Includes bibliographical references (leaves 45-56). / Unimodal patterns of diversity along gradients of both disturbance and productivity rank amongst the most celebrated generalizations in ecology, known as the Intermediate Disturbance Hypothesis (IOH) and Productivity Diversity Hypothesis. However, doubt about their generality has arisen from studies that have failed to confirm the predicted patterns. Models suggest the interactive effects of disturbance and productivity on diversity to be res...

We investigate the extent to which functional structure and spatial variability of intertidal communities coincide with major biogeographical boundaries, areas where extensive compositional changes in the biota are observed over a limited geographic extension. We then investigate whether spatial variation in the biomass of functional groups, over geographic (10′s km) and local (10′s m) scales, could be associated to species diversity within and among these groups. Functional community structure ...

Publisher version / We utilised stable isotope ratios to assess differences in diet among three indigenous and syntopic rocky shore suspension-feeders (mussels Perna perna, barnacles Tetraclita serrata, and polychaetes Gunnarea gaimardi). We also determined the spatial and temporal variability in the suspension-feeder diets by collecting specimens on two occasions from two regions adjacent to hydrologically distinct river mouths (i.e. one with larger annual freshwater throughput than the other)....

Shore zones of large rivers are hot spots of biodiversity and contribute significantly to riverine ecosystem functioning. Today, shore degradation and other structural impair-ments like river straightening and channelization are strong impact factors on river ecosystem health. However, we still lack a thorough understanding of how structural shore zone degradation affects benthic community composition and their inherent ecosystem functions. In this thesis I tested the influence of training struc...

<p> My study was designed to determine how different thermal defense strategies and the intensity of high temperature challenges might affect demographic and physiological performance of limpets on rocky shores. Found together in the high intertidal zone, <i>Lottia scabra</i> employs a constitutive thermal defense strategy, whereas <i>L. austrodigitalis</i> has an inducible one. I measured loss and growth rates of both species as a function of average daily maximum temperature exposure in the fi...

Grateloupia filicina is a carrageenophytic red alga which is in demand as a carrageenan raw material and for use in food. There is therefore interest in developing a technique for mariculturing this species. Since vegetative propagation from thallus fragments has not been successful, the present study was initiated to determine suitable conditions for spore liberation and growth of G. filicina from spores. It was also attempted to propagate G. filicina sporelings from crust and thallus fragments...

Logging constituted the first industry on the North Shore of Burrard Inlet and remained an important part of the local economy until its decline in the early 1930's. Between the 1860's and the 1930's enormous changes were made in West Coast logging technology, and lumbermen had an increasingly visible impact on the forest landscape as they employed industrial technology in the woods. Over the decades the spatial pattern of the lumber industry on the North Shore changed significantly: lumber oper...

The following research deals with the response of the small shore crabs, Hemigrapsus oreqonesis and Hemigrapsus nudus to paralytic shellfish toxins (PST). These shore crabs were shown to develop a remarkable seasonal resistance to administered saxitoxin (STX). No similar change in sensitivity was found after administration of tetrodotoxin (TTX), another marine neurotoxin with similar actions to the PST. Resistance to STX in the small shore crabs was linked to the presence of PST in the viscera, ...

Located in the middle part of the Baltic, the island of Gotland underwent major environmental changes, associated with different stages of the development of the basin during the Holocene, and therefore represents a promising location for shore-displacement studies. This thesis is focused on a palaeohydrological evolution of the Lina Mire, central eastern part of Gotland, in the Middle Holocene and aims to reconstruct the timing and environment of the Littorina transgression. The research is bas...

Numerous ecological studies have used lipids to determine trophic pathways in aquatic systems, as fatty acid profiles provide time-integrated information on an organism’s assimilated diet. Many of these studies have, however, been based on sample collections with a limited temporal scale. The trophic ecology of pelagic systems has been studied intensively using fatty acid analyses, but very little work has been directed toward benthic communities, with the intertidal being especially neglected. ...

This thesis investigates the shore processes of Lake Pukaki to assess the suitability and performance of existing and potential future options for management of shore hazards. Following two successive raisings of the water level in the past sixty years, Lake Pukaki’s shoreline has undergone extensive erosion. Since mid 1987 until early 1988, shoreline erosion control structures (i.e. rock revetments, gabion baskets and groynes) were constructed and maintained to protect sections of road and othe...

Following years of speculation about the potential economic value of mineral deposits in northeastern Minnesota, the first full-scale attempts to exploit that potential began in 1882. That year, the Minnesota Iron Company (MIC) imported dozens of miners to start extracting iron ore from the Soudan Mine on the south shore of Lake Vermilion. They concurrently imported hundreds of men to Agate Bay on the north shore of Lake Superior, approximately 70 miles south of the mine. The MIC selected Aga...

The primary object of the survey was to provide a Photographic Terrain Interpretation Key, and the organisation of field work was directed to that end. As the terrain characteristics of the survey region bad to be analysed during the preparation of the key it was also possible to prepare a geographical outline at the same time. Owing to the need for minute detail in the widespread photographs chosen for keying, a good deal of time was spent on purely photographic work at the expense of other asp...

The Hemigrapsus oregonensis population at Coquille Point in the Yaquina Bay Estuary on the Central Oregon Coast was studied from April, 1972 through May, 1973. The population was found to be vertically stratified from the 1 ft level to the 5 ft level. Population densities were found to be most dense in the upper regions. Greatest population density (about 20 crab/m²) was found to be in the 3-4 ft interval above MLLW (0.0 ft level). The population sex ratio was biased in favor of the females (53....

This thesis examines the relationship between utopianism and nationalism in New Zealand literature between 1817 and 1973. My research utilises the definition of both the utopia and the nation as “imagined” or “imaginary” communities (to use Benedict Anderson and Phillip Wegner’s terms), in demonstrating how they function as interdependent concepts in colonial New Zealand literature. Specifically, my research focuses on how a dominant discourse of Pākehā nationalism is influenced by the desires o...

[Truncated abstract] With rapidly increasing population densities along coastlines and rising global sea levels, coastal protection has become a major concern for coastal communities. Predicting sediment transport in nearshore regions, however, is one of the most challenging tasks faced by coastal researchers in designing coastal structures or beach nourishment schemes. Although nearshore sediment transport mainly occurs in the longshore direction, cross-shore sediment transport is crucial in de...
