Energy contents and their seasonal variations in arachnida

研究干旱地区蛛形纲动物的含能值变动规律。

The energy content and their seasonal variations of Arachnida in arid environment were studied .

The energy content of Arachnida exhibited significantly seasonal variations and the maximum was found in autumn ( 23.05J / mgAFDW ) and the minimum in spring ( 19.58 J / mg AFDW ) .
