| Abstract |
Noise caused by human activities can cause stress in animals. We examined whether noise from construction sites affects the behaviour of and exhibit use by three Snow leopards Uncia uncia at Basel zoo. The behaviour and location of the animals were recorded at 1 minute intervals, using the instantaneous scan sampling method over a period of 216 hours (104 hours on noisy days and 112 hours on quiet days). The animals differed individually in their responses to the construction noise. On noisy days, the Snow leopards generally spent less time in locomotion and more time resting, but even on quiet days, resting was the predominant behaviour performed. Under noisy conditions, they increased social resting and decreased resting alone. Walking and social walking were also reduced on noisy days. Furthermore, the Snow leopards spent considerably more time in the remote offexhibit enclosure under noisy conditions. Independent of background noise, they stayed more than half of the time in the caves and the forecourts of the outdoor enclosure. On quiet days, the Snow leopards used more sectors of their exhibit than on noisy days. The results indicate that the Snow leopards responded to construction noise by increasing the amount of time spent resting and by withdrawing to the remote parts of their exhibit. |

| Abstract |
Three mature nulliparous female leopards were studied for 5 years. During three separate 6-month periods serum oestradiol and progesterone concentrations were measured at weekly intervals. Oestradiol was elevated over 21 pg/ml for 54 weeks during these 3 periods, and 36 oestradiol peaks (65\m=.\8\m=+-\6\m=.\3pg/ml (mean \m=+-\s.e.m.), range 21\p=n-\172pg/ml) were identified. Daily frequency of feline reproductive behaviours averaged over each week increased from 1\m=.\9\m=+-\0\m=.\2(n = 93) during weeks with low serum oestradiol concentrations (<21 pg/ml) to 5\m=.\3\m=+-\0\m=.\6(n = 54) during weeks when serum oestradiol concentrations (>21 pg/ml) were high. Increased serum progesterone concentrations (13\p=n-\98n/gml) were observed on 5 occasions in 2 leopards housed together. These presumptive luteal phases lasted from 1 to 5 weeks. Baseline progesterone values were 1\m=.\6\m=+-\0\m=.\4 ng/m(nl= 131). No progesterone increments were observed in isolated animals, and serum concentrations remained at baseline levels. These limited observations suggest that female leopards do not require intromission to induce ovulation and luteal function. The average interval between oestradiol peaks for cycles with no progesterone increment was 3\m=.\4weeks (range 1\p=n-\6weeks). The interval for the 3 complete cycles associated with elevated progesterone concentrations was 7\m=.\3weeks. Analysis of sexual behaviours over the 5-year study period revealed no evidence of seasonality in these
captive leopards. |
