..., with faster turnover during the summer, when they are lighter and have high daily energy expenditure. However, the preference for glucose as a substrate for fatty acid synthesis over fructose does not change seasonally. Hummingbirds Sugar metabolism Stable isotope analysis Lipogenesis Fat turnover...

..., the fish exposed to the fishmeal diet were subjected to the same experimental conditions as the fish on the other diets, including the same tank sizes, filtration systems, water temperature and chemical parameters, light:dark cycle and feeding regime. For the stable isotope analysis, fin clips...

...Sora Lee Kim; Carlos Martínez del Rio; Dave Casper; Paul L. Koch SUMMARY Stable isotope analysis has provided insight into the dietary and habitat patterns of many birds, mammals and teleost fish. A crucial biological parameter to interpret field stable isotope data is tissue incorporation rate...
