Africa-Press – Rwanda. <\/strong><\/span>Researchers found that despite increasing the volume and duration of their underwater whistles, dolphins\u2019 ability to successfully communicate dropped by almost half at the highest audial distraction levels.<\/p>\n

Dolphins are forced to \u201cshout\u201d and adopt other strategies to compensate for man-made noise caused by drilling, hipping and military activities, a new study has found.<\/p>\n

Dolphins tasked with pressing a button within one second of a partner across a small lagoon \u201cincreased the level of their whistles in noise, nearly doubled whistle duration, and oriented more toward their partner, indicating that both dolphins were actively attempting to compensate for noise to continue communicating with each other,\u201d researchers reported in a study published in Current Biology on Thursday.<\/p>\n

But while the sea mammals have developed multiple methods of dealing with loud environments, they are apparently far from perfect.<\/p>\n

\u201cWe found that the dolphin [pair\u2019s] success rate in the cooperative task decreased with increasing levels of anthropogenic noise, irrespective of their attempts to compensate by producing louder and longer duration whistles and by changing their physical behavior to allow for better monitoring of their partner,\u201d the researchers wrote.<\/p>\n

\u201cCooperative task success decreased in the presence of noise, dropping from 85% during ambient noise control trials to 62.5% during the highest noise exposure.\u201d<\/p>\n

Noise pollution has emerged as a major issue for marine life, especially animals like dolphins that rely on echolocation to locate and track food sources. Scientists have linked the surge in oceanic background noise with an uptick in strandings, changes in behavior, and decompression sickness among cetaceans.<\/p>\n

\u201cIf groups of animals in the wild are, for example, less efficient at foraging cooperatively, then this will negatively impact individual health, which ultimately impacts population health,\u201d said Stephanie King, one of the study\u2019s co-authors and associate professor at University of Bristol, said.<\/p>\n

Their co-author, Pernille S\u00f8rensen, reportedly explained that the \u201csame reasons that make sound so advantageous for animals to use also make them susceptible to disturbance from noise in the environment.\u201d<\/p>\n

The researchers claim the study is the first to \u201cshow how increasing levels of anthropogenic noise negatively impact coordination between conspecifics performing a cooperative task\u201d in any non-human species.<\/b><\/p>\n
