摘要
The yellow pond turtle Mauremys mutica is widely cultured using both greenhouse-reared and outdoor pond-reared models.Individuals from the two models often show different tolerances to dramatic temperature changes caused by extreme weather events.However,the mechanism underlying the difference is unclear.In this study,we found that for greenhouse-reared turtles(GRTs),the expression levels of an immune-related gene for transferrin were significantly different(P<0.05)between the control group and the acute cold stress(ACS)group for most time points(3 h,6 h and 48 h),while at two time points(6 h and 12 h)there was a significant difference(P<0.05)between the control group and the acute heat stress(AHS)group.However,for the outdoor pond-reared turtles(OPTs),we found the opposite pattern:the ACS group showed no significant difference(P>0.05)from the control group for all time points(3 h,6 h,12 h,24 h and 48 h),whereas two time points(12 h and 24 h)were significantly different(P<0.05)for the AHS group.Our results indicate that ACS may influence the immunity of GRTs and have no influence on OPTs,whereas AHS may largely affect the immunity of OPTs and have little influence on GRTs.The findings provide insights into the mechanism underlying the different morbidity and mortality rates of turtles from different culture models after extreme weather events.
