The Influence of Temperature on Vertical Migration of Invertebrates Inhabiting Different Soil Types

摘要: The main purpose of this study is to determine, as far possible, the effects temperature variations upon soil invertebrates during colder months year; and determine whether they move deeper into fall winter in order escape region near surface return following spring. It a generally accepted principle that undergoes reversal gradient spring somewhat similar lakes other bodies water. has been shown by certain investigators some invertebrate fauna descend lower warmer depth coincident with overturn come closer overturn.
