Temperature Response of Local Soil Springtail Protaphorura bicampata(Gisin,1956) (Collembola:Onychiuridae) in Sanjiang Plain
摘要
Abstract
Soil Collembola is one of vital meso-faunal invertebrates in soil ecosystem and most important compartment of soil biodiversi-ty.The knowledge of survival strategy of Collembola is helpful for understanding the transforming procession of terrestrial ecosystem and mechanism of regional maintaining of biological diversity.Low temperature adaptation is one of the important issues of survival strategy of Collembola in wetland of Sanjiang Area, Northeast China.The soil fauna investigated in Sanjiang Plain showed that the species Prot-aphorura bicampata ( Gisin, 1956) was the dominant Collembola population in the cultivated field and the wetland of Sanjiang Plain. The results showed that the most favorable temperature for growing and eggs hatching rate of P.bicampata (Gisin, 1956) was 25℃, but the optimal breeding temperature was 20℃.When temperature was below 15℃, the growing slowed down and breeding stopped. The results illustrated that the dominant Collembola, P.bicampata ( Gisin, 1956) was not an extreme winter active species compared to some Antarctic collembola species which can live even below -30℃.P.bicampata ( Gisin, 1956) might overwinter via eggs but not adults and the main survival strategy might be dormancy or vertical migration.As a behavior adaptation, vertical migration might be fundamental for over-wintering.关键词
