Anadromous populations of juvenile coho and cutthroat frequently occur sympatrically in coastal streams of western North America. Their apparently similar external morphology and macrodistribution in streams suggest they might broadly overlap in resource use. This study examines resource partitioning between these two salmonids in streams and in laboratory experiments. In small coastal streams, during late summer low flow, sympatric populations of juvenile coho and cutthroat were partially segre...

Sympatric populations of Dolly Varden (Salvelinus malma) and cutthroat (Salmo clarki clarki) are spatially and food segregated in Loon Lake, British Columbia. Dolly Varden are found mainly in the lower water column, while cutthroat are found in the middle and upper water column. Zooplankton, the only major prey type found in both diets, appear more important to the cutthroat. The purpose of this study was to determine whether this segregation was due to behavioural interactive processes or gene...

L'Amazonie a connu une longue histoire d'occupation humaine. La nature et l'échelle de l'impact des populations d'Amérindiens précolombiens sur leur environnement sont encore largement débattues. Dans une approche pluridisciplinaire, la thèse vise 1) à améliorer les estimations de l'étendue des remaniements anciens des paysages par l'Homme et 2) à comprendre comment ces remaniements affectent la structure et le fonctionnement des écosystèmes contemporains par l'étude des complexes de champs sur...

Ce mémoire de thèse a pour but de présenter un modèle de prédiction du transport des algues en mer le long des côtes. La méthode choisie a été d'utiliser un code industriel eulérien pour prédire l'écoulement moyen sur une grande surface, et d'ensuite ajouter un modèle lagrangien pour prédire le mouvement des particules individuelles. Ce modèle lagrangien comporte trois étapes. Premièrement, les caractéristiques moyennes du fluide trouvées avec le modèle eulérien sont utilisées pour alimenter un ...

Les estuaires et les zones côtières constituent des territoires à fort enjeux stratégiques économiquement et pour l'environnement. Ils assurent de nombreuses fonctions biologiques et écologiques dont celle de nourricerie et de frayère pour les poissons. Ces écosystèmes sont pourtant soumis à de multiples facteurs de stress, à la fois naturels et anthropogéniques, qui peuvent représenter une menace potentielle envers les organismes aquatiques, en particulier pour les espèces commerciales de poiss...

This thesis investigated the use of a static acoustic data logger known as a Cetacean and Porpoise Detection (C-POD) device for monitoring two species of dolphins that occur in Mossel Bay, South Africa: the Indo-Pacific bottlenose dolphin, Tursiops aduncus, and the Indian Ocean humpback dolphin, Sousa plumbea. These two species have a near shore distribution which brings them into frequent contact with human activities such as boating, fishing, desalination plants and the onshore component of ga...

Coastal metal pollution is a major concern to the health and well-being of aquatic organisms. Bioindicator organisms such as mussels have the potential to monitor coastal metal pollution. In New Zealand, the feasibility of employing green-lipped mussels, Perna canaliculus as a bioindicator species is yet to be investigated. This thesis focuses on applying a suite of biomarkers on green-lipped mussels exposed to cadmium (Cd) to evaluate the utility of the biomarkers and investigate the utility of...

Resprouting is an important means of plant regeneration especially under conditions that do not favour regeneration through seeding such as frequent disturbances, low productivity, unfavourable soil conditions, extreme cold and limited understorey light availability. Sprouts may be advantageous over seedlings because they have higher survival and growth rates than seedlings, since they use resources from parent plants unlike seedlings that have to acquire their own resources. Resprouting is well...

Dams and hardened levees built by European settlers in the last two centuries have degraded or stopped the cyclic sedimentation patterns that built the Mississippi River Delta Plain over the past 7,000-8,000 years. Man-made diversions of sediment-laden river water along the lower Mississippi, operated during high water periods, are being considered as a primary mechanism for combating the land loss induced by rising sea-level and these modern controls. To date, no study has documented the sedime...

In wetland sediments, organic matter provides a substrate for microbial activity. During metabolism, microbes release extracellular polymeric substances, which accumulate to bind soil particles. A similar concept can be implemented on a large scale to reduce wetland loss in Louisiana. Hypothetically, hydraulically dredged sediment can be amended with polymer and deposited on subsiding marshes as a restoration method where the polymer increases sediment stabilization until plants become establish...

The modern day Mississippi River Delta Plain and the Louisiana Chenier Plain have been greatly altered through anthropogenic changes to course and hydrological conditions of the Mississippi River and local rivers, most notably by levees that have excluded the Mississippi River from the delta plain. This has slowed accretion and increased land loss destroying vast quantities of marsh, endangering many coastal communities. This masters thesis examined long-term total suspended sediment yield of fo...

Along the Toronto shoreline, small coastal embayments (0.4 – 32 ha) are being constructed or modified to restore warmwater fish habitat. I describe how Lake Ontario (hereafter the Lake) alters the thermal regime of these small coastal embayments, how the altered thermal regimes affect growth and survival of age-0 warmwater fishes, and how the thermal habitat quality for such fishes can be improved by altering embayment design. During the warming period of the ice-free season, embayments warm fas...

There is a problematic interaction going on between grey seals and the small scale coastal fisheries in the Baltic. A large number of seals are by-caught and drowned each year, and the viability of the fishery is threatened by catch losses caused by the seals. Traditional mitigation methods are not sufficient, or have in some cases not been properly evaluated. Available methods of quantifying and analysing the catch losses are also insufficient. This thesis consists of three parts, each studying...

Coastal cutthroat trout (O. clarki clarki) rear in small, headwater streams that may be particularly susceptible to impacts from land-use activities such as logging. Headwater populations of coastal cutthroat trout were trapped from 1997 to 2002 to investigate: (i) the effects of second-growth logging on trout densities and summer body condition over summer and winter months; (ii) the influence of physical habitat characteristics on summer trout densities; and (iii) the characteristics of ...

Kinematic analysis of faults along the northern coastal plain of the Gulf of Mexico shows a correlation between pulses of faulting during the late Cenozoic and changes in the tectonic and climatic settings acting on the source areas which provide sediments to the Gulf. Pulses of faulting during the Oligocene-Early Miocene, Late Miocene, Pliocene, and Pleistocene correlate to major tectonic and climatic changes in the source region of sediments. Slip rates of faulting increase with younger events...

[Truncated abstract] Removal of consumers through fishing has been shown to influence ecosystem structure and function by changing the biomass and composition of organisms occupying lower trophic levels. The western rock lobster (Panurilus cygnus), an abundant consumer along the temperate west coast of Australia, forms the basis of Australia's largest single species fishery, with catches frequently exceeding 11000 tonnes annually. Despite their high abundance and commercial importance, the diet ...

The Maputaland Coastal Plain is situated in north-eastern KwaZulu-Natal Province, South Africa. The Maputaland Coastal Plain and underlying aquifer are two separate but inter-linked entities. This area with high permeable cover sands, low relief and regional geology that slopes towards the Indian Ocean, hosts a variety of important wetlands in South Africa (e.g. 66% of the recorded peatlands). The wetlands overlie and in some cases also connect to the underlying regional water-table. The apparen...

Every species has a limit to its geographic distribution. The problem is that we don’t really know why. Classical explanations propose that range limits occur where the ecological conditions overwhelm adaptation and populations are no longer self-sustaining. It is generally expected that population abundance and fitness decline towards range margins across a gradient of declining habitat quality. Current evolutionary and theoretical explanations of range limits predict that this geographic patte...

Contaminants introduced in solution to coastal waters eventually accumulate in sediment. Pollution by these contaminants is only evident when biological effects occur. Geochemical procedures lack the ability to identify biological effects of pollution. Biological methods (i.e. community structure analyses and/or bioassays) are currently the best available techniques for pollution assessment. Standardised and locally relevant protocols for pollution assessment are lacking in many developing count...

The vast distribution and long duration of the Late Mesozoic magmatism in the eastern part of South China presents a unique case in the world. This offers a natural laboratory to study the process of magma genesis, the magma emplacement mode, the relationship between magmatism and tectonics, the geodynamic role on the magma emplacement and lithospheric evolution. Since 50's, particularly 90's of the last century, geoscientists have made important efforts in geological cartography and carried out...

In the Pacific Northwest landslide inventories are routinely compiled by means of aerial photo interpretation. When examining photo pairs the forest canopy, notably in old-growth forest, hides a population of "not visible" landslides. The present study attempts to estimate how important is the contribution of landslides not detectable from aerial photographs, to the global mass of sediment production from mass failures on forested terrain of the Capilano basin. To achieve this, aerial phot...

Global climate change has become the imminent issue of our time. Recent literature has stressed the pressing need for adaptation planning, particularly for communities that are most vulnerable to new climatic variations, such as resource dependent and coastal communities. Yet, such cries for adaptation have often glossed over the need for prior examination into the underlying cultural mindsets of such communities. In response, this thesis has sought to examine the various factors that are influe...
