Abstract:
Objective To explore the rela ti onship between the environmental temperature and the oxygen demand of [WT5” BX]Oncomelania snails, and the relationship between the hiber nation or aestivation and the oxygen demand of snails.Me thods The oxygen demand of Oncomelaniasnails between 0 ℃ and 40 ℃ was determined by increasing the temperature gradually in lab, the relationship between the environmental tempera ture and the oxygen demand, and the correlative relationship between the oxygen demand and the percentage of snails in hibernation or aestivation were analysed. Results The oxygen demand increased as the tem perature rose between 1 ℃ and 36 ℃, and the regression equation between the oxygen demand and the variation of environmental temperature was [WT5”BX ]=6.6?10 -5-3?10 -6x+4.4?10 -6x2-8?10 -8x 3(R2=0.998,F=2775,P
