Article #25 The Science and Evolution of Human Skin Color. HTn0}Wpo6E6]{V{D/e7~NX$ER< Mother bears are also producing smaller cub litters, which the team projected will continue to decline for the next three polar bear generations. But the rate at which species interbreed is accelerating because of climate change, researchers say. A polar bears life seems simple enough: eat seals, mate, and raise cubs. Considering that human activity has indirectly brought together species through planetary warming and increased fossil fuel emissions, the question on the minds of many biologists like Arnold is whether humans should play a role in preventing hybridization like this. Story by Kasha Patel. Article highlights include: Franklin's achievements as a child; her research into the structure of coal which earned her a PhD; her apprenticeship for learning about X-ray diffraction; her appointment to work at King's College to help discover the structure of DNA; the tensions and hostilities with her research partner Maurice Wilkins; her success at obtaining excellent X-ray diffraction images of two forms of DNA; Wilkin's release of these images to a rival team (James Watson and Francis Crick) of researchers without telling Franklin; Franklin's research into the structure of plant viruses; Franklin's early death due to ovarian cancer at the age of 37 and the controversy over her not being acknowledged by the Nobel Prize committee. The Prius isnt the only environmentally conscious hybrid out there. Specialists like the polar bear are at greater risk of extinction, especially if their habitat is literally melting away.. With global warming and sea-ice declines, it becomes harder for polar bears to hunt their preferred preyseals. An unusual bear shot by a hunter days ago in Nunavut, a territory in northern Canada, is thought by experts to be a "grolar" or "pizzly" bear. Additional licenses can be purchased at a discount for others to use in your department. The combination of warmer temperatures and vegetation growth means there is more overlap between the species and Id expect that overlap to increase, Chris Servheen, a grizzly bear expert at the University of Montana, told the Guardian. docs, slides, etc.). maximillia scheider cause of death NASA Earth Observatory images by Joshua Stevens, using data courtesy of Kristin Laidre and Harry Stern at the University of Washington, and sea ice data from the National Snow & Ice Data Center (NSIDC).

While polar bears have longer skulls in order to grab seals out of the water, their molars are smaller than is typical for their body size because all they eat is blubber all day. So-called "pizzly" bears were first spotted in the wild in 2006.

Beyond speculation, two real cases of pizzly bear offspring in the wild (as confirmed by genetic testing) is discussed along with the possibility of other Arctic hybrids. My other classes were interested when they read my agenda. Genetic exchange due to organisms coming together from climate change is the rule rather than the exception.. Snow and Ice. Even if greenhouse gases were curbed immediately, sea ice would likely continue to decline for several decades because large-scale changes take a long time to propagate through Earths climate system. (NEXSTAR) A new breed of hybrid polar and grizzly bear has been seen stalking the arctic, and experts say the new species arose due to the effects of climate change.
