Land-based wind farms have been found to have a much larger and more complex impact on the ecosystem than simply dealing with birds or bats. United Nations News
Wind energy is the fastest growing source of renewable energy in the world. The total area of wind generators in the world is 17 million km, which is 1.7 times that of South Korea.
As terrestrial wind energy increases, the impacts on the ecosystem are worrisome. It's mostly birds, bats and other animals that are dying from windmills. It has also been reported that the migratory bird flyway is changing or that the density and activity of terrestrial mammals in the vicinity of wind farms is decreasing. However, it is still unclear what effect the diet net of the ecosystem has on the whole.
Indian and American researchers have reported on the indirect effects of wind energy on ecosystems in the Sogot region, a global report on biodiversity presented by India 16 to 20 years after the introduction of the wind farm, in a recent issue of Nature, "Nature Ecology and Evolution".
The Sogol region in southwestern India is a global hotspot for biodiversity. The appearance of a wind farm in this place. Maria Taeker and her collaborators (2018) provided "The Ecology of Nature and its Evolution".
A contrast zone where the Sogotto wind turbines are not entered. Maria Taeker and her collaborators (2018) provided "The Ecology of Nature and its Evolution".
Where there are wind farms, there are fewer raptors such as buzzards, snakes and kites. The researchers said that in places without wind turbines, raptors plummeted and attacked their food four times more often. Raptors are met in windmills and die or avoid the place.
When predators have bandaged their changes, their endemic lizards, their main prey, have changed. It has been reported that mechanical noise in terrestrial mammals living near wind farms has increased the secretion of stress hormones. However, unlike the local lizard, the secretion of corticosterone, a stress hormone, has decreased. The researchers badyzed that "the pressure had been reduced". Indeed, here, the lizard was five times shorter than the area without wind farms to allow people access until the moment of their flight. It is in this region that people often go for livestock and crops, but lizards have become physiologically relaxed as predators decline.
The researchers said in an article that "the influence of edible pressure on the nets of the ecosystem is changing unexpectedly and complex, as well as on behavior, physiology, the wind turbine is" an excuse for add a new top predator to an existing food web ".
The native lizard, the main food of the raptors of the Segoth region. Has a colorful decoration on the chin. Maria Taeker and her collaborators (2018) provided "The Ecology of Nature and its Evolution".
So, have the windmills reduced prey, raptors and life of the lizard, the main food? The results were the opposite. The lizard near the central was rather dry than in the region without. The predator tripled the density of the ribbon lizard, which reduced the amount of arthropods that lizards could eat.
The lizard has a jaw colored blue, black, orange under the neck to defeat rivals and buy women's favors. But the lizard males where the wind power plant is located were less bright and lighter than the blue and orange jaw light. It is a fatal weakness of badual selection. The researchers badyzed that "as the number of lizards was so high that competition was fierce, it was difficult to find beetles with many carotenoid pigments to decorate their jaws."
The production of wind energy is more natural than the production of energy using fossil fuels and disrupts less habitat. The researchers however pointed out that the impact of wind energy could be much greater in a single or very diverse ecosystem.
"Humans have ruled the Earth as a" super predator "that has overcome the fear they have caused by removing animals (predators) .This study shows that even though people do not show up directly , an artificial disturbance such as a wind turbine can be an effective upper predator. "
