Question

Grey squirrels are known to defend exclusive territories against conspecifics during the summer, and hibernate communally during the winter. You have put radio transmitters on a close relative, the red squirrel, and you have used the radio signals to estimate the mean and variance in the number of squirrels per hectare. Based on the monthly variance-to-mean ratios below, is there evidence that red squirrels also have summer territories and communal hibernation? Explain why Month VM Month V/M Jan: 2.92 Feb: 3.13 Mar: 2.29 Apr: 0.95 May: 0.47 June: 0.23 July: 0.17 Aug: 0.22 Sept: 0.67 Oct: 0.72 Nov: 1.88 Dec: 3.41

Explanation / Answer

No

As the V/M ration in summer months ( April to October) is low. that means the mean is higher than the variance. Low variance means in-activity of the red squirrel as they do not move much. and hence it can be concluded they hibernate during summers ( April to October) and move during winters
