The following thought provoking and interesting article is from The Wolf Conservation Face Book page. This has been touched on before on this website but any further comments on this?
A gray wolf is dead in Oregon, and people may be to blame.
The animal had been trapped by federal biologists in October and fitted with a radio-tracking collar that reported on its movements. Just over a month later, the wolf was dead. Given that a baited leg-hold trap was used to catch the wolf, it’s possible that the capture contributed to the wolf’s demise, officials said. http://bit.ly/2NZkRCj
The stress of capture itself — from being immobilized in a trap, or chased over long distances — can kill.
This kind of death is caused by a condition called capture myopathy, which occurs when overworked skeletal muscles — the ones that power the fight-or-flight response — start to break down and release a hormone called myoglobin. In great amounts, myoglobin can enter the bloodstream and concentrate in the kidneys, where it causes tissue damage and sometimes kidney failure.
“An individual animal is never better off because we trapped it or caught it or tagged it,” said Steven Cooke, a biologist at Carleton University in Canada. “But the knowledge gained from that individual can hopefully be useful for informing how to better manage, conserve, protect and restore populations and species.”
Does the potential knowledge gained from collaring an animal outweigh the negative impact the capture process has on the animal? What say you?
