Reproductive Tactic And Life-history Of White-striped Grass Lizard Takydromus Wolteri(Lacertidae) In Heilongjiang Province

White-striped grass lizard is a reptile species lays eggs in camp mode, is the study ofegg-laying pattern evolutionary sense good experimental material. This experiment bycombining laboratory and field method to study the ecological environment of the coldwhite-striped grass lizards to adapt to the environment. Main research contents include:the temperature on the white-striped grass lizard eggs hatch, the influence oftemperature on the white-striped grass lizards breeding strategy, the influence oftemperature on the motor performance, the influence of the white-striped grass lizardtail effects on athletic performance the white-striped grass lizard and the sexdimorphism of the white-striped grass lizard phenomenon research. The main researchresults and conclusions were as follows:Temperature on the white-striped grass lizard eggs hatching effect significantly,including hatching success rate and incubation period. In the egg incubation point ofview,30°C temperature conditions is the optimal choice in all trials, But comprehensivehatched larva body various metrics,27°C is better. With the decrease of spawningfrequency increase eggs, then shorter incubation period.White-striped grass lizards reproduce and head body length, body weight is linearpositive correlation. Weight of breeding more significant than the influence of headlength; Juvenile head length and head of the mother’s body length is linear positivecorrelation; Laying eggs earlier, have a big head length matrix and more nest egg.Tail cutting performance impact on the white-striped grass lizards, including pausetimes, maximum sprint distance and maximum sprint speed, etc. Under the sameconditions under the influence of the outside world, due to saurians tail of body part, toits activity has very important influence. Experimental results for the first time brokentail movement, best proves that under the same external conditions of the tail morecomplete white-striped grass lizards sports ability more strong.Temperature is one of the important factors affect the white-striped grass lizardsreproduce, extreme high or low temperatures on the white-striped grass lizards areunfavorable. White-striped grass lizards reproduce for temperature of30°C or so.This experiment is discussed from the white-striped grass lizards mate, lay eggs, eggshatching, larvae growth for its a series of process is affected by temperature anddifferent performance, reproductive characteristics, the white-striped grass lizard wasinvestigated in different stages of the life history characteristics, and in order to adapt tothe white-striped grass lizard alpine environment of breeding strategy.
