Gut Microbiota Of Migratory Passerines At Stopover, 2015 University of Southern Mississippi
Gut Microbiota Of Migratory Passerines At Stopover, William Bagley Lewis
Although the gut microbiota provides many beneficial functions to animal hosts, relatively little is known about the gut microbiota of passerines. It is likely that gut microbes are especially important during the migratory phase; however gut atrophy experienced during prolonged migratory flight may cause disruptions of the stable microbiota. Fecal samples were collected from several species of passerine after crossing the Gulf of Mexico during spring migration and before crossing during fall, and microbiota communities were analyzed using next-generation sequencing. Despite showing large inter-individual variation, a core microbiota composed largely of Firmicutes and Proteobacteria was identified in all birds. Microbiota ...
Are Large Dogs Smarter Than Small Dogs? Investigating Within Species Differences In Large And Small Dogs: Spatial Memory, 2015 University of Southern Mississippi
Are Large Dogs Smarter Than Small Dogs? Investigating Within Species Differences In Large And Small Dogs: Spatial Memory, Megan S. Broadway
The study of canine cognition can be useful in understanding the ontology and selective pressures that affect the development of cognitive abilities. Dogs have undergone intensive artificial selection yielding distinctive breeds which differ both phenotypically and behaviorally. Breed based cognitive differences have not been found but some studies suggest there may be differences in broader categories such as working disposition and sex. The influence of size on canine cognition has not been thoroughly addressed despite the fact that large dogs are often perceived to be ‘smarter’ than small dogs. This preconception has only recently been addressed and supported in one ...

An Analysis Of The Characteristics And Practices Of Selected Alabama Small Livestock Producers: A Focus On Economics And Marketing, Jannette R. Bartlett, Nii O. Tackie, Mst Nusrat Jahan, Akua Adu-Gyamfi
Professional Agricultural Workers Journal
The study examined the characteristics and practices of small livestock producers, focusing on economics and marketing. Data were obtained from a convenience sample of 121 small producers from several South Central Alabama counties, and were analyzed using descriptive statistics, including chi-square tests. The socioeconomic characteristics reflected a higher proportion of part-time farmers; a higher proportion with at most a two-year/technical degree or some college education; and a higher proportion with $40,000 or less annual household income. A majority had been farming more than thirty years, and most had small herds. Also, very few made profits; many sold ...
Spreading Holiday Spirit And Northwestern Salamanders, Ambystoma Gracile (Baird 1859) (Caudata: Ambystomatidae), Across The Usa, Michael R. Rochford, Jeffrey M. Lemm, Kenneth Krysko, Louis A. Somma, Robert W. Hansen, Frank J. Mazzotti
Papers in Herpetology
Introduced species of amphibians and reptiles are of growing conservation concern (Bury and Luckenbach 1976; Krysko et al. 2011; Meshaka 2011). Unintentional introductions result largely from individuals escaping from enclosures or hitch-hiking in cargo or on vehicles, whereas intentional introductions occur primarily because a species is perceived to be of value to humans or from deliberately releasing sick or unwanted animals, including pets (Kraus 2009; Krysko et al. 2011). In Florida, most known introductions are directly related to the pet trade, but about 12% are related to the cargo pathway (Krysko et al. 2011). In this paper, we report the ...
Current Status Of The Northern Long-Eared Myotis (Myotis Septentrionalis) In Northwestern Nebraska, 2015 University of Nebraska—Kearney
Current Status Of The Northern Long-Eared Myotis (Myotis Septentrionalis) In Northwestern Nebraska, Keith Geluso, Patricia Freeman, Cliff Lemen
Transactions of the Nebraska Academy of Sciences and Affiliated Societies
The Northern Long-eared Myotis (Myotis septentrionalis; Order: Chiroptera) occurs in eastern, southern, and northern Nebraska, but its current distribution in northwestern parts of the state is unclear due to its recent arrival to the region. We investigated the status of this species in the Pine Ridge via mist net (2011-2014) and acoustic surveys (2014). We documented nine species of bats in the region, including M. septentrionalis. Of 423 total bats, M. septentrionalis was represented by four individuals, the fewest of all species during our four-year survey. We only documented M. septentrionalis in Sheridan County; this county is where the species ...
High Prevalence Of Leucocytozoon Parasites In Nestling Northern Goshawks (Accipiter Gentilis) In The Northern Great Basin, U.S.A., Michelle I. Jeffries, Robert A. Miller, Michelle D. Laskowski, Jay D. Carlisle
The Northern Goshawk (Accipiter gentilis) is currently listed as a sensitive species by the U.S.D.A. Forest Service. Previous research in our study area, the South Hills of the Minidoka Ranger District of the Sawtooth National Forest, Idaho, identified possible signs of parasite infections among the banded adult and nestling goshawks, which could influence their survival and breeding success. Therefore, we sought to quantify the prevalence and intensity of Leucocytozoon parasites among a sample of nestling goshawks in the South Hills during the 2012 breeding season. We sampled 27 nestlings from 12 nests for Leucocytozoon parasites by examining ...

The Story Behind The Hog Breeding Herd Revision: When Is A Breeding Animal Not A Breeding Animal?, Seth D. Meyer
Iowa Ag Review
The March 1, 1995, Hogs and Pigs report showed a significant re,risionof iowa's December 1, 1994, breeding herd inventory figures. The breeding herd inventory was revised up 100,000 head to 1.5 million from the initial release of the December 1, 1994, inventory report. This decreased the previously calculated liquidation by one-third, with breeding herd inventory falling 12 percent from Sep1ember 1, 1994, to December 1, 1994, ralher than 18 percent. With a revision in the breeding herd of 100,000 head in Iowa, the question becomes, did the USDA estimation procedure miss the real story of ...
Taxonomy Of The Bitentaculate Cirratulidae (Polychaeta), 2015 University of Massachusetts Boston
Taxonomy Of The Bitentaculate Cirratulidae (Polychaeta), Stacy A. Tewari
Graduate Masters Theses
The bitentaculate cirratulid polychaetes are an important faunal element of both near shore and deep-sea benthic faunal communities. The true diversity of the family is currently unknown due to a large number of undescribed species and erroneously applied “cospmopolitan” names being applied to local species. Cirratulids have been misidentified even in the local waters near the University of Massachusetts Boston. The current study presents six new species from North America. Caulleriella venefica, Chaetozone anasimus, Chaetozone diodonta, and Chaetozone hystricosus are described from Boston Harbor and Massachusetts Bay where only two species had previously been reported. Aphelochaeta bullata and A. guttata ...

It finds the literature insufficient to explain the lack of such blooms.
Effect Of Aging Time And Retail Displaying Period With A Short-Term Temperature Abuse On Color Stability Of Two Beef Muscles, Derico Setyabrata, Hyun-Wook Kim, Yuan H. Brad Kim
The Summer Undergraduate Research Fellowship (SURF) Symposium
Meat color and tenderness are two most important quality factors affecting consumers’ decision on meat purchasing. Post-mortem meat aging has been widely practiced to improve palatability attributes, but could be adversely related to meat color. In particular, temperature abuse during aging or retail display can negatively affect the color stability of aged meat. The objective of this study was to determine the effect of aging time and short-term temperature abuse during display on color stability of two beef muscles (M. longissimus dorsi, LD and semitendinosus, ST). LD and ST muscles were separated from three beef carcasses, vacuum-packaged and assigned into ...
Phytogenic Feed Additives As An Alternative To Antibiotic Growth Promoters In Broiler Chickens, 2015 Iowa State University
Phytogenic Feed Additives As An Alternative To Antibiotic Growth Promoters In Broiler Chickens, G. R. Murugesan, Basharat Syed, Sudipto Haldar, Chasity Pender
G. R. Murugesan
The recent trend toward reduction of antibiotic growth promoters (AGP) in North American poultry diets has put tremendous pressure on the industry to look for viable alternatives. In this context, phytogenic feed additives (PFA) are researched to improve gut health and thereby performance. An experiment was conducted with the objective to evaluate the effects of PFA as an alternative to AGP on small intestinal histomorphology, cecal microbiota composition, nutrient digestibility, and growth performance in broiler chickens. A total of 432, day-old Vencobb 400 broiler chicks were randomly assigned to one of three dietary groups, each consisting of 12 replicate pens ...

Beef Cattle Management Systems For Estrus Synchronization And Heifer Development, Hazy Rae Nielson
Theses and Dissertations in Animal Science
Four experiments were conducted to evaluate estrus synchronization and heifer development systems. In the first experiment delaying AI 19 h following GnRH administration in a hybrid estrus detection and time AI protocol was evaluated. Final pregnancy rate was not different among heifers detected in estrus, AI at the time GnRH administration, or delayed AI. The second study compared the effect of melengestrol acetate (MGA) -PG and 14-d controlled internal drug release (CIDR) -PG estrus synchronization protocols on estrus response and pregnancy rates of 311 d old heifers. Final pregnancy rate was similar between CIDR and MGA treatment groups. The objective ...
Dietary Strategies For Mitigation Of Methane Production By Growing And Finishing Cattle, 2015 University of Nebraska-Lincoln
Dietary Strategies For Mitigation Of Methane Production By Growing And Finishing Cattle, Anna C. Pesta
Theses and Dissertations in Animal Science
Interest in reducing methane (CH4) emissions by cattle has increased recently. Loss of feed energy as CH4 represents both an environmental concern and an energetic loss to the animal. Manipulation of dietary composition has proven to be an effective mitigation strategy. Experiments were conducted to evaluate the effect of several dietary characteristics on CH4 production in growing and finishing cattle, and to develop a novel, non-invasive method for quantifying emissions from animals in a production setting. Short-term gaseous emissions of CH4 and carbon dioxide (CO2) were measured and the CH4:CO2 was used ...
Habitat Use By Spruce Grouse In A Fragmented System, 2015 Northern Michigan University
Habitat Use By Spruce Grouse In A Fragmented System, Laurel A. Hill
All NMU Master's Theses
The spruce grouse is a boreal obligate species that has been protected in Michigan since 1915 (Ammann 1963). Despite protection, the status of spruce grouse is uncertain in Michigan and other parts of the Midwest, and there have been few attempts at large-scale surveys or monitoring (Williamson et al. 2008). I studied a population of spruce grouse near the southern edge of their range on the Yellow Dog Plains in Marquette County, Michigan.
I investigated fecal pellet counts as a possible method to assess spruce grouse presence and habitat use. My results validated the use of fecal pellet occurrence as ...
