail darters, Etheostoma kennicotti? 450 E. kennicotti were collected over 11 months from Estill Fork in Jackson County, Alabama. Gonads were removed and photographed. All oocytes were counted and then classified into one of four developmental stages based on size and appearance. Gill parasites belonging to the monogenean genus Aethycteron were excised, photographed, and counted. Sexual dimorphism in length and mass was observed in E. kennicotti. The number of males found at the 25> mm SL range far outnumbered the females while almost all …

In addition to the analyses of external morphology and hemispermatophore, we have provided descriptions of the karyotypes of P. dorisae sp. n. and P. quincyae sp. n. Despite the presence of multivalents (CVIII and CXIV), both species exhibit karyotypes with 2n=16 …

Teaching Evolutionary Principles With Ai Image Generators, Jacqueline Garnett

Generative AI Teaching Activities

The purpose of this assignment is for students to practice constructing phylogenies using the principle of parsimony. In this activity, students will use an AI Image Generator to create a grid of images of the same organism and identify a series of traits that vary to build a possible phylogenetic tree.

Alfred Russel Wallace Notes 30. Wallace A Theist? Part I., Charles H. Smith

Faculty/Staff Personal Papers

Alfred Russel Wallace (1823−1913) has been portrayed as a ‘theist’ on a large number of occasions from his own time on to the present. In this, the first of a two part work, this assessment is questioned. In part one, the matter of Wallace’s personal philosophy and spiritual orientation is explored, the conclusion being that Wallace was a lifelong agnostic who can hardly be aligned with theism.

The Wild Tomato Clade Offers Insights Into Fleshy Fruit Trait Evolution At The Phenotypic And Molecular Levels, Jacob R. Barnett

Doctoral Dissertations

Biologists have long been fascinated by the diversity of fleshy fruits, yet questions remain as to how this variety has evolved. According to the dispersal syndrome hypothesis, flowering plants improved their reproductive success by producing fleshy fruits with appealing combinations of traits that attract animal dispersers. However, animal preferences may not be the only selective pressure driving fruit trait diversity—conflicting forces include damage-inflicting seed predators and pathogens, abiotic habitat conditions, or constraints stemming from non-adaptive mechanical, developmental, or phylogenetic limitations. Few studies have examined the early stages of fleshy fruit evolution across an entire clade of recently diverged plant species. …

Species Delimitation Of Slimy Salamanders, Plethodon Kisatchie And Plethodon Mississippi, Across The Lower Mississippi River, Brock Hunter Stevenson

Master's Theses

Species are fundamental units of biodiversity yet delimiting species can be challenging. Slimy Salamanders of the Plethodon glutinosus species complex are a classic example of cryptic species for which species boundaries and relationships have proved difficult to determine. Once thought to be a single species ranging across the eastern United States, protein analysis revealed high genetic divergences among geographically distinct groups of populations, leading to 16 species being recognized within the group. Two of these species, the Louisiana Slimy Salamander (Plethodon kisatchie) and the Mississippi Slimy Salamander (Plethodon mississippi), are closely related but occur on opposite sides of the Mississippi …

A Survey Of Proximal Sensilla Associated With Denticle Subrows On Scorpion Pedipalp Fingers (Arachnida: Scorpiones), With Observations On Scorpion Fluorescence, Graeme Lowe, Victor Fet

Euscorpius

Sensilla on the dentate margins of scorpion pedipalp fingers, associated with denticle subrows or terminal denticles, were surveyed by white light, UV fluorescence and scanning electron microscopy. A total of 163 species belonging to 103 genera from 19 families were examined, representing all major phylogenetic lineages in the order. In the majority of species (141/152) with dentition organized into linear subrows of median denticles, a small socketed sensillum with a short shaft was observed at the proximal terminus of each subrow, termed a ‘subrow proximal sensilla’ (SPS). With few exceptions, SPS were non-fluorescent (‘Type N’) in buthids, and fluorescent (‘Type …
