Absolutely. We're sampling about every 3 weeks. I will continue this so
long as there isn't any ice and then resume at ice out. I will have "a year
in the life of a ditch" next June.
What was really neat to watch was the pools dry out this year due to lack of
rain. The homogenous (HO) sites all went dry, the heterogeneous (HT) sites
were the refugia for fish that stayed in that part of the system (a lot of
lateral movement downstream, which we'll see in the spring when everyone
comes back). Even to the extent that HO pools were cleared by great blue
heron and raccoons, while the HT pools still maintained populations of fish.
I had never thought of topography in the channel as a form of cover (nothing
overhead)! So now I get to watch who comes back and when.

Brian, that would be fantastic!
I had thought last night about looking at it from a trophic standpoint,
which would break up the minnows from the darters and suckers. May have an
omnivore score that's diverse and even between the bluntnose, fathead and
creek chubs... But if it were accumulative across trophic structure, and had
a big fat zero for benthic insectivores, it would fall behind in a site that
had an even distribution of darters.
But for now... I have to worry wether my tests are one tailed or two tailed,
wether I use the Z or the T, and what is all that ANOVA mess about anyway?
