Dear Colleagues This is a reminder that the deadline for ordering a Malaise trap is this Saturday, if you want to participate in the NA insect abundance network (see www.insectabundance.org<http://www.insectabundance.org/>) and get a discount on purchasing a trap. We are still looking for collaborators. Please see the earlier message below and the website for more information.
Traps are about $240 each from Forestry Suppliers (item number 54077), including shipping. We are only purchasing the Townes-style model II trap to ensure consistency in our study. If you are interested, please send me your shipping and billing addresses and the number of traps that you want before Saturday. Best, Peter pd...@uwm.edu Peter Dunn Distinguished Professor Emeritus Dept. of Biological Sciences Univ. of Wisconsin-Milwaukee Milwaukee, WI 53211 http://people.uwm.edu/pdunn/ From: Peter O Dunn <pd...@uwm.edu> Sent: Saturday, January 25, 2025 6:02 PM To: ecolog-l@community.esa.org Subject: Collaborators needed for large-scale study of insect abundance in North America Dear Colleagues We are inviting you to join our collaborative network studying trends in insect abundance, the North American Insect Abundance Network (www.insectabundance.org<http://www.insectabundance.org/>). This year we will be starting our 7th year of sampling using Malaise traps at 213 locations spread across Canada and the US. Our study is designed to detect insect declines of 1-5% per year (the long-term averages from meta-analyses). We have already found declines in some taxa and increases in others. Preliminary results can be found at: www.insectabundance.org/news<http://www.insectabundance.org/news>. Please look at the "join us" page on the web site for what you need to contribute. As in the past, all collaborators who send in data will be authors on the resulting papers. Our project is designed so you do not have to do a lot of work collecting and processing samples. The minimum contribution involves setting up a Malaise trap and collecting three samples from it, typically in May & June. Each sampling period is 3 days (72 hrs). Collaborators can sort the samples (to at least Order) and weigh them themselves or send the samples to me for processing. It does not get much easier. The main caveat is that you will need to purchase a Townes-style Malaise trap from Forestry Suppliers (item number 54077). The price is discounted for this project to about $240 ($203 + $36 shipping). If you want this discount on purchasing a trap, please contact me asap (Peter Dunn, pd...@uwm.edu<mailto:pd...@uwm.edu>). This could be an excellent project for public outreach or school projects. It is an engaging and important question that students and the public can help to answer. Thanks, and I look forward to hearing from you. Peter Dunn pd...@uwm.edu<mailto:pd...@uwm.edu> Emeritus Professor of Biol.
