[Pollinator] Last call for discount on Malaise traps through the NA Insect Abundance Network

[Peter O Dunn]

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

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). This year we will be starting our 7th year of sampling using Malaise traps at 213 locations spread across Canada and the US.  Our focus is on insects in open, grassy areas, but this can include a variety of human-modified areas too, such as agricultural areas and golf courses.



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: https://nam02.safelinks.protection.outlook.com/?url=http%3A%2F%2Fwww.insectabundance.org%2Fnews&data=05%7C02%7CPdunn%40uwm.edu%7C686ec0f5f7524bf1154608dd4231ef0b%7C0bca7ac3fcb64efd89eb6de97603cf21%7C0%7C0%7C638739504434829388%7CUnknown%7CTWFpbGZsb3d8eyJFbXB0eU1hcGkiOnRydWUsIlYiOiIwLjAuMDAwMCIsIlAiOiJXaW4zMiIsIkFOIjoiTWFpbCIsIldUIjoyfQ%3D%3D%7C0%7C%7C%7C&sdata=ogq2MWnA5rU3BGarbn5M2Q2syGjspbvLA4r8WdnSK6M%3D&reserved=0<https://nam02.safelinks.protection.outlook.com/?url=http%3A%2F%2Fwww.insectabundance.org%2Fnews&data=05%7C02%7CPdunn%40uwm.edu%7C686ec0f5f7524bf1154608dd4231ef0b%7C0bca7ac3fcb64efd89eb6de97603cf21%7C0%7C0%7C638739504434839421%7CUnknown%7CTWFpbGZsb3d8eyJFbXB0eU1hcGkiOnRydWUsIlYiOiIwLjAuMDAwMCIsIlAiOiJXaW4zMiIsIkFOIjoiTWFpbCIsIldUIjoyfQ%3D%3D%7C0%7C%7C%7C&sdata=x1hUXbwXmDKiZLgpLmlFBL2ovzwYjc5I3%2BqguEIaqSg%3D&reserved=0<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 before 15 Feb with your billing and shipping addresses and quantity of traps desired (Peter Dunn, pdunn at uwm.edu<mailto:pdunn at uwm.edu<mailto:pdunn at uwm.edu%3cmailto:pdunn at 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.
