For those who would like to read a summary of the recent biophony
study we did in Sequoia National Park for the National Park Service,

1 September, 2003
Location: Sequoia National Park (SEKI), four different sites
Start date: 1 October 2001
Scheduled completion date: 30 September 2002
Abstract: Using the sound signatures of four representative sites
within Sequoia National Park to test for evidence of habitat health,
the biophonies and geophonies were recorded at selected times during
each of the four seasons beginning in October, 1991 and ending in
August, 1992, and analyzed with respect to frequency niches, temporal
expression of sound, and spatial techniques. It was the objective of
this pilot study to determine if there was sufficient information and
the ability to analyze the data as indicators of habitat health and
relative dynamic equilibrium. Indications support the thesis that
organism vocalizations within a given landscape at dynamic
equilibrium will exhibit patterns of clear discrimination between
frequency niches and/or temporal slots. The clearer the patterns, the
more stable the system.
Enjoy!
