Flooding has forced me into upland streams for sampling and I either experienced no fish (such as catching just bugs further up Martin Brook) or seeing very fish but not really catching any. (seeing two small fish but only getting crayfish further up Roaring Brook, seeing a trout in a river in the White Mountains but only seeing a few and getting a sucker in a pond.)
this combined with North Carolina being chosen for the convention based on diversity alone, and me being annoyed that even in normal lowland areas small streams often have fish free stretches in New England while streams in New York, Ohio, and Virginia team with fish in every niche, had got me thinking like this. "Ten thousand years separated from, other waters like an island since the ice age and the ONLY evolution New England had was two Lacustrine trout. Where is the adaptation to new niches and unique island evolution".
This line of thinking collided with the lake dwelling rainbow darter article and an odd realization hit me.
look at the northern subspecies and species that evolved in post glacial areas,
SUNAPEE TROUT: lake/pond adapted (but as a varient of the blueback strain of arctic char which is stream dwelling it may not count)
SILVER TROUT: lake/pond adapted
SUMMER SUCKER: stream adapted
BLUE PIKE: lake/pond adapted
PHALEN RAINBOW DARTER: lake/pond adapted
BANFF LONGNOSE DACE: lake/pond adapted
NOOKSACK DACE: stream adapted
Even if you ignore the Sunapee for sharing subspecies with the blueback the list leans to lake adapted fish, Is this flawed from a small sample size, or are fish more inclined to evolve to lake adapted species in post glacial areas.
(the sad thing is, of this list three are now extinct and a couple are barely hanging by a thread)
