Hi Rhonda,

Looking at this again, and also at the master list of listservs (just learned how to do this), I feel confident in saying we (PNW) do not have ownership of any newsbox listserv.

In the example you’ve forwarded, it appears we (PNW) have “piggybacked” on someone else’s listserv (USDA-FS-NEWS) to distribute our material.

What I was imagining was a dedicated listserv for our own material, similar to what SRS has (FS-SRS-PUBS) or RMRS has (RMRS_PUBLICATIONS)

So, I believe I still need to ask “Doc” tomorrow about how to set up a new one.

I learned this by sending the listserv command “LIST” (no quotes) in the message body of an e-mail addressed to LISTSERV [ a t ] NEWSBOX.USDA.GOV. I’m attaching the readout that I got back – it’s interesting (See the attached text file, usda_newsbox_listserv_lists_20170327.txt).

Our distribution method for our four current mailing lists remains a mystery to me:

1. PNW Research News Releases

2. PNW New Publications

3. PNW Science Findings (Is it always “piggybacked” on USDA-FS-NEWS?)

4. PNW Science Update

Do you have any examples of any of these?

A new Science Findings from the PACIFIC NORTHWEST RESEARCH STATION is now available online!

Science Findings 194 – March 2017

Northwest forest plants defeat pests and diseases!

This month’s issue features science by Rick Kelsey and Joe Karchesy


Societies use biologically active chemicals as medicines and pesticides to protect human and agricultural health. But widespread use of synthetic compounds raises concerns about their safety, and resistance development in targeted pests.

To find safer alternatives, scientists turned to native plants and trees in Pacific Northwest forests using multiyear exploratory surveys. Researchers collected samples from different plant and tree parts for extraction and toxicity testing with a simple brine shrimp bioassay. These bioassays detected strong biological activity in heartwood extracts from four cedar and one juniper species.

In followup experiments, researchers discovered that heartwood extracts from yellow-cedar (Callitropsis nootkatensis), incense cedar (Calocedrus decurrens), Port Orford cedar Chamaecyparis lawsoniana), and western juniper (Juniperus occidentalis) had strong toxicity or repellent activity toward mosquitoes, ticks, or fleas. A patent was issued for compounds with activity toward these pests. It has been licensed to a company interested in developing them into commercial products.

In other experiments, researchers found extracts and compounds from cedar heartwood possess strong antimicrobial activity against Phytophthora ramorum, the pathogen causing sudden oak death. To mitigate movement of P. ramorum spores by hikers and cyclists, forest health specialists have used western redcedar (Thuja plicata) heartwood chips on a popular hiking trail on the Rogue River-Siskiyou National Forest, where retreatment continues to show promising results.

About Tanner Jessel

I am a recent M.S. in Information Science graduate from the University of Tennessee School of Information Science. I was formerly a graduate research assistant funded by DataONE (Data Observation Network for Earth). Prior, I worked for four years as a content lead and biodiversity scientist with the U.S. Geological Survey's Biodiversity Informatics Program. Building on my work experience in biodiversity and environmental informatics, my work with DataONE focused on exploring the nature of scientific collaborations necessary for scientific inquiry. I also conducted research concerning user experience and usability, and assisted in development of member nodes with an emphasis on spatial data and infrastructure. I assisted with research designed to understand sociocultural issues within collaborative research communities. Through August 1, 2014, I was based at the Center for Information and Communication Studies at the University of Tennessee School of Information Science in Knoxville, Tennessee.
