That makes me sick! Youtube should yank those, and I complained to their management. If you are in those videos Hotdogs, you should really think about you're legacy.
You have a hog problem yet you disagree with the facts of their biology and ability?
Did you notice the state biologist that spoke several times?
I mainly meant the speed of all feral hogs and growth potential of all feral hogs in general...You have a hog problem yet you disagree with the facts of their biology and ability?
While you bring up a good point I will address next, this statement was aimed at the poster who took it upon himself to assume these were homemade vids rather than professionally made discovery channel film.Did you notice the state biologist that spoke several times?
Body shape aside, one give away is the coloration. the blond chin bar is one aspect that is breed specific as is the white band of the Hampshire or bright red of the duroc.... Another eur-asian (russian) trait is the pronounced high humped back above the shoulders...I noticed the biologist. I also noticed the geneticist. She specifically stated that she didn't have the evidence to substantiate the claim the Russian boar connection. So much of the show was dedicated to saying that the changes in pigs were due to interbreeding with Russian boars and yet that absolute proof for this, the genetics, simply are not there...not yet anyway.
Hogs in feral state need only several generations to adapt pysically to their surroundings and survival needs. The longer legs, narrower body and long snout is present very soon as it aids travel and the long snout aids in rooting food. A barnyard hog develops shorter legs and wider body as well as short snout and wide head to take up more space at the feed trough. Feral hogs will revert to barnyard shape in just a few generations of being re-domesticated.Yes, we do have hogs that resemble Russian boars. What was not considered in the show was if the similar characteristics discussed were a matter of genetic influx or evolutionary pressures. What pigs are most likely to survive and reproduce most successfully in the wild? Are they the shorter legged, shorter snouted, less aggressive, smaller pigs? Probably not. Those are the pigs likely being selected against, biologically speaking.
I not only took note of the game cam picture but all the hogs being cared for to preserve the specie in the minutes leading up to that point. I also noted the characteristics like coloration and the high humped back. the extra hairy body may or may not be climate adaptation as all feral swine is far hairier than the domestic raised hogs.Did you notice how they identified a Russian boar on the game camera? That was one hell of an identification. They didn't get anything but eye shine. So you can't even identify the type of animal in the image, but they were able to identify it as a specific breed and noted features not in evidence such as long legs, long snout, weight, head size, etc. That isn't biology. That isn't good biology in the least.
since there are no natural predators of feral hogs other than humans and they seem to be immune to even the most venomous snakes (they routinely eat rattlers) it is quite realistic. It is also true, plausible and expected for a sow to drop 18 pigs ever 14 months on average (not maximum) it is really an issue. Even with all the hog hunters in my area, we do not ever seem to reduce the numbers and there has never been much importation of any numbers of feral hogs of any breed since the spanish explorers....The show also claimed that as a worst case scenario that the pig population could double every few months. Mathematically, that may be true, but then again, that isn't reality and so they are making a considerable sensationalized claim.
taken in verbatim context you are correct but if you realize that what wasn't said is there are no INVASIVE species with ZERO natural predators that are of this "R selection" type breeding at this rate. Rats, mice, rabbits, coons and possum all have a decent level of predation keeping their numbers in check... So they really are very unique...Strangely, the biologist noted that pigs can breed as early as 5 months of age and sows can produce 3 litters of an average of 6 young per litter ever 14 months and that there is nothing else out there that can keep up with that. What he is saying is that pigs have an "r selection" reproductive pattern (e.g., multiple large litters per year vs. K selected species that tend to produce smaller litters less frequently such as deer, for example). So while K selected species don't reproduce anywhere near as fast as hogs, there are many r selected species that reproduce as fast or faster than hogs. So, there are definitely other animals that can keep up with or surpass pig reproduction success. So the worst case scenario for a lot of animal populations would have them breeding at rates much faster than hogs, mathematically speaking. In this regard, hogs are not unique.
That is auto-answered if you realize that hogs don't have to swim from russia/asia to reach the "old world" of western europe. And the same "noble types" that introduced alot of russian blood to the eastern USA (the Metcalfs and Rockefellers come to mind here) in the early 20th century were of the same high brow society that were "royalty" that imported russian hogs from their home territory to the western european country side for the "sportsmen" of their time in the 1800's and/or before...I also noted how the show seemed to correlate the Pig Bomb in the US as being due to the influx of Russian boar genes into the non-Russian feral hog gene pool in recent years. Strangely, it was noted that there was a pig bomb phenomenon in the Old World as well. What influx of genetic material is being introduced there to cause their pig population explosion to co-occur with the one in the US?
I will say that many areas of feral hog population have less of the russian type traits and more of the domestic breed traits. Both physical form and coloration as well as aggressive or passive behaviors. Some areas really show the breed specific coloration of their original preferred barnyard stock.So do I doubt the biology? That depends what you are asking. I doubt the biology expressed in the show that seemed to play up a lot of pseudo facts and innuendo that just don't have the biology behind them to be considered a valid claim. In short, they sensationalized the information considerably.
We also have the "hybrid tooth"...
