Influence of Moisture, Temperature, and Substrate on Snapping Turtle Eggs and Embryos
Flexible-shelled eggs of common snapping turtles (Chelydra serpentina) were incubated on two substrates (sand and vermiculite) at each of three temperatures (26.0°, 28.5°, 31.0°C) and three moistureExpand

Hydric Conditions During Incubation Influence Locomotor Performance of Hatchling Snapping Turtles
Locomotor performance of hatchling snapping turtles ( Chelydra serpentina ) was assessed while turtles were running on land and swimming in water. Hatchlings from eggs incubated on a relatively wetExpand

Analysis of the nest environment of tuatara Sphenodon punctatus
Water potential and temperature were monitored in 20 natural nests of tuatara, Sphenodon punctatus, through 12 months of incubation on Stephens Island, New Zealand. Tuatara nest in rookeries in openExpand

Influence of the hybric and thermal environments on eggs and hatchlings of painted turtles (Chrysemys picta)
Eggs of painted turtles (Chrysemys picta) were incubated at temperatures of 22.0, 27.0, and 32.0 C on substrates with water potentials of -150, -300, and -1100 kPa using a 3 x 3 factorial design. TheExpand

Water-vapor conductance of testudinian and crocodilian eggs (class reptilia).
Flexible-shelled eggs of snapping turtles (Chelydra serpentina) have conductances to water vapor that are 55 times higher than predicted for avian eggs of similar size, whereas rigid-shelled eggs ofExpand

This chapter explores the evolution of the Amniote. The Amniote egg presumably evolved from anamniote egg that gave rise via direct development to fully formed, precocial young. The precursor egg,Expand

Calcium mobilization, water balance, and growth in embryos of the agamid lizard Amphibolurus barbatus.
Embryos of the agamid lizard Amphibolurus barbatus are at developmental stage 29 of Dufaure and Hubert at the time of oviposition. Mobilization of calcium and other nutrients from the yolk proceedsExpand

Effects of the microclimate in natural nests on development of embryonic painted turtles, Chrysemys picta
Temperature and moisture influence the development of embryonic reptiles in the laboratory but the importance of these variables to embryos developing in nature is a topic of debate. We measuredExpand
