recently in the scientific journal Acta Zoologica Mexicana, was published an interesting title that is BIOSTAT ANALYSIS OF STRESS RESPONDERS IN THE ANDEAN BEAR TOOTH ( Tremarctos ornatus) FOR THE BITE , this paper is authored by J. THE MORAL Sachetti Fernando (Argentina) ZENTENO Ramiro Cardenas (Bolivia) & Fatima I. LAMED CAMACARO (Venezuela).
We leave the meeting and a preview of work
S. Del Moral, JF, R. C. Zenteno and FI Lameda C. 2009. Biostatic analysis of stresses acting in the teeth of the Andean bear ( Tremarctos ornatus) during the bite. Acta Zoologica Mexicana (ns), 25 (3): 551-567. SUMMARY
. This study aimed to contribute to biological knowledge and the Andean bear biostatic ( Tremarctos ornatus) ursid fourth largest in the world and the largest carnivore living in the Neotropics. Maximum stresses were obtained applying the teeth during a bite, their reactions and behavior to shear and maximum bending moment along the span mandibular. To this end, we analyzed 3 complete skulls and teeth wild animals from Bolivia, using 9 skull measurements as descriptors. Maximum loads were considered bite in dogs (c) and second molars (M2). Also determined the intensity of them, by calculating the higher voltages reached in these sections, depending on the tensile strength (kg/mm2 sR = 0.50). The final proposed system responds to two sections of indeterminate structure and its resolution was performed using the method of successive approximations of Cross. It was found that maximum bite force in the male is 246.90 kg being approximately 1.34 times greater in the molars. The female gets to have a bite of 184.96 kg and a milling intensity of 285, 75 kg. The current rise in more than 80 kg in the molars to the canines, is directly proportional to the great development of the temporalis muscle-masseteric as the structural design of bone in the pit of the same name and width of the face on a molar. These characters biostatic denote the specialization of the skull and teeth of the kind designed to withstand heavy loads, the product of crushing and grinding tough fibrous plants in general, and a unique training male predation. Making it possible for the Andean bear to have a varied diet and opportunistic in its ecological niche, adaptable to food resources that the environment offered.
Keywords: Andean Bear, Tremarctos ornatus, biostatic, hyperstaticity, Cross method.
