Masters Thesis. Structural, cytological and chemical data are used to establish synonymy, taxonomic relationships and a classification of the herbaceous taxa of Cornus L.
Masters thesis. Statistical analysis of 47 quantitative characters, including chromosome numbers, geographic distributions, and ecological preferences used to diagnose each species of Carex macloviana in western Canada and Alaska.
Age determination of a long-lived coregonid from the Canadian North: comparison of otoliths, fin rays and scales in inconnu (Stenodus leucichthys)Download
We examined otoliths, pelvic fin rays and scales of inconnu to determine precision of age estimates within and between readers, and to compare relative accuracy of estimates from different structures. Our main objective was to determine if readability and estimates from fin rays and scales,...
Horizontal advection has been assumed negligible within the Alaskan Gyre (AG). With the recently available Argo data this assumption can be tested. To estimate advection, the observed heat content (estimated from Argo data) was compared to the expected (based on surface heat fluxes) and the...
Doctoral thesis. Critically reviews the art of phytolith analysis and presents new techniques to collection of samples, processing, mounting, and optical and SEM microscopic analyses. Includes results of analyses of samples from the Old Crow Basin, Yukon and lake areas in Alaska.
Subfossil bryophytes in eastern Beringia: their paleoenvironmental and phytogeographical significanceDownload
Doctoral thesis. Bryophytes, more particularly mosses, are used in the paleoenvironmental reconstruction and historical biogeography of eastern Beringia, an area including Alaska and the Yukon. The Old Crow Basin in northern Yukon was studied in detail. // Appendix 2: Subfossil bryophytes...
In this dissertation, tephrostratigraphy is used as the central method to address issues of chronology in the late Quaternary sedimentary record of eastern Beringia (non-glaciated Yukon and Alaska) at a variety of spatial and temporal scales. The Palisades, central Alaska, preserves...
This thesis contributes to the development of a cryptotephra framework in northwestern North America, providing the initial data for the construction of a regional cryptotephra framework where key cryptotephra layers (those which are widely distributed, easily correlated, and have well...
