#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.

#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.
Before the 1930s about 4. 9 trillion gallons (18.5 trillion liters) streamed from the U s.-Mexico border to the Gulf of california each year supporting numerous wetlands and a major estuary.
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
when upstream reservoirs were enlarged full significantly its wetland areas. 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
new life into riverbank vegetation. Because the floods rejuvenated these riverbank zones conservationists were hopeful that the wetlands could be restored.
The experiment the researchers plan could shed light on how the United states and Mexico could best revive the delta.
Researchers have generated intentionally floods before in the United states such as farther up the Colorado river in the Grand canyon last year.
Before & After Images: Grand canyon Flood Future effects The pulse down the Colorado would be released from Lake Mead the largest U s. reservoir formed by the Hoover dam

The only natural migrating population that still exists is a flock that spends its summers in Canada and flies down to the Texas Gulf Coast for the winter.
Today the flock has about 95 birds that spend their spring and summer in wetlands at Necedah National Wildlife Refuge and elsewhere in central Wisconsin.
Inside the C# was the Tethys Ocean and most of the rest of Earth was the Panthalassic Ocean.
Because Pangaea was so immense the interior portions of the continent had a much cooler drier climate than had existed in the Carboniferous.
Little is known about the huge Panthalassic Ocean as there is little exposed fossil evidence available. Fossils of the shallower coastal waters around the Pangaea continental shelf indicate that reefs were large and diverse ecosystems with numerous sponge

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.
Earlier this summer park officials recovered a drone that had crashed near a marina in Yellowstone Lake Bartlett said.
If you took a cruise along the northern stretch of the Nile some 6000 years ago you wouldn't have seen any pyramids
or an elephant taking a drink at the bank of the river. At that time the Nile wasn't surrounded by desert;
rather the warmer wetter landscape resembled the current scenery of sub-Saharan East Africa. Today Egypt's elephants and giraffes are extinct.
Most of the region's nutrients were concentrated in the Nile floodplain and competition with farmers might have also hurt herbivore populations.
#Dinosaur-Killing Asteroid Triggered Lethal Acid rain The oceans soured into a deadly sulfuric-acid stew after the huge asteroid impact that wiped out the dinosaurs a new study suggests.

#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.
See the 10 Most Endangered Rivers of 2014 Fork in the river There are two big legislative
This plan governs the enormous estuary that connects the San Joaquin to the Pacific the Bay Delta;
it's the largest estuary on the west coast of either North or South america said Eric Wesselman executive director of the California conservation organization Friends of the River.
The estuary is a crucial habitat for fish including the economically important Chinook salmon Wesselman who was involved not in the American Rivers report told Live Science.
The water board has the power to increase flows down the San Joaquin into the estuary improving the water and habitat quality.
Though there is pressure from agricultural interests to keep that water for irrigation environmental advocates argue that increased flows are necessary to protect both the environment and the economy.
If the estuary collapses then these fisheries collapse Wesselman said. There are also farmers near the estuary who would prefer more water get downstream Cain added.
And 23 million Californians get drinking water from the San Joaquin and south delta. Today that supply is compromised really by the low quality
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.
