An interesting study that shows some unique behaviors for the selected Amur tiger populations. While males have distinct core areas, there are more males in one area as compared to other tiger populations, indicating that male compete in a scramble of sorts for mates.

Thanks for the link. The study is interesting, as it not only shows patterns we didn't know about. It also shows in what way specific local conditions, habitat destruction and prey depletion affect behaviour in a tiger subspecies living on the edge.  

Amur tigers, and males in particular, need a lot of space. Over a century ago, adult males needed 4-14 days to patrol their home range in India. This was in the days of plenty in a densely forested and well-stocked region. Amur males need more time, which allowed other males a chance to use a part of their territory. This situation apparently can continue for years.

Although it could seem different, Amur males with a territory seem to be as territorial as Indian tigers. Based on what I read, I concluded humans and bears also are seen as (permanent) competitors. Conflicts between Amur tigers and bears often are explained as results of food disputes, but territory could be more important than we think. Reply
