Intestinal helminth communities in long-billed curlews: the importance of congeneric host-specialists.

This paper examines patterns of structure in the helminth communities of long-billed curlews collected on their breeding grounds in Alberta, Canada. The communities are neither large nor species rich but they do show evidence of having structure which is mediated by interactive mechanisms between some helminths. In particular, we focus on the role played by congeneric host-specialists in contributing to community patterns and suggest that even in low diversity systems, some species may set the stage around which other species must assort.
