Phenotypic Effects of Thermal Means and Variances on Smooth Softshell Turtle (apalone Mutica) Embryos and Hatchlings
Temperature is a crucial factor in the development of oviparous organisms. Under natural conditions, the eggs of many species are subjected to changing thermal environments, but most laboratory studies have incubated eggs at constant temperatures. To evaluate the phenotypic effects of different thermal means and variances and to separate temperature effects from maternal effects, eggs from 10 c...
متن کاملApalone ferox – Florida Softshell Turtle
Species Recognition. — The Florida softshell, Apalone ferox, is the largest of the three softshell turtle species found in Florida and has the darkest coloration. It is also the only softshell species found throughout the length of the peninsula. Adults are large to very large (up to 43.6 kg and 73.6 cm carapace length), flat, brown turtles with a cartilaginous shell that is covered by skin rat...
متن کاملResidual yolk energetics and postnatal shell growth in Smooth Softshell Turtles, Apalone mutica.
We examined functions of residual yolk (RY) in hatchling Smooth Softshell Turtles (Apalone mutica). Removal of RY did not affect survival, shell growth, or resting metabolic rates of turtles for 40 d after hatching. Our estimates of metabolic rate suggest that RY can fuel maintenance and activity metabolism for approximately 25 days. A. mutica absorb more than 1g of water in the first 2 weeks o...
متن کاملParental 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 کاملSexual differentiation in the spiny softshell turtle (Apalone spinifera), a species with genetic sex determination.
It is hypothesized on the basis of sex determination theory that species exhibiting genetic sex determination (GSD) may undergo sexual differentiation earlier in development than species with environmental sex determination (ESD). Most turtle species exhibit a form of ESD known as temperature-dependent sex determination (TSD), and in such species the chronology of sex differentiation is well st...
