How animals change their movement patterns in relation to the
environment is a central topic in a wide area of ecology, including foraging
ecology, habitat selection, and spatial population ecology. To understand
the underlying behavioral mechanism involved, one can use the first passage
time as a measure of search effort along a path. Ill be presenting the use
of first passage time in analyzing the area restricted search and habitat
selection. This is based on a paper by Per Fauchald and Torkild Tveraa.
