Tempe, Ariz. -- Human and natural impacts on the world's rivers are affecting their central role in supporting global fish species, U.S. researchers say.
Scientists at Arizona State University say rivers and streams around the world are being affected by human use, or drying up due to climate change, altering the natural variability of river flows, ScienceDaily.com reported.
Some rivers have dried completely and no longer run, while others are experiencing extreme variability of flows due to storm floods.
The two forces are conspiring to shorten food chains, especially by eliminating top predators like large-bodied fish, one researcher says.

Raleigh, N.C. -- In a surprise finding, U.S. researchers say fish located near coal-fired power plants have lower levels of mercury than fish that live farther away.
North Carolina State University researchers say the result may be linked to high levels of another element, selenium, found near coal-fired facilities, which can present problems of its own, a release by the school said.

Clover, S.C. -- A fishing trip brought a South Carolina man an unexpected 40th birthday present -- a fish with "teeth like a human."
Frank Yarborough, of Clover, caught the pacu, almost five pounds and 20 inches, in Lake Wylie. It's an exotic South American species related to the piranha.
"It's definitely the strangest thing I ever caught in Lake Wylie," Yarborough told the Charlotte (N.C.) Observer. "We had all kinds of people looking at it, taking pictures of it, Goggling it at the boat landing."
South Carolina state biologists measured the pacu at 4.98 pounds and 19.5 inches.
"That's the biggest one we've seen out of Lake Wylie," said Wes Stewart of the Department of Environment and Natural Resources.

Lexington, Mo. -- A kayaker in the Missouri River 340 boat race said he was hit in the face by an Asian silver carp that leaped from the water.
Brad Pennington, 43, of Houston said he was attempting to tie his kayak to a three-man canoe to receive help repairing a damaged rudder about 11 a.m. Tuesday when he was hit in the face with what he initially believed was a brick, the Columbia Missourian reported Friday.
Pennington said the men in the canoe explained he had been hit by a 20- to 30-pound fish.
"I just went down the river laughing afterwards," said Pennington, who dropped out of the race at Lexington, Mo., due to his damaged rudder. "I got face-slapped by a flying fish."

Guelph, Ontario -- Whether a fish likes to pursue its food or wait for home delivery is linked to the structure of its brain, a Canadian researcher says.
Biology Professor Rob McLaughlin of the University of Guelph in Ontario says the foraging behavior of brook trout is related to the size of a particular region of the fish's brain, a university release reported Wednesday.
"We found that the fish that swim around in the open in search of food have larger telencephalons than the fish that sit along the shoreline and wait for food to swim by in the water column," McLaughlin said.
The telencephalon is a brain region involved with fish movement and use of space.

Boston -- A Massachusetts company says it's close to getting federal approval to put genetically modified salmon on the market.
AquaBounty says it intends to market an "advanced hybrid" of a fast-growing Atlantic salmon that has been genetically altered with help from a Pacific Chinook salmon, McClatchy Newspapers reported Sunday.
AquaBounty's fish don't grow bigger than normal Atlantic salmon, but they grow faster.
The company achieves results by adding a growth hormone gene from the Chinook salmon along with an on-switch gene from the ocean pout, a distant relative of the salmon, to a normal Atlantic salmon's roughly 40,000 genes, McClatchy says.

Washington -- Two similar kinds of Canadian fish that could interbreed don't because females are looking for mates just like their own fathers, researchers say.
In several British Columbia lakes, two species of stickleback fish could easily interbreed with each other, but females are apparently only looking for mates who smell like dad, ScienceNews magazine reported Monday.
Slimmer sticklebacks who feed on plankton in open water mate with their own kind, while larger, bottom-feeding sticklebacks mate with theirs, says Genevieve Kozak of the University of Wisconsin-Madison.
Experiments show that early in life, females of both varieties pick up some cue from their fathers, probably an odor, that comes into play when choosing a mate, Kozak says.

Heidelberg, N.Y. -- British scientists have built a computer-controlled robotic fish they say is revealing clues to the behavior of animals in moving groups.
"Robofish," developed by researchers at Britain's University of Leeds, can "recruit" and lead living fish in a tank to shed light on what makes fish in a shoal change directions, an article in the journal Behavioral Ecology and Sociobiology reported Tuesday.
Placed in a tank with live fish, Robofish, a replica stickleback, encouraged both single fish and groups of up to 10 to follow it, and was able to make groups turn in the same direction as itself, demonstrating the effect of a leader fish on shoal behavior, the article said.
