Dear list,

 

I have a question concerning the definition of a "burst" in the adehabitat
package. Somehow I 'm not able to wrap my mind around it and to adopt it
appropriately for my data set.

 

I want to analyze the movement behavior of aquatic invertebrates and how it
may be impacted by different environmental influences. In order to study
this I have set up an arena where I let the animals walk around and video
tape their locomotion over time.

 

However, my image quality is bad at times, or an animal hides under an
object that I placed in the arena, which causes the tracking software to
loose a track but it may pick it up again after some time when the
individual is visible again. Those separate tracks get different numbers by
default.

 

My problem of understanding is now, are the different track ID's that I get
from the tracking software "bursts" or not. It's only one animal per movie I
look at and it's only one movie of, say, one hour that I record and for
which I get track no.1, 2, 3. etc. 

 

According to my current understanding I am dealing with only one burst in a
situation as described above and I would get several bursts, if I would
record one animal for 10 minutes, have a break of 10 minutes, record again
for 10 minutes, etc.

 

I'm sorry if this is a trivial question. But the longer I think about it or
the more often I read about it the more I get confused and unsure.

 

Many thanks for your time!

 

Jacqueline
