Question

climate change and pizzi
(6) four years later, in 2010, david kuptana, an inuvialuit hunter killed what he thought was a polar bear on victoria island, near nunavut. this bear also looked a little different from the standard polar bear so he had the bear’s dna tested. it turns out that the bear was the offspring of a pizzly mother and a grizzly bear father. this was the first solid evidence that pizzlies created in the wild could be fertile.
(7) though the arctic is not currently overrun with pizzlies, and in fact it would be quite extraordinary to find a living specimen, some scientists speculate that pizzlies might be more common in the future as encroaching more and more arctic regions of the polar bear
(8) not only might climate change pizzlies, it might also promote other arctic hybrids. sightings and beluga whale hybrids have been hooded seal and harp seal hybrids bowhead whale and north pacific hybrids are already suspected to produced as the warming oceans increased overlap in their territori hybrids and more might be a part of
article questions

1. how is climate change threatening the availability of sea ice?
2. explain two reasons why sea ice so important to a polar bear.
3. what is a pizzly? what is another name for a pizzly?
4. what parts of a pizzly resemble that of a grizzly bear?
5. what proof is there that pizzlies can be made in the wild?
6. what proof is there that pizzlies can be fertile?
7. how might the changing climate be the cause of more wild pizzlies in the future

Explanation:

1. Climate change causes global warming, which leads to the melting of sea - ice. Rising temperatures from climate change increase the rate of ice - melt in polar regions.
2. Polar bears use sea ice for hunting seals (their main prey) as seals come up for air through holes in the ice. Also, sea ice serves as a platform for polar bears to travel and rest.
3. A pizzly is a hybrid of a polar bear and a grizzly bear. Another name for it is a grolar bear.
4. Pizzlies may have grizzly - like features such as a hump on the shoulders and a more concave face compared to pure polar bears.
5. In 2010, David Kuptana killed a bear on Victoria Island which was tested and found to be the offspring of a pizzly mother and a grizzly father, providing the first solid evidence that pizzlies can be made in the wild.
6. The bear killed by David Kuptana in 2010 was the offspring of a pizzly mother, indicating that pizzlies can be fertile as the mother was able to reproduce.
7. Climate change is causing the ranges of polar bears and grizzly bears to overlap more as polar bears are forced to move south due to melting sea - ice and grizzly bears are moving north due to warming temperatures, increasing the chances of inter - breeding and more wild pizzlies.

Answer:

1. Rising temperatures from climate change cause sea - ice to melt.
2. Used for hunting seals and as a travel and resting platform.
3. A polar bear - grizzly bear hybrid; grolar bear.
4. Hump on shoulders and more concave face.
5. A bear in 2010 was found to be the offspring of a pizzly mother and grizzly father.
6. A bear in 2010 had a pizzly mother, showing pizzlies can reproduce.
7. Ranges of polar and grizzly bears are overlapping more due to climate change.
