Seasonal Testicular Histology And Acystic Lobular Spermatogenesis In The Western Lesser Siren, Siren Intermedia Nettingi (Caudata: Sirenidae), Stanley E. Trauth
Seasonal Testicular Histology And Acystic Lobular Spermatogenesis In The Western Lesser Siren, Siren Intermedia Nettingi (Caudata: Sirenidae), Stanley E. Trauth
Journal of the Arkansas Academy of Science
I investigated the seasonal testicular histology and acystic lobular spermatogenesis in the Western Lesser Siren, Siren intermedia nettingi, from periodic sampling of this salamander over a span of 21 yr (1994-2015) in northeastern Arkansas. My results include the following general findings: 1) the largest testicular lobules occurred primarily in January-February during spermiogenesis and spermatozoa maturation; 2) lobular regression and spermatogenic cell recrudescence were underway by late March; 3) proliferation of secondary spermatogonia in lobules was prominent in May; 4) transformation of secondary spermatogonia into primary spermatocytes occurred by mid-July, and these cells became larger in diameter through increased nuclear …
A Study Of Dental Pathology In River Otters (Lontra Canadensis) In Arkansas, C. Renn Tumlison, Jimmie Harper, Karson Grant
A Study Of Dental Pathology In River Otters (Lontra Canadensis) In Arkansas, C. Renn Tumlison, Jimmie Harper, Karson Grant
Journal of the Arkansas Academy of Science
River otters (Lontra canadensis) consume a variety of foods, including mussels, fishes, and crayfishes. These foods have hard body parts that cause wear of the teeth as the predator ages and incurs more damaging feeding experiences. This can lead to exposure of the pulp cavity and possible abscess and resorption of bone around the alveolus. Further, strong bites against harder parts of prey sometimes results in mechanical breakage, which can lead to pulpitis and severe pathology leading to tooth loss. We investigated the frequency of different forms of dental issues in a sample of 178 skulls of river …
Distal Urogenital Anatomy In The Male Wood Frog, Lithobates Sylvaticus (Anura: Ranidae), Stanley E. Trauth
Distal Urogenital Anatomy In The Male Wood Frog, Lithobates Sylvaticus (Anura: Ranidae), Stanley E. Trauth
Journal of the Arkansas Academy of Science
I investigated the microanatomy of the distal urogenital system of the male Wood Frog (Lithobates sylvaticus) from a small sample (n = 6) collected in northern Arkansas in February 2020. Specifically, my primary objectives were as follows: 1) to focus on the histology of the paired Wolffian (urogenital) ducts caudally from the kidneys to their merging with the urodeum of the cloaca, 2) to reveal the structure of the paired seminal vesicles (sperm storage structures), and 3) to compare epithelial morphologies between the distal urogenital tract and its neighboring distal alimentary tract. This information will promote a clearer …

Distal Excurrent Ducts And Penile Morphology Of The Urogenital System In The Mississippi Mud Turtle, Kinosternon Subrubrum Hippocrepis (Chelonia:Kinosternidae), Stanley E. Trauth, Michael V. Plummer
Distal Excurrent Ducts And Penile Morphology Of The Urogenital System In The Mississippi Mud Turtle, Kinosternon Subrubrum Hippocrepis (Chelonia:Kinosternidae), Stanley E. Trauth, Michael V. Plummer
Journal of the Arkansas Academy of Science
We examined the distal excurrent ductal morphology and penile anatomy of the urogenital system in the Mississippi Mud Turtle, Kinosternon subrubrum hippocrepis, from a small sample of individuals collected in Arkansas in order to provide additional information regarding turtle urogenital anatomy. Specifically, we focused on the basic anatomy and histology of distal excurrent ducts (ductus deferens and ureter), associated structures (urogenital papillae), and penile histology in this kinosternid turtle. In addition, we provide an overview of the gross urogenital anatomy in this turtle, given that little detailed information exists on this topic in the chelonian literature.

An Updated Checklist Of The Spiders (Arachnida: Araneae) Of Arkansas, Henry W. Robison, C. Renn Tumlison, Paula E. Cushing, Peggy R. Dorris
Journal of the Arkansas Academy of Science
A total of 510 species of spiders representing 43 families and 215 genera are herein reported from Arkansas. The most diverse families of state spiders were Salticidae (64 species), Lycosidae (59 species), Araneidae (55 species), and Gnaphosidae (54 species). Twelve families had only a single representative species in the state. Additional taxa will surely be added to the checklist with future taxonomic studies incorporating molecular analyses and additional collecting. This updated checklist is intended to be of use to arachnologists, researchers, naturalists, professional biologists, and managers in determining the biodiversity for Arkansas. We have worked to insure that the taxonomy …
Morphology Of Rathke’S Glands In The Alligator Snapping Turtle, Macrochelys Temminckii (Chelonia: Chelydridae), Stanley E. Trauth
Morphology Of Rathke’S Glands In The Alligator Snapping Turtle, Macrochelys Temminckii (Chelonia: Chelydridae), Stanley E. Trauth
Journal of the Arkansas Academy of Science
I examined the morphology of Rathke’s glands (RG) in the Alligator Snapping Turtle, Macrochelys temminckii, using light microscopy and scanning electron microscopy. This species possesses 4 pairs of RG (i.e., an axillary and three inframarginals) that are embedded beneath marginal bones and are named primarily according to the anatomical location of their orifices. These holocrine-type, exocrine, integumentary glands are anatomically and ultrastructurally similar to one another. Each gland contains a single and highly vascularized secretory lobule, which is bounded by a thick tunic of asymmetrically-arranged striated muscle bundles. Two types of secretory vacuoles were identified within the holocrine cells …

Distal Urogenital Anatomy Of Male Prairie Racerunners, Aspidoscelis Sexlineatus Viridis (Reptilia: Sauria: Teiidae), Stanley E. Trauth
Distal Urogenital Anatomy Of Male Prairie Racerunners, Aspidoscelis Sexlineatus Viridis (Reptilia: Sauria: Teiidae), Stanley E. Trauth
Journal of the Arkansas Academy of Science
I examined histologically the distal urogenital anatomy in male Prairie Racerunners (Aspidoscelis sexlineatus viridis) from a small seasonal sample of individuals collected in Arkansas in order to provide additional information regarding squamate urogenital anatomy. Specifically, I focused on the basic anatomy and positioning of posterior ducts and associated structures in this teiid lizard. The anatomical structures included the ductus deferens, ampulla ductus deferens, ampulla urogenital papilla (Aup), ureter, inner core tissue mass, urodaeum, and the urogenital papilla. The two Aup, which are small complimentary blind pouches representing the terminal repositories for products released by urogenital ducts, are striking …

Distal Urogenital Anatomy Of Male Southern Coal Skinks, Plestiodon Anthracinus Pluvialis (Reptilia: Scincidae), Stanley E. Trauth
Distal Urogenital Anatomy Of Male Southern Coal Skinks, Plestiodon Anthracinus Pluvialis (Reptilia: Scincidae), Stanley E. Trauth
Journal of the Arkansas Academy of Science
I investigated the morphology and histology of the distal urogenital anatomy of male southern coal skinks (Plestiodon anthracinus pluvialis) from reproductively active individuals collected in Arkansas in order to provide comparative information with recent studies on squamate urogenital anatomy. Specifically, I focused on the basic anatomy and positioning of posterior ducts in this skink, which included portions of the ductus deferens, the ampulla ductus deferentis, the sexual segment of the kidney, the ureter and collecting ducts, as well as aspects of the urodaeal chamber and urogenital papillae. I found a much reduced ampulla ductus deferentis comprising only 0.7 …
Germinal Epithelium Cytology During Spermatogenesis In The Alligator Snapping Turtle, Macrochelys Temminckii (Reptilia: Chelydridae), Stanley E. Trauth, Kevin M. Gribbins
Germinal Epithelium Cytology During Spermatogenesis In The Alligator Snapping Turtle, Macrochelys Temminckii (Reptilia: Chelydridae), Stanley E. Trauth, Kevin M. Gribbins
Journal of the Arkansas Academy of Science
We investigated the cytology of the seminiferous epithelia of the Alligator Snapping Turtle (Macrochelys temminckii). Spermatogenic and regressed testes were assessed from 2 adult individuals collected in Arkansas in May and September of 1993. Specifically, we focused on the cellular phases of germ cell development and maturation. The germ cell morphology and developmental strategy within the germinal epithelium of M. temminckii appear similar to that of other genera of turtles previously studied. Interestingly, mitotic, meiotic, and spermiogeneic cells are nearly identical to that of other turtles studied based on light microscopy. There are also 6 recognizable steps to …
