USA Bisons im Yellowstone-Nationalpark. Der Amerikanische Bison ist ein beeindruckendes Geschöpf. Umhüllt von dichtem braunen Fell. Vor Jahren fast ausgerottet, hat sich die Zahl der Bisons in den USA und Kanada wieder akklimatisiert. Heute leben wieder einige tausend Tiere in. Rund um den Yellowstone Nationalpark leben etwa Bisons. Weil die Tiere aber zunehmend aus dem Park drängen und Rinder.

Small populations of bison are at considerably larger risk due to their decreased gene pool and are susceptible to catastrophic events more so than larger herds.
Females give birth to one calf after a nine-month pregnancy. Bison once covered the Great Plains and much of North America, and were critically important to Plains Indian societies.
During the 19th century, settlers killed some 50 million bison for food, sport, and to deprive Native Americans of their most important natural asset.
The once enormous herds were reduced to only a few hundred animals. Today, bison numbers have rebounded somewhat, and about , bison live on preserves and ranches where they are raised for their meat.
The Census of Agriculture reported the Canadian herd at , head, a Alberta was the province with the largest herd, accounting for The next-largest herds were in Saskatchewan The main producing regions were in the northern parts of the Canadian prairies , specifically in the parkland belt , with the Peace River region shared between Alberta and British Columbia being the most important cluster, accounting for A proposal known as Buffalo Commons has been suggested by a handful of academics and policymakers to restore large parts of the drier portion of the Great Plains to native prairie grazed by bison.
Proponents argue that current agricultural use of the shortgrass prairie is not sustainable , pointing to periodic disasters, including the Dust Bowl , and continuing significant human population loss over the last 60 years.
However, this plan is opposed by some who live in the areas in question. A major problem that bison face today is a lack of genetic diversity due to the population bottleneck the species experienced during its near-extinction event.
Another genetic issue is the entry of genes from domestic cattle into the bison population, through hybridization.
Officially, the "American buffalo" is classified by the United States government as a type of cattle, and the government allows private herds to be managed as such.
This is a reflection of the characteristics that bison share with cattle. Though the American bison is not only a separate species, but also is usually regarded as being in a separate genus from domestic cattle Bos taurus , they clearly have a lot of genetic compatibility and American bison can interbreed with cattle, although only the female offspring are fertile in the first generation.
Many ranchers have deliberately crossbred their cattle with bison, and some natural hybridization could be expected in areas where cattle and bison occur in the same range.
Since cattle and bison eat similar food and tolerate similar conditions, they have often been in the same range together in the past, and opportunity for crossbreeding may sometimes have been common.
In recent decades, tests were developed to determine the source of mitochondrial DNA in cattle and bison, and most private "buffalo" herds were actually crossbred with cattle, and even most state and federal buffalo herds had some cattle DNA.
With the advent of nuclear microsatellite DNA testing, the number of herds known to contain cattle genes has increased.
Though about , bison exist on private ranches and in public herds, perhaps only 15, to 25, of these bison are pure and not actually bison-cattle hybrids.
One possible explanation for this might be the small amount of domestic cattle genes that are now in most bison populations, though this is not the only possible explanation for bison success.
In the study, cattle genes were also found in small amounts throughout most national, state and private herds. However, the extension of this herd into the Book Cliffs of central Utah involved mixing the founders with additional bison from another source, so it is not known if the Book Cliffs extension of the herd is also free of cattle hybridization.
A separate study by Wilson and Strobeck, published in Genome , was done to define the relationships between different herds of bison in the United States and Canada, and to determine whether the bison at Wood Buffalo National Park in Canada and the Yellowstone Park bison herd were possibly separate subspecies.
The Wood Buffalo Park bison were determined to actually be crossbreeds between plains and wood bison, but their predominant genetic makeup was that of the expected "wood buffalo".
Another finding was that the bison in the Antelope Island herd in Utah appeared to be more distantly related to other plains bison in general than any other plains bison group that was tested, though this might be due to genetic drift caused by the small size of only 12 individuals in the founder population.
A side finding of this was that the Antelope Island bison herd appears to be most closely related to the Wood Buffalo National Park bison herd, though the Antelope Island bison are actually plains bison.
In order to bolster the genetic diversity of the American bison the National Parks Service alongside the Department of the Interior announced on 7 May the Bison Conservation Initiative.
This initiative focuses on maintaining the genetic diversity of the metapopulation rather than individual herds. Small populations of bison are at considerably larger risk due to their decreased gene pool and are susceptible to catastrophic events more so than larger herds.
Specific smaller herds will require a more intense management plan. Translocated bison will also be screened for any health defects such as infection of brucellosis bacteria as to not put the larger herd at risk.
Among Native American tribes, especially the Plains Indians , the bison is considered a sacred animal and religious symbol.
Neyooxet Greymorning, "The creation stories of where buffalo came from put them in a very spiritual place among many tribes. The buffalo crossed many different areas and functions, and it was utilized in many ways.
It was used in ceremonies, as well as to make tipi covers that provided homes for people, utensils, shields, weapons and parts were used for sewing with the sinew.
The American bison is often used in North America in official seals, flags, and logos. In , the American bison became the national mammal of the United States.
In Canada, the bison is the official animal of the province of Manitoba and appears on the Manitoba flag.
It is also used in the official coat of arms of the Royal Canadian Mounted Police. Several American coins feature the bison, most famously on the reverse side of the " buffalo nickel " from to In , the United States Mint coined a nickel with a new depiction of the bison as part of its "Westward Journey" series.
The Kansas and North Dakota state quarters, part of the " 50 State Quarter " series, each feature bison. The Kansas state quarter has only the bison and does not feature any writing, while the North Dakota state quarter has two bison.
The Montana state quarter prominently features a bison skull over a landscape. The Yellowstone National Park quarter also features a bison standing next to a geyser.
