"An annual survey of the wolf population on Isle Royale estimated there were 37 wolves on the island this past winter — the highest number since the late 1970s. But the island’s moose population — a major food source for wolves — has dropped sharply."
Gee, I wonder why?
One thing we've learned after over 70 years of studying the island is the more we know, the more we realize that we don't know. Look at the dynamics of the population levels and the other factors on the "isolated" ecosystem, not just wolf & moose. There's many other factors that effect the population levels. When an intestinal parasite nearly wiped the wolves off the island, so did the moose levels crash, but beaver came back. The moose/wolf population levels are conflicting if you use the "lots of wolves = no moose" theory.
There's things so small we can't see, or other seemingly minor things that we refuse/ignore that effect the ecosystem way more than we know. It's just not that simple.....lol
The studies by the real biologists that haven't picked a pro/anti wolf side have noted this from YNP to BNP. There's just not enough money to complete detailed studies on this. The money goes to anti/pro wolf because it's cool. And if the study doesn't fit the funders agenda, it gets cut. Not too many can afford to just tell the truth nowadays.......just like our news media.......lol
We all know that nature likes extremes, not harmony and balance. People hate change, but it's the only thing that's inevitable.
