The Role Of Microbiota On Campylobacter Jejuni Colonization And Growth Performance In Broiler Chickens, Ayidh Almansour Aug 2022

The Role Of Microbiota On Campylobacter Jejuni Colonization And Growth Performance In Broiler Chickens, Ayidh Almansour

Graduate Theses and Dissertations

The successful poultry production at modern era comes from the vertical integratedindustrialization, which has fundamentally changed how animals have been living for millions of years. Antimicrobial growth promoters have been used to sustain the efficient industrialized animal production, driving antimicrobial overuse and resistance. Because of the increasing pressure from consumer’s concerns and government regulations, it is urgent to develop antimicrobial free alternatives as growth promoters in poultry production, but few effective antimicrobial alternatives are currently available. Campylobacter jejuni is one of the worldwide prevalent foodborne bacterial pathogens mainly transmitted from poultry. However, few mechanisms are available on why C. jejuni …


Northern Elephant Seal (Mirounga Angustirostris) Colony Establishment And Growth In The King Range National Conservation Area, California, Emma Hatton Levy Jan 2022

Northern Elephant Seal (Mirounga Angustirostris) Colony Establishment And Growth In The King Range National Conservation Area, California, Emma Hatton Levy

Cal Poly Humboldt theses and projects

The King Range colony is the northernmost successful and expanding breeding site for northern elephant seals (Mirounga angustirostris). To evaluate the composition and growth of this colony, I conducted systematic surveys recording counts, age classes, births, and resighting seals with individually identifiable flipper tags. The timing of life-history events (breeding, molting, and resting) of all elephant seal sex and age groups at the King Range was consistent with observations at other colonies. Colony counts during breeding and molting have increased steadily over the 4-year study period (2018-2021), and pup production has increased by 87% since the first year …


Community Interventions To The Food Insecurity Crisis Inuit Currently Face In Nunangat, Alyssia R. Getschow Jan 2022

Community Interventions To The Food Insecurity Crisis Inuit Currently Face In Nunangat, Alyssia R. Getschow

Honors Theses

Inuit living in Nunangat, a northern territory in Canada, are facing unprecedented rates of food insecurity. The increasing impacts of anthropogenic climate change are rapidly changing the Arctic landscape in Nunangat, posing challenges to Inuit hunters who hunt and live completely self-sufficient off of the land. This lack of access to country foods and the impacts these conditions are having on Inuit communities are forcing Inuit to consider aid propositions from the Canadian government. Due to a long history of conflict with white settlers during the colonization of Canada, there is a feeling of distrust and cultural distaste between Canada …
