Abstract for zoosemiotics conference in progress

I have come up with a title for my abstract submission to the conference Zoosemiotics and Animal Representations (Tartu, April 4-8, 2011): 'The Umwelt trajectories of wolves, sheep and people'. This paper will sum up my work on the (in part interactive) life worlds of these creatures, and introduce some new concepts in the process ('Umwelt trajectory' being one).
