The changing trend of progesterone during oestrous cycle resembles with that during the first 14d of early pregnancy. Its content reaches the peak value at lOd after oestrus and then declines. The estradiol peak appears at 3d of oestrous cycle, and the level rises again before oestrus. The concentration of LH declines after oestrus. The level of follicle stimulating hormone reaches the peak value at lOd after oestrus (2.40mIU/ml).

The echolocation signals of Rhinolophidae and Hipposideridae are both long CF-FM with 1 harmonic and narrow FM bandwidth. But Rhinolophidae has longer duration, higher duty cycle and lower dominant frequency than Hipposideridae. All the echolocation signals of Vespertilionidae are short FM with 2-6 harmonics and wide FM bandwidth. Vespertilionidae has shorter duration and lower duty cycle than the other two families. There are obvious differences in dominant frequency between different species in this family.
