The biodiversity crisis in global forests continues to be accelerated by habitat loss and consequent extinctions of floral and faunal species assemblages that cannot adjust to rapid, and often large scale, habitat alterations. In an effort to record arthropod diversity in northern temperate rainforests we have studied canopy arthropods in a number of Vancouver Island rainforest types since 1992. Based on these findings we summarize results to answer the following questions: (1) Does guild proportionality vary among different, geographically separated ancient rainforests? (2) Does the numerical dominance of the predator guild by spiders change across these ancient rainforests? (3) Do these ancient rainforests act as repositories for arthropod biodiversity? Answers to these questions are needed to address the issues that surround the maintenance of biological diversity (form and function) in these ancient forests and, in a broader context, rainforests throughout the world.
