Tree-ring records were used to reconstruct the spatial and temporal patterns of western spruce budworm (Choristoneura occidentalis Freeman) outbreaks in the Rio Grande National Forest (RGNF) of southern Colorado. Reconstructions at 11 host stands showed a synchronous pattern of outbreaks with a peak in the number of trees recording outbreaks over the entire RGNF on average every 24 years. These synchronous periods of outbreaks coincided with periods of increased moisture as indicated by an independently reconstructed summer Palmer Drought Severity Index, while relatively few trees recorded outbreaks during dry periods. The reconstruction on the RGNF does not support the hypothesis that human land use has significantly altered outbreak patterns. Tree response to outbreaks in the RGNF was different from prior studies as reductions in the growth were typically detectable only when growth was compared to that of nonhost tree species.

The PNA circulation pattern corresponds with cooler temperatures on the Colorado Plateau, whereas the reverse-PNA circulation pattern corresponds with warmer temperatures on the Colorado Plateau associated with a high pressure ridge over the Rocky Mountains. Temperature was reconstructed using three Pinus aristata (bristlecone pine) chronologies and one Pinus flexilis (limber pine) chronology from subalpine sites located on either side of the Continental Divide in Colorado and Arizona. The standardized ring-indices of the four chronologies (scAD 548-1994) were correlated with historic temperature data from twelve ground stations and upper air temperature data from four radiosonde stations in Arizona, Colorado, New Mexico and Utah. Temperature reconstructions across a transect spanning the Continental Divide on the Colorado Plateau provide valuable insight to temporal changes in large scale circulation patterns. Reconstructions of annual temperature indicate there were several periods when temperatures were below the modern mean east of the Continental Divide when they were above the modern mean west of the Continental Divide. Variability in the direction of temperature change on either side of the Continental Divide may reflect a westward displacement of the high pressure ridge at different times in history. Reconstructions of annual temperature also indicate 850 mb temperature east of the Divide is slightly higher when the PNA circulation pattern occurs as a teleconnection to El Nino Southern Oscillation (ENSO) events. In contrast, annual 700 mb temperature west of the Divide is slightly lower. Temperature reconstructions also indicate higher mean annual temperatures occurred between scAD 550 to 600, scAD 900-980, and scAD 1040-1080, and scAD 1130-150 than between 1950 and the present. These reconstructions suggest low frequency cycles of above average temperatures have occurred throughout history. These results indicate more research is required to determine whether recent warming trends identified by other researchers reflect anthropogenic warming or natural cycles. }, keywords = {Bristlecone, Continental divide, Limber pine, Pinus, Temperature reconstructions}, url = {http://ezproxy.library.arizona.edu/login?url=http://proquest.umi.com/pqdweb?did=732946061\&sid=18\&Fmt=2\&clientId=43922\&RQT=309\&VName=PQD}, author = {Diane Douglas} } @mastersthesis {590, title = {Tsegi Canyon Cliff Ruin Beam Coring Project: A Dendrochronological Analysis of Six Sites in the Tsegi Canyon Complex, Northeastern Arizona}, volume = {MA}, year = {1997}, school = {University of Arizona}, keywords = {Archaeology}, author = {Wright, William Edward} } @mastersthesis {504, title = {Tree-Ring Reconstructions of Climate and Fire History at El Malpais National Monument, New Mexico}, volume = {PhD}, year = {1995}, school = {University of Arizona}, abstract = {The purpose of this research was to: (1) reconstruct climate for the malpais region from long-lived trees and remnant wood; (2) reconstruct the fire history of forests in the malpais; and (3) investigate short-term and long-term relationships between wildfire and climate. To reconstruct climate, I calibrated a 2,129 year long tree-ring chronology (136 BC-AD 1992) with annual rainfall (previous July to current July). Since AD 100, seven major long-term trends in rainfall occurred. Above normal rainfall occurred during AD 81-257, 521-660, 1024-1398 and 1791-1992, while below normal rainfall occurred during AD 258-520, 661-1023 and 1399-1790. The prolonged drought from AD 258-520 was unsurpassed in its intensity, while rainfall during the most recent 200 years has exceeded any since AD 660. The reconstruction of long-term climate trends confirmed the general sequence of environmental change over the last 2,000 years for the southern Colorado Plateau. To reconstruct past fire occurrences, 217 fire-scarred trees were collected from nine sites representing the major habitat types of the malpais and dendrochronologically dated. Fire frequency was highest at sites on cinder cones and on the highly-weathered basalt flows (ca. once every five years), and lowest on the isolated kipukas and on the Hoya de Cibola Lava Flow (once every 10-12 years). Fire frequency decreased along a north to south gradient, reflecting changing vegetation properties. Combined information revealed fire occurred once every two years, while more widespread fires occurred once every 2.5 years. Fires were largely asynchronous between sites, suggesting the malpais landscape effectively hinders fire spread. Past fire history at El Malpais was characterized by four temporally distinct periods: (1) FH-1 (prior to 1782): high fire frequency, patchy fires, throughout the growing season; (2) FH-2 (1795-1880): longer fire intervals, widespread fires, mostly early season fires; (3) FH-3 (1893-1939): even longer intervals, decreased widespread fires; (4) FH4 (1940-1992): longest fire-free periods during the last 600 years. The increase in rainfall and the simultaneous change in fire regimes ca. 1790 was likely related to an increase in summer monsoonal rainfall due to changes in hemispheric circulation patterns. The decrease in fire spread ca. 1880 was most likely due to intense sheep grazing, while the change ca. 1940 reflects greater efficiency in fire suppression techniques. The presettlement fire regime emphasizes that the current absence of fire in the monument exceeds the historical range of variability established for the presettlement period. Unless effects of past human-related disturbances are mitigated, fire regimes of El Malpais will continue to favor high-intensity, catastrophic fires.}, url = {http://ezproxy.library.arizona.edu/login?url=http://proquest.umi.com/pqdweb?did=742088811\&sid=3\&Fmt=2\&clientId=43922\&RQT=309\&VName=PQD}, author = {Grissino-Mayer, Henri Dee} } @mastersthesis {568, title = {The Tree-Ring Record of False Spring in the Southcentral USA}, volume = {PhD}, year = {1990}, school = {Arizona State University}, abstract = {Frost injuries are common in the annual rings of deciduous oaks of the southcentral United States, and can be identified microscopically by unique anatomical criteria. A chronology of 70 frost ring years between 1650 and 1980 has been developed from 42 collection sites in the Southern Plains. False spring conditions cause frost rings in oaks, and include both an abnormally warm winter and the subsequent severe freeze in spring (temperatures must fall to <= 23 {\textdegree}F or -5 {\textdegree}C). Major circulation changes over North America often occur from the warm to cold phase of false spring. An upper level trough over Southern California and surface high over the Southeast favor warm air advection into the Southern Plains during the warm phase. This pattern is usually replaced by a deep upper level trough over the central USA and a strong surface ridge often extending from Canada to Mexico during the cold phase. The resulting cold air advection often causes heavy damage to crops and native vegetation which are prematurely advanced by the preceding mild weather. These false spring episodes include both climatological and meteorological signals, and the consistent registration of specific weather conditions by frost rings establishes the feasibility of {\textquotedblleft}dendrometeorology{\textquotedblright}. Frost rings in oaks often form during La Nina events, and may reflect a tropical influence on both above and below average winter temperatures in the Southern Plains and Canada, respectively. Warm winters in the Southern Plains favor premature growth, and cold Canadian winters may help explain the severity of the late cold wave which terminates false spring. False spring occurrence has been nonrandom over the past 331 years, and the many one- and three-year intervals between events may partially reflect La Nina forcing. In contrast, an El Nino influence on the formation of bristlecone pine frost rings and light rings in Canadian black spruce has been detected in previously published chronologies. The co-occurrence of oak frost in spring followed by light rings in summer often reflects an enhanced La Nina-El Nino cycle. An amplified El Nino-Southern Oscillation (ENSO) may be suggested by the four such co-occurrences from 1814 to 1819, which could help explain many ambiguities in the worldwide temperature response to the cataclysmic eruption of Tambora in 1815.}, url = {http://ezproxy.library.arizona.edu/login?url=http://proquest.umi.com/pqdweb?did=744592481\&sid=13\&Fmt=2\&clientId=43922\&RQT=309\&VName=PQD}, author = {Stahle, David W.} } @mastersthesis {505, title = {Tree Rings of Shortleaf Pine (Pinus Echinata Mill.)

INTRODUCTION

Two final collection trips were made to the Pueblo de Acoma the week of May 15, 1988 and the week of July 19, 1988. The crew again consisted of the author and Jeffrey S. Dean, both from the Laboratory of Tree-Ring Research.

Once again the purpose of the trips was to complete work in Area H that had been bypassed on previous visits. This work was in fact completed during the second trip, but the May trip was diverted to work in Area A and Area B because Area H was not yet cleared of household goods. We were fortunate during the May visit to locate a number of structures, uninvolved with the Restoration Project, whose owners gave us permission to core.

A considerable amount of time on both trips was spent comparing the plans of the Restoration Project with the plans drawn by the Historic American Buildings Survey in 1934 (Nabokov 1986; see reference in the initial report). As a result, a concordance of the numbering systems was developed (Table 2) to serve as a measure of architectural chance between 1934 and 1988. One unit could not be identified with any certainty and the units in Area F are less than certain. All others are, however, clearly cross referenced.

INTRODUCTION

A second collection trip was made to the Pueblo de Acoma the week of October 12, 1987. The crew consisted of the author and Jeffrey S. Dean, both from the Laboratory of Tree-Ring Research.

The purpose of the trip was to complete those units in Area H that had been bypassed in April 1987. However, since the expected HUD funding had not yet been received, the Restoration Project was not active and the Area H units were still unavailable. As a consequence, only a single unit was cored in Area H with the remainder of the work done in Area F and Area C.

In addition, we had the opportunity to survey Cebolleta Mesa and adjacent areas for living trees, particularly pinyon (Pinus edulis), that might be old enough to overlap with the beams cut in the mid 1600s. This of course would mean trees of an age class of 350 \– 400 years; not impossible for pinyon, but relatively rare. We located two sites, one near Indian Lake on Cebolleta Mesa and one at Mesa Negra Spring at the western edge of the reservation. Both sites should be tested for tree age to determine if full coring is warranted.

For both these activities, coring at Sky City and reconnaissance, we were accompanied by Marvin C. Garcia and Dwight Lucario. Our accomplishments are due in large part to their helpfulness and good humor.

INTRODUCTION

In the spring of 1986, the Laboratory of Tree-Ring Research was contacted by the Laboratory of Anthropology, Museum of New Mexico regarding participation in archaeological clearance of the Pueblo de Acoma (Sky City) Rehabilitation Project. This project, funded by a Department of Housing and Urban Development (HUD) Community Development Block Grant, had been ongoing since 1982 but only recently had considered compliance with the National Historic Preservation Act of 1966 (Section 106).

A meeting and field inspection was held at Acoma in September 1987 with representatives of the Sky City Rehabilitation Project (Vallo), the Museum of New Mexico (Ware, Adams, Ladd), and the Laboratory of Tree-Ring Research (Robinson, Dean). This meeting resulted in, among other things, a commitment from the Laboratory of Tree-Ring Research to participate in the archaeological clearance and to seek its own funds to do so. As a consequence, a proposal and a budget covering the field work was submitted to a local Tucson foundation and funding was obtained. In the meantime, the Museum of New Mexico continued to work with the Pueblo de Acoma and HUD in developing an application for a new Block Grant.

A second meeting was held at Acoma in January 1987 to discuss implementation of the cooperative agreement. In addition to the previous representatives, the Rehabilitation Project consulting architect (McHenry) and the Bureau of Indian Affairs archaeologist (Harrill) were present. Specific clearance of Area H was discussed and it was agreed that the Laboratory of Tree-Ring Research project should be implemented in advance of construction and that some sampling in Area C would be possible in late April 1987.

A final meeting was held in the council chambers of the Pueblo de Acoma on April 21, 1987 with homeowners in Area H whose houses were targeted for rehabilitation in 1987. In addition, the meeting was attended by First Lt. Governor Ray Histia, Mr. Greg Histia of the Acoma Development Authority, Mr. Dennis Vallo and Mr. Marvin Garcia of the Rehabilitation Project, and Dr. John Ware and Mr. Tom Livesly of the Museum of New Mexico as well as the Laboratory of Tree-Ring Research crew. Discussions were held regarding scheduling and coordination of the Laboratory\’s work and the concerns of the homeowners. Many homeowners asked questions about how vigas were sampled, how much time it would take, and whether any disturbance would occur. At the conclusion, all homeowners expressed satisfaction and real interest in the project.

The problem of standardizing closed-canopy forest ringwidth series is investigated. A biological model for the tree-ring standardization problem indicated that one class of non-climatic variance frequently responsible for standardization problems could be objectively minimized in theory. This is the variance caused by endogenous stand disturbances which create fluctuations in ringwidth series that are non-synchronous or out-of-phase when viewed across trees in a stand. A time series method based on the autoregressive process is developed which minimizes the timewise influence of endogenous disturbances in detrended ringwidth series. Signal-to-noise ratio (SNR) properties of this method are derived which indicate that autoregressive modelling and prewhitening of detrended ringwidth indices will result in a higher SNR when endogenous disturbances are present in the series. This enables the verification of the SNR theory and the error variance reduction property of the standardization method.

The objective is to document which of the available regression methods are best suited to deciphering the complex link between tree growth variation and climate. Tree-ring response function analysis is used to determine which instrumental climatic variables are best associated with tree-ring width variability. Ideally such a determination would be accomplished, or verified, through detailed physiological monitoring of trees in their natural environment. A statistical approach is required because such biological studies on mature trees are currently too time consuming to perform. The use of lagged climatic data to duplicate a biological, rather than a calendar, year has resulted in an increase in the degree of intercorrelation (multicollinearity) of the independent climate variables. The presence of multicollinearity can greatly affect the sign and magnitude of estimated regression coefficients. Using series of known response, the effectiveness of five different regression methods were objectively assessed in this study. The results from each of the 2000 regressions were compared to the known regression weights and a measure of relative efficiency computed. The results indicate that ridge regression analysis is, on average, four times more efficient (average relative efficiency of 4.57) than unbiased multiple linear regression at producing good coefficient estimates.

Rich.) is a desirable species for tree ring studies due to its longevity, resistance to decay, and the statistical characteristics of the ring record (Bowers, 1973). This investigation endeavors to determine: (1) the type and number of samples needed for such studies; (2) the values of x-ray densitometry analysis with the species; (3) the usefulness of the data for delineating differences in swamp sites which differ in length of flooding and if these differences could affect wood quality; and (4) the appropriateness of the data from disturbed swamp sites in south Louisiana to dendroclimatic studies. Differences exist in eight sample types. Furrow samples have a large number of missing and/or merging growth rings, are difficult to measure, and their statistical characteristics are no better than those of lobe samples. Compass direction is not significant but south samples contain twice as many resinous bands. Over 50\% of the chronology variance is accounted for by differences among core chronologies. Thus, it is beneficial to take two or more samples per tree. A sample size of 120, four cores from thirty trees, is required to reduce the standard error of the sample mean to .05 or less. X-ray densitometry did not alleviate problems with crossdating and false rings which are common with baldcypress. Although statistical characteristics of the density parameters do not indicate their use in dendroclimatic studies, the density data are significantly correlated with both mean monthly precipitation and temperature. A shift in hydrology from permanently to seasonally flooded enhanced wood production in good years; and, maximum latewood became more homogeneous among trees. Wide rings are characterized by increases in density and more abrupt ring profiles. Maximum latewood and minimum earlywood vary together; the greatest difference in ring uniformity is due to changes in maximum latewood. The statistics generated indicate that dendroclimatic studies of baldcypress in south Louisiana should prove fruitful. Evidence demonstrates that the species will be useful in analyzing regional anomalies, such as the low winter temperatures of the 1960{\textquoteright}s and 1976-79, and that baldcypress data may be able to be pooled with data from other species.}, url = {http://ezproxy.library.arizona.edu/login?url=http://proquest.umi.com/pqdweb?did=751675381\&sid=14\&Fmt=2\&clientId=43922\&RQT=309\&VName=PQD}, author = {Bowers, Lynne Jordan} } @mastersthesis {447, title = {Tempests, Freshets and Mackerel Skies; Climatoligical Data from Diaries using Content Analysis}, volume = {PhD}, year = {1980}, school = {University of Maine at Orono}, abstract = {For most of this century members of the scientific community have been studying the record of and reason for climate change.

Ring-width variations in stone pine near upper treeline in the Alps show a high negative correlation with the percentage of advancing glaciers in Austria and Switzerland. The relationship is due to the similarity of climatic models for tree growth and the glacial mass budget. Tree-ring fluctuations during the period 1800-1889, prior to the compilation of glacial statistics show good agreement with historical glacial advances and periods of low summer temperatures, especially around 1820-1855. Tree-ring studies could assist in reconstructing the glacial and climatic history of the Alps, possibly for a period of 1,000 years or more.

Important climatic information may be contained in long tree-ring records from the upper treeline of mid-latitude mountains. Preliminary work and the results of related research suggest that the variation in annual ring-width series from bristlecone pine (P. aristata) at the upper treeline is related to year-to-year differences in the temperature regime, in contrast to the \"drought sensitivity\" of this species near the lower forest border. Therefore, the establishment of a quantitative relationship between meterological factors and tree-ring growth at the upper treeline may permit the extension of temperature records, ad would provide an additional tool for evaluating certain environmental characteristics of remote, high-mountain regions. Direct comparison of tree-ring chronologies from \"drought-sensitive\" conifers at the lower forest border with those from \"cold-sensitive\" trees at the nearby upper treeline might also lead to the separation of precipitation and temperature effects in paleoclimatic reconstruction.

The basic approach involves the empirical comparison of tree-ring chronologies with concurrent meteorological time series in a few areas in the western United States, selected for the proximity of a bristlecone pine treeline to one or more high altitude weather stations. A number of replicated tree-ring samples will be dated, measured, standardized, and evaluated to form the basic tree-ring chronologies. testing the association between the ring-widths and meteorological factors will proceed through the development of progressively refined empirical models. Consistency with available biological data will serve as a general guide in the development of a meaningful model.

When ever possible, these dates have been presented individually along with the species, type of sample, and site provenience of every dated specimen, and an accounting has been given of the collection and present location of the pieces, the people responsible for the dating, and any previous publication of the dates. Each dated site has been discussed with respect to name, location, description, excavation, and the temporal relationship between the site and the associated tree-ring dates. It has been shown that the correct archaeological interpretation of dates depends upon the satisfactory solution of two basic problems: (1) the time relationship that exists between the date of the specimen and the archaeological manifestation being dated, and (2) the complicating factor introduced by the possibility of exterior rings lost from a dated tree-ring sample. A third requisite for correct interpretation, and understanding of the symbols used in the listing of dates, has necessitated a detailed explanation of the various forms of presentation used with Chaco Canon region dates.
