... (Table xx)". Structures of these sections also differ unnecessarily among model sets,as do headings of tables <strong>and</strong> model names.Response: References to results have been added in the main text as recommended. Wehave improved the consistency of the different sections describing results.56. Table A4-3 does not specify which variables were included in several cases, butinstead uses general labels such as water quality variables, bird predators, fishpredators, etc.Response: We have generated consistent tables that explicitly describe all variables for allmodel sets.57. Reduce the number of decimal places in tables. Provide st<strong>and</strong>ard journal-type tablecaptions to clearly define each column heading <strong>and</strong> other symbols.Response: We have reduced the number of decimal places used in the results tables. Wehave revised the table captions to clearly explain each column heading <strong>and</strong> any symbolsused.58. In Table A4-14, what does "Correction" refer to? You should be using the AIC cformula (i.e., the one corrected for small sample size) instead of the one for AIC. Theformer equals the latter if sample size is large enough.Response: We used the AICc in our model selection however, we have also reported boththe raw AIC <strong>and</strong> the correction in the table (AICc=AIC+correction), this was simply toillustrate the impact of the relatively large number of parameters to observations. We haveclarified this in the table captions.59. The sentence near the top of page 167 does not appear justified: "This appears toprovide some additional confirmation that organizing the qualitative <strong>synthesis</strong> <strong>and</strong>evaluation of evidence by lifestage was indeed justified." Just because results aredifferent for the analysis organized by life stage from the one set up by CohenCommission project does not necessarily mean that the first rank ordering of models ismore valid; it only says that they are different.Response: We have removed this sentence, both from this location <strong>and</strong> where a similarstatement was made in the main body.60. Page 167 - Here is good example of why one of my earlier comments is important.Model 8 turns out to be best (lowest AIC in Table A4-22), yet Table A4-4 does notspecify which temperature measure is used in the Strait of Georgia (when <strong>and</strong> where).Several options were described previously, so the variable that was used is not obvious.Response: Yes, we agree. We have added tables to explicitly list the variables included in135
