A Study Of Dental Pathology In River Otters (Lontra Canadensis) In Arkansas, C. Renn Tumlison, Jimmie Harper, Karson Grant Jan 2022

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 …


An Updated Checklist Of The Spiders (Arachnida: Araneae) Of Arkansas, Henry W. Robison, C. Renn Tumlison, Paula E. Cushing, Peggy R. Dorris Jan 2021

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 …
