Bat Activity Increases with Barometric Pressure and Temperature during Autumn in Central Georgia

摘要: Abstract Activity patterns of bats are known to vary among nights, seasons, years, and geographic regions, but the underlying reasons for those poorly understood. Our objectives were assess temporal variability bat activity during autumn in central Georgia, evaluate influence barometric pressure nighttime temperature on nightly using Akaike's information criterion regression models. We recorded 43,168 calls 5839 sequences an ANABAT SD2 detector 65 sample nights (4 September 11 November 2011) at a residence Barnesville, GA. The number ranged from 3 551. Nightly was positively related average pressure. In contrast our expectations, not changes prior or nights. positive relationship between activity, temperature, may be t...
