Great kivas, as communal architecture, are important in community integration. Exploring their distribution through the variables of time, space and form helps us understand change in community integration.

The patterns in the temporal and spatial distribution of the Silver Creek great kivas correspond to the patterning of these variables in the Upper Little Colorado region. The majority of Silver Creek great kivas appear in a period of westward population movement after A.D. 1000. The Silver Creek great kivas, do not, however, show the same range of formal variation. Since many of the changes in the Upper Little Colorado area are described as resolving problems of increasing population and aggregation, lower population densities in the Silver Creek area may explain the reduced formal variability of its great kivas.

Mean ring-width indices were used to compare growth between burned and unburned sites and between four different levels of fire severity. Mean growth increased in all sites in the post-burn periods relative to pre-burn periods. Favorable climatic conditions contributed to these growth increases. Post-fire mean growth for four out of seven burn sites, however, was significantly higher than that on unburned sites. In general, lower severity fire resulted in lower magnitude growth increases than those observed after moderate to higher severity fire. Very high severity fire that caused extensive foliage damage resulted in post-burn growth suppressions. Post-fire growth increases occurred whether post-burn years were wet or dry. Fire effects on site conditions may moderate climatic impacts on sequoia growth. Giant sequoia seedling establishment was favored by a combination of high severity fire and wet post-burn conditions.</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>32</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Cathey, Everett Henry</style></author></authors><tertiary-authors><author><style face="normal" font="default" size="100%">Butler, H.</style></author></tertiary-authors></contributors><titles><title><style face="normal" font="default" size="100%">Geophysics Education in North America</style></title><secondary-title><style face="normal" font="default" size="100%">Education Foundations and Administration</style></secondary-title></titles><dates><year><style  face="normal" font="default" size="100%">1976</style></year></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://ezproxy.library.arizona.edu/login?url=http://proquest.umi.com/pqdweb?did=760459481&amp;sid=8&amp;Fmt=1&amp;clientId=43922&amp;RQT=309&amp;VName=PQD</style></url></web-urls></urls><publisher><style face="normal" font="default" size="100%">University of Arizona</style></publisher><volume><style face="normal" font="default" size="100%">PhD</style></volume><language><style face="normal" font="default" size="100%">eng</style></language></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>6</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Burns, James M.</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">A Guide to Measuring Tree Ring Widths</style></title></titles><keywords><keyword><style  face="normal" font="default" size="100%">dendrochronology</style></keyword><keyword><style  face="normal" font="default" size="100%">guide</style></keyword><keyword><style  face="normal" font="default" size="100%">how to</style></keyword><keyword><style  face="normal" font="default" size="100%">measure</style></keyword><keyword><style  face="normal" font="default" size="100%">measurement</style></keyword><keyword><style  face="normal" font="default" size="100%">tree ring</style></keyword><keyword><style  face="normal" font="default" size="100%">width</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">1976</style></year></dates><publisher><style face="normal" font="default" size="100%">Laboratory of Tree Ring Research</style></publisher><pub-location><style face="normal" font="default" size="100%">Tucson</style></pub-location></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>19</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Fritts, H.</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Growth Rings of Trees: Their Correlation with Climate</style></title><secondary-title><style face="normal" font="default" size="100%">Science</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">climate</style></keyword><keyword><style  face="normal" font="default" size="100%">dendrochronology</style></keyword><keyword><style  face="normal" font="default" size="100%">growth</style></keyword><keyword><style  face="normal" font="default" size="100%">tree rings</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">1966</style></year></dates><volume><style face="normal" font="default" size="100%">154</style></volume><notes><style face="normal" font="default" size="100%">&lt;p&gt;Copies of this are available through the Tree Ring Laboratory.
