Narrator: This is Science Today. Researchers at the University of California, Berkeley, have discovered an unobtrusive way to monitor animal habitats. David Culler, professor of computer science, says that by installing a network of wireless microsensor motes into a habitat, researchers can obtain highly specific, raw data about the environment without being disruptive.
: So for example, if you're monitoring animals, you
can do it in this very unobtrusive fashion. And it
may well be that what we see is quite different than
what people have seen before because they've been
intruding on the very thing that they're trying to
measure. As well as that we're able to measure it
at granularity that they've never been able to perceive
Culler says once the microsensors are installed, the
challenge for biologists will be to process all of
So it's like, when you invent a microscope, there's
all of the sudden all of these organisms that you've
never seen before and all these interactions. So it's
getting information of the physical changes, activities,
across space and time, and then being able to make
sense out of that and take action in response to it.
