The influence of macrofauna on intertidal sediment stability and biogeochemical properties.
… known to have a significant effect on intertidal sediment stability and biogeochemical properties. A series of manipulative in situ mudflat studies at Breydon Water, Great Yarmouth, UK investigated the effect of biodiversity on selected biogeochemical sedimentary properties related to mudflat …

Habitat variability and ecosystem processes in intertidal soft-sediments
Coastal and estuarine soft-sediment ecosystems are disproportionately important for ecosystem functioning (on a per m2 scale) as they serve as transitional environments, making them one of the most biologically productive places on earth. This productivity is underpinned by multiple ecosystem …

The effect of exopolymers on the compressibility and shear strength of kaolinite
… compressible. Hydraulic pumping of dredged sediment is a common method for combating damage caused by erosion and subsidence, but the high water content slurry deposited is very compressible with low shear strength. Although conventional soil amendments are effective for reducing …

Interactive processes in a Lanice conchilega (Annelida: Polychaeta) dominated intertidal community
… conducted into the factors influencing a soft-sediment intertidal benthic community dominated by the large tube building polychaete Lanice conchilega (Pallas, 1766). The environmental and biological characteristics of a mid-shore sampling site on a relatively sheltered sandflat were monitored …

The context-specific roles of a bioturbating crab (Austrohelice crassa) on ecosystem functioning
… of this species infers that its effects on sediment processes are likely to be significant. This thesis explores Austrohelice’s impact on ecosystem functioning quantifying both density and habitat induced differences in sediment reworking rates, solute and particle fluxes. The underpinning …

Comparative analysis of meiobenthic diversity across habitats in ancient lakes
… in Africa stand out for their exceptional age, stability, and high levels of endemism, making them valuable systems for studying biodiversity and evolutionary processes. These lakes, some of the oldest and most isolated globally, function as natural laboratories, providing unique insights into …

Benthic and pelagic responses to endobenthic bioturbator (Kraussillichirus kraussi) density, temperature and eutrophication in a global change mesocosm experiment
… biomass may have important implications for sediment stability and trophic resource availability for benthic feeders under future global change scenarios. Findings from Chapter 5 highlighted the importance of temperature and sandprawn density rather than eutrophication in determining …

Ecosystem metabolism in coastal plain streams of southeast Louisiana : environmental and watershed effects
Since its introduction in 1956, the use of open-system, diel dissolved oxygen curves for estimating the components of ecosystem metabolism in the lotic setting have been important in determining the current ecosystem theory of streams, both spatially among multiple systems and longitudinally within …
