Influence Of Environmental Conditions And Inundation History On Bacterial Diversity Of Salt Marsh Soils In Southern Louisiana, Brandon M. Bagley
Influence Of Environmental Conditions And Inundation History On Bacterial Diversity Of Salt Marsh Soils In Southern Louisiana, Brandon M. Bagley
Masters Theses
Diversity patterns and controls on bacterial community composition were investigated from coastal salt marsh soils in southern Louisiana (USA) from 2012 – 2014. These salt marshes are part of an extensive coastal landscape that is experiencing land loss due to subsidence, sea-level rise, and anthropogenic activities, including from the impacts of the Deepwater Horizon oil spill in 2010. Prior to the oil spill, microbiology research focused predominately on biogeochemical roles and not on taxonomic representation in the soils or on understanding the significance of taxonomic diversity at the microbial level to marsh food webs or ecosystem dynamics. The purpose of …
The Effect Of Regular Or Reduced-Fat Distillers Grains With Solubles On Rumen Methanogenesis And The Rumen Bacterial Community, E. Castillo-Lopez, C. J. R. Jenkins, N. D. Aluthge, W. Tom, P. J. Kononoff, S. C. Fernando

Aims: The effect of feeding dried distillers grains with solubles (DDGS) or reduced-fat DDGS (RFDG) on ruminal methanogenesis and the rumen bacterial community of dairy cattle was evaluated. Methods and Results: Treatments were CONT, a diet with no distillers grains; DG, inclusion of 20% DDGS; rfDG, inclusion of 20% RFDG; and MIX, inclusion of 10% DDGS and 10% RFDG. Methane emission was measured; rumen bacterial community was evaluated by sequencing the V4 region of the 16S rRNA gene. Total methane production remained unaffected. However, feeding distillers grains tended to reduce methanogenesis per unit of feed intake, decreased the abundance of …
Genetic Sequencing Using 16s Rrna For Pathogen Identification In Retropharyngeal Lymph Nodes From Wild Elk, David J. Wilson, Jacqueline P. Kurz
Genetic Sequencing Using 16s Rrna For Pathogen Identification In Retropharyngeal Lymph Nodes From Wild Elk, David J. Wilson, Jacqueline P. Kurz
Human–Wildlife Interactions
Cervical region lymph nodes collected by hunters from 43 wild hunter-harvested elk (Cervus elaphus) in Utah were submitted to the Utah Veterinary Diagnostic Laboratory during fall 2009. We evaluated these lymph nodes as specimens for identification of bacterial pathogens using 16S rRNA genetic sequencing. Thirty-seven bacterial species were identified; each was found in 2 to 30 individual elk. Many common ruminant livestock pathogens were identified in elk; pathogens previously reported in elk were Pasteurella multocida and Streptococcus spp. Cervical region lymph nodes harvested from wild ruminants appear to be acceptable samples for genetic sequencing of bacteria.
Taxonomic Status Of A Newly Described Island Population Of The Smooth Newtlissotriton Vulgaris (Linnaeus, 1758) From Bozcaada (Çanakkale, Turkey), Nurşen Çördük, Çi̇ğdem Gül, Murat Tosunoğlu, Konstantinos Sotiropoulos
Taxonomic Status Of A Newly Described Island Population Of The Smooth Newtlissotriton Vulgaris (Linnaeus, 1758) From Bozcaada (Çanakkale, Turkey), Nurşen Çördük, Çi̇ğdem Gül, Murat Tosunoğlu, Konstantinos Sotiropoulos
Turkish Journal of Zoology
The taxonomic status and phylogenetic position of the recently recorded smooth newt (Lissotriton vulgaris) population from the island of Bozcaada (Çanakkale, Turkey) is clarified on the basis of morphological and molecular phylogenetic analyses. The L. vulgaris population from Bozcaada presents body proportions and morphological features of subsp. schmidtlerorum, such as small body length, absence of the tail filament, and dorsal crest with pointed free margin. Similarly, phylogenetic analyses of mitochondrial DNA sequences (ND4, 16S rRNA) place the Bozcaada population within Clade E of the recent L. vulgaris phylogeny, which consists of L. v. schmidtlerorum populations.
