Thin Section Petrography Of Pottery From Ambergris Caye, Belize, Elizabeth Haussner
Anthropology
Petrography is a valuable tool in which ceramics are studied at a microscopic level, revealing structures, features, and compositional information undiscernible at the macroscopic level. This study uses petrography to investigate Coconut Walk Unslipped (CWU), a pottery type prominent at Late Terminal Classic Mayan archaeological sites on Ambergris Caye, Belize. All CWU sherds in this study are tempered primarily with quartz sand grains although the grains vary in roundness. They also contain small amounts of microcrystalline sparry calcite features. These findings are similar to those of the 1999 study by Iceland and Goldberg on ceramic sherds of a similar age …

Color Vision Variation As Evidenced By Hybrid L/M Opsin Genes In Wild Populations Of Trichromatic Alouatta New World Monkeys, Barbara Welker, Yuka Matsushita, Hiroki Oota, Mary S. Pavelka, Shoji Kawamura
Anthropology
Platyrrhine (New World) monkeys possess highly polymorphic color vision owing to allelic variation of the single-locus L/M opsin gene on the X chromosome. Most species consist of female trichromats and female and male dichromats. Howlers (genus Alouatta) are an exception; they are considered to be routinely trichromatic with L and M opsin genes juxtaposed on the X chromosome, as seen in catarrhine primates (Old World monkeys, apes, and humans). Yet it is not known whether trichromacy is invariable in howlers. We examined L/M opsin variation in wild howler populations in Costa Rica and Nicaragua (Alouatta palliata) and …
