A Bioenergetics Approach to Developing a Population Consequences of Acoustic Disturbance Model
In an effort to know how measurable short-term responses result in biologically meaningful changes in populations, a National Research Council Committee developed the population consequences of acoustic disturbance (PCAD) framework (National Research Council 2005). This framework detailed how behavioral responses to sound may affect life functions, how life functions are linked to vital rates, and how changes in vital rates cause population change through a series of transfer functions. However, many of these transfer functions are poorly understood. Here a bioenergetics model is described that can be used to parameterize these transfer functions and can identify species and/or particular life history characteristics that are likely to be sensitive or resilient to acoustic disturbance.
