| 摘 要： | 为摸清蝌蚪控制藻类生长的效果,用中华蟾蜍指名亚种蝌蚪和花姬蛙蝌蚪在实验室内用红枫湖水进行塑料盆养殖试验.结果表明,随着蝌蚪密度的增加,对蓝藻的总捕食量明显增加,但每只蝌蚪的平均捕食量随蝌蚪密度的增加而下降.中华蟾蜍指名亚种蝌蚪不喜食绿藻,蓝藻密度降低使绿藻获得较多的营养源而大量繁殖,导致绿藻密度增加.同时展望了蝌蚪在水...

| Abstract: | Predatory effect of tadpoles of Bufo gargarizans gargarizans and Microhyla pulchra on algae was studied in laboratory to know the control effect of tadpoles on algae.The result showed that the predation number of tadpoles on Cyanophyta increased evidently,but the average predation number of individual tadpole decreased with the increase of their population density.The tadpoles of B.gargarizans gargarizans disliked preying on Chlorophyta,therefore Chlorophyta had high population density due to nutrient uptak... |
