Figure 1. The effect of ambient temperature (21°C and 32.5°C) and simulated wind on the body mass (A) and food intake (B) of lactating, female striped hamsters (Cricetulus barabensis ). Females were housed at either 21°C or 32.5°C from Day 5 of the experiment and exposed to simulated wind from Day 6; NW = no wind, W = simulated wind. Data are means ± s.e. P temindicates the period in which there was a significant temperature effect and P w the period in which there was a significant wind effect; *P <0.05, **P <0.01.
Figure 2. The effect of ambient temperature (21°C and 32.5°C) and wind on the asymptotic food intake (A), gross energy intake (GEI, B), digestive energy intake (DEI, C), gross fecal energy (GEF, D), digestibility (E) and milk energy output (MEO, F), of lactating, female striped hamsters (Cricetulus barabensis ) between day 13-14 of lactation. Females were housed at either 21°C or 32.5°C from Day 5 of the experiment and exposed to simulated wind from Day 6; NW = no wind, W = simulated wind. Data are means ± s.e. P temindicates a significant temperature effect and P wa significant wind effect; **P <0.01.
Figure 3. Effect of ambient temperature (21°C and 32.5°C) and wind on the relationship between asymptotic food intake and the body mass (A), milk energy output (MEO, B), litter size (C) and litter mass (D), of lactating, female striped hamsters (Cricetulus barabensis ). Females were housed at either 21°C or 32.5°C from Day 5 of the experiment and exposed to simulated wind from Day 6; NW = no wind, W = simulated wind. ** P <0.01.
Figure 4. Effect of ambient temperature (21°C and 32.5°C) and wind on the relationship between milk energy output (MEO) and the body mass (A), litter size (B) and litter mass (C), of lactating, female striped hamsters (Cricetulus barabensis ). Females were housed at either 21°C or 32.5°C from Day 5 of the experiment and exposed to simulated wind from Day 6; NW = no wind, W = simulated wind. **P <0.01.
Figure 5 The effect of ambient temperature (21°C and 32.5°C) and wind on the litter size (A), litter mass (B) and pup mass (C), of lactating, female striped hamsters (Cricetulus barabensis ). Females were housed at either 21°C or 32.5°C from Day 5 of the experiment and exposed to simulated wind from Day 6. NW = no wind; W = simulated wind. Data are means ± s.e. P temindicates the period in which there was a significant temperature effect and P w the period in which there was a significant wind effect; *P <0.05, **P <0.01.
Figure 6 The effect of temperature and wind on the water loss (A, B) and cooling rate of a plain glass vessel (C, D) and the cooling rate of a glass vessel wrapped in the fresh pelt (E, F) of a striped hamster (Cricetulus barabensis ). NW = no wind; W = simulated wind. Data are means ± s.e. P tem indicates the period in which there was a significant temperature effect andP w the period in which there was a significant wind effect; *, P <0.05, **, P <0.01.
Figure 7. Effect of ambient temperature (21°C or 32.5°C) on the number of pups moved by female striped hamsters (Cricetulus barabensis ) to sheltered cages (A) vs cages exposed to simulated wind (B), and the amount of time females spent in sheltered cages (C) vs cages exposed to simulated wind (D). Data are means ± s.e.
Figure 8. Effect of wind on the number of wild, lactating, female striped hamsters (Cricetulus barabensis ) captured in live traps on windy and calm days in spring and summer. (A) total number of females captured, (B) number of lactating females captured, and (C) percentage lactating females captured. Data are means ± s.e..P s indicates significant seasonal effects andP w significant wind effects; *P <0.05, **P <0.01.
Figure S1 The effect of ambient temperature (21°C or 32.5°C) on the amount of time striped hamster (Cricetulus barabensis ) pups spent in cages that were exposed to simulated wind (green rectangles) or sheltered cages (brown rectangles), or both (grey rectangles). Each rectangle represents 10 min.
Figure S2 The effect of ambient temperature (21°C or 32.5°C) on the amount of time that lactating, female striped hamsters (Cricetulus barabensis ) spent in cages that were exposed to simulated wind (green rectangles) or sheltered cages (brown rectangles). Each rectangle represents 10 min.
