For the last 150 years bighorn sheep have decline to less than 2% of their population, by 1930 they were reduced to small remnant bands and were considered by some to be an endangered or rare species (fwiis,mt,gov). Bighorn sheep from Banff National Park (Alberta, Canada) was first introduced into National Bison Range around 1922 with credits to the Pittman-Robertson federal funding that provided the impetus for transplant of all game species ( Miller et al, 2012 ). The population has been monitored continuously since 1979, around 1985, 5 rams were introduced from neighboring Montana herds into this isolation population. A comprehensive genetic sampling began in 1988, and sheep were individually recognizable through individual phenotypes and ear tags (Miller et al, 2012), and a pedigree has been constructed based on behavioral and genetic data (Hogg et al, 2006). A second series of translocations occurred between 1990 and 1994, all from Montana herds except for one female from Wyoming herd. The present distribution and status of bighorn sheep in the National Bison Range is due to improved range conditions, reduced competition for forage from livestock and other wildlife, reductions in domestic sheep and goats, regulated hunting and transplanting. …show more content…
We then construct a dominance hierarchy, using abbreviated data set of observations of interacting rams from 2001 rutt provided by Dr.Jack Hogg. We then looked into the genetic and conservation consequences of dominance relationships and mating

Science Research Paper My project is about Invasive species of the Chihuahuan desert, which is located in Mexico and extends to southern Arizona through southern New Mexico and part of west Texas. I chose this project because I didn’t have a project and my teacher chose it for me, although it is an interesting topic. Before I start the project however; it is wise to do some research in order to gain a head start. Since my project is about, well invasive species, I should do some research on organisms…

Northern Bison Summary

In a summary paper (Disease in Northern Bison: what to do? in Buffalo, 1992), a panel member from the University of Saskatchewan (Gary Wobeser, a veterinary pathologist and wildlife disease expert, my undergraduate classmate at Guelph) pointed out that there were about 2,000 disease-free non-hybrid wood bison in the Mackenzie Sanctuary to the north which inevitably could become diseased from the park’s infected herd. He argued that the park’s bison population that had been declining for 20 years…
