Re: [ECOLOG-L] Entomological Wet Pitfall Traps
I've always just used disposable plastic drinking cups for ptifall traps. They are inexpensive, light-weight to carry in the field, and easy to replace if damaged. I usually use 2 cups per trap, this way the outer one stays in the ground and the inner one can be removed to empty/check. If you're doing multiple checks throughout the season, it minimizes soil and litter disturbance once they are set. Lids are a tough thing because you want the insects to crawl in unhindered but limit small mammal captures. I typically use a styrofoam plate and some long nails to support the plate. In places where I've had lots of raccoon activity (they like pulling traps out), I've used a square of chicken wire over the trap held in place with lawn stakes. It helped, but I don't know how that impacted insect captures. How often are you going to check the traps? I'd recommend propylene glycol for the wet component. I've used the low-tox antifreeze, but marine/RV antifreeze is cheaper (it does contain water, but I haven't had much issue with it). Ethylene glycol will attract mammals and will likely shift your traps from passive to active for insects. Even after a week or two, the insects should still be preserved well enough to ID in propylene glycol.

After exploring options on BioQuip, I've noticed that most pitfall traps are cheaply made. The Colorado Parks and Wildlife and the USFWS require that I put a lid on the wet trap to keep animals out. I am debating on what would be the best way to either construct or purchase these traps, and whether I should use formaldehyde (10%) or ethylene glycol in the traps. Does anyone out there have experience that they would like to share or any suggestions for how to construct an animal-proof wet pitfall trap? -- Samm Rowland Masters in Environmental Management Integrated Land Management Western Colorado State University 917.763.1271 sammantha.rowl...@western.edu
Re: [ECOLOG-L] lessons for new faculty members?
I feel both mildly offended and complimented by Aaron Dossey's comments regarding new faculty hires. I'm offended because he asserts what I have done recently is outside of the realms of reality, yet I'm complimented because I have done it. Starting this fall, I will be a new faculty member in a department and at a university where I have no prior affiliation. I also have no prior associates. I'm finishing a post-doc at a different university in a different state; I didn't know the department chair, faculty, staff, or anyone on the search committee; my advisors and supervisors didn't have affiliations or associations with the department or the university; and I am not a trailing spouse. So, I am a new faculty member this fall who did get the job because of my CV and interviews. For those of us who are new faculty, lessons and wisdom from veteran faculty are greatly appreciated Jordan -- Jordan M.

Re: [ECOLOG-L] Catching soil invertebrates
Dave In my experiences with pitfall traps, I don't recall capturing many earthworms. I have captured occasional snails, slugs, and some larvae, more likely to capture insect nymphs. If you do use pitfall traps, I have always used propylene glycol as the killing agent/preservative, 2-4 cm deep, since it isn't too attractive to insects or mammals. This is the main ingredient in low toxicity antifreeze and most boat/RV antifreeze. The labels are pretty clear regarding the ingredients. I wouldn't use ethylene glycol, main ingredient in most other antifreeze. This is attractive to insects and mammals. Since pitfall traps are usually passive, an attractant isn't usually wanted. Even using propylene glycol, you will capture some mammals in pitfall traps; shrews and voles are the most common in my experience. Checking traps every week or 2 weeks is acceptable, I have done both for different studies. For sampling earthworms, I would think soil cores (10-15 x 25 cm?) or small soil pits (25 x 25 x 25 cm?) would be the most effective technique. Sieve the soil and remove the earthworms.
