A comparative study of the change in diatom inferred ph of a staircase of lakes in the Algoma District, Northern Ontario /

Four staircase lakes occupying a single watershed located in the Algoma District, north of Lake Superior were chosen for this study. I examined the subfossil diatom assemblage in the top twenty centimeters of the surface sediments in each of these four lakes in an attempt to reconstruct their respective past pH history. From these analyses it was possible to test the hypothesis that the rate of change of diatom inferred pH was not significantly different in lakes located one below the other in a single "staircase" within a single watershed system. My results indicated that the four Z lakes had been acid for at least the last century. The water color of the three upper Z lakes (Z1, Z2 and Z3) was brown (>30 Pt Co units). The bottom lake (Z4) was the only clear water lake in the system «5 Pt Co units). This bottom staircase lake had no muskeg development around its shoreline. The alkaliphilous diatoms in the Z watershed system were important in determining the diatom inferred pH of the four Z lakes. The centric diatoms were extremely rare in the clearwater bottom lake (Z4). The ecology of the Eupodiscales is perhaps important in the interpretation of sediment in the more acid environment. Lake Z4 was the only one that had a progressive as well as a significant decrease in its downcore diatom inferred pH since the early 1960's. This lead me to speculate that the humic substances present in the upper three brown water lakes (Z1, Z2 and Z3) were perhaps Important in buffering them against a further decrease in water pH even though they were located within an area which was sensitive to acid precipitation.

Paleolimnology of selected Precambrian Shield lakes /

The analysis of fossil diatoms and Mallomonas assemblages in a 2.85 m sediment core revealed that a series of distinct floristic changes have occurred in the development of Found Lake, a small Shield lake in southern Ontario. Climatic and vegetational changes in the lake's watershed were closely associated with successional changes in the lake's biota. Nutrients released by the deciduous component of the Found Lake watershed appeared to be especially important in determining diatom and Mallomonas standing crop. The top 20 cm of sediment of 3 ,Shield lakes was then investigated using close interval (1 cm) analyses of diatoms, Mallomonas scales, pollen grains and sedimentary phosphorus. Found and Jake Lake are adjacent to Highway 60, whereas Delano Lake has been undisturbed and was used as a control. Dramatic changes in the diatom and Mallomonas communities were recorded in the Found and Jake Lake stratigraphies and could be closely associated with known historical events. Increased turbidity and nutrient enrichment were believed responsible for these successional changes. In addition, diatom and Mallomonas standing crop increased substantially following road construction in Found Lake's drainage basin. Meanwhile, no. sharp changes in diatom or Mallomonas communities were recorded in the recent sediments of the control (Delano) lake. The use£ulness o£ Synuracean scales as paleoindicators, as well as the importance o£ sectioning cores at close intervals during transition periods in a laker's development, was stressed.

To see and to touch : God, honour, and irony in Shakespeare's English histories /

Failed and fragile states that result from intrastate war pose severe threats to the security of both the international system and individual states alike. In the post-Cold War era, the international community has come to recognize the reality of these threats and the difficulty involved in ending violence and building sustainable peace in failed and fragile states. This work focuses upon the development of a comprehensive strategy for sustainable peace-building by incorporating the tenets of the human security doctrine into the peace-building process. Through the use of case studies of The Former Yugoslav Republic of Macedonia and East Timor, the development and refinement of the doctrine of human security will occur, as well as, an understanding of how and where human security fits into the sustainable peace-building equation. The end result of the analysis is the development of a hierarchical pyramid formation that brings together human security and peace-building into one framework that ultimately creates the foundation and structure of sustainable peace-building. With the development of a sustainable peace-building structure based upon the human security doctrine, the role of Canada in the support of sustainable peace-building is analyzed in relation to the form and level of involvement that Canada undertakes and contributes to in the implementation and support of sustainable peace-building initiatives. Following from this, recommendations are provided regarding what role(s) Canada should undertake in the sustainable peace-building process that take into consideration the present and likely future capabilities of Canada to be involved in various aspects of the peace-building process. ii This paper outlines the need for a peace-building strategy that is designed to be sustainable in order that failed and fragile states resulting from intrastate conflict do not regress or collapse back into a condition of civil war, and subsequently designs such a strategy. The linking of peace-building and human security creates the required framework from which sustainable peace-building is derived. Creating sustainable peace is necessary in order to increase the likelihood that both present and future generations existing in failed and fragile states will be spared from the scourge of intrastate war.
