Turkish Journal of Zoology
The concentration of metals and effects of these metals on hematological parameters were examined in avian species by using feathers and blood samples collected from different sites of Sialkot. The major reason for significant differences in hematological parameters and concentrations of metal contents between different species was the difference in feeding habitat. Metal concentrations in feathers and blood samples indicated that the chromium and lead were not found at a safe level. The results did not revealed a significant negative association between metal contents and hematological parameters but concluded that increased metal contents exert negative effects on hematological status especially …
Androgenic Hormones In Crustacean Aquaculture: A Review, Muzaffer Mustafa Harlioğlu, Ardavan Farhadi̇
Androgenic Hormones In Crustacean Aquaculture: A Review, Muzaffer Mustafa Harlioğlu, Ardavan Farhadi̇
Turkish Journal of Zoology
Increased demands of the seafood market have led to the rapid growth in crustacean aquaculture production in various parts of the world. Therefore, an expansion in the knowledge of the reproductive biology of crustaceans has become more important. Hormones released from the androgenic gland (AG) in crustaceans are liable for both the separation of primary and secondary sexual features and reproductive behavior. AG removal in male crustaceans causes a transformation of the intersex animals towards the females and a degeneration of spermatids and reproductive organs. AG implantation and injection of AG extracts are common approaches for crustacean masculinization. In this …

Impact Of Natural Cheese Composition On Proteolysis And Its Effects On Process Cheese Functionality, Natasha Scherber
Impact Of Natural Cheese Composition On Proteolysis And Its Effects On Process Cheese Functionality, Natasha Scherber
Electronic Theses and Dissertations
Cheddar cheese is a commodity and a top-selling cheese in the United States. Enhanced flavors of cheddar cheese requires aging, which will allow proteolysis increase. Proteolysis is the most complex process that happens in cheese manufacturing and can be difficult to control because of environmental factors and compositional characteristics. The ripening process, which is the most timely and costly procedure in cheese manufacturing, can also be unpredictable when aspects, such as cheese composition, are changed. The coagulant is responsible for the first stage in proteolysis, which will produce large peptides. Small peptides are subsequentially produced during the second stage by …
A Post-Pneumonia Epizootic Evaluation Of The Rapid City, South Dakota Bighorn Sheep Herd, Amanda N. Ensrud
A Post-Pneumonia Epizootic Evaluation Of The Rapid City, South Dakota Bighorn Sheep Herd, Amanda N. Ensrud
Electronic Theses and Dissertations
Pneumonia is a major factor affecting populations of free-ranging bighorn sheep (Ovis canadensis) across western North America. Pneumonia can occur in large-scale epizootics, during which greater than half of the population typically dies. After these epizootics, surviving ewes continue to conceive and bear lambs. However, lamb recruitment may remain low due to periodic or annual pneumonia outbreaks causing high lamb mortality rates, sometimes greater than 90%. Our study focused on the Rapid City, South Dakota bighorn sheep (BHS) herd that has recorded pneumonia-induced population decline since 2009. The first objective was to improve lamb health and survival by identifying and …
Post-Fledging Habitat Selection And Movements Of Juvenile Mallards In The Prairie Pothole Region, Cynthia E. Anchor
Post-Fledging Habitat Selection And Movements Of Juvenile Mallards In The Prairie Pothole Region, Cynthia E. Anchor
Electronic Theses and Dissertations
The Prairie Pothole Region (PPR) of North America provides critical habitat for waterfowl across life stages, but anthropogenic changes to the landscape have negatively impacted habitat quality for waterfowl. The mallard (Anas platyrhynchos) is abundant and socioeconomically valuable in the PPR, as it is a preferred target species of waterfowl hunters. Extensive research has evaluated breeding ecology of mallards in the PPR, but the period between juvenile mallards fledging and migrating has rarely been studied. The post-fledging ecology of juvenile mallards is a vital consideration for comprehensive waterfowl management. Further, juvenile mallards are a significant portion of hunter harvest at …

Genetic And Morphological Assessment Of Pigtoe Mussels (Unionidae: Pleurobemini: Fusconaia/Pleurobema Spp.) In Ozark Drainages, Logan Tyler Phelps
Online Theses and Dissertations
North America is home to nearly 300 species of native freshwater mussels. Many species within this group are in need of conservation efforts and for these efforts to be effective, species delimitations must be as accurate as possible. Intraspecific variation and interspecific convergence are sources of confusion within morphology-based taxonomy, particularly within the Pleurobemini. Molecular phylogenetic work has revealed multiple problems within currently accepted Pleurobemini classifications. Specifically, Fusconaia has been shown to harbor cryptic diversity within drainages of the Ozarks. Further, Pleurobema rubrum and P. sintoxia have been shown to be possible conspecifics despite have differing shell morphologies. This study …
Design And Validation Of Artificial Feeders To Study Feeding Preferences And Growth Of Hematophagous Juvenile Sea Lamprey (Petromyzon Marinus), Gracie Li-Ting-Wai
Design And Validation Of Artificial Feeders To Study Feeding Preferences And Growth Of Hematophagous Juvenile Sea Lamprey (Petromyzon Marinus), Gracie Li-Ting-Wai
Theses and Dissertations (Comprehensive)
The parasitic and invasive land-locked sea lamprey Petromyzon marinus populations contributed to the collapse of the Great Lakes fisheries in the mid-1900s, while native anadromous populations are currently under threat and require conservation efforts for protection. Despite the increasing concern for both populations of this species, the juvenile stage of the sea lamprey’s life cycle has not been well studied. This is due, in part, to ethical concerns raised around holding live host fish with juveniles and the lack of an alternative feeding method to maintain these juveniles in the laboratory. The feeder should be designed to minimize fouling of …
The Role Of The Skin Microbiome In Amphibian Pathogen Susceptibility In Turnbull National Wildlife Refuge, Krista S. Dodd
The Role Of The Skin Microbiome In Amphibian Pathogen Susceptibility In Turnbull National Wildlife Refuge, Krista S. Dodd
EWU Masters Thesis Collection
The fungal pathogen, Batrachochytrium dendrobatidis (Bd), has led to the decline and extinction of many amphibian populations, but some bacteria in the skin microbiome can inhibit its growth. In Turnbull National Wildlife Refuge (TNWR) in eastern Washington, Bd is highly prevalent, but the role of the skin microbiome in Bd infection dynamics have not been examined in this region. We hypothesized that frogs with lower Bd infection intensities would have higher skin bacterial diversity and more abundant anti-Bd bacteria, indicative of a more protective function. Our study combined cultureindependent and culture-dependent methods to assess the relationship between Bd and the …

Increased efficiency of nutrient utilization can potentially be gained with increased starch digestion in the small intestine in ruminants. However, ruminants have quantitative limits in the extent of starch disappearance in the small intestine. The objective is to explore the nutritional and physiological constraints that contribute to limitations of carbohydrate assimilation in the ruminant small intestine. Altered digesta composition and passage rate in the small intestine, insufficient pancreatic α-amylase and/or small intestinal carbohydrase activity, and reduced glucose absorption could all be potentially limiting factors of intestinal starch assimilation. The absence of intestinal sucrase activity in ruminants may be related to …

Fisheries Research Reports
In July 2021, the Department of Primary Industries and Regional Development convened an ecological risk assessment (ERA) of the fisheries that access the State-wide Small Pelagic Scalefish Resource. The ERA considered the potential ecological impacts of the West Coast Purse Seine Fishery, South Coast Purse Seine Fishery, Purse Seine Development Zones and the recreational fishers who catch small pelagic scalefish. The assessment evaluated the impact of each fishing sector/method on all relevant retained and bycatch species, endangered, threatened and protected species, habitats and the broader environment.
