Thank you for such an in depth letter and requesting references. There is package of them i will collect from my files and post later today, maybe even tonight. Some going from this week to over a decade ago.I'm not sure why this is in a thread which should be titled, " There are too many GD wolves in Idaho..." The thread is about the political ramifications of Idaho reducing wolf populations below 500.
Your post does prove the point that whenever there is a thread about predators, the usual suspects will post their usual convictions, myself included. More evidence that not one real problem has ever been solved on social media.
If you are going to wave the "studies" flag, please be a sport and actually cite the studies. Otherwise you are making gratuitous assertions.
I assume you mean this study comparing infection rates of lion killed deer to infection rates in human killed deer (including road killed). The authors make no claims regarding the effects, good or bad, on CWD transmission. They begin with the hypothesis that predators select for easier kills, collect data and make observations.
Mountain lions prey selectively on prion-infected mule deer
The possibility that predators choose prey selectively based on age or condition has been suggested but rarely tested. We examined whether mountain lions (Puma concolor) selectively prey upon mule deer (Odocoileus hemionus) infected with chronic wasting ...www.ncbi.nlm.nih.gov
It seems (to me) you are projecting conclusions which the authors are careful NOT to make.
The paper's concluding paragraph notes: (emphasis added)
"We observed that mountain lions typically consumed greater than 85 percent of a deer carcass, often including brain tissue, and this may be beneficial in decreasing prion contamination at kill sites. However, the extent to which selective predation by mountain lions alters the dynamics of prion disease epidemics in natural mule deer populations remains unclear (Miller et al. 2008)."
Although the logistics would seem impossible, I would be interested in a follow-on study of prion prevalence in lion scat within x km radius of kill sites.
My file can be a bit overwhelming
I do not create theories myself, I just read/study a lot feeding my interests as both a life long hunter and retired biology educator.
Without question there is a split within the world of field biologists too.
Many have a lifetime invested in working for Fish and Game Departments where keeping the money flowing in from tags sales has been the general theme.
More recently there is a trend towards integrating Hunting, with health/disease issues that can effect both people and wildlife.
This is being reflected in who is being placed on fish and game commissions in different states depending on ideological leans
Later then
