Getting Our Feet Wet

This is the second in a series of posts by our intern Jeff  Jaureguy.

Day 2
June 26, 2016
Ed on the finer points of beating-sheet collecting.Creative Commons License
Sunday morning and still no electricity in the hotel due to the storm from the previous night.  Loaded the cars and headed out to on our first field site at the Namekagon River in Bayfield County SACN.  We split into two groups to explore under a bridge nearby to collect samples.  I scavenged the cement wall directly under the bridge near the stream and found many dead samples of stoneflies within spider webs. 
After this bridge excursion we headed to the park area where there was an entrance into the river.  Dr. DeWalt brought out dip nets and beating sheets and taught us how to use these tools properly to collect the insects.  Dip nets are used to collect aquatic insects on the bottom of the river floor while being submerged in the water.  After using the the dip net, the contents are poured into a tray to sift through and pick out the aquatic insects of varying species.  Beating sheets are a diamond shaped sheet used to collect insects off plants by beating the plants with a short stick until the insects fall onto the sheet, after the insects are stunned we use forceps to pick up the insect and preserve it in a bottle of ethanol.  Completed the collection for the day and filled up two bottles of ethanol with a multitude of different species.

I really enjoyed learning how to use these collecting tools, there is a such an art and finesse to collecting that takes many years to master.  It turned out to be a very long day after the morning and night collecting, can’t wait for more adventures, but now to get a little shut eye.

Guest Post: Notes on mx: Lessons from Treehoppers

In response to our previous post this is a guest post from Lewis L. Deitz, Department of Entomology. North Carolina State University, Raleigh, NC. Thanks for the feedback Lew, you've set some lofty goals for us to reach! I sincerely appreciate the creation of this blog for user input. I urge other users to set aside time to share their recommendations. A great deal is outstanding about mx, even though my focus is necessarily on items that I feel might be improved. My suggestions stem from work in developing the Treehoppers Website and Database. We bulk-loaded taxon data for higher categories and genera from spreadsheets. I fear that refining these data and back-filling data that did not quite fit mx formats will require a tremendous amount of time and effort. It is my hope that the lessons learned from my experience will prove helpful to future mx projects and the development of mx/TaxonWorks.

cc0 vs. the world

Today I had some discussion that stirred up my desire to say, in a loud voice: "But look here, if it is credit you want, then the best way to get it is if your data are cc0, it's even better than cc-by!" So I tweeted: #informatics need a study. If a dataset/paper is CC0 does it increase the *citations* relative to *any* more restrictive CC (I suspect so). — Matt Yoder (@mjyoder) July 30, 2014 TL;DR There are lots of hints, but apparently no direct studies that address this. Two important bits of clarification based on my original thoughts. I was only interested in cc licensed data. I was not asking whether cc0 data is reused more than other cc- data, just whether cc0 data gets *cited* (yes, citations = bad metric, so use a generic "pointed to" perhaps) more than other cc- data, particularly cc-by. The basic premise is that the best way to (ultimately) bring focus to your work is to make it completely free, and that this will bring more attention, i

The St Croix River

Doughnut case This is the fourth in a series of posts by our intern  Jeff  Jaureguy .       Day 4 June 29, 2016         Started off another beautiful day in the amazing state of Wisconsin to a gourmet breakfast at a local cafĂ© recommended by Dr. DeWalt.  This place had an amazing assortment of delicious doughnuts and pastries, I ended up picking the freshly made apple fritters. Caddisfly           Headed out  on the St Croix River for another long field day at a site along a river which used to be an old logging camp that used the river in the 1800s for sending their logs downstream.  The place had a old cobblestone wall along the dense green forest which then led to a old water wheel further down the beaten path.  I jumped into the stream, and started sifting through the sticks and mud  looking for caddisflies, mayflies, and stoneflies to add to the sample.  Found a lot of caddisflies at this site due to being at headwaters section of the river.
