THE EFFCT OF WIND ON THE NUMBER OF WILD FEMALE HAMSTERS CAPTURED IN SPRING AND SUMMER
The number of wild female hamsters captured was significantly affected by wind, season (F 1,16=13.36,P <0.01), wind (F 1,16=6.82,P <0.01) and the interaction between these variables (F 1,16=25.49, P <0.01, Figure 8A). In spring, 91.3% fewer lactating females were captured on windy days than on calm days, whereas in summer 5-times more lactating females were captured on windy days than on calm days (season,F 1,16=32.40, P <0.01; wind,F 1,16=25.60, P <0.01, interaction, F 1,16=67.60,P <0.01, Figure 8B). The percentage of lactating females captured was significantly affected by season (F 1,16=7.70, P <0.01), wind (F 1,16=4.98, P <0.05) and the interaction between these (F 1,16=49.83,P <0.01, Figure 8C).
