how many musk ox are there in the world
Muskox Historically, this species declined because of overhunting, but population recovery has taken place following enforcement of hunting regulations.[1] Management in the late 1900s was mostly conservative hunting quotas to foster recovery and recolonization from the historic declines.[1] The current world population of muskoxen is estimated at between 80,000[48] and 125,000,[29] with an estimated 47,000 living on Banks Island.[49]
Isotopes of oxygen Naturally occurring oxygen is composed of three stable isotopes, 16O, 17O, and 18O, with 16O being the most abundant (99.762% natural abundance). Depending on the terrestrial source, the standard atomic weight varies within the range of [15.99903, 15.99977] (the conventional value is 15.999). Known oxygen isotopes range in mass number from 12 to 24.
