Yeah, there are lots of dragonfly species, and you are certainly welcome for the links.
In the reports do they indicate/note which lakes have the greates preponderance/biomass/i.e. most feed of these bugs?
The report from ECY doesn't address the biotic survey at all, because it was prepared before EPA finished performing the biotic analysis. As to whether or not some calculation of biotic mass is included in the EPA database, I don't really know, as I was given only what I requested, and didn't request that.
Well why the hell not!
Just kidding, but it seams like a useful bit of info to have.
Roger, I've reflected several times on how much more efficient today's computers make research. Back in the day we gathered the data, recorded it on forms, usually using pencil on waterproof paper since it was always wet where we were working. We then gave the data to a key punch specialist who would punch it onto cards. The cards were then given to a computer specialist to run through computers that took up half of a room and chugged out reams of paper which then had to be read, analyzed and interpreted. Then the writing started, usually longhand to start. Then it was retyped with something called a typewriter, no internal or disc storage either, so you had to keep a second copy somewhere. Then it was edited, re-typed and submitted for review. After review it was re-typed and submitted to whomever needed it. Yeah, scientific research is definitely easier with computers. But you still have to identify and verify all of those tiny, little critters one by one...ugh. I never was much of a taxonomist, there's just two types of inverts: those that make good fish food and those that don't. You guys with the attention for detail have all of my respect.
Yes Karl, I certainly agree with everything you just said. As you likely realize, my comments on #15 concerning use of the PC were intended as tongue-in-cheek humor.
Hey Roger, it was tongue-in-cheek, well done. I get to remembering and then am totally amazed at technology now. What a gift.
Roger: this is a great thread. Thanks so much sharing your wisdom.
You are certainly welcome, Don; it's my pleasure.
Nice website! thanks for posting the information. Now I'll need to see if there is something similar for AK!
You are welcome, Stan. Good luck.
I may have used steak and M and Ms but the point is the same. More I was refering to the size of bugs that fish will eat but then again quantity as well.
Numbers aside what about mass? Will midges still "out weigh" the competition?
Have now developed a query to display individual lake survey results.
It is called WA Lakes Biotic Survey.
That is very useful Taxon, for the fly fisherman at least. Grimes as an example. SCUDS.
I did not see the sample date for each lake. Would the sampling date change the survey results? Either way, Thank you.
In the case of Grimes Lake, all sampling took place on 08/16/2007. For other lakes, sampling also took place during the summer (July, August, or September) of 2007. However, had the sampling taken place during different seasons (spring, summer, fall, winter), I would expect the results to differ based on the sampling date.
