Intense selective pressures applied over short evolutionary time have resulted in homogeneity within, but substantial variation among, horse breeds. Utilizing this population structure, 744 individuals from 33 breeds, and a 54,000 SNP genotyping array, breed-specific targets of selection were identified using an F_ST-based statistic calculated in 500-kb windows across the genome. A 5.5-Mb region of ECA18, in which the myostatin (MSTN) gene was centered, contained the highest signature of selection in both the Paint and Quarter Horse. Gene sequencing and histological analysis of gluteal muscle biopsies showed a promoter variant and intronic SNP of MSTN were …

Horses were domesticated from the Eurasian steppes 5,000–6,000 years ago. Since then, the use of horses for transportation, warfare, and agriculture, as well as selection for desired traits and fitness, has resulted in diverse populations distributed across the world, many of which have become or are in the process of becoming formally organized into closed, breeding populations (breeds). This report describes the use of a genome-wide set of autosomal SNPs and 814 horses from 36 breeds to provide the first detailed description of equine breed diversity. F_ST calculations, parsimony, and distance analysis demonstrated relationships among the breeds that largely …

Mutation From Arginine To Lysine At The Position 189 Of Hemagglutinin Contributes To The Antigenic Drift In H3n2 Swine Influenza Viruses, Jianqiang Ye, Yifei Xu, Jillian Harris, Hailiang Sun, Andrew S. Bowman, Fred L. Cunningham, Carol Cardona, Kyoungjin J. Yoon, Richard D. Slemons, Xiu-Feng Wan

USDA Wildlife Services: Staff Publications

Two distinct antigenic clusters were previously identified among the H3N2 swine influenza A viruses (IAVs) and were designated H3N2SIV-alpha and H3N2SIV-beta (Feng et al., 2013. Journal of Virology 87(13), 7655–7667). A consistent mutation was observed at the position 189 of hemagglutinin (R189K) between H3N2SIV-alpha and H3N2SIV-beta fair isolates. To evaluate the contribution of R189K mutation to the antigenic drift from H3N2SIV-alpha to H3N2SIV-beta, four reassortant viruses with189R or189K were generated. The antigenic cartography demonstrated that the R189K mutation in the hemagglutinin of H3N2IAV contributed to the antigenicdrift, separating these viruses into H3N2SIV-alpha to H3N2SIV- beta. This R189K mutation was also …

Biodiversity, Biogeography, And Conservation Of Bats In The Lesser Antilles, Scott C. Pedersen, Hugh H. Genoways, Gary G. Kwiecinski, Peter A. Larsen, Roxanne J. Larsen

University of Nebraska State Museum: Mammalogy Papers

The chiropteran fauna of the Lesser Antilles consists of 27 species. The diversity of this fauna is low when compared with Neotropical faunas of large continental islands or at sites on the adjacent mainland, however, the Lesser Antillean fauna contains 11 species endemic to these islands making it worthy of large-scale conservation efforts. At the southern end of the Lesser Antilles, the biological limit of the Lesser Antillean bat fauna is marked by Koopman’s Line. To the south of this line, the bat faunas of the Grenadines and Grenada are composed of South American and widespread species of bats. The …

Chemical Defense Of An Asian Snake Reflects Local Availability Of Toxic Prey And Hatchling Diet, D. A. Hutchinson, A. H. Savitzky, G. M. Burghardt, C. Nguyen, J. Meinwald, F. C. Schroeder, A. Mori

Biological Sciences Faculty Publications

Species that sequester toxins from prey for their own defense against predators may exhibit population-level variation in their chemical arsenal that reflects the availability of chemically defended prey in their habitat. Rhabdophis tigrinus is an Asian snake that possesses defensive glands in the skin of its neck (nuchal glands'), which typically contain toxic bufadienolide steroids that the snakes sequester from consumed toads. In this study, we compared the chemistry of the nuchal gland fluid of R.tigrinus from toad-rich and toad-free islands in Japan and determined the effect of diet on the nuchal gland constituents. Our findings demonstrate that captive-hatched juveniles …

A New Species Of Metathelazia (Nematoda: Pneumospiruridae) From The Lungs Of A Nine-Banded Armadillo In Central Mexico = Especie Nueva De Metathelazia (Nematoda: Pneumospiruridae) De Los Pulmones De Un Armadillo Del Centro De México, F. Agustín Jiménez-Ruiz, Rogelio Rosas-Valdez, Scott Lyell Gardner

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

Twenty-four worms were collected from the bronchioles in both lungs of a male nine-banded armadillo Dasypus novemcinctus Linnaeus, 1758 captured in Teacalco, Morelos, Mexico. The worms, herein named Metathelazia mexicana n. sp., show a constriction in the esophagus at the level of the nerve ring; males of the species have 7 pairs of papillae, fewer than the other species in the genus. Metathelazia capsulata is the most similar species to Metathelazia mexicana; however, the latter has much shorter spicules. This is the fourth species in the genus known to occur in the New World.

On The Morphology And Taxonomy Of Griphobilharzia Amoena Platt And Blair, 1991 (Schistosomatoidea), A Dioecious Digenetic Trematode Parasite Of The Freshwater Crocodile, Crocodylus Johnstoni, In Australia [Critical Comment], Thomas R. Platt, Eric P. Hoberg, Leslie A. Chisholm

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

Griphobilharzia amoena Platt and Blair, 1991 was originally described was originally described as a dioecious trematode, parasitic in the circulatory system of the Australian freshwater crocodile, Crocodylus johnstoni, with the female completely enclosed in a gynecophoric chamber of the male and the two worms orientated anti-parallel to each other. A recent publication questions the original description, arguing that G. amoena is monoecious and, as a consequence, the species was transferred to Vasotrema Stunkard, 1928 (Spirorchiidae) as Vasotrema amoena n. comb. We provide photomicrographic evidence that the original description of G. amoena is correct and that Griphobilharzia Platt and Blair, …
