The large protected areas in the NCDE allowed movement of bears bringing new genes into areas that had historically been dominated by few bear families, increasing the flexibility of the population to adapt to future changes. That a nine-foot grizzly is the largest bear killed by a hunter in Alaska is likely to come as a surprise to Alaskans, some number of whom — hunters or not — might have seen 10-foot grizzly bears. Rapid increases in grizzly bear genetic diversity in the Crown of the Continent, Figure 1. UPHEAVAL – my new ice tsunami novel – is now available! USGS researchers then built a massive family tree with the 1115 bears and were able to show that each southern region was almost entirely dominated by single extended grizzly bear families in 2004 (figure 3). The grizzly family tree will allow us to answer questions about dispersal, effective population size, similarity of diet and habitat between offspring and mothers, inbreeding, and the relationship between habitat and fitness (the number of offspring a bear has). In striking out on their own to areas far from where they were born (figure 4), these bears improved the genetic health of the population. These bears also occur across the north slope of Alaska and are the bears that occasionally hybridize with polar bears this time of year, as explained here. New individuals can increase the genetic diversity in an area by bringing new or rare genes. Adapted from Mikle and others, 2016. The world-record Alaska brown bear, taken in Kodiak in 1952, is much larger. Verso of cover. These two examples show how the genetic diversity in an area can be due to few individuals having very high reproductive success. Sorry, your blog cannot share posts by email. Of the six established grizzly bear recovery zones, the NCDE is the third largest in area, potentially harboring the greatest number of grizzly bears, and is the only zone contiguous to a strong Canadian population. The ancestors of the grizzly bears in Eurasia and North America were about 50,000 years ago. Movement into low genetic diversity regions. Genetic diversity is usually a very slowly changing measure of the health of the population and the movement we observed was responsible for the rapid increases in diversity.

The maternal ancestors of modern polar bears were from Ireland, ... Hybridisation has been recorded recently in the wild where grizzly bears have encroached on polar bear territories. This USGS study highlights the importance in maintaining movement corridors for wildlife to ensure that the genetic health of populations is maintained or improved. Watch polar bear habitat reform in the Canadian Arctic: “last 10 days” Canadian Ice Service animation (works anytime). Generally speaking, breeding between close relatives, a small population size, and difficulty moving throughout an ecosystem can all lead to lower genetic diversity. Now, scientists have discovered one of the earliest ancestors of all modern carnivores in Belgium. Apparently, all media outlets (except Fox News) so confused the distinction between the two common names used for the ancestor of polar bears, Ursus arctos, that they got the point of a recent news story totally wrong.

Many young bears moved into the southeast region (SE) from long distances away (blue plusses) between 2004 and 2012, showing the high degree of connectivity in the NCDE. Black polygons encompass buffered regions of interest due to low genetic diversity in 2004, clipped by the sampled study area (double lines). First, researchers calculated genetic diversity from samples collected in 2004 for each bear and its neighbors and found that three regions that had lower genetic diversity than the rest of the ecosystem (EC, SE, SW in figure 2).
