Defining Pure Bison
What is a pure bison
A pure bison refers to an individual of the species Bison bison that has no genetic influence from domestic cattle or other hybridization. Pure bison have a genetic makeup that is solely derived from the original, native bison population that once roamed the North American plains.
How to identify a pure bison
Identifying pure bison is a complex task that requires genetic testing. By analyzing DNA samples from bison herds, scientists can determine the level of domestic cattle influence in the population. Pure bison will have genetic markers that align with the original native bison population, while those with hybridization will exhibit genetic signatures of cattle.
Differences between pure bison and other bison
The key difference between pure bison and other bison lies in their genetic composition. Pure bison have a distinct genetic makeup that aligns with the native bison population, whereas other bison may exhibit traces of domestic cattle genes due to hybridization. It is crucial to preserve pure bison populations to ensure the preservation of the species in its most original form.
Historical Population of Pure Bison
Initial population of pure bison
In the past, vast herds of pure bison populated the North American plains, numbering in the millions. These herds played a significant role in the ecosystem and the lives of Indigenous peoples.
Changes in pure bison population through the years
Unfortunately, due to intense hunting, habitat loss, and diseases introduced by European settlers, the population of pure bison experienced a dramatic decline. By the late 19th century, the pure bison population was on the brink of extinction.
Factors causing decline in pure bison population
The decline in pure bison population can be attributed to several factors. The arrival of European settlers led to the loss of habitat through agricultural expansion, as well as uncontrolled hunting for their valuable hides and to diminish Indigenous populations. Additionally, diseases transmitted by domestic cattle, such as brucellosis and tuberculosis, further decimated pure bison herds.
