A troubling trend has occurred for ranchers in NE Washington … cattle are experiencing breeding issues since the migration of wolves to the area…
the rate of female cows .. that didn’t become pregnant has increased from five percent to about 20 percent. A cow must raise a calf every summer for the rancher to recoup costs …
Diamond M also has a winter range to cut costs, but when wolves came into the area about a decade ago, they’ve seen their cattle attacked…
Texas A&M University agreed with the open cow side effect from wolves, and an Eastern Oregon Agriculture Research Center study also showed wolf-caused stress in cows.
Fewer offspring means the herd will have fewer young to watch, and they can increase the per-calf protection (ie rearing investment) provided by the herd for the young.
It isn’t surprising. Stress affects amygdala, amygdala governs sex drive, and the stress hormones produced by amygdala can alter the entire biology of the animal.
But it is still interesting to see a grass eater shift reproductive strategy in this way, merely in response to the threat of predation. It makes me wonder if as things go K, ultra-leftist reproduction will drop even farther, even as K’s begin to crave the security and safety of family, and puppy-like children to fill their homes with.
Add in all the dead liberals strewn through the streets, and I wonder if there will even be any left.
The future may be even less r than we thought it would be.
Tell everyone about r/K Theory, because you will look smarter than them, and you will be
This is why I don’t sympathize with people who raise the alarm about human birth rates being below replacement-level. So long as we keep out the immigrants, a reduced population merely makes wages go up or prices go down. The only ones who lose are bankers, stock markets, and corporations.
…which of course explains a lot
extrapolate this to the changes in White reproductive rates overall as White societies have been flooded with “diver-shitty” over the last several decades.
Pretty sure genocidal (suppresses birth rate) student loans produce the same effect in humans. Here it’s called a Graduate Tax.
If men were allowed to defend their family, it would be better too.
It’s like that moment in a film. “It’s quiet, too quiet.” Humans don’t breed in those times, babies are noisy. There was a baby boom AFTER war.
I know a lot of r women are taking fertility blockers and blaming health problems, there was one in the BBC news recently with endometriosis, supposedly caused by too much estrogen and she seemed delighted to be barren, age 22. Instead they buy dogs. Sometimes the men.
