摘要
2004~2005年,对人工饲养的长鬣蜥繁殖行为和生态习性进行了研究,结果表明:3~7月为长鬣蜥的繁殖期,繁殖行为主要表现为发情求偶、交配和产卵,5~6月为产卵高峰期,每条成熟的雌蜥年产卵2~3窝,平均窝卵数12(7~18)枚;雌蜥每窝产卵间隔33~45 d不等;平均单卵重3.06(2.80~3.50)g;卵径2.63 cm×1.18cm。在自然孵化温度和90%~95%的湿度下孵化期为60~98 d,孵化率52.34%,长鬣蜥幼体初生个体重2.50 g,体全长(头体+尾)14(4+10)cm。
The reproductive biology of long iguana(Physignathus cocincinus) was observed during 2004 and 2005.Data collected were as follows:period of reproduction was from March to July;eggs were laid in March to July;2~3 clutches of eggs were laid in a year;average number per clutch were 12(7~18) eggs;intervals between clutches were 33~45 days;average weight per egg was 3.06(2.80~3.50) g;egg size was 2.63 cm×1.18 cm;natural incubation period was 60~98 days;incubation ratio was 52.34%;body weight at born was 2.50 g;body length including the tail was 14(4+10) cm.
