For turn-in:
Perform the calculations and report the information requested in paragraphs with boxes (🡪). Answer the questions 1- 4, above, as well as the summary questions below.
(5) Find two species that yielded very different results in seine vs. eletrofishing samples (eg, many in seine but not electrofish, or vice versa). Use what you know about the gear we used and the biology of those species to explain why we caught such different numbers with one gear vs. another.
(6) Given all the information we have, how many __Central Stonerollers__ do you think were present in the site? (Upper for Tues, Lower for Thurs) Which estimation method (census, batch mark-recapture, depletion) seems most reliable to you for that species, and why? What factors (gear, assumptions, species biology) do you think affected the reliability of our estimates? Assume that our data are “real”, and differences between estimates don’t come from mistakes on our part.
