Presidential Address: The orca conjecture
Abstract In this address, I argue that the Southern Resident Killer Whale (SRKW) population has been negatively affected by commercial vessel traffic, tied to international trade, in the post‐1998 period. I present new data showing a dramatic increase in both the volume of kilometres travelled and t...
