San Francisco Peaks

In the summer of 1935 it was realized that a large group of sites just to the east of Flagstaff, between the San Francisco Peaks and the Little Colorado River in northcentral Arizona, were in several respects unique. The presence in this northern area of ball court structures similar to those recognized in southern Arizona by Haury and others was the most outstanding single feature. Subsequently, more detailed research revealed additional southern, or Hohokam-like characters in these sites, and a program of several years of extensive excavation and research was undertaken.

Long Term Studies

Ten species of Testudines, from four different families: Chelidae, Kinosternidae, Podocnemididae, and Testudinidae, are reported from the Tiputini Biodiversity Station (Universidad San Francisco de Quito), northeastern Amazonian Ecuador; including the second report from Ecuador of Batrachemys heliostemma. These ten species are sympatric but not completely syntopic, thus I comment on their diversity and habitat preferences patterns. The general distribution of some turtles from Amazonian Ecuador is discussed, providing additional records and distribution maps for Chelus fimbriatus, Platemys platycephala, Batrachemys heliostemma, Batrachemys raniceps, Mesoclemmys gibba, Phrynops geoffroanus, Kinosternon scorpioides, and Geochelone denticulata. The presence of Peltocephalus dumerilianus in Amazonian Ecuador is confirmed; based on re-examination of specimens previously reported by Dr. Gustavo Orcés in 1949. The total Ecuadorian richness of Testudines species includes 31 living taxa, and I provide an annotated list of the turtles and tortoises of mainland and insular Ecuador. Much information is still needed in order to understand the ecological relationships of the Testudines from Ecuador and future research should focus on long-term studies designed to answer several questions about their biology and ecology. Several threats are currently jeopardizing the long-term conservation of turtle populations in Ecuador, and we must increase our knowledge on these amazing animals in order to protect and preserve them.

Stone Industry

About eight years ago there was discovered in the valley of the Little Colorado River between Hoi brook and Cameron in northern Arizona, evidence of an ancient alluvial terrace. Sand and waterworn pebbles largely derived from the Triassic Shinarump Conglomerate that once covered the area, form the deposit. The terrace which was formed by the gravels is now much dissected and remains only as the isolated flat tops of hills and ridges, the surfaces of which are covered with a desert pavement of waterworn pebbles. There are remnants also of later and lower alluvial deposits containing angular fragments of rock, of which a large proportion is made up of basaltic rocks from the San Francisco Peaks (Fig. 22).

Light microscopic immunohistochemistry based on the principle of capillary action staining is a widely used method to localize antigens. Capillary action immunostaining, however, has not been tested or applied to detect antigens at the ultrastructural level. The aim of this work was to establish a capillary action staining method for localization of intracellular antigens, using colloidal gold probes.Post-embedding capillary action immunocytochemistry was used to detect maternal IgG in the small intestine of newborn suckling piglets. Pieces of the jejunum of newborn piglets suckled for 12 h were fixed and embedded into LR White resin. Sections on nickel grids were secured on a capillary action glass slide (100 μm wide capillary gap, Bio-Tek Solutions, Santa Barbara CA, distributed by CMS, Houston, TX) by double sided adhesive tape. Immunolabeling was performed by applying reagents over the grids using capillary action and removing reagents by blotting on filter paper. Reagents for capillary action staining were from Biomeda (Foster City, CA). The following steps were performed: 1) wet the surface of the sections with automation buffer twice, 5 min each; 2) block non-specific binding sites with tissue conditioner, 10 min; 3) apply first antibody (affinity-purified rabbit anti-porcine IgG, Sigma Chem. Co., St. Louis, MO), diluted in probe diluent, 1 hour; 4) wash with automation buffer three times, 5 min each; 5) apply gold probe (goat anti-rabbit IgG conjugated to 10 nm colloidal gold, Zymed Laboratories, South San Francisco, CA) diluted in probe diluent, 30 min; 6) wash with automation buffer three times, 5 min each; 7) post-fix with 5% glutaraldehyde in PBS for 10 min; 8) wash with PBS twice, 5 min each; 9) contrast with 1% OSO4 in PBS for 15 min; 10) wash with PBS followed by distilled water for5 min each; 11) stain with 2% uranyl acetate for 10 min; 12) stain with lead citrate for 2 min; 13) wash with distilled water three times, 1 min each. The glass slides were separated, and the grids were air-dried, then removed from the adhesive tape. The following controls were used to ensure the specificity of labeling: i) omission of the first antibody; ii) normal rabbit IgG in lieu of first antibody; iii) rabbit anti-porcine IgG absorbed with porcine IgG.

Abstract Individuals with significant communication challenges need to communicate across many different venues. The author, from the perspective of an individual who uses AAC, discusses the strengths and weaknesses of both traditional AAC technologies and new mobile AAC technologies. He describes how access to AAC has allowed him to fulfill his dreams as a presenter and writer. He successfully manages a blog in San Francisco, writes grants, and has published his first book of poetry. Not one AAC device fits all of his communication needs; however, access to mobile technology tools has increased his flexibility across environments and given him another successful tool for communication.
