The benthic ecology of False Bay, with notes on the analysis of shallow-water soft substrata
… a new field by tackling for the first time the ecology of the shallow sea bed. False Bay is accessible and provides a large area that is virtually unaffected by rivers or the works of man. Its situation happens to be particularly interesting. It is the nearest part of the flat, submarine shelf …

Migrations of spiny rock-lobsters, Jasus Lalandii, at Luderitz : environmental causes, and effects on the fishery and benthic ecology
… between rock-lobsters and the associated benthic species assemblage. It was found that, although there were changes in the benthos (notably an increase and subsequent decline in whelk density), these were unrelated to variation in rock-lobster density. In addition, no relationship between …

High Resolution Paleolimnology of Lakes in the Athabasca Oil Sands Mining Region, Alberta, Canada
… climate anomalies influence lake hydrology and ecology. Deconvolution of the grain size spectra indicates that populations are likely responding to overarching environmental controls. The coarser bedload material was interpreted to reflect high discharge events that occur during spring melts. A …

Spatial distribution and conservation planning of seabed biological diversity
… a way of addressing issues of fundamental ecology relating to the processes influencing the variation of ecosystem structure across space. The present thesis is concerned with methods (and related issues) to document the spatial distribution of diversity at the assemblage (or community) …

Vertical distributions of megafauna on inactive vent sulfide features correspond to their feeding modes
… knowledge gaps in the distribution and feeding ecology of communities inhabiting this type of deep-sea habitat. Previous seafloor imaging studies indicate that megafaunal taxa on inactive sulfides are not endemic to these features, but their assemblages differ from other deep-sea habitats. I …

The physical and ecological impacts of mangrove expansion and mangrove removal: Tauranga Harbour, New Zealand
… perceive this change to be detrimental to the ecology and aesthetics of their estuaries, yet little empirical data is available to support these perceptions. Coastal managers are presently developing management strategies associated with either the maintenance or the removal of mangrove habitat …

Denitrification response to nutrient enrichment in New Zealand estuaries
As coastal catchment land use intensifies, estuaries receive increased nutrient and sediment loads, resulting in habitats dominated by muddy organic-rich sediments. Nutrient processing and denitrification in estuarine sediments represent important ecosystem functions regenerating nutrients for …

Effects of watershed land use on the benthic macroinvertebrate assemblages in ridge and valley streams in Chattanooga, Tennessee
… across study sites. Habitat conditions and benthic indices varied between sites within study streams. This study revealed relationships between benthic indices and water quality, habitat conditions and land use. Relationships between watershed land use and instream substrate ( cobble and …
