![]() We also investigated the structural role of the pteric area within the cranial functional matrix, in order to test possible relationships between its variation and the degree of airorhynchy. This study is aimed at investigating the variation and covariation patterns in howler monkeys, considering both inter and intrageneric morphological differences. However the evolutionary changes associated with the cranial organization in Alouatta are still currently unknown. In terms of functional craniology, airorhynchy may be related to structural changes associated with the morphology of the supraorbital anatomy, with the spatial relationships between face and cranial base, or with morphogenetic variations of the pteric area. This condition may be evolutionarily influenced by a largely folivory diet (with selective pressures on mandibular and splachnocranial dimensions), social structure (related to the development of vocal sacs), or by the interaction between these or other more subtle factors. Howler monkeys (genus Alouatta) display a peculiar cranial architecture, characterized by a high degree of airorhynchy. Advantages and limits of the method are discussed accordingly. Although this study rely only on raw geometry without considering further anatomical or histological elements, some differences between modern humans, Neandertals, and Australopithecines merits attention. After CT-based endocasts reconstruction and voxel-based 3D model rendering, we find numerically the stationary heat distribution on the regular lattice defined by the voxels. Combining digital imaging and numerical integration techniques, we used the heat equation to quantify heat dynamics on the surface of fossil endocasts, dividing the space in a three dimensional cubic lattice. Here, we present a model to analyze heat dispersion on fossil endocasts, as function of brain geometry and basic physical properties associated with heat conduction. Cortical and meningeal vessels have been hypothesized to have a functional role in this sense, as suggested by anatomical differences among fossil hominids. At the same time there is little information on the thermoregulatory biology of the brain mass in our own species. Currently, there is no agreement on the existence of specific cooling mechanisms in Homo sapiens to balance the heat production related to such high metabolic rates. Main St., Newton, KS 67114.Brain evolution in the human genus is associated with a definite increase in metabolic expenditure. Memorial donations may be made in her memory to Caring Hands Humane Society in care of Petersen Funeral Home 215 N. ![]() Private family services have taken place. Neysa was a member of the Congregational Church until she joined the Unitarian Universalist Church of the Larger Fellowship. Survivors include her son Terrill Lynn Eberhard of Peabody sister by choice Betty Breukelman Schelske and her husband Claire of Gainsville, Florida, as well as a host of nieces and nephews and cousins that make up her extended family. ![]() Charles and Neysa had one son Terrill Lynn Eberhard of Peabody, who survives his parents. They were married Apil 22, 1946, at the Breukelman home in Emporia by the minister who also married Anne and Betty, as well as baptized all their children. Her final 16 years of work were spent as director of the Newton Public Library.ĭuring her first teaching assignment in Peabody, she met Charles Louis Eberhard. Her career of 35 years included teaching and librarianship in Peabody, Marion, Newton and at Oklahoma State University. She earned a doctorate in education from Oklahoma State University. Neysa received from Emporia State University her high school diploma, bachelor of science and master of library science degrees. After the death of her mother, she moved to Emporia to become part of her mother?s sister?s family: Ruth and John Breukelman and their daughters Anne and Betty. Moving to Huron, South Dakota, at the age of 6, she attended the Huron schools until 1937. Neysa was the only child of her parents, who preceded her in death. 28, 1921, at the homestead of her parents, Walter and Rachel Perrin Koehler in Elbon, South Dakota. Neysa Cecelia Koehler Eberhard, 93, died on Wednesday, Nov.
