Gehrt found that “urban coyote populations are much larger than expected; that they live longer than their rural cousins in these environments; and that they are more active at nighttime than coyotes living in rural areas.” (http://researchnews.osu.edu/archive/urbcoyot.htm.) As a coyote expert, he has written about human-coyote conflicts and how they can be resolved. A document titled Urban Coyote Ecology and Management provides an excellent overview of coyotes and conflict resolution possibilites.
