The Effects Of Infliximab On The Fibrosis Response Of Three-Spine Stickleback, Mita Kale
The Effects Of Infliximab On The Fibrosis Response Of Three-Spine Stickleback, Mita Kale
Honors Scholar Theses
This study was conducted to determine if the monoclonal antibody drug infliximab could effectively suppress the fibrosis immune response in three-spine stickleback fish. Successful suppression of this response could allow for further study of cestode infection and growth without the presence of fibrosis. Infliximab’s efficacy was investigated through conducting two intraperitoneal injection experiments and examinations of the fibrosis in the body cavity of the euthanized stickleback. We used immune adjuvant alum to induce a fibrosis response without the presence of the S. solidus tapeworm parasite. Ultimately, the differences in fibrosis levels between the treatment groups that received alum and the …
Stoichiometry And Parasitism: Changes In Nutrient Concentrations In The Three-Spined Stickleback-Schistocephalus Solidus System, Megan Braat
Honors Scholar Theses
Ecological stoichiometry is a rapidly growing field of study that assesses the elemental composition of organisms in ecosystems and the impact that changes in these elemental compositions have on populations. Parasitism is widely studied for its role in altering the physiology and behavior of hosts within a population. However, the interaction between parasitism and the stoichiometry of the host-parasite system has not been well-established. To determine the impact of parasitism on stoichiometry of host, we measured the elemental composition (%C, %N, and %P) and ratios (C:N, C:P, and N:P) of a population of parasitized and unparasitized Gasterosteus aculeatus (three-spined stickleback) …
Seasonal Plumage Condition Variation And The Thermal Value Of The Feather Coats Of House Sparrows (Passer Domesticus), Jordana Mf Graveley, Margaret Rubega, Kevin R. Burgio
Seasonal Plumage Condition Variation And The Thermal Value Of The Feather Coats Of House Sparrows (Passer Domesticus), Jordana Mf Graveley, Margaret Rubega, Kevin R. Burgio
Honors Scholar Theses
Feathers are critical to how birds thermoregulate, and thus their total energy balance. The feather coat insulates birds by trapping air next to the skin and acting as a physical barrier to heat loss. Despite previous work studying thermal balance in birds, relatively few studies have focused on the thermal contribution of the feather coat alone; most studies have focused on physiological and behavioral responses. Moreover, to our knowledge, no studies have directly measured the effect of feather wear through the annual cycle on the thermal performance of the feather coat. To address this, we used a thermal camera to …
