Preliminary Observations on Postembryonic Development of Rana kunyuensis;

An Investigation on the Alien Invasive Plants in Kunyu Mountain,Shandong Province;

Preliminarily Investigation on Medicinal Fungi in Kunyu Mountain of Shandong Province;

A study on the germplasm resources of medicinal plants in Kunyu Mountain;

An investigation of the macrofungi of Mt.Kunyu,Shandong Province;

Exploitation and utilization of wild economy plants in Mt.Kunyu;

A Preliminary Study on Resource of Medicinal Bryophytes of Mt.Kunyu in Shandong Province

The results as follows:Insect density of Cephalcia lariciphila and stand has tight relationship,and also got a maths model of dynamic transition rules;logistical between Cephalcia kunyushanica Xiao and stand factors including elevation,slope gradient,slope aspect,slope location.

Nutritive Material of Rana chensinensis by Multivariation Analysis Methods;

Being affected by it,the mercury concentration in the plants and the amphibian,Rana Chensinensis of the polluted samples was much higher than that of the unpolluted samples.

In this disquisition, the research mostly concentrated on the results that the Rana chensinensis which was the typical amphibian in the river- forest wetland of northern China and its tadpole absorbed and concentrated mercury and methyl-mercury.

Anatomical and histological structures of ovary, oviduct, uterus and testis of forest frog were detailed based on the anatomical observation and H E stain of sexual glands.

The phenomenons such as growth slowly, high death rate, the change of behavior and the growth of young frog have been studied within the feeding population of the forest frog moved to the South.

LPⅠ,the mixture of antibiotic protein and peptide was separated from skin of Changbai Mountain forest frog with gel filtration chromatography.
