Moths Survive Bat Predation Through Acoustic Camouflage Fur

Acoustical Society of America (ASA)

Moths are a mainstay food source for bats, which use echolocation to hunt their prey. Scientists are studying how moths have evolved passive defenses over millions of years to resist their primary predators. While some moths have evolved ears that detect the ultrasonic calls of bats, many types of moths remain deaf. In those moths, researchers have found that the insects developed types of “stealth coating” that serve as acoustic camouflage to evade hungry bats. Neil will describe his work during the Acoustical Society of America's 176th Meeting, Nov. 5-9.

Tropical mountain species in the crosshairs of climate change

Cornell University

Lack of varied seasons and temperatures in tropical mountains have led to species that are highly adapted to their narrow niches, creating the right conditions for new species to arise in these areas, according to a new study published in the Proceedings of the National Academy of Sciences. Still, the same traits that make tropical mountains among the most biodiverse ecosystems on Earth also make the species that live there more vulnerable to rapid climate changes, the study finds.

Identifying a Piranha by Its Bark

Acoustical Society of America (ASA)

Next month, Rodney Rountree, “The Fish Listener,” will talk about his work with Francis Juanes of the University of Victoria, to document calls made by fish in the Pacaya-Samiria National Reserve in Peru in a presentation at the Acoustical Society of America's 176th Meeting, Nov. 5-9. These calls may be useful for tracking piranha populations through passive acoustic monitoring.

How to Reduce the Impact of Shipping Vessel Noise on Fish? Slow Them Down

Acoustical Society of America (ASA)

One concern with the increase vessel transits in the western Canadian Arctic is how noise pollution can detrimentally affect marine animals -- including Arctic cod -- given the critical importance of these fish in the arctic food web. Researchers at the University of Victoria, WCS Canada and JASCO Applied Sciences have found that the negative impact of noise from shipping vessels can be mitigated by reducing the ship's speed. They will present their research at the Acoustical Society of America's 176th Meeting, Nov. 5-9.

As Evening Commute Gets Darker, It Could Also Become More Dangerous

Cedars-Sinai

The end of daylight saving time—on Nov.4 this year—could create a more dangerous evening commute for people on foot, as darkness falls earlier and drivers find it harder to see on the road, says a Cedars-Sinai trauma physician.

Racial, ethnic minorities face greater vulnerability to wildfires

University of Washington

Massive wildfires, which may be getting more intense due to climate change and a long history of fire-suppression policies, have strikingly unequal effects on minority communities, a new study shows.

How one tough shrub could help fight hunger in Africa

Ohio State University

The trick to boosting crops in drought-prone, food-insecure areas of West Africa could be a ubiquitous native shrub that persists in the toughest of growing conditions. Growing these shrubs side-by-side with the food crop millet increased millet production by more than 900 percent.
