Articles in this issue explore various actions taken in response to different crises: lessons about the environment from the COVID-19 pandemic; how seafood sellers in the CT and Southeast Asia responded to the challenges of the pandemic; how the challenges of rising seas and developed coasts are being dealt with through managed retreat, buyouts and other actions in NC and CT; and research on the long-term effects of the Deepwater Horizon oil spill on dolphins led by CTSG Director Sylvain De Guise.
The Effects Of Poor Maternal Nutrition During Gestation On Colostrum And Milk Quality And Immunoglobulin G Concentrations In Sheep, Alexandra Bettencourt
The Effects Of Poor Maternal Nutrition During Gestation On Colostrum And Milk Quality And Immunoglobulin G Concentrations In Sheep, Alexandra Bettencourt
Honors Scholar Theses
Maternal over- and under-nutrition have negative effects on the growth and development of offspring. Colostrum and milk are critical to neonatal development, and composition and quality of colostrum and milk may be influenced by maternal factors, including diet. In this study, 46 pregnant ewes received one of three diets, 60% (RES), 100% (CON), or 140% (OVER) of National Research Council (NRC) nutrition requirements for total digestible nutrients from d 30 of gestation until parturition. Colostrum samples were collected within 24 hours of parturition. Milk samples were collected on d 3 and d 21 postpartum. Total solid concentrations of samples were …
Effects Of Probiotic Supplementation On Growth And Health Of Pre-Weaned Dairy Calves, Lily Bello
Effects Of Probiotic Supplementation On Growth And Health Of Pre-Weaned Dairy Calves, Lily Bello
Honors Scholar Theses
Dairy calf immune development leaves calves susceptible to illness during the pre-weaned stage of life. Previous studies have shown that the use of probiotics during this time may result in increased growth rates and decreased incidence of illness, particularly diarrhea and scours. We hypothesized that by providing probiotics during the time from birth until weaning, calves on study would experience similar growth and health benefits. Neonatal calves (N=32) were provided milk replacer three times daily, with half of the calves receiving Probios® supplements mixed in with their first morning feeding. Growth and health measurements were collected weekly. Probiotic administration significantly …
Using Citizen Science To Determine The Age Of Alewife Fish, Rodchill-Paul Jules
Using Citizen Science To Determine The Age Of Alewife Fish, Rodchill-Paul Jules
Honors Scholar Theses
Aging scales of economically important fish like the Alewife (Alosa pseudoharengus) is a critical task in the fisheries industry, which can benefit from the help that citizen science offers. In order for those benefits to take effect, common people should be comfortable and fairly knowledgeable about what is expected of them in the study. Then, results can be generated in a way that gives all types of citizens a good opportunity to participate and produces reliable data that can be used for scientific purposes. This experiment studied the effects of simple word instructions versus diagramed instructions on the …

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 …
