Yes, I hope I made it plain that r- and K- classification is still in use, and that there were a variety of critiques, not just the fact there were are exception to the generalization.
I’m curious tho, some of Pianka’s associated traits have opposite relationships to those stated in big taxonomic groups. Notably for insects, reptiles and fish, “generally” reproductive output increases with body size as compared to mammals and birds where it decreases. As an evolutionary biologist what is your take here? I can think of half a dozen explanations, but never found a literature consensus (e.g., Pianka just got the traits wrong for r—and K and now we use...., r and K- not good for these groups, body size relationships within groups not so important etc etc)
