Ecophysiological assessment of western hemlock and western red cedar greenhouse stocktypesMajor, John E. January 1990 (has links)
Western hemlock (Tsuga heterophylla (Raf.) Sarg.) and
western red cedar (Thuja plicata Donn) seedlings from four
dormancy induction treatment(s) (DIT) (i.e. long-day dry,
long-day wet, short-day dry, and short-day wet) were planted
on a high available soil moisture field site in British
Columbia and monitored for physiological response and
morphological development over the first growing season.
Stomatal conductance (gwv) and net photosynthesis (Pn) were
recorded over an environmental matrix of photosynthetically
active radiation (PAR) (0 - 2.2 mmol m⁻² s⁻¹ ) and vapour pressure deficit (VPD) (0 - 2.5 or 4.0 kPa) on both first year grown and fully developed second year foliage. To compare stocktypes, physiological data were collected and analyzed in the following ways: (1) replicated data at stable environmental conditions once a month, (2) physiological response to one increasing environmental variable using boundary line analysis, and (3) physiological response surface to two simultaneously changing environmental variables.
For western hemlock first year needles, short-day DIT had a higher gwv response to both increasing VPD and PAR. Both short-day and moisture stressed DIT improved Pn response to PAR, and the combination had the highest response. Short-day DIT seedlings initially were smaller, shorter, had a better seedling water balance ratio and lower shoot to root ratio. Short-day second year needles showed a slightly higher gwv response to both increasing VPD and PAR as compared to long-day seedlings; however, they showed no treatment differences for Pn versus PAR. All stocktypes had similar final morphological parameter values.
For western red cedar first year foliage, moisture stressed DIT seedlings had greater Pn response to increasing PAR and VPD. Also, moisture stressed seedlings gwv response to increasing VPD and PAR was higher when compared to its' non moisture stressed daylength counterpart. The long-day wet seedlings initially had a larger root and shoot system as compared to the other stocktypes. Second year foliage exhibited no treatment differences for gwv and Pn response to PAR ' and VPD. All stocktypes had similar final morphological parameter values.
Attempts to test stocktypes at stable environmental conditions proved, at times, difficult. Potentially large measurement variation due to atmospheric environmental changes, and not stocktype effect, could result. Boundary line analysis, when used correctly and with sufficient data, offers a good stocktype assessment method which enables the isolation of a physiological response to one environmental variable. Three dimensional surface response technique was required to provide a clear conceptual representation of two primary environmental variables' influence on seedling physiological response. / Forestry, Faculty of / Graduate

Dendroarchaeological and contextual investigations of remote log structures in Jasper, Banff, and Kootenay national parks, CanadaBrelsford, Karen Jacqueline. 10 April 2008 (has links)
The aim of this thesis is to undertake a comprehensive dendroarchaeological-contextual investigation of 35 sites (44 log structures) in Jasper, Banff, and Kootenay National Parks. Through tree-ring analysis and investigations of relevant documents (i.e., archives and interviews), three main objectives are met: 1) an architectural inventory and tree-ring analysis of sampled structures in the three parks; 2) an exploration of remote construction activity in the three parks, in terms of functional, temporal, and spatial distributions, and tree species selection; and 3) a detailed dendroarchaeological-contextual investigation of three structure case studies. The results provide new insights into remote construction activity from the late-nineteenth to early-twentieth century in the three parks. It assists Parks Canada in their attempt to interpret the cultural heritage resources of this area and contributes to the international need to document and explore vernacular architecture.

<i>Dances with Wolves</i> in space : aliens and alienation in James Cameron's <i>Avatar</i>Sutherland, Aaron 05 October 2010 (has links)
This paper examines critical responses to James Camerons most recent film, <i>Avatar</i>, to suggest that the ways in which critics have ignored its content because of Camerons innovative use of 3-D technology and effects or praised its content for offering a multicultural paradise are misguided at best and misleading at worst. Instead, what follows is an investigation into <i>Avatar</i>s content, specifically its plot, hero and, ultimately, its indivisible relationships to the Western genre and what I call the New Western genreKevin Costners <i>Dances with Wolves</i> (1990) will be representative of the larger genre which has continued to emerge in more recent films like Edward Zwicks <i>The Last Samurai</i> (2003). These relationships between, and crossovers within, genres prevent cross-cultural relationships based upon democratic forms of equality, what Costner is moving toward and what Cameron makes a claim for, from coming to fruition. As biological (colonial) and social/historical (imperial) notions of racial superiority and inferiority move across and arise within genres, the brief moments of cross-cultural cooperation and mutual respect within these films are subverted. In fact, Camerons film very clearly demonstrates how politics can be mobilized, despite a filmmakers unawareness, through big-budget blockbusters to advocate concrete and damaging political projectsin this case, Americas imperial projects around the globe. This paper attempts to do two main things: show how Cameron fails to notice what is a very clear advocacy for American imperialism in his film and display the ways in which a lasting egalitarian model of cross-cultural social organization is never established as a result of this failure.

Regional alienation : understanding political culture, regionalism and discontent in western CanadaPortengen, Michael Bernard 05 1900 (has links)
While western regional alienation has been the subject of much scholarly and public debate
in Canada, we still know relatively little about the factors driving the phenomenon. Relying upon
survey data collected in the 1997 Canadian Election Study (CES), this study attempts to
substantively quantify western regional alienation and identify its correlates. Using the existing
literature as a starting point, the study examines how western regionalism and political culture are
typically conceptualized and identifies several factors commonly said to propel regional unrest and
western 'distinctiveness.' Regression analysis is used to systematically test the accuracy of existing
theories concerning western regional alienation. The study contends that while the four western
provinces do not hold a monopoly on feelings of regional alienation, levels of unrest are indeed
higher in the West than in other parts of the country. Regional alienation is also distinguished from
more general understandings of political apathy or cynicism. Finally, with respect to the factors said
to propel regional unrest, antipathy towards Quebec and Outgroups are shown to be the most
important predictors or regional alienation - while attitudes concerning the economy, populism,
social programs, law and order and continentalism have a weaker effect. However, even after
controlling for these factors, significant regional differences remain. Thus, other factors - as-of-yet
unaccounted for - must also play a role.
