Summary:
A novel methodology that, for the first time, combines
3-D and advanced range estimator technologies to provide highly detailed data
on the range and movements of terrestrial, aquatic, and avian wildlife species
has been developed by researchers. One aspect of the study focused on learning
more about the range and movements of the California condor using miniaturized
GPS biotelemetry units attached to every condor released into the wild.

A team including researchers from the U.S. Geological Survey
(USGS) and the San Diego Zoo Institute for Conservation Research has developed
a novel methodology that, for the first time, combines 3-D and advanced range
estimator technologies to provide highly detailed data on the range and
movements of terrestrial, aquatic, and avian wildlife species. One aspect of
the study focused on learning more about the range and movements of the
California condor using miniaturized GPS biotelemetry units attached to every
condor released into the wild.
"We
have been calculating home ranges for the tracked condors in three dimensions
for the first time using this GPS location data, and our novel density
estimator was used to incorporate the vertical component of animal movements
into projections of space-use," said James Sheppard, Ph.D., a postdoctoral
associate at the Institute for Conservation Research.
While its
population now stands at approximately 400 birds, up from only 22 in the
mid-1980s, conservation efforts to reintroduce the California condor to its
former habitat in the mountains of California and Mexico have been hampered by
a lack of understanding about condor movement patterns and habitat use.
"This
data will be used as a predictive management tool to inform conservation
efforts to restore condor populations, particularly with regard to emerging
threats such as climate change and wind energy impacts," added Sheppard
The team
created highly detailed data sets and visualizations relying on expertise from
researchers at the San Diego Supercomputer Center (SDSC) at the University of
California, San Diego, after they tracked three highly iconic but threatened
species: California condors, giant pandas, and dugongs, a large, marine animal
somewhat similar to the manatee.
"We
were able to speed up their software by several orders of magnitude," said
Robert Sinkovits, SDSC's director of the Scientific Applications Group, which
helps researchers make optimal use of SDSC's larger supercomputers. "In
this case, calculations that had formerly taken four days to complete were
finished in less than half an hour."
