Section 1: Effects of “Swim with the Turtles” Tourist Attractions on Green Sea Turtle (Chelonia mydas) Health in Barbados, West Indies
Kimberly Stewart, Terry Norton, Harwich Mohammed, Darren Browne, Kathleen Clements, Kirsten Thomas, Taylor Yaw, and Julia Horrocks

Section 2: Green sea turtles tend to change their diets as they age. Green sea turtles start life as omnivores in pelagic water, but once their carapace length reaches 20 to25cm they move to coastal regions; their diet, then shifts to an herbivorous diet consisting of sea grass and algae. Shortly after it was discovered that turtles were eating the waste from fisherman in Barbados during the 1990s, the “swim with turtles” tourist attractions arose. The unintentional food provision

Both groups had similar Epibiota consisting of algae and barnacles. The average white blood cell count for the SUPP group (10.2x103/µl) was slightly greater than the UNSUPP group (9.8x103/µl), but the UNSUPP group had a greater number of eosinophils. The total solids in the blood was greater in the SUPP population (4.8 g/dL) when compared to the UNSUPP group (2.9 g/dL). The packed cell volume in the SUPP group was 32.5% compared to 28% in the UNSUPP group. The analysis using the Ortho Vitros 250 showed differences in levels for everything besides carbon dioxide, amylase, low density lipoproteins, and creatinine kinase. All the differences except lipase were higher in the SUPP group, but lipase levels were higher in the UNSUPP group. The total protein, albumin: globulin ratio, albumin, alpha-2 globulins and beta globulins levels were significantly higher in the SUPP group. Five of the SUPP group had prealbumin bands as well as two from the UNSUPP group. In the vitamin panels the SUPP group was found to have higher levels of all-trans retinol, α-tocopherol, and vitamin D, and the UNSUPP group was found to possess greater amounts of lutein and zeaxanthin. The copper, phosphorus, and selenium levels were elevated in the SUPP group (Cu 0.86 ppm, P 161.5 ppm, Se 0.2 ppm) compared to the UNSUPP turtles (Cu 0.54 ppm, P 108 ppm, Se 0.08 ppm); however, the magnesium levels were decreased …show more content…
The white blood cell count ranges were outside of previously established ranges, but the mean values were within previously established ranges so the differences were deemed clinically insignificant. The total protein values were also found to be within established ranges, but based on the higher values in the SUPP group it was within reason to assume this was due to supplementation. The elevated ALT is not considered indicative for liver disease in reptiles, since it is found in hepatocytes and muscle cells, but the CK levels were not elevated so there is a chance that these turtles are in the early stages of liver disease, a biopsy would be needed to assess this. The high caloric intake coupled with the lack of foraging puts these turtles at risk of obesity and hepatic lipidosis. The increased uric acid concentrations in the blood of the SUPP turtles is likely due to the increase of proteins which increases the chance of the turtles getting gout. Increased sodium levels in the SUPP turtles were likely caused by the processed foods. The blood urea nitrogen level increase in the SUPP turtles was likely due to the high protein diet. The cholesterol and triglyceride level elevation in the SUPP group is likely due to a higher chance of having a high calorie meal before capture. In humans elevated levels increase heart disease risk, but reptile

    Lignocellulosic biomass consists of cellulose, hemicellulose, lignin, proteins, acids, salts and minerals. Chemical composition is also one of the important factors for biofuel production. Moisture content of raw pearl millet biomass was (8 %) and ash content (6.27 %) was obviously higher than that the literature report of 3.8 % (Dhabhai et al., 2012). The proximate analysis of pearl millet biomass revealed that moisture (8±0.32%), ash (6.27±0.08%), total solids (92±0.14%), water extractives (6.43±0.12), ethanol extractives (5.72±0.34), cellulose (41.6±0.16%), hemicellulose (22.32 ± 0.65), glucan (28.47±2.88%), galactan (17.24±0.46), arabinan (3.78±0.04), xylan (5.12±0.46), acid insoluble lignin (16.32±0.49) and acid soluble lignin (5.49±0.08%)…

    The average penetrations measured in the specimens were: 78.0 mm (R), 58.5 mm (L15), 50.3 mm (L30), and 34.0 mm (L60). The results show that R mortars had more capillary suction than mortars with WTS. According to Pavía and Treacy (2006), smaller the dimensions and more connected the pores, more evident are the capillary effects. The results of capillary tests show that the pores in R mortars had smaller dimension than WTS mortars and then the water suction was higher. The large pores in mortars with WTS difficult the capillary effect (Liu et al., 2011) and contributed to decrease the mechanical properties (Rovnaník, 2010).…

    If More Acid were Added, Would the Mass of the Curd Increase? Purpose The purpose of the lab was to find out if the mass of the curd would increase if more acid were to be added to the milk. Background Information The major proteins found in milk, casein and whey, are great at providing all the important amino acids. The only difference between the two is that whey is a quick digesting protein and casein is slow digesting. Whey is beneficial because it provides fast amino acids, resulting in fast protein synthesis.…

    Namely, Azulene absorbed a much higher wavelength, 576.0nm, compared to naphthalene’s absorbance of 309.3nm. This was due to differences in molecular orbitals. Naphthalene, being a benzenoid compound, had identical electron densities for its HOMO and LUMO. Azulene instead had different HOMO and LUMO. Because the orbitals in Azulene did not occupy the same location, electron-electron repulsion decreased when an electron transitions to the LUMO.…

    Nestlings from the Smelter group also showed slightly higher vitamin A levels in plasma compared to the other treatment groups, although not significantly (Table 3, Figure 3).

    For instance, my amount of vitamin, B3, B6, and C were over higher than the recommended intake. Especially, my B6 intake was 26.70 mg, but the recommended amount of B6 was 14.00 mg. Also, vitamin B6 can cause nerve toxicity although it usually doesn 't cause problems in doses lower than 300 mg per day. In this way, I should reduce meat and soy products intake. On the other hand, vitamin A, E, B2, B12, and D were lower the recommended intake. For example, vitamin D helps to prevent tooth decay.…

    From Graph 1, we can see that 5% acetic acid has the largest amount of casein precipitates, indicates that the pH value of casein is closest to 4.6. It is because addition acid adds to the milk, it will decrease the pH of casein, and neutral casein will precipitate. [1] [2] 10% acetic acid has lower amount of casein precipitates, indicates that the pH value of casein is not close to 4.6, too much acids are added and few of the casein precipitates dissolve. It is because more acid adds to the milk; it will decrease the pH of casein more, and less neutral casein will precipitate as few of casein will precipitate and dissolve again. [1] [2] 15% acetic acid has lower amount of casein precipitates, indicates that the pH value of casein is faraway to 4.6, too much acids are added and some of the casein precipitates dissolve.…

    For this experiment, the eggs were examined due to the shifting of the solution across the membrane. Which sucrose solution makes the egg gains the most weight? Lose weight? My hypothesis was that as time increased, the weight in all of the eggs would increase as well. With the eggs being soaked in different solutions, it caused me to conclude that all of the eggs would absorb some…
