which often grows along the banks of rivers and streams is a convenient snack for kayakers and a staple in the autumn diets of many country dwellers.

The rivers there often have warm springs that help maintain open water in winter which helps the owls to hunt their prey.

We are often walking along frozen rivers during the day inching up fairly close to the lip of open water patches to look for owl tracks.

The rivers are not usually very deep but it's always an unpleasant experience. At night the team settles into a concealed tent near a foraging spot to monitor the owls'hunting behaviors.

#Intersex Fish Showing Up in Pennsylvania Rivers Editor's Note: This story was updated on Tuesday (July 1) at 10:25 a m. E t. Scientists found intersex fish in three river basins in Pennsylvania a sign that the water may be tainted with chemicals from human activity.

Male smallmouth bass with female characteristics namely immature egg cells in their testes were discovered in the drainage areas of the Susquehanna Delaware

and Ohio rivers according to a new study led by the U s. Geological Survey (USGS). Such abnormalities are linked to estrogen-mimicking chemicals

which likely got into rivers and streams from agricultural runoff and human waste the researchers said. 12 Worst Hormone-Disrupting Chemicals

& Their Health Effects The sources of estrogenic chemicals are most likely complex mixtures from both agricultural sources such as animal wastes pesticides

Researchers with the USGS previously found intersex smallmouth bass in the Potomac river Basin similarly linked to endocrine-disrupting chemicals or EDCS.

For the new study Blazer and colleagues collected fish from 16 sites in the Susquehanna Delaware and Ohio river basins.

River and streams funneled the mercury to the bay. It's a massive undertaking that's going to lead to some pretty significant changes in the environment

#Man-made Flood Could Help Revive Colorado river Wetlands An artificial flood could surge down a dry riverbed from the United states into Mexico either this spring

and store water but it also permitted an experiment to send a pulse of 34 billion gallons (130 billion liters) of water coursing down the Mexican extent of the Colorado river a stretch drained dry by overuse upstream

in the United states. This could mark a new era of collaboration among users of the river's water one that benefits the environment said Karl Flessa a conservation biologist at the University of Arizona in Tucson

Decades of dams and diversions The Colorado river system is among the most extensively dammed diverted and regulated rivers On earth Flessa noted.

Only about 10 percent of the Colorado river Delta's original wetland and riverbank areas now remain with less than 3 percent of the native cottonwood

In the mid-1980s scientists noted that accidental releases of water into the Colorado river Delta

Then in the 1990s floods in both the Colorado river and Gila river (a tributary of the Colorado river) delivered more than 2. 4 trillion gallons (9. 3 trillion liters) of water into the delta in multiple pulses breathing

Researchers have generated intentionally floods before in the United states such as farther up the Colorado river in the Grand canyon last year.

They can forge rivers and lakes that are 3. 7 to 5 miles (6 to 8 km) wide according to Woodland Park Zoo.

Even Asian carp currently the most talked-about invasive species in the Midwest were ignored largely until they began to heave their bodies out of the water and lash Illinois river anglers across their startled faces.

I've rafted West virginia's Gauley River and agree with the guides who say the Gauley resembles a western river not only because of its wild whitewater

but also its coniferous forest canopy up to 50 percent of the canyon's steep slopes are covered in hemlock.

Our group was thrilled by the sight of a bald eagle flying over the river passing unnoticed by wading fishermen intent on catching trout.

As they swim they try to detect food along the muddy bottom of the river stream pond

Certain changes in dialects also occur as you move from southern China to northern China Talhelm learned with the Yangtze river acting as a dividing line.

The Yangtze it turns out is also the point at which rice farming in the South transitions to wheat farming in the North.

If you're a vegetarian tucking in along the Nile thousands of years ago would have felt just like home.

while the Nile region became increasingly arid between 3500 B c . and 600 A d. To Kate Spence an archeologist and specialist in ancient Egypt at the U k.'s University of Cambridge this could be expected:

Although the area is very arid they were cultivating crops along the river just by managing irrigation

When the level of the Nile decreased farmers just came closer to the river and kept on cultivating in the same way.

Most people would probably expect the ancient Egyptians living along the Nile to have eaten loads of fish.

If you took a cruise along the northern stretch of the Nile some 6000 years ago you wouldn't have seen any pyramids

At that time the Nile wasn't surrounded by desert; rather the warmer wetter landscape resembled the current scenery of sub-Saharan East Africa.

Most of the region's nutrients were concentrated in the Nile floodplain and competition with farmers might have also hurt herbivore populations.

Eighty percent of the planet's species died off at the end of the Cretaceous period 65.5 million years ago including most marine life in the upper ocean as well as swimmers and drifters in lakes and rivers.

The La Brea Tar Pitswere once a moist woody habitat that may have had also streams or a river she added.

Leaf matter used to construct the nest cells likely came from trees not far from the nest site suggesting the La Brea Tar pits had a nearby forest possibly containing streams or a river.

#America's Most Endangered River Is#As California's San Joaquin River meanders down from the Sierra nevada across the Central Valley toward the San francisco bay it loses water to farms and communities along the way.

Now amid drought a national river conservation agency is calling on California to manage the San Joaquin's much-needed water more efficiently.

The nonprofit American Rivers announced today (April 9) that it has deemed the San Joaquin the most endangered river in America.

The organization highlights 10 rivers each year facing threats and management decisions that could make or break their futures.

and water diversions said John Cain the conservation director for California floodplain management at American Rivers.

and quantity of the San Joaquin river Cain said. The San Joaquin and its tributaries are dammed extensively and water diversions remove 70 percent of the natural flow of the river American Rivers reports.

More than 100 miles (160 kilometers) of the river have run dry for half a century because of the diversions.

A second tipping point for the river involves attempts in Congress to overturn a settlement agreement to restore the San Joaquin.

This settlement hard-won over the course of two decades of litigation is threatened by the pressures on the river's water.

The problems have worsened only as California's drought drags on. In February the Fresno Bee newspaper reported that planned water releases for the restoration have been put on hold until at least 2015.

Water solutions The drought however is not the reason American Rivers chose to highlight the San Joaquin this year Cain said.

The river's problems run deep and would require a solution no matter how much rain California was said getting he.

American Rivers is urging Californians to push for a sustainable management plan for the San Joaquin.

See Images of the San Joaquin River Nationally citizens can urge their senators to oppose attempts to overturn state

and federal laws that safeguard rivers from excessive diversion Cain said. What we're advocating for is better water management regimes

American Rivers highlighted nine other endangered rivers in its report as well. Threats range from excessive diversions to outdated dams to polluted runoff.

which allowed crops to be grown further away from rivers and water sources. Although the role of irrigation systems in creating despotic states has been overstated in the past they certainly would have created an opportunity for would-be leaders to behave entrepreneurially by managing their construction.

Indeed the most despotic early states arose in locations such as Egypt where agriculture had to happen in a narrow valley along the Nile making dispersal very difficult.
