Genetic Relationships Of Some Common Arkansas Freshwater Sunfishes (Centrarchidae: Lepomis) Inferred From Restriction Endonuclease Analysis Of Mitochondrial Dna, Ronald L. Johnson, K. Ashlei Williams
Genetic Relationships Of Some Common Arkansas Freshwater Sunfishes (Centrarchidae: Lepomis) Inferred From Restriction Endonuclease Analysis Of Mitochondrial Dna, Ronald L. Johnson, K. Ashlei Williams
Journal of the Arkansas Academy of Science
Geographic isolation and habitat specialization has aided in the evolution and maintenance of genetic integrity of the lepomid sunfishes (Lepomis: Centrarchidae) of North America. Our goal was to measure genetic distances between four of the eleven extant sunfish species by using mitochondrial DNA analysis. Mitochondrial DNA restriction fragment length polymorphisms (RFLPs) were examined in bluegill (L. macrochirus), redear sunfish (L. microlophus), longear sunfish (L. megalotis), and green sunfish (L. cyanellus) using 15 restriction endonucleases. The largemouth bass (Micropterus salmoides) was used as an outgroup. The phylogeny inferred from Dollo parsimony cladistic analysis largely concurred with published results from allozyme analyses …

Nesting Willow Flycatchers Discovered At Harrison, Arkansas, William C. Holimon, Douglas A. James
Journal of the Arkansas Academy of Science
The Willow Flycatcher, Empidonax traillii (Audubon), was a newly discovered species when John James Audubon found it at Arkansas Post in 1822. The bird was fairly common in summer in prairie-scrub habitat around Arkansas at least until the 1950s. There after numbers declined until one or two individuals were found occasionally at a single site in Benton County in the late 1980s through 1990s. We found a population consisting of three nesting territories on Baker Prairie Natural Area in Harrison, Boone County, Arkansas. This represents the first confirmed nesting since 1990 and only the second since 1969. A nest with …

Herpetofaunal Inventory Of Arkansas Post National Memorial, Arkansas County, Arkansas, Malcolm L. Mccallum, Stanley E. Trauth, Robert G. Neal, Vernon E. Hoffman
Journal of the Arkansas Academy of Science
The Arkansas Post National Memorial (ARPO) is a unique historical landmark with an interesting herpetofaunal community. We conducted an amphibian and reptile inventory of this national park from 2000-2002. We found eight amphibian and 21 reptilian species inhabiting the park. These included eight species not previously identified at ARPO. Overall species richness was highest at Alligator Slough, although the northern portion of ARPO was relatively rich. Aquatic trophic guilds included 7 (36.8%) piscivores, 7 (36.8%) omnivores, 4 (21.1%) insectivores, and one (5.3%) carnivore. The terrestrial trophic guilds included 13 (76.5%) insectivores, 2 (11.8%) carnivores, and 1 (5.9%) each of omnivores …

Experimental Channel Catfish Virus Infection Mimics Natural Infection Of Channel Catfish, Robin L. Stingley, Wayne L. Gray, Billy R. Griffin, Reid Landes
Journal of the Arkansas Academy of Science
Channel catfish virus (CCV) causes a severe hemorrhagic disease in channel catfish fry and fingerlings. CCV epizootics are associated with elevated water temperatures and high mortality rates. Survivors of acute disease are latently infected with i virus. In this study, we investigated conditions effecting CCV pathogenesis and latency utilizing an experimental immersion model to simulate natural infection and a population of Arkansas catfish verified to have no prior CCV exposure, the results indicate that the Auburn- 1 laboratory strain is comparable to CCV field isolates in virulence and ability to establish latent infection. The study confirms that water temperature and …
