The Effects of Weather on the Activity of the Masked Shrew

摘要: The activity of a Laurentian population Sorex cinereus (Kerr) was recorded using the sand transect technique. Data were analyzed to determine effects weather on shrew activity. Rainfall increased nocturnal but nature relationship difficult establish. time when precipitation started important in determining response highest rainfall interval 1800 2400 hours. onset influenced hourly In general, or decreased as result corresponding increase decrease mean temperature from that previous night. Nocturnal cloud cover had significant influence total daily activity; cloudy nights. Although wind direction did not have statistically activity, higher southerly winds prevailed. Effects speed and duration, barometric pressure, relative humidity, significant.
