Parental Investment, Embryo Growth, and Hatchling Lipid Reserves in Softshell Turtles (apalone Mutica) from Arkansas
The smooth softshell Apalone mutica is a North American trionychid turtle typically found in moderate to fast moving rivers and streams. Such habitats contrast with more resource rich environments (e.g., marshes and swamps) inhabited by other turtle species for which parental investment and egg and hatchling components have been studied. We measured components of eggs, embryos, and hatchlings a...
متن کاملBehavioral responses of hatchling painted turtles (Chrysemys picta ) and snapping turtles (Chelydra serpentina ) at subzero temperatures
We monitored behavioral responses of cold-acclimated hatchling painted turtles (Chrysemys picta ) indigenous to Nebraska and hatchling snapping turtles (Chelydra serpentina ) indigenous to Nebraska and Arkansas during cooling (0.18C/min) to temperatures as low as ÿ198C. All turtles made exploratory movements during cooling and locomotion occurred at temperatures as low as ÿ2 to ÿ48C, but C. pic...
متن کاملFeeding Behaviour and Feeding Motorics in Subadult European Pond Turtles, Emys orbicularis (Linnaeus, 1758)
The European Pond Turtle is a predominantly aquatic species, generally assumed to feed exclusively under water by using hydrodynamic mechanisms. We analysed the kinematics of the aquatic food uptake and food transport by using high-speed videos with 500 fps. The analyses revealed that subadult E. orbicularis use compensatory suction for food uptake, but the food transport is performed by a comb...
متن کاملMeasuring Energy Expenditure in Sub-Adult and Hatchling Sea Turtles via Accelerometry
Measuring the metabolic of sea turtles is fundamental to understanding their ecology yet the presently available methods are limited. Accelerometry is a relatively new technique for estimating metabolic rate that has shown promise with a number of species but its utility with air-breathing divers is not yet established. The present study undertakes laboratory experiments to investigate whether ...
متن کاملIncubation temperature affects the immune function of hatchling soft-shelled turtles, Pelodiscus sinensis
Identifying how developmental temperature affects the immune system is critical for understanding how ectothermic animals defend against pathogens and their fitness in the changing world. However, reptiles have received little attention regarding this issue. We incubated eggs at three ecologically relevant temperatures to determine how incubation temperature affects the immune function of hatch...
