What are the best resources for designing field studies? (from Mina)

Jeremy: Look at this picture and ask yourself, “Do I really want this guy’s advice on field study design?” 😉


Hold your field sites firmly, so that you don’t drop them.

Brian: There are two good books on field methods: Henderson & Southwood and Krebs  I can recommend both first hand (they both sit in prime places on my bookshelf). There are plenty of others if you look that seem fine but I can’t personally recommend them. Then of course there is the more broad subject of experimental design. There’s a ton of books on that topic and I don’t have a specific one to recommend (although Box’s book is a classic). But you can do worse than just go read Hurlbert’s paper on pseudoreplication (Meg’s post on this paper). There is a whole section (3 chapters) in Gotelli & Ellison’s Primer of Ecological Statistics that is also very good.

I take it as a given that you are already accessing colleagues and  mentors as a key resource as well. Experimental design is an art with a lot of peculiarities particular to a system (you mention being a forest ecologist) and most of this is uncapturable in a book.

But I would also just give you kudos for asking the right question. Many people want to ask what is the right statistical method. But asking what are the right field methods and experimental designs are actually much more important (and have to be decided much earlier and ignored by more people).

Jeremy adds: I actually thought of suggesting Southwood [who was the sole author of the earlier edition that I own], but didn’t because I wasn’t sure if it’s still regarded as the best reference. So now having seen Brian’s recommendation and having total confidence in anything Brian recommends, I’m unreasonably proud of having almost given advice that would’ve been good if I had given it. 🙂

  1. As the resident muddy boots field biologist, clearly I failed by not getting to this one in the queue! Sorry about that. Now back to reading applications….

  2. I would add: read papers that do experiments/observations similar to the ones you want to do. Good papers will both explain the methods in detail and talk about their limitations in the discussion. If a method in a particular paper seems promising, contact the authors and ask about all the *stuff* that didn’t get into the paper. (e.g. “We didn’t mention in the paper that the first time we tried this experiment, wild rabbits ate all the plants. You really need to make sure to put up a fence around the whole thing.”)

  3. Thank you! Thanks to Jeremy for the laughs and to Margaret and Brian for the advice. I will look into investing in those texts. I appreciate it, sampling design was somehow a class I skipped in grad school and I’ve regretted it ever since.
