Survey Of Medium And Large Mammals In An Urban Park (Murray Park), Little Rock, Pulaski County, Arkansas, Josie H. Dickins, David W. Clark, Steffany C. White, Gary A. Heidt
Journal of the Arkansas Academy of Science
Because of increased environmental awareness by city planning commissions, there are more urban parks and greenbelt areas. These areas often result in increased human and wildlife contacts, thus resulting in the need for management plans regarding urban wildlife. From September 1998 to March 1999, we conducted mammal surveys of the urban greenspace Murray Park, Little Rock, Pulaski County, Arkansas. Surveys were conducted using five methods: direct observations; spot lighting; live trapping; animal sign; and scent posts. Species recorded included, opossum (Didelphis virginiana), nine-banded armadillo (Dasypus novemcinctus), fox squirrel (Sciurus niger), gray squirrel (Sciurus carolinensis), beaver (Castor canadensis), woodchuck (Marmota monax), …

Post-Metomorphic Growth And Reproduction In The Eastern Narrowmouth Toad (Gastrophryne Carolinensis) From Northeastern Arkansas, Stanley E. Trauth, Walter E. Meshaka Jr., Robert L. Cox Jr.
Journal of the Arkansas Academy of Science
Post-metamorphic growth and the reproductive cycle of the eastern narrowmouth toad (Gastrophryne carolinensis) were studied from 204 individuals collected during the April August 1989 activity season in a two-county area of northeastern Arkansas near the northwestern edge of the species' geographic range. Late summer metamorphs require a full growing season before they can reproduce as they approach their second year of life. The oldest individuals may be at least five years old. By late April, gonadal cycles of adults had commenced; the males were producing sperm, and some of the females were gravid. Fertility of both sexes increased during the …
Revised List Of Arkansas Terrestrial Mollusks With Notes On The Geographic Distribution Of Species, Brian F. Coles, Gerald E. Walsh
Revised List Of Arkansas Terrestrial Mollusks With Notes On The Geographic Distribution Of Species, Brian F. Coles, Gerald E. Walsh
Journal of the Arkansas Academy of Science
A revised list of of Arkansas terrestrial mollusks is presented, based on the authors' collections, incorporating data from the scientific literature and taking into account recent changes in taxonomy and species concepts. 144 species are recorded for Arkansas, of which 127 represent the autochthonous fauna of the state. The biogeographical position of Arkansas is reflected in its land mollusks, i.e., approximately 40% of Arkansas species are also widely distributed in the United States east of the Rocky Mountains, 12% are more widely distributed to the north, 11% are typical of the Gulf Coastal Plain, 14% form a "Mid Western" assemblage …

Occurrence And Reproduction Of The Alabama Shad, Alosa Alabamae Jordan And Evermann, In The Ouachita River System Of Arkansas, Thomas M. Buchanan, Josh Nichols, Don Turman, Colton Dennis, Stuart Woolridge, Brett Hobbs
Journal of the Arkansas Academy of Science
The anadromous Alabama shad, Alosa alabamae, has drastically declined in abundance in recent decades throughout its historic range and has previously been reported in Arkansas from only five localities. Three of those locality records are pre- 1900. Sampling by seine in the Ouachita River drainage system of southern Arkansas in July and August of 1997 and 1998 produced more than 300 juvenile A. alabamae from two localities on the Little Missouri River and four localities on the Ouachita River. One record of an adult Alabama shad, taken on 4 April1997 by an angler below Remmel Dam on the Ouachita River, …

Clinostomum Marginatum (Yellow Grub) Metacercaris In Black Bass From The Caddo River In West Arkansas, James J. Daly Jr., H. Michael Matthews, Randal J. Keller, James J. Daly
Journal of the Arkansas Academy of Science
Seventy-two bass (Micropterus-spp.), mostly smallmouth, were collected from three areas of the Caddo River in west Arkansas and examined for the presence of Clinostomum marginatum metacercariae. Prevalence, mean abundance, and abundance for all fish were 68%, and 4.2 ±6.5, and 30, respectively. Fish from the upstream area near the headwaters were more heavily infested than those from further downstream. A gill/total body larval ratio of seven, was found for bass from another Arkansas stream, was examined as a predictor for total Clinostomum populations instream bass. Using the formula gill parasites X seven divided by N(72), a value of 3.3 was …
Arkansas Gray Fox Fur Price-Harvest Model Revisited, Peta Elsken-Lacy, Amy M. Wilson, Gary A. Heidt, James H. Peck
Arkansas Gray Fox Fur Price-Harvest Model Revisited, Peta Elsken-Lacy, Amy M. Wilson, Gary A. Heidt, James H. Peck
Journal of the Arkansas Academy of Science
Peck and Heidt (1985) proposed a linear model that demonstrated that for gray fox (Urocyon cinereoargenteus) in Arkansas; total fur harvests from 1966-1982 were highly correlated with mean pelt values. Single variable models using linear regression analysis of current season pelt values (CSPV) and previous season pelt values (PSPV) were designed to predict total fur harvests. These models demonstrated high correlations (r =0.93 and 0.89, respectively). In the past 15 years, markets for fur have undergone many perturbations within Arkansas and overseas resulting in great changes in mean pelt prices. In an attempt to evaluate the continued performance of the …
Effects Of Predation On Two Species Of Stream-Dwelling Crayfish (Orconectes Marchandi And Cambarus Hubbsi) In Pool And Riffle Microhabitats, Heidi Dukat, Daniel D. Magoulick
Effects Of Predation On Two Species Of Stream-Dwelling Crayfish (Orconectes Marchandi And Cambarus Hubbsi) In Pool And Riffle Microhabitats, Heidi Dukat, Daniel D. Magoulick
Journal of the Arkansas Academy of Science
Community structure may be governed by many abiotic and biotic factors. Of the biotic factors, predation is often considered to be critical in structuring freshwater stream communities. In the Warm Fork of the Spring River, the crayfish Cambarus hubbsi is found mainly in riffles, whereas the crayfish Orconectes marchandi is found in high numbers in pools. We hypothesized that predation, mainly by fish, is a factor causing this segregation. Higher predation rates for C. hubbsi than 0. marchandi in the pools and higher predation rates for 0. marchandi than C. hubbsi in the riffles were expected. A transplant tethering experiment …

Survey Of Diseases In Wild Turkeys In Arkansas, Wayne E. Thogmartin, James E. Johnson, Bradley A. Schaeffer, Camille C. Ciriano
Journal of the Arkansas Academy of Science
Nineteen dead wild turkeys were necropsied and 573 live wild turkeys were physically examined for pathological agents in Arkansas between 1992 and 1997 to determine the proximate role disease may play in declining wild populations in Arkansas. Necropsy of the dead wild turkeys identified avian pox and histomoniasis as the most common diseases (16% and 11% of necropsies, respectively). Avian pox was recorded from three major physiographic regions in the state (Ozark Highlands, Ouachita Mountains, Gulf Coastal Plain). One hen died of non-accidental crop impaction, the fifth occurrence observed in the southeastern United States. Another hen died after developing severe, …
Status Of Three Plethodontid Salamanders (Genus Plethodon) From The Ouachita National Forest Of Southwest Arkansas, Stanley E. Trauth, J. D. Wilhide
Status Of Three Plethodontid Salamanders (Genus Plethodon) From The Ouachita National Forest Of Southwest Arkansas, Stanley E. Trauth, J. D. Wilhide
Journal of the Arkansas Academy of Science
A three-year field investigation was initiated in 1996 to update previous information on the local abundance and distribution of three salamanders of the genus Plethodon (P. caddoensis, P.fourchensis, and P. ouachitae); these salamanders are found within a five-county area of the Ouachita National Forest in southwestern Arkansas. Plethodon fourchensis was most numerous at three sites in Polk County; a total of 18 specimens was found. Searching for Plethodon fourchensis was successful following moderate-to-heavy precipitation but only in selected habitats on Fourche and Irons Forks mountains. The preferred habitats of P. caddoensis were talus-covered slopes and wet ravines consisting of mostly …
