hardly a cause and effect- we should ge able to see a map of cjd cases overlap with a cwd map based on cwd at a minimum since 1967 in colorado and wyoming.Originally posted by justletmein View Post
You would see the concentrations if the case

Timothy Kurt did that research at the University of California, San Diego. Kurt looked at the role played by the 210 amino acids in the prion protein to figure out why CWD is transmitted to some species and not others. He found that when a species had a different amino acid in a key location, the diseased prion wouldn’t fit neatly into the healthy prion, like a zipper with teeth that don’t fit together. This, Kurt believes, is CWD’s species barrier. The amino acid sequence differed between humans and deer at a key location. A different study showed that a macaque’s amino acids matched the deer sequence in the same spot, but not the human one.Comment

Too long to read all of that but why are their articles of wyoming and colorado having an overpopulation of elk and deer? Why are wolves introduced in Colorado to help balance the herd? Wolves are in wyoming as well.Originally posted by flounder9 View Post
CWD Deer Herd Population Declines
CWD poses a significant threat to the future of hunting in Texas. Deer population declines of 45 and 50 percent have been documented in Colorado and Wyoming. A broad infection of Texas deer populations resulting in similar population impacts would inflict severe economic damage to rural communities and could negatively impact land markets. Specifically, those landowners seeking to establish a thriving herd of deer could avoid buying in areas with confirmed CWD infections. As they do with anthrax-susceptible properties, land brokers may find it advisable to inquire about the status of CWD infections on properties that they present for sale. Prospective buyers should also investigate the status of the wildlife on prospective properties. In addition, existing landowners should monitor developments as TPWD crafts management strategies to identify and contain this deadly disease.

Colorado CWD TSE Prion Detected in 40 of 54 deer herds, 17 of 42 elk herds, and 2 of 9 moose herds
Colorado CWD figures just out; COLORADO CWD UPDATE
Notably, prevalence in the White River herd, one of the state’s largest, rose from 15.3% to 23.6%.
Prevalence increased by about 10%, to 14%, in the Uncompahgre herd, and grew from 3.5% to 8% in the Middle Park herd.
Prevalence fell from 13.6% to 6.7% in the Sweetwater herd and from 12% to 8% in the Big Thompson herd.
Parks and Wildlife has detected the disease in 40 of Colorado’s 54 deer herds, 17 of its 42 elk herds and two of its nine moose herds.
Colorado Chronic Wasting Disease Response Plan December 2018.
Executive Summary Mule deer, white-tailed deer, elk and moose are highly valued species in North America. Some of Colorado’s herds of these species are increasingly becoming infected with chronic wasting disease(CWD).
As of July 2018, at least 31 of Colorado's 54 deer herds (57%), 16 of43 elk herds (37%), and 2 of 9 moose herds (22%) are known to be infected with CWD.
Four of Colorado's 5 largest deer herds and 2 of the state’s 5 largest elk herds are infected.
Deer herds tend to be more heavily infected than elk and moose herds living in the same geographic area.
Not only are the number of infected herds increasing, the past 15 years of disease trends generally show an increase in the proportion of infected animals within herds as well.
Of most concern, greater than a 10-fold increase in CWD prevalence has been estimated in some mule deer herds since the early 2000s; CWD is now adversely affecting the performance of these herds.
snip...(the map on page 71, cwd marked in red, is shocking...tss)
Since identifying its first cases of CWD in captive deer in the 70s and finding the first wild infected deer in 1985, Wyoming has seen the disease slowly spread throughout the state. CWD has now been documented in members of the deer family in most of Wyoming’s deer hunting areas, with 20% to 40% percent of mule deer affected in some herds. A 2017 study estimated a 21% annual population decline as a result of the fatal disease.

How does CWD impact deer, elk, and moose populations?
Recent research in Wyoming has demonstrated declines in both mule and white-tailed deer populations in deer hunt area 65 due to CWD (see below for citations). These declines are in the core endemic area where prevalence is highest. In areas with lower prevalence, effects of CWD are poorly understood but are considered additive along with other factors that can negatively affect deer populations in Wyoming (i.e. habitat loss, predation, other diseases). The distribution and prevalence of CWD in Wyoming elk is less than that of deer. Currently there are no documented direct population impacts in Wyoming elk from CWD; however, research from Rocky Mountain National Park suggests that CWD could impact elk populations at higher prevalence (13%). While CWD has been found in free ranging moose, there have been few detections, and there is no evidence that CWD is currently having an impact on moose populations.
WYOMING, POWELL — Sobering news resulting from a multi-year Chronic Wasting Disease (CWD) surveillance program by the Wyoming Game and Fish Department between 2018 and 2022 shows significant increases in the fatal disease for the state’s prized mule deer and elk herds.
In one herd, the prevalence rate is calculated at 65% in mule deer bucks, and there are concerning increases in infected elk, including hunt areas popular for Big Horn Basin hunters.
The disease, which typically kills infected animals within two years after initial exposure, now occurs in 34 of Wyoming’s 37 mule deer herds, and 15 of the state’s 36 elk herd units.

Seems if you had a population decline with a scary disease decimating it, you wouldnt introduce wolves that will just expand and turn on goats and cows after elk and deer numbers get too low
Plus harsh winters and droughts affect a population and they will yoyo.
Where is the real science showing cwd is culprit? How can that be when only science has shown that deer take 18 months or better to get infected and die after exposure? Most cervids are 4 plus before even thought of cwd killing them and thats if they make it past hunters, winters, droughts, and predatorsLast edited by Beargrasstx; 04-18-2024, 11:14 AM.Comment

I don't disagree and that article definitely makes gratuitous assumptions, but you asked what the fear is, that's the fear.Originally posted by Beargrasstx View Post
Same would apply to all prions such as mad cow, but people end up with CJD from madcow. Same would have applied from Scrapies when it jumped sheep, no?Originally posted by Beargrasstx View PostLast edited by justletmein; 04-18-2024, 11:18 AM.Comment

You serious? Wolves were introduced in CO because of a ballot initiative and Denver narrowly outvoted the people with common sense. CPW didn't want wolves nor any of the biologists. They worked hard to restore the moose population and it's about to evaporate.Originally posted by Beargrasstx View PostComment

Texas TAHC TPWD Confirm 132 More Cases of CWD TSE PrP
Jumps from 663 in March, to 795 Positive In May 2024, wow!
State kills hundreds of deer at North Texas ranch, after years of legal fights BY EMILY BRINDLEY UPDATED MAY 31, 2024 10:53 AM
In a November legal filing, the state wrote that RW Trophy Ranch “now hosts the worst-ever CWD outbreak in Texas.” In a mid-March filing, the department notified the state Supreme Court that there had been 208 positive CWD cases at the ranch over the previous three years. Parks and Wildlife staff said this week that the number continued to rise, and reached 254 by Tuesday morning.
