Noise pollution causes chronic stress in birds, with health consequences for young
Noise pollution causes chronic stress in birds, with health consequences for young. Birds exposed to the persistent noise of natural gas compressors show symptoms remarkably similar to those in humans suffering from post-traumatic stress disorder, new research shows.
Ship noise affects ability of marine species to communicate
Ship noise affects ability of marine species to communicate. Every time a vessel passed within 10km (6.214 miles) of a listening station, it reduced communication space for bigeyes by up to 61.5 percent and by up to 87.4 percent for Bryde's whales. Research has shown bigeyes can communicate over distances of up to 31 metres, so a passing ship will reduce this to less than 12 metres.
Walls are more effective than plants for blocking noise, but plants provide other benefits like cleaning the air. Evergreen shrubs make the best plants for noise because they provide year-round noise reduction. Broadleaf evergreens are more effective than narrow-leaf plants and conifers. Choose trees and shrubs with dense branches that reach all the way to the ground. Plants, such as hollies and junipers, that have thick branches at ground level provide excellent noise reduction.
Bulgaria: Sofia goes green with grass tram lines
Bulgaria's capital is grassing over some of its tram lines as part of a programme to make the city greener. An initial 60m (197ft) stretch of the "green rails" has already opened in Sofia's Ruski Pametnik Square. Architects hope the new turf will muffle traffic noise, improve air quality and cool the often torrid Sofia summer heat, Nova TV reports. A drainage system has been installed to divert rain water off the rails into the soil beneath the grass.
Can Plants Hear?
Can Plants Hear? Flora may be able to detect the sounds of flowing water or munching insects. This research raises questions about whether acoustic pollution affects plants as well as animals, Gagliano observes: “Noise could block information channels between plants, for example, when they need to warn each other of insects.”
Researchers prove cormorants can hear under water
It makes good sense that cormorants can hear underwater—the environment where it finds most of its food. About every tenth bird species in the world—around 800 species—hunts underwater, and it may turn out that others can also hear underwater. Man-made sounds can disturb the ocean's animals to such an extent that they cannot find food or communicate with each other. It is a known problem for porpoises and seals for instance, and now it is also a potential problem for birds.
Why Do Elephants Hate Drones?
Elephants react negatively to research drones, which may remind them of bees. The elephants noticed the drones, which hovered anywhere from 25 feet to 300 feet above them. And it wasn’t just that the elephants noticed them; in many cases, the elephants were clearly agitated. Some of them took off running. In at least one case, an elephant used her trunk to hurl mud in the drone’s direction. “She had her baby with her,” said Missy Cummings, the director of Duke’s Robotics Lab. The elephants reac
'Sound' research shows slower boats may cause manatees more harm than good
'Sound' research shows slower boats may cause manatees more harm than good. They can't hear the motors so they get hit. "The increase in multiple propeller and boat scar patterns we are seeing on surviving animals is consistent with the implementation of slow speed zones in their habitats," said Edmund Gerstein. "Today, we have living manatees that have been hit dozens of times some with as much as 50 different scar patterns from boat encounters."
