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).
