The coastal fish community of Wemindji, eastern James Bay, was studied to describe seasonal utilization of the Maquatua River estuary and the adjacent coastal waters by marine and anadromous fishes. During summer, the estuarine fishes are numerically dominated by the fourhorn sculpin (Myoxocephalus quadricornis) and the slender eelblenny (Lumpenus fabricii), and also by juvenile cisco (Coregonus artedii) and whitefish (C. clupeaformis). In coastal waters, three marine species are abundant: the shorthorn sculpin (M. scorpius), the arctic sculpin (M. scorpioides) and the Greenland cod (Gadus ogac). / Greenland cod were studied in the same period. During the summer, they principally occupied shallow coastal waters, characterized by a belt of eelgrass (Zostera marina). In winter, more cod were found in the estuary. This movement corresponds to sexual maturity; spawning occurs in April to June. Greenland cod life history variables differ from those of most arctic benthic fishes: they show rapid growth, high fecundity, low age at first maturity and high mortality.

Horseshoe Bay, British Columbia is: 1) a geographically constricted waterfront neighbourhood of the Municipality of West Vancouver, 2) a north facing deep water ocean bay with a history of marine access and activities, 3) the site of one of the busiest terminals on the British Columbia Ferry Corporation system with 2.6 million vehicles and 7 million passengers per year. The ferry corporation is planning to expand the vehicle holding lots and administration facilities in 2001 and there are public concerns about possible degradation of the character and environment of the community. The Municipality of West Vancouver has expressed a desire to rebuild the foreshore embankment of the waterfront in Horseshoe Bay Park and upgrade the various amenities. Merchants of Horseshoe Bay are concerned that changes to the pedestrian access from the ferry terminal lots may negatively affect their business. The federal government is in the midst of divesting itself of ownership and responsibility for the public wharf. These are the issues and factors that were considered in a project where several different landscape locations with different functions within the Horseshoe Bay community were the subject of a redesign program. The proposed interventions range from environmental graphics to intertidal infill and wetland construction. Each of the various proposals has a different focus, use or function but all share the common theme of landscape connectivity, linking the community to the environment in a mutually beneficial way. / Applied Science, Faculty of / Architecture and Landscape Architecture (SALA), School of / Graduate

The coastline of Florida has been formed by geomorphic processes which have created suitable habitats for certain vegetation and organisms. One type of vegetation is the mangrove; this plant has a latitudinal range of 24° to 32° N latitude which is associated with local climatic changes (Mitsch 2000). There are three species of mangrove found in Florida: red (Rhizophora), black (Avicennia), and white (Languncularia) (USGS 2006). Mangroves have adapted overtime to live in different ecosystems which cause mangroves, along the Florida coast, of the same species not be the same. Climatic variation causes individual mangrove trees have structural differences such as: tree height, diameter, and density; these variations are related to geographic location (Pool 1997, Schaeffer-Novelli 1990). Tree height is the measurement from the base of the tree trunk of the ground to the top of the tree. The diameter, also known as diameter at breast height (DBH), is the circumference of the tree trunk 1.21 meters from the ground. Density is the frequency of individual tress within predetermined distance. Florida's southwest coast has one of the world's biggest mangrove swamps called Ten Thousand Islands (Mitsch 2000). In northern Florida the mangrove swamps begin to mix with salt marsh vegetation, here mangroves are more like shrubs than trees (Mitsch 2000). The changes in individual mangrove structure could be a result of available freshwater and temperature. This project was a quantitative analysis using published and original data for graph production to understand the structural variation of mangroves on Florida's gulf coast at different latitudes. Study sites were located in bays along the Gulf of Mexico. The gulf coast of Florida was the study area of this project because it is the northern latitudinal limit for mangroves and as the latitude changes mangrove plant structure changes (Mitsch 2000). The tree height, diameter, basal area, biomass, and densities were compared to the precipitation and temperature values to understand the effect climate has on mangroves.
