Effect of Temperature on Development and Adaptability of Pelophylax nigromaculatus Tadoples
摘要
Abstract
To investigate the effects of temperature on development and adaptability of Pelophylax nigromaculatus tadpoles.Pelophylax nigromaculatus tadpoles were domesticated at water temperatures of 7℃,17℃,and 27℃,respectively.Four morphological measurement including,body weight,total length,tail length,and body width,were measured.The changes in various morphological indicators were analyzed,as well as the study of the optimal temperature,escape temperature,and lethal temperature.During the period of rearing for 1 to 7 days,the growth rates of body weight,body width and total length in the 27℃group were higher than those in the 17℃group.Under domestication conditions of 7℃,17℃,and 27℃,the optimal temperatures are 28.44℃,30.03℃,and 30.70℃,respectively;The escape temperatures are 25.49℃,31.77℃,and 31.78℃,respectively;Its high-temperature lethal temperature is 38.0 to 40.5℃.The results showed that 27℃is a suitable breeding temperature for Pelophylax nigromaculatus tadpoles.After domestication at different temperatures,there is a significant difference in the optimal temperature(P＜0.05)and escape temperature(P＜0.01),while there is no significant difference in the high-temperature lethal temperature(P＞0.05).The adjustment of the domestication temperature,can improve its to environmental temperature fluctuation.关键词
