STUDIES ON INORGANIC CHEMICAL COMPOSITION IN SKELETONS OF PLATEAU ZOKER AND PLATEAU PIKA I MACROELEMENTS

The contents and distributions of the inorganic macroelements K,Na,Ca,Mg,P and Al in skeletons of plateau zoker( Myospalax baileyi ) and plateau pika ( Ochotona curzoiae ) were studied in the area of Haibei Research Station of Alpine Meadow Ecosystem.The results are as follows: The contents of Ca,P and Al in skeleton of plateau zoker are very significantly higher than that in skeleton of plateau pika (P 0 01),the contents of K in skeleton of plateau zoker are extremely significantly lower than that in skeleton of plateau pika (P 0 001),and the contents of Na and Mg between plateau zoker and plateau pika are not different (P 0 05). The distributions of total amount of macroelements in different parts of skeleton are:plateau zoker leg bonehead bonebackbone,plateau pika head boneleg bonebackbone. In total 15 element pairs,10 pairs for plateau zoker and 13 pairs for plateau pika are significantly correlated.
