摘要
北草蜥（Ｔａｋｙｄｒｏｍｕｓｓｅｐｔｅｎｔｒｉｏｎａｌｉｓ）卵从孵化基质吸收水分导致质量增加。２４℃湿度对孵化卵的终末质量无显著影响；２６℃和２８℃时，高湿度孵化的卵终末质量较大。孵化卵终末重与初始重呈正相关，终末卵重的差异部分地由初始卵重决定。温度对孵化期、孵化成功率及孵出幼体的大小、质量和疾跑速有显著影响：孵化期随孵化温度升高而缩短，２４℃和２６℃的孵化成功率显著高于更高温度的孵化成功率，较低温度孵出的幼体较大、较重。本研究设置的湿度对孵化期、孵化成功率及孵出幼体的大小、质量和疾跑速无显著影响。孵化温湿度与孵出幼体的性别无关。
Pliable shelled eggs of Takydromus septentrionalis increased in wet mass over the incubation due to absorbing water from the substrate.The levels of substrate moisture significantly influenced final masses of the eggs incubated at 26 and 28℃.Eggs gained more mass in wetter substrates than in drier substrates.In contrast to those at 26 and 28℃, final masses of the eggs incubated at 24℃ were independent of the level of substrate moisture.Due to the positive relationship between final and initial egg masses seen in all cases, variations in final egg mass could be partly explained by the variation in initial egg mass.Within the range from 24 to 32℃, incubation temperature significantly influenced duration of incubation, hatching success, and size, mass, and sprint speed of hatchlings, with the eggs incubated at 24 and 26℃ exhibiting higher hatching successes and producing larger, heavier, and faster running hatchlings.Within the range from -220 to 0 kPa, incubation hydric environments had no impacts on duration of incubation, hatching success, and size, mass, and sprint speed of hatchlings.Incubation thermal and hydric environments did not determine sex in T septentrionalis.
