Many scorpions are living in arid Australia – an unexpected consequence of the extinction of a species like Bilby – researchers have suggested bringing back endangered predators to restore the damaged ecosystem.
Researchers at the University of La Trobe have found that the key to reducing the scorpion population is the key to regenerating native animals, such as bilbiz.
The arrival of Europeans in Australia introduced predators such as feral cats and foxes, causing large-scale damage to native mammal species.
Research published Ecology, The number of scorpions is submerged in the presence of native mammals.
The team also observed a decline in scorpions while mimicking the miserly actions of soil-muttering native mammals.
Mammals reduce the number of people in other rectum, such as spiders.
Thus, reproducing locally endangered digging mammals may be involved in repairing ecological damage.
Researchers led by Associate Professor Hallows Gibb found about 600 scorpions per hectare in the mammal-free section of the Australian Wildlife Conservation Scotia Sanctuary in West New South Wales.
This raises the question: “Were they always so numerous or could the excess of these scorpions be the result of the removal of other species from the ecosystem?” Dr. Gibb says.

“Large native scorpions of nine centimeters in length are indeed abundant in the male and they play a large role as predators of other smaller, species.”
Malle in northwestern Victoria may seem “extremely harsh and even lifeless” in the summer, but it usually comes with nocturnal zebras, spiders and other nocturnal animals.
Dr. Gibb and the team used UV-proof goggles and a UV torch to hunt scorpions in the dark on the hottest night of summer.
“You won’t see much at night with UV-proof glasses. However, in the light of our UV torch, the scorpions fluoresce – so all you can see is scorpions. We used tongs to raise their tails to measure, because these scorpions are big and no one wants to be punished. “
Researchers do not know what Australian ecosystems were like 200 years ago, but Dr Gibb says reproducing locally endangered mammals is “hard to find properly”.
“It is important to consider that reconstruction may have unintended consequences for the structure of the ecosystem.”
“Over-predation of one species may increase among others and cascade these changes from predators to plants in all ways.”
