Singing duets helps sperm whales to bond

Sperm whales may take as much pleasure in singing well-timed duets as humans do.

New underwater recordings have shown that the whales carefully coordinate their song to match the calls of their singing partner. The animals appear to enjoy singing to each other, possibly to strengthen relationships among females within the group.

Till now biologists had assumed that the sounds with which whales communicate are mainly intended to scout out other members of their group. But humpback males are thought to woo females with solo love songs, and male killer whales whistle to each other, perhaps to help social bonding.


US: 40,000 still lack power after Northeast storm

Albany, NY - Thousands of utility customers around the Northeast awoke without power Wednesday, a day after the season's first big snowstorm blew through the region.

The wet snow fell on trees still covered in fall leaves, and its weight, combined with gusty wind, sent limbs crashing down on power lines.

The National Weather Service said snowfall totals by Wednesday morning could range from a few inches in areas south of Buffalo and around Albany to 8 to 12 inches in the Adirondacks and the Tug Hill Plateau north of Syracuse.

In upstate New York, more than 40,000 customers remained without power early Wednesday, most of them in the Mohawk Valley, Adirondacks and the Catskills, according to statements by utilities National Grid and New York State Electric & Gas.

Pakistan 6.4 Earthquake Kills 31

Islamabad - A strong earthquake struck parts of southwestern Pakistan early Wednesday, killing at least 31 people, officials said.

The quake struck just after 4 a.m. in Baluchistan, an impoverished province bordering Afghanistan. It had a preliminary magnitude of 6.4, the United States Geological Survey reported.

The province's police chief, Asif Nawaz Khos, said at least 31 people had been killed, and a local mayor said many houses were damaged.

The quake was centered about 400 miles southwest of the capital, Islamabad.


Salmon tracked to aid conservation

Oslo - Hi-tech devices tracked two small salmon on a 2,500 km (1,550 mile) swim from the Rocky Mountains to Alaska in a step toward understanding fish migrations and protecting stocks, scientists said.

The two salmon, about 14 cm (5.5 inches) long and with almond-sized implants, swam down a tributary of the Columbia River in Idaho into the Pacific Ocean and north past a string of electronic listening devices during a three-month trip.

"We've demonstrated the ability to track animals about the size of a hot dog," Jim Bolger, executive director of the Pacific Ocean Shelf Tracking (POST) project, told Reuters. The fish swam the same distance as from Moscow to London.

"We're demonstrating the use of this array to see what's happening in the oceans. Previously we've been searching with a flashlight -- now we feel we are turning on the lights."


Scientists urge ban on catching Atlantic sharks

Washington - An international team of scientists wants to ban the catching of eight species of Atlantic Ocean sharks and put a strict limit on the catch of two others to try to prevent population crashes.

Sharks are particularly vulnerable to overfishing because they reproduce and grow slowly, but there are currently no international limits on shark catch, according to the non-profit Lenfest Ocean Program, which convened a meeting of shark experts to study the problem.

The group found in a study released on Monday that 10 species of Atlantic sharks are at serious risk of being overfished.

"Our results show very clearly that there is a critical need to take management action to prevent shark population depletion and maintain ecosystem function," said lead author Colin Simpfendorfer of Australia's James Cook University.


Snakes, Salamanders And Other Creatures Thrive In Areas With Higher Deer Populations

Reducing the number of deer in forests and parks may unexpectedly reduce the number of reptiles, amphibians and insects in that area, new research suggests. A recent study by researchers at Ohio State University and National Park Service found that higher deer activity is modifying forest ecosystems in unexpected ways. Out of several species of snakes, salamanders, and invertebrates studied, a greater diversity of animals were found in areas with deer populations than were in areas with no deer activity.

Hellbenders are the third largest aquatic salamander in the world, weighing 3 to 5 pounds on average.

The study, which comes at a time when many states have begun to selectively control deer populations, challenges previous research that has suggested deer populations can negatively impact forest ecosystems through eating plants that many smaller animals may depend on.

Instead, researchers found that high numbers of deer may in fact be attracting a greater number of species. This may be because their waste creates a more nutrient-rich soil and as a result, areas with deer draw higher numbers of insects and other invertebrates. These insects then attract larger predators which thrive on insect lava such as salamanders, and the salamanders in turn attract even larger predators such as snakes.


UK Weather - Snow and Ice in October, the Shape of Things to Come?

Widespread frosts and ice, snow showers, sub zero temperatures and winds direct from the arctic aren't things normally associated with mid Autumn, but this week they're all going to be mentioned within weather forecasts for the UK.

Is this the shape of things to come for the rest of Autumn and into Winter though? Forecasters at think it may be, as they expect a November with temperatures to be close to or below the average with the start of Winter following a similar vein.
