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 …

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 …

Age-Dependent Cranial Variations In Mesocricetus Brandti (Mammalia: Rodentia) Distributed In Turkey, Nuri̇ Yi̇ği̇t
Turkish Journal of Zoology
Animals were assigned to four age groups according to molar wear, field notes and external and cranial measurements. Six days-old animals were referred to newborn, up to 30 days as young and thereafter as adult; animals with very worn molars were considered old. In addition to the statistical differences among age groups, it was determined that the main morphological differences were in the interorbital constriction, the shape of the braincase, the ridges and the position of occipital condyles. While the incisors and the first molars erupted in seven days-old animals, the second and third molars begun to erupt after seven …

Dna Sequence Of Melanocortin 1-Receptor Gene In Coturnix Japonica: Correlation With Three E Locus Alleles—E,E+, And Erh, Rupali Ugrankar, Kim Cheng, Ronald Okimoto
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
The melanocortin 1-receptor (MC1-R) gene plays a key role in the expression of fur and feather color in mammals and birds by regulating the distribution of two melanin pigments: eumelanin (black/brown) and pheomelanin (red/yellow). MC1-R corresponds to the classical Extension (E) locus in mice, pigs, dogs, horses, and chickens. Three E locus alleles, the wild-type (e+), brown (E), and redhead (erh) have been identified in Japanese quail (Coturnix japonica). To determine if the quail E locus phenotypes were due to variation in the MC1-R gene, the coding region of the MC1-R gene was PCR amplified and DNA sequenced using genomic …

Application Of Gene Transfer Technology For Genetic Improvement Of Fish, Ali̇ye Sarmaşik
Application Of Gene Transfer Technology For Genetic Improvement Of Fish, Ali̇ye Sarmaşik
Turkish Journal of Zoology
The worldwide decline of natural fish stocks, the accumulation of chemical pollutants in aquatic environments and increasing world consumption of fish products has provided an impetus in many countries for a rapid growth in aquaculture. Fish produced from aquaculture currently account for over one-fourth of fish consumed by humans. However, success in aquaculture mainly depends on breeding, feeding and protection from disease. Application of recombinant DNA technology in aquaculture can help to improve these requirements.
