The Common Tern (Sterna hirundo) is a ground nesting colonial seabird. Terns rely primarily on small prey fishes which they obtain through plunge diving for their survival as well as the survival of their offspring during the breeding season. The zebra mussel (Dreissena polymorpha) is a small bivalve mollusk that invaded North American waters in the late 1980's. Through its suspension feeding, the zebra mussel has the ability to alter the entire aquatic ecosystem, ultimately leading to a reduction in pelagic organisms including small prey fish. The objective of the study was to determine what (if any) indirect effects the invasion of the zebra mussel has had on fish prey captured by terns. The study took place in two separate two-year periods, 1990-91 and 1995-96 on a concrete breakwall off the north shore of Lake Erie near Port Colborne, Ontario. Daily nest checks revealed clutch initiation dates, egg-laying chronology, hatching success and morphological egg characteristics (length and breadth). Behavioural observations included time each sex spent in attendance with its brood, the frequency of feeding chicks and the prey species composition and size fed to chicks as well as to females (courtship feeding). Egg sizes did not differ between study periods, nor did feeding rates to chicks, suggesting that food was not a limiting resource. Terns spent less time with their broods (more time foraging) in the 1995-96 period. However, they also had significantly larger broods and fledged more offspring. The time of each individual foraging trip decreased, suggesting that fish were easier to obtain in 1995 and 1996. Lastly, kleptoparasitism rates decreased, suggesting that the costs of foraging (time, energy) actually decreased as fewer birds adopted this strategy to compensate for what I assumed to be a lack of available food (fish). The only significant difference between the periods of 1990, 1991 and 1995, 1996 was a change in diet. Terns delivered significantly fewer rainbow smelt and more emerald shiner in 1995 and 1996. However, the average size of fish delivered did not change. Thus, there was little impact on prey captured by Common Terns in Lake Erie since the invasion of the zebra mussel.

The water quality and fish populations of the Welland River were observed to decline with distance downstream. This coincided with increased agricultural , domestic and industrial waste loadings. The river upstream of the City of Welland received considerable loadings from agricultural sources. Centrarchids, sciaenids, ictalurids, cyprinids and esocids characterized this upper section of the river. Most of these species were tolerant of low dissolved oxygen concentrations and the high turbidity which prevailed there . The river near Port Robinson receives many industrial and domestic wastes as evidenced by the water quality data. The fish in this section were less abundant and the observed population was comprised almost solely of cyprinids. Further downstream, near Montrose, the Welland River received shock loads of chemical wastes that exceeded a specific conductance of ISiOOO ;umhos/cm. Few fish were captured at this site and those that were captured were considered to be transients. A review of the literature revealed that none of the common indices of water quality in use today could adequately predict the observed distributions. In addition to the above, the long-term trend (l3 yrs) of water quality of the lower Welland River revealed a gradual improvement. The major factor thought to be responsible for this improvement was the operation of the Welland Sewage Treatment Plant. The construction of the New Welland Ship Canal coincided with large fluctuations of the total solids and other parameters downstream. These conditions prevailed for a maximum of three years (1972- 1975)' Furthermore, spawning times and temperatures, geographic distributions, length-weight regressions and many other descriptive aspects of the ecology of some 26 species/ taxa of fish were obtained. Several of these species are rare or new to southern Ontario.

This thesis analyzes the practices and experiences of two groups of Canadian volunteers who visited the organic fanning and "alternative development" project ofFinca la Flor (FLF) in central Costa Rica. Using both participant observation and in-depth interviews with volunteers and other people involved with FLF, I examine volunteers' understandings of their involvement with the fann. I argue that three discursive fonnations are instrumental in shaping this particular volunteering encounter. Specifically, interpretation of these Canadian volunteers' experiences inspires the argument that the emerging practice of international volunteering (or voluntourism) exists at the intersection of discourses of development, volunteering and tourism, all of which both reflect and maintain problematic North-South relationships. The analysis shows that in spite ofFLF's construction as an (alternative / sustainable) international-development project, and in spite of volunteers' initial conceptualization of their trip as "volunteering," volunteers tend to act and describe their time at FLF in ways that look more like tourism than like volunteer labor or international development. Likewise, although FLF claims to principally be focused on alternative development, and merely to open up this authentic development space to volunteers for their participation, the organization in both practice and discourse seems primarily to construct a tourist experience and cater to the needs of foreigners as tourists. Discourses of development and volunteering do infonn the practices offann personnel and volunteers at FLF, but they become subordinated to the more dominant discourse of tourism as the volunteers' and fann management's ideals of development and volunteering capitulate to become focused on satisfying volunteers' (perceived or "real") touristic desires. The FLF participants I studied may have entered the encounter as volunteers, but they departed the site having been tourists.

During the 1950’s, the Rittenhouse family of Vineland in the Niagara Peninsula opened a craft store and studio. Within a short period of time, they realized that resources for the craft of rug hooking were in demand and they began to build their business around this niche. Edna Rittenhouse, the mother, was the wool dyer; Margaret Rowan, the daughter, was the pattern designer; Ted Rowan, the son-in-law, changed careers and became the manager of the family business. The 1960’s were a prosperous time, not only in the Niagara Peninsula, but also for the Rittenhouse business. Edna Rittenhouse had been hooking rugs for decades but she and her family worked at developing and sharing newer techniques with newer materials. Shading manuals were authored and published; students became teachers; creativity abounded in the demand for and the creation of new designs. Instead of using woolen yarn, they were using pure woolen fabric; instead of using a standard cutter, they began using a uniquely designed cutter; instead of using frames, they employed a table top method. The new material and technique resulted in a rug with a smooth, uniform texture and a soft nap. Since many crafters belonged to crafters guilds, Margaret and Ted Rowan began promoting the idea of a guild for rug hookers and in time the Ontario Hooking Craft Guild was also a reality. A joint project between Chatelaine magazine and the Rittermere studio for Canada’s centennial year of 1967 was extremely well received within the circle of hooking crafters and the Rittermere Farm Craft Studio became a North American landmark for crafters. From this point onward the studio had a large customer base not only in North America but also overseas. The studio remained popular until 1984 when Margaret and Ted Rowan decided to retire. The Rittermere name has been preserved in the name of Rittermere-Hurst-Field which is a similar business located in Aurora which is just north of Toronto.

The article focuses on three results of the study: "(1)Communicate your results outside the research. Write articles in popular and industry magazines. Speak at producer meetings and develop websites that can be used to transfer research results into practice. (2) Choose places (e.g. farms or plants) that have managers who believe in your research, and be prepared to spend a lot of time with the first place that uses your findings. (3) to fail. (4) Do not allow your technology to get tied up in patent disputes."
