A recent theoretical model used to predict hatchling sex of reptiles with temperature‐dependent sex determination predicts that sex ratios will be fairly robust to moderate global warming as long as eggs experience substantial daily cyclic fluctuations in incubation temperatures. Expand
Depth and temperature of the blue marlin, Makaira nigricans, observed by acoustic telemetry
Monitoring of the depth, swimming speeds, body temperature and water temperature preference of six blue marlin near the Hawaiian islands in July and August 1989 found an initial rise in body temperature was associated with the anaerobic muscle activity during capture and is an indication of the physiological stress involved in capture. Expand
Direct measurement of swimming speeds and depth of blue marlin
Measurements of swimming speed show that, while blue marlin are capable of high speeds, they spend most of their time swimming slowly, indicating that many large aquatic vertebrates swim slowly to minimize energetic costs of transport. Expand
Experimental demonstration of the energetic cost of parasitism in free-ranging hosts
The results demonstrate that even classically ‘benign’ parasites such as feather lice can reduce host condition through the accumulation of subtle energetic costs over time, and argues that experimental manipulations are a prerequisite for documenting such effects. Expand
The influence of incubation temperature on post-hatching fitness characteristics of turtles
Results clearly indicate that incubation temperature can have an important influence on hatchling fitness by influencing post-hatch mortality (sea turtles) and growth rates (freshwater turtles). Expand
Temperature variation within and between nests of the green sea turtle, Chelonia mydas (Chelonia: Cheloniidae) on Heron Island, Great Barrier Reef
Nest temperature profile data indicated that the 1998–99 nesting season on Heron Island would have produced a strongly female-biased sex ratio amongst hatchlings. Expand
Sun exposure, nest temperature and loggerhead turtle hatchlings: Implications for beach shading management strategies at sea turtle rookeries
The viability of natural shading options, such as the planting of trees behind nesting beaches, for combating the adverse effect of increased nest temperature caused by increased air temperatures is explored. Expand
Incubation temperature, energy expenditure and hatchling size in the green turtle (Chelonia mydas), a species with temperature-sensitive sex determination
The total amount of energy consumed during incubation, and hatchling dimensions, were similar at both temperatures, but hatchlings from 26 degreesC had larger mass, larger yolk-free mass and smaller residual yolks than Hatchlings from 30 degreesC, because of the difference in mass of hatchlings.
