Myxomycetes Of Big Bend National Park, Texas, Lois H. Tiffany, George Knaphus
Journal of the Iowa Academy of Science: JIAS
Seventy species of Myxomycetes have been collected directly in the field or observed later in the laboratory from field materials in moist chambers from Big Bend National Park, Texas. Collections were made over a 10 year period, 1989-1997 and 1999, during intensive seven-day fungus collecting trips to Big Bend in late September each year. McGraw (1968) in an earlier study of Texas Myxomycetes had reported 28 species from Big Bend, some of which were also found in this study. A total of 81 species are reported from the park. A variety of environmental conditions occurred during the 10 years with …

Effects Of Recording Media On Echolocation Data From Broadband Bat Detectors, Ethan P. White, S. D. Gehrt
Effects Of Recording Media On Echolocation Data From Broadband Bat Detectors, Ethan P. White, S. D. Gehrt
Biology Faculty Publications
Bat detectors are an important tool for ecological studies of bats. However, the quality and quantity of data may be affected by the recording devices used to record the output from the detector. We compared recordings of bat activity from audiocassette recorders and computers. Numbers of calls/hour, passes/hour, identifiable passes/hour, and feeding buzzes/hour were similar (all P’s > 0.1) between recording devices. All call characteristics, except for the minimum frequency and characteristic frequency, differed (P < 0.05) between tapes and computers. Species identification with discriminate function analysis was less reliable with tape data than with computer data, particularly when the model built with computer-recorded reference calls was tested with tape-recorded calls. Therefore, we suggest when tape recorders are used for field recording that they also are used to record reference calls.

Department of Animal Science: Faculty Publications
Reproductive performance is a major concern for pork producers because the financial stability of a pork enterprise that produces piglets is substantially influenced by fecundity index (FI) for number of piglets born alive (FI = farrowing rate x litter size born alive). It is well known that farrowing rate and litter size are affected by numerous factors. A new reproductive technique that pork producers are hearing and reading about is intra-uterine insemination. Intra-uterine insemination is the process of placing spermatozoa directly into the uterine body instead of the cervix as traditionally done. The uterine body is located between the cervix …
Effect Of Animal Grouping On Feeding Behavior And Intake Of Dairy Cattle, R. J. Grant, J. L. Albright
Effect Of Animal Grouping On Feeding Behavior And Intake Of Dairy Cattle, R. J. Grant, J. L. Albright
Department of Animal Science: Faculty Publications
Although data are scarce, it is clear that grouping strategy can have a significant impact on the feeding behavior and feed intake of dairy cattle. Feed intake is controlled by ruminoreticular fill and physiological mechanisms, but grouping is a component of the cow’s feeding environment that can modulate intake as a result of its impact on cow comfort, competition for feed and other resources, and herd health. Social dominance and competition for feed impact feeding behavior and proper grouping strategy will minimize the negative impact of excessive competition on intake and enhance beneficial effects of group feeding such as social …

Our observations of bovine follicles indicated that the original histological classifications of atresia were inaccurate. A detailed histological, ultrastructural and immunohistochemical study of antral follicles from bovine ovaries collected from an abattoir and from animals whose large follicles had been monitored by ultrasonography was conducted to investigate this further. Nidogen and CD68 were immunolocalized to observe the follicular basal lamina and macrophages, respectively. In randomly collected ovaries, approximately one quarter of all antral follicles were undergoing antral atresia, as designated in this study. Antral atresia was characterized by early destruction of the layers of the membrana granulosa closest to the …

Analysis of the genetic variation of an endangered population is an important component for the success of conservation. Animals from two local Romanian pig breeds, the Mangalitsa and Bazna, were analyzed for variation at a number of genetic loci using PCR-based DNA tests. Polymorphism was assessed at loci which 1) are known to cause phenotypic variation, 2) are potentially involved in trait differences or 3) are putative candidate genes. The traits considered are disease resistance, growth, coat color, meat quality and prolificacy. Even though the populations are small and the markers are limited to specific genes, we found significant differences …
Nutritional Methods To Decrease N Losses From Open-Dirt Feedlots In Nebraska, Galen Erickson, Terry Klopfenstein
Nutritional Methods To Decrease N Losses From Open-Dirt Feedlots In Nebraska, Galen Erickson, Terry Klopfenstein
Department of Animal Science: Faculty Publications
Nitrogen losses from cattle feedlots are a concern due to loss of valuable N and enrichment of the atmospheric N pool. Nutritional methods to decrease losses would have economic and environmental benefit. One method to decrease N losses is by increasing carbon on the pen surface. From a management perspective, feeding a diet that will increase carbon may be the most cost effective. Therefore, three experiments evaluated feeding corn bran (less digestible than corn) at either 0, 15, or 30% of the diet. The 15 and 30% bran diets increase organic matter (carbon) excretion by approximately 0.5 and 1.0 kg/steer/d, …

Molecular Cloning Of An \Alpha-Amylase Gene From Bacillus Subtilis Rskk246 And Its Expression In Escherichia Coli And In Bacillus Subtilis, Numan Özcan, Adem Altinalan, Mehmet Sai̇t Eki̇nci̇
Turkish Journal of Veterinary & Animal Sciences
Bacillus subtilis RSKK246 was found to produce approximately a 65-kDa \alpha-amylase enzyme. A gene was isolated encoding \alpha-amylase activity that corresponded to this size and was inserted into pUC18 plasmid which was transferred to Escherichia coli. An approximately 1.7kbp fragment, which contains a whole \alpha-amylase gene, was excised and inserted into pUB110 and then transferred into the different B. subtilis strains including RSKK246, RSKK243, RSKK244, YB886 and ORBAM. The a-amylase gene was cloned into the plasmids and expressed with its own promoter, and this promoter sequence seemed to function in the E. coli and in all B. subtilis strains. Specific …
