Abstract or Summary
  • Wood density is controlled to a large extent by the relative widths of earlywood and latewood in the stem, but the mechanisms controlling these amounts are poorly understood in coastal Douglas-fir. To understand the role of climatic factors, one hundred and thirty-six increment cores were collected and measured from the Salal Fields study site located in Western Oregon. Increment cores were collected from the four following heights on 38 Douglas-fir trees representing differing social positions: 1.37, 2.44, 4.88, and 7.01 m. A master chronology was constructed using the median earlywood and latewood time series for all of the increment cores collected. Statistical models indicated that earlywood growth was impacted most by temperature, while latewood growth was impacted most by the amount of summer precipitation. The site experienced disturbance events, which impacted earlywood growth in 1980 and latewood growth in 1983. The majority of variation in the master chronologies of both earlywood and latewood for this site can be explained by changes in climate and the presence of disturbance events.

  • description.provenance : Rejected by Julie Kurtz(julie.kurtz@oregonstate.edu), reason: Hi Derek, I had to reject your submission for the following reasons - 1) Abstract page is missing the abstract which should start after your major professor's name. Also on this page underline the date - July 18, 2016 2) Copyright page - remove the underline under the date - July 18, 2016 3) Title page - remove the underline under - Presented July 18, 2016 4) Remove the pages numbers in the pretext pages starting with the Table of Contents. Then start Chapter 1 Introduction on page 1 and renumber to the end. Everything else looks good. Once revised, log back into ScholarsArchive and go to the upload page. Replace the attached file with the revised PDF and resubmit. Thanks, Julie on 2016-08-09T19:41:20Z (GMT)
