Researchers trace how birds, fish go with the flow
October 6, 2015 09:16 AM - New York University
Fish and birds, when moving in groups, could use two “gears”—one slow and another fast—in ways that conserve energy, a team of New York University researchers has concluded. Its findings offer new insights into the contours of air and water flows--knowledge that could be used to develop more energy-efficient modes of transportation.
Are fish the greatest athletes?

When you think of the world’s greatest athletes, names like Usain Bolt generally spring to mind, but scientists have discovered the best athletes could well be found in the water, covered in scales.
It turns out that fish are far more effective at delivering oxygen throughout their body than almost any other animal, giving them the athletic edge over other species.
Noise pollution harms wildlife, degrades habitats
October 5, 2015 09:11 AM - Shreya Dasgupta, MONGABAY.COM
Traffic noise is just another inconvenience for many of us. But for wildlife, noise from honking, and zooming vehicles can often be an insidious threat: it can degrade habitats without leaving any physical evidence of change, warns a recent study published in the Proceedings of the National Academy of Sciences.
Road noise — even in moderate levels — pushes migrating birds away from their stopover habitats, researchers from Boise State University in Idaho found. Those that stay back become weak.
“I was initially surprised that even moderate road noise — comparable to a suburban setting — would have such a wide-ranging impact on migrating birds,” William Laurance, a professor at James Cook University in Cairns, Australia, who was not involved in the study, told Mongabay. “On reflection, however, I guess such migrators have to be hyper-vigilent about noise, as they’re constantly moving to new areas where unseen predators could be lurking.”
Could Mealworms Help Solve our Styrofoam Waste Problem?

Plastic waste is out of control in this country, and Styrofoam is one of the worst offenders. Americans toss out 25 billion Styrofoam cups each year. Over two million tons of the stuff ends up in landfills, where it does not biodegrade. Scientists think they may have found a solution for our Styrofoam problem, though: feed it to the worms!
Loss of ocean predators has impact on climate change strategies

Continued unsustainable harvesting of large predatory fish, including the culling of sharks, can have far-reaching consequences for the way we tackle climate change.
How will offshore wind farms affect bird populations?
September 28, 2015 08:42 AM - University of Leeds
Offshore wind farms which are to be built in waters around the UK could pose a greater threat to protected populations of gannets than previously thought, research led by the University of Leeds says.
It was previously thought that gannets, which breed in the UK between April and September each year, generally flew well below the minimum height of 22 metres above sea level swept by the blades of offshore wind turbines.
Horse Owners Can Manage Flies with Wasps
September 25, 2015 09:49 AM - Entomological Society of America
Horses need help when it comes to insect pests like flies. But, unfortunately, horse owners are in the dark about how best to manage flies because research just hasn't been done, according to a new overview of equine fly management in the latest issue of the Journal of Integrated Pest Management, an open-access journal that is written for farmers, ranchers, and extension professionals.
Nearly half of US seafood supply is wasted
September 24, 2015 03:13 PM - Johns Hopkins University Bloomberg School of Public Health
As much as 47 percent of the edible U.S. seafood supply is lost each year, mainly from consumer waste, new research from the Johns Hopkins Center for a Livable Future (CLF) suggests. The findings, published in the November issue of Global Environmental Change, come as food waste in general has been in the spotlight and concerns have been raised about the sustainability of the world’s seafood resources.
Alarming report on the health of our oceans
September 20, 2015 06:29 AM - Alicia Graef, Care2
The sheer vastness of the oceans on this planet make it seem almost impossible that our actions could bring them to the point of no return, but a new report has found that we are causing an alarming decline of marine ecosystems and the species who rely on them.
According to the World Wildlife Fund‘s (WWF) recently released Living Blue Planet Report, marine populations have declined by an astonishing 49 percent between 1970 and 2012, with with some fish species, including tuna, declining by almost 75 percent.
Birds that flock to feeders are more likely to get sick, spread disease
September 17, 2015 08:56 AM - Virginia Tech
Wild songbirds that prefer to eat at bird feeders have an increased risk of acquiring a common eye disease. In turn, these birds also spread the disease more quickly to their flock mates, according to an international research team led by Virginia Tech scientists.
