Marine experts from a University of Vermont have conducted an investigation suggesting the importance of 13 types of extraordinary whale.
The latest study believes that whales show huge positive impact on the globe’s carbon storage and has a good impact on health when it comes to fisheries.
It has to be noted that scientists and researchers in the past has suggested that whales are excessively uncommon and are least likely to have any effect on the marine, ocean environment.
The study distributed in the journal Frontiers in Ecology and the Environment declares whales as the “engineers” of the oceans and curators of the deep.
Baleen and sperm whales, known collectively as the “great whales,” include the largest animals to have ever lived on Earth. They eat many fish and invertebrates, and distribute nutrients in the ocean and their carcasses, dropping to the seafloor also provide as habitat for many species of animals.
“Among their many ecological roles, whales recycle nutrients and enhance primary productivity in areas where they feed,” said Joe Roman, who is a biologist at the University of Vermont. Whales do this by feeding at depth and releasing fecal plumes near the surface — which supports plankton growth — a remarkable process described as a “whale pump.”
He said that the ability of whales to recover can help improve predictability and stability of marine ecosystems.
“The decline in great whale numbers estimated to be at least 66 percent and perhaps as high as 90 per cent, has likely altered the structure and function of the oceans, but recovery is possible and in many cases is already underway,” Roman and his colleagues wrote in the journal.
“The continued recovery of great whales may help to buffer marine ecosystems from destabilizing stresses,” the researchers wrote. This recovered role may be especially important as climate change threatens ocean ecosystems with rising temperatures and acidification.
Modern technology like radio tagging made it possible for the scientists to study the impact of whales on the ecology. This new research could help researchers gain insights into the benefits whales accommodate marine biological ecosystem.
The ten researchers who co-authored the paper expects the study to enhance the understanding into the matter.
