Examination Of The Cell Wall Of Micrasterias Radiosa Var Radiosa (Conjugatophyceae) By Transmission And Scanning Electron Microscopy, Jennifer A. Akin, Richard L. Meyer
Journal of the Arkansas Academy of Science
The cell wall of Micrasterias radiosa var. radiosa Ralfs 1848 (Conjugatophyceae) was examined by transmission and scanning electron microscopy. Previous electron microscopy of this taxon has not been performed; thus these are new observations. The cell wall was recognized to be of the Cosmarium type with complex pores external to the plasma membrane that penetrate the secondary wall and with ornamentation arising from the secondary wall. Subdivided regions of the pore apparatus, the pore head, pore bulb, connecting pore channel, and pore depression were detected. Pores of type 4 were located in the isthmal region and at the division of …

No comprehensive investigation of WRNWR aquatic macroinvertebrates had been conducted previously. Thirty sampling stations were established within WRNWR. Each station was sampled twice, providing 60 totalsamples, for 1.5 man hours witha Turtox Indestructible™ dip net. Three black light trap samples were taken to augment the species list. A total of 15,056 individuials representing 219 taxa was taken by dip net samples during the sampling period October 1989-September 1990. Insects comprised …
New Distributional Records For Freshwater Mussels In The Ouachita River, Arkansas, William R. Posey Ii, John L. Harris, George L. Harp
New Distributional Records For Freshwater Mussels In The Ouachita River, Arkansas, William R. Posey Ii, John L. Harris, George L. Harp
Journal of the Arkansas Academy of Science
Two freshwater mussel species thought to have been extirpated from Arkansas have recently been rediscovered in the Ouachita River in the vicinity of Camden. Prior to this survey, Wheeler (1918) last reported Arkansia wheeleri Ortmann and Walker, the Ouachita rock-pocketbook, and Cumberlandia monodonta (Say), the spectaclecase, from the Ouachita River near Arkadelphia. Quadrula apiculata (Lea), the southern mapleleaf, has been reported from Arkansas on two occasions, but due to taxonomic uncertainty, it has not been recognized in recent compilations of Arkansas freshwater mussels. During this survey, the southern mapleleaf was collected from the Ouachita River which verifies its occurrence within …

First Arkansas Records For Bigscale Logperch Percina Macrolepida Stevenson (Pisces: Percidae), With Comments On Habitat Preference And Distinctive Characters, Thomas M. Buchanan, Chad Hargrave, Drew Wilson, L. G. Claybrook, Philip W. Penny Jr.
Journal of the Arkansas Academy of Science
Fish samples were collected with seines and rotenone from 21 localities representing five major habitat types along the Red River in Arkansas. The bigscale logperch, Percina macrolepida, was found at 11 of those sites, providing the first records ofthat species from the state. The primary preferred habitat parameters for bigscale logperch are no current, a sand and/or silt substrate, and a water depth of 1.0-2.0 m. Percina macrolepida is morphologically very similar to the widespread and common logperch, P. caprodes, but can be distinguished from all forms of that species in Arkansas by a combination of characters. Snout shape and …

Distribution Of Baird's Pocket Gopher (Geomys Breviceps) In Arkansas; With Additional County Records, Douglas A. Elrod, Gary A. Heidt, Mark R. Ingraham, Earl G. Zimmerman
Journal of the Arkansas Academy of Science
Recently, a population of pocket gophers in the north-central portion of Arkansas was determined to be the plains pocket gopher (Geomys Imrsarius), rather than Baird's pocket gopher (Geomys breviceps). This changed the known range of both species extensively. A detailed examination of the known range of Baird's pocket gophers (G. breviceps) in Arkansas resulted in 12 new county records. Biogeographically, G. breviceps appears to be found in all physiographic regions within the state with the possible exception ofCrowley's ridge. It is most common in the Gulf Coastal Plain and rarest in the Mississippi Alluvial Plain. The distribution ofG. breviceps is …

Techniques For Radiotracking And Biotelemetry Of Coolwater Sport Fish In Norfork Reservoir, Arkansas, Kenda S. Flores
Journal of the Arkansas Academy of Science
Sonic and radio transmitters were implanted in 19 fish in Norfork Reservoir (12 walleye and seven striped bass) to determine the better transmitter type for two coolwater fish species in riverine and deep basin habitats. Radio transmit ters were equipped with either internal or external antennas and both radio and sonic transmitters had thermistors. Sonic transmitters proved superior to radio transmitters forlocating tagged fish after stratification. Fish implanted with radk transmitters were not found after July while fish implanted with sonic transmitters were located 87% of the time. Walleyt remained in the spring-fed riverine portion ofthe reservoir where water temperatures …

Biogeography Of Arkansas Mammals With Notes On Species Of Questionable Status, Gary A. Heidt, Douglas A. Elrod, V. Rick Mcdaniel
Journal of the Arkansas Academy of Science
Seventy-one native or re-introduced species of mammals were analyzed with respect to their geographical distributions and relationships to the four broad physiographical regions of Arkansas. Mammalian diversity in the Ozark Mountains, Ouachita Mountains/ Arkansas River Valley, Gulf Coastal Plain, and Mississippi Alluvial Plain/Crowley's Ridge was not area dependent. The majority of mammalian species (44) occurs statewide with the greatest diversity in the interior highland regions. The Ozark Mountains contain the most species endemic to an area. Thirteen species which are of questionable status in Arkansas are discussed. The presence of the plains pocket gopher (Geomys bursarius), a second species of …
Application Of A Modified Ziehl-Neelsen's Carbol-Fuchsin Stain For Observing Nuclei In Vegetative Hyphae Of The Puffball Species Lycoperdon Pyriforme, Martin J. Huss
Journal of the Arkansas Academy of Science
Nuclei of vegetative hyphae of the puffball species Lycoperdon pyriforme are small and difficult to stain. A simple mitotic staining technique utilizing a modified version of Ziehl-Neelsen's carbol-fuchsin stain, originally developed for examining bacteria and small chromosomes of plants, has proven useful for observing fungal nuclei in this gasteromycete species. Cells of vegetative hyphae were pre-treated for 2 hours with an aqueous solution saturated with naphthalene, fixed in a 3:1 mixture of 100% ethanol and glacial acetic acid, and hydrolyzed for 10 minutes in a 1:1 mixture of 100% ethanol and 12 M hydrochloric acid. Cells were rinsed with distilled …
