"Details: This polar bear skull model is perfect for many purposes. To name a few: scientific study, personal collection, sketch making, exhibition, home decoration, or best of all, as a very distinguished gift! We bought this model at a great price when we were visiting the Venerable 70-year-old Budhalo Karmachenco in the town of Bellager, Chukotskiy Autonomy of Russia. In the living room we noticed in awe what was laid before the fireplace was an intact hide of polar bear, and hung above the fireplace a giant polar bear skull! The Venerable host sensed our astonishment and began the storytelling about the hide and skull. Back in 1970, the herds of the village was assaulted again and again by a stray polar bear, who at last went on to kill a child in broad daylight. This last straw prompted the villagers into action, who assembled a hunting squad to go after the cold-blooded murderer. “He shouldn’t have killed the child, not the lambs or horses either of course, which were all national treasure! If Stalin ever found out, this bear friend would have been sent to the Mongolian desert at the heat of high summer to repent and self-criticize for his wrong-doings!” said the excited elderly host as he took another full puff. Then the best hunter in the village, with the sharpest shotgun and fiercest Russian wolf-dogs, he naturally became the leader of the squad. It was a bloody hard battle; they finished off the bear in the end, but not without their share of grave expenses. 7 out of 12 wolf-dogs died fighting, including 4 of his own; the survivors all sustained severe wounds as well. How would such a blood-thirsty monster look like? Indeed we missed that epic battle, but what you can do, if to own this polar bear skull and feel the raw power" www.propsport.com/11-polar-bear-skull-model-p-101.html |

"...The shape of the nose seems to be important, too: "It is possible to recognise scavenger bears even by their nose. Those who graze have short noses and the scavengers have long noses, and they are yellow." It is unclear where this knowledge comes from, since this hunter told me: "According to the literature we refer to, the carnivorous one, by his head, he has got a shorter mouth and longer teeth, as herbivorous, this is a similar sort of bear but he has got a longer mouth, and we distinguish them like that." It is noteworthy to remember that there can be strong intra-specific variations in the skull's shape among bears (Stirling & Derocher 1990; Ohdachi et al. 1992), ..." shaggygod.proboards.com/index.cgi?board=generalinfo&action=display&thread=73&page=1 |

"...Merriam raised an even more amazing conundrum. He declared in his monograph that five different species of brown bear came from Admiralty Island in southeastern Alaska. This island, eight kilometres from the mainland, is only 145 km long and 55 km wide, a wilderness with a few coastal settlements focused on lumbering and fishing and with many bears in the interior. To most people familiar with the area, it seemed impossible that these five types, difficult to tell apart as individuals let alone as species, stuck to their own kind among the trees, never mating with a bear from one of the other four groups despite the limited area they all inhabited. Bears, like other mammals, are classified largely in the laboratory through the examination of skulls and skins sent to museums for this purpose. From his museum research, Merriam knew that the shape of bear skulls varied with the sex and the age of the animals. What must have intrigued him was that bear skulls varied for other unknown reasons too. He could have said to himself, "Bear skulls have all sorts of different shapes; could that be because they are omnivores and have a variety of diets? Maybe one bear eats mostly berries and another likes to gnaw bones, so that their facial muscles develop differently and their skulls look different too?" Instead, Merriam decided that differences in skull characteristics meant different species, or at least different subspecies subspecies, also called race, a genetically distinct geographical subunit of a species. See also classification..." "...Merriam was aware that many zoologists would be surprised by his bear classification and would believe, like Roosevelt, that he had conjured up too many different species. He writes defensively in his monograph, "The number of species here given will appear to many as preposterous. To all such I extend a cordial invitation to visit the National Museum and see for themselves what the bear skulls show..." www.thefreelibrary.com/Prestige,+power,+and+the+naming+of+brown+bears.-a030110966 |

SKULL SHAPE VARIATION IN THE APENNINE BROWN BEAR: IMPLICATIONS FOR
CONSERVATION

Molecular studies highlighted a strong genetic affinity between the remnant and isolated population of
the Apennine brown bear (Ursus arctos masricanus) and other west European bear populations1 , 2,
even though a recent morphometric study revealed extensive phenotypic diversity of the Apennine
population suggesting U. arctos marsicanus is a good candidate for subspecies status.
Morphological investigations, especially by revealing unique shape features despite genetic
similarities, may complement taxonomic analyses or aid in the identification of Evolutionary Significant
Units for conservation. By building upon previous traditional morphological analyses, we hereby adopt
geometric morphometries to investigate skull shape differences between the Apennine and other west
European bear populations.
We hereby apply geometric morphometries to a sample of 65 adult brown bear skulls from four
populations (Central Italian Apennines, Alps, Croatia and Bulgaria) by using a set of 20 landmarks
along the dorsal line of the skull. Shape variation among populations was investigated by principal
component and canonical vanate analyses. Despite the close genetic relationship with other west-
European bear populations, U. arctos marsicanus features a significant shape divergence,
corroborated previous traditional morphometries findings, and suggest that genetic drift could have
greatly accelerated morphological evolution and contributed to the origin of morphological
novelties.These preliminary results enphasize the evolutionary distinctiveness of U. arctos marsicanus
and underline the importance of morphological analyses as a complementary tool to molecular
analyses for a more thorough characterization of population divergence, and hence effective
conservation planning.
