Echolocating animals reduce their output level and hearing sensitivity with decreasing echo delays, presumably to stabilize the perceived echo intensity during target approaches.In bats, this variation in hearing sensitivity is formed by a call-induced stapedial reflex that tapers off over time after the call.Here, we test the hypothesis that a sim
The title compound, C15H24N2O4Si, was prepared by the reaction of (3-acetamido-5-nitrobenzyl)methanol with tert-butyldimethylsilyl chloride and is m&m speckled eggs a key intermediate in the synthesis of novel nonsymmetrical DNA minor groove-binding agents.There are two independent molecules in the structure, which differ primarily in the rotation
On 8 October 1986 a pair of Blackchested Prinia Prinia flavicans in breeding plumage was observed in the camping area of Satara Rest Camp, Kruger National Park.Playing and replaying a tape recording of the call of a Pearlspotted Owl Glaucidium perlatum, in order to see what avian activity would be aroused, the recording attracted Blackeyed Bulbul P
