Occurrence Of Blarina Brevicauda In Arkansas And Notes On The Distribution Of Blarina Carolinensis And Cryptotis Parva, R. S. Pfau, D. Blake Sasse, M. B. Connior, I. F. Guenther
Journal of the Arkansas Academy of Science
We provide an update on the species and distribution of shrews occurring in Arkansas. Shrews were collected within Arkansas Game and Fish Commission Wildlife Management Areas and along the Buffalo National River. We also searched mammal collections at several institutional museums to provide additional locality records for Cryptotis parva. Specimens of Blarina were identified to species by DNA sequencing of the mitochondrial cytochrome b gene. Previously, Blarina hylophaga was believed to occur in the northwest corner of Arkansas and B. carolinensis throughout the rest of the state. However, our genetic analysis revealed that it is B. brevicauda that occupies the …

Seasonal Activity, Population Characteristics, And Age Estimation In The Aquatic Salamander, Siren Intermedia Nettingi (Goin), J. A. Sawyer, S. E. Trauth
Journal of the Arkansas Academy of Science
We conducted a study of the Western Lesser Siren (Siren intermedia nettinigi), at a locality termed the Airport Road site in Jonesboro (Craighead County, AR) from November 2004 until March 2007. This site consisted of a network of roadside ditches in cultivated lawns in an industrial park. Even though sirens are known to occur frequently in ditches, most studies of the genus Siren have taken place in natural wetlands. We compiled mark-recapture data at the Airport Road site for each season to determine if the seasonal activity pattern for sirens in northeast Arkansas varied from activity data previously published from …

Summary Of Previous And New Records Of The Arkansas Darter (Etheostoma Cragini) In Arkansas, B. K. Wagner, M. D. Kottmyer, M. E. Slay
Journal of the Arkansas Academy of Science
The Arkansas Darter, Etheostoma cragini, has an extremely limited distribution in Arkansas and is designated as a candidate for listing under the federal Endangered Species Act. It was first documented in the state in 1979 in Wilson Spring near Fayetteville. Between 1979 and 1985 it was collected in 4 additional headwater streams in Benton and Washington counties. A 1997 study documented the persistence of the species in 3 of the 5 historic streams, but 1 stream yielded only a single individual. A 2004-2005 study reassessed the status of the 5 historically known populations and searched broadly for new populations, documenting …

The Efficacy Of Thermal Imaging Technology For Documenting American Woodcock On Pine Stands, A. Long, A. Locher
The Efficacy Of Thermal Imaging Technology For Documenting American Woodcock On Pine Stands, A. Long, A. Locher
Journal of the Arkansas Academy of Science
Thermal imaging technology provides a useful tool to understand nocturnal activity of wildlife. We used thermal imaging to document American woodcock use of pine stands in Arkansas. A thermal imaging camera was used along logging roads on sampling dates ranging from December 2009 – February 2010 and in February 2011. We located 4 woodcock in 2010 in 20.27 hours of sampling within all stand types. For 11.55 h we only sampled pine seedling/clearcut stands due to vegetation structure inhibiting our ability to identify woodcock with the camera. In 2011 we found 2 woodcock in 7.42 hours of sampling on pine …

Status And Distribution Of The Gapped Ringed Crayfish, Orconectes Neglectus Chaenodactylus, In Arkansas, Brian K. Wagner, C. A. Taylor, Mark D. Kottmyer
Journal of the Arkansas Academy of Science
Orconectes neglectus chaenodactylus, the gapped ringed crayfish, is an uncommon and poorly-known, stream-dwelling crayfish that is endemic to the central White River basin of Arkansas and Missouri. This study surveyed a semi-random selection of stream sites in the Arkansas portion of this range in order to characterize the crayfish communities and evaluate the status of O. n. chaenodactylus in Arkansas. Collections of a total of 1,107 individual crayfish specimens were made at 45 sites, including 497 O. n. chaenodactylus from 21 sites. Orconectes punctimanus was the crayfish species most commonly associated with O. n. chaenodactylus, occurring at 71% of sites …
Population Status Of The Southern Cavefish, Typhlichthys Subterraneus In Arkansas, A. Romero, M. S. Connor, G. L. Vaughan
Population Status Of The Southern Cavefish, Typhlichthys Subterraneus In Arkansas, A. Romero, M. S. Connor, G. L. Vaughan
Journal of the Arkansas Academy of Science
We summarize the results of our study on the status of the southern cavefish (Typhlichthys subterraneus) in Arkansas. Its presence in the state represents the western-southern limits of its distribution. Four localities have been confirmed that contain individuals of this species: Richardson Cave (Fulton County), Alexander Cave/Clark Spring (Stone County), Ennis Cave (Stone County), and Lake Norfork (Baxter County). A fifth locality has been cited as a well in Randolph County, but because the exact location is unknown, its presence has not been confirmed. A number of unconfirmed localities for “cavefishes” in the region has not been included in this …

Cargo Of Birds To Arkansas, The Hurricanes In 2008 And The Swept Clean Hypothesis, Douglas A. James, Kimberly G. Smith, Joseph C. Neal, John G. Hehr
Journal of the Arkansas Academy of Science
Three hurricanes in the hurricane season of 2008 brought to Arkansas several unusual marine and other birds from southerly locations. There were 10 species noted, totaling 44 individual birds. Sooty Terns, numbering 15, were the most numerous. Laughing Gulls were next in abundance. In the mix of birds there was only 1 new species for the state, a Least Grebe. The hurricanes brought vastly different cargos of birds, and two hypotheses relating to how hurricanes transport birds are proposed. The findings supported the "swept clean" hypothesis over the "blown through" hypothesis.
Distribution Of The Southeastern Shrew (Sorex Longirostris Longirostris) In Arkansas, G. A. Mikel, Gary A. Heidt, David W. Clark
Distribution Of The Southeastern Shrew (Sorex Longirostris Longirostris) In Arkansas, G. A. Mikel, Gary A. Heidt, David W. Clark
Journal of the Arkansas Academy of Science
The southeastern shrew (Sorex longirostris longirostris) is considered uncommon and, due to a lack of knowledge, a Species of Greatest Conservation Need in Arkansas. Also, eastern Arkansas may represent a gap in the species’ distribution. Therefore, we evaluated persistence at previous capture sites, surveyed additional counties, quantified microhabitat at our capture locations, and compiled occurrences. Since Sealander and Heidt’s (1990) Arkansas Mammals detailed its occurrence, additional captures by Huston and Nelson (1994), Showen (2006), and this study document new counties (Pope and Searcy) and a new ecoregion (Arkansas Valley). Number of specimens in Arkansas has increased to 17 in 11 …

Seasonal Activity Of The Ozark Highlands Leech, Macrobdella Diplotertia, (Annelida: Hirudinea) In North-Central Arkansas, M. Connior, Stanley E. Trauth
Journal of the Arkansas Academy of Science
The Ozark Highlands Leech, Macrobdella diplotertia, occurs intermittently throughout Arkansas, Kansas, and Missouri. Limited natural history of this species is known. Herein, we report a new county occurrence for this leech from a cattle pond in southern Marion County, Arkansas. We also report on the seasonal activity and novel hosts of this species. We surveyed the inhabited pond monthly to determine activity and collected natural history data on this species. This study indicated that this species appears to be most active in spring, summer, and early fall, but inactive during the winter. We also documented five new anuran hosts for …

Condition Relative To Phenotype For Bass Populations In Southern Arkansas Lakes, R. Allen, C. Cato, Colton Dennis, Ronald L. Johnson
Condition Relative To Phenotype For Bass Populations In Southern Arkansas Lakes, R. Allen, C. Cato, Colton Dennis, Ronald L. Johnson
Journal of the Arkansas Academy of Science
Southern Arkansas reservoir largemouth bass populations (Micropterus salmoides) are often supplemented with stocks of Florida bass (M. floridanus) in an attempt to boost the frequency of hybrid and trophy bass. Stocking rates of Florida bass among these lakes are highly variable. We determined bass phenotype composition among 12 lake populations based upon stocking protocols: exclusively Florida bass, primarily Florida bass, mixed stocking protocol and primarily largemouth bass. We also compared condition among phenotypes (n =2,100) to test for hybrid or phenotype vigor. Mean relative weight of bass for most lakes but SWEPCO Lake (mean Wr = 72) were ≥ 90. …

Temporal Changes Of Largemouth Bass Alleles In A Northern Arkansas Reservoir Stocked With Florida Bass, R. Allen, Ronald L. Johnson
Journal of the Arkansas Academy of Science
Southwest Electric Power Company (SWEPCO) Lake in northwest Arkansas is a thermal cooling pond for the Flint Creek Power Station. This reservoir has been regularly stocked with Florida bass (Micropterus floridanus) on top of a pre-existent largemouth bass (M. salmoides) population since its creation in 1976. Allozyme analysis of diagnostic loci in 1995-1996 revealed that 62% of the alleles were Florida bass alleles and that most fish were FX hybrids (77%). Microsatellite analysis of diagnostic loci in 2006 revealed that 78% of the alleles were Florida bass alleles and that most fish were FX-Florida hybrid bass (59%), with the remainder …

Qualitative Freshwater Mussel Survey Of The South Fork Spring River, Missouri And Arkansas, H. C. Martin, John L. Harris, Alan D. Christian
Journal of the Arkansas Academy of Science
A qualitative freshwater mussel survey was performed in the South Fork Spring River, Arkansas between May 13 and June 20, 2006 to assess community composition, density, and the presence of endangered mussel species (Family Unionidae). Twenty-one species from 460 individuals of mussels were collected using qualitative methods. Of those 21 species, 11 were ranked as S1, S2, or S3 using rankings established by the Arkansas Natural Heritage Commission Heritage Program. Three species, Amblema plicata (Say 1817), Lampsilis reeveiana (Call 1887), and Ptychobranchus occidentalis (Conrad 1836), comprised 48% of all mussels collected with 12%, 15%, and 21%, respectively. Mussel abundance within …

Determination Of Benthic Soil Conditions Using Nematodes: Nematode Foodweb Conditions Of Fish Ponds In The Lincoln And Desha Counties Of Arkansas, M. M. Matute, P. W. Perschbacher, A. Newell
Journal of the Arkansas Academy of Science
We determined the health status of similar channel catfish (Ictalurus punctatus) ponds in Lincoln and Desha counties of Arkansas, using the nematode soil food web condition as our reference point. Soil nematodes were categorized into colonizer-persister (cp) groups, based on their life course characteristics e.g sensitivity to environmental changes, body size, etc. These cp groups represent different components of the soil food web, which in turn were indicators of soil conditions. Benthic soil samples were collected at four week intervals over a 4-month period, from 6-ponds in each county. The nematodes were extracted according to standard methods and the recovered …

Distribution And Population Characteristics Of Lower Walleye In The Eleven Point River, Arkansas, Ronald L. Johnson, S. D. Henry, Sam W. Barkley
Journal of the Arkansas Academy of Science
Walleye Sander vitreus (Mitchill) distributions and ecology have been poorly studied in southern river basins. We studied the longitudinal distribution and population characteristics of walleye in an unregulated river within the Ozark region of the U.S., the lower Eleven Point River, Arkansas, which has high species diversity. Walleye were collected in a 60 km segment of the river by daytime boat electrofishing over a three year period (2002-2004). Catch rates, growth rates and size structure were high relative to other streams studied in North America. Catch per effort ( = 5.2/h) was similar seasonally, spatially and among years. Proportional stock …

Journal of the Arkansas Academy of Science
We analyzed stream inventories, phylogeographic studies, community and population estimates, life history and reproductive biology research, and suitable habitat investigations conducted from 1997-2008, as well as the Arkansas Natural Heritage Commission mussel database, to update the conservation status for all native freshwater unionoid bivalves thought to occur in Arkansas. Prior to this study, Harris et al. (1997) reviewed the distribution and status of 75 freshwater mussels considered native to Arkansas and ranked 22 species as endangered, threatened or special concern. We now recognize 85 mussel taxa in Arkansas; however, some of those have yet to be described or their nomenclature …
